DESCRIPTION DETAILLEEDETAILED DESCRIPTION Lanterneauskylight

La figure 1 et la figure 2 illustrent un dispositif d'éclairage, plus particulièrement appelé lanterneau 1, qui est une construction destinée à surmonter un bâtiment (non représenté), typiquement pour en assurer l'éclairage. Plus précisément, le lanterneau 1 est prévu pour être rapporté et fixé sur une couverture (non représentée), de préférence étanche, d'un bâtiment. La couverture peut être une toiture, un toit ou une terrasse. De préférence, la couverture est un plancher, lequel est relativement plat, c'est-à-dire qu'il s'étend selon un plan sensiblement parallèle au sol sur lequel le bâtiment est construit.There figure 1 and the figure 2 illustrate a lighting device, more particularly called a skylight 1, which is a construction intended to overcome a building (not shown), typically to provide lighting. More specifically, the skylight 1 is designed to be attached and fixed to a cover (not shown), preferably waterproof, of a building. The cover can be a roof, a roof or a terrace. Preferably, the cover is a floor, which is relatively flat, that is to say it extends along a plane substantially parallel to the ground on which the building is constructed.

Le lanterneau 1 est rapporté et fixé sur la couverture au niveau d'une ouverture traversante (non représentée) pratiquée à travers la couverture, de sorte à définir un volume fermé par un vitrage 2 et ouvert sur l'intérieur du bâtiment. Dans ce qui suit, les termes « interne » et « externe » font référence à la position d'un élément vis-à-vis de ce volume, un élément interne faisant face au volume, tandis qu'un élément externe fait face à l'extérieur du bâtiment. De même, les termes « supérieur » et « inférieur » font référence à la position d'un élément par rapport à la couverture, un élément supérieur étant plus éloigné de la couverture qu'un élément inférieur, une fois le lanterneau 1 fixé sur la couverture.The skylight 1 is attached and fixed to the cover at the level of a through opening (not shown) made through the cover, so as to define a volume closed by a glazing 2 and open to the interior of the building. In the following, the terms "internal" and "external" refer to the position of an element in relation to this volume, an internal element facing the volume, while an external element faces the building exterior. Similarly, the terms "upper" and "lower" refer to the position of an element with respect to the cover, an upper element being farther from the cover than a lower element, once the skylight 1 has been fixed to the blanket.

Un tel lanterneau 1 est parfois appelé éclairage zénithal, puits de lumière ou lucarne de toit. Comme il sera détaillé ci-après, le lanterneau 1 est résistant au feu, c'est pourquoi il est désigné comme un lanterneau 1 pare-flammes ou coupe-feu. Plus précisément, le lanterneau 1 est configuré pour limiter la propagation d'un incendie se déclarant au sein du bâtiment, en conservant, le plus de temps possible, une étanchéité aux flammes et aux fumées qui pourraient s'échapper par le lanterneau 1. Such a skylight 1 is sometimes referred to as overhead lighting, a skylight or a roof skylight. As will be detailed below, the skylight 1 is fire-resistant, which is why it is designated as a flame-arresting or fire-breaking skylight 1 . More specifically, the skylight 1 is configured to limit the spread of a fire breaking out within the building, while maintaining, for as long as possible, a seal against flames and smoke that could escape through the skylight 1.

Comme visible sur la figure 1 et sur la figure 2 , le lanterneau 1 comprend une costière 3, le vitrage 2 et une parclose 4, le vitrage 2 étant positionné entre la parclose 4 et la costière 3. As seen on the figure 1 and on the figure 2 , the skylight 1 comprises a curb 3, the glazing 2 and a glazing bead 4, the glazing 2 being positioned between the glazing bead 4 and the curb 3.

Dans la mesure où le lanterneau 1 recouvre et entoure l'ouverture traversante pratiquée à travers la couverture, il est nécessaire de maintenir l'étanchéité de la couverture au niveau du lanterneau 1. Pour ce faire, le lanterneau 1 comprend, de préférence, un joint 5 agencé entre le vitrage 2 et la costière 3, comme par exemple visible sur la figure 7 , mais aussi un joint (non représenté) agencé entre la parclose 4 et la costière 3. En outre, un joint (non représenté) peut être prévu pour être positionné entre le lanterneau 1 et la couverture.Insofar as the skylight 1 covers and surrounds the through opening made through the cover, it is necessary to maintain the tightness of the cover at the level of the skylight 1. To do this, the skylight 1 preferably comprises a seal 5 arranged between the glazing 2 and the curb 3, as for example visible on the figure 7 , but also a seal (not shown) arranged between the glazing bead 4 and the curb 3. In addition, a seal (not shown) can be provided to be positioned between the skylight 1 and the cover.

En outre, il est nécessaire d'assurer, au niveau du lanterneau 1, une continuité de l'isolation thermique de la couverture vis-à-vis du bâtiment. Pour ce faire, le lanterneau 1 comprend de préférence un matériau isolant thermiquement (non représenté) entourant au moins une partie de la costière 3, au niveau d'une surface externe de la costière 3. In addition, it is necessary to ensure, at the level of the skylight 1, a continuity of the thermal insulation of the cover vis-à-vis the building. To do this, the skylight 1 preferably comprises a thermally insulating material (not shown) surrounding at least a part of the curb 3, at the level of an external surface of the curb 3.

Costièrecurb

En référence à la figure 1 , à la figure 2 et à la figure 3 , la costière 3 comprend une base 30 adaptée pour être fixée sur la couverture, un rebord 31 adapté pour supporter le vitrage 2, lequel est donc en appui sur le rebord 31 de la costière 3, et un corps 32 reliant la base 30 au rebord 31. With reference to the figure 1 , at the figure 2 and at the picture 3 , the curb 3 comprises a base 30 adapted to be fixed on the cover, a rim 31 adapted to support the glazing 2, which is therefore resting on the rim 31 of the curb 3, and a body 32 connecting the base 30 to the rim 31.

De préférence, au moins un orifice de fixation 300 est pratiqué à travers la base 30 et prévu pour fixer la base 30 à la couverture. Un élément de fixation (non représenté), tel qu'une vis ou une cheville, peut alors être prévu pour coopérer avec l'orifice de fixation 300 afin de fixer la base 30 sur la couverture. Dans une variante illustrée sur la figure 1 , sur la figure 3 et sur la figure 4 , une pluralité d'orifices de fixation 300 est pratiquée à travers la base 30, et se trouve, par exemple, répartie tout autour de la base 30, une pluralité d'éléments de fixation étant alors prévus pour coopérer avec les orifices de fixation 300 afin de fixer la base 30 sur la couverture. Ceci n'est toutefois pas limitatif puisque tout mécanisme de fixation approprié peut être prévu pour fixer la base 30 à la couverture, tant que la fixation assure le maintien du lanterneau 1 sur la couverture de manière étanche et robuste.Preferably, at least one fixing hole 300 is formed through the base 30 and provided to fix the base 30 to the cover. A fixing element (not shown), such as a screw or a plug, can then be provided to cooperate with the fixing hole 300 in order to fix the base 30 on the cover. In a variant illustrated on the figure 1 , on the picture 3 and on the figure 4 , a plurality of fixing holes 300 is made through the base 30, and is, for example, distributed all around the base 30, a plurality of fixing elements then being provided to cooperate with the fixing holes 300 in order to fix the base 30 on the cover. However, this is not limiting since any suitable fixing mechanism can be provided for fixing the base 30 to the cover, as long as the fixing ensures that the skylight 1 is held on the cover in a sealed and robust manner.

Dans une variante (non représentée), la base est rapportée et fixée sur le corps, par exemple par soudure. Le cas échéant, un cordon de soudure est prévu au niveau d'une surface interne de la jonction entre la base et le corps et/ou un autre cordon de soudure est prévu au niveau d'une surface externe de la jonction entre la base et le corps. Dans une autre variante (non représentée), la base est rapportée et fixée au corps au moyen d'un dispositif de fixation comprenant une colle et un rivet, comme décrit plus en détails ci-après en référence au mode de fixation d'un premier bord 321 et d'un deuxième bord 322 du corps 32 de la costière 3. Ceci n'est toutefois pas limitatif puisque, dans une autre variante, par exemple illustrée sur la figure 1 , sur la figure 2 , sur la figure 3 et sur la figure 4 , la base 30 est venue de matière avec le corps 32, comme également décrit plus en détail ci-après. En tout état de cause, la liaison entre la base 30 et le corps 32 assure la continuité mécanique entre la base 30 et le corps 32, tout en garantissant l'étanchéité de la costière 3. In a variant (not shown), the base is attached and fixed to the body, for example by welding. If necessary, a weld bead is provided at an internal surface of the junction between the base and the body and/or another weld bead is provided at an external surface of the junction between the base and the body. In another variant (not shown), the base is attached and fixed to the body by means of a fixing device comprising an adhesive and a rivet, as described in more detail below with reference to the method of fixing a first edge 321 and a second edge 322 of the body 32 of the curb 3. This is however not limiting since, in another variant, for example illustrated in the figure 1 , on the picture 2 , on the picture 3 and on the figure 4 , base 30 is integral with body 32, as also described in more detail below. In any case, the connection between the base 30 and the body 32 ensures the mechanical continuity between the base 30 and the body 32, while guaranteeing the tightness of the curb 3.

De préférence, comme visible sur la figure 1 , sur la figure 2 , sur la figure 3 et sur la figure 7 , le rebord 31 présente une section transversale comprenant une première portion 311 permettant de supporter le vitrage 2, et une deuxième portion 312 assurant le guidage de fluide qui aurait pu s'infiltrer entre la parclose 4 et le vitrage 2, vers l'extérieur du lanterneau 1. Plus précisément, la deuxième portion 312 permet d'éviter que du fluide puisse s'écouler sur le matériau isolant, lequel est susceptible de se détériorer, ce qui est susceptible d'endommager la costière 3. La section transversale est prise de manière orthogonale à une direction d'extension privilégiée d'au moins une partie du rebord 31. La section transversale peut typiquement prendre une forme de L, la première portion 311 et la deuxième portion 312 formant alors les deux branches du L, ou de C, la première portion 311 formant une branche du C et la deuxième portion 312 formant la base du C.Preferably, as seen on the figure 1 , on the figure 2 , on the picture 3 and on the figure 7 , the flange 31 has a cross section comprising a first portion 311 for supporting the glazing 2, and a second portion 312 ensuring the guiding of fluid which could have infiltrated between the glazing bead 4 and the glazing 2, towards the outside of the skylight 1. More specifically, the second portion 312 prevents fluid from flowing onto the insulating material, which is likely to deteriorate, which is likely to damage the curb 3. The cross section is taken from manner orthogonal to a preferred direction of extension of at least part of the flange 31. The cross section can typically take the shape of an L, the first portion 311 and the second portion 312 then forming the two branches of the L, or of the C , the first portion 311 forming a branch of the C and the second portion 312 forming the base of the C.

Dans une variante (non représentée), le rebord est rapporté et fixé sur le corps, par exemple par soudure. Le cas échéant, un cordon de soudure est prévu au niveau d'une surface interne de la jonction entre le rebord et le corps et/ou un autre cordon de soudure est prévu au niveau d'une surface externe de la jonction entre le rebord et le corps. Dans une autre variante, le rebord est rapporté et fixé au corps au moyen d'un dispositif de fixation comprenant une colle et un rivet, comme décrit plus en détails ci-après en référence au mode de fixation du premier bord 321 et du deuxième bord 322 du corps 32 de la costière 3. Ceci n'est toutefois pas limitatif puisque, dans une autre variante, par exemple illustrée sur la figure 1 , sur la figure 2 , sur la figure 3 et sur la figure 4 , le rebord 31 est venu de matière avec le corps 32, comme également décrit plus en détail ci-après. En tout état de cause, la liaison entre le rebord 31 et le corps 32 assure la continuité mécanique entre le rebord 31 et le corps 32, tout en garantissant l'étanchéité de la costière 3. In a variant (not shown), the flange is attached and fixed to the body, for example by welding. If necessary, a weld bead is provided at an internal surface of the junction between the flange and the body and/or another weld bead is provided at an external surface of the junction between the flange and the body. In another variant, the flange is attached and fixed to the body by means of a fixing device comprising an adhesive and a rivet, as described in more detail below with reference to the method of fixing the first edge 321 and the second edge 322 of the body 32 of the curb 3. This is however not limiting since, in another variant, for example illustrated in the figure 1 , on the figure 2 , on the picture 3 and on the figure 4 , flange 31 is integral with body 32, as also described in more detail below. In any case, the connection between the flange 31 and the body 32 ensures the mechanical continuity between the flange 31 and the body 32, while guaranteeing the tightness of the curb 3.

En référence à la figure 1 , à la figure 3 et à la figure 4 , le corps 32 comprend le premier bord 321 et le deuxième bord 322. En outre, la costière 3 comprend un dispositif de fixation prévu pour fixer le premier bord 321 sur le deuxième bord 322. With reference to the figure 1 , at the picture 3 and at the figure 4 , the body 32 comprises the first edge 321 and the second edge 322. In addition, the curb 3 comprises a fixing device provided for fixing the first edge 321 to the second edge 322.

Le dispositif de fixation comprend une colle et au moins un rivet, au moins un orifice 323 en regard étant pratiqué, respectivement, à travers chacun du premier bord 321 et du deuxième bord 322, afin d'accueillir le rivet. Grâce à la combinaison de la colle et du rivet, la jonction entre le premier bord 321 et le deuxième bord 322 demeure étanche à des températures très importantes, ce qui permet au lanterneau 1 de résister au feu plus longtemps. De fait, ni flamme ni fumée n'est susceptible de s'échapper par la jonction entre le premier bord 321 et le deuxième bord 322, et ce malgré les sollicitations à l'ouverture de la jonction suite à la dilatation de la costière 3 soumise à de très hautes températures.The fastening device comprises an adhesive and at least one rivet, at least one facing orifice 323 being formed, respectively, through each of the first edge 321 and the second edge 322, in order to accommodate the rivet. Thanks to the combination of the glue and the rivet, the junction between the first edge 321 and the second edge 322 remains sealed at very high temperatures, which allows the skylight 1 to withstand the fire longer. In fact, neither flame nor smoke is likely to escape through the junction between the first edge 321 and the second edge 322, despite the stresses at the opening of the junction following the expansion of the curb 3 subjected at very high temperatures.

De préférence, le dispositif de fixation est constitué de colle et d'une pluralité de rivets, des orifices 323 correspondants, par exemple visibles sur la figure 4 , étant prévus à travers chacun du premier bord 321 et du deuxième bord 322, afin d'accueillir les rivets. Le nombre et l'espacement des rivets (et des orifices 323) dépend de la forme de la costière 3, et plus précisément de la forme du corps 32. Par exemple, le premier bord 321 et le deuxième bord 322 peuvent comprendre chacun au moins trois orifices 323 traversants prévus pour recevoir les rivets, chaque orifice 323 étant distant d'un orifice 323 adjacent du même bord 321, 322 d'une distance d'au plus 150 millimètres.Preferably, the fixing device consists of glue and a plurality of rivets, corresponding orifices 323 , for example visible on the figure 4 , being provided through each of the first edge 321 and the second edge 322, in order to accommodate the rivets. The number and the spacing of the rivets (and of the orifices 323 ) depends on the shape of the curb 3, and more precisely on the shape of the body 32. For example, the first edge 321 and the second edge 322 can each comprise at least three through holes 323 provided to receive the rivets, each hole 323 being distant from an adjacent hole 323 of the same edge 321, 322 by a distance of at most 150 millimeters.

La colle est adaptée pour supporter des températures importantes, typiquement des températures pouvant atteindre 1000°C. Plus précisément, la colle ne coule, ni ne fond, ni ne s'enflamme, même si elle portée à de telles températures, gardant ainsi ses propriétés adhésives.The adhesive is suitable for withstanding high temperatures, typically temperatures that can reach 1000°C. More precisely, the glue does not flow, nor melt, nor ignite, even if it is brought to such temperatures, thus retaining its adhesive properties.

Dans une variante, les rivets comprennent de l'acier inoxydable, voire sont constitués d'acier inoxydable, dont le comportement thermique à très haute température est également favorable au maintien de l'étanchéité de la jonction entre le premier bord et le deuxième bord.In a variant, the rivets comprise stainless steel, or even consist of stainless steel, the thermal behavior of which at very high temperature is also favorable to maintaining the tightness of the junction between the first edge and the second edge.

Le corps 32 peut prendre différentes formes, suivant l'éclairage souhaité au sein du bâtiment, et/ou l'esthétisme recherché.The body 32 can take different forms, depending on the desired lighting within the building, and/or the desired aesthetics.

De préférence, le corps 32 est un cylindre, c'est-à-dire qu'il présente une surface réglée dont les génératrices sont parallèles, c'est-à-dire une surface dans l'espace constituée de droites parallèles. Une surface réglée est en effet une surface par chaque point de laquelle passe une droite, appelée génératrice, contenue dans la surface. Les droites génératrices de la surface du corps 32 sont toutes parallèles à un axe central X-X du corps 32 le long duquel le corps 32 s'étend. En d'autres termes, le corps 32 présente une forme allongée entourant l'axe central X-X, de préférence en étant centré autour de cet axe central X-X. L'axe central X-X est, de manière privilégié, orthogonal au plan dans lequel s'étend la couverture au niveau du lanterneau 1. Ceci n'est cependant pas limitatif, puisque l'axe central X-X peut ne pas être orthogonal au plan dans lequel s'étend la couverture au niveau du lanterneau 1. En fait, le corps 32 forme un solide, ou polyèdre, ou prisme, délimité par une surface cylindrique et par deux plans ouverts, formant les bases du cylindre formant le corps 32, qui sont strictement parallèles, les plans étant, respectivement, constitués par le plan dans lequel s'étend le vitrage 2 d'une part, et par le plan dans lequel s'étend l'ouverture traversante à travers la couverture d'autre part.Preferably, the body 32 is a cylinder, that is to say it has a ruled surface whose generatrices are parallel, that is to say a surface in space consisting of parallel straight lines. A ruled surface is indeed a surface through each point of which passes a straight line, called generatrix, contained in the surface. The generating lines of the surface of the body 32 are all parallel to a central axis XX of the body 32 along which the body 32 extends. In other words, the body 32 has an elongated shape surrounding the central axis XX, preferably being centered around this central axis XX. The central axis XX is, preferably, orthogonal to the plane in which the cover extends at the level of the skylight 1. This is however not limiting, since the central axis XX may not be orthogonal to the plane in which extends the cover at the level of the skylight 1. In fact, the body 32 forms a solid, or polyhedron, or prism, delimited by a cylindrical surface and by two open planes, forming the bases of the cylinder forming the body 32, which are strictly parallel, the planes being, respectively, constituted by the plane in which the glazing 2 extends on the one hand, and by the plane in which the through opening extends through the cover on the other hand.

Dans une variante (non représentée), le corps est un cylindre droit, c'est-à-dire que les plans sont perpendiculaires aux droites génératrices. Ceci n'est toutefois pas limitatif puisque, comme visible sur la figure 2 , dans un mode de réalisation privilégié, la base supérieure du cylindre formant le corps 32 est inclinée, typiquement d'un angle d'au plus 80°, par rapport à la base inférieure du cylindre formant le corps 32. In a variant (not shown), the body is a right cylinder, ie the planes are perpendicular to the generating lines. However, this is not limiting since, as visible on the figure 2 , in a preferred embodiment, the upper base of the cylinder forming the body 32 is inclined, typically at an angle of at most 80°, with respect to the lower base of the cylinder forming the body 32.

Ainsi, lorsque le corps 32 est un cylindre, il peut présenter diverses formes comme celle d'un parallélépipède illustré sur la figure 1 et sur la figure 2 , ou comme celle d'un cylindre de révolution (non représenté). Dans le cas du parallélépipède, une section transversale du corps 32, c'est-à-dire orthogonale aux droites génératrices et parallèle aux bases du cylindre, forme un rectangle, typiquement un carré. Dans le cas d'un cylindre de révolution (ou circulaire), une section transversale du corps forme un cercle.Thus, when the body 32 is a cylinder, it can have various shapes such as that of a parallelepiped illustrated in the figure 1 and on the figure 2 , or like that of a cylinder of revolution (not shown). In the case of the parallelepiped, a cross section of the body 32, that is to say orthogonal to the generating lines and parallel to the bases of the cylinder, forms a rectangle, typically a square. In the case of a cylinder of revolution (or circular), a cross section of the body forms a circle.

Dans une variante (non représentée), le corps est un cylindre formé par un seul panneau présentant deux bords en regard l'un de l'autre qui forment le premier bord et le deuxième bord. Le cylindre peut être formé par cintrage du panneau ou par pliage du panneau selon au moins un bord longitudinal, le bord longitudinal s'étendant selon une droite génératrice du corps.In a variant (not shown), the body is a cylinder formed by a single panel having two edges facing each other which form the first edge and the second edge. The cylinder can be formed by bending the panel or by folding the panel along at least one longitudinal edge, the longitudinal edge extending along a straight line generating the body.

Dans une autre variante illustrée sur la figure 1 , sur la figure 3 et sur la figure 4 , le corps 32 est un cylindre et la costière 3 comprend une pluralité de panneaux 301, 302, 303, 304 reliés deux à deux entre eux au moyen du dispositif de fixation, chaque panneau 301, 302, 303, 304 comprenant au moins deux bords 321, 322, un bord 321 d'un panneau 302 correspondant au premier bord 321 et un bord 322 d'un panneau 303 adjacent, en regard du premier bord 321, correspondant au deuxième bord 322. Le dispositif de fixation est alors prévu pour fixer un des au moins deux bords 321 de chaque panneau 301, 302, 303, 304 avec un des au moins deux bords 322 d'un panneau adjacent 301, 302, 303, 304. Dans ce cas, le dispositif de fixation comprend une pluralité de colles et une pluralité de rivets, une pluralité d'orifices 323 étant pratiqués dans les bords 321, 322 des panneaux correspondants 301, 302, 303, 304. De manière privilégiée, la costière 3 comprend quatre panneaux 301, 302, 303, 304 assemblés de sorte à ce que le corps 32 forme un parallélépipède, comme illustré sur la figure 1 , sur la figure 3 et sur la figure 4 . Alternativement, la costière comprend exactement deux panneaux, lesquels peuvent alors être cintrés, ou pliés, typiquement selon une pliure parallèle à l'axe central.In another variant illustrated on the figure 1 , on the picture 3 and on the figure 4 , the body 32 is a cylinder and the curb 3 comprises a plurality of panels 301, 302, 303, 304 connected two by two together by means of the fixing device, each panel 301, 302, 303, 304 comprising at least two edges 321, 322, an edge 321 of a panel 302 corresponding to the first edge 321 and an edge 322 of an adjacent panel 303 , facing the first edge 321, corresponding to the second edge 322. The fixing device is then provided to fix one of the at least two edges 321 of each panel 301, 302, 303, 304 with one of the at least two edges 322 of an adjacent panel 301, 302, 303, 304. In this case, the fixing device comprises a plurality of glues and a plurality of rivets, a plurality of orifices 323 being made in the edges 321, 322 of the corresponding panels 301, 302, 303, 304. Preferably, the curb 3 comprises four panels 301, 302, 303, 304 assembled so that the body 32 forms a parallelepiped, as illustrated in the figure 1 , on the picture 3 and on the figure 4 . Alternatively, the curb comprises exactly two panels, which can then be bent, or folded, typically along a fold parallel to the central axis.

Dans une variante (non représentée), le corps présente une forme tronconique évasée vers l'extérieur, c'est-à-dire dont la base du cône est formée par le vitrage et/ou la parclose. En d'autres termes, l'aire couvert par le vitrage est supérieure à la section transversale de l'ouverture traversante pratiquée à travers la couverture, la section transversale étant prise selon un plan de la couverture au niveau de l'ouverture traversante. Là encore, le corps peut être formé par un panneau ou par l'assemblage de plusieurs panneaux, de la même manière que ce qui a été décrit pour la variante dans laquelle le corps a une forme cylindrique.In a variant (not shown), the body has an outwardly flared frustoconical shape, that is to say the base of the cone of which is formed by the glazing and/or the glazing bead. In other words, the area covered by the glazing is greater than the cross section of the through opening made through the cover, the cross section being taken according to a plan of the cover at the level of the through opening. Here again, the body can be formed by a panel or by the assembly of several panels, in the same way as what has been described for the variant in which the body has a cylindrical shape.

Quelle que soit la forme du corps 32, dans une variante avantageuse, d'ailleurs illustrée sur la figure 1 , sur la figure 2 , sur la figure 3 , et plus précisément sur la figure 4 , chaque panneau 301, 302, 303, 304 comprend au moins deux pliures 3001, 3002. De cette manière, une partie de base 30, une partie de corps 32 et une partie de rebord 31, sont délimitées par les pliures 3001, 3002 sur chaque panneau 301, 302, 303, 304. Et ce sont les parties de corps 32 qui comprennent les au moins deux bords 321, 322. En outre, la partie de corps 32 est alors venue de matière avec la partie de base 30 et la partie de rebord 31. Whatever the shape of the body 32, in an advantageous variant, moreover illustrated in the figure 1 , on the figure 2 , on the picture 3 , and more specifically on the figure 4 , each panel 301, 302 , 303 , 304 comprises at least two folds 3001 , 3002 . each panel 301, 302, 303, 304. And it is the body parts 32 which include the at least two edges 321, 322. In addition, the body part 32 is then integral with the base part 30 and the rim portion 31.

En tout état de cause, au moins un panneau 301, 302, 303, 304 de la costière 3 est avantageusement formé à partir de tôle en acier, de préférence en acier galvanisé, dont l'épaisseur est comprise entre 1,0 et 5,0 millimètres, et vaut de préférence 2,0 millimètres, selon un procédé de fabrication détaillé ci-après.In any case, at least one panel 301, 302, 303, 304 of the curb 3 is advantageously formed from steel sheet, preferably galvanized steel, the thickness of which is between 1.0 and 5, 0 millimeters, and is preferably 2.0 millimeters, according to a manufacturing method detailed below.

En outre, le premier bord 321 et le deuxième bord 322 peuvent être des bords longitudinaux, comme visible sur la figure 1 , la figure 3 et la figure 4 , c'est-à-dire s'étendre selon une droite génératrice lorsque le corps 32 est un cylindre ou selon une droite joignant la base au sommet du cône lorsque le corps est tronconique. Ceci n'est toutefois pas limitatif, puisque, dans d'autres variantes (non représentées), le premier bord et/ou le deuxième bord peut s'étendre selon une droite inclinée par rapport à une droite génératrice lorsque le corps est un cylindre ou à une droite joignant la base au sommet du cône lorsque le corps est tronconique.In addition, the first edge 321 and the second edge 322 can be longitudinal edges, as visible on the figure 1 , the picture 3 and the figure 4 , that is to say extend along a generating line when the body 32 is a cylinder or along a line joining the base to the top of the cone when the body is frustoconical. However, this is not limiting, since, in other variants (not shown), the first edge and/or the second edge can extend along a straight line inclined with respect to a generating straight line when the body is a cylinder or to a straight line joining the base to the top of the cone when the body is frustoconical.

Dans une variante avantageuse illustrée sur la figure 1 , sur la figure 3 et sur la figure 4 , pour accommoder le recouvrement du premier bord 321 avec le deuxième bord 322 lorsque ces-derniers ne sont pas en regard suivant des plans parallèles entre eux, il est possible de prévoir que le corps 32 comprend une bride de fixation 321 formant le premier bord 321. Dans ce cas, les orifices 323 pour recevoir les rivets sont alors pratiqués dans la bride de fixation 321. De préférence, lorsque la costière 3 comprend quatre panneaux 301, 302, 303, 304, seules quatre brides de fixation 321 sont prévues, deux par panneau 302, 304 se faisant face, afin de limiter les coûts de fabrication de la costière 3 par rapport à la variante où chacun des quatre panneaux serait doté de sa propre bride de fixation.In an advantageous variant illustrated in the figure 1 , on the picture 3 and on the figure 4 , to accommodate the overlapping of the first edge 321 with the second edge 322 when the latter are not opposite along planes parallel to each other, it is possible to provide that the body 32 comprises a fixing flange 321 forming the first edge 321 In this case, the holes 323 to receive the rivets are then made in the fixing flange 321. Preferably, when the curb 3 comprises four panels 301, 302, 303, 304, only four fixing flanges 321 are provided, two per panel 302, 304 facing each other, in order to limit the manufacturing costs of the curb 3 compared to the variant where each of the four panels would be provided with its own fixing flange.

Dans une variante, particulièrement visible sur la figure 4 , la bride de fixation 321 ne s'étend pas le long de tout un bord d'une partie de corps 30 du panneau 302, 304, mais seulement sur une partie du bord de la partie de corps 30 du panneau 302, 304 afin de former le premier bord 321. Ceci libère de l'espace pour permettre de simplifier la fixation des parties de base 30 entre elles, et des parties de rebord 31 entre elles, typiquement par soudure.In a variant, particularly visible on the figure 4 , the fastening flange 321 does not extend along an entire edge of a body part 30 of the panel 302, 304, but only on a part of the edge of the body part 30 of the panel 302, 304 in order to form the first edge 321. This frees up space to make it possible to simplify the attachment of the base parts 30 to one another, and of the flange parts 31 to one another, typically by welding.

VitrageGlazing

En référence à la figure 1 , à la figure 2 et à la figure 7 , le vitrage 2 est positionné entre la parclose 4 et la costière 3, en étant maintenu sur le rebord 31 de la costière 3 par la parclose 4. Une surface supérieure 200 du vitrage 2 est alors en contact avec la parclose 4, tandis qu'une surface inférieure 201 du vitrage 2 est en contact avec la costière 3. With reference to the figure 1 , at the figure 2 and at the figure 7 , the glazing 2 is positioned between the glazing bead 4 and the curb 3, being held on the rim 31 of the curb 3 by the glazing bead 4. An upper surface 200 of the glazing 2 is then in contact with the glazing bead 4, while a lower surface 201 of the glazing 2 is in contact with the curb 3.

Le vitrage 2 comprend avantageusement du verre et, de préférence, est constitué de verre. De préférence, le verre est résistant au feu. En outre, au moins une partie du verre du vitrage 2 se dilate dans une première plage de température, puis se ramollit, et devient ductile, dans une deuxième plage de température, supérieure à la première plage de température. En outre, le verre est transparent pour autoriser le passage de lumière vers l'intérieur du bâtiment.Glazing 2 advantageously comprises glass and preferably consists of glass. Preferably, the glass is fire resistant. In addition, at least part of the glass of the glazing 2 expands in a first temperature range, then softens, and becomes ductile, in a second temperature range, higher than the first temperature range. In addition, the glass is transparent to allow the passage of light to the interior of the building.

Dans une variante, le vitrage 2 est un panneau en verre, dont la forme et les dimensions correspondent à la forme et aux dimensions de la costière 3. Sur la figure 1 , la figure 2 et la figure 7 , le vitrage 2 prend ainsi la forme d'un panneau rectangulaire posé à plat sur le rebord 31 de la costière 3. In a variant, the glazing 2 is a glass panel, the shape and dimensions of which correspond to the shape and dimensions of the curb 3. On the figure 1 , the figure 2 and the figure 7 , the glazing 2 thus takes the form of a rectangular panel placed flat on the rim 31 of the curb 3.

En tout état de cause, le vitrage 2 s'étend selon sensiblement selon un plan et présente ainsi une longueur, une largeur et une épaisseur, la longueur et la largeur étant très supérieures à l'épaisseur, l'épaisseur étant la dimension transversale à la surface supérieure 200 et à la surface inférieure 201 du vitrage 2. Lorsque le vitrage 2 a une forme circulaire, la longueur et la largeur sont les mêmes et forment le diamètre du vitrage 2. In any event, the glazing 2 extends substantially along a plane and thus has a length, a width and a thickness, the length and the width being much greater than the thickness, the thickness being the dimension transverse to the upper surface 200 and to the lower surface 201 of the glazing 2. When the glazing 2 has a circular shape, the length and the width are the same and form the diameter of the glazing 2.

Parclosebead

En référence à la figure 1 , à la figure 2 , à la figure 5 , à la figure 6 et à la figure 7 , la parclose 4 est prévue pour maintenir le vitrage 2 sur la costière 3 du lanterneau 1, et plus précisément sur le rebord 31 de la costière 3. With reference to the figure 1 , at the figure 2 , at the figure 5 , at the figure 6 and at the figure 7 , the glazing bead 4 is provided to hold the glazing 2 on the curb 3 of the skylight 1, and more precisely on the edge 31 of the curb 3.

Comme visible plus précisément sur la figure 5 et sur la figure 6 , la parclose 4 est une unique pièce monobloc formant un cadre délimitant une ouverture centrale 4000 et destiné à être positionné sur un pourtour du vitrage 2. De fait, la parclose 4 est fabriquée d'une seule pièce, en étant formée à partir d'une tôle en acier, c'est-à-dire à partir d'un produit sidérurgique en acier qui est plat, laminé soit à chaud, soit à froid, et dont la surface est généralement lisse ou présentant parfois des saillies. En outre, la parclose 4 forme la bordure délimitant la surface du vitrage 2, au niveau de son pourtour, c'est-à-dire de sa ligne externe. Grâce à son caractère monobloc en tôle d'acier, la parclose 4 peut se dilater de manière homogène lorsque le lanterneau 1 est soumis à de très hautes températures. De cette manière, la parclose 4 peut conserver une contrainte de maintien du vitrage 2 sur la costière 3 qui est homogène, ce qui limite le risque d'ouvertures entre la parclose 4 et le vitrage 2, laquelle pourrait amener les fumées et les flammes à s'échapper du lanterneau 1 en cas d'incendie se déclarant à l'intérieur du bâtiment.As visible more precisely on the figure 5 and on the figure 6 , the glazing bead 4 is a single one-piece piece forming a frame delimiting a central opening 4000 and intended to be positioned on a perimeter of the glazing 2. In fact, the glazing bead 4 is manufactured from a single piece, by being formed from a sheet of steel, that is to say from a steel product which is flat, rolled either hot or cold, and whose surface is generally smooth or sometimes with protrusions. In addition, the glazing bead 4 forms the border delimiting the surface of the glazing 2, at its periphery, that is to say its outer line. Thanks to its one-piece character made of sheet steel, the glazing bead 4 can expand evenly when the skylight 1 is subjected to very high temperatures. In this way, the glazing bead 4 can maintain a constraint for maintaining the glazing 2 on the curb 3 which is homogeneous, which limits the risk of openings between the glazing bead 4 and the glazing 2, which could cause smoke and flames to escape from skylight 1 in the event of a fire breaking out inside the building.

Dans une variante, l'acier est galvanisé, c'est-à-dire qu'il est revêtu d'une couche de zinc galvanisé afin de résister à la corrosion. De préférence, la parclose 4 est revêtue d'au moins une couche de peinture, typiquement quatre couches de peinture, afin d'améliorer sa résistance à la corrosion. Dans une variante avantageuse, la tôle en acier présente une épaisseur qui est comprise entre 1,0 et 5,0 millimètres, et vaut de préférence 2,0 millimètres.In a variant, the steel is galvanized, that is to say it is coated with a layer of galvanized zinc in order to resist corrosion. Preferably, the glazing bead 4 is coated with at least one coat of paint, typically four coats of paint, in order to improve its resistance to corrosion. In an advantageous variant, the steel sheet has a thickness which is between 1.0 and 5.0 millimeters, and is preferably 2.0 millimeters.

Dans une variante illustrée sur la figure 5 , la figure 6 et la figure 7 , la parclose 4 comprend une partie de maintien 41 et au moins une partie de rabat 42 s'étendant à partir de la partie de maintien 41. Avantageusement, la partie de maintien 41 est destinée à être positionnée sur une surface du vitrage 2, de préférence la surface supérieure 200 du vitrage 2, pour maintenir le vitrage 2 sur la costière 3. C'est pourquoi la partie de maintien 41 présente une planéité la plus exacte possible, c'est-à-dire qu'elle s'étend dans un plan sans en dévier, et ce afin de favoriser une dilatation thermique de la partie de maintien 41 dans ce plan exactement, et de conserver une contrainte de maintien uniforme sur toute la surface supérieure 200 du vitrage 2, quelle que soit la température atteinte par le lanterneau 1. De même, la partie de rabat 42 est avantageusement destinée à être positionnée en regard d'un bord du vitrage 2, typiquement le bord 202 reliant la surface inférieure 201 à la surface supérieure 200 du vitrage 2. La partie de rabat 42, tout comme la deuxième portion 312 de la section transversale du rebord 31 de la costière 3 en regard de laquelle une portion de la partie de rabat 42 s'étend, permet de faciliter l'évacuation de fluide, typiquement d'eau de pluie, venant à s'écouler sur la surface supérieure 200 du vitrage 2 et/ou sur la partie de maintien 41 de la parclose 4. Ceci permet de garantir que ce fluide puisse retomber sur la couverture au niveau d'une zone éloignée du matériau d'isolation, empêchant que ce-dernier ne se détériore et endommage ainsi le lanterneau 1. In a variant illustrated on the figure 5 , the figure 6 and the figure 7 , the glazing bead 4 comprises a holding part 41 and at least one flap part 42 extending from the holding part 41. Advantageously, the holding part 41 is intended to be positioned on a surface of the glazing 2, preferably the upper surface 200 of the glazing 2, to hold the glazing 2 on the curb 3. This is why the holding part 41 has the most exact possible flatness, that is to say that it extends in a plane without deviating from it, in order to promote thermal expansion of the holding part 41 in this plane exactly, and to maintain a uniform holding stress over the entire upper surface 200 of the glazing 2, whatever the temperature reached by the skylight 1. Similarly, the flap part 42 is advantageously intended to be positioned opposite an edge of the glazing 2, typically the edge 202 connecting the lower surface 201 to the upper surface 200 of the glazing 2. The flap part 42, just like the second portion 312 of the cross section of the rim 31 of the curb 3 opposite which a portion of the flap part 42 extends, makes it possible to facilitate the evacuation of fluid, typically rainwater , coming to flow on the upper surface 200 of the glazing 2 and/or on the retaining part 41 of the glazing bead 4 . insulation, preventing the latter from deteriorating and thus damaging the skylight 1.

Dans une variante illustrée sur la figure 6 , la partie de maintien 41 forme un cadre rectangulaire, typiquement carrée. Ceci n'est toutefois pas limitatif puisque la partie de maintien peut prendre n'importe quelle forme qui épouse le pourtour du vitrage, typiquement une forme circulaire. Lorsque la partie de maintien 41 est un cadre rectangulaire, il présente quatre côtés et la parclose 4 comprend alors quatre parties de rabat 42, chaque partie de rabat 42 s'étendant à partir de chacun des quatre côtés de la partie de maintien 41. Lorsque la partie de maintien est un cadre circulaire, il présente une périphérie externe, la parclose comprenant alors au moins une partie de rabat s'étendant à partir de la périphérie externe.In a variant illustrated on the figure 6 , the holding part 41 forms a rectangular frame, typically square. However, this is not limiting since the holding part can take any shape that matches the periphery of the glazing, typically a circular shape. When the holding part 41 is a rectangular frame, it has four sides and the glazing bead 4 then comprises four flap parts 42, each flap part 42 extending from each of the four sides of the holding part 41. When the holding part is a circular frame, it has an outer periphery, the glazing bead then comprising at least one flap part extending from the outer periphery.

Dans une variante, la partie de rabat et la partie de maintien sont formées par emboutissage puis poinçonnage de la tôle en acier de sorte à former le cadre monobloc.In a variant, the flap part and the holding part are formed by stamping then punching the steel sheet so as to form the one-piece frame.

Dans une autre variante, illustrée sur la figure 5 et la figure 6 , au moins une partie de rabat 42 est formée par pliure de la tôle en acier.In another variant, illustrated in the figure 5 and the figure 6 , at least a flap portion 42 is formed by bending the steel sheet.

Lorsque la partie de maintien est un cadre circulaire, la parclose peut alors être formée par cintrage de la tôle en acier. Plus précisément, la tôle est d'abord pliée de sorte à former un élément rectiligne présentant une section transversale en forme de L, une branche du L étant destinée à former la partie de maintien, l'autre branche du L étant destinée à former la partie de rabat. Puis cet élément rectiligne est cintré de sorte à ce que ses deux extrémités se trouvent en regard. Enfin, les deux extrémités sont fixées bord à bord, de préférence par soudure, de sorte à obtenir le cadre circulaire.When the retaining part is a circular frame, the glazing bead can then be formed by bending the steel sheet. More specifically, the sheet is first bent so as to form a rectilinear element having an L-shaped cross-section, one branch of the L being intended to form the holding part, the other branch of the L being intended to form the flap part. Then this rectilinear element is bent so that its two ends face each other. Finally, the two ends are fixed edge to edge, preferably by welding, so as to obtain the circular frame.

Lorsque la partie de maintien 41 est un cadre rectangulaire, les quatre parties de rabat 42 sont pliées à partir de la partie de maintien 41, comme visible sur la figure 6 . Puis, comme visible sur la figure 5 , les parties de rabat 42 sont fixées deux à deux, typiquement en étant reliées par soudure.When the holding part 41 is a rectangular frame, the four flap parts 42 are folded from the holding part 41, as seen in the figure 6 . Then, as seen in the figure 5 , the flap parts 42 are fixed two by two, typically by being connected by welding.

En tout état de cause, chaque partie de rabat 42 comprend avantageusement un bord principal 421 qui est opposé à la partie de maintien 41, et deux bords latéraux 422, 423 reliant le bord principal 421 à la partie de maintien 41. Lorsque le cadre est circulaire, les deux bords latéraux sont fixés l'un à l'autre. Lorsque le cadre est rectangulaire ou présente toute forme polygonale non circulaire, les parties de rabat 42 sont reliées deux à deux par leurs bords latéraux 422, 423 respectifs. A chaque fois, une fois les bords latéraux reliés entre eux, le bord principal demeure libre.In any case, each flap part 42 advantageously comprises a main edge 421 which is opposite to the holding part 41, and two side edges 422, 423 connecting the main edge 421 to the holding part 41. When the frame is circular, the two side edges are fixed to each other. When the frame is rectangular or has any non-circular polygonal shape, the flap parts 42 are connected two by two by their respective side edges 422, 423 . Each time, once the side edges are connected together, the main edge remains free.

Lorsque les bords latéraux sont reliés par soudure, un cordon de soudure est prévu au niveau d'une surface interne de la jonction entre les bords latéraux et/ou un autre cordon de soudure est prévu au niveau d'une surface externe de la jonction entre les bords latéraux.When the side edges are joined by welding, a weld bead is provided at an inner surface of the joint between the side edges and/or another weld bead is provided at an outer surface of the joint between the side edges.

Bien entendu, ceci n'est pas limitatif, puisque d'autres moyens de fixation des bords latéraux entre eux sont envisageables, typiquement un rivet et une colle comme décrit en référence au corps 32 de la costière 3. Of course, this is not limiting, since other means for fixing the side edges together are possible, typically a rivet and glue as described with reference to the body 32 of the curb 3.

Système de fixation de la parclose à la costièreFixing system of the glazing bead to the curb

En référence à la figure 1 , à la figure 2 , et plus particulièrement à la figure 7 , le lanterneau 1 comprend un système de fixation prévu pour fixer la parclose 4 à la costière 3, et ainsi maintenir le vitrage 2 en position entre la parclose 4 et la costière 3, sans fuite possible de flammes et/ou de fumées, même en cas de très hautes températures, typiquement lorsqu'un incendie se déclare à l'intérieur du bâtiment.With reference to the figure 1 , at the figure 2 , and more particularly to the figure 7 , the skylight 1 comprises a fixing system designed to fix the glazing bead 4 to the curb 3, and thus maintain the glazing 2 in position between the glazing bead 4 and the curb 3, without any possible escape of flames and/or smoke, even in very high temperatures, typically when a fire breaks out inside the building.

Ce système de fixation prévoit la coopération d'un élément fileté 61 avec un organe de fixation 7, lequel comprend un filetage prévu pour coopérer avec l'élément fileté 61. This fixing system provides for the cooperation of a threaded element 61 with a fixing member 7, which comprises a thread provided to cooperate with the threaded element 61.

Dans une variante préférée, illustrée sur la figure 7 , l'élément fileté 61 appartient à un organe 6 qui est prévu pour traverser la parclose 4 en vue de coopérer avec l'organe de fixation 7, lequel est prévu pour être fixé à la costière 3. Dans une variante alternative (non représentée), l'élément fileté appartient à un organe qui est prévu pour traverser la costière en vue de coopérer avec l'organe de fixation, lequel est prévu pour être fixé à la parclose.In a preferred variant, illustrated in the figure 7 , the threaded element 61 belongs to a member 6 which is provided to pass through the glazing bead 4 in order to cooperate with the fixing member 7, which is provided to be fixed to the curb 3. In an alternative variant (not shown) , the threaded element belongs to a member which is intended to pass through the curb in order to cooperate with the fixing member, which is intended to be fixed to the glazing bead.

Au moins une entretoise 6 est agencée entre la parclose 4 et la costière 3, et forme l'organe 6 ayant l'élément fileté 61. De préférence, comme visible sur la figure 1 , une pluralité d'entretoises 6 sont agencées entre la parclose 4 et la costière 3, en étant réparties sur le pourtour du rebord 31 de la costière 3. At least one spacer 6 is arranged between the glazing bead 4 and the curb 3, and forms the member 6 having the threaded element 61. Preferably, as visible on the figure 1 , a plurality of spacers 6 are arranged between the glazing bead 4 and the curb 3, being distributed around the periphery of the rim 31 of the curb 3.

L'entretoise 6 est configurée pour limiter les efforts appliqués au vitrage 2 par la parclose 4 et/ou par la costière 3. Plus précisément, l'entretoise 6 présente des dimensions, et de préférence une hauteur, qui sont calibrées de sorte à maîtriser les efforts appliqués au vitrage 2 par la parclose 4 et/ou par la costière 3 lors de la mise en prise de l'élément fileté 61 avec l'organe de fixation 7. De cette manière, le maintien du vitrage 2 sur la costière 3 par la parclose 4 est réalisé au moyen de contraintes dont l'intensité est contrôlée avec précision, ce qui permet de contenir la dilatation thermique du vitrage 2, tout en évitant son fluage, à chaque fois en vue d'éviter l'apparition d'ouvertures entre la costière 3 et le vitrage 2 et/ou entre le vitrage 2 et la parclose 4, lorsque le lanterneau 1 atteint des températures très importantes. En outre, la contrainte appliquée au vitrage 2 par la parclose 4 et/ou par la costière 3 est contrôlée de sorte à garantir l'étanchéité au fluide, typiquement à l'eau de pluie, du lanterneau 1. En d'autres termes, la contrainte est contrôlée de manière à être suffisamment forte pour garantir le maintien du vitrage 2 sur la costière 3 (et ainsi l'étanchéité du lanterneau 1), notamment lors d'un éventuel fluage à haute température, mais suffisamment faible pour que le vitrage 2 puisse se dilater à haute température sans se briser à cause de cette déformation thermique.The spacer 6 is configured to limit the forces applied to the glazing 2 by the bead 4 and/or by the curb 3. More precisely, the spacer 6 has dimensions, and preferably a height, which are calibrated so as to control the forces applied to the glazing 2 by the glazing bead 4 and/or by the curb 3 when the threaded element 61 is engaged with the fixing member 7. In this way, the maintenance of the glazing 2 on the curb 3 by the glazing bead 4 is produced by means of stresses whose intensity is precisely controlled, which makes it possible to contain the thermal expansion of the glazing 2, while avoiding its creep, each time with a view to avoiding the appearance of openings between curb 3 and glazing 2 and/or between glazing 2 and glazing bead 4, when skylight 1 reaches very high temperatures. In addition, the stress applied to the glazing 2 by the glazing bead 4 and/or by the curb 3 is controlled so as to guarantee fluid-tightness, typically rainwater, of the skylight 1. In other words, the constraint is controlled so as to be strong enough to guarantee the maintenance of the glazing 2 on the curb 3 (and thus the tightness of the skylight 1 ), in particular during a possible creep at high temperature, but low enough for the glazing 2 to be able to expand at high temperature without breaking due to this thermal deformation.

En outre, l'entretoise 6 présente une surface externe 600 en contact avec une surface interne de la parclose 4, plus précisément avec une surface interne de la partie de maintien 41 de la parclose 4, et une surface interne 601 en contact avec une surface externe de la costière 3, plus précisément avec une surface externe du rebord 31 de la costière 3. De préférence, chacun de la surface externe 600 et de la surface interne 601 de l'entretoise 6 présente une planéité la plus précise possible, afin de garantir le parallélisme de la surface interne de la partie de maintien 41 de la parclose 4 et de la surface externe du rebord 31 de la costière 3. Ceci garantit que la dilatation thermique du vitrage 2 puisse se dérouler de manière homogène, de préférence uniquement dans le plan d'extension du vitrage 2, c'est-à-dire parallèlement à la surface inférieure 201 et à la surface supérieure 200 du vitrage 2. De cette manière, lors de la dilatation thermique du vitrage 2 à hautes températures, les contraintes exercées par le vitrage 2 sur la parclose 4 et/ou sur la costière 4 sont réduites au minimum dans une direction transversale au plan d'extension du vitrage 2. In addition, the spacer 6 has an outer surface 600 in contact with an inner surface of the bead 4, more precisely with an inner surface of the retaining part 41 of the bead 4, and an inner surface 601 in contact with a surface outer surface of the curb 3, more precisely with an outer surface of the rim 31 of the curb 3. Preferably, each of the outer surface 600 and the inner surface 601 of the spacer 6 has the most precise flatness possible, in order to guarantee the parallelism of the internal surface of the retaining part 41 of the glazing bead 4 and of the external surface of the rim 31 of the curb 3. This guarantees that the thermal expansion of the glazing 2 can take place in a homogeneous manner, preferably only in the extension plane of the glazing 2, that is to say parallel to the lower surface 201 and to the upper surface 200 of the glazing 2. In this way, during the thermal expansion of the glazing 2 at high temperatures, the stresses exerted by the glazing 2 on the glazing bead 4 and/or on the curb 4 are reduced to a minimum in a direction transverse to the plane of extension of the glazing 2.

Lorsqu'une pluralité d'entretoises 6 est prévue, toutes les surfaces externes 600 des entretoises 6 sont parallèles les unes aux autres afin que la parclose 4 exerce une contrainte uniforme sur le vitrage 2 une fois fixée sur la costière 3. When a plurality of spacers 6 is provided, all the outer surfaces 600 of the spacers 6 are parallel to each other so that the glazing bead 4 exerts a uniform stress on the glazing 2 once fixed on the curb 3.

Dans une variante, l'entretoise comprend de l'acier inoxydable, voire est constituée d'acier inoxydable, dont les propriétés mécaniques sont adaptées au contrôle des efforts appliqués au vitrage par la parclose et/ou par la costière.In one variant, the spacer comprises stainless steel, or even consists of stainless steel, the mechanical properties of which are suitable for controlling the forces applied to the glazing by the glazing bead and/or by the curb.

Comme illustré sur la figure 7 , l'entretoise 6 comprend avantageusement l'élément fileté 61 destiné à coopérer avec l'organe de fixation 7. As illustrated on the figure 7 , the spacer 6 advantageously comprises the threaded element 61 intended to cooperate with the fixing member 7.

Plus précisément, l'entretoise 6 comprend une section de corps 60 s'étendant entre la parclose 4 et la costière 3, et un téton 61 faisant saillie d'une extrémité de la section de corps 60, le téton 61 étant destiné à traverser l'une parmi la parclose 3 et la costière 4. Une section transversale de la section de corps 60 est avantageusement supérieure à une section transversale du téton 61, la section transversale étant prise orthogonalement à un axe principal d'extension Y-Y de l'entretoise 6. De préférence, c'est alors une surface externe du téton 61 qui est fileté, la surface externe étant cette fois définie radialement par rapport à l'axe principal d'extension Y-Y, l'organe de fixation 7 étant alors taraudé pour coopérer avec le téton 61. De manière avantageuse, l'extrémité inférieure du téton 61, laquelle n'est pas filetée, est toutefois chanfreinée, de sorte à favoriser la coopération avec l'organe de fixation 7. More specifically, the spacer 6 comprises a body section 60 extending between the glazing bead 4 and the upstand 3, and a stud 61 projecting from one end of the body section 60, the stud 61 being intended to pass through the one of the glazing bead 3 and the curb 4. A cross section of the body section 60 is advantageously greater than a cross section of the pin 61, the cross section being taken orthogonal to a main axis of extension YY of the spacer 6 Preferably , it is then an outer surface of the pin 61 which is threaded, the outer surface this time being defined radially with respect to the main axis of extension YY, the fixing member 7 then being threaded to cooperate with the stud 61. Advantageously, the lower end of the stud 61, which is not threaded, is however chamfered, so as to promote cooperation with the fixing member 7.

Dans une variante illustrée sur la figure 7 , la section de corps 60 comprend une portion cylindrique, de préférence cylindrique droite, voire cylindrique de révolution. Plus précisément, la section de corps 60 comprend une portion qui est un cylindre, selon les mêmes propriétés que celles décrites en référence au corps 32 de la costière 3. In a variant illustrated on the figure 7 , the body section 60 comprises a cylindrical portion, preferably straight cylindrical, or even cylindrical of revolution. More specifically, the body section 60 comprises a portion which is a cylinder, according to the same properties as those described with reference to the body 32 of the curb 3.

En outre, un orifice taraudé 62 est avantageusement ménagé dans la section de corps 60. En effet, le système de fixation comprend de préférence une vis 8 adaptée pour coopérer avec l'orifice taraudé 62, et ainsi fixer l'entretoise 6 à l'une de la parclose 4 et de la costière 3, tandis que l'organe de fixation 7 est fixé sur l'autre de la costière 3 et de la parclose 4. En définitive, au lieu de prévoir une vis traversant l'un parmi la costière 4 et la parclose 3 pour coopérer avec un organe de fixation 7 fixé sur l'autre de la parclose 3 et de la costière 4, la vis 8 coopère d'abord avec l'entretoise 6, laquelle coopère ensuite avec l'organe de fixation 7. Ainsi, les efforts appliqués au vitrage 2 par la parclose 4 et/ou par la costière 3 sont mieux contrôlés, puisqu'il n'existe pas de risque que la parclose 4 et/ou la costière 3 ne se déforme lors du vissage de l'entretoise 6 dans l'organe de fixation 7 et/ou lors du vissage de la vis 8 dans l'entretoise 6. De préférence, le système de fixation comprend une rondelle 9 prévue pour être positionnée entre la vis 8 et l'une parmi la parclose 4 et la costière 3 à travers laquelle la vis 8 s'étend pour fixer l'entretoise 6, et ce afin de limiter les efforts appliqués par la vis 8 sur la parclose 4 ou la costière 3. Alternativement à la vis 8, d'autres types d'élément de fixation peuvent être prévus, comme un clou ou une cheville, l'orifice 62 n'étant pas alors nécessairement taraudé. En tout état de cause, des orifices 400 peuvent être prévus dans la parclose 4, de préférence dans la partie de maintien 41 comme visible sur la figure 5 et sur la figure 6 , pour qu'elle puisse être traversée par la vis 8, le clou, la cheville, etc.In addition, a threaded hole 62 is advantageously made in the body section 60. Indeed, the fixing system preferably comprises a screw 8 adapted to cooperate with the threaded hole 62, and thus fix the spacer 6 to the one of the glazing bead 4 and of the curb 3, while the fastening member 7 is fixed to the other of the curb 3 and of the glazing bead 4. Ultimately, instead of providing a screw passing through one of the curb 4 and glazing bead 3 to cooperate with a fastening member 7 fixed to the other of glazing bead 3 and of curb 4, screw 8 first cooperates with spacer 6, which then cooperates with the fixing 7. Thus, the forces applied to the glazing 2 by the glazing bead 4 and/or by the curb 3 are better controlled, since there is no risk that the glazing bead 4 and/or the curb 3 will deform during the screwing of the spacer 6 into the fixing member 7 and/or when screwing the screw 8 into the spacer 6. Preferably, the fixing system comprises a washer 9 provided to be positioned between the screw 8 and the one among the glazing bead 4 and the curb 3 through which the screw 8 extends to fix the spacer 6, and this in order to limit the forces applied by the screw 8 on the glazing bead 4 or the curb 3. Alternatively to the screw 8, other types of fastening element can be provided, such as a nail or a dowel, the orifice 62 then not necessarily being threaded. In any case, orifices 400 can be provided in the glazing bead 4, preferably in the holding part 41 as visible on the figure 5 and on the figure 6 , so that it can be crossed by the screw 8, the nail, the dowel, etc.

Dans une autre variante (non représentée), le système de fixation comprend une tige filetée faisant saillie de la section de corps de l'entretoise et prévue pour traverser l'une de la parclose et de la costière pour y fixer l'entretoise. Pour ce faire, la tige filetée peut coopérer avec un écrou rapporté sur la tige et serré sur l'une de la parclose et de la costière. La tige filetée peut être rapportée et fixée sur la section de corps ou être venue de matière avec la section de corps.In another variant (not shown), the fixing system comprises a threaded rod protruding from the body section of the spacer and designed to pass through one of the bead and the curb in order to fix the spacer there. To do this, the threaded rod can cooperate with a nut attached to the rod and tightened on one of the glazing bead and the curb. The threaded rod can be attached and fixed to the body section or be integral with the body section.

Dans une variante illustrée sur la figure 7 , l'orifice taraudé 62 s'étend selon la hauteur de la portion cylindrique de la section de corps 60. En outre, l'orifice taraudé 62 est borgne en débouchant au niveau de la surface supérieure 600 de la section de corps 60, sans être débouchant au niveau de l'extrémité inférieure du téton 61, ni même de la section de corps 60, au niveau de la jonction entre la section de corps 60 et le téton 61. La profondeur de l'orifice taraudé 62 ménagé dans la section de corps 60 peut être ajustée en fonction du contrôle souhaité dans les contraintes appliquées au vitrage 2, mais aussi en fonction du coût de fabrication.In a variant illustrated on the figure 7 , the threaded orifice 62 extends along the height of the cylindrical portion of the body section 60. In addition, the threaded orifice 62 is blind, emerging at the level of the upper surface 600 of the body section 60, without be opening at the level of the lower end of the stud 61, or even of the body section 60, at the level of the junction between the body section 60 and the stud 61. The depth of the threaded orifice 62 formed in the section of body 60 can be adjusted according to the desired control in the constraints applied to the glazing 2, but also according to the manufacturing cost.

De préférence, comme illustré sur la figure 7 , l'organe de fixation 7 est fixé à la costière 3, et la vis 8 fixe l'entretoise 6 à la parclose 4. Preferably, as illustrated in the figure 7 , the fixing member 7 is fixed to the curb 3, and the screw 8 fixes the spacer 6 to the glazing bead 4.

Dans une variante illustrée sur la figure 7 , une section transversale de la section de corps 60 est supérieure à une section transversale de l'organe de fixation 7. Ceci permet de garantir l'étanchéité au niveau de la jonction entre l'entretoise 6 et de l'organe de fixation 7, au cas où du fluide s'infiltrerait entre la parclose 4 et le vitrage 2. De cette manière, le fluide ne risque pas de pénétrer au sein de l'organe de fixation 7 et de s'écouler sur le matériau d'isolation, mais poursuit plutôt sa route vers la deuxième portion 312 de la section transversale du rebord 31 de la costière 3, pour se déverser sur la couverture dans une zone distante du matériau d'isolation.In a variant illustrated on the figure 7 , a cross section of the body section 60 is greater than a cross section of the fixing member 7. This makes it possible to guarantee sealing at the junction between the spacer 6 and the fixing member 7, in the event that fluid infiltrates between the glazing bead 4 and the glazing 2. In this way, the fluid does not risk penetrating within the fixing member 7 and flowing onto the insulation material, but rather continues its route towards the second portion 312 of the cross section of the rim 31 of the curb 3, to flow onto the cover in a zone remote from the insulation material.

De manière privilégiée, l'organe de fixation est un rivet 7, lequel est en outre prévu pour être riveté à la costière 3. Ceci permet notamment de mieux garantir l'étanchéité de la coopération entre l'élément fileté 61 et l'organe de fixation 7, au cas où du fluide s'infiltrerait entre la parclose 4 et le vitrage 2. Preferably, the fixing member is a rivet 7, which is also provided to be riveted to the curb 3. This makes it possible in particular to better guarantee the tightness of the cooperation between the threaded element 61 and the fixing 7, in case fluid infiltrates between the glazing bead 4 and the glazing 2.

Le rivet 7 comprend classiquement une tête percée d'une ouverture traversante, un tirant s'étendant à l'intérieur du rivet 7 pour permettre le rivetage, et une portion de faiblesse, laquelle est destinée à se déformer par traction du rivet 7 à travers la tête.The rivet 7 conventionally comprises a head pierced with a through opening, a tie rod extending inside the rivet 7 to allow riveting, and a portion of weakness, which is intended to deform by pulling the rivet 7 through the head.

En outre, le rivet 7 comprend avantageusement une portion de cylindre, laquelle est destinée à traverser la costière 3, de préférence en étant entouré par la tête et par la portion de faiblesse. Plus précisément, le rivet 7 comprend une portion qui est un cylindre, selon les mêmes propriétés que celles décrites en référence au corps 32 de la costière 3. De préférence, cette portion de cylindre n'est pas de révolution, voire est hexagonale, comme illustré sur la figure 7 . De cette manière, le risque que le rivet 7 tourner autour de son axe principal lors du vissage de l'élément fileté 61 sur le rivet 7, est limité. De la même manière, un orifice traversant 313 est ménagé dans la costière 3, et plus précisément à travers le rebord 31 de la costière 3, pour recevoir le rivet 7, et plus précisément la portion de cylindre du rivet 7. L'orifice traversant 313 présente avantageusement la même section transversale que celle de la portion de cylindre du rivet 7, de sorte à pouvoir l'accueillir et faciliter le vissage et/ou le dévissage de l'élément fileté 61 sur le rivet 7, c'est-à-dire que l'orifice traversant 313 est cylindrique, de préférence en présentant une section transversale qui n'est pas de révolution, voire qui est hexagonale.In addition, the rivet 7 advantageously comprises a cylinder portion, which is intended to pass through the curb 3, preferably being surrounded by the head and by the weak portion. More precisely, the rivet 7 comprises a portion which is a cylinder, according to the same properties as those described with reference to the body 32 of the curb 3. Preferably, this cylinder portion is not of revolution, or even is hexagonal, as illustrated on the figure 7 . In this way, the risk of the rivet 7 rotating around its main axis when screwing the threaded element 61 onto the rivet 7 is limited. In the same way, a through hole 313 is formed in the curb 3, and more precisely through the rim 31 of the curb 3, to receive the rivet 7, and more precisely the cylinder portion of the rivet 7. The through hole 313 advantageously has the same cross-section as that of the cylinder portion of the rivet 7, so as to be able to accommodate it and facilitate the screwing and/or unscrewing of the threaded element 61 on the rivet 7, i.e. to say that the through orifice 313 is cylindrical, preferably having a cross section which is not of revolution, or even which is hexagonal.

Dans une variante, un orifice borgne, de préférence taraudé pour coopérer avec l'élément fileté 61, est ménagé dans la portion de cylindre du rivet 7. L'orifice borgne est en outre destiné à être en regard de la parclose 4 lorsque le rivet 7 est riveté à la costière 3. Plus précisément, l'orifice taraudé borgne débouche sur la base de la portion cylindrique du rivet 7 qui est en regard de la parclose 4, sans déboucher sur la base de la portion cylindrique du rivet 7 qui est en regard du matériau isolant, de sorte à ce que, en cas d'infiltration de fluide au sein du rivet 7, le fluide ne s'écoule pas sur le matériau isolant. De préférence, la portion taraudée du rivet 7 n'est pas déformée lorsque le rivet 7 est riveté sur la costière 3, c'est-à-dire que la portion taraudée du rivet 7 est distincte de la portion de faiblesse du rivet 7. Alternatively, a blind hole, preferably tapped to cooperate with the threaded element 61, is made in the cylinder portion of the rivet 7. The blind hole is also intended to face the bead 4 when the rivet 7 is riveted to the curb 3. More precisely, the blind tapped hole opens onto the base of the cylindrical portion of the rivet 7 which faces the glazing bead 4, without opening onto the base of the cylindrical portion of the rivet 7 which is opposite the insulating material, so that, in the event of infiltration of fluid within the rivet 7, the fluid does not flow onto the insulating material. Preferably, the threaded portion of the rivet 7 is not deformed when the rivet 7 is riveted to the curb 3, that is to say that the threaded portion of the rivet 7 is distinct from the weak portion of the rivet 7.

Procédé de fabricationManufacturing process

En référence à la figure 8 , un procédé de fabrication du lanterneau 1 illustré sur la figure 1 et sur la figure 2 comprend avantageusement les étapes successives décrites ci-après.With reference to the figure 8 , a method of manufacturing the skylight 1 illustrated in the figure 1 and on the picture 2 advantageously comprises the successive steps described below.

Une tôle en acier est découpée E1, de sorte à former la parclose 4 d'une part, comme illustrée sur la figure 6 , et les panneaux 301, 302, 303, 304 de la costière 3 d'autre part. La découpe E1 peut être réalisé par tout moyen de découpe adaptée, tel que par emboutissage, poinçonnage ou même au laser, ce-dernier permettant notamment de limiter les déformations de la tôle.A steel sheet is cut E1, so as to form the glazing bead 4 on the one hand, as illustrated in the figure 6 , and the panels 301, 302, 303, 304 of the curb 3 on the other hand. The cutout E1 can be made by any suitable cutting means, such as by stamping, punching or even by laser, the latter notably making it possible to limit the deformations of the sheet.

Des orifices de fixation 300, 323, 313, 400 sont pratiqués E2 dans la parclose 4 comme dans les panneaux 301, 302, 303, 304 de la costière 3. Dans la costière 3, les orifices de fixation 300, 323, 313 sont pratiqués tant dans la partie de base 30 de chaque panneau 301, 302, 303, 304, pour la fixation à la couverture, que dans les brides de fixation 321 et les bords 322 de la partie de corps 32 de chaque panneau 301, 302, 303, 304, pour la fixation par rivetage et collage, et que dans la partie de rebord 31 de chaque panneau 301, 302, 303, 304, pour le rivetage des rivets 7 taraudés. Dans la parclose 3, les orifices de fixations 400 sont ménagés dans la partie de maintien 41 pour la fixation des entretoises 6 à la parclose 4. Comme pour la découpe E1, la pratique E2 des orifices de fixation 300, 323, 313, 400 peut être réalisée par emboutissage, poinçonnage ou même au laser, ce-dernier permettant notamment de limiter les déformations de la tôle.Fixing holes 300, 323, 313, 400 are made E2 in the glazing bead 4 as in the panels 301, 302, 303, 304 of the curb 3. In the curb 3, the fixing holes 300, 323, 313 are made both in the base part 30 of each panel 301, 302, 303, 304, for fixing to the cover, and in the fixing flanges 321 and the edges 322 of the body part 32 of each panel 301, 302, 303 , 304, for fixing by riveting and gluing, and only in the rim portion 31 of each panel 301, 302, 303, 304, for riveting the rivets 7 tapped. In the glazing bead 3, the fixing holes 400 are made in the retaining part 41 for fixing the spacers 6 to the glazing bead 4. As for the cutout E1, the practice E2 of the fixing holes 300, 323, 313, 400 can be made by stamping, punching or even laser, the latter allowing in particular to limit the deformations of the sheet.

Alternativement, le corps de la costière pourrait ne comprendre qu'un seul panneau qui, une fois les orifices de fixation pratiqués, serait alors cintré et/ou plié de sorte à faire correspondre un premier rebord et un deuxième rebord.Alternatively, the body of the curb could comprise only a single panel which, once the fixing holes have been made, would then be bent and/or folded so as to match a first rim and a second rim.

La partie de base 30 et la partie de rebord 31 de chaque panneau 301, 302, 303, 304 sont formées par pliure E3 des panneaux 301, 302, 303, 304, de sorte à délimiter la partie de corps 32. The base part 30 and the rim part 31 of each panel 301, 302, 303, 304 are formed by folding E3 of the panels 301, 302, 303, 304, so as to delimit the body part 32.

La partie de maintien 41 et les parties de rabat 42 de la parclose sont formées par pliure E3 ou par emboutissage, lequel éventuellement complétée par un poinçonnage si le cadre de la parclose 4, avec son ouverture centrale 4000 pour autoriser le passage de la lumière à travers le vitrage 2, n'a pas précédemment été découpée dans la tôle. En cas de pliure, les bords latéraux 422, 423 des parties de rabat 42 sont fixés entre eux, de préférence par soudure, à l'aide d'un cordon interne et/ou externe au niveau de la jonction entre les bords latéraux 422, 423. The retaining part 41 and the flap parts 42 of the glazing bead are formed by folding E3 or by stamping, which may be supplemented by punching if the frame of the glazing bead 4, with its central opening 4000 to allow the passage of light to through the glazing 2, has not previously been cut in the sheet. In the event of folding, the side edges 422, 423 of the flap parts 42 are fixed together, preferably by welding, using an internal and/or external cord at the junction between the side edges 422, 423.

Les parties de rebord ou le rebord 31 sont/est posé(es) E4 sur un bâti plat (non représenté), afin de garantir la planéité du rebord 31 la plus exacte possible, pour ensuite recevoir le vitrage 2. La surface du bâti sur laquelle le rebord 31 est posé s'étend donc dans un plan sans en dévier, le plan s'étendant de préférence selon l'inclinaison du vitrage 2 recherché dans le lanterneau 1. The rim parts or the rim 31 are/are placed E4 on a flat frame (not shown), in order to guarantee the flatness of the rim 31 as exact as possible, in order to then receive the glazing 2. The surface of the frame on which the rim 31 is placed therefore extends in a plane without deviating from it, the plane preferably extending according to the inclination of the glazing 2 sought in the skylight 1.

Le premier bord 321 du corps 32 de la costière 3 est collé E5 sur le deuxième bord 322 du corps 32 de la costière 3. De préférence, le collage E5 est mis en œuvre par dépôt de portions de colle distinctes qui sont réparties le long du deuxième bord 322 et/ou du premier bord 321. De manière privilégiée, les portions de colle sont déposées sur le bord 322 des panneaux 301, 302, 303, 304 en regard de la bride de fixation 321, pour que, au moment d'approcher et de mettre la bride de fixation 321 en pression sur le deuxième bord 322, la colle s'écrase vers l'extérieur. De cette manière, si la jonction entre la bride de fixation 321 et le deuxième bord 322 est amenée à fluer par dilation thermique, le fluage puisse s'ouvrir vers l'extérieur afin de garantir l'étanchéité du lanterneau 1. The first edge 321 of the body 32 of the curb 3 is glued E5 to the second edge 322 of the body 32 of the curb 3. Preferably, the bonding E5 is implemented by depositing separate portions of glue which are distributed along the second edge 322 and/or the first edge 321. Preferably, the portions of glue are deposited on the edge 322 of the panels 301, 302, 303, 304 facing the fixing flange 321, so that, when approach and put the clamp 321 in pressure on the second edge 322, the glue is crushed outwards. In this way, if the junction between the fixing flange 321 and the second edge 322 is caused to creep by thermal expansion, the creep can open outwards in order to guarantee the tightness of the skylight 1.

Comme visible sur la figure 4 , le premier bord 421 est riveté E6 au deuxième bord 422, les parties de rebord ou le rebord 31 étant toujours posé(es) sur le bâti plat.As seen on the figure 4 , the first edge 421 is riveted E6 to the second edge 422, the rim portions or the rim 31 still being placed on the flat frame.

Dans le cas où le corps n'est formé que d'un seul panneau cintré et/ou plié, le panneau cintré et/ou plié formant le corps est alors rapporté et fixé au rebord, typiquement par rivetage et collage, selon la même méthode, ou par soudure, en ménageant un cordon de soudure interne à la jonction entre rebord et corps et un cordon externe à la jonction entre rebord et corps. La base est ensuite rapportée et fixée au panneau cintré et/ou plié formant le corps, typiquement par rivetage et collage, selon la même méthode, ou par soudure, en ménageant un cordon de soudure interne à la jonction entre base et corps et un cordon externe à la jonction entre base et corps.In the case where the body is only formed of a single curved and/or folded panel, the curved and/or folded panel forming the body is then attached and fixed to the rim, typically by riveting and gluing, according to the same method. , or by welding, providing an internal weld bead at the junction between flange and body and an external bead at the junction between flange and body. The base is then attached and fixed to the curved and/or folded panel forming the body, typically by riveting and gluing, using the same method, or by welding, leaving an internal weld bead at the junction between base and body and a bead external to the junction between base and body.

En définitive, la costière 3 est montée à l'envers sur le bâti plat, le rebord 31 étant en contact avec le bâti plat pour garantir la planéité. La costière 3 est ensuite retournée pour mettre en œuvre les étapes suivantes de fabrication.Ultimately, the curb 3 is mounted upside down on the flat frame, the flange 31 being in contact with the flat frame to ensure flatness. Curb 3 is then turned over to implement the following manufacturing steps.

L'organe de fixation, qui est de préférence un rivet taraudé borgne 7, est ensuite fixé E7 à la costière 3, de préférence au rebord 31 de la costière 7, de manière privilégiée par rivetage. Ceci est mis en œuvre par insertion de rivets 7 au sein de chacun des orifices 313 du rebord 31 de la costière 3 prévus à cet effet, puis par traction sur le tirant et déformation de la portion de faiblesse à travers la tête de chaque rivet 7, ce qui assure une étanchéité autour de chaque orifice 313 ménagé dans le rebord 31. The fastening member, which is preferably a blind threaded rivet 7, is then fixed E7 to the curb 3, preferably to the rim 31 of the curb 7, preferably by riveting. This is implemented by inserting rivets 7 within each of the orifices 313 of the rim 31 of the curb 3 provided for this purpose, then by pulling on the tie rod and deforming the weak portion through the head of each rivet 7 , which ensures a seal around each orifice 313 made in the flange 31.

Chaque entretoise 6 est ensuite fixée E8 à la costière 3, par vissage de leur téton 61 dans les rivets taraudés borgnes 7 qui sont rivetés à la costière 3. Each spacer 6 is then fixed E8 to the curb 3, by screwing their stud 61 into the blind threaded rivets 7 which are riveted to the curb 3.

Le vitrage 2 est positionné E9 sur le rebord 31 de la costière 3, dans l'espace délimité par les entretoises 6. Glazing 2 is positioned E9 on edge 31 of curb 3, in the space delimited by spacers 6.

Enfin, la parclose 4 est agencée sur le vitrage 2 et fixée E10 à la costière 3 au moyen des vis 8 et des rondelles 9 du système de fixation. Chaque vis 8 traverse la parclose 4 pour coopérer avec l'orifice taraudé borgne 62 de l'entretoise 6. Le serrage de chaque vis 8 est mis en œuvre, de préférence, à la clef dynamométrique, dont l'intensité de serrage est contrôlée au dixième de Newton grâce à la présente des entretoises 6. Alternativement, la fixation E10 est réalisée par serrage d'un écrou sur chaque tige filetée faisant saillie de la section de corps de chaque entretoise, lesquelles tiges filetées traversent la parclose, de préférence au moyen d'une clef dynamométrique.Finally, the glazing bead 4 is arranged on the glazing 2 and fixed E10 to the curb 3 by means of screws 8 and washers 9 of the fastening system. Each screw 8 passes through the glazing bead 4 to cooperate with the blind threaded hole 62 of the spacer 6. The tightening of each screw 8 is implemented, preferably, with a torque wrench, the tightening intensity of which is controlled by tenth of a Newton thanks to the presence of spacers 6. Alternatively, the E10 fixing is made by tightening a nut on each threaded rod projecting from the body section of each spacer, which threaded rods pass through the glazing bead, preferably by means with a torque wrench.
