Description

La présente invention concerne les couvertures isolantes et étanches et tout particulièrement les couvertures de bâtiments industriels.The present invention relates to insulating and waterproof covers and very particularly to industrial building covers.

Ces couvertures fixées sur une charpente comportent une isolation thermique entre l'élément porteur et le revêtement d'étanchéité. Cette isolation est principalement réalisée par des plaques ou panneaux posés jointivement. La solidarisation de ces plaques avec l'élément porteur est exécutée par fixation mécanique lorsque le support est en tôles d'acier nervuré.These covers fixed on a frame include thermal insulation between the load-bearing element and the waterproofing coating. This insulation is mainly achieved by plates or panels placed contiguously. The joining of these plates with the carrier element is carried out by mechanical fixing when the support is made of ribbed steel sheets.

Une fixation mécanique est constituée d'une vis, ou d'un rivet ou d'un goujon, rendu solidaire de la tôle d'acier nervurée par perçage ou par soudage. En partie haute la tête de vis, de rivet, de goujon, comporte une rondelle de petites dimensions, d'un diamètre de l'ordre de 50 à 70 mm.A mechanical fixing consists of a screw, or a rivet or a stud, made integral with the ribbed steel sheet by drilling or welding. In the upper part, the head of the screw, rivet, stud, includes a washer of small dimensions, with a diameter of the order of 50 to 70 mm.

Le revêtement d'étanchéité est rendu solidaire des plaques d'isolation par collage ou par soudage à l'aide d'une source chaude, le plus souvent par un chalumeau à flamme ou à air, sur toute la surface des panneaux isolants et ou au droit des rondelles des fixations mécaniques ; ces dernières peuvent être améliorées pour la soudure par un revêtement de surface approprié ou par une rondelle de même matière que le revêtement d'étanchéité, et de plus grandes dimensions, interposée entre la rondelle métallique et le panneau isolant sous-jacent.The waterproofing coating is made integral with the insulation plates by gluing or by welding using a hot source, most often by a flame or air torch, over the entire surface of the insulating panels and or right of the washers of the mechanical fixings; these can be improved for welding by a suitable surface coating or by a washer of the same material as the sealing coating, and of larger dimensions, interposed between the metal washer and the underlying insulating panel.

Une technique plus récente prévoit le déroulage à sec sur les panneaux isolants d'un premier lit de feuilles constituant la partie inférieure du revêtement d'étanchéité ; les fixations mécaniques traversent alors le lit de feuilles et les panneaux isolants. Dans le cas de panneaux sensibles à la flamme d'un chalumeau, un écran thermique préalable peut être mis en oeuvre sur l'isolant. La partie supérieure du revêtement d'étanchéité est ensuite collée ou soudée sur la partie inférieure comportant ses rondelles apparentes.A more recent technique provides for the dry unwinding on the insulating panels of a first bed of sheets constituting the lower part of the waterproofing coating; the mechanical fixings then pass through the bed of sheets and the insulating panels. In the case of panels sensitive to the flame of a torch, a preliminary heat shield can be used on the insulation. The upper part of the waterproof coating is then glued or welded to the lower part with its visible washers.

Une autre technique prévoit des fixations mécaniques au droit des joints de recouvrement des lés du revêtement d'étanchéité. La partie recouverte est collée ou soudée, d'une part sur la lisière du lé adjacent et, d'autre part, sur les petites rondelles des fixations.Another technique provides for mechanical fastenings to the right of the covering joints of the strips of the waterproofing coating. The covered part is glued or welded, on the one hand on the edge of the adjacent strip and, on the other hand, on the small washers of the fixings.

Le vent crée d'importants efforts de compression et de dépression,par emplacements,sur la couverture (tourbillons, effet de masque derrière une paroi ou une émergence de la toiture). Les efforts sont exercés sur la surface extérieure, donc sur le revêtement d'étanchéité,qui sollicite in fine l'élément porteur et la structure du bâtiment.The wind creates significant compression and depression forces, in places, on the roof (swirls, mask effect behind a wall or an emergence of the roof). The forces are exerted on the exterior surface, therefore on the waterproofing coating, which ultimately stresses the load-bearing element and the structure of the building.

Dans le domaine compris entre revêtement d'étanchéité et élément porteur, ces efforts créent, au niveau d'une ou plusieurs fixations, des forces d'arrachement perpendiculaires et parallèles à la surface de couverture. Ces derniers efforts sont d'autant plus importants que les dispositifs de fixations sont écartés. Ils peuvent entraîner des déchirures du revêtement en tête de fixation et/ou arracher les fixations au droit de leur liaison avec la charpente ou l'élément porteur par effet de couple ou de traction.In the area between the waterproofing coating and the supporting element, these forces create, at one or more fastenings, tearing forces perpendicular and parallel to the covering surface. These latter efforts are all the more important as the fastening devices are removed. They can cause tears in the coating at the head of the fastener and / or tear off the fasteners in line with their connection with the frame or the load-bearing element by the effect of torque or traction.

Pour ces deux dernières techniques, au moins une feuille du revêtement d'étanchéité est percée par la fixation mécanique.For the latter two techniques, at least one sheet of the sealing coating is pierced by the mechanical fixing.

Dans tous les cas, dans le but de résister aux forces de dépression créées par le vent, les normes françaises définies dans le cadre du D.T.U. 43.3 et les usages prévoient un minimum de cinq fixations par m² de toiture, partant du fait qu'une fixation résiste à environ 900 N à l'arrachement.In all cases, in order to resist the vacuum forces created by the wind, the French standards defined within the framework of DTU 43.3 and the uses provide for a minimum of five fixings per m² of roof, starting from the fact that a fixing withstands about 900 N tearing.

La rupture se situe au niveau du plan de collage du revêtement d'étanchéité sur la rondelle, ou par déboutonnage de la tête de fixation au travers de la rondelle, ou par arrachement de la fixation au travers de la tôle d'acier nervuré. Les valeurs de rupture sont relativement homogènes, de l'ordre de 900 à 1300 N.The rupture is located at the level of the sealing surface of the sealing coating on the washer, or by unbuttoning the fixing head through the washer, or by tearing off the fixing through the ribbed steel sheet. The breaking values are relatively homogeneous, of the order of 900 to 1300 N.

Le grand nombre de fixations rend la mise en oeuvre longue et coûteuse. De plus, la performance du revêtement d'étanchéité est considérablement diminuée au droit des fixations, soit parce que le revêtement est percé en partie, soit parce qu'il peut être poinçonné par la tête de fixation traversant la rondelle, ou encore déchiré à la périphérie de la rondelle lorsque cette dernière est bloquée, de façon hyperstatique, sur la tige de la fixation, comme décrit dans le brevet français 1.522.378; ce phénomène favorise le désoudage du goujon de la tôle d'acier nervuré. Ces inconvénients sont considérablement accrus lorsque les panneaux isolants sont compressibles, bien qu'élastiques.The large number of fasteners makes installation time-consuming and expensive. In addition, the performance of the waterproofing coating is considerably reduced in relation to the fasteners, either because the coating is partially drilled, or because it can be punched by the fixing head passing through the washer, or even torn with periphery of the washer when the latter is blocked, hyperstatically, on the rod of the fixing, as described in French patent 1,522,378; this phenomenon promotes the desoldering of the stud from the ribbed steel sheet. These drawbacks are considerably increased when the insulating panels are compressible, although elastic.

La présente invention a pour but de réaliser une couverture dont la mise en oeuvre soit plus simple et plus rapide que celle des ouvertures classiques et dont par ailleurs la tenue au vent soit améliorée.The object of the present invention is to provide a cover the implementation of which is simpler and faster than that of conventional openings and the wind resistance of which is also improved.

A cet effet, l'invention a pour objet une couverture étanche, notamment pour bâtiment industriel, comportant un élément porteur adapté pour être fixé sur un élément de charpente du bâtiment, une couche d'un matériau isolant disposé sur l'élément porteur, et un revêtement d'étanchéité recouvrant la couche de matériau isolant, des moyens de liaison étant prévus pour maintenir assemblés ces trois constituants, caractérisée en ce que les moyens de liaison comprennent un premier organe de fixation fixant sur la charpente l'élément porteur et comportant au-dessus de celui-ci un prolongement de longueur sensiblement égale à l'épaisseur de la couche isolante, et une plaque souple et un deuxième organe de fixation prenant appui sur cette plaque souple par l'intermédiaire d'une tête élargie et/ou d'une rondelle rigide et venant se fixer sur ledit prolongement, la dimension de la tête élargie ou de la rondelle rigide étant intermédiaire entre la dimension maximale du premier ou du deuxième organe au voisinage de la surface externe de la couche de matériau isolant, et la dimension de la plaque souple, et en ce que le revêtement d'étanchéité est fixé uniquement sur les plaques souples.To this end, the subject of the invention is a waterproof cover, in particular for an industrial building, comprising a support element adapted to be fixed to a structural member of the building, a layer of insulating material placed on the support element, and a sealing coating covering the layer of insulating material, connecting means being provided to keep these three constituents assembled, characterized in that the connecting means comprise a first fixing member fixing the support element to the frame and comprising above it an extension of length substantially equal to the thickness of the insulating layer, and a flexible plate and a second fixing member bearing on this flexible plate by means of an enlarged head and / or of a rigid washer and coming to be fixed on said extension, the dimension of the enlarged head or of the rigid washer being intermediate. between the maximum dimension of the first or second member in the vicinity of the external surface of the layer of insulating material, and the dimension of the flexible plate, and in that the sealing coating is fixed only on the flexible plates.

De cette manière, le revêtement d'étanchéité qui sera fixé sur les plaques souples sera rendu solidaire de la charpente : par ailleurs, l'invention permet également de solidariser l'élément porteur avec la charpente, si bien que tous les efforts de dépression subis par la couverture seront reportés sur l'élément de charpente, panne ou poutre.In this way, the sealing coating which will be fixed on the flexible plates will be made integral with the frame: moreover, the invention also makes it possible to secure the load-bearing element with the frame, so that all the efforts of depression suffered by the cover will be transferred to the structural element, purlin or beam.

Ce dispositif à haute performance permet de mettre en oeuvre au maximum une fixation par m² de couverture (voire une pour 2 m²), divisant ainsi par plus de 5, par rapport aux techniques classiques préalablement décrites, le nombre total de fixations.This high performance device makes it possible to use a maximum of one fixing per m² of coverage (or even one for 2 m²), thus dividing by more than 5, compared to the conventional techniques previously described, the total number of fastenings.

Dans le cas d'une charpente en acier, la vis précitée peut être une vis autotaraudeuse. Dans le cas d'une charpente en béton, la vis précitée est engagée dans un insert métallique de l'élément de charpente.In the case of a steel frame, the aforementioned screw can be a self-tapping screw. In the case of a concrete frame, the aforementioned screw is engaged in a metal insert of the frame element.

D'autres caractéristiques et avantages de l'invention ressortiront de la description qui suit d'exemples de réalisation de l'invention,, faite en se référant aux dessins ci-annexés sur lesquels :

  • la Figure 1 est une représentation schématique en coupe d'un premier mode de réalisation de l'invention;
  • la Figure 2 est une représentation schématique en coupe d'un deuxième mode de réalisation de l'invention;
  • la Figure 3 est une vue en coupe le long d'un élément de charpente et correspond au mode de réalisation de la Figure 2;
  • les Figures 4 et 5 illustrent un mode de réalisation particulier de l'invention.
Other characteristics and advantages of the invention will emerge from the description which follows of embodiments of the invention, made with reference to the attached drawings in which:
  • Figure 1 is a schematic sectional representation of a first embodiment of the invention;
  • Figure 2 is a schematic sectional representation of a second embodiment of the invention;
  • Figure 3 is a sectional view along a structural member and corresponds to the embodiment of Figure 2;
  • Figures 4 and 5 illustrate a particular embodiment of the invention.

On voit sur les Figures 1 et 2 un élément de charpente constitué par une poutrelle en acier 1 constituant une panne d'une charpente : un élément porteur 2 constitué par une tôle d'acier nervurée est disposé transversalement sur les pannes 1.We see in Figures 1 and 2 a frame element consisting of a steel beam 1 constituting a breakdown of a frame: a load-bearing element 2 constituted by a ribbed steel sheet is arranged transversely on the purlins 1.

Une couche isolante 3 constituée, par exemple, par des plaques de matière isolante, est placée sur l'élément porteur 2; la couverture ou toiture est complétée par un revêtement d'étanchéité 10 qui vient se placer sur la face extérieure de la couche isolante 3.An insulating layer 3 constituted, for example, by plates of insulating material, is placed on the carrier element 2; the cover or roof is completed by a sealing coating 10 which is placed on the outer face of the insulating layer 3.

Le dispositif de fixation selon l'invention comporte un premier organe fixe comportant une vis 4 qui est fixée sur la panne 1 avec interposition de l'élément support 2, qui est donc ainsi solidarisé avec la charpente.The fixing device according to the invention comprises a first fixed member comprising a screw 4 which is fixed to the purlin 1 with the interposition of the support element 2, which is thus thus secured to the frame.

Ce premier organe sert tout d'abord à fixer l'élément porteur 2 sur la panne de charpente 1; il constitue aussi un élément constitutif des moyens de liaison des trois constituants de la couverture, à savoir l'élément porteur 2, la couche isolante 3 et le revêtement d'étanchéité 10.This first member serves first of all to fix the carrier element 2 to the frame failure 1; it also constitutes a constitutive element of the means of connection of the three constituents of the cover, namely the carrier element 2, the insulating layer 3 and the sealing coating 10.

Avantageusement, la vis 4 est une vis autotaraudeuse. Dans le cas d'une charpente en bêton, cette vis s'engage dans un insert métallique de l'élément de charpente.Advantageously, the screw 4 is a self-tapping screw. In the case of a concrete frame, this screw engages in a metal insert of the frame element.

La tête 5 de la vis 4 comporte un prolongement aligné avec le fût de la vis et disposé de l'autre côté de la tête 5. Dans le premier mode de réalisation, ce prolongement est constitué par une pièce intermédiaire cylindrique creuse 6 filetée intérieurement, ouverte à son extrémité libre et dont le fond 20 est fixé sur l'élément porteur par l'intermédiaire de la vis 4. Dans le mode de réalisation de la Figure 2, le prolongement est constitué par une tige filetée 7. La longueur du cylindre 6 ou de la tige 7 est sensiblement égale à la somme des épaisseurs de la couche isolante 3 et de l'élément porteur.The head 5 of the screw 4 has an extension aligned with the barrel of the screw and disposed on the other side of the head 5. In the first embodiment, this extension consists of a hollow cylindrical intermediate piece 6 internally threaded, open at its free end and the bottom 20 of which is fixed to the carrier element by means of the screw 4. In the embodiment of FIG. 2, the extension consists of a threaded rod 7. The length of the cylinder 6 or of the rod 7 is substantially equal to the sum of the thicknesses of the insulating layer 3 and of the carrier element.

Un deuxième organe comportant une partie constituant une rondelle rigide vient se solidariser avec le premier organe précité. Dans le cas de la Figure 1, il s'agit d'une vis 8 qui s'engage dans le cylindre 6, qui présente une tête plate fraisée et sur laquelle est engagée une rondelle rigide 9 de diamètre a.A second member comprising a part constituting a rigid washer comes to join with the aforementioned first member. In the case of Figure 1, it is a screw 8 which engages in the cylinder 6, which has a flat countersunk head and on which is engaged a rigid washer 9 of diameter a .

Dans le mode de réalisation de la Figure 2, le deuxième organe est constitué par une sorte de bouchon 11 qui présente une partie tubulaire 12 filetée intérieurement qui coopère avec la tige 7 et qui est surmontée par une tête plate rigide 13 constituant une rondelle d'appui similaire à la rondelle rigide 9.In the embodiment of Figure 2, the second member is constituted by a sort of plug 11 which has a tubular part 12 internally threaded which cooperates with the rod 7 and which is surmounted by a rigid flat head 13 constituting a washer support similar to the rigid washer 9.

Le dispositif de fixation comporte enfin une plaque souple 21 qui est interposée entre la rondelle rigide 9 ou la tête plate rigide 13 et les panneaux isolants 3. Cette plaque 21 est de préférence circulaire de diamètre D et de grandes dimensions.The fixing device finally comprises a flexible plate 21 which is interposed between the washer rigid 9 or the rigid flat head 13 and the insulating panels 3. This plate 21 is preferably circular with diameter D and large dimensions.

Cette plaque souple est, par exemple, réalisée en métal de faible épaisseur et peut comporter un revêtement de surface compatible avec le matériau constituant le revêtement d'étanchéité. On peut également utiliser un matériau comportant une armature tissée ou non tissée, en verre, en polyester, en matière organique ou en un mélange de ces composants; dans ce cas, la plaque est enduite d'une matière identique ou compatible avec celle du revêtement d'étanchéité.This flexible plate is, for example, made of thin metal and may include a surface coating compatible with the material constituting the sealing coating. It is also possible to use a material comprising a woven or non-woven reinforcement, made of glass, polyester, organic material or a mixture of these components; in this case, the plate is coated with a material identical or compatible with that of the sealing coating.

Avantageusement, la plaque précitée peut être rendue préalablement solidaire de la rondelle 9 ou de la tête rigide 13 par collage ou soudage.Advantageously, the aforementioned plate can be made previously integral with the washer 9 or with the rigid head 13 by gluing or welding.

Dans le mode de réalisation de la Figure 1 comportant un premier organe constitué par une vis, on peut également prévoir que la plaque souple soit sertie entre deux rondelles rigides correspondant à la rondelle 9.In the embodiment of FIG. 1 comprising a first member constituted by a screw, provision may also be made for the flexible plate to be crimped between two rigid washers corresponding to the washer 9.

La rondelle rigide 9 ou la tête plate 13 peut présenter un diamètre a de l'ordre de 80 mm.The rigid washer 9 or the flat head 13 may have a diameter a of the order of 80 mm.

La plaque souple 21 doit présenter une résistance mécanique en traction répondant à la relation Rtπa > 5000 N et de préférence de l'ordre de 8000 N, la résistance mécanique à la traction Rt étant exprimée en Newtons par cm de largeur et mesurée selon la norme NF G07-001. Elle doit également présenter une résistance à la déchirure Rd (mesurée selon la méthode UEATC 5.4.1., juillet 1982) qui soit au moins égale à 200 N et de préférence de l'ordre de 400 N. A cet effet, le diamètre d de la pièce cylindrique 6, dans le mode de réalisation de la Figure 1, ou du deuxième organe 11, dans le mode de réalisation de la Figure 2, au voisinage de la surface externe de la couche 3 de matériau isolant, ne doit pas être inférieur à 6 mm et de préférence de l'ordre de 10 mm.The flexible plate 21 must have a mechanical tensile strength corresponding to the relationship R t πa> 5000 N and preferably of the order of 8000 N, the mechanical tensile strength R t being expressed in Newtons per cm of width and measured according to standard NF G07-001. It must also have a tear resistance Rd (measured according to the UEATC method 5.4.1., July 1982) which is at least equal to 200 N and preferably of the order of 400 N. For this purpose, the diameter d of cylindrical part 6, in the embodiment of Figure 1, or the second member 11, in the embodiment of Figure 2, in the vicinity of the outer surface of the layer 3 of insulating material, should not be less than 6 mm and preferably of the order of 10 mm.

Par ailleurs, la différence entre le diamètre D de la plaque 21 et le diamètre a de la rondelle rigide ou de la tête plate 13 doit être au moins égale à 100 mm et de préférence de l'ordre de 170 mm. Il en résulte que l'on peut, par exemple, utiliser une plaque souple dont le diamètre D est de l'ordre de 250 mm.Furthermore, the difference between the diameter D of the plate 21 and the diameter a of the rigid washer or of the flat head 13 must be at least equal to 100 mm and preferably of the order of 170 mm. As a result, one can, for example, use a flexible plate whose diameter D is of the order of 250 mm.

Avantageusement, le diamètre de la rondelle ou tête rigide a et le diamètre d de l'élément de fixation sont choisis de telle manière que la différence (a-d) soit environ égale à 90 mm et de toute façon supérieure à 70 mm. Ceci permet d'éviter que la plaque souple 21 ne laisse "échapper" la pièce rigide 8 ou 13 par glissement, déchirure ou déboutonnage.Advantageously, the diameter of the washer or rigid head a and the diameter d of the fastening element are chosen such that the difference (ad) is approximately equal to 90 mm and in any case greater than 70 mm. This prevents the flexible plate 21 from "escaping" the rigid part 8 or 13 by sliding, tearing or unbuttoning.

La Figure 3 est une vue en coupe perpendiculaire à la Figure 2 et montre le mode de fixation de l'élément porteur 2 sur la panne 1. On voit que la tige 7 est solidaire de la tête de la vis autotaraudeuse 4, qui est fixée dans un creux de la tôle nervurée 2 sur la panne 1 avec interruption d'une rondelle 14.Figure 3 is a sectional view perpendicular to Figure 2 and shows the method of fixing the carrier element 2 on the purlin 1. We see that the rod 7 is secured to the head of the self-tapping screw 4, which is fixed in a hollow in the ribbed sheet 2 on the purlin 1 with interruption of a washer 14.

Avantageusement, le dispositif de fixation selon l'invention comporte au moins un élément isolant thermiquement pour éviter la formation de ponts thermiques.Advantageously, the fixing device according to the invention comprises at least one thermally insulating element to avoid the formation of thermal bridges.

Les Figures 4 et 5 représentent une variante de réalisation de l'invention. Celle-ci est destinée en particulier au cas de pannes de rive 41 qui sont directement adjacentes à un acrotère 42.Figures 4 and 5 show an alternative embodiment of the invention. This is intended in particular in the case of bank failures 41 which are directly adjacent to an acroterion 42.

Dans ce cas, l'axe du point de fixation du revêtement d'étanchéité est déporté par rapport à l'axe de fixation de l'élément porteur sur la panne. A cet effet, le premier organe est constitué par deux vis 51 et 52 disposées symétriquement par rapport à l'axe de la panne 41, qui constitue l'axe de fixation de la tôle nervurée 44 sur la panne 1.In this case, the axis of the fixing point of the sealing coating is offset relative to the axis of fixing of the carrier element on the purlin. To this end, the first member is constituted by two screws 51 and 52 arranged symmetrically with respect to the axis of the purlin 41, which constitutes the axis of attachment of the ribbed sheet 44 on the purlin 1.

Ces vis servent à la fixation d'une extrémité d'une base 43 sur la panne 41. Cette base présente de préférence, en section transversale (Figure 5) la forme d'un U. Cette base 43 porte à une de ses extrémités une partie cylindrique creuse 45 analogue à la pièce cylindrique 6 de la Figure 1.These screws are used to fix one end of a base 43 on the purlin 41. This base preferably has, in cross section (Figure 5) the shape of a U. This base 43 carries at one of its ends a hollow cylindrical part 45 similar to the cylindrical part 6 of FIG. 1.

On voit que l'axe de la pièce creuse est déporté par rapport à l'axe de la panne 41. On peut évidemment prévoir une disposition semblable dans laquelle la base 43 supporte une tige analogue à la tige 7 de la Figure 2.It can be seen that the axis of the hollow part is offset relative to the axis of the purlin 41. It is obviously possible to provide a similar arrangement in which the base 43 supports a rod similar to the rod 7 of FIG. 2.

La réalisation d'une couverture conforme à la présente invention peut s'effectuer de la manière suivante. On fixe tout d'abord l'élément porteur (tôle nervurée) sur les poutres ou pannes de la charpente au moyen des organes fixes 4; on met en place les panneaux de la couche isolante en les "empalant" sur les prolongements 6 respectivement 7 de ces premiers organes; on met en place les plaques souples dans le cas où elles ne sont pas solidarisées des rondelles rigides, et on procède ensuite à la fixation des deuxièmes organes 8, 11 sur les premiers organes de manière à solidariser ces derniers avec l'élément porteur et la panne ou poutre. On met en place ensuite le revêtement d'étanchéité et on réalise sa fixation par soudage ou collage sur la plaque souple et la rondelle rigide des dispositifs selon l'invention.The realization of a cover according to the present invention can be carried out as follows. First of all, the carrier element (ribbed sheet) is fixed to the beams or purlins of the frame by means of the fixed members 4; the insulating layer panels are put in place by "impaling" them on the extensions 6 and 7 respectively of these first members; the flexible plates are put in place in the event that they are not secured to the rigid washers, and then the second members 8, 11 are fixed to the first members so as to secure the latter with the carrier element and the purlin or beam. The sealing coating is then put in place and it is fixed by welding or gluing on the flexible plate and the rigid washer of the devices according to the invention.

Les différents éléments mécaniques (vis autotaraudeuse, premier organe, deuxième organe) sont dimensionnés de manière à présenter une résistance à l'arrachement de l'ordre de 5000 N; de cette façon, on obtient un ensemble homogène qui présente une résistance à l'arrachement de 5000 N et tous les efforts résultant d'une dépression subie par le revêtement d'étanchéité sont transmis directement à la charpente par les organes de fixation.The various mechanical elements (self-tapping screw, first member, second member) are dimensioned so as to have a pull-out resistance of the order of 5000 N; in this way, a homogeneous assembly is obtained which has a tear resistance of 5000 N and all the forces resulting from a depression undergone by the waterproofing coating are transmitted directly to the frame by the fixing members.

Le nombre de fixations au m² étant très fortement réduit, le prix de revient et le temps de mise en place d'une couverture sont fortement réduits, ce qui permet de réaliser des couvertures de grandes surfaces, en particulier des couvertures de bâtiments industriels.As the number of fastenings per m² is very greatly reduced, the cost price and the time required to install a cover are greatly reduced, which makes it possible to produce covers for large areas, in particular covers for industrial buildings.

D'autre part, en cas de circulation sur la couverture ou de charges de compression, le revêtement d'étanchéité suit les mouvements de la plaque souple et ne peut donc être déchiré au droit de la périphérie de la rondelle rigide. On peut utiliser des isolants très compressibles pour la couche isolante, ce qui permet de réduire encore le prix de revient et ce, en particulier, dans le cas où l'on prévoit un sertissage de la plaque souple entre deux rondelles rigides.On the other hand, in the event of circulation on the cover or of compression loads, the sealing coating follows the movements of the flexible plate and cannot therefore be torn off at the periphery of the rigid washer. It is possible to use highly compressible insulations for the insulating layer, which makes it possible to further reduce the cost price and this, in particular, in the case where provision is made for crimping the flexible plate between two rigid washers.

On peut par exemple utiliser de la laine de roche ayant une masse volumique inférieure à 120 kg/m³ et de préférence égale à 100 kg/m³ au lieu de la laine de roche de 150 kg/m³ utilisée actuellement.One can for example use rock wool having a density lower than 120 kg / m³ and preferably equal to 100 kg / m³ instead of rock wool 150 kg / m³ currently used.

On peut également utiliser de la laine de verre dont la masse volumique est inférieure à 90 kg/m³ en lieu et place de laine de verre de masse volumique de 110 kg/m³.Glass wool with a density less than 90 kg / m³ can also be used in place of glass wool with a density of 110 kg / m³.
