Description

DOMAINE TECHNIQUE DE L'INVENTIONTECHNICAL FIELD OF THE INVENTION

La présente invention concerne un bloc pour constituer un mur, un procédé de constitution d'un tel bloc et un mur porteur comportant un tel bloc. Elle s'applique notamment aux systèmes constructifs en maçonnerie.The present invention relates to a block for constituting a wall, a method of forming such a block and a load-bearing wall comprising such a block. It applies in particular to building systems in masonry.

ETAT DE LA TECHNIQUESTATE OF THE ART

Dans le domaine de la maçonnerie, le choix d'un système constructif au profit d'un autre pour la construction d'un mur résulte des contraintes qu'il impose au chantier en comparaison des avantages qu'il offre. Ainsi, le poids du système constructif, sa vitesse d'assemblage et sa résistance mécanique représentent des limitations déterminantes. Par ailleurs, sa performance thermique (l'isolation qu'il fournit), aujourd'hui encadré fermement par la réglementation, constitue également une variable importante pour l'acceptation d'un système constructif au profit d'un autre.In the field of masonry, the choice of a constructive system for the benefit of another for the construction of a wall results from the constraints it imposes on the site in comparison with the advantages it offers. Thus, the weight of the constructive system, its assembly speed and its mechanical strength are decisive limitations. Moreover, its thermal performance (the insulation it provides), which is now tightly regulated by regulations, is also an important variable for the acceptance of a constructive system for the benefit of another.

A ce jour, il existe trois familles de systèmes constructifs :

  • le système utilisant des blocs à isolation répartie (béton cellulaire, brique monomur par exemple). Dans ce système, l'ajout d'un isolant complémentaire sur le mur n'est pas nécessaire dans la mesure où celui-ci dispose déjà de propriétés isolantes en raison de sa structure alvéolaire constituée de millions de bulles d'air (l'air étant un isolant dit « parfait »). Pour autant, sa construction réclame la manutention importante de charges lourdes et des délais importants de mise en oeuvre. En outre, ce système n'offre pas les performances thermiques suffisantes pour se conformer aux futures exigences de la réglementation dans la mesure où ses caractéristiques d'isolation sont pauvres à l'endroit des ponts thermiques (angles, linteaux, jonction entre les blocs) ce qui nécessite l'utilisation d'un autre système isolant à ces emplacements. De plus, le passage de gaines électriques dans le système constructif implique un rainurage et un rebouchage au plâtre qui imposent un travail supplémentaire ;
  • le système utilisant des blocs de bétons manufacturés (aggloméré béton, brique creuse). Dans ce système, l'ajout d'un isolant complémentaire à l'intérieur et/ou extérieur de la brique est nécessaire car le bloc n'est lui-même pas ou peu isolant. Sa construction réclame également la manutention importante de charges lourdes et des délais importants de mise en oeuvre. De plus, ce système ne permet pas de gérer seul le cas des ponts thermiques et nécessite l'utilisation d'un autre système. Sa pose requiert, en outre, une excellente technicité sous peine de désordres structurels importants ; et
  • le système utilisant des blocs de coffrage en polystyrène dans lequel est coulé du béton entre des façades en polystyrène. Dans ce système, la faible tenue du polystyrène nécessite de contreventer les parois avant le coulage du béton entrainant des coûts et du temps de mise en place supplémentaires. De plus, la pose des divers éléments constructifs est, pour la même raison, problématique et nécessite l'utilisation de contre-cloisons sur ossature rapportée.
To date, there are three families of building systems:
  • the system using distributed insulation blocks (cellular concrete, monomur brick for example). In this system, the addition of a complementary insulation on the wall is not necessary insofar as it already has insulating properties because of its honeycomb structure consisting of millions of air bubbles (the air being an insulation called "perfect"). However, its construction requires heavy handling of heavy loads and significant delays in implementation. In addition, this system does not offer sufficient thermal performance to comply with future regulatory requirements insofar as its insulation characteristics are poor at thermal bridges (angles, lintels, junction between blocks) which requires the use of another insulating system at these locations. In addition, the passage of electrical ducts in the constructive system involves a grooving and plaster filling which impose additional work;
  • the system using manufactured concrete blocks (concrete chipboard, hollow brick). In this system, the addition of a complementary insulator inside and / or outside the brick is necessary because the block itself is not or little insulation. Its construction also requires significant handling of loads heavy delays and delays in implementation. In addition, this system does not manage alone the case of thermal bridges and requires the use of another system. His pose also requires excellent technicality or serious structural disorders; and
  • the system using polystyrene formwork blocks in which concrete is poured between polystyrene facades. In this system, the low resistance of the polystyrene requires forging the walls before pouring the concrete resulting in additional costs and installation time. In addition, the installation of the various constructive elements is, for the same reason, problematic and requires the use of counter-partitions on reported framework.

On connaît le document WO 03/095755 qui décrit un système de construction modulaire. Cependant, ce système de construction modulaire ne permet pas d'élaborer une attache d'un parement à la façade intérieure du bloc sans ajout d'un quelconque support supplémentaire tout en ménageant un vide entre la façade et le parement pour le passage de gaines et canalisations.We know the document WO 03/095755 which describes a modular building system. However, this modular construction system does not allow to develop a fastening of a facing the inner face of the block without adding any additional support while leaving a gap between the facade and the facing for the passage of ducts and pipes.

Les combinaisons actuelles de moyens ne permettent ainsi pas de répondre de manière optimisée aux contraintes de :

  • poids,
  • résistance mécanique (aussi appelée rigidité), notamment selon les normes parasismiques,
  • rapidité de mise en place et
  • isolation thermique.
The current combinations of means thus do not make it possible to respond optimally to the constraints of:
  • weight,
  • mechanical resistance (also known as rigidity), particularly according to earthquake-resistant standards,
  • speed of implementation and
  • thermal insulation.

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

La présente invention vise à remédier à tout ou partie de ces inconvénients.The present invention aims to remedy all or part of these disadvantages.

A cet effet, selon un premier aspect, la présente invention vise un bloc, qui comporte :

  • une façade intérieure en particules de bois collées et pressées à chaud,
  • un support d'isolant extérieur, en particules de bois collées et pressées à chaud,
  • au moins deux écarteurs en particules de bois collées et pressées à chaud reliant mécaniquement la façade intérieure et le support d'isolant,
  • des moyens d'assemblage à un bloc identique,
  • une couche d'isolation solidaire du support d'isolant extérieur et
  • au moins un montant en particules de bois collées sur la façade intérieure.
For this purpose, according to a first aspect, the present invention aims a block, which comprises:
  • an internal facade made of glued and hot pressed wood particles,
  • an external insulation support, in glued and hot pressed wood particles,
  • at least two spacers in glued and hot-pressed wood particles mechanically connecting the inner face and the insulating support,
  • assembly means to an identical block,
  • an insulating layer secured to the outer insulation support and
  • at least one amount of wood particles stuck on the interior facade.

Le matériau en particules de bois collées et pressées à chaud est un matériau dense (850kg/m3) plus rigide et résistant que l'aggloméré. Il offre donc le premier avantage de permettre la construction de blocs ayant de bonnes propriétés mécaniques. Par ailleurs, un tel bloc est léger (7,2 kg) ce qui le rend facilement transportable et réduit son temps de pose. Les moyens d'assemblage assurent une grande rapidité de mise en place. La couche d'isolation, solidaire du support d'isolant extérieur, donne au bloc une capacité d'isolation thermique importante.The glued and hot pressed wood particle material is a dense (850kg / m3) material that is stiffer and more resistant than chipboard. It therefore offers the first advantage of allowing the construction of blocks having good mechanical properties. Moreover, such a block is lightweight (7.2 kg) which makes it easily transportable and reduces its exposure time. The assembly means ensure a high speed of implementation. The insulation layer, integral with the outer insulation support, gives the block a significant thermal insulation capacity.

Ainsi, la présente invention répond au problème de fournir une attache d'un parement à la façade intérieure d'un bloc sans ajout d'un quelconque support supplémentaire tout en ménageant un vide entre la façade et le parement pour le passage de gaines et de canalisations.Thus, the present invention addresses the problem of providing a fastener of a facing to the interior facade of a block without adding any additional support while leaving a gap between the facade and the facing for the passage of ducts and doors. pipes.

Dans des modes de réalisation, au moins un des écarteurs s'emboîte à au moins un des éléments parmi la façade intérieure et le support d'isolant extérieur. L'avantage de ces modes de réalisation est qu'ils augmentent la rigidité du bloc.In embodiments, at least one of the spacers engages at least one of the inner facade and the outer insulation support. The advantage of these embodiments is that they increase the rigidity of the block.

Dans des modes de réalisation, l'emboîtement entre un écarteur et au moins un des éléments parmi la façade intérieure et le support isolant est réalisé par un tenon porté par l'écarteur, ledit tenon se trouvant contre la façade ou le support d'isolant, entre des glissières et au moins une lumière formée sur la façade ou le support d'isolant, dont une partie présente une épaisseur plus faible que la façade ou le support d'isolant, ledit tenon étant emboîté dans ladite lumière, ladite partie étant emboîtée dans une rainure de l'écarteur. Ces modes de réalisation améliorent la rigidité du bloc.In embodiments, the interlocking between a spacer and at least one of the elements of the inner face and the insulating support is made by a tenon carried by the spacer, said tenon being against the facade or the insulating support. between sliders and at least one lumen formed on the facade or insulator support, a portion of which has a smaller thickness than the facade or the insulator support, said stud being fitted into said lumen, said portion being nested in a groove of the spacer. These embodiments improve the rigidity of the block.

Dans des modes de réalisation, la façade intérieure est munie d'au moins un montant formant support d'un parement intérieur et ménageant un vide technique.In embodiments, the inner facade is provided with at least one support amount of an inner facing and providing a technical vacuum.

Dans des modes de réalisation, au moins un des éléments parmi la façade intérieure et le support d'isolant est muni d'au moins une nervure. Ces modes de réalisation ont l'avantage d'augmenter la rigidité, la planéité et la précision dimensionnelle de l'élément en éliminant les déformations pouvant se produire lors du refroidissement de l'élément après le moulage.In embodiments, at least one of the interior facade and the insulation support is provided with at least one rib. These embodiments have the advantage of increasing the rigidity, flatness and dimensional accuracy of the element by eliminating the deformations that may occur during cooling of the element after molding.

Dans des modes de réalisation, la façade intérieure et le support d'isolant ne sont pas pourvus d'un montant.In embodiments, the inner face and the insulator support are not provided with a stud.

Dans des modes de réalisation, au moins un des éléments parmi la façade intérieure et le support d'isolant est muni d'au moins un montant formant un support pour parement. Grâce à ces dispositions, le bloc peut devenir le support d'un parement intérieur.In embodiments, at least one of the interior facade and the insulation support is provided with at least one support-forming amount. for siding. Thanks to these provisions, the block can become the support of an inner facing.

Dans des modes de réalisation, le bloc objet de la présente invention comporte au moins un montant en particules de bois collées sur la façade intérieure.In embodiments, the block object of the present invention comprises at least one amount of wood particles stuck on the inner facade.

Dans des modes de réalisation, les montants sont configurés pour s'aligner et former un support continu sur une hauteur d'étage, après superposition des blocs les uns sur les autres.In embodiments, the posts are configured to align and form a continuous support on a floor height, after superimposing the blocks on each other.

Dans des modes de réalisation, l'écartement des montants correspond aux dimensions standard des plaques de parement.In embodiments, the spacing of the uprights corresponds to the standard dimensions of the facing plates.

Dans des modes de réalisation, au moins un des éléments parmi la façade intérieure et le support d'isolant est muni d'un ergot. L'avantage de ces modes de réalisation est qu'il permet un assemblage entre des blocs identiques.In embodiments, at least one of the inner facade and the insulator support is provided with a lug. The advantage of these embodiments is that it allows an assembly between identical blocks.

Dans des modes de réalisation, au moins un des écarteurs prend la forme d'un cadre évidé. Grâce à cette forme, il est possible de faire passer des barres d'armature verticales à travers l'écarteur afin d'augmenter la rigidité du mur.In embodiments, at least one of the spacers takes the form of a hollow frame. With this shape, it is possible to pass vertical rebar through the spacer to increase the rigidity of the wall.

Dans des modes de réalisation, au moins un des écarteurs est muni d'au moins une nervure sur sa face extérieure. Ces modes de réalisation ont l'avantage de permettre de placer une barre d'armature horizontale dans l'espace formé par la nervure et ainsi renforcer la rigidité du mur.In embodiments, at least one of the spacers is provided with at least one rib on its outer face. These embodiments have the advantage of allowing to place a horizontal reinforcing bar in the space formed by the rib and thus reinforce the rigidity of the wall.

Selon un second aspect, l'invention vise un procédé de constitution d'un bloc objet de la présente invention, qui comporte :

  • une étape de collage et de pressage à chaud d'une façade intérieure, d'un support d'isolant et d'au moins deux écarteurs en particules de bois,
  • une étape de positionnement de la façade intérieure en particules de bois collées et pressées à chaud,
  • une étape de solidarisation des dits écarteurs sur la façade,
  • une étape de solidarisation du support d'isolant sur lesdits écarteurs et
  • une étape de solidarisation d'une couche d'isolation sur le support d'isolant.
According to a second aspect, the invention aims at a method of constituting a block object of the present invention, which comprises:
  • a gluing and hot-pressing step of an interior facade, an insulating support and at least two wood particle spacers,
  • a step of positioning the inner face in glued and hot pressed wood particles,
  • a step of securing said spacers on the facade,
  • a step of securing the insulation support on said spacers and
  • a step of securing an insulation layer on the insulating support.

Les avantages, buts et caractéristiques particulières de ce procédé étant identiques à ceux du bloc objet de la présente invention, ils ne sont pas rappelés ici.The advantages, aims and particular characteristics of this process being identical to those of the block object of the present invention, they are not recalled here.

Selon un troisième aspect, cette invention vise un mur composé de blocs objets de la présente invention, de ferraillages verticaux entre les façades intérieures et les supports d'isolant et entre les écarteurs des blocs, de ferraillages horizontaux entre deux rangées de blocs superposées et de béton coulé entourant les ferraillages entre les façades intérieures et les supports d'isolant. Les avantages d'un tel mur est qu'il nécessite un temps de pose très faible car les blocs ne requièrent (en dehors, éventuellement, de la première rangée qui sert de jalon) aucun liant entre eux. Sa mise en oeuvre est simplifiée car son poids de pose se limite à 36kg/m2 contre 320kg/m2 pour la brique monomur et 120-150kg/m2 pour les agglomérés. La structure des blocs permet en outre, grâce à une armature en ferraillerie, une grande rigidité. Le vide d'air ménagé entre les montants de la façade intérieure facilite le travail des second-oeuvres (électriciens, plombiers,...). Finalement, un tel mur ne présente pas de ponts thermiques et bénéficie en conséquence d'une isolation renforcée.According to a third aspect, this invention is directed to a wall composed of blocks of the present invention, vertical reinforcement between the inner facades and the insulating supports and between the spacers of the blocks, horizontal reinforcement between two rows of superposed blocks and cast concrete surrounding the reinforcement between interior facades and insulation supports. The advantages of such a wall is that it requires a very low exposure time because the blocks do not require (apart, possibly, the first row which serves as a milestone) no binder between them. Its implementation is simplified because its laying weight is limited to 36kg / m 2 against 320kg / m 2 for brick monomur and 120-150kg / m 2 for agglomerates. The structure of the blocks also allows, thanks to a reinforcement frame, a high rigidity. The air gap created between the uprights of the interior facade facilitates the work of the second-works (electricians, plumbers, ...). Finally, such a wall does not have thermal bridges and consequently benefits from reinforced insulation.

DESCRIPTION D'EXEMPLES DE REALISATION DE L'INVENTIONDESCRIPTION OF EXAMPLES OF EMBODIMENT OF THE INVENTION

On note, dès à présent, que les figures ne sont pas à l'échelle.As of now, we note that the figures are not to scale.

On observe sur la figure 1, un mode de réalisation d'un bloc 10 assemblé. Ce bloc 10 est composé d'une façade intérieure en bois moulé 11 et d'un support d'isolant en bois moulé 13 tous deux reliés par quatre écarteurs en bois moulé 14 disposés entre la façade intérieure 11 et le support d'isolant 13, d'une couche d'isolant en polystyrène extrudé 15 possédant les mêmes dimensions (largeur et hauteur) que le support d'isolant en bois moulé 13 et solidaire du support d'isolant en bois moulé 13.We observe on the figure 1 , an embodiment of an assembled block 10. This block 10 is composed of a molded wooden interior facade 11 and a molded wooden insulating support 13, both connected by four molded wooden spacers 14 arranged between the interior facade 11 and the insulating support 13, an extruded polystyrene insulating layer 15 having the same dimensions (width and height) as the molded wood insulating support 13 and integral with the molded wood insulating support 13.

Dans le mode de réalisation représenté aux figures, la façade intérieure en bois moulé 11 est munie de deux montants en bois moulé 12. Dans d'autres modes de réalisation (non représentés), la façade et le support d'isolant ne sont pas pourvus d'un montant.In the embodiment shown in the figures, the molded wooden interior facade 11 is provided with two molded wooden uprights 12. In other embodiments (not shown), the facade and the insulating support are not provided. an amount.

Dans le mode de réalisation représenté aux figures, la façade intérieure en bois moulé 11 est aussi munie de cinq ergots 18 (dont quatre ergots répartis de part et d'autre de la surface et un sur la largeur de celle-ci), de huit glissières 20, de huit lumières 21 et de nervures verticales 16 ainsi que de nervures horizontales 17. On note que, dans des modes de réalisation, on ne met pas en oeuvre de nervure. En effet, en utilisant, par exemple, une presse de 2.000 tonnes, on peut réaliser des façades planes, ce qui réduit le coût de fabrication des moules et donc le coût final du produit.In the embodiment shown in the figures, the molded wood interior facade 11 is also provided with five lugs 18 (including four lugs distributed on either side of the surface and one along the width thereof), of eight slides 20, eight lights 21 and vertical ribs 16 and horizontal ribs 17. Note that in embodiments, it does not implement a rib. Indeed, by using, for example, a press of 2,000 tons, one can achieve flat facades, which reduces the cost of manufacturing molds and thus the final cost of the product.

Le support d'isolant en bois moulé 13 est muni d'un montant en bois moulé 12, de cinq ergots 18 (dont quatre répartis de part et d'autre de la surface et un sur la largeur de celle-ci), de huit glissières 20, de huit lumières 21 et de nervures verticales 16 ainsi que de nervures horizontales 17.The molded wood insulating support 13 is provided with a molded wooden upright 12, with five lugs 18 (four of which are distributed one on each side of the surface and one along the width thereof), of eight slides 20, eight lights 21 and vertical ribs 16 and horizontal ribs 17.

Les nervures 16 et 17 servent de raidisseurs des surfaces sur lesquelles elles sont disposées.The ribs 16 and 17 serve as stiffeners of the surfaces on which they are arranged.

Les écarteurs en bois moulé 14, de la forme d'un cadre évidé, sont munis de deux nervures 19 sur leur face extérieure, de quatre rainures 23 sur leur face intérieure de part et d'autre des tenons 22, d'une lumière 24 sur leur face haute et basse et de deux tenons 22. Pour assembler un tel bloc 10, on fait glisser les tenons 22 de chaque écarteur en bois moulé 14 entre deux glissières 20 de la façade intérieure en bois moulé 11 et deux glissières 20 du support d'isolant 13 de manière à ce que le tenon 22 ne puisse plus glisser davantage entre les glissières 20 de chaque façade et que les glissières 20 de la façade intérieure en bois moulé 11 et du support d'isolant en bois moulé 13 soient emboitées dans les rainures 23 de l'écarteur en bois moulé 14. La couche d'isolant en polystyrène extrudé 15 est directement appliquée sur la face extérieure du support d'isolant en bois moulé 13.The molded wooden spacers 14, in the form of a hollow frame, are provided with two ribs 19 on their outer face, four grooves 23 on their face. inner on both sides of the tenons 22, a light 24 on their upper and lower face and two pins 22. To assemble such a block 10, the tenons 22 of each molded wood spacer 14 are slid between two slides 20 of the molded wooden interior facade 11 and two slides 20 of the insulating support 13 so that the tenon 22 can not slide further between the rails 20 of each facade and the slides 20 of the inner facade molded wood 11 and molded wooden insulating support 13 are nested in the grooves 23 of the molded wooden spacer 14. The extruded polystyrene insulation layer 15 is directly applied to the outer face of the insulating support in molded wood 13.

Les montants sont configurés pour s'aligner et former un support continu sur une hauteur d'étage, après superposition des blocs les uns sur les autres. Préférentiellement, l'écartement des montants correspond aux dimensions standard des plaques de parement.The posts are configured to align and form continuous support on a floor height, after stacking the blocks on top of one another. Preferably, the spacing of the amounts corresponds to the standard dimensions of the facing plates.

On observe sur la figure 2, un mode de réalisation de la façade intérieure en bois moulé 11. La façade intérieure en bois moulé 11 est munie de deux montants en bois moulé 12, de cinq ergots 18, et de huit glissières 20, de huit lumières 21 et de nervures verticales 16 ainsi que de nervures horizontales 17.We observe on the figure 2 , an embodiment of the molded wood interior facade 11. The molded wood interior facade 11 is provided with two molded wooden uprights 12, five lugs 18, and eight rails 20, eight lights 21 and vertical ribs 16 as well as horizontal ribs 17.

On note que les ergots 18, qui constituent des moyens d'assemblage de blocs identiques, sont moulés en même temps que les faces.Note that the lugs 18, which constitute assembly means of identical blocks, are molded at the same time as the faces.

On observe sur les figures 3, 4 et 5, un mode de réalisation d'un écarteur en bois moulé 14. Les écarteurs en bois moulé 14, de la forme d'un cadre évidé, sont munis de deux nervures 19 sur leur face extérieure, de quatre rainures 23 sur leur face intérieure de part et d'autre des tenons 22 et de deux tenons 22.We observe on Figures 3, 4 and 5 , an embodiment of a molded wooden spacer 14. The molded wooden spacers 14, in the form of a hollow frame, are provided with two ribs 19 on their outer face, four grooves 23 on their inner face. on both sides of the tenons 22 and two tenons 22.

On observe, vu de haut, sur la figure 6, un mode de réalisation d'un bloc 10 assemblé tel que décrit en figure 1.We observe, seen from above, on the figure 6 , an embodiment of an assembled block 10 as described in figure 1 .

On observe sur la figure 7, un mode de réalisation d'un bloc 10 assemblé pour former un angle sortant de mur. Dans cette configuration, assemblée de façon identique au bloc 10 montré en figure 1, on étend la couche d'isolant en polystyrène extrudé 15 entre la façade intérieure en bois moulé 11 et le support d'isolant 13. Cette extension, d'épaisseur identique à la couche d'isolant en polystyrène extrudé 15 appliquée sur la face extérieure du support d'isolant 13, est appliquée de manière à couvrir totalement la face latérale de chaque écarteur en bois moulé 14 formant l'extrémité du mur. De plus, dans cette configuration, la façade intérieure en bois moulé 11 n'est munie que d'un montant en bois moulé 12 emboité, une fois le bloc 10 assemblé, dans la lumière 24 opposée de l'écarteur en bois moulé 14 auquel est déjà emboité un montant en bois moulé 12 du côté du support d'isolant en bois moulé 13.We observe on the figure 7 , an embodiment of a block 10 assembled to form an angle out of wall. In this configuration, assembled identically to block 10 shown in FIG. figure 1 the extruded polystyrene insulating layer 15 is extended between the molded wooden interior facade 11 and the insulating support 13. This extension, of identical thickness to the extruded polystyrene insulation layer 15 applied on the outside face of the insulating support 13, is applied so as to completely cover the lateral face of each molded wooden spacer 14 forming the end of the wall. In addition, in this configuration, the molded wood interior facade 11 is provided only with a molded wooden pillar 12, once the block has been assembled. 10 assembled, in the opposite light 24 of the molded wooden spacer 14 which is already fitted with a molded wooden post 12 on the side of the molded wood insulating support 13.

On observe sur la figure 8, un mode de réalisation d'un bloc 10 assemblé pour former un angle sortant de mur. Dans cette configuration, assemblée de façon identique au bloc 10 montré en figure 1 à l'exception que la couche d'isolant en polystyrène extrudé 15 mesure en largeur l'équivalent de la distance du bord avec ergot 18 au montant en bois moulé 12.We observe on the figure 8 , an embodiment of a block 10 assembled to form an angle out of wall. In this configuration, assembled identically to block 10 shown in FIG. figure 1 except that the extruded polystyrene insulating layer 15 measures in width the equivalent of the distance from the edge with pin 18 to the molded wooden upright 12.

On observe sur la figure 9, un mode de réalisation d'un bloc 10 assemblé pour former un jambage. On note que le bloc jambage comporte deux montants 12 et 24 sur la façade intérieure.We observe on the figure 9 , an embodiment of a block 10 assembled to form a jamb. Note that the jamb block has two uprights 12 and 24 on the inner facade.

On observe, sur la figure 10, des étapes d'un procédé de constitution d'un bloc objet de la présente invention, puis de constitution d'un mur avec de tels blocs. Ce mode de réalisation comporte, d'abord :

  • une étape 50 de collage et de pressage à chaud d'une façade intérieure, d'un support d'isolant et d'au moins deux, préférentiellement quatre, écarteurs en particules de bois,
  • une étape 51 de positionnement de la façade intérieure en particules de bois collées et pressées à chaud,
  • une étape 52 de solidarisation des dits écarteurs sur la façade,
  • une étape 53 de solidarisation du support d'isolant sur lesdits écarteurs et
  • une étape 54 de solidarisation d'une couche d'isolation sur la façade support.
We observe, on figure 10 , steps of a method of constituting a block object of the present invention, then forming a wall with such blocks. This embodiment comprises, firstly:
  • a step 50 of bonding and hot pressing of an inner facade, an insulating support and at least two, preferably four, spacers particles of wood,
  • a step 51 for positioning the inner face in glued and hot pressed wood particles,
  • a step 52 of securing said spacers on the facade,
  • a step 53 of securing the insulation support on said spacers and
  • a step 54 of securing an insulation layer on the support facade.

Pour constituer un mur, on encolle, d'abord, le support du mur (fondation ou plancher bas), au cours d'une étape 55. Ensuite, on colle sur le support les blocs de la première rangée, qui sert de jalon, au cours d'une étape 56. Puis, on place des ferraillages horizontaux sur la rangée de blocs qui vient d'être posée, au cours d'une étape 57. Puis, on place successivement les blocs d'une rangée supérieure, en les emboîtant dans la rangée inférieure, au cours d'une étape 58. On répète les étapes 57 et 58 jusqu'à ce que la dernière rangée de blocs soit posée. Ensuite, on place des ferraillages verticaux dans l'évidement des écarteurs, au cours d'une étape 59. Puis on coule du béton, dans l'espace entre les façades intérieures et les supports d'isolant extérieurs, au cours d'une étape 60.To form a wall, first glue the support of the wall (foundation or low floor), during a step 55. Then, we stick on the support blocks of the first row, which serves as a milestone, during a step 56. Then, horizontal reinforcement is placed on the row of blocks which has just been laid, during a step 57. Then, the blocks of an upper row are successively placed, in nesting in the lower row, in a step 58. Steps 57 and 58 are repeated until the last row of blocks is laid. Then, vertical reinforcement is placed in the recess of the spacers, during a step 59. Then concrete is poured, in the space between the inner facades and the outer insulation supports, during a step 60.

Comme on le comprend à la lecture de la description qui précède, les avantages d'un tel mur est qu'il nécessite un temps de construction très faible car les blocs ne requièrent (en dehors, éventuellement, de la première rangée qui sert de jalon) aucun liant. Sa mise en oeuvre est simplifiée car son poids de pose se limite à 36kg/m2 contre 320kg/m2 pour la brique monomur et 120-150kg/m2 pour les agglomérés. La structure des blocs permet en outre, grâce à une armature en ferraillerie, une grande rigidité. Le vide d'air entre les montants permet le passage des gaines du second-oeuvre (électriciens, plombiers,...). Finalement, un tel mur ne présente pas de ponts thermiques et bénéficie en conséquence d'une isolation renforcée.As can be understood from reading the foregoing description, the advantages of such a wall is that it requires a very short construction time because the blocks do not require (apart, possibly, the first row that serves as a milestone) no binder. Its implementation is simplified because its laying weight is limited to 36kg / m 2 against 320kg / m 2 for brick monomur and 120-150kg / m 2 for agglomerates. The structure of the blocks also allows, thanks to a reinforcement frame, a high rigidity. The air gap between the amounts allows the passage of the sheaths of the second-work (electricians, plumbers, ...). Finally, such a wall does not have thermal bridges and consequently benefits from reinforced insulation.
