Description

La présente invention concerne un bloc à bancher isolant.The present invention relates to an insulating shuttering block.

Le principe des blocs à bancher pour la réalisation de murs est bien connu. Ces blocs comportent une cavité interne et sont assemblés pour former un coffrage perdu dans lequel est coulé du béton qui assure la fonction de portance du mur.The principle of building blocks for making walls is well known. These blocks have an internal cavity and are assembled to form a lost formwork into which concrete is poured which ensures the bearing function of the wall.

Pour apporter l'isolation thermique requise tout en conservant la fonction de coffrage perdu, il a été proposé de remplacer les blocs à bancher en béton par des blocs similaires en matériau thermiquement isolant, notamment en polystyrène expansé. Après coulée du béton, on obtient alors directement un mur isolé à l'intérieur et à l'extérieur.To provide the required thermal insulation while retaining the lost formwork function, it has been proposed to replace the concrete shuttering blocks with similar blocks made of thermally insulating material, in particular expanded polystyrene. After pouring the concrete, an insulated wall is obtained directly inside and outside.

Toutefois, ces éléments à bancher isolants présentent des inconvénients. D'abord, leur légèreté fait que l'ensemble des éléments montés, avant coulée du béton, est peu stable. Ensuite, la réalisation d'un enduit extérieur sur un support en polystyrène expansé est très difficile à la fois techniquement et économiquement.However, these insulating insulating elements have drawbacks. First, their lightness means that all of the elements assembled, before pouring concrete, are not very stable. Then, the realization of an external coating on an expanded polystyrene support is very difficult both technically and economically.

Pour remédier à ce dernier inconvénient, il a été proposé dans le document FR-A-2 410 711 de munir le bloc à bancher isolant d'un revêtement extérieur fixé sur l'une ou sur les deux faces du bloc.To remedy this last drawback, it has been proposed in document FR-A-2 410 711 to provide the insulating shuttering block with an external covering fixed on one or both sides of the block.

La présente invention a aussi pour but de fournir un bloc capable d'assurer à la fois les fonctions d'élément à bancher et d'isolation thermique, sans présenter les inconvénients des éléments à bancher isolants connus.The present invention also aims to provide a block capable of ensuring both the functions of a shuttering element and thermal insulation, without having the drawbacks of known insulating shuttering elements.

Ce but est atteint au moyen d'un bloc à bancher isolant du type comportant deux plaques parallèles et espacées en matériau isolant, reliées l'une à l'autre par au moins un élément de liaison isolant, de manière à former, par l'assemblage de plusieurs blocs, un coffrage perdu dans lequel du béton peut être coulé pour réaliser un mur isolé, chaque plaque isolante étant liée par sa face externe à une planelle en matériau de construction, bloc dans lequel, conformément à l'invention, des moyens sont prévus pour permettre une liaison mécanique à travers au moins l'une des plaques isolantes entre la planelle liée à cette plaque et le béton coulé.This object is achieved by means of an insulating insulating block of the type comprising two parallel and spaced plates of insulating material, connected to each other by at least one insulating connecting element, so as to form, by the assembly of several blocks, a lost formwork into which concrete can be poured to make an insulated wall, each insulating plate being linked by its external face to a plane of building material, block in which, according to the invention, means are provided to allow a mechanical connection through at least one of the insulating plates between the plate linked to this plate and the poured concrete.

La présence des planelles en matériau de construction, c'est-à-dire notamment béton, terre cuite ou pierre, apporte plusieurs avantages.The presence of planelles in construction material, that is to say in particular concrete, terracotta or stone, brings several advantages.

D'abord, les planelles donnent un aspect extérieur traditionnel permettant la mise en oeuvre aisée d'enduits classiques. Ensuite, les planelles situées de chaque côté du bloc confèrent aux blocs à bancher empilés une grande stabilité. De plus encore, les planelles rigidifient les plaques isolantes, par exemple en polystyrène expansé, et apportent une résistance accrue à la poussée du béton coulé entre les plaques.First, the planelles give a traditional exterior appearance allowing the easy implementation of conventional plasters. Then, the planks located on each side of the block give the stacked stacking blocks great stability. In addition, the plates stiffen the insulating plates, for example made of expanded polystyrene, and provide increased resistance to the thrust of the concrete poured between the plates.

Les blocs sont empilés à sec. Ce sont les plaques qui donnent les dimensions extérieures au bloc et qui, par leur forme, permettent de façon connue un emboîtement mutuel des blocs assemblés.The blocks are stacked dry. These are the plates which give the external dimensions to the block and which, by their shape, allow in known manner a mutual nesting of the assembled blocks.

L'absence de mortier dans les joints rend nécessaire, au moins du côté extérieur du mur, la rigidification de la peau extérieure formée par les planelles, ceci pour assurer la tenue de cette peau et pour éviter une rapide dégradation de l'enduit extérieur.The absence of mortar in the joints makes it necessary, at least on the exterior side of the wall, to stiffen the exterior skin formed by the planelles, this to ensure the holding of this skin and to avoid rapid degradation of the exterior coating.

Selon l'invention, la rigidification est assurée grâce à des liaisons mécaniques entre les planelles extérieures et le béton coulé.According to the invention, the stiffening is ensured by means of mechanical connections between the external planes and the poured concrete.

Selon un mode préféré de réalisation, le blo8 comporte au moins un évidement formé dans au moins une des plaques isolantes pour permettre le passage du béton coulé, à travers cet évidement, jusqu'à la planelle liée à cette plaque.According to a preferred embodiment, the blo8 comprises at least one recess formed in at least one of the insulating plates to allow the passage of the poured concrete, through this recess, up to the plane linked to this plate.

Avantageusement, l'évidement est formé sur un des bords de la plaque isolante pour permettre au béton coulé de rejoindre, à travers cet évidement, un joint entre deux planelles. Avantageusement encore, l'évidement est formé au milieu d'un des bords horizontaux de la plaque isolante. Ainsi, les blocs étant empilés avec un décalage d'un demi-bloc à chaque rang, cet évidement se trouve en regard de l'intersection entre un joint vertical et un joint horizontal entre planelles adjacentes; à travers cet évidement, le béton assure ainsi la liaison avec trois planelles.Advantageously, the recess is formed on one of the edges of the insulating plate to allow the poured concrete to join, through this recess, a joint between two planelles. Advantageously also, the recess is formed in the middle of one of the horizontal edges of the insulating plate. Thus, the blocks being stacked with an offset of half a block at each row, this recess is located opposite the intersection between a vertical joint and a horizontal joint between adjacent planelles; through this recess, the concrete thus ensures the connection with three planelles.

En variante, au moins l'une des planelles présente, sur sa face interne, une partie saillante qui fait saillie dans l'intervalle entre les plaques isolantes en passant à travers la plaque isolante liée à cette planelle. Cette partie saillante peut être réalisée dune seule pièce avec la planelle, ou bien être réalisée sous forme d'une attache insérée lors de la fabrication de la planelle, ou bien encore être sous forme d'une nervure réalisée en béton léger, ou par des joncs en fibres, ou des matières plastiques, ... Après coulée du béton, les parties saillantes se trouvent noyées dans celui-ci assurant ainsi la solidarisation des planelles.As a variant, at least one of the planes has, on its internal face, a projecting part which projects in the interval between the insulating plates by passing through the insulating plate linked to this planelle. This projecting part can be made in one piece with the planelle, or else be produced in the form of a fastener inserted during the manufacture of the planelle, or even be in the form of a rib made of light concrete, or by rods in fibers, or plastic materials, ... After pouring the concrete, the projecting parts are embedded in it thus ensuring the joining of the planelles.

Du côté intérieur du mur, la solidarisation des planelles entre elles peut être assurée directement par un enduit en plâtre ou par des plaques de plâtre de hauteur égale à un étage et collées par plots.On the interior side of the wall, the joining of the planes to each other can be ensured directly by a plaster coating or by plasterboards of height equal to one floor and glued by studs.

D'autres particularités et avantages du bloc à bancher isolant selon l'invention ressortiront à la lecture de la description faite, ci-après, à titre indicatif mais non limitatif, en référence aux dessins annexés sur lesquels:Other features and advantages of the insulating shuttering block according to the invention will emerge on reading the description given below, by way of indication but not limitation, with reference to the appended drawings in which:

- la figure 1 est une vue en perspective d'un bloc à bancher conforme à l'invention,

  • - la figure 2 est une vue en perspective montrant plus schématiquement plusieurs blocs empilés identiques à celui de la figure 1,
  • - la figure 3 est une vue partielle en coupe de l'empilement de la figure 2, après coulée du béton, et
  • - la figure 4 est une vue en perspective d'un autre mode de réalisation d'un bloc à bancher conforme à l'invention.
FIG. 1 is a perspective view of a shuttering block according to the invention,
  • FIG. 2 is a perspective view showing more schematically several stacked blocks identical to that of FIG. 1,
  • FIG. 3 is a partial sectional view of the stack of FIG. 2, after the concrete has been poured, and
  • - Figure 4 is a perspective view of another embodiment of a formwork block according to the invention.

Le bloc 10 de la figure 1 est constitué par un élément isolant 11 en forme de double H, et par deux plaques ou planelles 21, 22 liées à l'élément isolant sur les faces extérieures de celui-ci.The block 10 of FIG. 1 is constituted by an insulating element 11 in the form of a double H, and by two plates or planes 21, 22 linked to the insulating element on the external faces of the latter.

L'élément isolant 11, par exemple en polystyrène expansé, ou autre matériau isolant thermique, est réalisé en une seule pièce. Il comprend deux plaques 12, 13 parallèles l'une à l'autre et espacées et des éléments de liaison 14, ici au nombre de deux, reliant les plaques entre elles. Chaque élément de liaison 14 s'étend perpendiculairement aux plaques 12, 13 entre celles-ci et présente une section rectangulaire en s'étendant sur une partie de la hauteur des plaques, à distance des bords inférieurs et supérieurs de celle-ci.The insulating element 11, for example made of expanded polystyrene, or other thermal insulating material, is made in one piece. He understands two plates 12, 13 parallel to each other and spaced apart and connecting elements 14, here two in number, connecting the plates together. Each connecting element 14 extends perpendicularly to the plates 12, 13 therebetween and has a rectangular section extending over a part of the height of the plates, at a distance from the lower and upper edges thereof.

Les bords verticaux des plaques 12, 13 présentent, d'un côté, des nervures 15 et, de l'autre côté, des rainures 16 de formes correspondantes, afin de permettre un emboîtement mutuel des blocs alignés horizontalement. De façon similaire, les bords horizontaux des plaques 12, 13 présentent, du côté inférieur, des nervures 17 et, du côté supérieur, des rainures 18 de formes correspondantes afin de permettre un emboîtement mutuel des blocs superposés.The vertical edges of the plates 12, 13 have, on one side, ribs 15 and, on the other side, grooves 16 of corresponding shapes, in order to allow mutual interlocking of the horizontally aligned blocks. Similarly, the horizontal edges of the plates 12, 13 have, on the lower side, ribs 17 and, on the upper side, grooves 18 of corresponding shapes in order to allow mutual interlocking of the superimposed blocks.

Les planelles 21, 22 sont en matériau de construction, par exemple en béton. Elles sont liées aux plaques 12, 13 par une liaison mécanique du type à tenon et mortaise. Des nervures verticales 19, 20 à section en queue d'aronde sont formées sur les faces extérieures des plaques 12, 13 et sont logées dans des rainures correspondantes formées dans les faces intérieures des planelles 21, 22. Des lames d'air verticales 25, 26 peuvent être formées dans les planelles 21, 22.The planes 21, 22 are made of construction material, for example concrete. They are linked to the plates 12, 13 by a mechanical connection of the tenon and mortise type. Vertical ribs 19, 20 with dovetail section are formed on the outer faces of the plates 12, 13 and are housed in corresponding grooves formed in the inner faces of the planes 21, 22. Vertical air knives 25, 26 can be formed in planelles 21, 22.

Un évidement 27 est formé dans la plaque isolante 12 adjacente à la planelle 21 destinée à être placée du côté extérieur du mur. L'évidement 27 est formé à la base de la plaque 12, à partir du bord inférieur de celle-ci et au milieu de ce bord.A recess 27 is formed in the insulating plate 12 adjacent to the plane 21 intended to be placed on the outside of the wall. The recess 27 is formed at the base of the plate 12, starting from the lower edge of the latter and in the middle of this edge.

Pour la réalisation d'un mur, les blocs 10 sont empilés, par exemple sur une hauteur d'un étage, avec les planelles 21 situées du côté extérieur et avec décalage d'un demi-bloc d'un rang sur l'autre (figure 2). L'empilement est réalisé à sec avec emboîtement mutuel des plaques isolantes, les planelles 21, 22 ne participant pas directement à l'empilement mais stabilisant celui-ci.For the construction of a wall, the blocks 10 are stacked, for example over a height of one story, with the planes 21 located on the outside and with a half-block offset from one row to the other ( figure 2). The stack is made dry with mutual interlocking of the insulating plates, the planes 21, 22 not participating directly in the stack but stabilizing the latter.

Du béton est coulé dans le coffrage formé par les éléments isolants 11 assemblés. On notera que les deux éléments de liaison 14 de chaque bloc sont disposés respectivement au quart et aux trois-quarts de la longueur du bloc. De la sorte, en combinaison avec le décalage d'un demi-bloc d'un rang sur l'autre, les éléments de liaison 14 délimitent des couloirs permettant de disposer des armatures verticales pour réaliser de véritables poteaux en béton armé. De façon similaire, la hauteur des éléments de liaison 14 étant inférieure à celle des blocs 10, il est possible de disposer des armatures horizontales à chaque rang.Concrete is poured into the formwork formed by the insulating elements 11 assembled. It will be noted that the two connecting elements 14 of each block are arranged respectively at a quarter and three-quarters of the length of the block. In this way, in combination with the offset of a half-block from one row to the other, the connecting elements 14 delimit corridors making it possible to have vertical reinforcements to make real reinforced concrete posts. Similarly, the height of the connecting elements 14 being less than that of the blocks 10, it is possible to have horizontal reinforcements at each row.

Les évidements 27 offrent au béton de remplissage des passages jusqu'aux planelles extérieures 21 de manière à former des tenons en béton 28 qui bloquent les planelles 21 et les solidarisent avec la paroi en béton 29 (figure 3). La disposition des évidements 27 à la base et au milieu des plaques 12 permet l'établissement d'une liaison entre la paroi en béton 29 et l'intersection d'un joint horizontal avec un joint vertical entre planelles 21. De la sorte, chaque planelle 21 est fixée en trois points.The recesses 27 provide the filling concrete with passages up to the external planes 21 so as to form concrete studs 28 which block the planes 21 and join them with the concrete wall 29 (FIG. 3). The arrangement of the recesses 27 at the base and in the middle of the plates 12 allows the establishment of a connection between the concrete wall 29 and the intersection of a horizontal joint with a vertical joint between planes 21. In this way, each plane 21 is fixed at three points.

Les dimensions des évidements 27, la largeur de l'intervalle entre plaques 12, 13 et l'épaisseur de la plaque 12 sont choisies en sorte que le béton coulé puisse atteindre les planelles 21 sur toute la hauteur de l'empilement, y compris pour le rang supérieur. A titre indicatif, il est souhaitable à cet effet de limiter l'épaisseur de la plaque isolante extérieure 12 à quelques cm, de préférence au plus 5 cm (par exemple 4 cm), et de choisir pour l'intervalle entre les plaques 11 et 12 une valeur de préférence supérieure à 10 cm, par exemple 14 cm. L'évidement 27 a une hauteur et une largeur de quelques cm, par exemple d'environ 4 à 6 cm. Comme le montre la figure 3, le bord supérieur de l'évidement 27 se raccorde par un arrondi avec la face interne de la plaque 12 et est incliné vers l'extérieur, de manière à faciliter le passage du béton.The dimensions of the recesses 27, the width of the gap between plates 12, 13 and the thickness of the plate 12 are chosen so that the poured concrete can reach the planes 21 over the entire height of the stack, including for the top row. As an indication, it is desirable for this purpose to limit the thickness of the outer insulating plate 12 to a few cm, preferably at most 5 cm (for example 4 cm), and to choose for the interval between the plates 11 and 12 a value preferably greater than 10 cm, for example 14 cm. The recess 27 has a height and a width of a few cm, for example around 4 to 6 cm. As shown in Figure 3, the upper edge of the recess 27 is connected by a rounded with the inner face of the plate 12 and is inclined outward, so as to facilitate the passage of the concrete.

Grâce aux tenons de béton 28, les planelles 21 constituent une peau en béton rigide sur laquelle un enduit traditionnel peut être mis en place. Du côté intérieur du mur, la solidarisation des planelles intérieures 22 est assurée directement par un enduit en plâtre ou par des plaques de plâtre de hauteur d'un étage collées par plots. Les liaisons formées par les tenons 28 constituent des petits ponts thermiques mais n'existent que du coté extérieur, la continuité de l'isolation étant assurée par les plaques intérieures 13 dont l'épaisseur peut être supérieure à celle des plaques extérieures 12. La partie externe de l'isolant assure surtout la correction des ponts thermiques au droit des points singuliers tels que planchers et refends.Thanks to the concrete posts 28, the planes 21 constitute a rigid concrete skin on which a traditional coating can be put in place. On the interior side of the wall, the interior planes 22 are secured directly by a plaster coating or by plasterboards one storey high, bonded by studs. The connections formed by the tenons 28 constitute small thermal bridges but exist only on the external side, the continuity of the insulation being ensured by the internal plates 13 whose thickness may be greater than that of the external plates 12. The part external insulation insures above all the correction of thermal bridges at the point of singular points such as floors and splits.

La figure 4 illustre un autre mode de réalisation d'un bloc à bancher conforme à l'invention. Sur les figures 1 et 4, les éléments identiques portent les mêmes références.FIG. 4 illustrates another embodiment of a shuttering block according to the invention. In Figures 1 and 4, identical elements have the same references.

Ce bloc 10' se distingue du bloc 10 en ce que la planelle extérieure 21 (représentée séparée du reste du bloc) porte une partie saillante ou nervure 28' qui traverse l'évidement 27 formé dans la plaque 12 pour faire saillie dans l'intervalle entre les plaques 11 et 12. La partie saillante 28' peut être formée d'une seule pièce avec la planelle 21. De la sorte, lorsque le béton est coulé dans cet intervalle, il assure la solidarisation de la planelle extérieure avec la paroi en béton.This block 10 ′ differs from block 10 in that the outer plane 21 (shown separated from the rest of the block) carries a projecting part or rib 28 ′ which passes through the recess 27 formed in the plate 12 to protrude in the meantime between the plates 11 and 12. The protruding part 28 ′ can be formed in a single piece with the planar 21. In this way, when the concrete is poured in this interval, it secures the external planar to the wall in concrete.

Toujours en variante, la nervure 28' peut être remplacée par une attache métallique, enrobée ou non, insérée lors de la fabrication de la planelle extérieure. Il est également possible de réaliser une nervure similaire à l'aide d'un matériau isolant tel que, par exemple, du béton léger, des joncs de fibres, des matières plastiques alvéolaires, ...Still alternatively, the rib 28 ′ may be replaced by a metal fastener, coated or not, inserted during the manufacture of the outer plane. It is also possible to produce a similar rib using an insulating material such as, for example, light concrete, fiber rods, cellular plastics, etc.

Les blocs à bancher conformes à l'invention peuvent être réalisés industriellement sans difficultés particulières. L'élément isolant 11 est préfabriqué par moulage de polystyrène expansé. Ensuite, l'élément 11 peut être placé dans un moule de produit en béton pour réaliser les deux planelles par mise en place de béton dans le moule sur chaque côté de l'élément 11. Les planelles 21, 22 peuvent aussi être fabriquées indépendamment et l'assemblage avec l'élément isolant 11 réalisé à la presse.The shuttering blocks according to the invention can be produced industrially without particular difficulties. The insulating element 11 is prefabricated by molding of expanded polystyrene. Then, the element 11 can be placed in a mold of concrete product to make the two planelles by placing concrete in the mold on each side of the element 11. The planelles 21, 22 can also be manufactured independently and assembly with the insulating element 11 produced by the press.

Bien entendu, diverses modifications ou adjonctions pourront être apportées aux modes de réalisation décrits plus haut d'un bloc à bancher conforme à l'invention sans pour cela sortir du cadre de protection défini par les revendications annexées.Of course, various modifications or additions may be made to the embodiments described above of a blocking unit according to the invention without thereby departing from the protective framework defined by the appended claims.

C'est ainsi notamment que le nombre et les emplacements des évidements 27 pourront être différents de ceux indiqués plus haut.Thus, in particular, the number and the locations of the recesses 27 may be different from those indicated above.
