Abstract

The cladding is made of panels of concrete joined by metal spacers. They are assembled by distorting one end of the spacer which then locks elastically in one of the grooves (4) in the panels. The spacer is made of two metal sheets (5, 6), each with a central area (8) with angled sections (9, 10) at each end which are bent along a fold line (11) and folded over at the ends. The two sheets are placed together, forming a triangular area (15) at each end. The triangular area can be compressed to reduce the angle of the triangle for insertion in the groove, it then regains its original shape.

Description

L'invention concerne un procédé de fabrication de blocs ou de murs de parement en béton, les blocs de parement ainsl formés, et un dispositif d'assemblage pour la mise en oeuvre du procédé. The invention relates to a method for manufacturing concrete facing blocks or walls, the facing blocks thus formed, and an assembly device for implementing the method.

Les blocs de parement actuels sont entièrement en béton et ont une forme sensiblement parallélépipédique comportant des cavités allégeant l'ensemble. The current facing blocks are entirely made of concrete and have a substantially parallelepiped shape having cavities that lighten the assembly.

La présente invention vise à alléger considérablement les blocs et à en faciliter le montage. The present invention aims to considerably lighten the blocks and to facilitate assembly.

Pour atteindre ces buts, la demanderesse a eu l'idée de réaliser des blocs composites à planelles en béton Indépendantes assemblées par des moyens métalliques d'assemblage. To achieve these goals, the applicant had the idea of making composite blocks with independent concrete planks assembled by metallic assembly means.

Plus particulièrement l'invention consiste en un procédé de fabrication de blocs ou de murs de parement, caractérisé en ce qu'il consiste à assembler des planelles en béton par une pluralité d'entretoises métalliques disposées perpendiculairement auxdites planelles. More particularly, the invention consists of a method for manufacturing blocks or facing walls, characterized in that it consists in assembling concrete planes by a plurality of metal spacers arranged perpendicular to said planes.

L'invention concerne également un bloc de parement obtenu avec le procédé et se caractérise en ce qu'il est formé de deux planelles en béton assemblées par une pluralité d'entretoises métalliques disposées perpendiculairement entre les planelles. The invention also relates to a facing block obtained with the method and is characterized in that it is formed by two concrete planes assembled by a plurality of metal spacers arranged perpendicularly between the planes.

Plus particulièrement, chaque entretoise du bloc comporte une partie centrale prolongée par deux bosselages élastiques destinés chacun à coopérer avec une feuillure disposée transversalement sur une face d'une planelle. More particularly, each spacer of the block has a central part extended by two elastic bosses each intended to cooperate with a rebate arranged transversely on one face of a plane.

L'invention porte également sur les entretoises permettant d'assembler les planelles de béton selon le procédé ci-dessus. The invention also relates to spacers for assembling the concrete slabs according to the above method.

L'invention porte également sur des murs de parement composés au moins en partie de planelles assemblées au moyen des entretoises selon l'invention. The invention also relates to facing walls composed at least in part of plates assembled by means of spacers according to the invention.

On comprendra mieux l'invention à l'aide de la description qui suite faite en référence aux figures annexées suivantes:
- Figure 1: vue générale d'un bloc de parement selon l'invention,
- Figure 2 : vue générale d'une entretoise selon l'invention servant à
I'assemblage d'un bloc de parement selon la figure 1,
- Figure 3: vue générale d'un autre exemple d'utilisation de l'invention.The invention will be better understood with the aid of the description which follows, made with reference to the following appended figures:
- Figure 1: general view of a facing block according to the invention,
- Figure 2: general view of a spacer according to the invention used to
Assembling a facing block according to FIG. 1,
- Figure 3: general view of another example of use of the invention.

On se rapporte d'abord aux figures 1 et 2. We first refer to Figures 1 and 2.

Un bloc (1) de parement selon l'invention est formé de deux planelles (2a) en béton architectonique assemblées par une pluralité d'entretoises (3) métalliques. A facing block (1) according to the invention is formed by two planes (2a) of architectural concrete assembled by a plurality of metal spacers (3).

Chaque planelle comporte sur une de ses faces une pluralité de feuillures (4) à section en queue d'aronde, par exemple deux ou quatre feuillures transversales. Each planelle comprises on one of its faces a plurality of rebates (4) with a dovetail section, for example two or four transverse rebates.

Une entretoise métallique est formée de deux tôles (5,6) maintenues par exemple en leur centre par un point de soudure (7) ou par pliage-agrafage. A metal spacer is formed of two sheets (5,6) held for example in their center by a welding point (7) or by folding-stapling.

Une tôle (5) comporte une zone centrale (8) rectangulaire prolongée de part et d'autre par une zone latérale (9 ou 10) pliée autour d'une ligne de pliage (11) perpendiculaire à la direction longitudinale de l'entretoise. Chaque zone latérale (9 ou 10) est dirigée d'un même côté de la zone (8) et se termine par un retour (12 ou 13) plié de façon à être sensiblement perpendiculaire au plan principal (14) de l'entretoise ou au plan de la zone centrale (8). Les retours (12 ou 13) sont tous deux dirigés vers le plan principal (14). A sheet (5) has a rectangular central zone (8) extended on either side by a lateral zone (9 or 10) folded around a fold line (11) perpendicular to the longitudinal direction of the spacer. Each lateral zone (9 or 10) is directed on the same side of the zone (8) and ends with a return (12 or 13) folded so as to be substantially perpendicular to the main plane (14) of the spacer or in the plan of the central zone (8). The returns (12 or 13) are both directed towards the main plane (14).

La tôle (6) est identique à la tôle (5) avec une zone centrale (8'), des zones latérales (9',10') et des retours (12',13'). Les deux tôles sont placées face à face en position inversée de manière à former une entretoise avec une partie centrale plane (8,8') prolongée par deux bosselages (15) élastiques à section triangulaire dont l'angle au sommet (A) est déterminé par les dimensions des feuillures dans lesquelles ils doivent coopérer. The sheet (6) is identical to the sheet (5) with a central zone (8 '), lateral zones (9', 10 ') and returns (12', 13 '). The two sheets are placed face to face in an inverted position so as to form a spacer with a flat central part (8,8 ') extended by two elastic bosses (15) of triangular section whose angle at the top (A) is determined. by the dimensions of the rebates in which they must cooperate.

La souplesse des tôles permet de diminuer l'angle (A) par glissement relatif des retours (12,12' ou 13,13') I'un sur l'autre, et d'introduire les bosselages dans les feuillures (4). Les bosselages reprennent leur forme initiale grâce à l'élasticité des tôles et maintiennent les planelles. De préférence deux renforts longitudinaux (16) améliorent l'élasticité. The flexibility of the sheets makes it possible to reduce the angle (A) by relative sliding of the returns (12,12 'or 13,13') one on the other, and to introduce the bosses in the rebates (4). The bosses return to their initial shape thanks to the elasticity of the sheets and maintain the planelles. Preferably two longitudinal reinforcements (16) improve the elasticity.

Des variantes d'utilisation sont possibles:
- le procédé d'assemblage représenté en figure 3 permet par exemple de réaliser des murets en utilisant des planelles courantes à quatre feuillures (17) et des demiplanelles (18) à deux feuillures. Pour épouser les courbures, on utilise pour la paroi intérieure à la courbure, des planelles courantes (17), et pour la paroi extérieure plus longue, on y ajoute une demi-planelle 18). Variants of use are possible:
- The assembly process shown in Figure 3 allows for example to produce low walls using common planelles with four rebates (17) and half-planks (18) with two rebates. To match the curvatures, one uses for the interior wall with the curvature, current planelles (17), and for the longer external wall, one adds a semi-planelle 18) to it.

- on peut également coller ou visser un des bosselage (15) de l'entretoise sur une surface lisse, par exemple un mur existant ou un panneau de recouvrement, L'autre bosselage étant engagé dans la feuillure d'une planelle. Ce procédé permet de réaliser des parements sur des murs existants. - One can also glue or screw one of the bosses (15) of the spacer on a smooth surface, for example an existing wall or a cover panel, the other boss being engaged in the rebate of a plane. This process allows for facing on existing walls.

Les avantages de 1' invention sont notamment les suivants:
- la géométrie des feuillures béton permet d'assurer une bonne tenue de l'entretoise métallique,
- la géométrie de l'entretoise métallique et l'élasticité de ses deux parties extrêmes permet un contrôle de la force de blocage par le double bosselage et l'épaisseur de la tôle utilisée,
- I'épaisseur d' un muret formé de blocs selon l'invention peut être modifiée en
Jouant sur les longueurs des entretoises métal,
- la diminution du poids d'un bloc de parement est considérable,
- la liberté de mouvement des deux planelles et/ou l'utilisation de demi-planelles permet l'adaptation aux courbures,
- le prix de revient d'un bloc est diminué de façon importante,
- le concept planelle-entretoise permet une mise en oeuvre simplifiée et légère. The advantages of the invention are in particular the following:
- the geometry of the concrete rebates ensures good resistance of the metal spacer,
- the geometry of the metal spacer and the elasticity of its two end parts allows control of the blocking force by the double embossing and the thickness of the sheet used,
- the thickness of a low wall formed of blocks according to the invention can be modified in
Playing on the lengths of the metal spacers,
- the reduction in the weight of a facing block is considerable,
- the freedom of movement of the two planelles and / or the use of half-planelles allows adaptation to curvatures,
- the cost price of a block is significantly reduced,
- the planelle-spacer concept allows a simplified and light implementation.
