Description

Clé d’assemblage et blocs à construire coffrant en polystyrène expansé (PSE) à haute densité.Assembly key and formwork building blocks in high-density expanded polystyrene (EPS).

La présente invention concerne des blocs à construire coffrant réalisés en PSE haute densité, au moins 20 kilogrammes par mètre cube, et destinés à la réalisation de bâtiments passifs et BBC. Ils se déclinent en vingt-cinq blocs distincts principaux, reliés entre eux par une clé permettant l’assemblage des blocs ainsi que le blocage desdits blocs le long de leur partie coffrante. Selon des plans types, ils permettent d’édifier toute construction basée sur une structure poteaux poutres, sans chute ou perte de matière lors de l’assemblage sur chantier.The present invention relates to formwork building blocks made of high-density EPS, at least 20 kilograms per cubic meter, and intended for the construction of passive and BBC buildings. They come in twenty-five separate main blocks, linked together by a key allowing the assembly of the blocks as well as the blocking of said blocks along their formwork part. According to standard plans, they make it possible to build any construction based on a post-beam structure, without falling or loss of material during assembly on site.

Les blocs sont réalisés par découpe au fil chaud dans des éléments de matière première pleine et de grande taille, généralement 1200X1200X6000 millimètres. Les blocs sont déclinés en vingt-cinq éléments principaux, contenant un ou deux évidements, ayant des longueurs et hauteurs différentes. Les évidements sont destinés à recevoir la structure porteuse du bâtiment. La structure porteuse peut être composée d’éléments liquides durcissables et d’armatures métalliques (béton armé) ou d’éléments solides, bois ou aciers.blocks are made by hot wire cutting in solid and large raw material elements, generally 1200X1200X6000 millimeters. The blocks are declined in twenty-five main elements, containing one or two recesses, having different lengths and heights. The recesses are intended to receive the load-bearing structure of the building. The load-bearing structure can be composed of hardenable liquid elements and metal reinforcements (reinforced concrete) or of solid elements, wood or steel.

Les découpes d’assemblage et les évidements sont également réalisés lors de la découpe du bloc au fil chaud. Les découpes latérales d’assemblage sont en demi profil femelle de la clé à trait de Jupiter . Les évidements sont disposés aux extrémités droite, et, ou gauche, selon le bloc, et traversent de bas en haut les blocs, La découpe de l’évidement est réalisée à partir du centre de l’épaisseur du bloc à partir de l’axe de la découpe d’assemblage (e) , le fil pénètre à l’intérieur du bloc, réalise l’évidement et ressort par son passage d’entrée, cela crée donc une faiblesse mécanique dans le bloc tout le long de la partie latérale de celui-ci, en l’état le bloc ne pourrait contenir le béton armé lors de son coulage en phase liquide.Assembly cutouts and recesses are also made when cutting the block with a hot wire. The side assembly cutouts are in the female half profile of the Jupiter line key . The recesses are arranged at the right, and, or left ends, depending on the block, and cross the blocks from bottom to top, The cutout of the recess is made from the center of the thickness of the block from the axis assembly cutout (e) , the wire penetrates inside the block, makes the recess and comes out through its entry passage, this therefore creates a mechanical weakness in the block all along the lateral part of the latter, in the state the block could not contain the reinforced concrete during its pouring in the liquid phase.

Pour pouvoir assembler les blocs côte à côte, une clé à trait de Jupiter vient se placer entre chaque bloc. La clé est l’élément essentiel, elle permet de serrer les blocs les uns aux autres et ferme la ligne de découpe de l’évidement, rendant impossible l’éclatement du bloc par la poussée du béton encore liquide, sans déformer le bloc sur ses faces intérieures et extérieures.To be able to assemble the blocks side by side, a key with Jupiter stroke comes between each block. The key is the essential element, it allows the blocks to be clamped together and closes the cutting line of the recess, making it impossible for the block to burst by the pressure of the still liquid concrete, without deforming the block on its sides. interior and exterior faces.

Pour permettre l’alignement vertical des rangées de blocs , deux rainures parallèles sont réalisées sur les faces inférieures et supérieures des blocs (r). Les blocs sont ainsi symétriquement identiques sur leur face droite et gauche ainsi que sur leur face haute et basse. Un guide sous la forme d’une réglette (c) d’épaisseur égale à l’épaisseur de la rainure et de hauteur égale à deux fois la hauteur de la rainure vient se placer dans la rainure, elle cale ainsi le bloc supérieur (b).To allow vertical alignment of rows of blocks , two parallel grooves are made on the lower and upper faces of the blocks (r). The blocks are thus symmetrically identical on their right and left side as well as on their top and bottom side. A guide in the form of a strip (c) of thickness equal to the thickness of the groove and of height equal to twice the height of the groove is placed in the groove, it thus wedges the upper block (b ).

Pour limiter la quantité de modèles de blocs, les deux faces opposées sont symétriques et permettent de tourner le bloc selon les besoins, de droite et de gauche pour les alignements de poteaux et de haut vers le bas pour les angles de mur.To limit the amount of block patterns, the two opposing faces are symmetrical and allow the block to be rotated as needed, right and left for column alignments and up and down for wall angles.

A partir d’un plan de bâtiment donné, un calepinage est réalisé, déterminant la quantité des différents blocs nécessaires, ainsi l’assemblage des blocs s’adapte parfaitement au besoin du chantier sans coupe à réaliser et sans perte de matière, cela réduit considérablement la production de déchets.From a given building plan, a layout is carried out, determining the quantity of the various blocks necessary, thus the assembly of the blocks adapts perfectly to the needs of the site without cutting to be carried out and without loss of material, this considerably reduces the production of waste.
