Patent
CA 2491098
The invention relates to a formwork element which is specially designed for the construction of walls and similar. The inventive element comprises a hollow rectangular prismatic block or body (1') which is open at the lower and upper faces thereof and which is made from expanded polystyrene foam or another similar material. The edges of the aforementioned faces are provided with numerous small rectangular prismatic projections (3) in the form of cubes which define therebetween similarly-configured housings (4), the projections on the upper face being offset in relation to those on the lower face. In this way, when the bodies are stacked such that they are offset lengthways, a tongue-and-groove connection is created therebetween, ensuring optimum stability. Numerous bodies (1') can be stacked to produce a level chamber which is closed at the inner and outer faces thereof and which can receive a mass of reinforced concrete forming the resistant element of the wall. According to the invention, the vertical reinforcements pass through the inner hollow space of the bodies (1') while the horizontal reinforcements pass through openings (6) in the smaller lateral walls (5) thereof.
L'invention concerne un élément de coffrage destiné à la construction de murs, de parois et analogues, consistant en un corps ou bloc prismatique rectangulaire (1'), creux, ouvert au niveau de sa base supérieure et inférieure, en mousse de polystyrène expansé ou analogue. L'élément de coffrage comprend une pluralité de petites protubérances prismatiques rectangulaires (3) sous forme de doigts, situées autour des bases et espacées par des cavités (4) dont la forme correspond à celle des protubérances, les protubérances de la base supérieure étant décalées par rapport à celles de la base inférieure. Lorsque l'on empile des corps de façon décalée dans la longueur, on obtient un accouplement langueté et bouveté offrant une stabilité optimale. En empilant une pluralité de corps (1'), on forme une chambre plane fermée par des faces interne et externe, pouvant recevoir une masse de béton armé qui constitue l'élément résistant du mur ou de la paroi et dont les armatures verticales traversent l'espace creux situé à l'intérieur des corps (1') et les armatures horizontales traversent des évidements (6) situés dans les parois latérales plus petites (5) des corps.
