Definitions

  • the present invention relates to an insulating shuttering block.
  • 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.
  • 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.
  • planelles in construction material, that is to say in particular concrete, terracotta or stone, brings several advantages.
  • the planelles give a traditional exterior appearance allowing the easy implementation of conventional plasters.
  • the planks located on each side of the block give the stacked stacking blocks great stability.
  • 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.
  • 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.
  • the stiffening is ensured by means of mechanical connections between the external planes and the poured concrete.
  • 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.
  • 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.
  • the recess is formed in the middle of one of the horizontal edges of the insulating plate.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the planes 21 constitute a rigid concrete skin on which a traditional coating can be put in place.
  • 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.
  • FIG. 4 illustrates another embodiment of a shuttering block according to the invention.
  • identical elements have the same references.
  • 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.
  • 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.
  • 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.
  • the number and the locations of the recesses 27 may be different from those indicated above.
