Definitions

  • the present invention relates to an insulating form for the construction of concrete walls, such as a floor, a roof or a building wall.
  • He is known, particularly by EP 0 427 596 , to realize a concrete floor formwork comprising a multiplicity of mutually juxtaposed rock wool panels provided with anchoring elements projecting from their upper face, and resting by their underside on a formwork table made of wood panels .
  • a concrete slab is poured on the insulating panels by embedding the anchoring elements to secure the insulating panels to concrete after hardening.
  • the formwork table is then removed.
  • EP 1 215 346 describes a floor including in particular a succession of metal profiles nested in each other and each lined with insulation blocks, the thermal insulation being completed by an air gap between the bottom of the profile and the insulation block.
  • a wire mesh is fixed on the profiles, and a concrete slab is poured on the whole. The insulation is separated from the concrete by the air gap and it is the metal profile that is anchored to the concrete, creating thermal bridges harmful to the thermal insulation of the floor.
  • the floor described in EP 1 215 346 may in particular constitute a collaborating floor, that is to say a floor in which the formwork remains permanently and brings him, once built, the mechanical properties in traction and bending of its metal components, such as galvanized steel or not.
  • the purpose of the present invention is therefore to provide a profile, an insulating panel and a formwork incorporating them, overcoming the drawbacks of the systems of the prior art and allowing in particular to build concrete walls without creating bridges thermal.
  • a first object of the present invention is constituted by a formwork for a concrete wall comprising a plurality of juxtaposed insulating material panels provided with anchoring elements projecting from a first main face, and a formwork support rigid covering the opposite main face of the panels, formed by metal profiles each defining the bottom and the two sides of a channel which is filled by at least one insulating panel, the thickness of the latter being greater than the height of the profile, the profiles being mutually positioned side by side by the cooperation of flanges formed on both sides of the channel and housed in slot-shaped recesses of appropriate width (in the direction of the thickness of the panels) formed in a flank insulating panels.
  • a second object of the invention is constituted by a module for producing a formwork for a concrete wall, comprising a profile and at least one insulating panel as defined above, the channel of the profile being filled by the panel or panels insulators and a flange of the profile being housed in the recesses in the form of notches.
  • a third object of the invention is constituted by a building wall comprising a formwork as defined above and a cast concrete slab on the first face. main insulating panels and embedding said anchoring elements.
  • This concrete wall may in particular be used for the realization of a floor, a roof or an outer or inner wall.
  • the invention still further objects a metal profile and an insulating panel suitable to be part of the formwork mentioned above.
  • Such an insulating panel has in one of its flanks a longitudinal recess in the form of a notch, the opposite flank being substantially flat or also having a longitudinal slot-shaped recess.
  • the profile 1 comprises a substantially planar central zone 2 and two wings 3 and 4 extending substantially perpendicular to the plane of the central zone 2, the latter and the wings 3 and 4 respectively forming the bottom and the sides of a channel.
  • the central area 2 is for example provided with longitudinal ribs 5, 5 'and 5' 'having stiffening and aesthetic effects.
  • the central area 2 is provided with perforations intended to promote the acoustic absorption action of the insulation.
  • the thickness of the section 1 is chosen so as to preserve its rigidity despite the presence of the perforations, these being moreover preferably disposed on only part of the central zone 2, in particular on some of the longitudinal bands defined by the ribs 5. , 5 'and 5 ".
  • a first flange 3 of the profile 1 has a height less than the width of the profile 1 and is connected at its end to a first rim 6 extending substantially in a plane parallel to the plane of the central strip 2, and turned towards the second wing 4.
  • An elbow connects the first flange 6 to a return 7 turned away from the second flange 4, further from the plane of the central area 2 than the first flange 6.
  • the return 7 is shown as being parallel to the flange 6, but, according to an advantageous variant, it forms with the latter an acute angle of about 15 ° for example.
  • the flange 6 is folded according to a V-shaped profile 8 whose tip is directed downwards.
  • the second core 4 is connected at its end to a second flange 9 extending substantially in a plane parallel to the plane of the central zone 2, and turned away from the first one.
  • wing 3 has a V-shaped profile 10 identical to that of the first flange.
  • the profile 1 is metallic and preferably made of galvanized steel, which makes it possible to provide good corrosion resistance to the assembly.
  • the outer face which will remain apparent thus has an aesthetic appearance, not necessarily requiring additional decoration, depending on the final use of the wall.
  • FIG. 2 shows how to use the profiles according to the invention to produce a formwork according to the invention, and then a concrete wall according to the invention, such as a floor as shown in FIG.
  • FIG. 2 shows a first profile 1 identical to that described in FIG. 1, as well as a profile 20 identical to profile 1 and comprising in particular a second flange 24 and a second flange 29 identical to flange 4 and flange 9. .
  • a first insulating material panel I1 is introduced inside the section 1, the height (the thickness) of the panel I1 being greater than the height of the first profile 1.
  • one of the sides of the panel I1 has been cut horizontally at the height of the first 6.
  • the panel I1 is placed in the profile 1 so that the first edge 6 of the profile 1 is fully inserted into the notch of the panel I1.
  • the opposite flank may be substantially flat, or have a similar notch so as to allow the insertion of the panel in the section indifferently in one direction or the other.
  • Several panels such as I1 may be aligned in a contiguous manner along the length of the profile 1, depending on the respective lengths of the profile and the panels.
  • the panels I1 and I2 can be any rigid insulating panels as defined in (to be completed), including mineral wool panels such as rock wool or glass wool, or panels of cellular plastic such as polystyrene or polyurethane. More particularly, they may be stone wool whose density is not uniform in the thickness of the panels and is higher in an area adjacent to their upper face, facing away from the central areas 2, 22, only on the rest of their thickness.
  • the panels I1 and I2 have on their upper face integrated anchoring elements E1, E1 ', E2, E2'. These anchoring elements are, for example, made of spiral metal springs. The quantity of the anchoring elements depends on various parameters including the width of the panels I1 and 12.
  • the profiles 1 and 20 are then assembled as follows.
  • the second flange 29 of the second profile 20 is inserted obliquely into the acute dihedral formed by the first flange 6 and the return 7 of the first section 1, then the profile 20 is rotated so as to bring the flange 29 resting on the flange 6
  • the wings and flanges are dimensioned so that the V-shaped profiles 8 and 30 of the flanges 6 and 29 of the profiles 1 and 20 fit into one another while the flanges 3 and 24 are mutually contiguous and that the central beaches 2 and 22 extend substantially in the same plane.
  • V-shaped profiles 8 and 30 then cooperate to block any relative translational movement of the sections 1, 20 in a plane parallel to that of the central areas 2 and 22, while the flange 29 is immobilized perpendicularly to this plane in the housing formed by flange 6 and return 7.
  • rock wool panels I1 and I2 then form a continuous layer above the sections 1 and 20, thus eliminating any possibility of creating thermal bridges.
  • a metal mesh T is then placed on unrepresented shims, advantageously made of plastics material, which can be integral with the anchoring elements E1, E1 ', E2, E2'. as described in FR 2 624 154 A , or independent thereof, these shims resting on the panels I1 and I2 and now the lattice spaced apart from the anchoring elements and at a distance of about 3 cm from the surface of the panels.
  • These wedges are preferably of great length to distribute the weight of people who circulate on the mesh during handling and thus avoid damaging the surface of the panels I1, I2.
  • the function of the anchoring elements E1, E1 ', E2, E2' is to allow a solid connection between the concrete and the panels I1 and I2.
  • the metal formwork according to the invention rests before pouring concrete on supports such as props that will be removed after hardening, the formwork then being suspended from the concrete slab through the anchoring elements.
  • the invention makes it possible to reduce the number of these struts, leading to an additional saving. It suffices to have 3 stays between two beams of the floor 6 meters apart, while 6 to 10 struts must be aligned at the same distance in the existing technique. The number of struts is further decreased, 1 strut for one spacing of 6 meters, when the two ends of each section respectively rely on two adjacent beams, either directly or indirectly, for example by means of brackets fixed to the beams.
