Definitions

  • the present invention relates to an integrated formwork wall manufacturing method for producing an exterior wall of a building.
  • This invention again, relates to a formwork wall integrated, in particular obtained by the implementation of such a method.
  • the invention relates to the field of the building industry and, more particularly, that of the manufacture of integrated formwork walls used in the context of the construction of a building for the realization of the walls of such a building.
  • Such formwork walls are usually known as pre-walls.
  • these walls take the form of a double skin and comprise, on the one hand, an inner skin to be oriented towards the interior of the building and, on the other hand, an outer skin to be oriented in the direction from outside the building.
  • These two skins are each constituted by a concrete slab and are interconnected by means of connecting means, usually constituted by metal stiffeners or the like, making it possible to make these two skins integral with one another and to ensure the immobilization one compared to the other.
  • these two skins are positioned, within the integrated form wall, facing one another, substantially parallel and at a distance from one another so as to define between them a spacing intended to be filled by a concrete poured between these skins during the implantation of this formwork wall integrated on site.
  • Such a wall has a number of drawbacks related, on the one hand, to the process of manufacturing such a wall and, on the other hand, to the elements that constitute the latter.
  • connection means are available in a mold and concrete is poured into this mold in order to produce a first concrete plate intended to constitute one of the skins. After drying of the first concrete plate, the latter is turned over and the connecting means which equip it are placed in a mold containing concrete for the production of a second concrete plate intended to constitute the second skin of the concrete. Wall. After drying of this second skin, the wall is unmolded for storage and further drying.
  • the document DE 36 09 780 describes an integrated formwork wall for the construction of an exterior wall of a building.
  • This wall has an inner skin, intended to be oriented towards the interior of the building, and constituted by a concrete plate.
  • This wall comprises, again, an outer skin, intended to be oriented towards the outside of the building, and constituted by a plate of an insulation facing, at least in part, constituted by a plate of an insulating material. or even by a juxtaposition of plates of an insulating material.
  • these skins are positioned facing each other, substantially parallel and at a distance from one another so as to define between them a spacing intended to be filled by a poured concrete between these skins.
  • This wall also includes means for connecting said inner and outer skins together, these connecting means previously equipping said outer skin and having a first end secured to the inner skin.
  • This document also describes a method for manufacturing an integrated form wall having the features of the preamble of claim 9.
  • the present invention is intended to overcome the disadvantages of integrated formwork walls of the state of the art.
  • Such an integrated formwork wall comprises a single skin (internal) concrete while the other (outer) skin is constituted by a facing plate.
  • the time of manufacture of the wall is considerably shortened, especially because of the absence of a second concrete skin (drying time of the wall divided by two).
  • the absence of a second concrete skin makes it possible, again, to avoid the use of a particularly expensive turning tool whose use presents risks for the integrated formwork wall.
  • the weight of a wall with integrated formwork according to the invention is substantially reduced compared to that of the walls of the state of the art which allows to increase (in particular to double) the loading capacity of a transport equipment (and thus reduce the cost of transport) but also to use lifting gear whose lifting capacity and dimensions are more modest compared to those essential for walls of the state of the art.
  • the use of a wall in accordance with the invention allows a substantial saving of time and a significant reduction of the costs of the insulation, because of the absence of an operation of bonding an insulator on site that requires the walls of the state of the art.
  • the fact of using a formwork wall integrated with a single concrete skin advantageously allows to reduce the amount of material (concrete) used for the manufacture of a wall thus reducing the thickness of this wall (from 12 to 16 cm against 18 to 21 cm for the walls of the state of the technical) which, for a given surface of the building on the ground, allows an increase in the usable (habitable) internal surface compared to the walls of the state of the art.
  • the present invention relates to the field of the building industry and, more particularly, that of the manufacture of integrated formwork walls used in the context of the construction of a building for the realization of the walls of such a building.

  • said inner skins 2 and outer skins 3 are positioned opposite one another 2, in a substantially parallel manner and at a certain distance one 2 of the other 3 so as to define between them a spacing 5.
  • This spacing 5 is intended to be filled by a concrete poured between these skins 2, 3 and within this spacing 5, this after the integrated form wall 1 has been put in place on site.
  • the inner skin 2 is constituted by a plate 6 of concrete while the outer skin 3 is constituted by a plate 7 of an insulation facing.
  • said facing plate 7 is designed so as to provide an insulating function (phonic and / or thermal) but not a structural function (such as a function of resistance) which is provided by the concrete slab 6 of the inner skin 2 and, also and after curing, by the concrete layer cast in the aforementioned spacing 5.
