Definitions

  • the subject of the present invention is a system of metallic reinforcement connecting between two parts of concrete work, according to the preamble of claim 1.
  • reinforced concrete structures generally require their realization in several parts which are formwork successively.
  • a first solution consists in piercing the formwork and passing it through the connecting reinforcement. This solution has the disadvantage of degrading the formwork and making formwork long and difficult.
  • Another solution consists in folding up reinforcing pieces along the formwork, during the first concreting phase, then after formwork removal, broaching the concrete, in order to release and straighten them. This work is long and presents many uncertainties as to the quality of the result obtained.
  • Another possibility is to include part of the reinforcing pieces in bodies of rigid but brittle material, such as foam of synthetic material or a chipboard of sawdust.
  • the reinforcing pieces are bent so as to have an L-shaped profile.
  • One of the branches of the L is embedded in a layer of synthetic material in the state liquid, which, upon drying, hardens while remaining brittle, ensuring excellent relative strength of the various component parts of the frame.
  • This piece of synthetic material is then positioned inside the formwork of the first part of the work in the connection zone between the two parts of the work, so that the branches protruding from the piece of synthetic material protrude at inside the first formwork and are trapped in the first part of the structure after pouring the concrete.
  • branches are then unfolded so as to be brought in the extension of the branches embedded in the concrete of the first part of the structure.
  • Formwork and reinforcement are then carried out on the second part of the structure which, after pouring the concrete, is firmly connected to the first part of the structure by the metal reinforcement pieces and by its inclusion inside the first part of the work at the level of the volume initially occupied by the synthetic material.
  • the present invention aims to make this operation easier and faster.
  • the wall of the layer of friable material in contact with the concrete of the first part of the work is covered with at least one strip or the like projecting from the layer of friable material. so as to remain accessible at the visible face thereof after formwork removal from the first part of the structure.
  • This arrangement allows, by a traction exerted on an accessible end of the strip, to tear the friable material and to initiate its detachment from the concrete, which provides an appreciable time saving for the release of the reinforcing parts.
  • the strips are of width adapted to the panel and the reinforcements used, and can be solid, perforated, in the form of a ribbon, mesh, net, cord. They can be made of different materials, such as natural or synthetic textile, synthetic material, metal, etc.
  • each connecting element Depending on the dimensions and the shape of each connecting element, it is possible to provide a single central strip, or several strips arranged on either side of the reinforcing pieces and between them.
  • the strips arranged on either side of the reinforcing pieces are formed by L or U profiles, one wing of which covers part of the large face of the layer of friable material, one of which is a wing. covers a small side face of this layer and the last wing of which in the case of a U-shaped section covers part of the other large side face.
  • This arrangement has the advantage of making it possible to tear off suddenly on the lateral parts of friable material. When these parts have been torn off the central area is easy to remove, since it has little adhesion to the concrete.
  • the strips or profiles can have a specific color facilitating the identification of the various reinforcement models used on the same work.
  • each strip covering all or part of the wall of friable material in contact with the concrete of the first part of the work is impregnated with a setting retardant adjuvant.
  • Figure 1 shows a connecting element (2).
  • This element comprises a layer (3) of rigid but brittle synthetic foam, of trapezoidal section.
  • each frame part (4) comprises a central part (5) in a U extended by two branches (6) bent at 90 °.
  • the two branches (6) are embedded in the layer of friable material (3) and the central U-shaped part (5) of each piece of reinforcement projects from the large face of the layer of friable material (3).
  • This layer of friable material (3) is covered on its large face, from which the parts (5) of the reinforcing pieces project, by a strip (7) extending over its entire length and projecting from at least one of its ends.
  • the connecting element (2) is positioned in a known manner inside the formwork of the first wall, the main thing being that one end (8) of the strip (7) is accessible after formwork removal.
  • Figure 2 shows a wall (9) constituting the first part of the work after formwork.
  • the friable material (3) is removed which releases the branches (6) from the reinforcing pieces (4).
  • these branches (6) are unfolded for positioning within the formwork of a second perpendicular wall.
  • the connecting element (2) is only equipped with a central strip (7).
  • the element (13) comprises a layer of friable material (3), from which protrude pieces of reinforcement constituted by pins (14) in the form of C.
  • FIGS 7 to 10 show four embodiments of bands that can be used. These bands are constituted respectively by an openwork ribbon (17) shown in Figure 7, a mesh (18) shown in Figure 8, a net (19) shown in Figure 9 and a cord (20) shown in Figure 10 .
  • each lateral part of the layer of friable material (3) is equipped with an L-shaped profile (22), the wing (23) of which covers the large face thereof. facing the first part of the structure and the wing (24) of which covers a small lateral face thereof.
  • each lateral part of the layer of friable material (3) is equipped with a U-shaped profile (25), the core (26) of which covers a small lateral face of it. ci and the two wings (27) and (28) of which cover part of the large faces thereof facing respectively towards the first part of the structure and on the opposite side.
  • Figures 13 and 14 show arrangements corresponding respectively to those of Figures 11 and 12, but in which the profiles (22) and (25) have small returns (29) facing inwardly of the layer of friable material. These returns produce a local weakening of the friable material section, making it easier to tear off the latter.
  • FIG. 15 shows in perspective an embodiment of an element comprising lateral profiles (22, 25) and end profiles (30).
  • bands in the form of ribbons or profiles can be made of different materials such as synthetic material, metal, natural or artificial textile, etc. As long as the material used is sufficiently porous, and if this is of interest in 'envisaged application, it can be soaked with an adjuvant forming retarder allowing, after washing the concrete, obtaining a rough surface.
  • the invention brings a great improvement to the existing technique by providing a connection system between two parts of the concrete structure, the implementation of which on site is simple and rapid.
