Definitions

  • the present invention relates to the field of public works and civil engineering, in particular the production of concrete slabs with steel frames, for example for bridges and buildings, and relates to a method of securing a mass of material to a functional support.
  • the invention also relates to devices obtained by implementing this method.
  • Steel-framed concrete slabs called mixed frameworks are generally made up of steel beams and reinforcement and concrete, the whole being cased and poured on site.
  • the drawback of such a process lies in the fact that it requires a relatively long production time, the construction not being industrialized and being subjected to climatic vagaries and to the concrete hardening period which is 28 days.
  • the material used for the support profiles is generally not used to the maximum of its possibilities, after installation, the upper part of these profiles, linked to the concrete, being little stressed mechanically, while the lower part of the profile is tense.
  • the upper part of the profile is only necessary during the short period when the profile must carry the soft concrete, and constitutes a stiffening intended to prevent its spillage or buckling and serves to retain the lost formwork.
  • connection between the support profile and the reinforcement of the concrete slab is often ensured by an attached connector, fixed by welding to the support profile.
  • an attached connector fixed by welding to the support profile.
  • Such an embodiment is relatively expensive, because it requires careful welding of said connectors.
  • FR-A-2 578 276 describes a concrete construction element, in particular a floor, consisting of support beams of reinforced concrete secured to the floor itself during the casting of the latter and by cooperation with the frames of the latter.
  • This document also relates to a method of producing such a building element using a reverse casting technique followed by a reversal.
  • the beams used in this element show projecting hooks, which are only intended for the installation and maintenance of the reinforcement of the floor and not for the housing of connection parts intended for the recovery of essentially vertical forces. , this notion being essential in order to avoid shearing forces at the level of the connection between metallic supports and concrete slabs.
  • US-A-2 636 377 discloses a reinforced concrete beam requiring fixing of the transverse steels.
  • the metal beam has in its upper part an added element provided with perforations obtained by stamping.
  • GB-A-396 569 also discloses a metal profile intended to be partially embedded in a floor element and to cooperate for this purpose with reinforcing elements, the projecting part preferably extending under the floor element. .
  • DE-U-8 714 517 describes support profile elements with a T-shaped cross section and provided on their vertical core with cutouts intended to prevent a displacement of longitudinal sliding. These cutouts are only intended for the installation and the maintenance of transverse reinforcements ensuring the maintenance of the profiles against a longitudinal sliding.

  • connection between the reinforcement 1 and the sections 2 is made in the submerged part of said sections 2, which are functionally linked to the mass of the concrete 4 via the reinforcements 1.

  • Profiles 2, which are generally metal profiles, are intended to be placed on linear or point supports constituting bridges, floors or other walls, and are most often in the form of elements of a few meters or a few tens of meters long associated, individually or in number, with a concrete slab 4 a few meters wide.
  • Each support profile 2 comprises a connection part 3 in one piece with the profile 2 and provided, at regular intervals, with cutouts 5 intended to cooperate with the reinforcing elements 1 with a view to housing and / or fixing of these, while ensuring the triangulation of the profile 2 between the sole of said profile 2 and the concrete slab 4.

  • This embodiment allows a substantial reduction in the profile 2 due to the cutouts 5 and the installation of flat reinforcing elements 7 taking up precise multi-directional forces or even round reinforcing elements, of which only a part is intended for connection, the others being intended only for the transverse reinforcement of the concrete slab.
