Definitions

  • the present invention relates to a interjoist element for completing a formwork lost a horizontal concrete structure, particularly at the connection of this structure with a vertical wall.
  • An element according to the preamble of claim 1 is described in FR-A-2,600,098 .
  • the field of the invention is illustrated in particular by the document WO-A-00/31355 which describes plastic interstices forming a formwork lost and thin-walled.
  • This document describes a tympanic device that adjusts the realization of the formwork to the dimensions of the surface to be covered and in particular the length of this surface.
  • the use of a tympanum is, as explained in this document, suitable for constructions in which the end of the support beams of the floors is contained in a plane substantially perpendicular to the longitudinal dimension of these beams.
  • the support structures formed by these beams may end on walls or walls that are slanted with respect to the longitudinal direction of the beams, and in these conditions neither the eardrum nor even the interjoists described in the document. cited do not allow to achieve a surface capable of receiving a compression slab, that is to say liquid concrete.
  • the invention proposes a interjoists element intended to complete a lost formwork of a cast concrete horizontal structure, in particular at the connection of this structure with a vertical wall, which element is constituted by a tray open upwards, in thin wall, having two flanges for its support on two parallel floor beams, two end walls provided with overlapping means complementary to each other, and an internal partitioning stiffening and welcome liquid concrete.
  • the internal partitioning comprises walls perpendicular to the aforementioned edges, formed by a double U-shaped wall open towards the bottom, defining transverse boxes joined together by rear walls between the walls of Each U.
  • Virtually transverse beams are made between two support beams interjoists, which are very closely spaced from each other. These transverse beams, even when they are cut at an angle and they find a support on a support wall along this bias, are rigid enough to rest properly on this support to support the concrete that will be poured over interjoists and to ensure the tightness of this support.
  • each flange of the element which serves to support it on a beam is remote from the bottom of the tank of this element by a height substantially equal to the thickness of the beam measured under the flange.
  • the beams are based on a vertical end structure, when one sets up the interjoists element according to the invention, the latter also rests by the bottom of its tray on the same support as that of the beams. which makes it possible to have a large contact surface between this end support and this interjoistic element, and thus favorable to good retention of the concrete.
  • the modular element of interjoists shown in Figures 1 and 2 has the shape of a rectangular tray 1 with two parallel longitudinal sides provided with flanges 2 and 3 and two transverse sides 4 and 5 provided with means 6, 7 arranged in correspondence for overlap. This will be for example a gutter such as 6 turned down and a gutter such as 7 turned upwards.
  • the edges 2 and 3 as illustrated in the figure, serve to rest each interjoists element on beams 24, 25 which form the frame of a floor of a building.
  • These flanges define the longitudinal direction of the interjoister element although in this direction, for the example shown, the dimension is smaller than the transverse dimension of the element which is in turn dictated by the normalized spacing of the elements. beams 24 and 25.
  • the internal space of the tray 1 is partitioned.
  • This internal partition has two types of walls, one longitudinal 9 formed of a single thickness, and the other 10 formed of a double wall defining a U open towards the back or the bottom of the interjoists this U thus having two faces facing each other noted 11 and 12, and rear walls 13 which bring them together.
  • Tray 1 is here divided by these three double walls 10 in four transverse boxes which recall on a smaller scale the caissons interjoists described in the document recalled in the preamble of the present description. The presence in this case of four walls 9 thus defines, with the three double walls 10, a set of twenty compartments.
  • each of the compartments defined by the partitioning 8 (here the interjoin element has twenty compartments), has a surface texturing that is to say reliefs in the form of grooves 14, or in the form of networks ribs 15, or in the form of fins 16, which have the effect of creating a connection between the plastic material and the cast concrete inside such that this plastic material, essentially flammable, does not participate in the propagation of a fire.
  • an interjoists 20 are disposed between two heel joists 24 and 25, and an interjoists 21 hooked to the interjoists 20 by cooperation of the complementary means 6 and 7 described above, the latter between you being cut in half. bias in a plane 22 to be adjusted to a vertical wall 23 located in this plane.
  • This wall 23 comprises a support 23a, which is a board on which the biased end of the beams 24 and 25 is based.
  • the interjoists 21 also rests on the ledge 23a of the wall 23. the support of this and other interjoists interjoists is then extremely firm, and one can easily make a concrete casting to achieve such a compression slab.
