Definitions

  • the present invention relates to an interlocking element intended to complete a formwork lost from a concrete horizontal structure, particularly at the level of the connection of this structure with a vertical wall.
  • WO-A-00/31355 describes interviews in plastic form forming lost formwork and wall slim.
  • This document describes a tympanic device that allows to adjust the realization of the formwork to the dimensions the area to be covered and in particular the length of this surface.
  • the use of a tympanum is, as explained in this document, adapted to constructions in which the end of the support beams of the floors is contained in a substantially perpendicular plane to the longitudinal dimension of these beams.
  • the invention proposes a interstitial element intended to complete a lost formwork of a cast concrete horizontal structure, in particular at the connection level of this structure with a vertical wall, which consists of a tray open upwards, in thin wall, with two edges intended for its support on two parallel beams of floor, two end walls provided with means complementary overlap with each other, and a internal partitioning of stiffening and reception of concrete liquid.
  • partitioning internal includes walls perpendicular to the edges above, formed by an open U-shaped double wall downwards, delimiting transverse boxes united between them by rear partitions between the walls of each U. It is practically realized transverse beams between two interjoin support beams, which are very little spaced from each other. These beams transverse, even when cut at an angle and that they find a support on a support wall on along this bias, are rigid enough to rest correctly on this support in order to support the concrete that will be poured over the interjoists and to ensure the tightness of this support.
  • each edge of the element which is used to support it on a beam is distant from bottom of the tray of this element a height substantially equal to the thickness of the beam measured under the rim.
  • the beams are based on a structure vertical end, when one sets up the interjoist element according to the invention, the latter rests also by the bottom of his tray on the same support than that of the beams, which makes it possible to have important contact surface between this end support and this element of interjoists, and therefore favorable to a good concrete retention.
  • the modular element of interjoists represented Figures 1 and 2 affect the shape of a rectangular tray 1 with two parallel longitudinal sides with flanges 2 and 3 and two transverse sides 4 and 5 provided with means 6, 7 arranged in correspondence to overlap.
  • This will be for example a gutter such as 6 tour down and a gutter such as 7 turned towards the high.
  • the edges 2 and 3 as illustrated by the figure, serve to rest each element of interjoists on beams 24, 25 which form the reinforcement of a floor of a construction.
  • These ledges define the direction longitudinal of the element of interjoists although in this direction, for the example shown, the smaller than the transverse dimension of the element that is itself dictated by the spacing standardized beams 24 and 25.
  • the figures show that the internal space of the bin 1 is partitioned.
  • This internal partitioning, noted 8 has two types of walls, some 9 longitudinal formed of a single thickness, and the other 10 transverse formed of a double wall defining an open U towards the back or the bottom of the interjoists, this U comprising therefore 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 that remind one to smaller scale the boxes of described interjoists in the document recalled in the preamble of the present description. The presence in this case of four walls 9 defines therefore, with the three double walls 10, a set twenty compartments.
  • each compartment defined by partitioning 8 (here the interstitial element comprises twenty compartments), has surface texturing that is to say, reliefs in the form of grooves 14, either in the form of rib networks 15 or under form of fins 16, which have the effect of creating a connection between the plastic material and the concrete poured the interior such as this plastic material, essentially flammable, does not participate in the spread 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 rests also 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.
