Definitions

  • the present invention relates to a structural joint for slabs of moldable material and in particular for slabs of hydraulic binder material such as concrete.
  • the invention therefore relates to a structural joint, by example in steel, intended to reinforce the edges of a material of matrix or slab, for example concrete, never taking off your shoes out of it, neither because of the joint itself, nor because of the matrix by breaking it in the vicinity of the anchor.
  • the reinforcement joint includes a male and female socket offset downward from the line median of the slab to obtain a greater matrix thickness important above the socket in order to obtain resistance increased against external stress loads.
  • the profiles are integral with the concrete slabs, thanks to the concrete iron anchors welded to the profiles.
  • a commonly used structural joint is made using of a double profile essentially in the shape of an omega whose outline the exterior of one follows the interior contour of the other.
  • the part central male joint must necessarily have a volume sufficient to allow it to be filled with the moldable material.
  • the object of the present invention is to remedy the disadvantages mentioned above by simple and effective means which will be described in more detail in the following description.
  • FIG. 1 a structural joint 10, according to the known state of the art, comprising two metal profiles arranged along the adjacent edges of two concrete slabs 20, 22.
  • the seal 10 is constituted by a profile forming a part male 12, anchored in the edge of the slab 20, and a profile forming a female part 14, anchored in the edge of the slab 22.
  • the male and female parts 12, 14 of the profiles are provided fins which extend upwards and downwards so as to marry respectively stops the upper surface and stops the surface bottom of the concrete slabs 20, 22.
  • the anchoring of profiles 12 and 14 is usually carried out at using concrete irons 16 distributed over the length of said profiles.
  • the male part 12 of the profile has a cavity 18 which must be filled with moldable material such only concrete and therefore cannot be reduced to dimension because, in this case, the concrete will be difficult to penetrate.
  • the distance "d" between the upper side 15 of the female profile 14 and the surface 23 of the concrete slab 22, is strong limited, or real risk of cracking and spalling along a line rupture 24.
  • FIG. 1 One embodiment of a joint according to the invention is shown in figure 2.
  • the structural joint 30 consists of two profiles of particular shape which fit together also as a tenon and mortise.
  • the male part 32 is produced using a sheet metal L-shaped substance whose vertical wing extends to the ridge of the upper surface of the slab 20 and whose base wing 31 is folded down to create a second lower wing 33 folded all against the first and whose end may extend beyond the vertical wing to form a heel 29 for anchoring in the concrete.
  • the female part 34 of the seal 30, is also produced at using a substantially L-shaped sheet with a vertical wing extending up to the stop of the upper surface of the slab 22 and the wing of which base 35 is folded down to create a second branch lower 37 arranged parallel to the first branch 35 while leaving between them a space 36 in which can engage the folded branches 31, 33 of the male profile 32.
  • the distance "D" between the wing of base 35 of the female profile 34 and the surface 23 of the concrete slab 22 is much greater than in Figure 1 and the mass of concrete can easily support heavy loads along the edge of the slab concrete 22.
  • This angle 38 preferably extends to the stop of the lower surface of the concrete slab 22.
  • FIG. 4 shows an equivalent embodiment according to the invention.
  • the female part 54 has an L-shaped mirror image integral with the edge of the slab of concrete 20 and the vertical wing 47 of which extends to the stop of the upper surface of this slab.
  • the base wing 55 extends towards the inside of the slab and is folded down to form a double wing 57 which extends parallel with the base wing 55 leaving a reduced space 56 between them.
  • the male part 52 is also L-shaped in image mirror and is integral with the edge of the concrete slab 22.
  • the vertical wing 58 extends to the edge of the surface upper of the slab and the base wing 51 extends outwards from the edge of the slab 22 and is provided with a heel 59 which extends towards inside the slab 22.
  • edge of one of the slabs 22 is rendered secured to a female profile 34 similar to FIG. 2.
  • the edge of the other slab 20 is made integral with a second female profile 43 arranged in image mirror relative to the first female profile 34.
  • the male part consists of a flat part independent 40 of which one end 41 can engage in the first female profile 34 and whose other end 42 can engage in the second female profile 43.
  • the upper and lower areas of the edge of the slab located on either side of the male / female part of the seal and which are fill with moldable material, are increased in thickness and guarantee optimum shear strength.
  • the new profile thus allows use in a range of different thicknesses of the slab or matrix.
  • This offset is obtained thanks to the small size of the male part of the socket consisting of a metallic part or not, compact and rigid ensuring high nesting resistance.
  • the male part being massive, thanks to the invention, there is more problems with its filling and the decrease in its bulk is done for the benefit of the upper matrix sections and lower, ensuring optimal resistance of the edges of the slabs.
