Definitions

  • the invention relates to the construction of buildings and more particularly to a device for the connection of prefabricated structures.
  • An object of the invention is a means for limiting the time required for setting up the connection device between the prefabricated structures.
  • This method makes it possible to simply position, in adjacent recesses and opposite one another, prefabricated structures to connect together moving parts whose maximum spacing is determined simply by the means of limitation of the spacing of the points of assembly.
  • the mobility of the moving parts relative to each other means at least a relative mobility of the moving parts relative to each other to reduce when necessary the overall width of the device.
  • the relative mobility of the moving parts relative to each other is such that moving parts arranged to be able to penetrate into one of the borders, that is to say the rectilinear edge of one of the prefabricated structures, can come closer to other movable parts arranged to penetrate the other adjacent edges, that is to say the straight edge of the other prefabricated structures.
  • This relative approximation of the moving parts makes it possible to facilitate the positioning of the device between the borders of the structures since when some of the moving parts abut an object in a border, for example against a bottom of a border or a rod of reinforcement placed in the border, this mobile part can then retract at least in the direction of the width of the device, which amounts to locally reduce the overall width of the device.
  • the connecting devices according to the invention are arranged to be able to be positioned by sliding between the adjacent rectilinear recessed edges while a general direction of the device extends parallel to the borders and between these edges placed in a screw position. to screw.
  • the general direction of the device is the direction in which the length of the device extends (in the case of a deployable device, the length is measured when the device is deployed).
  • the method according to the invention allows a saving of time for the assembly of prefabricated structures. Indeed, during the relative positioning of the structures to be assembled, the operator does not have to worry about the positioning of the connecting device of these structures, it can thus save time and precision in the relative positioning of the structures. Moreover, since the parts of the connecting device intended to penetrate at least partially into the recesses of the structures are movable relative to each other, the connecting device has a deformable character at its mobile parts which facilitates its positioning between the structures to be assembled. Due to this relative mobility of the moving parts, the connecting device has less tendency to lock when inserted between the structures.
  • the invention also relates to a connection device for implementing the method according to the invention.
  • the spacing limitation means are such that when the areas of the cable, connected to the limiting means, are spaced apart as much as possible from each other, this cable remains distended between its first and second ends.
  • stretched between its ends means that the cable can not be stretched from one end to the other between its ends.
  • the maximum spacing allowed by the spacer limiting means is such that the cable forms a plurality of loops disposed along the cable.
  • the loops formed by the cable distributed along its length in association with the limiting means maintaining these loops allow to introduce the loops inside the recesses of the adjacent rectilinear edges without the risk that these loops disappear by pulling the cable during its introduction.
  • a binder is introduced into these recesses and, thanks to the loops of the cable, an armature is formed surrounded by the binder which extends between the prefabricated structures and inside their adjacent recesses.
  • the connecting device according to the invention is particularly easy to implement because the flexibility of the cable allows the elastic deformation of the loops during the introduction of the device in the adjacent recesses of the prefabricated structures. This results in a saving of time and manpower for the establishment of the connecting device.
  • the cable is wound so as to form a spring comprising a plurality of turns, each of these turns having two loops opposite one another, these loops of the spring cable being said loops arranged for penetrate at least partially inside the hollowed edges.
  • the spring effect of the cable is provided to tighten the loops and oppose the extension of the connecting device.
  • kit comprising a connecting device according to the invention and a tool for extending the device of the invention to put it in place in recesses adjacent borders of prefabricated structures.
  • this assembly comprising two prefabricated structures and at least one connecting device according to the invention which is surrounded at least partially by a binder such as cement.
  • this assembly according to the invention is a portion of a building such as a wall, a floor or a ceiling, or a wall connected to a floor or a wall connected to a ceiling.
  • prefabricated structure means all structures made before being assembled together. Such structures are generally made of concrete but may be of various moldable materials.

This device is intended to be inserted into these recesses in an insertion direction which is parallel to these adjacent edges 5, 6 pre-positioned relative to each other.
  • Each recess of a border 5, 6 is rectilinear and extends along this border which is also rectilinear. These recesses resemble mortises, along which it is possible to slide a looped flexible cable 7 of the device 1.
  • the prefabricated structures 3, 4 are arranged in such a way that the rectilinear and adjacent recesses of the structures to be connected face each other. one of the other and are parallel to each other and oriented towards each other.
  • the cable 7 is arranged so that a straight line passing through its ends 7a, 7b extends between these recessed adjacent edges 5, 6 and along these edges, the loops 10 of the cable then enter the adjacent recesses.
  • Each of the loops 10 forms a portion of movable portion 40 of the device.
  • the connecting device 1 forms a reinforcement which after injection of binder in these same recesses effectively links the prefabricated structures 3, 4 and thus forms an integral assembly 19.
  • Each of the prefabricated structures 3 and 4 comprises two walls facing each other and interconnected by reinforcing rods or links 20. These rods 20 connecting the walls in pairs can be part of the structure. a strapping 26 linking together four parallel rods 27 as is the case on the sets 19 of the Figures 1 to 4 . Two of the four rods 27 connected with the rods 20 are taken in one of the walls of molded material (such as concrete) and the other two rods 27 are taken in the other of these walls.
  • each wall of moldable material contains a mesh 28 extending inside the wall to serve as a frame and the rods 20 extend between these parallel walls so as to keep them apart one of the other.
  • each structure has a rectilinear recessed edge through which rods 20 extend which make it possible to bind the walls of the structure 3, 4 together.
  • These rods 20 of the border form at least one alignment of rods 20 equidistant from each other.
  • These rods 20 form the bars of a kind of scale.
  • the connecting device 1 is designed to allow expansion into these adjacent recesses of the structures and this despite the presence of the rods 20.

  • the loops formed are therefore elastically deformable.
  • a first keying bar 31 is arranged between the walls of the first prefabricated structure 3.
  • This first keying bar 31 extends behind the rods 20 which connect the walls of the first structure 3 and it passes through the loops 10 of the cable which extend into the recess of this structure 3 and pass behind the rods 20.
  • a second keybar 31 is disposed between the walls of the second prefabricated structure 4. This second bar 31 extends behind the rods 20 which connect these walls of the second structure 4 and it passes through the loops 10 of the cable 7 which extend in the recess of the structure 4 and pass behind the rods 20.
  • This arrangement of the two keying bars 31 makes it possible to prohibit the exit of the loops 10 from the respective recesses of the structures 3, 4, since if it is desired to remove the loops 10, they then push the bars 31 to abut against the rods 20 of the structures 3, 4.
  • This connection has an antiseismic protection function since if the concrete breaks under the effect of an earthquake, the bars 31 of keying, preferably steel, and the cable 7 maintain a deformable link between the structures 3, 4 preventing a complete separation of these structures 3, 4.
  • the limiting means are connected to the different zones 8a, 8b, 8c of the cable so that when these areas of the cable are separated as much as possible from each other, the majority of the loops thus formed have the same shape and are arranged at regular intervals. along the cable. Ideally, as seen on figures 1 and 6 these loops 10 are spaced by the limiting means 9 so that between two rods 20 of the same row of rods 20 aligned in the recess of a given edge 5, 6, there is at least one loop 10.
  • a plurality of loops distributed in a regular pattern along the cable are formed with regular loop shapes and adjacent loops spacings which are also regular.
  • the equidistance between the adjacent loops makes it possible to have a regular penetration of the portions of loops in the recesses of the rectilinear edges 5, 6 of the prefabricated structures 3, 4.
  • the cable 7 thus elongated between its ends 7a, 7b according to a straight line passing through these ends 7a, 7b and placed between the structures 3, 4 has a part of the loops 10 which is introduced into the recess of the structure 3 while another part of these loops 10 is introduced into the other recess adjacent to the structure 4.
  • the cable 7, preferably made of steel makes it possible to form a binding reinforcement having a regular pattern.
  • the binder once solidified in the recesses, traps at least some of the loops 10 formed between the structures 3, 4 thus creating a rigid connection composite between these prefabricated structures 3, 4.
  • the limiting means 9 comprises a rigid bar 13 of shorter length than the cable, in this case its length measured between the ends of the flexible cable with which the bar is assembled is at least 20% lower, preferably at least 50% of the maximum length of the cable 7 measured between its ends 7a, 7b. The greater the difference in these lengths, the larger the loops 10.
  • assembly means 13a, 13b, 13c, 13d are arranged along the bar 13, at regular intervals, to fix the zones 8a, 8b, 8c of the cable.
  • the use of a rigid spacing limiting means such as the bar 13 makes it possible to maintain, at all times, a regular and constant separation pitch between the assembly points 12 of the assembly means 13a, 13b, 13c , 13d.
  • the cable is wound several times around the rigid bar 13 which is thus used as a cable support to limit the maximum distance between the cable areas and as a longitudinal reinforcement to stiffen the assembly between the prefabricated structures 3, 4.
  • 13 is provided so that, during the positioning of the device 1 between the structures 3, 4, the assembly means 13a, 13b, 13c are arranged in a plane located between the rods 20 and equidistant from these rods 20 in order to have a symmetrical deformation of the loops 10 placed in the recesses. This makes it possible to have a uniform depression of the loops in the opposite recesses. It is the same with the flexible links that are connected to the cable so that their links with the cable are from and other and equidistant from a plane parallel to the rods 20 and equidistant from these rods 20.
  • an assembly means can be a simple perforation 13a through the bar 13 to pass the cable 7 while spiraling around a portion of the bar 13.
  • the bar In this mode the bar can be in two parts separated in the direction of the length of the bar and between which are formed the perforations.
  • Another means of assembly may be a hook 13b fixed on the bar 13 forming a clamp for clamping a cable area 8b against the bar 13.
  • a hook can be made by cutting and stamping a shape in the bar or can to be fixed on the bar for example by welding. It is thus possible to realize these assembly means by fixing a row of hooks along the bar 13.

  • these assembly means attached to the bar 13 may be arranged in pairs, each pair of assembly means being located between two corresponding loops (as is the case for the means 13c on the figure 8 ). This avoids the rotation of the areas of the cable assembled with the bar 13 relative to this bar. Even after deformation of the cable when it is introduced into the recesses, a relatively homogeneous loop geometry is thus maintained throughout the bar.

  • These moving parts 40 are respectively assembled at different assembly points 12 extending along spacing limiting means 9 of these assembly points 12. This limits the maximum spacing between assembly points 12. It is thus possible to slide the device along a sliding axis parallel to the length of the device and to the rectilinear edges of the structures while maintaining a spacing between the assembly points and allowing, when necessary, a variation in the width of the device. so that it can continue to slide even if it stops laterally against an obstacle present in a recess of a structure.
