  • the clips 252 are thus retained by the profile and cannot be released from the latter due to the spacing of the two branches.
  • the installation comprises, following the manufacturing area 16, a stapling bench 258 described with reference to FIGS. 22 to 25.
  • the bench 258 comprises a frame formed by a number of feet 260 which support a table horizontal formed by five parallel sections 262 1 , ..., 262 5 , suitable for successively receiving an insulating plate 250 and a concrete element, for example a pre-slab 248 coming from the manufacturing area and incorporating sections of stapling as described above.
  • the stapling bench 258 also includes a movable carriage 264, movable longitudinally between the legs -260 and under the table of the bench.
  • This carriage 264 supports four staplers 266 1 , 266 2 , 266 3 and 266 4 each movable in the corridor formed between two adjacent sections forming the table of the bench.
  • the distance between the different staplers strictly corresponds to the distance between the profiles previously embedded in the pre-slab 248.
  • These staplers are advantageously pneumatic staplers controlled from a pressure source 268 carried by the carriage 264.
  • the staplers introduce, from place to place, through the insulating plate 250, staples 252 which will be housed in the different profiles 228, according to the principle described above with reference in Figure 20.
  • an adjustable stop beam 270 forming a reference support.
  • This stop beam which extends horizontally in the longitudinal direction of the table is adjustable in position_with a flywheel 272 and a locking handle 274.
  • the bench also supports a saw 280 movable longitudinally on the bench and suitable for cutting the insulating plate according to the desired width.
  • the saw 280 comprises a bracket 282 movable along the bench and a saw block 284 adjustable horizontally in position relative to the bracket. This saw block supports a circular saw 286 arranged vertically and in the longitudinal direction of the stapling bench.
  • the tracing means described above are used to materialize on a table, generally situated in the extension of the production bench, the contours of the concrete elements, in particular of the slabs, in front receive an insulating plate.
  • the table plate iso-ing the standard dimensions (eg 2.50 meters by 0.50 meters) or cut to match the expected size of the floor slabs.
  • the tracing member is then piloted to deposit glue, either in the form of a continuous net, or in the form of studs, at locations determined according to a defined program.
  • the carriage 58 of the member 48 shown in Figure 4 will advantageously include another nozzle provided specifically for spraying the glue.
  • the adhesive Once the adhesive has been deposited on the insulation plate, it is then centered and placed, for example by means of a traveling crane, the pre-slab on the insulation plates already glued.
  • the natural pressure due to the self-weight of the pre-slab ensures the tightening of the adhesive.
  • the installation as described above makes it possible to carry out the following sequence of operations: setting up and then tensioning the prestressing reinforcements; tracing of the locations of the walls from molds; installation of the vertical contours of the molds as well as any reservations; distribution and vibration of concrete in molds; notching of concrete still fresh; heating of the bench to harden the concrete; loosening of the tension of the reinforcements; shearing of reinforcements in the intervals between the cast elements; and possible installation of insulating plates on the underside of the elements.
  • the tracing can be carried out before the reinforcement is tensioned.
  • the central unit can be used to manage the stock of manufactured elements, that is to say to schedule the elements according to each site or each customer and the sequence of use of the elements.
