Definitions

  • the present invention relates to a method of manufacturing concrete beams obtained by molding in a molding bench.
  • the invention also relates to an installation implementing this method and comprising at least one molding zone provided with a molding bench.
  • Concrete beams are generally reinforced concrete beams, in which case the concrete is reinforced with metal reinforcements, or prestressed concrete beams, in which case concrete is in addition, put under stress by prestressing tendons stretched during the molding phase and then relaxed after curing the concrete.
  • the molds used for the manufacture of this type of beams extend over a great length, for example from 60 to 120 meters, and are each cut into a number T of longitudinal sections, by means of spacers or spacers. formwork combs, for manufacturing a number T of beams forming a set.
  • These molds are joined in a molding bench, which has a number M of parallel molds between them, which may have different sections.
  • each molding bench allows the simultaneous realization of a number M of sets of beams, which can have different lengths and sections.
  • each mold is prepared individually and manually by one or more operators who set up the reinforcing cages and the spacers or formwork combs at locations defined according to the length of the reinforced concrete beams to be manufactured, as described for example in the publication EP-A-0 606 794 .
  • they add prestressing cables that run the full length of the molds and are pulled by a tensioning device, as described for example in the publication WO-A-97/18070 .
  • prestressed concrete beams After pouring and hardening of the concrete, the prestressing cables are released and then cut inside the molds, either with a blowtorch or by a circular saw, with all the risks and difficulties that this represents: difficult access, alteration of the mold walls, heavy soiling, danger for the operator, etc.
  • the finished beams are then demolded one by one which, added to the previous tasks, immobilizes the molding bench over a very long period of time.
  • the current manufacturing process does not allow to consider optimal management of the production tool, nor better working conditions for operators.
  • the present invention aims to overcome these disadvantages by proposing a new semi-automated or automated manufacturing process, which eliminates the difficult tasks related to the handling of heavy elements and difficult working positions, ensures accurate manufacturing of reinforcements, deportes in out of the molding molding bench the pre-molding and post-molding processing operations, thereby reducing the downtime of the molding bench, allows a high production flexibility and optimizes the overall efficiency of the manufacturing plant .
  • the invention also relates to a manufacturing facility of the type indicated in the preamble, characterized in that it comprises at least one preparation zone of at least one set of pre-assembled elements positioned relative to the other depending on each beam to be manufactured and comprising at least reinforcing cages, this preparation zone being disposed outside said molding zone, and gripping means arranged to take a single piece of said set of elements pre-assembled of said preparation zone and depositing it in the molding bench of said molding zone, before pouring the concrete.
  • the installation 10 makes it possible to manufacture reinforced concrete or prestressed concrete beams, of different sections and lengths.
  • the beams are reinforced by metal reinforcements only, while in the second case, these beams are further stressed by metal prestressing cables.
  • the Figure 1A illustrates an example of prestressed concrete beam 1, reinforced by reinforcement cages 2 and stressed by prestressing cables 3.
  • the beam 1 as illustrated has a substantially rectangular section, given by way of non-limiting example. , this section can be square, frustoconical, T or any other section suitable for molding.
  • This installation 10 makes it possible to implement a new manufacturing process in which the beams 1 are manufactured by molding in a molding bench 40 comprising several molds 41 and whose length makes it possible to manufacture in each mold 41 several beams 1, called by following a set of beams 1.
  • the prestressing cables are removed and, consequently, the stressing operation of these cables before molding and then cutting these cables after demolding.
  • the installation 10 comprises several work zones and in particular a preparation zone A of sets of pre-assembled elements 5, a molding zone B of the beams 1, an evacuation zone C of the beams 1 manufactured (cf. Fig. 2 and 3 ).
  • This installation 10, and more particularly the preparation zone A is automated and controlled by one or more controllers receiving computer data from a design office relating to the various beams 1 to be produced (length, section, number and location of the cages reinforcement 2, number of prestressing cables 3, location of form spacers 4 and anchors 6, etc.).
  • the molding zone B comprises a molding bench 40 of reduced length compared to conventional molding benches, for example 30 to 70 meters instead of 100 to 150 meters.
  • This molding bench 40 comprises several parallel molds 41 of different sections, mounted on foundations 40 '(cf. Fig. 2 and 3 ). This particular arrangement gives this molding bench 40 a very great flexibility in the production management to simultaneously produce beams 1 of sections and of different lengths.
  • the number of molds 41 may be different, as well as their section and length.
  • These molds 41 can also be adjustable in width and / or depth by means of movable walls.
  • the preparation zone A makes it possible to prepare, apart from the molding bench 40, in parallel thereto and at human height, sets of pre-assembled elements 5 extending over the entire length of this bench.
  • Each set of pre-assembled elements 5 corresponds to one of the molds 41 and comprises an arrangement of reinforcing cages 2, formwork spacers 4, anchoring pieces 6 and prestressing cables 3 determined in FIG. function of the beams 1 to manufacture.
  • This preparation zone A comprises, in the example shown, a frame machine 20 which is a standard machine for automatically manufacturing frames 2a used in the composition of the reinforcement cages 2. These frames 2a are made by folding a wire, for example in the form of a rectangle.
  • This frame machine 20 is fed by a reel 21 carrying four coils 22 of wire of different diameters, for example 6, 8, 10 and 12 mm.
  • the frame machine 20 will automatically use one or the other diameter of wire to make frames 2a of different dimensions and strength depending on the beams 1 to be manufactured.
  • the preparation zone A comprises another reel 23 carrying three coils 24 of wire of the same diameter, for example 5 mm.
  • These three son constitute mounting frames 2b used in the composition of the frame cages 2. They are unwound simultaneously and positioned parallel, for example, in a triangle to be welded, by a welding station 25, on three sides of the frames 2a of the same reinforcement cage 2.
  • a conveyor belt 26 arranged between the frame machine 20 and the reel 23 makes it possible to bring the frames 2a towards an operator who grasps the frames 2a one after the other and presents them next to the welding machine 25 (cf. Fig. 4 ).
  • the gaps between the parallel frames 2a of the same reinforcement cage 2 are of course defined for each beam 1 to be manufactured. If the beams 1 to be manufactured have a length less than or equal to 8 meters, for example, a cage will be made of reinforcement 2 by beam 1. If their length is greater than 8 meters, two, or even three, reinforcement cages 2 per beam 1 will be realized.
  • a reinforcement cage 2 When a reinforcement cage 2 is completed, it is transferred to a preparation mat 28 by a supply chain 27 (cf. Fig. 4 ).
