Definitions
- the present invention relates to a method for manufacturing concrete beams obtained by molding in a molding bench.
- the invention also relates to a installation implementing this process and comprising at least one zone of molding provided with a molding bench.
- Concrete beams are usually reinforced concrete beams, in this case the concrete is reinforced by metal reinforcements, or prestressed concrete beams, in this case, the concrete is, in addition, under stress by prestressing cables stretched during the phase molding then slackened after hardening of 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 cut each in a number T of longitudinal sections, by means of dividers or formwork combs, for the manufacture of a number T of beams forming a together.
- These molds are brought together in a molding bench, which has a number M of molds parallel to each other, which may have different sections. So, each molding bench allows the simultaneous production of an M number sets of beams, which may have different lengths and sections.
- each mold is prepared individually and manually by a or several operators who install the reinforcement 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 publication EP-A-0 606 794.
- they add cables of prestress which extend over the entire length of the molds and which are pulled by a tensioning device, as described for example in publication WO-A-97/18070.
- prestressed concrete beams After pouring and hardening concrete, the prestressing cables are released and then cut inside the mussels, either with a blowtorch or with a circular saw, with all the risks and difficulties this represents: difficult access, deterioration of the mold walls, heavy soiling, danger to the operator, etc.
- the finished beams are then unmolded one by one which, added to the previous tasks, immobilizes the bench molding over a very long period of time.
- the current manufacturing process does not allow not to consider optimal management of the production tool, nor better working conditions for operators.
- the present invention aims to overcome these drawbacks by proposing a new semi-automated or automated manufacturing process, which eliminates tasks tedious related to the handling of heavy elements and difficult work positions, guarantees precise fabrication of the frames, offset outside the molding bench preparation operations before molding and treatment after molding and this reduces the downtime of the molding bench, allows great production flexibility and optimizes the overall performance of the installation manufacturing.
- the invention also relates to a manufacturing installation of the kind indicated in the preamble, characterized in that it comprises at least one zone of preparation arranged outside said molding zone in which are prepared pre-assembled elements comprising at least the reinforcement cages entering the manufacture of said beams, these elements being positioned relative to the others at predetermined locations depending on each beam to be manufactured, said pre-assembled elements constituting at least one assembly intended to be taken in one piece by gripping means to be placed in the bench molding before pouring concrete.
- the installation 10 makes it possible to manufacture reinforced concrete or prestressed concrete beams, of sections and lengths different.
- the beams are reinforced by reinforcements metallic only, whereas in the second case, these beams are additionally placed under stress by metallic prestressing cables.
- Figure 1A illustrates a example of a prestressed concrete beam 1, reinforced by reinforcement cages 2 and stressing by prestressing cables 3.
- the beam 1 as illustrated has a substantially rectangular section, given by way of example not restrictive, this section can be square, frustoconical, T-shaped 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 the length of which makes it possible to manufacture in each mold 41 several beams 1, hereinafter called a set of beams 1.
- the prestressing cables are omitted and, consequently, the operation of stressing these cables before molding then cutting these cables after demolding.
- the installation 10 includes several work areas and in particular a preparation area 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 (see fig. 2 and 3).
- This installation 10, and more particularly the area of preparation A is automated and controlled by one or more machines receiving computer data from a design office relating to the different beams 1 to make (length, section, number and location of reinforcement cages 2, number of prestressing cables 3, location of formwork spacers 4 and anchors 6, etc.).
- the molding area B comprises a molding bench 40 of reduced length by compared to conventional molding benches, for example from 30 to 70 meters instead of 100 to 150 meters.
- This molding bench 40 comprises several parallel molds 41, of different sections, mounted on 40 'foundations (see fig. 2 and 3). This arrangement particular gives this molding bench 40 great flexibility in management of production to simultaneously realize beams 1 of sections and lengths different.
- the number of molds 41 can be different, as can their section and their 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, outside the molding bench 40, in parallel to it and at breast height, sets of pre-assembled elements 5 extending over the entire length of this molding bench 40.
- Each set of pre-assembled elements 5 corresponds to one of the molds 41 and includes a arrangement of reinforcement cages 2, formwork spacers 4, anchoring parts 6 and prestressing cables 3 determined according to the beams 1 to be manufactured.
- This preparation zone A includes, in the example shown, a frames 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 bending a metal wire, for example in the shape of a rectangle. This frame machine 20 is fed by a reel 21 carrying four bobbins 22 of wire metal with different diameters, for example 6, 8, 10 and 12 mm. By type of beams 1 to be manufactured, the frame machine 20 will automatically use one or the other diameter of metal wire to make frames 2a of dimensions and different strengths depending on the beams 1 to be manufactured.
- the preparation zone A comprises another reel 23 carrying three reels 24 of metallic wire of the same diameter, for example 5 mm.
- These three sons 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 machine 25, on three sides of the frames 2a of the same reinforcement cage 2.
- a conveyor belt 26 disposed between the frame machine 20 and the reel 23 allows the frames 2a to be brought to an operator who grasps the frames 2a one after the other and presents them next to the welding machine 25 (see fig. 4).
- the intervals between the parallel frames 2a of the same reinforcement cage 2 are indeed understood 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, we will make a cage of reinforcement 2 per beam 1. If their length is greater than 8 meters, we will realize two, or even three, reinforcement cages 2 per beam 1.
- a reinforcement cage 2 When a reinforcement cage 2 is completed, it is transferred to a mat. preparation 28 by a supply chain 27 (cf. fig. 4).
- This preparation mat 28 extends parallel over the entire length of the molding bench 40 and receives the cages of reinforcement 2 aligned one behind the other, as they are finished, and in the exact order of their intended position in the mold 41 corresponding.
- the formwork spacers 4 and the anchor pieces 6 (cf. fig. 6) are interposed between the reinforcement cages 2, their handling being for example carried out by a lifting beam (not shown) placed at the start of the preparation mat 28.
- prestressing cables 3 are threaded through reinforcement cages 2, formwork spacers 4 and parts anchor 6 over the entire length of the preparation mat 28.
- the installation of these prestressing cables 3 can be carried out either manually or semi-automatically, either automatically using a specific machine which does not not the object of the present invention.
- a set of pre-assembled elements 5 corresponding to a mold 41 determined.
- the formwork spacers 4 make it possible to delimit the beams 1 between them in the same mold 41 and for example consist of a perforated metal plate whose number of holes corresponds to the number of cables prestressing 3.
- the anchors 6 are used both for transport of said assembly 5, between the preparation A and molding B zones, and for the attachment of the prestressing cables 3 to the traction devices 50, 51 provided on the molding bench 40. They are for example made of metal combs.
- this preparation area A is designed to allow the operator to work in good ergonomic conditions, the conveyor belts 26 and preparation 28 being located at breast height, and to avoid any handling, the advancement of the reinforcement cages 2 being controlled manually by button push, without physical effort.
- the set of pre-assembled elements 5 is then routed into the mold 41 adequate, in a single operation, by specific gripping means 31 attached to the anchoring pieces 6.
- These gripping means 31 are suspended from a spreader 30, the latter being movable in translation along the three axes X, Y, Z on a traveling crane (see fig. 3 and 5).
- These gripping means 31 are arranged to lift in one piece each set of pre-assembled elements 5 in it applying tension to tension the prestressing cables 3, avoid buckling and facilitate its positioning in the mold 41 as well as the introduction of said cables prestress 3 in the traction devices 50, 51 described below.
- the bridge rolling spans the preparation A and molding B zones to allow gripping means 31 to pass easily from one to the other zone A, B and C.
- a new set of pre-assembled elements 5 can be prepared in preparation area A to garnish another mold 41.
- the prestressing cables 3 are laid in tension by traction devices, commonly called headers 50, 51, arranged at the ends of the molds 41 in suitable pits 42 provided in the foundations 40 '(cf. fig. 6A-6C).
- headers 50, 51 a fixed head 50 and a head 51 movable in rotation around a pivot 52 secured to the foundations 40 'between a rest position (cf. FIG. 6A) in which it exerts no traction on the prestressing cables 3 and a working position (see fig.
- headers 50, 51 of different width and power. Rooms anchor 6 of the sets of pre-assembled elements 5 provided at the ends making it possible to block the prestressing cables 3 in the headers 50, 51.
- These headers 50, 51 are designed to allow automatic threading of the cables prestress 3 by vertical movement from top to bottom and unthreading by a reverse movement. They are formed of parallel, vertical, 53 strips separated by intervals 54 allowing the introduction of a prestressing cable 3 by interval 54 (cf. fig. 6C). This new design saves time very important and an automation of the threading.
- prestressing cables are threaded manually and individually in through holes.
- the mobile headers 51 are set in motion each by a jack 55 of force, articulated at its two ends between a pivot 56 secured to the foundations 40 ′ and a pivot 57 secured to the header 51.
- a removable stop 58 allows limit the stroke of the movable head 51, this stop 58 being actuated by another actuator 59.
- the movable headers 51 allow partial tension of the prestressing cables 3, for example from 30 to 50% of the total tension. Setting final tension is carried out unitarily on each prestressing cable 3 at for example by means of a single-wire cylinder.
- each mold 41 is demolded into a single operation by the gripping means 31 of the lifter 30 which raises by alone holding all the beams 1 and depositing it on means of transport 60 provided in evacuation zone C.
- handling hooks are provided in the upper part of the beams 1 for hanging the means gripping 31 of said lifter 30.
- the means of transport consist, in the example shown, of a carriage evacuation 60 of the same length as the molding bench 40 and placed in parallel, between this molding bench 40 and the preparation mat 28 (cf. fig. 2 and 3).
- This cart discharge 60 is movable longitudinally for example on rails 61. It moves in front of a cutting station 62, where the prestressing cables 3 are cut between the successive beams 1, to separate the beams 1 from one another by same together.
- the cutting station 62 may include a torch, a saw circular, a chainsaw or any other suitable means.
- beams 1 can be routed transversely to a post evacuation 63 or longitudinally towards the outside of the building for example, where the beams 1 are stored on a storage area (not shown), either in bundles on pallet, or individually depending on their length.
