Definitions

  • the invention relates to a device for producing concrete slabs with a stationary concreting station, with pallets that can be moved through the concreting station, with end and side supports provided at the concreting station, which can be placed on or from the pallet inserted into the concreting station to form a composite formwork are removable, and with pushers to which the side shelves are attached.
  • front and side shelves can be pivoted as a whole frame around a horizontal shaft in order to remove the precast concrete element from a fixed base and place it on another base or pallet.
  • Front and side supports are adjustable for inclined side edges, so that silo construction or the like of different diameters can be built from the precast concrete parts (US-A-14 84 855).
  • the invention has for its object to design a device of the type described so that with it without assembly work and without the need to replace parts, an immediate change in the assembly line production of concrete slabs of one size on concrete slabs of another size is possible.
  • concrete slabs must be provided with reinforcements that protrude beyond the actual concrete slab. If these reinforcements are not to protrude from the top of such a concrete slab, but rather, for example, from the middle of a narrow side, then supports are used that are in two or more parts. In this case, the shutdowns consist of individual bars that are arranged one above the other. The bottom beam is first moved onto the pallet, then the reinforcement is inserted so that the protruding ends of the reinforcement rest on the bottom beam. Then an upper bar is placed on the protruding ends of the reinforcements.
  • the beams of such a multi-part storage on the surfaces where these beams come into contact with the protruding ends of the reinforcement with an elastically deformable layer to provide.
  • the beams of such a reinforcement are compressed after the reinforcement has been inserted, so that the layers on the beams deform and close tightly around the ends of the reinforcement.
  • the bars themselves consist of elastic material.
  • the stops have a knife-like approach, which is directed at an obtuse angle against the top of the pallet and rests on it.
  • This knife-like approach has resilient properties, so that when the pallet swings vertically, the end of this approach is always on the top of the pallet and closes there in a sealing manner. Since this knife-like approach is subject to wear over time, it is provided that a correspondingly shaped bar is removably attached to the parking space.
  • the bottom bar has a corresponding prismatic cross-section, so that the roof edge of the prism rests on the top of the pallet.
  • a vibration-damping connecting element is fitted between each rack and the associated pushing device.
  • the pallet is not to be moved into its loading position from below, but only moved in one plane, it is provided to raise or lower one of the shelves so that the pallet provided with the concrete slab is moved over or below this shelf can.
  • Figure 1 shows a plan view of an arrangement with which the inventive method can be carried out.
  • Two roller conveyors 71, 72 can be seen, on which a pallet 2 can be moved under rails 55 into a position which is below the loading position.
  • On the rails 55 there are carriages or sleds which carry pushers 6.
  • the stops 3 are located on these pushers 6.
  • four pairs of rails 55 and corresponding carriages or slides 5 are arranged around the loading position, the direction of movement of which runs parallel to the side surfaces of the concrete slab to be produced.
  • the shelves 3 are moved onto the pallet 2 in such a way that a long side 31 of such a shelf abuts an end face 32 of another shelf.
  • any size of concrete slab can be produced with this means by appropriately advancing the stands 3 by means of the feed device 6.
  • FIG. 2 shows a longitudinal section through a device according to the invention.
  • One carriage 51, 52 each run on rail pairs 55.
  • a feed device which is shown in FIG. 2 as a rod, is located on each carriage 51, 52.
  • a rack 3 is attached to them. Between them is the not yet hardened concrete slab 1.
  • the pallet 2 is seated on vibrating jacks 8. With the aid of a lifting device 9, which is in particular a piston-cylinder arrangement, the pallet together with the vibrating jacks 8 can be lowered from the loading position and lowered onto the roller conveyors 71, 72 will. It can be moved from this position under the carriage or carriage 53, 54, not shown in FIG. 2.
  • FIG. 3 shows a cross section through a device with which the method according to the invention can be carried out.
  • the pallet 2 is moved from the left onto the roller conveyors 71, 72 onto a vibrating block 8 which is in the lowered state.
  • the vibrating block 8 is then raised with a hydraulic device 9, so that the upper side of the pallet 2 touches the lower edges of the positions 3. This state is shown in Figure 3.
  • FIG. 4 shows a cross section through a single rack that is attached to a feed device.
  • the feed device is a piston-cylinder device 64, a vibration-damping connecting element 61 being fastened to the piston.
  • the parking space 3 is attached. It has a bar 62 on its underside, which is provided with a knife-like extension 63.
  • the cutting edge 65 of this extension 63 lies on the top 21 of the pallet 2.
  • the front surface 38 of the rack 3 is inclined at a small angle, approximately 2 °, from the vertical.
  • the strip 62 is fastened to the parking space with screws 66, so that. it can be easily replaced. This is necessary because when the concrete is shaken, the knife-like attachment 63 grinds on the surface of the pallet 2.
  • FIG. 5 shows a further embodiment for a parking device used in the device according to the invention.
  • This embodiment is used in particular in cases where the concrete slab is provided with reinforcements 4 which protrude from the side surfaces of the concrete slab.
  • the shutdown is formed in two parts in the case shown. It consists of a lower bar 33, which has a prismatic shape in its underside, the “roof edge” 69 resting on the top 21 of the pallet 2.
  • This "roof edge” 69 fulfills the same task as the knife-like extension 63 in FIG. 4.
  • On the lower bar 33 there is a layer 37 made of elastically deformable material. This layer can be made of rubber, but it can also be made of another deformable material, such as foam rubber.
  • the ends 41 of the reinforcement 4, which should protrude beyond the side surfaces of the concrete slab, are located between the beams 33 and 34 of the rack.
  • the beam 34 is also provided with an elastic layer 37.
  • the beams 33 and 34 sealingly enclose the end 41 of the reinforcement 4, so that no concrete can flow out. If the weight of the upper bar 34 is not sufficient for sealing closure, a spring 39 shown in dashed lines in FIG. 5 can be used be provided. This spring 39 can also be suitable for preventing the two beams 33 and 34 from opening or divergence when the concrete is shaken.
  • the arm 34 is pivotable about a joint 35. This makes it possible to place the reinforcement 4 unhindered vertically on the pallet from above.
  • the joint 35 is located on a plate 36, which is connected via a vibration-damping connecting element 61 to the piston rod 64 of a piston-cylinder device, which is the feed device in the sense of the invention.
  • the front surface 38 of the shelf 3 is inclined to the vertical, the angle of inclination in the example shown is approximately 4 °.
  • the beams 33, 34 can consist entirely of elastic material.
  • the elastic material can have sufficient damping properties, the oscillating metal 61, which is attached between the stop 3 and the piston cylinder device 64, can be dispensed with in such a configuration.
