Definitions

  • the invention relates to a method for reinforcing concrete slabs and a device for performing the method.
  • Concrete slabs or other prefabricated concrete parts of this type are generally provided with reinforcements. These reinforcements are first calculated and manufactured according to structural requirements and are then introduced in the direction in which liquid concrete is then poured and compacted.
  • the reinforcement is made from a stock of wire rods on site and by hand according to the static requirements of a concrete slab to be manufactured, connections being made mechanically at the intersection points by brackets or in some other way by welding, so that a mat-like reinforcement is produced.
  • a disadvantage of this procedure is that due to the manual production, the production speed is extremely low in comparison to the cycle speed in the production of the concrete slabs themselves. The production speed depends on it also very much depends on whether the reinforcement has a comparatively uniform structure or not. If, for example, numerous cutouts or breakthroughs have to be carried out in the concrete slab to be produced, the reinforcement has a relatively complicated structure. So that you can keep up with the cycle speed of the production of the concrete slabs themselves, several workplaces are required, which must be worked on simultaneously. Nevertheless, there can be considerable dead times, especially when the reinforcements to be manufactured differ greatly from one another.
  • factory-made reinforcement mats are used, which are adapted to the respective requirements before Crt.
  • sections are cut out of the mats that correspond to openings and recesses.
  • additional reinforcement bars may be necessary to install additional reinforcement bars at individual locations of such mats.
  • the device for performing the method is characterized by the features of claims 14 to 20.
  • the invention is based on the knowledge that the problem can be achieved by automated manufacture of reinforcements on site.
  • the cycle speed during the manufacture of the reinforcement can be brought into a range that corresponds to the (fastest) production speed of concrete slabs for the most favorable case for this.
  • the wire rods are withdrawn from a wire coil bearing, they can be made extremely low.
  • wire diameters are also very simple, space-saving and therefore inexpensive.
  • Automation in the manufacture of the reinforcement also makes it possible to use workers who do not require high qualifications. In particular, it can be automatically displayed at which locations a wire of which diameter and in what length must be arranged in the reinforcement. Everything else can be fully automated, in particular the connection of the wire rods to one another. Since the necessary connection of the wire rods to each other is only required to a certain extent until the concrete has been introduced and hardened, it may be sufficient to design the immovable arrangement of wire rods with one another only for a time.
  • an electromagnetic lifting device can be provided with which the laid out mat-like in an electromagnetic manner Can be removed and taken to the reinforcement Ferti g un g multiplexing frame generating apparatus and held in position until the cast concrete a certain cure has reached.
  • the reinforcement can be placed on a pallet or can be manufactured on this pallet and can be placed in an intermediate storage with this.
  • This intermediate storage means that the manufacture of the reinforcements is comparatively independent of the currently required cycle time of the manufacturing device.
  • such a memory can serve as a buffer between several devices for manufacturing reinforcements and several devices for manufacturing the concrete slabs.
  • Wires of different diameters are stored in a wire store.
  • wire of a selected diameter is drawn from the wire store and straightened.
  • the aligned wire rod is cut to length.
  • the wire rod cut to length is arranged in position in the grid according to the stipulation of the calculating reinforcement and fixed in position.
  • the able fixed mattenarti g e and finished in so far as reinforcement is temporarily stored in a buffer, in which, as shown, manufactured reinforcements can be latched by other devices.
  • These temporarily stored mat-like reinforcements are called up as required by a manufacturing device for concrete slabs. As shown, several such manufacturing devices can be provided.
  • Such a manufacturing device can, for example, have the structure according to DE-PS 30 47 650.
  • the implementation of the various steps is controlled by a controller, whereby an essentially automated manufacturing operation can be achieved.
  • Theoretically it is possible to completely automate the production of such mat-like reinforcements.
  • a semi-automatic operation should be expedient, in which workers without highly qualified training are left to pulling, cutting and positioning, with appropriate help automatically being given will. For example, the specification of the diameter of the wire to be drawn, the length with which it is to be cut, and the position in which the wire rod that has just been cut has to be positioned.
  • the mat-like reinforcement which is almost ideally adapted to the respective structural requirements, must remain unchangeable in its arrangement at least until the concrete in the production device has reached a certain hardening state.
  • the positioned wire rods are firmly welded to one another at the crossing points, at least at selected crossing points, for example by means of spot welding. If the wire rods are arranged in a predetermined grid, spot welding devices can be arranged in the same grid, and can only be lowered and actuated for spot welding after the wire rods have been positioned.
  • spot welding devices can be arranged in the same grid, and can only be lowered and actuated for spot welding after the wire rods have been positioned.
  • this procedure is relatively complex and expensive in view of the fact that the fixed connection is only required between the positioning and the degree of hardening of the concrete mentioned.
  • Clamping or another mechanical connection which can be regarded as stable for a relatively short time, may already be sufficient.
  • a simple and safe solution is provided if the manufactured mat-like reinforcement is lifted by means of an electromagnetic lifting device without any other measures and lowered in the manufacturing device for the concrete slabs and this is held in an electromagnetic manner) until it is ensured in another way that that the wire rods can no longer shift against each other.
  • This can be achieved, for example, by clamping the wire ends on the edge by means of separate (lost) supports in the pallet for the production of the concrete slabs or in some other way.
  • the cycle speeds in the manufacture of the concrete slabs are different with regard to the size of the respective concrete slab and with regard to the complexity of the concrete slab, and because of this, the cycle time also applies to the semi-automatic or fully automatic production of the mat-like reinforcement speed can also differ with regard to the complexity of the reinforcement pattern, it is very expedient to provide a buffer store in which buffering is carried out. Mat-like reinforcements from different production lines for such reinforcements can also be temporarily stored in such a buffer and can also be distributed to different production devices.
  • Fig. 2 shows a conventional pallet 1, on the supports 2 are arranged in a grid dimension which corresponds to the grid dimension of the mat-like reinforcement to be manufactured. These supports are preferably designed to be interchangeable so that they can be removed at those points where they are not required.
  • the supports 2 have mutually perpendicular slots 3 and 4 in the top, which are wedge-shaped or V-shaped and into which the wire rods are inserted.
  • wire rods 5 of a first diameter and wire rods 6 of a second diameter can be used in the same reinforcement 15.
  • This reinforcement 15 has a recess 17, in whose area no wire rods are to be provided due to the static calculation and the other conditions of the concrete slab to be manufactured.
  • the wire rods 5, 6 are essentially recorded immovably against each other, which is why a simple temporary storage is possible. Welding is not necessary.
  • FIG. 2 shows a marking grid 7 which is height-adjustable in accordance with arrow 16.
  • cold light sources 8 are provided, by means of which a light beam 14 can be emitted on or into the area of one of the supports 2 of the pallet 1 when excited.
  • Such a cold light source 8 is formed by optical fibers 9 which can be "excited” by a light source 10 at the other end.
  • the excitation of the light source 10 takes place via a controller 11, which, based on the calculated reinforcement corresponding to the static requirements, excites the corresponding light source 10, in the area of which a wire 5, 6 must be arranged (or vice versa, may not be arranged).
  • the control can take place in such a way that in a first step wire rods 5 of a first diameter are processed in a second step wire rods 6 of a second diameter etc. Furthermore, the control can also be such that rows and columns are scanned. The control is designed so that it indicates to the worker where wire rods of which diameter are to be arranged.
  • the marking grid 7 according to FIG. 2 is also designed such that lifting magnets 12 are provided at the marking points corresponding to the crossing points and can be controlled by a lifting magnet control 13.
  • the marking grid 7 is lowered with the aid of the height adjustment 16, and the lifting magnets 12 are then excited with the aid of the control 13.
  • the mattenarti g e is reinforcement 15 is completely lifted and can be connected to any place, in particular by promoting the production apparatus.
  • marking grids can be provided for the optical markings and for the lifting device.
  • a marking grid for optical markings which does not have to be adjustable in height, is provided and the wire rods 5, 6 are arranged in the slots 3, 4 of the supports 2 of the pallet 1 fixed in their position.
  • the pallet 1 After completion of the mat-like reinforcement 15, the pallet 1 is placed in an intermediate storage.
  • a corresponding marking grid for the lifting device is actuated only on site for introduction into the manufacturing device of the concrete slabs, this marking grid having to be adjustable in height.
  • the pallet 1 can not only be used for the positioning of the wire rods 5, 6 to form the mat-like reinforcement 15, but can also be used for the production device with a suitable design. In such a case, it is advisable to make the supports 2 interchangeable, and furthermore as ver Form a permanent element, as it remains in the concrete slab once it has hardened.
  • control 11 of the optical marking it should also be mentioned that it can be controlled, for example, with the aid of a computer, and that it can also be controlled, for example, via partially transparent films (negative or positive).
  • control of the lifting device it should be noted that in individual cases not all lifting magnets 12 in the respective marking grid 7 need to be controlled, but only those that are sufficient on the basis of mathematical calculation to remove the mat-like reinforcement 15 such that the wire rods 5, 6 remain immovable.
  • the method according to the invention achieves a considerable rationalization effect in concrete plants. Substantial steel savings are also possible since waste can be avoided almost completely.
