Definitions

  • the invention relates to the manufacture of wall and ceiling elements which are provided with longitudinal and transverse reinforcement and with lattice girders or the like.
  • the lattice girders protrude above the finished plate, they extend in the case of a double wall element between the two finished plates forming this, which can be any type of iron reinforcement which runs transversely to the plate surface.
  • the lattice girders are anchored with in-situ concrete to be filled in later.
  • transverse racks can also be installed, which are racks that divide the individual panels on a pallet in the longitudinal direction.
  • a further subdivision in the longitudinal direction, ie parallel to the longitudinal direction of the pallet, can be carried out in a further station, in which recesses and the like are also provided with appropriate formwork or free blocks;
  • built-in parts such as sockets and other installation devices can be used.
  • reinforcing bars extending transversely to the longitudinal direction of the pallet are used, which are provided with spacers, so that these bars do not appear on the lower surface, but are encompassed by the concrete on all sides.
  • transverse reinforcing bars are used here, but gaps are left, for example three bars are successively used and one space is left free, this missing bar will be used later, as will be explained later.
  • These cross bars can be inserted by means of automatic machines, which is known per se. Such an automatic insertion of the crossbars takes place with the aid of a machine or an automatic machine, which inserts the bars one after the other, which is why the pallet must be advanced accordingly. Of course, you can also move the inserting machine along the pallet.
  • the longitudinal reinforcement bars are then introduced, possibly after the pallet has been moved transversely into the parallel row, which is now returned to the drying station.
  • the arrangement is different, the width may be determined by the drying station, which does not have to be a paternoster.
  • the existing local conditions must be taken into account.
  • the lattice girders are inserted in another station.
  • the missing transverse reinforcements are inserted in such a way that they reach through the bars between the lower and upper chord or above the lower chord, so that they are also within the concrete mass after concreting.
  • the mounting of the bars within the concrete slab is to be improved.
  • the reinforcement is finished, so that the final check of the correct position of the reinforcement can also be carried out here. Concreting is carried out in a subsequent station, specifically by means of a concrete distributor, ie by means of a device which moves over the slab and applies the required amount of concrete in accordance with the plotted pattern. After that, the concrete is shaken in the usual way Way to condense. The plate thus finished is transferred to the drying station so that the cycle closes.
  • transverse reinforcements initially applied are introduced in the prior art by means of automatic machines.
  • a first source of error can be present here, although this insertion work is still relatively simple.
  • the reinforcement bars are removed from the coil, first aligned and then cut to length. This is not a very big problem with the cross reinforcement bars since they are relatively weak and short.
  • longitudinal reinforcement bars there are already sources of interference during alignment and cutting, which in turn lead to corresponding interruptions in an automatic production process. It can be assumed that, according to the prior art, the cut longitudinal reinforcement bars are gripped and put down by the inserting machine without any intermediate storage.
  • Such a manufacturing system for double wall panels is known for example from DE-C-3838711.
  • the invention has for its object to be able to operate an automatic production system of the type in question more continuously and thus more economically even when errors occur.
  • This object is achieved in that between the straightening and cutting machine and the second reinforcement station, in which the longitudinal reinforcing bars are applied, in principle also possible between the delivery of the first part of the transverse reinforcing bars and the first reinforcing station for the application of the majority of the transverse reinforcing bars.
  • a storage device is arranged between the lattice girder machine and the station for applying the lattice girders, in which a number of longitudinal reinforcing bars or lattice girders in a dimensioning and spatial distribution for several adapted to one or more plates - if appropriate to that of the entire range -Plates or pallets can be accommodated in advance and fed to the respectively associated pallet in a centrally controlled manner, so that the correspondence between the longitudinal reinforcement or the lattice girder assembly and the pallets or plates to be equipped therewith is ensured.
  • the storage device can have a number of consecutive storage locations for accommodating the longitudinal reinforcing bars or lattice girders, and associated ones to be delivered Have pallets, the design of the storage spaces and their loading and unloading and possibly movement path includes a variety of constructive options.
  • templates are provided in the context of such a storage device, which are guided in a type of circulation which, depending on the degree of filling of the memory serving as a buffer, can be of different lengths or comprises the passage of a different number of template receiving locations.
  • the mode of operation of the system equipped according to the invention is explained in more detail below for the longitudinal reinforcement step:
  • a number of templates are made available on which the respective reinforcements or lattice girders are placed, in the pattern that ultimately corresponds to the inserted reinforcement. This can be done in particular by driving the template to be filled under the straightening and cutting machine and by inserting the required number of longitudinal reinforcing bars into certain grooves or other recesses in the template. For example, if only one longitudinal rod is to be inserted, then after this one rod is thrown off, the template is advanced by one division; then, under certain circumstances, two bars are inserted, etc.
  • the template can also be designed to be movable in the longitudinal direction of the rod, so that a rod section is first inserted in this direction of displacement before the interruption - recess - and then the rod section adjoining the recess is added by a corresponding method, so that the rod sections in the after Cutting the resulting longitudinal position in the exit area of the straightening and cutting machine in Can remain unmoved in the longitudinal direction.
  • the overall distribution of the reinforcing bars over the template can be made by such a movability, if necessary without the aid of a gripping tool.
  • the alignment and cutting machine is included in the overall control, the separation takes place according to the plotter instructions.
  • the pallets run in a forced circulation, so that their sequence is unchangeable. This gives the requirement which template with the associated equipment on longitudinal reinforcing bars must be fed to the pallet that has arrived in the reinforcement station for the purpose of the longitudinal reinforcing bars.
  • the longitudinal reinforcement can be provided for one or possibly two floor slabs on a single template.
  • Both the plotter and the reinforcement pattern of the template are controlled by a central control unit, which specifies the sequence and the respective type of ceiling slab to be manufactured. If the pallets are short, the entire longitudinal reinforcement pattern for a pallet can be handled with one template, for long pallets this problem is solved by using two templates for one slab assignment.
  • the individual templates are completed in advance; That is, before the associated pallet enters the longitudinal reinforcement station, the template or the associated templates are prepared in the appropriate order.
  • the storage device is provided, which contains the templates prepared with the longitudinal reinforcing bars of different types.
  • a particularly preferred embodiment of the storage device works in this connection as follows: Below a straightening and cutting machine, a template is passed in an approximately horizontal direction and equipped with pre-cut longitudinal reinforcement bars such that the longitudinal reinforcement bars stored in grooves or the like of the template match the reinforcement pattern of one or more corresponds to the plates to be manufactured on a pallet.
  • the template thus completed is placed in a first hoist, which moves the templates in height relative to a lowering frame until the next free space above the already occupied template positions is reached. Then the template is pushed into this free space by whatever means.
  • the lowering frame is also a kind of hoist that moves down one pallet space step by step, in the rhythm in which the templates for loading the respective pallet are removed.
  • the template and the pallet space to be loaded match, then the template is moved out of the lowering frame and arranged over the pallet space to be loaded.
  • the longitudinal reinforcement bars are then placed in their entirety and maintaining their distribution pattern on the associated pallet space as follows: After moving the loaded template over the pallet space to be equipped, the longitudinal reinforcing bars are retained by the lifting device while maintaining the arrangement on the template lifted.
  • the lifting device can be designed as a magnetic gripper, which can be designed as a permanent magnet or electromagnet. Training as a mechanical gripper in the manner of pliers or the like can also be used. After you have lifted off the longitudinal reinforcement bars, the template that has thus been emptied is moved back into the lowering frame and the lifting device is moved towards the pallet, whereupon the longitudinal reinforcement bars are placed thereon.
  • the lifting device as a permanent magnet
  • this is done with the help of a stripping tool, otherwise by switching off the current when training as an electromagnet or opening the pincer-shaped gripping tools with mechanical training, so that the individual or parallel bundles of rods arranged in the pallet the specified pattern on the associated pallet space.
  • the lowering frame has a corresponding row of template spaces above and below the transfer location, so that a prefabricated or pre-equipped number of templates is kept in readiness in the manner of a buffer, whereby interruptions in the process or disturbances that affect the circulation of the pallets are appropriately intercepted can be. However, a malfunction can also occur in the area of the straightening and cutting machine, so that a number of receiving locations for empty templates is also provided below the transfer location.
  • a second lifting mechanism which is preferably arranged below the first lifting mechanism, the empty stencils are again moved into a standby position, from which they are fed to the straightening and cutting machine for a new assembly.
  • the empty templates must be able to be picked up. This is done in the form of a number of corresponding template locations below the transfer point in the lowering frame and in a corresponding feed stack below the straightening and deflecting machine, so that the overall height in the transfer area can be kept correspondingly low. This means that the memory for the blank templates is divided into two.
  • Figure 1 shows a top view in block diagram form of the circulation of pallets through different stations.
  • the correspondingly cleaned and prepared pallet - 39 in FIG. 2 - on which the ceiling panels (not shown) are to be produced are recorded in the plotter station 21 with regard to the outline shape of the ceiling panels to be produced on them - usually several on a correspondingly long pallet.
  • the ceiling panels can already be separated or limited here by transverse racks and possibly also longitudinal racks.
  • the pallet is longitudinally moved from the plotter station 21 into the lay-up station 22, in which recesses and the like are delimited by applying formwork bodies etc. Lateral and / or longitudinal racks can also only be installed in this station; this is based on the aim of designing the various work steps in the individual stations at the same time as possible in order to achieve fast and thus economical production.
  • the pallet then arrives in the second reinforcement station 24 for the application of the longitudinal reinforcement, which happens automatically after the reinforcement bars have been aligned and cut to length, as will be explained later.
  • the pallet arrives in the station 25 for the application of the lattice girders, which also happens automatically after the lattice elements have been produced automatically.
  • the pallet is then transferred to a station 26, in which transverse reinforcing bars are also inserted once.
  • the pallet is then transferred to a control station 27, in which the correct position of the individual parts, in particular the reinforcing bars and the lattice girder, is checked, whereupon the pallet is transferred to the concreting station 28 and compacted there by targeted concrete application in a uniform thickness of the concrete layer and by shaking is completed that it can be transferred to a drying chamber 30.
  • the design of the drying chamber can be made differently, so you can ensure a uniform dwell time at a constant temperature averaged over the period with the help of a paternoster rack, in which the fresh plate is guided up and down through the chamber, if necessary depending on the height in several up - and movements.
  • the pallets with the freshly concreted ceiling panels are lifted from the concreting station 23 with the aid of a crane (not shown) and placed on stacks arranged one behind the other in the crane conveying direction, for example ten pallets per stack on top of each other.
  • the dwell time of the lower pallets in each case will be longer than that of the pallets lying at the top in the stack, the latter, however, being exposed to a higher temperature, so that curing takes place more quickly.
  • the bottom pallet is removed from the stack 31, which is assigned to the exit of the drying chamber 30, as the best hardened one, for which purpose the pallets lying above this stack are lifted with the aid of a separate tool. With the help of the crane, the stack 31 is always supplied with the already largely pre-tied pallets of the other stacks.
  • the bottom pallet of the stack 31 is transferred to a lifting station 32, in which the now sufficiently hardened individual ceiling tiles are lifted off the pallet and fed to a storage location. After cleaning and, if necessary, further processing of the pallet thus freed up, it is transferred to the plotter station for the production of further ceiling panels, so that the pallet circulation is closed.

These storage devices form buffers which hold a series of prefabricated longitudinal reinforcements or lattice girder arrangements ready. If the associated straightening and cutting or lattice girder machine 33 or 35 fails because of a fault, i.e.
  • the pallet circulation can still continue while removing the already adapted longitudinal reinforcements and lattice girder arrangements held in the memory. During this time the fault in the area of the machines etc. can be remedied. If, on the other hand, an error arises in the area of the pallets which affects the pallet circulation, the machines 33 and 35 can continue to carry out the preprogrammed manufacture of the longitudinal reinforcements and lattice girder arrangement for upcoming pallets and store them in memory.
