Definitions

  • the invention relates to a manufacturing device for the production of relatively large, plate-shaped prefabricated concrete parts, in particular for prefabricated ceilings in the form of so-called hollow concrete planks, with the features of the preamble of claim 1.
  • Large plate-shaped prefabricated parts of the type in question are provided with columnar cavities running in the longitudinal direction in order to emulate the effect of a T-beam, i.e.
  • the finished parts are subjected to tension in the lower chord area and to pressure in the upper chord area, while the webs remaining between the cavities serve to connect these two belt zones.
  • the large-volume cavities are ensured during the molding process by inserting a corresponding number of parallel pipes into the mold space above the pallet forming the mold base, which engage in corresponding bores of transverse stops which are arranged transversely to the direction of displacement of these pipes and which limit or limit the mold space. subdivide if several finished parts corresponding to smaller and different sizes are to be produced in one operation on the same pallet.
  • these force-transmitting side connections are achieved in that the adjacent side walls of the finished parts are formed with undercuts, which then form a cavity which is open in the form of a gap at the top and which is delimited by the undercuts. This cavity is filled with in-situ concrete. Due to this design, adjacent prefabricated panels can be supported in such a way to one another that thrust forces versetzun g sok to the respective neighbor finished part can be transmitted. According to another known embodiment, the side walls in question are conically narrowing upwards, so that these side walls enclose a wedge-shaped cavity between two adjacent prefabricated parts. In order to be able to ensure the force-transmitting connection here by filling with in-situ concrete, end areas of reinforcing bars of the precast elements must be inserted into this wedge-shaped cavity.
  • the invention has for its object to improve the manufacture of the plate-shaped finished parts in question in such a way that the manufacturing outlay is reduced both in terms of the design of the overall devices involved in the manufacture and in terms of processing time, so that the finished parts can be produced more easily and more cheaply.
  • the wall bodies are designed as tubes and, furthermore, can preferably be actuated in synchronism by the same displacement mechanism.
  • the reinforcement for the finished part can be arranged on the pallet in a processing station upstream of the manufacturing device, as is also the case for crossbeams I and any longitudinal bobbins if there are several, correspondingly shorter ones on the same pallet and / or smaller finished parts are to be produced.
  • At least the cross racks also serve to align and hold the reinforcing bars, for which purpose the cross racks are in particular formed in two parts.
  • the lower lower parts of the cross racks are placed on the pallet surface or positioned there before the reinforcing bars are applied, they are designed in such a way that they simplify the insertion of the reinforcing bars in the longitudinal direction of the respective production part and make them particularly precise.
  • the upper parts of the cross racks are placed on the lower parts, which can happen before the pallet is inserted into the manufacturing device for concreting the finished part (s), but some or all of the upper parts of the transverse racks can only be placed within the manufacturer tion device are applied to the associated lower parts, at least in part also in a fixed arrangement on the form frame of the device.
  • the mold side parts and at least part of the racks remain within the mold frame of the device, the cured finished parts are removed from the mold.
  • Pelettes are particularly simple and time-saving, especially when you consider that after curing, the preparation of the pallet, namely cleaning and oiling, can be carried out much more quickly than is the case with the known pallets with hinged side walls.
  • two successive movement processes are required for the shaping of the freshly formed production part, namely the removal of the wall body and the subsequent lifting of the mold frame, but the first operation of pulling off the wall body is synchronous with the pulling out which is required anyway perform the shaped body, so that only the lifting of the mold frame is required as a working step over the required pull-out time of the shaped body.
  • the pallet is provided with slots in its edge areas in such a way that those extending transversely to the longitudinal direction Reinforcing bars can be inserted there.
  • the slots are dimensioned such that the space remaining after inserting a reinforcing iron into the slot base is closed by the guide rail of the wall body which retracts when the mold is closed.
  • a bushing is inserted into the correspondingly larger openings in the transverse racks for receiving the shaped bodies, and the sliding property can be adapted to the shaped bodies.
  • at least the bushings of at least one of the two transverse racks, which limit the shape in the longitudinal direction, are provided with lugs which are directed downwards towards the mold space floor and touch it as far as possible.
  • the lugs are embedded in corresponding channels in the lower parts of the cross racks. In this way, it is achieved that the hollow bodies formed by the shaped bodies 5 are ventilated in the finished part or that water collecting there can flow off via the channels formed by the lugs.
  • the top view according to FIG. 1 shows only a hint of the device frame 1, on the vertical guides 2 protruding into the plane of the picture, the side parts, which are not shown in detail, are guided to a frame 3 'which form the side walls 3 of the mold frame when they are on the holder 4 together with the tubular shaped bodies 5 held wall body 6 are retracted into the mold, as is shown by the displacement position of the holder 4 and thus the shaped body 5 and the wall body 6 shown with solid lines.
  • Transverse racks 7, of which several can be provided, run transversely to the direction of displacement of the holder 4 or the molded body 5 and the wall body 6, depending on how many longitudinal sections of prefabricated parts are to be produced in the mold space designated overall by 10.
  • the holder 4 with the shaped bodies 5 and the two lateral wall bodies 6 is shown in dashed lines - in the direction of the double arrow shown in FIG. 1 - in the position in which the tubular bodies 5 and 6 are pulled out of the molding space 10.
  • the bodies are in this position shown in dashed lines, for example, when a freshly formed molding is to be removed from the mold.
  • the solid position of the parts 4, 5 and 6 is therefore referred to with regard to the molded body 5 as the insertion position and with respect to the wall body 6 as the molded layer, while the position shown in broken lines for the molded body 5 as the extended layer 12 and with regard to the wall body 6 as the mold release layer 14 are.
  • the sliding guide for the holder 4, to which the shaped bodies 5 and the wall bodies 6 are fastened, is not shown any further. It is firmly connected to the device frame 1.
  • the enlarged partial cross section according to FIG. 2 shows only one side region of the molding space 10 with the side wall 3, which results from a plurality of partial surfaces when the wall body 6 is shifted into the molding position 13 (FIG. 1), which faces the mold interior 10 '.
  • the molding frame 3 ' has a wall section 15 which delimits the upper edge region 24 of the molding space 10 and is slightly inclined to expand the molding space 10 towards the bottom.
  • the wall section 15 runs out towards the bottom in an edge 16 which adjoins the outer surface of the wall body 6.
  • This lateral surface has a wall part 17 that bulges out toward the interior 10 'of the mold space, which extends from the edge 16 to a guide rail 18 to which the wall body 6, which is designed as a tube, is firmly connected.
  • This guide rail 18 comprises the freely projecting edge part of a side wall extension 19, which is formed on the pallet 8 or is fixedly arranged thereon. The same relationships are present in mirror image in the other side wall area, not shown.
  • Fig. 2 shows the situation with "closed" mold space 10, which means that a pallet 8 is inserted into the device supported by the device frame 1, whereupon the mold frame 3 'is lowered via the indicated vertical guide 2 until it reaches the position shown occupies. Then the wall body and the molded body 5 are inserted into the molding space, which is to be indicated by their cross hatching. So that the side wall 3 of the mold space 10 is closed, which b-indicates that between the outer surface of the wall body 6 and the edge 16 of the wall section 15 and between: he guide 18 and the side wall approach 19th such dense conditions prevail that the concrete now to be poured into the mold space 10 in the state shown cannot escape through these contact points.
  • supports 20 are provided which are held on the molding frame 3 '. These supports 20 are provided at regular intervals over the length of the tubular wall body 6 in its shaping position.
  • the wall body 6 together with the molding 5 are first pulled out of the molding space.
  • the forces exerted on the adjacent surfaces of the fresh prefabricated part are tangential in nature, so that no adhesive effects occur which could damage the surface of the corresponding concrete walls of the fresh prefabricated part.
  • the mold frame 3 ' is raised. All that is left to do is to loosen the narrow surface strip between the wall section 15 and the adjacent surface part of the fresh finished part.
  • the wall body 6 and the molded body 5 are pulled off with the fresh finished part supported by an end wall, in this case that of the last transverse stop in the pulling direction, this is not the case when the mold frame 3 'is lifted off with respect to the upper edge of the mold space 10. Therefore, the wall section 15 is slightly inclined and narrow, as seen in the vertical direction, so that the release process can be carried out without damage.
  • knobs 42 are provided in the area of the wall sections, which are used to hold Qterabstellern 7. For this purpose, these are provided with groove sections 43 at a corresponding point, as is shown in FIG. 3 is indicated.
  • the engagement between the knobs 42 and the groove sections 43 of the transverse racks 7 serves for their precise positioning in different positions in the molding space 10 depending on the length of the finished part to be manufactured.
  • Fig. 3 shows two pre-cast finished parts, which have the same shape as the cross racks 7 and have corresponding names. These parts are assigned to one another with their end faces. It can be seen that a cavity 25 is formed due to the wall parts 17, which is poured at the construction site with in-situ concrete.
  • FIG. 4 and 5 show a view into the molding space along the direction of displacement of the molded bodies 5 and the wall members 6 onto the corresponding broad side of a transverse switch 7.
