Definitions

  • the invention relates to a formwork for prefabricated parts made of reinforced concrete, as generically described in the preamble of claim 1.
  • Such formwork is known from DE-OS 29 48 303 and a publication in the magazine “Dieschwbahn”, issue 9/1982.
  • the sleepers are concreted in one piece, one after the other, without stops between the individual sleepers. This means that all sleepers concreted in a fitted bed must be excavated in one piece and then turned and separated.
  • the built-in parts in the formwork and the devices for lifting the finished parts protrude from the surface at the top during production and thus above the upper edge of the side parts of the formwork. Since the top surface of the prefabricated part comes to lie down in sleepers in sleepers, sleepers must be turned for final storage. Parts protruding from the surface must be removed during intermediate storage. Interim storage requires additional work and thus additional costs. Pulling out the built-in parts over the edge of the side formwork also means pulling out the formwork over the edges of the side elements and the use of vibrating planks to compact the concrete is impossible.
  • the object of the invention was to eliminate the above-mentioned shortcomings and to develop a formwork in which each finished part can be individually lifted, rotated and disposed of without intermediate repositioning.
  • the finished parts Due to the construction of the parking device, which is recessed between the side elements of the formwork, the finished parts can be pulled off and shaken over the edges of the side formwork.
  • the finished parts By arranging two oppositely arranged head plates to be placed between successive prefabricated parts and by arranging pegs on the head plates, for example in the axis of gravity of the finished parts, for lifting out, the finished parts can be separately lifted from the formwork after rotation, rotated and finally stored without intermediate storage being necessary becomes.
  • a variant of the storage element according to claim 1 is described in claim 2, in which the distance between the head plates can be fixed independently of the base plate. This ensures that the finished parts can slide on the base plate when relaxing. Taking the floor panels with you the finished part due to the shortening of the exposed lengths of the tension wires in the area of the storage elements when relaxing and a new alignment of the base plates for a new concrete process is avoided.
  • a clamping bed 1 in which the tie rods 3 are clamped from abutment to abutment, finished parts 2/1, 2, ... n are produced one behind the other in a formwork which extends essentially in the longitudinal direction.
  • the formwork is built up from the side elements 4 of the prestressed bed, the base plates 5/1, 2, ... n fitted between them and storage elements 6.
  • the storage element 6 includes with the head plates 17 the head formwork of two adjacent prefabricated parts 2 / n, 2 / n + 1 in the fitted bed 1.
  • the head plates 17 sit on their lower edge 18 on the base plates 5 / n, 5 / n + 1. At their upper edge 19 they are supported by the clamping plate 21 resting on brackets 20 with the help of the clamping screw 30 guided in the hold-down device 26 and the clamping device 27 pressed against the base plates 5.
  • the clamping plate 21 keeps the top plates 17 at a distance above.
  • the wedge-like stops 23 attached to the hold-down device 26 press against counter-stops 22 of the head plates 17 and hold them by means of the lugs 31 arranged on the lower edge 18 of the head plates 17, the base plates 5 / n, 5 / n + 1 at a distance.
  • Pins 25 are arranged approximately in the middle on the head plates 17, on which the finished parts 2 can be lifted and rotated from the clamping bed 1 with the aid of suitable pre-example caps 332 directions of a lifting device 32.
  • All of the built-in parts 9, 17, 21, 30 which can be inserted into the fitted bed 1 are dimensioned in such a way that they do not protrude beyond the edge of the side elements 4.
  • the head plates 17 are held in their lower region by means of claw-like claws 35 fastened to the hold-down device 26, into which correspondingly shaped stops 36 of the head plate 17 engage.
