Definitions

  • the invention relates to a formwork for prefabricated parts made of reinforced concrete, as generically described in the preamble of claim 1.
  • the fixing means for the built-in parts are inserted from above into recesses in the base plate, so as to fix them in terms of their geometrical position, while holding them from above by tensioning devices arranged on the side elements of the formwork be pressed firmly against the floor slab.
  • the disadvantage of such fixation of the built-in parts is that the device parts projecting beyond the upper formwork edge make it impossible to pull off the formwork over the edges of the side elements and the use of vibrating planks to compact the concrete.
  • the fixing means are inserted in front of the displacement of the bottom plate (die) and combined with the base plate or must be installed from the difficult-to ga n equalized bottom of the formwork forth.
  • the arrangement of the suspension devices for lifting the sleepers and the conical ends of the fastening bolts show that even with this formwork solution there is no free top of the formwork for pulling off and compacting with a vibrating screed.
  • the sleepers are manufactured with the sole surface upwards. After excavation, the finished part must be turned for equipment and storage. In order to be able to finally store them, both formwork solutions require a special setting, in which auxiliary devices protruding from the base surface must be removed.
  • the object of the invention is to develop a formwork in which all auxiliary devices including the fixing means can be installed from above and also do not protrude beyond the upper formwork edge.
  • Embodiments of the invention contain claims 2 to 4.
  • the invention solves the problem by a system of rail-like profiles in the substructure of the fitted bed.
  • each position required for formwork of the different precast elements can be fixed in the fitted bed.
  • Retaining screws which are at least flush with the upper formwork edge and which hold the individually movable built-in components in the formwork immovably can be screwed into the screw sleeves from above. When concreting, it can be pulled off over the formwork edge and compacted with a vibrating screed.
  • Claim 2 describes an expedient embodiment of a clamping screw 9 and additional elements, with the aid of which the built-in part 8 is protected against bending and cement against the penetration of cement paste into the interior of the built-in part 8.
  • the clamping screw 9 has an Allen head so that it can be released without protruding from the concrete surface.
  • a shoulder 48 is formed between the Allen head and the shaft, with which it presses an elastic ring 49 against a nut 40.
  • the nut passes on the pressure via a washer 51 to the mounting part 8, the lower edge of which is pressed tightly against the base plate, thereby preventing cement paste from penetrating into the interior of the mounting part 8.
  • the shaft of the tensioning screw 9 tapers in the central area and thereby creates space for a mounting sleeve 44 for centering the built-in part 8.
  • the cover 50 according to claim 3 protects the Allen key as well as the interior of the built-in part 8 against the penetration of concrete during concreting.
  • the measure according to claim 4 prevents that the bottom plate is distorted by tightening the clamping screws.
  • 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 instep bed, the base plates 5/1, 2, ... n fitted between them and storage elements 6.
  • the base plates 5 have recesses 7 - in the example shown simple bores - through which the position of built-in parts 8 of the prefabricated parts 2 in the formwork can be geometrically defined in the form of templates.
  • the fastening of the built-in parts 8 - in the example shown tube sleeves - serve screws 9, which are anchored in the floor to be rigid and tensile for exact fixing.
  • This rigid and tensile anchoring is achieved by the fastening screw 9 from above to for stop 10 is screwed into a threaded sleeve 11 arranged under the fitted base plate 5.
  • the threaded sleeve 11 as well as the tubular sleeve 8 are pressed firmly and rigidly against the base plate 5 and the clamping claw 12 stiffening them by tightening the screw 9.
  • the position of the threaded sleeves 11 can be adapted to any possible desired arrangement, which is predetermined by the recesses 7 of the base plate 5, in that the sleeves 11 are designed like hammer heads and can be displaced transversely in recesses 14 of the clamping claws 12 with this hammer head 13 and the clamping claws 12 with lugs 15 in corresponding, arranged in the formwork of the longitudinal rails 16 are longitudinally displaceable.
  • the sleeves 12 can thus assume any position under the base plate 5.
  • the upper edges of the threaded sleeves 11 of the clamping claws 12 and the longitudinal rail 16 are arranged exactly in one plane, so that the base plate 5 is not distorted when the clamping screw 9 is tightened.
  • the built-in elements 6 are special built-in parts in the fitted bed.
  • the set-off element 6 comprises the top formwork of two adjoining prefabricated parts 2 / n, 2 / n + 1 in the fitted bed 1. It is fastened with the aid of a clamping screw 30 which is inserted into a screw sleeve 34 Clamping device 27 can be screwed in.
  • the clamping device 27 engages with its ends into the profiles of the longitudinal rails 16, is longitudinally displaceable in them and can be firmly clamped with the aid of the clamping block 29.
  • the clamping screw 9 has a screw head 36 with an Allen key. Its shaft is divided into an upper shaft part 37 with the shaft diameter 38 and a lower shaft part 42 with a shaft diameter 43 that is smaller than the upper shaft part 37.
  • the shaft diameter 38 is slightly smaller than the diameter of the screw head 36.
  • the shoulder 48 is created by the jump in diameter.
  • the clamping screw 9 ends in the threaded part 46, the external thread diameter 47 of which is smaller than the external diameter 43 of the lower shaft part 42. This creates the stop 10 between the shaft part 42 and the threaded part 46, against which the base plate 5 by screwing the clamping screw 9 against the threaded sleeve 11 is pressed firmly.
  • the clamping screw 9 can be pushed through the nut 40 of the rail fastening which is permanently installed in the head part of the installation part 8.
  • the upper shaft diameter 38 is therefore slightly smaller than the inner thread diameter 41 of the nut 40.
  • the lower shaft part 42 of the clamping screw 9 stands in a mounting sleeve 44 for guiding the installation part 8.
  • the shoulder 48 of the screw head 36 presses on an elastic ring 49 which The mounting part 8 presses firmly onto the base plate 5 via the nut 40 and the washer 51.
  • a lid 50 ver closes the opening for inserting the clamping screw 9 in the head part 39 of the installation part 8 flush with the upper edge of the side elements 4 of the formwork and thus protects the installation part 8 against the penetration of concrete.
  • 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.
