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 IT-A-1 149 739 (& US-A-4 526 739).
  • This formwork uses built-in parts that are provided with an upper stop for the fastening screws, which is flush with the upper edge of the formwork.
  • the fastening screws used for the exact positioning of the built-in parts are inserted from above through recesses in a special base plate extending over the bottom of the formwork and screwed into nuts welded onto their underside. With their screw heads, they protrude beyond the upper edge of the formwork.
  • the sleepers are manufactured with the sole surface facing upwards. After lifting the finished part must be rotated for equipment and storage in the known formwork. For this, in the known formwork solution, in order to be able to finally store the finished part, a special operation is required in which the part is set down and the auxiliary devices protruding from the base surface have to be removed.
  • the base plate When lifting out - as a further disadvantage - the base plate must also be lifted because the eyelets for lifting the finished part are anchored in it. The base plate must therefore always be re-installed and aligned even with finished parts of the same type
  • the object of the invention is to develop a formwork, the auxiliary devices of which can be installed from above, in such a way that all auxiliary devices, including their fixing means, do not protrude beyond the upper edge of the formwork and can be anchored at any point in the ground.
  • 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.
  • construction elements - clamping claws and clamping devices - are arranged so that they can be moved longitudinally - as far as this is necessary for the built-in parts - with screw sleeves that can be moved so that the screw sleeves can be fixed in the clamping bed in any position required for the formwork of the various finished parts.
  • Retaining screws that are at least flush with the upper edge of the formwork can be screwed into the screw sleeves from above, which immovably hold the individually movable installation parts in the formwork. 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 key 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 the base plate from being 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 ge of built-in parts 8 of the finished parts 2 in the formwork can be geometrically defined in the form of templates.
  • tubular sleeves - serve screws 9, which are anchored in the floor in a rigid and tensile manner for exact fixing.
  • This rigid and tensile anchoring is achieved by screwing the fastening screw 9 from above to the stop 10 into a threaded sleeve 11 arranged under the fitted base plate 5.
  • the threaded sleeve 11 and 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 desired arrangement predetermined by the recesses 7 of the base plate 5, by designing the sleeves 11 like a hammer head and with this hammer head 13 in recesses 14 of the clamping claws 12 and displaceably the clamping claws 12 with lugs 15 in corresponding, longitudinal rails 16 arranged in the substructure of the formwork 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. With the top plates 17, the set-up element 6 comprises the head connection of two adjoining finished parts 2 / n, 2 / n + 1 in the fitted bed 1 Clamping device 27 can be screwed in. The ends of the clamping device 27 engage in the profiles of the longitudinal rails 16, are 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 thread outer diameter 47 of which is smaller than the outer 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 is 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 cover 50 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.
