Definitions

  • the invention relates to a formwork for the production of concrete components according to the preamble of claim 1.
  • the object of the invention is to form a formwork of the type described in such a way that it has an improved rigidity with respect to the composite material used as formwork skin while maintaining the lowest possible weight and thus simple handling.
  • the stiffness of the at least one formwork element is substantially improved by the stiffening element designed like a space lattice, wherein in particular, the stiffening element can also be manufactured inexpensively and has only a low weight, so that the formwork as a whole can also be manufactured inexpensively and with a low weight that facilitates handling.
  • stiffening element it is also possible, particularly in the case of U-shaped formwork elements used for the manufacture of beams or foundations, to reduce the number of spacers or to increase the mutual spacing of such spacers, so that this considerably simplifies the formwork with the same rigidity Manufacturing and cost reduction result.
  • At least one stiffening element is fastened to at least one surface of the formwork formed by the formwork element in such a way that it extends adjacent to this surface in the longitudinal formwork direction.
  • At least one stiffening element is provided which, with its longitudinal extent, is arranged perpendicularly or transversely to these surfaces between the two formwork elements.
  • at least one further stiffening element is provided on each surface, which rests against this surface and extends in the longitudinal direction of the relevant formwork element.
  • the formwork element 1 which is used for example for the production of beams or foundations made of concrete, is from the Composite material bent so that it has a U-shaped cross-section, ie two vertical, spaced side surfaces 5 and 6 and a lower floor or yoke surface 7 connecting these side surfaces, the bending edge between the side surfaces 5 and 6 and the bottom surface 7 runs parallel to the structural steels 2 and perpendicular to the structural steels 3 angled at these bending edges.
  • a plurality of spacers 8 are provided which run perpendicular to the side surfaces and connect the latter to one another in a pressure-resistant and tensile manner also in the longitudinal direction of the formwork element 1, ie are arranged one behind the other perpendicular to the plane of the drawing in FIG. 1.
  • Each spacer consists of a rod-shaped element 9 made of iron or steel, which is formed at each end with a fork-shaped section 10 with two legs 11 each.
  • the legs 11 of each section 10 are arranged parallel and at a distance from one another and extend in the longitudinal direction of the element 9.
  • the length of each leg 11 is equal to a multiple of the diameter of the structural steels 2 and 3, that is to say in the illustrated embodiment, greater than three times the diameter thereof Structural steels.
  • the fork-shaped sections 10 are, for example, made of flat steel by bending and in the region of the yoke section 12 connecting the legs 11 with the each end of the element 9 connected or welded.
  • each leg 11 is formed by holes 13, 13 'and 13' and arranged in the longitudinal direction of the leg row of holes, each bore 13, 13 'and 13' on one leg 11 of a corresponding hole on the other leg 11 is congruent.
  • the sections 10 penetrate the two shrink films 4, so that the legs 11 each protrude beyond the outer surface of the formwork element 1.
  • the legs 11 of each section 19 each comprise a structural steel 2.
  • Each stiffening element 14 consists of three longitudinal rods or structural steels 15-17 extending in the longitudinal direction of the stiffening element 14, which in the illustrated embodiment have the same diameter as the structural steels 2 and 3 and are arranged parallel to one another and at a distance from one another such that they are in the Cross section of the stiffening element 14 form the corner points of an equilateral triangle, the shorter base between the structural steels 15 and 16 and the larger leg between the structural steels 15 and 17 or 16 and 17 are formed.
  • the structural steels 15-17 are connected to one another by a plurality of elements 18, each of which is bent in a V-shape and also made of structural steel, for the lattice girder-like stiffening element 14.
  • Each stiffening element 14 is arranged on the outer surface of the respective side surface 5 or 6 so that it rests with its structural steels 15 and 16 on the outer surface or is immediately adjacent, the structural steel 15 being above the structural steel 16 in the embodiment shown.
  • Each stiffening element 14 is held on the relevant side surface 5 or 6 in that the structural steel 15 is also received between the two legs 11 of the spacers 8.
  • a bolt or nail 19 for example, through the overlapping bores 13 'of the section 10 in question, the structural steel 15 and the stiffening element 14 are secured against slipping out or down on the sections 10 of the spacers 8.
  • stiffening elements 14 which have a particularly high moment of inertia in the loading direction (perpendicular to these side surfaces) due to their configuration and arrangement described above on the side surfaces 5 and 6, it is also possible to determine the distance that the spacers 8 have in the longitudinal direction of the Formwork element 1 (perpendicular to the drawing plane of FIG. 1) from each other to choose larger than would be possible without the use of the stiffening elements 14.
  • FIGS. 6 and 7. A further embodiment is shown in FIGS. 6 and 7.
  • the formwork consists of at least two at a greater distance Formwork elements 1 'arranged from each other, which in turn are made of the same composite material as the formwork element 1.
  • the formwork element 1 ' is part of a concrete formwork for producing a concrete foundation, and in the embodiment shown, the formwork element 1 'also has a U-shaped cross section, so that with two such formwork elements 1' two parallel and spaced-apart beam foundations or sections thereof can be produced.
  • the space between the two formwork elements 1 ' is bridged by a plurality of stiffening elements 14 arranged one behind the other in the longitudinal direction of these formwork elements, that is to say in the direction perpendicular to the plane of the drawing in FIG. 6, each with its longitudinal extension perpendicular to the mutually facing side surfaces 6 of the two formwork elements 1 'Lie and extend with their two ends in the mold cavity 24 for holding the concrete of the two formwork elements 1 through the side surface 6, in the embodiment shown directly in the region of the upper longitudinal edge of the formwork elements 1'.
  • the stiffening elements 14 are held in a suitable manner (for example by tying) to the structural steels 2 and / or 3 of the side surfaces 6 of the two formwork elements 1 '.
  • the stiffening elements 14 each penetrate the shrink films 4 'in the area of a lattice opening or in the area of an enlarged opening, which was created by cutting out a partial length of at least one of the structural steels 2 or 3 in the area of the passage point for the stiffening element 14.
  • the stiffening elements 14 mutual support of the two formwork elements 1 'arranged at a distance from one another, all stiffening elements 14 being embedded in this concrete after the introduction of the concrete into the mold spaces 24 of the formwork element 1', so that it is then after the two beam foundations or whose sections are possible to place a flat material 25, namely the already described composite material, on the stiffening elements 14, which then forms the lower, horizontal formwork wall or formwork skin for a concrete slab to be subsequently created.
  • the formwork according to FIGS. 6 and 7 can thus be used in particular as lost formwork for the production of concrete walls or foundations with a concrete ceiling above it.
  • the spacers 8 or their sections 10 can also be used to two in the longitudinal direction of the formwork, i.e. 1 adjacent to each other and in the connection area on the side surfaces 5 and 6 and on the yoke surface 7 on a partial length overlapping formwork elements 1 and 1 'to connect.
  • two adjacent structural steels 2 of the two formwork elements in the connection or in the overlap area and also the structural steel 15 of the stiffening element 14 are then received between the legs 11 of the corresponding spacers 8, the nail 19 serving to secure them through the bore 13 'of the two Leg 11 is inserted.
