Definitions

  • the invention relates to a formwork of the type explained in the preamble of claim 1.
  • Such formwork is known from US-A-3 547 397.
  • the known formwork uses formwork walls made of relatively thick wooden formwork boards, which are held in a position by separately manufactured, U-shaped wire brackets in which they are directed with one of their edges against the surface of a concrete base.
  • a holding element is further arranged by welding or by angling the wire of the bracket, which bears against the inwardly facing surface of each circuit board, so that the U-shaped bracket acts as a clamp.
  • the U-shaped bracket is relatively complex to manufacture and is also unsuitable for erecting formwork walls made of a latticework covered with a plastic film.
  • US-A-4 630 797 describes a formwork which also consists of a relatively stable formwork wall made of a slat-and-slat construction widened with a frame. It is a U-shaped component can be seen, which is able to exert pressure on opposite formwork walls, so that, for example, a wall can be manufactured step by step without a shoulder Marked transition between two wall parts cast at different times. This U-shaped part is also unsuitable for use with a formwork material made from a latticework covered with plastic film.
  • Another formwork is known from DE-OS 36 01 882.
  • a material known from DE-OS 31 42 148 is used, which consists of a latticework and a plastic film shrunk onto the latticework.
  • slab-shaped pieces of the material are cut to size and put together to form a mold cavity for molding the concrete parts, held at a pre-selected distance by spacers and with a supporting structure, e.g. the lattice girder known from DE-GM 87 09 851, for receiving the concrete pressure.
  • one edge of the formwork wall is angled in an L-shape and placed on the concreting base with this angle.
  • the leg can either point into the interior of the mold cavity or outwards.
  • bending the formwork walls has certain disadvantages. Angling inward interferes with the contact of the concrete with the concrete base, which is particularly noticeable when the concrete part is to be connected to the concrete base, for example a previously poured concrete part.
  • Formwork walls angled outwards lie exactly in the area in which the person must work, the support structure and the spacers attaches.
  • the angling requires a relatively complex, additional operation.
  • the panel used for the formwork wall must also be larger than actually required, which is noticeably more expensive given the relatively high price of the composite material.
  • the invention is therefore based on the object of creating a formwork which is easier and less expensive to manufacture and set up.
  • the inventive configuration of the assembly support part as a strip of a structural steel mat, the described arrangement of spacers or a support structure and the attachment of the assembly support part to the spacers and / or the support structure leads to an extremely stable formwork, which may also be provided by a single Worker can be set up.
  • the parts are simple and easy to use and quick to assemble.
  • the manufacturing costs of the individual circuit components are also kept within narrow limits. Nevertheless, the formwork according to the invention is extremely stable for the intended use.
  • the assembly support part according to the alternatives specified in claims 2 and 3 can either rest with a web on the concrete base or overlap the formwork wall from above.
  • the components of a formwork 1 according to the invention can be seen from FIG.
  • the formwork 1 contains one Formwork wall 2, which is able to enclose a mold cavity 3 for the production of a concrete part, in particular for a foundation, on two opposite longitudinal sides and two opposite end faces.
  • the formwork wall 2 consists of four individual parts 4, 5, 6 and 7.
  • Each of the individual parts is made of a composite material made of lattice work shrunk with plastic film.
  • the usual, bendable structural steel mat is used as the lattice work, which is preferably covered on both sides with the shrinkable plastic film.
  • the two side wall parts 4 and 5 forming the long sides of the mold cavity 3 are designed as flat, flat plates.
  • the side wall parts 6 and 7 forming the end faces consist of U-shaped plates of the above-mentioned material, the legs preferably overlapping the flat side wall parts 4 and 5 on the side facing the concrete.
  • assembly support parts 8 and 9 which consist of a U-shaped strip from one of the usual structural steel mats.
  • the webs 8a and 9a have approximately the width of the mold cavity 3 between the side wall parts 4 and 5 plus an addition for the wall thickness thicknesses of the side wall.
  • the legs 8b, c and 9b, c are preferably as long as the side wall parts 4 and 5 are wide.
  • Support elements 10 and 11 and spacers 12 are also provided for stiffening the side wall and for absorbing the concrete pressure.
  • the support elements 10 and 11 are designed as lattice girders and have three straight longitudinal rods 10a, b, c or 11a, b, c arranged in a triangle, one of the base rods 10a, b or 11a, b each having a zigzag bent rod 10d, e or 11d, e with the longitudinal rod 10c, 11c is connected to the ridge of the triangular cross section.
  • the spacers 12 usually consist of a tension rod 12a bridging the width of the mold cavity 3 and two fastening elements 12b, 12c, which are pushed through the plastic film at two opposite points of the side wall 2, for example the side wall parts 4 and 5, and on the outside of the side wall 2 be attached.
  • the formwork 1 is shown in the assembled state.
  • the assembly support parts 8 and 9 with their webs 8a and 9a are placed in parallel and in alignment with one another on a concrete base 13, so that the legs 8b, c, 9b, c point upwards.
  • the distance between the two assembly support parts 8 and 9 depends on the size of the molding space to be produced.
  • the side wall parts 4 to 7 are provided or bent in the desired size and arranged in the mounting support parts 8 and 9, respectively, that their free edges 4a, 5a, 6a and 7a are directed directly, ie without kinking, against the concrete base 13 .
  • the overlaps of the side wall parts 6 and 7 with the side wall parts 4 and 5 are expediently arranged in the region of the mounting support parts 8 and 9 and connected to the mounting support parts.
  • the spacers 12 can usually be anchored in the opposite side wall parts 4 and 5 and the support structure in the form of Support elements 10 and 11 are attached to the outside of the formwork wall 2.
  • Support elements 10 and 11 are attached to the outside of the formwork wall 2.
  • two supporting elements one at the top and one at the bottom
  • spacers 12 as required are preferably used on each longitudinal side.
  • the spacers 12 are pushed in the usual way through the plastic film and secured on the side of the side wall 2 facing away from the mold cavity 3 against slipping back, with either a lattice of the lattice work from the composite material and / or a lattice of the assembly support part 8 or 9 and / or a lattice bar of the support element 10 or 11 is gripped.
  • the support elements 10 and 11 are attached either to the assembly support parts and / or to the latticework of the composite material. When the formwork has been completed as shown in FIGS. 2 and 3, the concrete is filled into the mold cavity 3 from above.
  • the fastenings of the spacers 12 on the bars are removed and the projecting ends are cut off if necessary.
  • the support members 10 and 11 are removed after loosening their attachments and set aside for reuse.
  • the individual parts 4, 5, 6 and 7 of the side wall 2, possibly after a slight bending of the legs 8a, c, 9b, c of the assembly support parts 8 and 9 are removed from the finished concrete part and also set aside for reuse.
  • the assembly support parts 8 and 9 can be cut off and removed at the transition between the legs 8b, c or 9b, c to the web 8a or 9a.
  • the assembly support parts according to FIG. 4 can also be arranged with a web 8a, 9a pointing upwards, the free edges of the legs 8b, c, 9b, c standing on the concrete base 13 .
  • the further structure of the formwork is similar to the embodiment of FIGS. 1 to 3, so that reference can be made to the description there.
  • the arrangement according to FIG. 4 also effectively supports the side wall of the formwork, at least until it is completely assembled, so that no angling of the lower edges of the side wall is necessary to increase the stability.
  • the leg 8c in FIG. 4 it is possible in both exemplary embodiments to let the assembly support parts rest with their legs on the inner surface of the side wall facing the mold cavity.
  • the assembly support part can also be arranged crosswise, so that the side wall is supported on all four sides.
