Definitions

  • the invention relates to a formwork for foundation parts of the type explained in the preamble of claim 1.
  • Such formwork is known from DE-OS 34 36 690.
  • the known formwork consists of a U-shaped strip from a latticework shrunk with plastic film and forms a channel with vertical side walls into which the concrete is poured from above.
  • the cross-section of the finished foundation is thus constant over the entire height of the foundation part, the width of the cross-section over the entire height of the foundation part corresponding to the width of the standing area necessary for the corresponding floor conditions.
  • the supports or the wall receiving surface of the foundation part must theoretically only be so large that supports or wall can lie snugly.
  • the invention is based on the object of providing a formwork which avoids an additional consumption of concrete at low labor costs.
  • the design according to the invention creates a formwork that is just as easy and inexpensive to handle as the formwork of the prior art, but requires significantly less concrete. Due to the flexibility of the latticework shrink-wrapped with plastic film, cross-sectional shapes can also be produced which cannot be manufactured with conventional formwork means, for example boards, or only with an unacceptably high amount of work. Examples of this would be inconsistently tapering or irregular cross sections.
  • Claims 2 and 3 describe the application of the invention to a lost (claim 2) or removable and reusable (claim 3) formwork.
  • a lost formwork 1 for production of a strip foundation can be seen, which is designed as a channel with two lateral formwork walls 2 and 3 forming the long boundaries of the channel and a formwork floor 4.
  • the side formwork walls 2, 3 and the formwork floor 4 are integrally bent from a strip of composite material, which consists of a latticework 5 and a plastic film 6 shrunk onto the latticework 5 on both sides.
  • the latticework 5 is preferably one of the usual structural steel mats of suitable strength with crossed transverse or longitudinal bars 5a, 5b.
  • the plastic film 6 is one of the usual shrink films of suitable strength, such as can also be used for packaging purposes, for example.
  • the plastic film 6 was placed in two webs, 6a, 6b on both sides of the still flat latticework 5 and shrunk under the action of heat, so that it closes tightly around the rods 5a and 5b due to the associated contraction and both layers 6a, 6b through the Openings of the latticework 5 are interconnected. Then the latticework 5 with the shrunk-on plastic film 6 is bent to the desired profile.
  • the formwork was designed in such a way that the completely cast foundation part is provided in the lower region 7a in the form of a plate with an elongated rectangular cross section and in the upper region 7b above it with a trapezoidal cross section tapering upwards.
  • the floor width b 1 is determined according to static aspects depending on the formwork length l, while the reduced upper width b 2 is coordinated with the necessary footprint for the supports or walls.
  • stiffening elements 8 and 9 are arranged in the vicinity of the upper edges of the side formwork walls 2 and 3, which consist of three straight longitudinal rods 8a and 9a and triangular longitudinal rods assembled in a triangle 8b, 9b exist, the curved longitudinal bars 8b, 9b each connecting two of the straight longitudinal bars 8a and 9a. Only two curved longitudinal bars 8b and 9b can be provided per stiffening element 8 and 9, respectively.
  • the stiffening elements 8 and 9 are preferably attached to the side walls 2 and 3 with the aid of a spacer 10.
  • the spacers 10 penetrate the plastic film 6 and encompass both a transverse or longitudinal rod 5a or 5b of the lattice work and one of the longitudinal rods 8a or 9a of the stiffening elements 8 or 9 using suitable, known connecting means, in the simplest case, wire wire.
  • These spacers 10 ensure that both the width b2 of the upper opening of the formwork 1 and the distance between the formwork walls 2 and 3 remain essentially unchanged over the entire height of the formwork walls.
  • the narrow sides of the formwork 1 can be closed with suitable pieces of material. Suitable for this are both conventional formwork boards and a correspondingly cut and fastened piece of the material also used for the formwork 1, made of latticework shrunk with plastic film.
  • FIG. 3 shows a section similar to FIG. 2 through a further exemplary embodiment of the invention in the form of a reusable formwork 11.
  • the formwork 11 consists of at least two opposing formwork walls 12 and 13, each of which is made from a cut strip of the formwork already used for the formwork 1 used, shrunk with plastic film 6 latticework 5 exist. Thereafter, the two side formwork walls 12 and 13 were bent step-like and fixed in mirror image and by means of the spacers 10 already described and in a predetermined distance in parallel to each other and placed on a concreting base 14.
  • the greatest width b1 of the formwork 11, the width of the floor area, is in turn based on the static conditions, while the width b2 on the top of the formwork 11 is adapted to the required footprint for supports or walls.
  • the cross section of the foundation part produced with the formwork 11 thus has a plate-shaped lower region 15a with an elongated rectangular cross section, a central region 15b with a trapezoidally tapering cross section upwards and an upper region 15c, which in turn is plate-shaped but with a shorter rectangular cross section is.
  • stiffening elements 8 and 9 can also be provided here, which have been omitted from the drawing for reasons of clarity.
  • the formwork 11, like the formwork 1, can also be closed on its narrow sides.
  • the fastenings of the spacers 10 with the formwork walls 12 or 13 are loosened (when using wire, this is pinched off), so that the formwork walls 12 and 13 and possibly also the formwork walls not shown, covering the narrow sides can be removed after the concrete has hardened.
  • the formwork can easily be can also be designed as formwork for individual foundations. Due to the flexibility of the latticework, the cross-sectional shapes of the achievable foundation parts are essentially freely selectable, so that they can be adapted to the structural conditions and the calculations without a noticeably increased amount of work, as would be the case with conventional formwork. If necessary, a latticework that is only shrunk on one side with plastic film can be used if the expected corrosive loads allow it. All known types can be used as spacers or stiffening elements.
