Definitions

  • the present invention relates to a spacer for reinforcement elements of concrete structures according to the preamble of claim 1.
  • spacers are usually used for creating concrete coverings, for example floors or ceilings, and serve as a support for the reinforcing bars.
  • the spacers must provide secure support for the reinforcement elements and are particularly exposed to treading when walking on the reinforcement.
  • the widely used metal spacers are less and less able to meet the increasingly stringent requirements for corrosion resistance, so that plastic spacers are becoming increasingly popular.
  • the concrete cover is poured in such a way that the underside of the spacers is visible. With many concrete coverings that are subsequently coated, whether by painting or mortar or the like, this does not play a major role, while this is unacceptable for concrete structures that are no longer coated. Based on this, in a further development of the invention, the lower part of the trestle, up to the crossbar thereof, is poured with concrete.
  • the carrier 1 according to FIG. 1 has a double-T profile, this carrier being shown upside down in FIG. 1 and also being used in this way.
  • This double-T profile consists of a web 2, at the foot end of which the wider foot beam 3 and in the upper half of the narrower cross beam 4 is arranged.
  • the head end 5 of the web forms the support for the reinforcement elements.
  • the carrier 1 can be efficiently made from a suitable plastic.
  • the trestle 6, seen from the side has the shape of a large A and has a crosspiece 7 approximately in its center, as a result of which the upper part of the trestle forms a push-through opening 8 for the support 1.
  • Both the foot bar 3 and the cross bar 4 have a length adapted to the push-through opening 8, the cross bar 4 being somewhat longer than the clear width of the push-through opening 8 at this point. This achieves a clamping effect that prevents the trestle from moving freely on the carrier, but on the other hand enables it to be attached without excessive resistance.
  • a further easing of the mounting of the trestles, which can take place automatically, is ensured by the fact that the upper side 9 of the three walls 7 and 13 of the push-through opening, see FIG. 3, is not flat, but rather, seen in the longitudinal direction of the carrier the two outside sides of the trestle.
  • the crossbar 7 is adjoined at the bottom by two feet 10, each of which has a central wall 11 in the present exemplary embodiment in order to increase the stability.
  • a connection web 12 between the two feet also serves to increase the stability.
  • a certain spacer with a certain distance between the not shown shell boards and the not shown reinforcement elements was shown in such a way that the push-through opening 8 and the feet have approximately the same height.
  • the same support can be chosen for all the distances between the formwork and reinforcement elements, which requires the same through opening 8, while the length of the feet 10 can be produced in the desired and required lengths by the generally standardized To produce heights of the spacers. Due to the particularly stable construction of the trestles, it is possible to use recyclable plastic.
  • the lower part of the trestle 15 is cast and poured with concrete 16 according to the embodiment of FIG. 5.
  • This concrete not only enables a very good connection between the spacer and the concrete structure, but also an extensive adaptation to the concrete structure in order to differentiate little or not at all from the underside of the spacer from the structure to be created.
  • a spacer with trestles with a concrete lower part offers even more security against increased tread load.
