Definitions

  • Holding anchor for connecting two separated by an insulating layer concrete slabs and at least these parts formed
  • the invention relates to a retaining anchor for connecting two concrete slabs separated by an insulating layer, which together form a concrete slab unit, wherein the retaining anchor consists of a flat steel and is U-shaped so that two legs connected by a connecting section are formed, which have a tip at their free ends and at least one suitable for receiving a reinforcing bar breakthrough is provided on each leg.
  • the invention further relates to a concrete slab unit, which is formed from the above-mentioned components.
  • Retaining anchors are used to make concrete slab units. The latter in turn are used in the construction sector.

  • the advantage of the solution proposed for the retaining anchor is that the bending strength of the legs is decisively increased by the introduction of at least one elevation per leg.
  • the flexural strength of the retaining anchor can be increased in a useful manner, if the elevations from the thighs continue in the connection section. As a result, a safe and accurate impact of the retaining anchor is guaranteed in an insulating layer.
  • the proposed solution makes it possible to maintain the previously chosen in practice material thickness in the retaining anchors and still achieve greater stability.
  • the decisive advantage is that the increase taken into account in the legs of the retaining anchors is continued in both concrete slabs. These elevations are thus not only in the area of the insulating layer, but they are continued with their end sections in the concrete slabs and poured into the two concrete slabs with. As a result, in addition to the tensile forces, above all, the pressure, bending and shearing forces that occur can be controlled much better than previously possible.

There are on the anchor anchor 1 at the top and bottom openings 13 for selectively receiving reinforcing bars 22 shown, see Fig. 5.

  • Each elevation 14 then has a rectangular shape with reference to FIGS. 1 and 2, or to FIGS. 3 and 4. It is also possible to provide instead of two elevations 14 only a single increase 14, starting from one of the two legs 3, and the connecting portion 2 completely claimant, to the other, ie second leg 3 is guided.
  • This single elevation 14 then has a U-shaped outline, cf. Fig. 1 and Fig. 3. It is possible in all the embodiments just described to dispense with the located near the connecting portion 2 openings 13, if this allows the number of required reinforcing bars 22. Also, the above-mentioned openings 13 may be passed through the at least one increase 14.

The same applies if the at least one increase is at least partially in the connecting section 2. The at least one elevation 14 is then either on the outside or on the inside. te of the connecting portion 2 is arranged. While in the exemplary embodiments described in FIGS. 1 to 4, the elevations 14 on the legs 3 are directed mirror-inverted from one another, elevations 14 located on the leg inner surfaces are directed mirror-inverted toward one another.
