Definitions

  • the invention relates to a concrete anchor made of a flat steel part for precast concrete parts with an anchoring area in the precast concrete part and a connection area lying in the surface area of the precast concrete part.
  • Such an anchor is known as a set-up and transport anchor from DE-AS 27 04 435.
  • the anchoring area is designed in such a way that the lower end of the anchor is slotted in the middle and the two halves are bent apart in opposite directions, so that expansion legs are created.
  • the object of the invention is to improve its load-bearing capacity without increasing the manufacturing outlay.
  • the anchoring area is formed from a hook-like, alternate bend at the end of the flat steel part from the longitudinal direction of the anchor, so that at least two support areas lying essentially transverse to the direction of stress are created on both sides of the longitudinal axis of the anchor.
  • the loading point is at the same tie-in depth of the anchor in this embodiment of the anchoring area lower than in the above-mentioned anchor according to the prior art of the technique.
  • the distance between the stress point and the surface of the precast concrete element is included in the calculation of the load-bearing capacity of an anchor.
  • the offset of the load areas in the tie-in depth also leads to a favorable distribution of the load.
  • the supporting areas running according to the invention also allow a better introduction of force into the surrounding concrete of the precast concrete element (reduction of splitting tensile stress) while at the same time lower surface pressure, since compared to the anchor according to the prior art, the supporting area has twice the anchoring area (in the projection direction) and in that of the Anchor side immediately adjacent area, which is crucial for the load-bearing capacity.
  • An embodiment of the invention provides that the curvature of the flat steel part in the anchoring area is selected such that a reinforcing bar can be inserted.
  • This configuration enables a far-reaching introduction of force into the precast concrete part and thus improves the structural properties of the anchor.
  • Another embodiment provides that the end face of the end of the anchoring area has a complementary shape to the end face of the end of the connection area. This has the advantage that no material loss occurs, since several anchors can be separated from a corresponding flat steel rod by a cutting tool.
  • the design according to the invention of the anchoring area of the anchor means that there are no restrictions for the required design of the coupling area as it is is proposed for example in the above-mentioned DE-AS.
  • the anchor 10 consists of a flat steel part which is embedded in a prefabricated concrete part 20.
  • it essentially consists of a connection area protruding from this precast concrete part 20 and an anchoring area lying in the precast concrete part 20.
  • This anchoring area is designed according to the invention so that two support areas 11 and 12 are formed, which lie on both sides of the anchor axis aa and take the load of the precast concrete part 20. It has been shown that the point of maximum stress on the concrete lies approximately at the level of the lower supporting area 12, and thus reaches the lowest point imaginable, in other words: practically the entire embedment depth L of the anchor 10 can be included in corresponding calculations for the dimensioning of the load-bearing capacity.
  • this hook-like bend in the anchoring area can be carried out in one operation simply by cold working the flat steel part.
  • a reinforcing bar 15 is inserted into the inner curvature of the resulting hook.
  • the maximum lateral dimensions x and y of the two treg regions 11 and 12 are selected to be of the same size (exemplary embodiment in FIGS. 1 and 2).
  • the coupling area of the anchor in question has a roof-shaped configuration or a configuration such as is given in the above-mentioned DE-AS, it is advantageous to give the negative shape of the end face 14 of the coupling area to the end face 13 of the anchoring area, since then only one Cutting tool to separate the anchors from a flat steel rod is required.
  • the total length of the armature 10 can then be determined such that the projection area of the two support areas 11 and 12 are of the same size despite the specially shaped end faces 13.
  • the anchor according to the invention thus combines the advantages of simplest manufacture with a favorable load-bearing capacity.
