Definitions

  • the invention relates to anchoring for Strands in concrete according to the preamble of claim 1.
  • Anchors of this type are e.g. for generation of prestressing used in concrete bodies. she usually include one lying on the concrete Anchor body, in which the strands in wedges be held. By pulling the strands Fastening wedges pressed together around the strands.
  • the anchor body therefore has one Base plate and a holding body, the base plate forms a shoulder to rest on the concrete and in Holding body the openings for receiving the fastening wedges are provided.
  • the base plate acts like a belt, that holds the holding body together. The from the wedges generated explosive forces can from the base plate to be caught.
  • ribs can be provided which extend from the holding body extend to the base plate.
  • ribs Preferably, at each opening (or at least some of the openings) Two ribs are provided. The two ribs extend outwards on both sides of the respective opening. They absorb the forces that the fastening wedge absorbs transmits the upper part of the opening.
  • the anchor can be a housing (trumpet) with an entry opening for the strands.
  • the Anchor body forms a space together with the housing, the strands run inside.
  • the housing can with a seal for the strands, so that strands can be used without bond.
  • the same housing is however also for a construction with Composite suitable if the housing with suitable connection means for an enveloping protective tube for the Strands is equipped.
  • FIG. 1 The basic structure of a preferred embodiment the anchorage according to the invention is shown in FIG. 1.
  • the anchor 1 is embedded in the concrete 2.
  • she has an anchor body 3, in which several on one Row lying, conical openings 4 are provided.
  • Fastening wedges 13 are known in the openings 4 Art arranged, each hold a strand 5 and through the pull of the strand can be compressed.
  • the bare ends the strands 5 lying in one plane extend through a trumpet-shaped housing 6 made of plastic an opening 7.
  • the strands 5 are included provide an enveloping protective tube.
  • Fig. 2 shows an embodiment of the anchor in a composite construction. It is different of the embodiment of FIG. 1 only in that No seal is provided in the area of the housing opening 7 is, but that there is an adhesive tape or a Shrink tube 9 a corrugated protective tube 10 connected is.
  • the strands 5 are open their entire length bare and the inside of the housing 6 and the protective tube 10 after tensioning with injection material, e.g. Cement mortar, filled.
  • injection material e.g. Cement mortar
  • the structure of the anchor body 3 is from the figures 3 to 5 can be seen. It is made of one casting Made of metal and consists essentially of one Base plate 15 and a holding body 16.
  • the holding body 16 is located in the center of the anchor body 3 and forms the openings 4 for the fastening wedges.
  • the base plate 15 extends around the holding body 16 and is much thinner than this. How especially out 3 and 5 can be seen, it divides the holding body 16 into approximately in two parts, so that the openings 4 from an area above the base plate to extend into an area below the base plate.
  • the base plate 15 acts thanks to this arrangement like a belt that the explosive counteracts the wedges.
  • the base plate 15 forms a shoulder 17a, 17b, which rests on the surrounding concrete. As from Fig. 3 shows the end regions 17a of the shoulder beveled. This causes the forces from the concrete generate a compression of the anchor body in the longitudinal direction, which is also the explosive effect of the fastening wedges counteracts in the middle.
  • each Ribs are arranged at each of the central openings 4. They extend from the center of the respective opening 4 towards the outside and absorb the lateral forces, that create the mounting wedges.
  • the base body can absorb very high forces. At the same time, it is light in weight and takes up little space.
