Definitions

  • the invention relates to a device for transport anchors for precast concrete parts, wherein the transport anchor has a sleeve with an internal thread for a load suspension device.
  • Transport anchors are concreted into precast concrete, for example connected to the reinforcement of the precast concrete or anchored in another way in the precast concrete.
  • transport anchors consist of sleeves with an internal thread, which are accessible from the outside and into which a load suspension device, for example a rope eye, an eyebolt or the like, can be screwed.
  • the transport anchor is concreted into the precast concrete element, it is usually hardly visible from the outside. At most, a narrow ring-shaped outer surface can be seen, which, however, is extremely narrow due to the bevels at the outer end of the thread. If the transport anchor is therefore provided with a label that shows a load-bearing capacity, this label is usually unusable after installation.
  • the invention has for its object to provide a marking means on such transport anchors that remains visible in all operating positions, in particular even when the transport anchor is screwed in.
  • the marking means should not lead to a reduction in the load capacity of the lifting anchor. It should offer security against erroneous exchange and it should also be unmistakable in the formwork. Such a label should be cheap to manufacture.
  • the invention is based on a device of the type described in the introduction and suggests that the end of the sleeve facing the outer surface of the precast concrete element is surrounded by a clamping ring which bears a visible surface.
  • This clamping ring according to the invention can have a low overall height, so that it does not impair the support of the anchor sleeve on the concrete.
  • the clamping ring only extends in the area between the anchor sleeve and concrete, which does not contribute to the load-bearing capacity anyway.
  • the clamping ring which can be made of colored plastic, for example, and which can be a means of identification due to its coloring, an area which is always visible from the outside is obtained and which permits identification of the quality of the transport anchor in all operating positions. Contamination from concrete or cement milk is excluded or can be removed quickly and easily. Screwing in the load handler is not hindered.
  • the invention proposes that the inside diameter of a part of the clamping ring, which surrounds the anchor sleeve, is correspondingly adapted to the diameter of the anchor sleeve. This ensures that incorrectly marked clamping rings with an identification are also assigned to an anchor sleeve.
  • the visible surface can be designed like a tab. However, it is better if the visible surface is flange-shaped and the entire anchor sleeve is unspecified, so that any labeling on the clamping ring is visible from all sides.
  • the visible surface preferably has an inward projection, which is for example flange-like and forms a stop on the sleeve.
  • the correct arrangement is much easier in this way.
  • the part of the clamping ring surrounding the sleeve also has a claw-like or clip-like shape, which improves the adhesion to the sleeve.
  • Recesses are provided between the claws or clamps, which improve the elasticity of the claws or clamps and also form an anti-twist device in the precast concrete part.
  • the claws or clamps have inward projections, so that the clamping ring is deformed when installed.
  • outward projections are provided, which serve for anchoring in the concrete.
  • the clamping ring 5 has the visible surface 6, the inner area of which forms an extension 7 which bears against the end 3 of the sleeve 4.
  • This ring part 8 carries the claws or clamps 10 which have the inner projections 12 and the outer projections 13 at the inner ends 11.
  • the sleeve 4 sits at the end of a reinforcing bar 14 and has its end 3 facing the outer surface 1 of the prefabricated concrete part 2.
  • the clamping ring 5 can only be placed on a sleeve with the correspondingly adapted outer diameter. The clamping ring does not hinder the formwork process and cannot be lost or replaced after stripping.
