Definitions

  • the invention relates to a transport anchor for precast concrete parts with an anchor head intended for connection to a stop head and connected to an anchor shaft.
  • Transport anchors of this type are used to attach precast concrete parts to hoists during transport and handling on the construction site.
  • the stop head connected to the hoist has, for example, a threaded pin which can be screwed into a threaded sleeve forming the anchor head of the transport anchor.
  • the stop head designed as a stop eye has claws engaging behind the anchor head (DE-PS 1 684 278).
  • transport anchors of the type mentioned at the outset are designed as expansion anchors or plate foot anchors with thickened or widened to a plate anchor foot, which be anchored in the precast concrete part works. When loaded up to breakage, these lifting anchors usually cause a wide breakout cone. Therefore, these transport anchors can often not be used in thin components, especially in thin-walled precast concrete parts, in which the transport anchor protrudes into narrow webs lying between adjacent cavities and must be anchored there.
  • the object of the invention is therefore to provide a transport anchor of the type mentioned, which enables secure anchoring even in thin-walled webs or the like.
  • the rod-shaped anchor shaft is provided with ribs on its outer surface.
  • the force exerted on the transport anchor is introduced into the surrounding concrete over the entire length of the anchor shaft, so that an approximately equal force transmission is ensured even with thin components.
  • Similar to rebar, which is used as reinforcement, the force transmission between the lifting anchor and the concrete is approximately uniform over the entire length of the anchor shaft.
  • the transport anchor shown in Fig. 1 has a rod-shaped anchor shaft 1, the outer surface of which is provided in the manner of a concrete rib steel with ribs 2, 3, the ribs 2 being coiled over the entire length of the shaft, while the short ribs 3 approximate each other at a distance extend across the aisles of the ribs 2.
  • rib shapes can also be used, which can also be formed, for example, by grooves or other depressions rolled into the outer surface of the anchor shaft.
  • the anchor shaft 1 has an upset shaft head 4, which is provided with an external thread, onto which a threaded sleeve 5 is screwed, which projects beyond the shaft head 4.
  • the part of the threaded bore 6 of the threaded sleeve 5 that remains free serves for screwing in a threaded pin attached to a stop head (not shown).
  • the lifting anchor closes approximately flush with the bottom of a recess 7 in the outer surface 8 of a precast concrete element.
  • the transport anchor was cast into the precast concrete during manufacture. After screwing in a stop head, the lifting anchor is used to guide the forces exerted by the stop head during transport and handling of the precast concrete into the precast concrete.
  • the power transmission takes place almost exclusively on the entire, ribbed outer surface of the anchor shaft 1.
  • one or more pressings 9 have been made from the outside of the threaded sleeve 5 after screwing, by means of which the material of the threaded sleeve has been pressed against the external thread of the shaft head 4 in order to loosen the screw connection to prevent.
  • the anchor shaft 1 which is otherwise designed in the same way as in the example according to FIG. 1, is provided in one piece with an upset, essentially plate-shaped or mushroom-shaped anchor head 10, which in a hemispherical depression 11 in the outer surface 8, which is only indicated by dash-dotted lines of the precast concrete protrudes and can be engaged there by a stop head (not shown).
  • FIG. 3 shows a fastening option for the threaded sleeve 5 that is modified compared to FIG. 1.
  • the threaded sleeve 5 has an inwardly projecting bead 12 on its shaft-side end.
  • the shaft Kops 4 is pressed into the bore of the threaded sleeve 5 and is supported on the bead 12 in the event of an axial tensile load.
  • Fig. 4 shows another embodiment in which the anchor shaft 1 has a circumferential bead 13 at its head end, over which the threaded sleeve 5 is pressed, so that the anchor shaft 1 is anchored in the threaded sleeve 5 by the bead 13 surrounded on all sides by the threaded sleeve 1 is.
  • a shank head 4 which is preferably upset is screwed into the threaded sleeve 5 at one end.
  • the shaft head 4 is connected to the threaded sleeve 5, however, by a weld seam 14 arranged at the shaft-side end of the threaded sleeve 5, which is essentially used to secure the screw connection between the shaft head 4 and the threaded sleeve 5.
  • the armature shaft 1 is provided at its head end with an external thread 15, onto which the armature head 10 ′, which is of annular design, is screwed.
  • a modified embodiment is. in Fig. 7 shown.
  • the anchor shaft 1 protrudes into a bore in the likewise annular anchor head 10 ′′ and is connected to it by a weld seam 16 arranged on the end face, which preferably runs flush on the outside of the head.
  • all parts of the transport anchor are made of steel, for example structural steel or stainless steel. Instead, it is also possible to manufacture individual or all individual parts of the transport anchor from a different material, for example plastic.
