Definitions

  • the invention relates to an anchor for transporting and manipulating heavy loads, in particular precast concrete, by means of a lifting device consisting of an anchor bolt and an anchor head, the anchor bolt being provided in its longitudinal extension with a thickening of the approximate shape of a cylinder, the axis of this cylinder arranged approximately perpendicular to the Anherbolzen axis and this cylinder is provided in the direction of its axis with a preferably circular transverse hole.
  • Such anchors are widely used in connection with manipulating and lifting devices, as is known for example from DE-B-2 223 519.
  • the aim of the invention is to improve such an anchor in such a way that a better introduction of the forces into the heavy load, in particular the prefabricated concrete parts, and that, above all, a better absorption of the splitting tensile forces during installation and avoidance of flaking is achieved.
  • This is particularly the case with thin precast concrete parts, with low concrete strength, with lightweight concrete as well as with leca, slag and sludge concrete or the like. essential.
  • an anchoring device for concrete components which has a connecting element for establishing the connection with a transport device, for example a hoist, and an anchoring element for anchoring in the concrete component, in which at the upper end of a shaft-like connecting member or Bolzens a cross hole is provided with inserted cross bar, but this cross bar, in contrast to the present invention, serves as a connecting element for establishing the connection with the transport vehicle thus as an anchor head;
  • a forged cross bar is provided at the lower end of the bolt and serves as an anchor base.
  • FIG. 1 shows a view of the anchor according to the invention
  • FIG. 2 shows a view of the anchor rotated by 90 ° with respect to FIG. 1, partly in section
  • FIG. 3 shows a sectional view along the line III-III in FIG. 2
  • FIG. 4 shows a top view of the anchor in the position according to FIG. 2
  • FIG. 5 shows a sectional view along the line VV in FIG. 1
  • FIG. 6 shows a section through a plate-shaped prefabricated concrete part in the plane of its largest dimensions at the location of the anchor
  • FIG 7 shows an analog section along a plane rotated by 90 ° with respect to FIG. 6,
  • FIG. 8 shows a section corresponding to FIG. 7 with another reinforcement insert
  • FIG. 9 shows a section corresponding to FIG. 6 with the reinforcement insert according to FIG. 8.
  • 1 denotes the anchor as a whole, it consists of an anchor bolt 2, an anchor head 3 for attacking a known lifting device, not shown, and optionally a widened anchor base 4.
  • the anchor bolt 2 is provided with a thickening 5 which is approximately cylindrical; the axis 5 'of this cylinder runs approximately perpendicular to the axis 2' of the anchor bolt 2 (see. Fig. 2).
  • This cylindrical thickening 5 is provided with a preferably circular transverse hole 6 which extends in the direction of the axis 5 '.
  • This transverse hole 6 serves to receive an additional reinforcement (concrete iron) 7, 7A as shown in FIGS. 6 to 9, for example.
  • the diameter of the cylinder forming the thickening 5 is expediently approximately twice the diameter of the anchor bolt 2 and the height of this cylinder corresponds approximately to the diameter of the anchor bolt 2.
  • FIGS. 6 to 9 show installation examples of the anchor 1 according to the invention in a plate-shaped prefabricated concrete part 9; the upper part of the anchor bolt 2 protrudes with the anchor head 3 into a hemispherical recess 8 on an end face of the precast concrete part 9, which is provided in a known manner for engaging the connecting head of the lifting device on the anchor head 3.
  • the additional reinforcement (concrete iron) 7A inserted through the transverse hole 6 in the anchor 1 is also U-shaped or. Is bent in a V-shape, but the apex 7A 'of this reinforcing iron 7A has an offset or angled so that a plane through the two legs 7A ⁇ of the reinforcing iron 7A is at a distance from the anchor bolt 2 and parallel to it.
  • the precast concrete part 9 is expediently set in the direction of arrow A in FIG. 8.
