Definitions

the invention relates to an anchor for transporting and manipulating heavy loads, in particular precast concrete parts, by means of a lifting device, consisting of an anchor bolt and an anchor head and optionally a widened anchor base.
Such anchors are widely used in connection with manipulation and lifting devices, as are known for example from AT-PSs 283 691 and 358 788.
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.
the anchor bolt is provided in its third of its longitudinal extension adjoining the anchor head with a known thickening of the approximate shape of a cylinder, the axis of this cylinder being approximately perpendicular to the anchor bolt axis arranged and this cylinder is provided in the direction of its axis with a preferably circular transverse hole.
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 bolt a cross hole is provided with an 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.
the invention furthermore relates to a lifting device concreted in a precast concrete part using an anchor according to the invention, which is characterized in that a reinforcing bar in the form of a U or V is guided through the transverse hole of the anchor bolt in a manner known per se and that the apex of this Reinforcing iron is provided with a bend or angled so that a plane through the two legs of the U- or V-shaped reinforcing iron is at a distance from and parallel to the anchor bolt.
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 runs in the direction of the axis 5 ⁇ .
This transverse hole 6 serves to receive an additional reinforcement (concrete iron) 7, 7A as is 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 precast 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 bar 7A has a bend or angled so that a plane through the two legs 7A ⁇ of the reinforcing bar 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.
