  • a lifting device consisting of an anchor bolt intended for concreting in heavy loads, which is provided with a temporary component in the precast concrete part, preferably made of elastic material, in particular rubber or elastic Plastic, existing recess body is built into the heavy load, and a connector for connecting the anchor bolt to the lifting gear, which engages behind and integrally forms a connecting head formed on the anchor bolt, consist
  • the aim of the invention is to achieve a further improvement of this device, in particular with regard to its load absorption or load transmission properties.
  • This is achieved according to the invention in the device specified at the outset by providing at least two diametrically opposed, approximately perpendicular to the bolt axis and parallel to each other crescent-like crescent-shaped grooves in the connecting head of the anchor bolt, in which the connector with its runners can be hung, the bolt axis Closer walls of the sickle-like grooves (groove base) running parallel to the bolt axis are flat.
  • This configuration in particular in the case of an inclined pulling direction, as can be seen e.g. when setting up the precast concrete results, the force transmission into the precast concrete part is secured and the same is prevented from flaking off at the force application points. This will be explained in more detail later.
  • an expedient embodiment of the invention is characterized in that the shank of the anchor bolt has an elliptical cross-section and optionally has a widening on all sides at its end remote from the connector in a manner known per se.
  • the connecting head of the anchor bolt can be provided on the side of the sickle-like grooves facing away from the connecting piece with a transverse hole which runs preferably perpendicularly to the groove base of the sickle-like grooves and is in a manner known per se approximately perpendicular to the bolt axis.
  • a reinforcement bar can be inserted through this hole to better transfer the loads from the anchor bolt to the precast concrete.
  • the recess body which is split in the middle in a known manner and can be opened, has a cavity in its interior which is designed as a negative form of the connecting head of the anchor bolt and in particular is provided with two sickle-like projections penetrating into the sickle-like grooves of the connecting head .
  • FIG. 1 shows an axial section through a device for transporting and manipulating prefabricated concrete parts known from AT-PS 358 788, the connector of which can also be used, for example, in the device according to the invention
  • FIG. 2 shows a view of the object from FIG. 1 from the direction A with the precast concrete part removed and the adjusting lever arm pivoted up to illustrate the connection piece which can also be used in the device according to the invention
  • FIGS. 3 and 4 are views of the anchor bolt according to the present invention from two directions offset by 90 °
  • FIGS. 5 and 6 are two sectional views along mutually perpendicular planes through a recess body according to the present invention
  • FIGS. 7 and 8 two schematic sectional representations along mutually perpendicular planes in order to explain the application of force in the device according to the invention.
  • the device consists of an anchor bolt 3 with a shank 4 and connecting head 5 set up for concreting into the precast concrete part 1 and a spherical connecting piece 6 which can be connected thereto and from which a manipulating arm 7 projects.
  • the connector 6 has an arcuate slot groove 8, the projecting edges or runners 8a (cf. in particular Fig. 2) engage behind the connecting head 5.
  • the slot groove 8 is adapted in cross section to the shape of the connecting head 5 or the crescent-shaped grooves formed therein (cf. FIGS. 3,4 and 7,8).
  • the slot groove 8 has at its end an insertion recess 9 for the connecting head 5.
  • the shaft 4 of the anchor bolt 3 is guided in the slot 10 of the slot groove 8.
  • the connecting piece 6 has a central articulated bore 11 which runs essentially perpendicular to the plane of the slot groove 8 through the center of curvature 12 thereof.
  • a shackle 13 is used for attaching the hoist. This passes through a part of the articulated bore 11.
  • the manipulator arm 7 has nothing to do with the lifting gear striking, rather it functions as an adjustment arm for the insertion recess 9 of the slot groove 8; it is also oriented accordingly and can be pivoted through the towing shackle 13, as indicated by the bow arrow in FIG. 1.
  • the articulated bore 11 has bevels 14, which allow movement of the trailer shackle 13 in the articulated bore 11 without further ado, etc. in different directions.
  • Fig. 3 shows a view of the anchor bolt 3 according to the invention perpendicular to the course of the crescent-shaped grooves 15 formed in the connecting head 5 and Fig. 4 shows a view from a direction rotated by 90 °, i.e. in the direction of the course of the grooves 15.
  • the connecting head 5 consists of a cylindrical part which tapers towards the shaft 4 in the shape of a truncated cone.
  • two horizontal, sickle-like grooves 15 are provided opposite each other with respect to the pin axis 3a, which run approximately perpendicular to the pin axis 3a.
  • the walls (groove base) 15a of the sickle-like grooves 15 running parallel to the pin axis 3a are flat.
  • the connector 6 is suspended with its runners 8a in the sickle-like grooves 15 of the anchor bolt 3.
  • a plate-like connecting head 5a is thus formed above the grooves 15 for forwarding the load from the anchor bolt 3 to the connector 6 and finally to the lifting device, not shown.
  • the connecting head 5 is provided with a transverse hole 16 lying approximately perpendicular to the pin axis 3a, which advantageously runs perpendicular to the groove base 15a of the crescent-like grooves 15.
  • a reinforcing bar 17 (see FIGS. 7 and 8) can be inserted through this transverse hole 16 in order to be able to better transmit the load from the anchor bolt 3 to the precast concrete part 1.
  • the lower bottom of the transverse hole 16 can, like indicated at 16a, to be sloping outwards in order to better adapt to any curvature of the reinforcing bar 17.
  • the lower third of the connecting head 5 consists of the conical transition to the shaft 4, which can optionally be formed with an elliptical cross section.
  • a conventional truncated cone-shaped widening 18 on all sides is used, which also serves as anchoring means in the concrete.
  • Such recess body 19 are firmly attached to the inside of the formwork for the future precast concrete part 1.
  • the formwork is loosened and the recess body 19 is removed from the finished prefabricated concrete part 1, so that a recess corresponding to the negative shape of the recess body 19 is formed on the concrete surface for the purpose of attacking the connector 6 on the head 5 of the anchor bolt 3 (cf. Figs. 1,7,8).
  • the hemisphere is cut along the middle connecting plane perpendicular to the flats 20 (at 22 in FIG. 5), so that the recess body 19 can be opened in order to be able to accommodate the upper part of the head 5 of the anchor bolt 3 in its interior.
  • a cavity 23 is formed, which is designed as a negative shape of the connecting head 5 of the anchor bolt 3, and which in particular has two sickle-like projections 24 penetrating into the sickle-like grooves 15 of the connecting head 5. At least the upper section of the connection head 5 is thus completely surrounded by the recess body 19 (or fills the cavity 23 of the recess body 19).
  • Holes 26, 27 are provided in the base surface 25 of the recess body 19, which are used to fasten the recess body to the formwork or Remove from the precast 1 serve.
  • the anchor bolt 3 is installed in the precast concrete part 1.
  • the anchor bolt 3 is placed with its connecting head 5 in the hinged recess body 19.
  • a corresponding reinforcing bar 17 is inserted through the transverse hole 16 of the anchor bolt 3 (if necessary).
  • the anchor bolt 3 is held firmly and securely in its position so that it cannot shift or shift when concreted in.
  • the recess body 19 is removed from the prefabricated concrete part 1 (for example, by pulling out or levering out by means of the holes 26), as a result of which a recess in the form of a laterally flattened hemisphere for receiving the connecting piece 6 when coupling the precast concrete part 1 to the hoist.
  • the connector 6 will move in the pulling direction until the runners 8a of the connector 6 lock in the grooves 15 of the anchor bolt 3, ie until on the one hand the runners 8a with their outside below Support on the cylindrical middle part of the connection head 5 - see Circle B in FIG. 7 - and on the other hand the runners 8a rest with their inside on the underside of the plate-like connecting head 5a - see circle C in FIG. 7.
  • the vertical force is also at C, but over a somewhat wider area on the underside of the plate-like connecting head 5a via the remaining web between the grooves 15 or their flat groove base walls 15a via the shaft 4 and the widening 18 initiated in the concrete of the prefabricated part 1.
  • the horizontal force component Y H is broken down into a compressive force between the concrete and the connecting piece 6 at D, into a compressive force on the web remaining between the grooves 15 at F and a tensile force in the mentioned web of the anchor bolt 3 at E.
  • the compressive force on the concrete at D is adequately secured with enough concrete in the Y direction.
  • the vertical force component Y V is introduced into the concrete of the precast element 1.
