Definitions

  • the invention relates to a screwable lifting device for conveying a solid body by means of releasable connecting elements which are dependent on the lifting gear, with at least two lifting devices being attached to the body for positionally stable transportation and each lifting device being supported on the surface of the body via a pressure plate.
  • Known lifting devices of this type which are screwed into floor groups of concrete bodies for lifting and lowering them by means of lifting devices, namely in flush-cast threaded bushes welded to the steel reinforcement of the concrete bodies, are closed eyelets with molded pressure plates and screws which are made from one piece consist.
  • the eyelets For the immediate insertion of hooks or shackles, the eyelets must either be sized appropriately, or ropes must be threaded into small eyelets and then formed into figure-eight loops in which the hooks or shackles can be hung.
  • Such lifting devices are special constructions, which are also still relatively expensive, so that after they have been transported they have to be removed from the bodies and returned for reuse. In many cases the acceptance or at least the return of these lifting devices is omitted.
  • the invention has for its object to provide a lifting device of the type mentioned, which is simple to manufacture and can be manufactured with simple means, if necessary, at the place of use.
  • the lifting device is in several parts and from a head screw protruding from the body in the screwed-in state, a thrust washer penetrated by the screw, and a support tube for the thrust pipe surrounding the screw with an axial gap surrounding it assigned connecting member and a pressed against the support tube, penetrated by the screw and supported on the screw head, protruding transversely to the longitudinal axis of the screw over the support tube for the connecting member.
  • the concrete body 1 in the floor area 1A has cast-in at several distributed locations and with the reinforcement 2 anchored threaded bushings 3, which are flush with the outer wall and serve to accommodate screwable lifting devices.
  • Each lifting device is formed in several parts from conventional elements and can therefore be easily manufactured if necessary at the charging point of the concrete body. For this purpose, only one head screw 4, in particular a standardized hexagon screw, can be screwed into the threaded bushing 3 for each lifting device.
  • the securing part 6 can consist of a flat bar which projects beyond the rope loop 9 and projects beyond the end face of the support tube 7 on all sides.
  • the screw head 4A optionally engages via a washer 5 on the securing part 6 and presses the supporting tube 7 firmly against the thrust washer 8 when the screw 4 is screwed into the threaded bushing 3 via the securing part 6, so that the supporting tube is subjected to a bending stress when the concrete body 1 is raised and lowered prevents the screw 4, which is thus only exposed to shear stress.
