Abstract

A method for arranging engagement means in a concrete body. These engagement means can come into contact with securing means, resulting in a coupling of considerable strength between the concrete part and the said securing means. The engagement means may comprise a screw thread, bayonet-like structure or the like arranged in the concrete. However, it is also possible for the engagement means to be designed as a separate component which is placed into the concrete material. This separate component is then provided with the engagement means proper in that it is provided with a screw thread, bayonet catch or the like. In this way, it is possible to secure construction parts to the concrete part, to hoist the concrete part and to carry out further actions with this part. It is also possible to adjust the concrete part with the aid of adjustment bolts which engage in the engagement means.

Claims

1-19. -19. (canceled)

20. A method for arranging engagement means in a concrete part, comprising the steps of:

providing a body whose exterior comprises an elastomer material, with mechanical properties which are such that there is a considerable reduction in the external diameter at removal from the concrete;

providing a formwork, arranging said body at the formwork surface, encasing said body in concrete material and removing it from the concrete after setting and removal of the formwork, said body being elongate and is removed from the concrete in its longitudinal direction and is provided with a projection which, at a distance from its end located at the boundary surface of the concrete, is positioned transversely with respect to the longitudinal direction and leaves behind a non-release recess in the concrete after setting, which recess comprises securing means for an engagement part which is then fitted into the concrete, wherein said body comprises a core, wherein said core is relatively rigid, comprises a supporting surface and is self-supporting and is secured to said formwork.

21. The method as claimed in claim 20, wherein said projection comprises a continuous surface designed in such a manner that it is able to absorb both tensile and compressive forces.

22. The method as claimed in claim 20, wherein said securing means comprise a screw thread-like recess in the concrete material and the engagement part is designed accordingly.

23. The method as claimed in claim 20, wherein said securing means comprise a bayonet-like recess in the concrete material and the engagement part is embodied accordingly.

24. The method as claimed in claim 20, in which said securing means are arranged on/in front of the said body, which securing means remain in the recess when said body is removed.

25. The method as claimed in claim 20, wherein the said engagement part comprises hoisting means.

26. The method as claimed in claim 25, comprising the step of providing a cavity which at both ends open out at the same boundary surface of the said concrete part, which cavity is U-shaped and is designed to receive a hoisting feature.

27. The method as claimed in claim 20, wherein the said engagement part comprises an (adjustment) bolt.

28. The method as claimed in claim 27, in which the said bolt comprises concrete material.

29. The method as claimed in claim 20, wherein the said core, because of its shape and configuration, gives space to the wall thereof.

30. The method as claimed in claim 20, wherein the said core is separated from the said elastomer material when the body is removed from the concrete.

31. The method as claimed in claim 20, comprising the step of providing a series of bodies which are secured to a common carrier.

32. The method according to claim 20, wherein a series of engagement surfaces is arranged in a concrete part, which extend from an outer wall thereof, comprising the steps of, placing a series of bodies into said formwork, wherein each cavity comprising a blind bore.

33. The method as claimed in claim 20, wherein said securing means comprise a metal part which absorbs tensile and/or compressive forces and extends over the entire extent of the concrete part in the transverse direction.

34. The method as claimed in claim 20, wherein said concrete part is moved to the building site after said recess has been put in place.

35. The method as claimed in claim 20, wherein said body can be removed by hand.
