    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.
