A method for the production of a concrete part, serving as a shaft bottom part or base of the shaft and apparatus for carrying out the method

摘要

A process for producing concrete mouldings, specifically shaft bases which are produced in a position inverted with respect to the use position, and a moulding device therefor are proposed. The special feature lies in the fact that, after the moulding process, the concrete part is demoulded in the same spatial position in which it was moulded and that, before the demoulding until setting of the concrete, the base of the concrete part is supported on the inside from below against falling in, the reaction forces being directed as compressive forces on the outside from above onto the outer edge region of the base and to the lateral walls extending therebeneath. The moulding device has, to this end, an inner supporting plate and an outer bearing plate which is laid on before demoulding and is connected to the supporting plate by means of a suspension mount.
