Abstract

The invention relates to building and can be used as a permanent formwork void former in the manufacture of reinforced concrete voided slabs. A permanent formwork void former comprises a hollow body provided with a spatial position fixing means and including conical supporting feet and at least one box-like member in the shape of a truncated pyramid, which is open at the large base end and has channels at the corners and also stiffening ribs for reinforcing the top side. The supporting feet are provided with fixing elements in the form of roughness or ribbing on their outer surface or in the form of an anchoring fastener, and the spatial position fixing means is in the form of depressions in the outer surface of the upper side of the box-like member, said depressions having protuberances for connecting adjacent elements of the permanent formwork to one another with the aid of couplings, which have recesses and openings for connection to the corresponding protuberances in the indentations of the box-like member.
