Abstract
A method for manufacturing a prefabricated concrete product is disclosed, in which method, a concrete slab with a recess at its upper surface is cast with slipform casting on a casting bed, and after the slipform casting of the slab the recess of the fresh cast slab is equipped with ducts, piping and/or wiring components, after which the recess is covered with concrete mass, and the concrete product is left to cure. The invention also relates to such a prefabricated concrete product.
Claims8
A method for manufacturing a prefabricated concrete product, comprising casting a concrete floor slab with a recess at its upper surface with a slipform casting on a casting bed, which recess, is defined by the a slipform casting mold and extends along the length of the slipform cast, wherein an area of the recess covers substantially whole of the upper surface of the slipform cast concrete slab with narrow raised portions defining the side surfaces of the recess, and that after the slipform casting of the slab, the recess of the fresh cast slab is equipped with ducts, piping and/or wiring components, after which, the recess is filled with a concrete mass, and the concrete product is left to cure.
A prefabricated concrete product, comprising a slipform cast concrete floor slab with a recess at the upper surface of the slab, which recess, is continuous along the length of the slab, wherein an area of the recess covers substantially whole of the upper surface of the slipform cast slab with narrow raised portions defining the side surfaces of the recess, and that the product comprises ducts, piping and/or wiring components installed in the recess at the prefabrication site, and a concrete layer cast to fill the recess and cover the components installed therein.
