Abstract

A pre-fabricated component for hollow reinforced concrete consists of a long substrate, at least two longitudinal vertical walls on the substrate to form a whole body, in parallel or crossed. At least two hollow over-linked bodies and/or fillers lighter than concrete are arranged on the substrate. At least one lateral supporting is located between the said vertical walls, and connected with them and the said substrate. The hollow over-linked bodies and the lighter fillers can reduce amount of concrete cast in site so as to reduce the weight of the pre-fabricated component, to reduce cost, and to increase strength of the hollow component. It is used for lightweight plate of reinforced concrete cast in site or pre-stressed reinforced concrete, hollow roof, basement, wall or hollow bridge beam, especially for hollow beamless roof.
