Abstract
A reinforced concrete comprises concrete cast in site, hollow components as fillers spaced each other and contained in the former, and some ribs are cast in site between the said fillers. Some tunnel over-linked plates are arranged downward and spaced each other, between which some lateral mould cavities are formed and filled with concrete cast in site to form internal ribs. Some longitudinal ribs on a substrate have holes to go through the said lateral mould cavities, where some concrete is cast in site to form ribs and to go through the said holes. The concrete can be used as hollow roof, basement, wall or hollow bridge beam, especially as hollow beamless roof.
Description
(1) technical field
