Concrete room cell with monolithic end walls

摘要

The end walls (14) are cast out of concrete on a base plate (12) and a joist (16) is cast between the end walls along the longitudinal edges (13) of the base plate. The height (h1) of the joist is at least twice the thickness (h2) of the base plate. Anchors for a transport cradle or other support device are inserted in the joists and the position of these determines the apertures in the roof panel (20). A pre-stressed concrete hollow plate with slack marginal reinforcement can be used as the roof plate. Installation pipes can be formed between the joists of the base plate and the wall projections of the end walls.
