SLAB CONSTRUCTION

摘要

The invention concerns a slab construction in which concrete is placed in situ on permanent formwork. The formwork includes spaced apart, parallel, channel structures (14) and formers (26) which are located between and are supported by the channel structures. Each channel structure has two or more channel-section formations located side-by-side. The concrete fills the channel structures to form spaced apart beam formations and covers the formers to form slab formations shallower than the beam formations.
