Sets of building elements for civil engineering units - are formed from reinforced concrete members based on plastic tubes and shells

摘要

Building component sets for assembly and use in civil engineering, mining, bridges, walls, beams, etc., are produced from rectangular bodies (1,6,7) together with hollow chambered details (3,8,12), laying the hollow details on to a concrete base member - if the hollow details are not sufficiently strong in themselves, they may be filled with reinforcements (5,9), and the enclosing concrete (7) is then poured on to form the shells and reinforcing members, for the products to be used positioned horizontally or vertically, as walls, covers supports, and ducts.
