Abstract

Disclosed is a hollow member which comprises a hollow form (1) and bottom slab (2), the hollow form (1) and the bottom slab (2) are connected into an integrity, at least two hollow forms (1) on the bottom slab (2) are arranged alternatively, their side surfaces and the structural bottom boards (2) constitute at least one secandary rib molding chamber (3) of cast-in-situ structure, the other outer side surfaces (4) of the hollow form (1) constitute the side casting plates of the structural main ribs or beams or walls, at least one of the corners of the hollow formwork (1) is configured to be a chamfering (5), The invention can be applied to cast-in-situ reinforced concrete or prestressed reinforcement concrete's hollow storied-building roofings, house roofings, walls, foundation bedplates and hollow bridges.

Description

[0001] This application is a divisional application of the invention patent application with the filing date of May 26, 2003, the application number of 03124413.0, and the title of "A Cavity Member". (1) Technical field [0002] The present invention relates to a cavity member. (2) Background technology [0003] At present, most buildings with brick-concrete structure and reinforced concrete structure use prefabricated hollow slabs as floor slabs, which have the advantages of fast construction speed and low cost. However, because there is no firm connection between two adjacent prefabricated hollow slabs, only cement mortar is used to fill the joints, so the integrity is poor, which is not conducive to earthquake resistance, and cracks and water seepage often occur in the gaps. In order to solve the above problems, many buildings adopt the method of cast-in-place concrete floor slabs (solid and hollow). Although the problems of earthquake resistance and cracking have been so...
