Problems solved by technology

However, because there is no reinforced structure in the cavity formwork, the overall strength and rigidity of the cavity components are poor, and the cavity formwork is prone to rupture. After being applied to the hollow floor, it cannot be well Participate in the force and transmission of the hollow floor, therefore, it is urgent to develop a new type of cavity component

Abstract

Disclosed is a hollow member which comprises a hollow form (1) and bottom slab (2), the hollow formwork (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 inner 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, characterized in that the hollow form (1) is provided with at least a reinforcing member (5), the invention can be applied to various cast-in-situ reinforced-bar concrete or prestressed reinforced-bar concrete hollow building roofings, house roofings, foundation slabs, walls or hollow bridges, especially for hollow flat slabs.

Description

[0001] This application is a divisional application of an invention patent application with the filing date of June 2, 2003, the application number of 200610006580.0, 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...
