Abstract

A hollow component consists of a substrate and several hollow molded chambers on it uniformly. Two, at least, molded chambers arranged in space. One, at least, inner molding rib chamber formed by sidewall of each chamber and the substrate is cast in site. The outer molding surface of the chamber is formed to be rib, beam or wall cast in site. One chamber, at least, has some holes to be cast into supports in the chamber inside to transfer and bear load so as to improve its mechanical performance. It is available in hollow floors, roofs, foundation substrates, walls and bridge beams of concrete cast in site.

Description

(1) Technical field [0001] The present invention relates to a cavity member. (2) Background technology [0002] 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 solved, a large number of templates are used during construction, which not only increases the cost, but also slows down the construction speed and prolongs the construction period. deadline.
