Hollow component

Abstract

A cavity component includes cavity die shell and base plate. It is featured as connecting said shell with base plate to form an integral unit, arranging at least two said shells on base plate alternatively, using cavity die shell side surface and base plate to form internal-rib die cavity with at least one cast-in-place structure and using the other external side surface of cavity die shell to form external-rib side template of cast-in-place structure, setting convex die block on side template of cavity die shell for decreasing use amount of concrete and projecting convex die block on opposite side template at the same opposite axle.

Description

[0001] This application is a divisional application of the invention patent application with the filing date of June 2, 2003, the application number of 03137263.5, 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...

AI Technical Summary

Problems solved by technology

However, after this cavity component is applied to the hollow floor, the concrete consumption is still relatively large due to the large number of ribs. Therefore, it is urgently needed to develop a new type of cavity component.
