Abstract

The present invention relates to a hollow cavity form member for pouring concrete. It includes upper plate and peripheral side wall. Said upper plate and peripheral side wall can be connected together and formed into the hollow form with opening. It is characterized by that said hollow form is made up by using at least two prefabricated plates through a certain match-combination process. Said two prefabricated plates can be connected together by means of connecting component, and can be formed into open hollow cavity or closed hollow cavity, the end face of every prefabricated plate is equipped with projected wedge or / and recessed groove. Said hollow cavity form member is applicable to the construction of cast-in-situ reinforced concrete or prestressed reinforced concrete hollow floor, roof, wall body, foundation baseplate and open-web bridge, etc.

Description

[0001] This application is a divisional application of an invention patent application with a filing date of December 9, 2003, an application number of 200310121937.6, and a title of “A Cavity Formwork Member for Concrete Filling”. (1) Technical field [0002] The invention relates to a cavity formwork component for concrete filling. (2) Background technology [0003] At present, most of the buildings with brick-concrete structure and frame structure use prefabricated hollow-core slabs as floor slabs. This kind of floor slab has the advantages of fast construction speed and low cost, but because there is no firm connection between two adjacent prefabricated hollow-core slabs , Only cement mortar is used to fill the gaps, so not only the integrity is poor, which is not conducive to earthquake resistance, but also cracks and water seepage often occur in the gaps, causing great inconvenience and psychological pressure to the residents. In order to solve the above problems, many...
