Abstract

The present invention relates to a kind of form member. It includes upper plate and peripheric side wall. Said upper plate and peripheric side wall can be combined together and formed into an open basin-shaped member. It is characterized by that on the upper plate a top window is cut, said top window can be used for making concrete construction operation in the lower cavity of said upper plate, in the top window position is set a movable window-contracting component capable of contracting window size, so that said form member can be used for in-situ casting reinforced concrete or prestressed reinforced concrete hollow floor, roof, wall body, foundation bedplate and open-web bridge, etc.

Description

(1) Technical field

[0001] The present invention relates to a formwork member. (2) Background technology

[0002] 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, causing great inconvenience and psychological pressure to the residents. In order to solve the above problems, many buildings have adopted the method of cast-in-place concrete floor slabs (hollow, solid). Although the cast-in-place concrete floor slab solves the problems of earthquake resistance and cracking, a large number of templates are used during construction, which not only...
