Problems solved by technology

However, the lower slab of this floor slab is a prefabricated thin slab, and there are splicing joints between them, so the integrity is poor. If the lower slab is a cast-in-place reinforced concrete slab, although the integrity is good and there is no problem of splicing joints, the construction is inconvenient , the cast-in-place concrete is not dense, and problems such as honeycomb pits are prone to occur. At the same time, the cast-in-place concrete ribs formed between the formwork members in this floor slab are all rectangular cast-in-place concrete ribs, and their mechanical performance is not good. Very reasonable, it is often necessary to increase the cross-sectional size of cast-in-place concrete ribs, increase the amount of steel bars and concrete, and increase the cost of the floor. Therefore, it is urgent to develop a new formwork member

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 the described upper plate has a top window for depositing concrete, on the top window a top window cover or a top window plug is set. 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...
