A shuttering member

Abstract

Disclosed is a shuttering member, which comprises an upper board, peripheral side panels, the upper board and the peripheral side panels encloses an open basin shape component, characterized in that at least one of the vertical corner positions of at least one peripheral side panels employs a vertical internal corner, thus, when the shuttering member is applied to the cast-in-situs of concrete hollow building covers, a reinforced rib for cast-in-situs concrete hidden rib can be formed at each internal corner positions, therefore effectively eliminating the stress concentration phenomenon on the building cover, the production of cracks can be prevented, concentrated heavy load can be beard. If the shuttering members are closely spaced, the cast-in-situs concrete can form the shearing piers or columns of the building cover at the vertical internal corner position, thus greatly reducing the consumption of reinforcing steel, the shuttering member also has t he advantages of reducing building roof weight, improving earthquake resistant behavior, bettering earthquake resistant behavior of the building cover. The shuttering members are adapted for the application of hollow building cover, room cover, wall, foundation slab and laced beam bridges of the cast-in-situs reinforcing steel concrete or prestressed reinforcement concrete.

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...

AI Technical Summary

Problems solved by technology

However, at the vertical corners of the formwork components in this floor slab, the stress of the floor is more complicated, the stress is more concentrated, and cracks are easy to occur, or even cracked and damaged.
