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 a transverse arced corner is arranged in the cavity of the basin form component, thus, when the shuttering member is applied to the cast-in-situs of concrete building covers, a cast-in-situs reinforced concrete rib can be formed at the arced corner position, thus the stress concentration on the corner position of the cast-in-situs concrete upper board and the hiden concrete rib in the building cover can be eliminated effectively, the production of cracks can be prevented, the earthquake resistant behavior of the building cover can be improved. 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, especially for hollow flat slabs.

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 lateral corners of the formwork members in this floor slab, such as the intersection of the cast-in-place concrete hidden rib and the cast-in-place concrete upper slab, the stress on the floor is more complicated, the stress is more concentrated, and cracks are easy to occur, and even cracking damage, therefore, the development of a new formwork member has been urgently needed
