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 a vertical groove is arranged on the peripheral panel panels, thus, when the shuttering member is applied to the cast-in-situs of concrete building covers, a reinforced rib can be formed by cast-in-situs concrete between the shuttering members, thus bettering earthquake resistant behavior of the building cover, the building covers have large strength and stiffness, thus they have strong capacity for bearing actions of concentrated load, when the shuttering member are arranged closely in the building covers, vertical piers or columns can be formed in the vertical groove, thus further reducing the consumption of reinforcing steel and concrete, correspondingly the building cover becomes shearing force pier type one, thus further substantially improving the building cover mechanic performance. 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, during the construction of this floor slab, the strength and stiffness of the cast-in-place concrete hidden ribs between the formwork members are relatively low, and the ability to withstand concentrated loads is weak, and it is impossible to form a shear pier floor
