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 projected edge is arranged on the peripheral panel panels, at least one of the peripheral side panel and the projected edge is provided with a reinforcement member, thus, when the shuttering member is applied to the cast-in-situs of concrete building covers, it has the advantages of reduced weight, lowered cost, high intensity and stiffness, easy manufacture, low cost. 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 kind of floor slab, it is still necessary to use prefabricated thin slabs as formwork, the weight of the floor is still relatively heavy, and the cost is still high; moreover, the wall thickness of the formwork components is relatively thin, which is easy to be damaged during transportation and construction , especially when hit or collided by various heavy objects and falling objects, due to insufficient strength and poor impact resistance, damaged holes often appear, resulting in damage to the formwork wall, which brings inconvenience to construction, increases costs, and shortens the construction period. affected
