Problems solved by technology

However, after this formwork component is applied to the cast-in-place concrete hollow floor, the formed floor will inevitably be equipped with components such as various lines, and often needs to drill holes on the newly repaired floor, and it is difficult to install. Repair is very troublesome

Abstract

Disclosed is a hollow box for concrete structure, which comprises an upper box board (1) and peripheral formworks (2), characterized in that the hollow box is provided with an overhead member (3) for dangling the lower end of the peripheral framework (2). The invention can be applied to various cast-in-situ reinforced-bar concrete or prestressed reinforced-bar concrete hollow building roofings, house roofings, walls, foundation bedplates and hollow bridges, especially for hollow flat slabs.

Description

(1) Technical field [0001] The invention relates to an open box for a concrete structure. (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, whi...
