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), the upper box board (1) and the peripheral formworks are split-and-paste prefabricated members, characterized in that the upper box board (1) covers on the peripheral frameworks (2), the upper box board (1) is provided with a concrete casting upper hole (3) or / and a communicating tube hole (4). As a result, the hollow box can be equipped with other members easily. The invention can be applied to various building slabs, house roofings, walls, foundation bedplates and hollow bridges.

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...
