Cast-in-situ concrete hollow slab

Abstract

A cast-in-situ concrete hollow plate comprises reinforced concretes (1) and opening boxes (2), the opening boxes (2) are packed in the reinforced concrete (1) and are separated-arranged, the cast-in-situ reinforced concrete ribs (3) are arranged between one another, the cast-in-situ reinforced concrete upper plate (4) is arranged thereon and the cast-in-situ reinforced concrete lower plate (5) is arranged thereunder, the upper box board (6) and the surrounding formwork (7) surrounds the opening box (2), and the invention is characterized in that the upper box plate (6) and the surrounding formwork (7) are assembled prefabricated pieces after separation, and the upper box plate (6) covers the surrounding formwork (7). In this way the upper box plate and the surrounding formwork are assembled after separation, and the upper box plate covers the surrounding formwork, the detaching and installing are facilitated, the component can be leaded to detachedly conveyed and the conveying is convenient and simple, the dilapidation rate of the component in the conveying process can be reduced, the opening box has the characters of simple structure, high strength, deformation resistance, excellent vibration resisting property, easy manufacturing, high production efficiency, low cost and the like, and the hollow plate is suitable for various building roofs, building covers, walls, base plates and hollow bridges.

Description

(1) Technical field [0001] The invention relates to a cast-in-place concrete hollow slab. (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...

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
