Problems solved by technology

However, the lower floor of this cast-in-place concrete hollow slab is a prefabricated thin plate, and there are joints between them, so the integrity is poor. The construction is inconvenient, the cast-in-place concrete is not dense, and problems such as honeycomb pits are prone to occur. Therefore, it is urgently needed to develop a new type of cast-in-place concrete hollow slab.

Embodiment Construction

[0103] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0104] As shown in the accompanying drawings, the present invention includes reinforced concrete 1 and formwork components 2, the formwork components 2 are wrapped in the reinforced concrete 1, the formwork components 2 are arranged alternately, and there are cast-in-situ reinforced concrete ribs 3 between them. It is an upper plate 4 of cast-in-place reinforced concrete, under which is a lower plate 5 of cast-in-place reinforced concrete, and the formwork member 2 includes an upper plate 6 and surrounding side walls 7, which form an open basin-shaped member , It is characterized in that at least one skylight 8 for construction work is opened on the upper plate 6 of the basin-shaped member, and a skylight cover 13 is arranged on the skylight. In the drawings, 1 is reinforced concrete, 2 is formwork components, 3 is cast-in-place reinforced concrete ribs...

Abstract

The in-situ cast hollow reinforced concrete slab includes reinforced concrete and shuttering members. The shuttering members are arranged in certain intervals with in-situ cast reinforced concrete in between and sandwiched between the upper in-situ cast reinforced concrete plate and the lower in-situ cast reinforced concrete plate. Each of the shuttering members is one open-mouthed basin shaped member comprising one upper plate and side plates, and features that the basin shaped member has one skylight with one cover in the upper plate. The present invention is suitable for in-situ cast or pre-stressed reinforced concrete hollow floor slab, roof, wall, foundation slab and hollow bridge, especially hollow flat floor slab.

Description

(1) Technical field [0001] The invention relates to a cast-in-place concrete hollow slab. (2) Background technology [0002] At present, most buildings with brick-concrete structure and frame structure use prefabricated hollow slabs as cast-in-place concrete hollow slabs. This kind of cast-in-place concrete hollow slabs has the advantages of fast construction speed and low cost. There is no firm connection between the boards, and only cement mortar is used to fill the gaps. Therefore, not only the integrity is poor, which is not conducive to earthquake resistance, but also cracks in the gaps 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 con...
