Abstract

A hollow plate of cast-in-situ concrete is composed of reinforced concrete(1), mold-shell member(2), cast-in-situ reinforced concrete rib(3), cast-in-situ reinforced concrete top plate(4), cast-in-situ reinforced concrete bottom plate(5), top plate(6), peripheral side walls(7), scuttle(10), and blind flange(9). Said mold shell member is arranged in said reinforced concrete, which is set spaced between said cast-in-situ reinforced concrete ribs(3) with cast-in-situ reinforced concrete top plate(4) and cast-in-situ reinforced concrete bottom plate(5), top plate(6) and peripheral side walls(7) are enclosed into an open basin-shaped member, whose top plate(6) is arranged with said scuttle, said blind flange(9) is matched with said scuttle, at least one supporting rod(38) is connected with said blind flange(9). It can be used for various hollow and beamless building roofs of cast-in-situ reinforced concrete or pre-stressed reinforced concrete, basic baseboard, wall and bridges.

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...

Embodiment Construction

[0159] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0160] 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 to form an open pot-shaped member, which is characterized in that the pot-shaped The upper plate 6 of the member is provided with a skylight 10 for carrying out concrete construction in the lower chamber of the upper plate 6 , the skylight 10 is equipped with a cover plate 9 , and at least one support rod 38 is connected with the cover pla...
