Problems solved by technology

However, the lower slab of this floor slab is a prefabricated thin slab, and there are joints between them, so the integrity is poor. If the lower slab is a cast-in-place reinforced concrete slab, although the integrity is good and there is no problem of joints, the construc

Embodiment Construction

[0093] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0094] 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 the upper plate 6 of the basin-shaped member is provided with a skylight 8 for carrying out concrete construction work in the lower chamber of the upper plate 6, and there is at least one overhead support member 9 for elevating the surrounding side walls 7, and the skyli...

Abstract

The present invention relates to a cast-in-situ concrete hollow plate. It includes reinforced concrete and form members. The form members are contained in the reinforced concrete, and are alternatively arranged, between them a cast-in-place reinforced concrete rib is set, its upper portion is cast-in-place reinforced concrete upper plate and its lower portion is cast-in-place reinforced concrete lower plate, the form member includes upper plate and peripheral side wall, said upper plate and peripheral side wall can be connected together and formed into an open basin-shaped member. It is characterized by that on the upper plate of the described basin-shaped member a top window for making concrete construction operation in the lower cavity of said upper plate is set, and said top window is equipped with a top window cover. Said form member can be used for in-situ casting reinforced concrete or prestressed reinforced concrete hollow floor, roof, wall body, foundation bedplate and open-web bridge, etc.

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...
