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

[0102] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0103] 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 concrete construction in the lower chamber of the upper plate 6, and the surrounding side walls 7 have overhead feet 16 for connecting the side walls 7 or connecting the side walls The lower ...

Abstract

Disclosed is a cast-in-situs concrete hollow slab, which comprises a reinforced-bar concrete (1) and shuttering members (2), the shuttering member (2) is enclosed in the reinforced-bar concrete (1), the shuttering members (2) are arranged alternatively, a cast-in-situ reinforced-bar concrete rib (3) is arranged between them, and a cast-in-situ reinforced concrete upper slab (4) is arranged above, a cast-in-situ reinforced concrete upper slab (5) is arranged below, the shuttering members (2) comprise an upper board (6) and peripheral side panels (7), the upper board (6), and the peripheral side panels (7) encloses an open basin shape component, characterized in that an upper board dormer window (8) is arranged on the upper board (6) of the basin form component. The invention can be applied to cast-in-situ reinforced concrete or prestressed reinforcement concrete's hollow storied-building roofings, house roofings, walls, foundation bedplates and hollow bridges, especially for hollow flat slabs.

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...
