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

[0047] The present invention will be further described below in conjunction with the drawings and embodiments.

[0048] The present invention, as shown in the drawings, includes a reinforced concrete 1 and a formwork member 2. The formwork member 2 is wrapped in the reinforced concrete 1, and the formwork members 2 are arranged alternately, with cast-in-situ reinforced concrete ribs 3 between them. It is the cast-in-place reinforced concrete upper plate 4, and the lower is the cast-in-place reinforced concrete lower plate 5. The formwork member 2 includes an upper plate 6, a surrounding side wall 7, and an open basin-shaped member surrounded by the upper plate 6, and the surrounding side wall 7 It is characterized in that at least one skylight 8 is opened on the upper plate 6 of the pot-shaped member, the lower wall of the surrounding side wall 7 has at least one overhead foot 16 of the overhead side wall, and the skylight 8 has a movable cover 15. In the drawings, 1 is reinforced...

Abstract

Disclosed is a cast-in-situ 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), wherein 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 at a central portion. 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 buildings with brick-concrete structure and frame structure use prefabricated hollow 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 slabs , Only use cement mortar to fill the gaps, so not only the integrity is poor and it is not conducive to earthquake resistance, but also cracks and water seepage often occur in the gaps, 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. This not only incr...
