Cast-in-situ concrete slab

Abstract

Disclosed is a cast-in-situ concrete slab, which comprises a reinforced-bar concrete (1) and shuttering members (2), the shuttering members (2) comprise an upper board (3) and peripheral side panels (4), the upper board (3) and the peripheral side panels (4) encloses an open basin shape component, cast-in-situ reinforced bar concrete ribs (5) formed by the reinforced-bar concrete (1) are disposed between the peripheral side walls (4) of the shuttering members (2), cast-in-situ reinforced bar concrete overlapping layers formed by the reinforced-bar concrete (1) are disposed above the upper board (3) of the shuttering members (2), and are connected to the cast-in-situ reinforced bar concrete ribs (5), the reinforced-bar concrete (1) and the shuttering members (2) are superposed into an integrity, characterized in that a ring tyre bottom rib groove (7) is arranged on the lower opening edge of the peripheral panels (4), the cast-in-situ concrete forms cast-in-situ concrete reinforcement ribs (8) at bottom rib groove (7) position, rims of the cast-in-situ reinforced-bar concrete ribs (5) are formed on the cast-in-situ concrete reinforcement ribs (8), and reversed T ribs are formed on the cast-in-situ reinforced-bar concrete ribs (5). 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 board. (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 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 slabs (hollow, solid). Although the cast-in-place concrete slab solves the problems of earthquake resistance and cracking, a large number of templates are used during construction, which not...

AI Technical Summary

Problems solved by technology

However, the cast-in-place concrete slab is in the evacuated part of the formwork member, the strength and stiffness of the cast-in-place concrete slab are relatively poor, and the ability to withstand concentrated loads is relatively low. Therefore, it is urgent to develop a new type of cast-in-place concrete slab
