In-situ concrete plate

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 is 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 at least one of the upper board (3) and the peripheral panels (4) is provided with a sheet of overlapping layer (7) in integrity with the substrate. The invention can be applied to various cast-in-situ reinforced concrete or prestressed reinforcement concrete's storied-building roofings, house roofings, walls, foundation bedplates and bridges, especially for hollow flat slabs or dense rib 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, 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 floor slab solves the problems of earthquake resistance and cracking, a large number of formwork is used during construction, which not only increases t...

AI Technical Summary

Problems solved by technology

However, when the formwork components used in this type of cast-in-place concrete board are produced, it is inconvenient to make, the production efficiency is low, it is not convenient for assembly line production, the cost is high, and the construction cost of the corresponding cast-in-place concrete board is high. Therefore, a new type of cast-in-place concrete board is developed. Cast-in-place concrete slabs are urgently needed
