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), 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 two of the basin form components are spaced arranged, the opposed faces of which form a die cavity in the cast-in-situ concrete inner rib (7), which is provided with at least one spacing tension member (8) for connecting the two basin shape components, the cast-in-situ reinforced-bar concrete (1) forms a cast-in-situ reinforced bar concrete inner rib (7) inside the inner rib molding chamber (7), The invention can be applied to roofs, foundation floors and walls.

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 concrete slab solves the problems of earthquake resistance and cracking, a large number of templates are used during construction, which not only increa...

AI Technical Summary

Problems solved by technology

However, during the construction of this kind of cast-in-place concrete slab, the formwork components need to be laid out individually for construction, and it is inconvenient to locate each other, and the formwork components are prone to misalignment, which affects the construction quality of the cast-in-place concrete slab and also affects the construction efficiency. A new type of cast-in-place concrete slab is urgently needed
