Abstract

The invention relates to a cast-in-place concrete cored slab which comprises reinforced concrete (1) and evacuated mould shell components (2), wherein the evacuated mould shell components (2) are wrapped into the reinforced concrete (1), cast-in-place concrete ribs (3) are arranged among the evacuated mould shell components (2), and the evacuated mould shell components (2) comprise an upper slab (4), a surrounding side wall (5) and a lower slab (6), and the upper slab (4), the surrounding side wall (5) and the lower slab (6) are enclosed to form the closed evacuated mould shell components. The cast-in-place concrete core slab is characterized in that the upper slab, the surrounding side wall (5) and the lower slab (6) of the closed evacuated mould shell components consist of components (7), the components include at least one precast slab (8) and at least one cast-in-place slab (9) cementing the precast slab (8), the upper surface of the upper slab (4) is lower than that of a visible beam (32) or concealed beam (31), and/or the lower surface of the lower slab (6) is higher than that of the concealed beam (31) or visible beam (32), therefore, the invention is suitable to cored floor systems, roofs, wall bodies, foundation slabs and open bridge beams of cast-in-place reinforced concrete or prestressed reinforced concrete, and is especially suitable to the cored flat slab floor.

Description

[0001] This application is a divisional application of an invention patent application with an application date of June 6, 2005, an application number of 200510074455.9, and a title of "a cast-in-place concrete hollow slab". (1) Technical field [0002] The invention relates to a cast-in-place concrete hollow slab. (2) Background technology [0003] 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 ado...
