Problems solved by technology

However, during the handling and construction of the cavity components in this concrete hollow slab, the structural bottom plate is prone to breakage, the damage rate is large, the handling and construction are inconvenient, and the construction cost is increased. At the same time, its production is more troublesome and costly. Therefore, it is urgently needed to develop a new type of concrete hollow slab

Embodiment Construction

[0051] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0052] As shown in the accompanying drawings, the present invention includes cast-in-place reinforced concrete 21 and cavity members 22 for filling. The cavity members 22 for filling are arranged alternately and wrapped in the cast-in-place reinforced concrete 21. There are cast-in-place concrete ribs 23 between them, and the cavity member 22 for filling includes a plurality of prefabricated open or closed cavity formwork 1, a structural bottom plate 2, and there are at least two prefabricated open or closed cavity formwork shells on the structural bottom plate 2 1 Alternately arranged, the alternate cavity formwork 1 and the structural bottom plate 2 constitute the inner rib cavity 3 for cast-in-place structure, the cavity formwork 1 and the structural bottom plate 2 are connected as a whole, and the inner rib cavity 3 has cast-in-place reinforced concr...

Abstract

A lightweight reinforced concrete comprises concrete cast in site, hollow components as fillers spaced each other and contained in the former, and some internal ribs are cast in site. Some hollow mould shells are arranged on the substrate to form internal mould cavities, which are equipped with supporting parts in them and grooves on the said shells. The grooves on the adjacent pre-fabricated open or closed mould shells, at least two of them, are aligned and filled with reinforced concrete connected with the supporting parts in the internal mould cavities. The concrete can be used as roof.

Description

(1) Technical field [0001] The invention relates to a concrete hollow slab. (2) Background technology [0002] At present, most of the buildings with brick-concrete structure and reinforced concrete structure use prefabricated hollow slabs as floor slabs. This floor slab has the advantages of fast construction speed and low cost. However, because there is no firm connection between two adjacent prefabricated hollow slabs, only cement mortar is used to fill the joints, so the integrity is poor, which is not conducive to earthquake resistance, and cracks and water seepage often occur in the gaps. In order to solve the above problems, many buildings adopt the method of cast-in-place concrete floor slabs (solid and hollow). Although the problems of earthquake resistance and cracking have been solved, a large number of templates are used during construction, which not only increases the cost, but also slows down the construction speed and prolongs the construction period. deadli...
