Problems solved by technology

However, during the handling and construction of this kind of cavity components, the structural bottom plate is prone to breakage, so the damage rate of the cavity components 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 cavity member for hollow slabs.

Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0034] As shown in the accompanying drawings, the present invention comprises a plurality of prefabricated openings or closed cavity formworks 1 and a structural bottom plate 2, and at least two prefabricated openings or closed cavity formworks 1 are arranged alternately on the structural bottom plate 2, and the spaces between them are arranged alternately. The cavity formwork 1 and the structural bottom plate 2 form a structural inner rib cavity 3 for cast-in-place, and the cavity formwork 1 and the structural bottom plate 2 are connected as a whole, and the feature is that the inner rib cavity 3 is provided with a brace 4 , there is at least one groove 5 on the prefabricated opening or closed cavity formwork 1, at least two grooves 5 of the adjacent prefabricated opening or closed cavity formwork 1 are on the same straight line, and the grooves 5 on th...

Abstract

A hollow component for hollow plate consists of a substrate and at least two pre-fabricated pre-stressed open or closed mould shells spaced each other on the substrate to form internal rib cavities, where some supporting parts are arranged. Some groove are arranged on the said shells and aligned for casting reinforced concrete strips connected with the said supporting parts. It can be used for hollow plate of reinforced concrete cast in site or pre-fabricated concrete, roof, basement, wall, or hollow bridge beam.

Description

(1) Technical field [0001] The present invention relates to a cavity member for a hollow plate. (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 construc...
