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

[0034] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0035] As shown in the accompanying drawings, the present invention comprises a plurality of prefabricated cavity formworks 1 and a structural base plate 2, at least two prefabricated cavity formworks 1 are arranged alternately on the structural base plate 2, and the alternate cavity formworks 1 and the structure The bottom plate 2 constitutes the structural inner rib cavity 3 for cast-in-place, and the cavity formwork 1 is connected with the structural bottom plate 2 as a whole, and the feature is that the inner rib cavity 3 is provided with a brace 4 to connect the cavity formwork 1. Cavity formwork 1 is an open cavity formwork. As shown in Figure 1, the cavity component includes a prefabricated cavity formwork 1 and a structural bottom plate 2, and the prefabricated cavity formwork 1 is arranged alternately on the structural bottom plate 2, and the a...

Abstract

A hollow component for hollow plate consists of several open hollow mould shells and a substrate. At least two shells are arranged on the substrate and spaced each other to form internal rib cavities for casting in site. Some supporting parts are arranged in the internal rib cavities, so that the hollow component has higher strength and better shockproof performance. It has simple structure, costs low, is manufactured efficiently, and can be used for hollow plate of reinforced concrete cast in site or pre-fabricated reinforced concrete for hollow plate, hollow roof, basement, wall and hollow bridge beam, especially for hollow beamless roof.

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...
