Problems solved by technology

However, during the handling and construction of such cavity components, the structural bottom plate is prone to breakage, so the damage rate of the cavity components is high, and the handling and construction are inconvenient, which increases the construction cost.

Embodiment Construction

[0028]The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] As shown in the accompanying drawings, the present invention includes a concrete bottom plate 1 and filling bodies 2 on the concrete bottom plate 1. The filling bodies 2 are alternately arranged on the concrete bottom plate 1 and connected with it to form an integral force-bearing member. The rib cavity 3 is parallel or orthogonal, and it is characterized in that there is a stretcher 4 in the inner rib cavity 3, and at least one longitudinal upper steel bar 5 passes through at least one inner rib cavity 3 and at least two The filling body 2, the brace 4 or / and the longitudinally long upper steel bar 5 and the filling body 2 jointly form a conjoined cooperative upper stress-bearing member, and the concrete bottom plate 1 and the filling body 2 are the lower cooperative stress-bearing members. In each drawing, 1 is the concrete bottom plate, 2 is th...

Abstract

A hollow component used as filler of a hollow plate consists of a substrate, filling bodies on the substrate, spaced each other and integrated with it to form a whole body. The internal mould cavities between the filling bodies are parallel or perpendicular. Some supporting parts are arranged in the internal cavities. At least one upper steel bar goes through at least one internal mould cavity and at least two filling bodies. The supporting parts and filling bodies and upper steel bar form upper bearing unit commonly, so that the hollow component has high strength, is not easily broken, and can be used for hollow board, roof, foundation substrate, wall and hollow bridge beam, especially the hollow bridge beam.

Description

(1) Technical field [0001] The invention relates to a cavity component for filling concrete hollow slabs. (2) Background technology [0002] At present, most buildings with brick-concrete structure and reinforced concrete structure use prefabricated hollow slabs as floor slabs, which have 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 t...
