Problems solved by technology

However, during the handling and construction of the cavity components used in this hollow slab, the structural bottom plate is prone to breakage, so the damage rate of the cavity components is high, and the transportation and construction are inconvenient, which increases the construction cost of the hollow slab

Embodiment Construction

[0063] The present invention will be further described below in conjunction with drawings and embodiments.

[0064] As shown in the accompanying drawings, the present invention includes a cavity member 4 formed by connecting reinforced concrete 1, a cavity formwork 2 and a structural bottom plate 3. The cavity component 4 is wrapped in the reinforced concrete 1, and there are at least 2 The cavity formwork shells 2 are arranged alternately, and their side surfaces and the structural bottom plate 3 form at least one cast-in-place structural secondary rib cavity 5, and the cast-in-place reinforced concrete forms a cast-in-situ reinforced concrete hidden rib 6 in the cast-in-situ structural secondary rib cavity 5, It is characterized in that at least one stretcher 7 is arranged in the secondary rib cavity 4 of the adjacent cavity formwork 2, which connects the adjacent hollow formwork 1 to each other and wraps it in the cast-in-place reinforced concrete hidden rib 6 Among them, t...

Abstract

The hollow reinforced concrete slab includes at least two hollow members comprising reinforced concrete plate, hollow shutterings and structural bottom plate and arranged separately, at least one in-situ cast structural secondary rib mold cavity constituted with the side walls of the hollow members and the structural bottom plate, and hidden in-situ cast rib formed with the in-situ cast reinforced concrete in the in-situ cast structural secondary rib mold cavity. The present invention features that the secondary rib mold cavity has at least one staying part to connect and support the adjacent hollow shutterings and coated inside the hidden in-situ cast rib, and that two or more hollow members are arranged in the some longitudinal axis. The present invention is suitable for use in in-situ cast or pre-stressed reinforced concrete hollow floor slab, roof, base slab, wall and hollow bridge.

Description

[0001] This application is a divisional application of an invention patent application with an application date of May 20, 2003, an application number of 03118392.1, and a title of "a reinforced concrete hollow slab". (1) Technical field [0002] The invention relates to a reinforced concrete hollow slab. (2) Background technology [0003] 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 resistan...
