Problems solved by technology
This kind of hollow slab includes reinforced concrete and hollow formwork, and the hollow formwork is wrapped in reinforced concrete. During construction, the hollow formwork needs to be laid out individually, which is inconvenient to locate each other and easily misplaced, which affects the construction quality of the hollow slab. At the same time, it also affects the construction efficiency of the hollow slab. Therefore, it is urgently needed to develop a new type of concrete hollow slab.

Embodiment Construction
[0097] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0098] As shown in the accompanying drawings, the present invention includes reinforced concrete 1 and fasting formwork 2, and the fasting formwork 2 is wrapped in the reinforced concrete 1. It is characterized in that at least two fasting formworks 2 are arranged alternately. The cast-in-place concrete inner rib mold cavity 3 is formed between the opposite surfaces, and there is at least one spacer brace 4 connecting the empty stomach formwork 2 into an assembly in the inner rib mold cavity 3, and the cast-in-place reinforced concrete 1 is in the inner rib mold cavity 3 The concealed ribs 5 of cast-in-situ reinforced concrete are formed, and the upper surface or / and lower surface of the hollow formwork 2 are exposed to pour concrete. figure 1 It is a structural schematic diagram of Embodiment 1 of the present invention. figure 1 Among them, 1 is reinf...

Disclosed is a concrete hollow slab which comprises a reinforced-bar concrete (1) and hollow formworks (2) enclosed in the reinforced-bar concrete (1), characterized in that at least two of formworks (2) are arranged alternatively, the opposed faces of the two hollow formworks (2) constitute a cast-in-situ in-concrete rib moulding chamber (3), the inner rib molding chamber (3) is provided with at least one spacing tension member (4) for connecting the two hollow framework (2) into assembly, the cast-in-situ reinforced-bar concrete forms a cast-in-situ reinforced bar concrete hidden dens rib (5) inside the inner rib molding chamber (3), cast-in-situ concrete is exposed from the upper surface or / and lower surface of the hollow formworks (2). The invention can be applied to various cast-in-situ reinforced-bar concrete or prestressed reinforced-bar concrete hollow building roofings, house roofings, foundation slabs, walls, and hollow bridges, especially for hollow flat slabs.
Description
[0001] This application is a divisional application of the invention patent application with the filing date of May 20, 2003, the application number of 200510129835.8, and the title of "a concrete hollow slab". (1) Technical field [0002] The invention relates to a concrete hollow slab. (2) Background technology [0003] At present, the cast-in-place reinforced concrete hollow slab is a widely used floor structure, which has the advantages of fast construction speed, small structural height, flexible division of indoor areas, and no need for ceiling decoration. The lightweight permanent tire molds filled with it are available in various hollow tubes and boxes, hollow or solid. For example, the patent No. ZL99232921.3, which the applicant applied for on March 10, 1999, is a utility model patent named "thin-walled tube for filling cast-in-place reinforced concrete", which consists of a hard thin-walled tube and two plugs. Used in hollow slabs as a lightweight permanent tire ...
