Reinforced bar concrete hollow slab

Abstract

Disclosed is a reinforced-bar concrete hollow slab, which comprises a reinforced-bar concrete (1) and hollow members (2), the hollow members (2) are enclosed in the reinforced-bar concrete (1), the hollow members (2) are arranged alternatively, and cast-in-situ reinforced-bar concrete rib (3) is arranged between them, the hollow members (2) comprise a hollow formwork (4) characterized in that the hollow members (2) also comprise a spaced drawing member (5), at least two hollow formworks (4) are arranged alternatively, thus forming a cast-in-situ concrete inner rib molding chamber (6), the inner rib moulding chamber (6) is provided with at least one spaced tension member (5) for connecting the opposite or adjacent hollow formworks (4) into an integrity, the cast-in-situ reinforced-bar concrete forms a cast-in-situ reinforced bar concrete inner rib (7) inside the inner rib molding chamber (6), and is connected to the cast-in-situ reinforced-bar concrete rib (3), the spaced tension member (5) is a telescopic one. The invention can be applied to various cast-in-situ reinforced-bar concrete or prestressed reinforced-bar concrete hollow slabs, storied building covers, house roofings, foundation slabs, walls and hollow bridges.

Description

(1) Technical field [0001] The invention relates to a reinforced concrete hollow slab. (2) Background technology [0002] At present, the cast-in-place reinforced concrete hollow floor 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. It is used as a lightweight permanent tire mold in hollow-core slabs. Another example is the application number 99115666.8 filed by the applicant on November 29, 1999, and the name is "fiber-reinforced thin-walled box for filling cast-in-place reinforce...

AI Technical Summary

Problems solved by technology

However, when this kind of thin-walled box is used as a hollow formwork construction, it needs to be constructed individually, and it is inconvenient to locate each other, and it is prone to misalignment, which affects the construction quality of the hollow floor and also affects the construction efficiency. Therefore, a new type of Reinforced concrete hollow slabs are in urgent need
