Problems solved by technology
However, after being applied to reinforced concrete hollow slabs, the cast-in-place concrete ribs formed between the cavity members are all rectangular cast-in-place concrete ribs, and their mechanical performance is not very reasonable. It is often necessary to increase the cross-sectional size of the cast-in-place concrete ribs. Increase the amount of steel and concrete, increase the cost of reinforced concrete hollow slab, therefore, it is urgently needed to develop a new type of reinforced concrete hollow slab

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 an upper board (4), peripheral side panels (5), and a lower bottom (6), the upper board (4), the peripheral side panels (5), and the lower bottom (6) enclose a polyhedral hollow member, the invention is characterized in that at least a bottom rib recess (7) is arranged between the side panels (5) and the lower bottom (6), a reinforced structure (8) of the reinforced-bar concrete hollow slab is formed on the recess (7) position of the cast-in-situ concrete, a reversed T-shape rib is formed by the cast-in-situ reinforced bar concrete rib (3) together with the reinforced structure (8) on the corresponding sites, at least one of the side pieces (5) of the hollow member is provided with a transverse groove (7), the cast-in-situ concrete forms a transverse reinforcement structure (8) in the groove (7). The invention can be applied to cast-in-situ reinforced-bar concrete hollow slabs, storied building covers, house roofings, walls, and foundation slabs.
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 slab is a widely used floor structure. The lightweight permanent tire molds filled in it include various hollow tubes and boxes, and the boxes are hollow or solid. For example, the patent No. ZL99249798.1, which the applicant applied for on November 29, 1999, is a utility model patent named "fiber-reinforced thin-walled member for reinforced concrete filling", which discloses a thin-walled formwork member, including an upper plate, The surrounding side walls, the lower bottom, and the upper plate, the surrounding side walls and the lower bottom form a polyhedral cavity. Another example is the patent No. ZL00203695.9 applied by Liang Jun, Shijiazhuang City, Hebei Province on February 23, 2000, and the name is called "combined concrete hidden rib floor cover plate" utility model patent, which disclos...
