Prefabricated plate for steel concrete with rib

Abstract

A prefabricated reinforced concrete slab with rib is composed of a long reinforced concrete slab as baseplate and a longitudinal reinforced concrete rib, and features that said baseplate has at least one supporting part on its top surface, whose top surface is leveled with the top surface of said longitudinal rid for overlapping said slabs. It can be used for floor, roof, wall, foundation and bridge.

Description

(1) Technical field [0001] The invention relates to a reinforced concrete prefabricated panel with ribs. (2) Background technology [0002] At present, the reinforced concrete floor slabs used in China include cast-in-place floor slabs and prefabricated floor slabs. The cast-in-place floor slabs have good integrity, but they need to be molded on site, and then concrete is poured. The construction period is difficult, the loss of the formwork is large, and the cost is high. formwork, short construction period and low cost, but the prefabricated components are self-heavy, difficult to hoist, cracks are prone to occur at the splicing parts of the components, and the integrity is poor, such as the patent No. ZL0322765. A reinforced concrete prefabricated component. The prefabricated component is composed of slabs and ribs, and the ribs have holes for passing steel bars. The thickness of the slab is large, which greatly reduces the effective height of the steel bars placed in the...

Problems solved by technology

[0002] At present, the reinforced concrete floor slabs used in China include cast-in-place floor slabs and prefabricated floor slabs. The difficulty is high, the loss of the formwork is large, and the cost is high. The prefabricated floor does not require on-site formwork, the construction period is short, and the cost is low. However, the prefabricated components are heavy and difficult to hoist. Cracks are prone to occur at the splicing parts of the components, and the integrity is poor. For example, the patent number is ZL0322765. 2. The patent titled a reinforced concrete assembled floor slab discloses a reinforced concrete prefabricated component. The prefabricated component is composed of plates and ribs, and the ribs have holes for piercing steel bars. The effective height of the steel bars in the pouring concrete is greatly reduced, which affects the two-way force balance of the floor slab, and it is difficult to form an equivalent two-way slab, etc.
