Method for manufacturing pre-fabricated reinforced concrete plate with rib

Abstract

The present invention relates to a fabrication method of a reinforced concrete ribbed precast slab. The fabrication method includes the following steps: (1) preparation of wet concrete material; (2) laying of longitudinal reinforcing steel bars (1) in a base slab; (3) pouring of concrete slurry (3) in a T-shaped template (2); (4) compacting of concrete and scraping of the surface of the flat slab; (5) maintenance. Consequently, when the reinforced concrete ribbed precast slab is fabricated, the concrete slurry is poured into the T-shaped template, so that the T-shaped slab can be casted in one step. Moreover, the longitudinal reinforcing steel bars laid in the base slab can enhance the strength of the precast slab. When the fabrication method is adopted to produce the reinforced concrete ribbed precast slab, the whole process is simple and convenient, the period is short, the template can be easily disassembled or can serve as a permanent template, and therefore the purpose of the present invention is achieved.

Description

(1) Technical field [0001] The invention relates to a method for manufacturing a reinforced concrete ribbed prefabricated panel. (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 ...

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.
