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.
