Prefabricated pieced two-way slab construction method

Abstract

The invention provides a prefabricated pieced two-way slab construction method. The method comprises the following steps: (1) prefabricated slabs are laid; (2) at the pieced places of the prefabricated slabs, soft rubber plates are supported and laid; (3) a reinforcing steel frame is laid on the soft rubber plates; (4) concrete is cast at the pieced places of the prefabricated slabs; (5) maintenance is carried out; (6) the supports are removed; and (7) the soft rubber plates are removed and the prefabricated pieced two-way slabs are obtained. Thus, through the above steps, a prefabricated pieced slab which is formed by piecing the prefabricated slabs and has good two-way stiffness can be obtained, the lower part does not need to adopt a high-energy consumption and high-cost template material such as a bamboo template or a steel template, the cost is reduced, and in addition, according to the prefabricated pieced two-way slab obtained by adopting the above method, as the reinforcing steel frame and cast-in-situ concrete connection are arranged at the pieced places of the prefabricated slabs, a situation in which the middle part is broken does not happen under effects of earthquake disasters, and the safety performance of the building is improved.

Description

technical field [0001] The invention relates to the field of prefabricated buildings, in particular to a construction method for a prefabricated split two-way floor slab. Background technique [0002] In prefabricated buildings, the floor slabs, floor slabs, wall panels and other components are usually prefabricated in the factory, and then the connection nodes between the prefabricated components are poured on site to form an overall structure at the construction site. In order to strengthen the integrity of the connection between the floors, the commonly used method is to laminate the floors. Although the integrity of the laminated floors is better, there are many wet operations on site, the environmental pollution is relatively large, and a large number of formwork and supports are required. Construction less efficient. At present, there are also construction units that use fully prefabricated floor slabs. The general method is to pour concrete between two adjacent prefa...

In order to strengthen the integrity of the connection between the floors, the commonly used method is to laminate the floors. Although the integrity of the laminated floors is better, there are many wet operations on site, the environmental pollution is relatively large, and a large number of formwork and supports are required. Construction less efficient

At present, there are also construction units that use fully prefabricated floor slabs. The general method is to pour concrete between two adjacent prefabricated slabs, and connect the prefabricated slabs into a whole by the concrete. The floor slab with this structure has high construction efficiency and is very convenient for wet work on site. Less, but the integrity is poor, and the connection between the cast-in-place concrete and the prefabricated slab is not firm
