Prefabricated bottom plate preparation method, prefabricated bottom plate structure and construction method of prefabricated bottom plate structure

Abstract

The invention discloses a prefabricated bottom plate preparation method, a prefabricated bottom plate structure and a construction method of the prefabricated bottom plate structure. The prefabricated bottom plate preparation method comprises the following steps that a bottom plate mold is assembled, and rib outlet holes do not need to be formed in a side mold of the mold; longitudinal stress steel bars and transverse distribution bars are welded to form a steel bar mesh according to the size of the mold; steel bar trusses are arranged in a segmented mode in the longitudinal bar direction of the steel bar mesh, and the bottoms of the steel bar trusses are bound and fixed to the steel bar mesh; concrete is poured; and when the concrete is close to initial setting, galling treatment is carried out on the surface of the concrete. According to the prefabricated bottom plate preparation method, the prefabricated bottom plate structure prepared through the method can prevent the prefabricated bottom plate structure and beam stirrups from abutting against each other without checking the relative positions of the prefabricated bottom plate outlet bars and the beam stirrups one by one, and standardized design of the mold can be achieved. The invention further aims to provide the construction method.

Description

technical field [0001] The invention relates to the technical field of prefabricated buildings, in particular to a method for preparing a prefabricated floor, a prefabricated floor structure and a construction method thereof. Background technique [0002] At present, the laminated slab floor used in prefabricated buildings is as follows: figure 1 As shown, most of them are reinforced on four sides or double-sided. The main purpose of reinforcing the laminated slab is to connect the exposed reinforcement of the laminated slab to the adjacent laminated slab or to the adjacent beam when pouring the upper concrete. Connection, increasing the stability and integrity of the laminated board installation connection. However, there are many irrationalities in the reinforcement of laminated plates, and the main shortcomings are as follows: [0003] 1. The ribs of the laminated plate cannot be standardized in the mold design, which increases the cost; [0004] 2. For the reinforceme...

AI Technical Summary

Problems solved by technology

[0003] 1. The ribs of the laminated plate cannot be standardized in the mold design, which increases the cost;

[0004] 2. For the reinforcement of the laminated plate, the mold design needs to open reinforcement holes, which is prone to grout leakage and affects the quality of the components;

[0005] 3. For the reinforcement of the laminated slab, it is necessary to consider the interference between the laminated slab and the beam stirrup during installation, which affects the installation efficiency
