Fabricated shear wall cast-in-site segment small-spliced-mould casting construction system

Abstract

The invention belongs to the technical field of building construction, and particularly relates to a fabricated shear wall cast-in-site segment small-spliced-mould casting construction system which comprises a prefabricated wall A, a prefabricated wall B, mould plates, square pillars, straight back edges, L-shaped back edges and split screw rods. The prefabricated wall A and the prefabricated wallB are perpendicularly arranged at an interval; the mould plates fit to the inner sides and the outer sides of the prefabricated wall A and the prefabricated wall B; and the end surfaces of the prefabricated wall A and the prefabricated wall B and the mould plates jointly enclose to form an L-shaped casting cavity. According to the fabricated shear wall cast-in-site segment small-spliced-mould casting construction system provided by the invention, through customizing a mould plate reinforcement system, the problems of grout leakage, sagging and poor effect easily happened during the assemblingof conventional fabricated frame structure beams and columns are solved, a forming effect can be effectively ensured, the construction quality is improved, and the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a construction system for small joint formwork pouring of a prefabricated shear wall cast-in-place section. Background technique [0002] The prefabricated shear wall structure is an integral structure formed by prefabricated components through reliable connection methods and on-site post-cast concrete and cement-based grouting materials. Reliable connection nodes are the key to ensuring structural integrity and earthquake resistance. If the construction quality of the connecting nodes cannot be guaranteed, it will easily lead to the failure of the connecting nodes or even cause the overall damage of the structure. There are two types of vertical connection methods for prefabricated shear wall structures: dry connection and wet connection. At present, the most widely used method in China is wet connection. Wet connection mainly includes cast-in-place b...

AI Technical Summary

Problems solved by technology

If the formwork system at the cast-in-place node of the prefabricated shear wall structure is not reinforced enough, it is easy to cause concrete to protrude from the surface of the prefabricated part and leak grout, resulting in poor appearance of the concrete cast-in-place, reducing construction quality and assembly efficiency, etc.
