Abstract

The invention discloses a prefabricated reinforced concrete shear wall vertical splicing joint structure and a construction method thereof. The prefabricated reinforced concrete shear wall vertical splicing joint structure comprises an upper reinforced concrete shear wall and a lower reinforced concrete shear wall, and an area between the lower end of the upper reinforced concrete shear wall and the upper end of the lower reinforced concrete shear wall is a connecting area. Ultra-high performance concrete is poured in the connecting area to enable the upper reinforced concrete shear wall and the lower reinforced concrete shear wall to be connected as a whole. The prefabricated reinforced concrete shear wall vertical splicing joint structure applies the ultra-high performance concrete between the reinforced concrete shear walls, and fully utilizes the excellent compression resistance and tensile performance of the ultra-high performance concrete, thereby solving the problem of weak connection in joint regions.

Description

technical field [0001] The invention belongs to the technical field of building structures, and in particular relates to a prefabricated assembled reinforced concrete shear wall vertical splicing node structure and a construction method thereof. Background technique [0002] Prefabricated reinforced concrete structure is one of the important directions for the development of building structures in my country. It has the advantages of controllable product quality, green environmental protection and convenient construction. The vertical connection area between prefabricated concrete shear walls is a sensitive part of the prefabricated concrete shear wall structure, and it is also a weak link of the structure. Therefore, the connection method between prefabricated concrete shear walls affects the safety, durability and functionality of the structure. The connection methods of traditional prefabricated concrete shear wall structures mainly include: grouting sleeve connection, r...
