Assembly connection structure and assembly connection construction method of fabricated shear wall structure

Abstract

The invention relates to an assembly connection structure of a fabricated shear wall structure. The structure comprises shear walls; section steel keels are respectively pre-buried at the connecting parts of the left and right shear walls to be connected horizontally; the section steel keels of the two shear walls are connected by means of damping devices; a bottom connection steel mold and a topconnection steel mold are respectively pre-embedded at the connecting parts of the upper and lower layer shear walls to be connected vertically; a hollow grouting filling area is formed between the bottom connection steel mold and the top connection steel mold; by grouting in the grouting filling area, the connection between the bottom connection steel mold and the top connection steel mold is realized. The steel molds are locally pre-embedded so as to realize the vertical connection of the shear walls, so that the alignment difficulty of a reinforcing steel bar and a sleeve during on-site hoisting of a prefabricated wall is greatly reduced, the construction quality is effectively guaranteed, and the reliability of the connection position is improved; a section steel keel structure is adopted by the horizontal connection of the shear walls, so that additional connecting ribs at connecting parts are omitted, the field installation difficulty is effectively reduced, and the constructionefficiency is increased.

Description

technical field [0001] The invention belongs to the technical field of assembled structures, and in particular relates to an assembled connection structure of an assembled shear wall structure and a construction method thereof. Background technique [0002] The prefabricated structure requires its components to be prefabricated in the factory, which reduces the wet work, dust and noise pollution on the construction site, improves the manufacturing accuracy of the components, shortens the construction period to a certain extent, and reduces the use of labor. The assembly method of the prefabricated structure and the construction method of the joints are a key technology of this type of structure; the joint connection area is the key to ensure that the overall performance of the prefabricated structure meets the structural design requirements. [0003] Shear wall members can have greater lateral stiffness and can effectively bear greater horizontal loads. In today's building ...

AI Technical Summary

Problems solved by technology

The vertical connection methods of prefabricated walls mainly include grout anchor connection and grouting sleeve connection; prefabricated walls often have more steel bars and the diameter of the steel bars is small, making it difficult to align the wall with the grouting channel when hoisting on site ; and during the grouting process, clogging and other phenomena are prone to occur, which will affect the connection performance of the wall

The horizontal connection method of the prefabricated wall is mainly to reserve additional connecting steel bars at the edge of the wall, and pour the connecting area on site; the configuration of the steel bars at the connecting position is relatively dense, which makes the lifting of this connection process difficult, and the assembly process is complicated. Difficult to control quality
