Hanging flexible connection of precast concrete infill wall

Abstract

The invention discloses a hanging flexible connection of a precast concrete infill wall. The hanging flexible connection of the precast concrete infill wall comprises precast concrete infill wall, frame columns / shear walls on both sides of the infill wall, a top beam / plate on the top of the infill wall and a bottom beam / plate at the bottom of the infill wall, wherein the precast concrete infill wall is connected with the frame columns / shear walls on both sides of the infill wall through snapping flexible pull rings, the precast concrete infill wall is connected with the top beam / plate of the infill wall through reserved joint bar grouting or cast-in-place of concrete, and a base slurry layer is arranged between the precast concrete infill wall and the bottom beam / plate of the infill wall. Vertical reinforcing steel bars are inserted into the middle and rear portions of the snapping flexible pull rings. The precast concrete infill wall can be made of light walls with anti-seismic energy dissipation structure. The hanging flexible connection of the precast concrete infill wall solves the technical and theoretical problems of heavy workload of cast-in-place or masonry construction, complex collaboration with a main structure, vulnerability and lack of anti-seismic energy dissipation capacity in earthquake and the like of an existing connection of the infill wall.

Description

technical field [0001] The invention relates to a hanging type flexible connection of a prefabricated concrete filling wall, which belongs to the field of construction engineering structure technology and construction. Background technique [0002] For the construction of infill walls, brick infill walls are often used for cast-in-place concrete structures, and the connection with the main structure is formed by connecting steel bars arranged along the height direction on both sides of the infill walls; prefabricated concrete structures generally use infill walls and main body shear force The wall is prefabricated as a whole or the infill wall is prefabricated separately, and the main structure is anchored or welded through the reserved ribs at the bottom of the infill wall or the pre-embedded steel plates at the four corners. [0003] The existing connection methods mentioned above obviously have shortcomings such as inconvenient construction, heavy on-site workload, and un...

AI Technical Summary

Problems solved by technology

[0003] The existing connection methods mentioned above obviously have shortcomings such as inconvenient construction, heavy on-site workload, and unclear influence of infill wall components on the mechanical performance of the main structure in the cast-in-place concrete structure; ) or the connection is weak (reserved rib anchoring or square steel plate welding), at the same time, its influence on the mechanical performance of the main structure is quite different from that of the traditional cast-in-place structure, and there are not enough design results and experience for reference

[0004] At the same time, in the existing design method, the infill wall is used as a non-structural component, resulting in early damage in the earthquake and lack of seismic energy dissipation capacity, and the performance of the component, especially the seismic performance, is not fully developed

[0005] The above problems have caused the complexity of the construction of the infill wall, the blindness of the design and the reduction of the seismic reliability, which further affects the post-earthquake repair work
