Dry type connected concrete shear wall and dry type wall connecting method

Abstract

The invention relates to a dry type connected concrete shear wall which is composed of sleeves, nuts, metal connecting pieces and precast concrete shear wall bodies. Vertical steel bars are vertically and uniformly arranged in the precast concrete shear wall bodies, and anchoring steel bars are transversely arranged on the upper sides and the lower sides in the precast concrete shear wall bodies. The vertical steel bars of the adjacent precast concrete shear wall bodies are connected through the sleeves at the aligning positions of the vertical steel bars. The two ends of each metal connecting piece are separately provided with circular holes. The two ends of every two anchoring steel bars at the aligning and connecting positions of the corresponding adjacent precast concrete shear wall bodies are connected through the circular holes of the corresponding metal connecting pieces in an aligning mode. The two ends of each anchoring steel bar are provided with threads, and the metal connecting pieces are fastened to the two ends of the anchoring steel bars through the nuts. According to the dry type wall connecting method, dry operation construction is adopted, and construction is simplified; and the dry type connected concrete shear wall is reliable in connection and good in integrity and has superior seismic resistance, the number of the connecting pieces is decreased, and the industrialization efficiency of the concrete shear wall is remarkably improved.

Description

technical field [0001] The invention belongs to the field of prefabricated concrete shear walls, and in particular relates to a dry connection method between a concrete shear wall and a wall. Background technique [0002] In the past few decades, my country's construction industry has flourished, which has greatly promoted the growth of the national economy. Faced with the increase of land transfer fees in our country, the continuous rise of labor prices, and the gradual improvement of people's awareness of energy conservation and environmental protection requirements, the construction industry is facing increasing pressure from international competition. In order to improve the core competitiveness, a new industry model - prefabricated buildings came into being. [0003] Prefabricated concrete structures refer to concrete structures assembled by prefabricated concrete components through reliable connection methods, including assembled integral concrete structures, fully as...
