Problems solved by technology

[0004] The above-mentioned connection methods and connection nodes either use the concept of post-cast strips or the method of pre-embedded anchoring steel rings to connect wall panels. Insufficient anchorage or too little or no reinforcement in the connection area does not fully guarantee reliable and effective connection between wall panel members

Abstract

The invention belongs to the technical field of building structures in civil engineering, and discloses a method for connecting wallboard components of a precast concrete shear wall structure, which includes the steps: bending respective reinforcing bars, extending out of lateral edges of wallboards, of a first precast concrete shear wallboard (1) and a second precast concrete shear wallboard (2) to form closed rectangular reinforcing bar rings (3), overlapping the closed rectangular reinforcing bar rings, and using a joint reinforced concrete beam (4) to connect the wallboards. The method is simple in design concept and convenient in production, processing and construction, no complex mechanical equipment or implement is needed in construction, no power is consumed in construction, the construction is environment-friendly, energy-saving, cost-reducing and low in construction funds, the advantage of quick construction speed of the precast concrete structure can be given to full play evidently, and the method can be widely applied to the field of aseismic design of high-rise building precast concrete shear wall structures.

Description

technical field [0001] The invention belongs to the technical field of building structures of civil engineering, and relates to a connection method for wall panel components of a prefabricated concrete shear wall structure. Background technique [0002] With the proposal of housing industrialization and construction industrialization, and in response to the call for building energy-saving and environment-friendly buildings, prefabricated concrete structures have begun to be popularized and applied nationwide. As a structural system with high lateral stiffness and mainly used to resist horizontal and vertical actions, shear wall structure is mainly used in the construction of small high-rise residential buildings (12-30 floors). In the precast concrete shear wall structure, the connection area between the precast concrete wall panel components is the most sensitive part in the precast shear wall structure, and it is also the weakest link of the structure. The connection metho...
