Abstract

The invention belongs to the technical field of building structures of civil engineering, and discloses a replaceable connecting joint for wallboard components of precast concrete shear wall structures. The replaceable connecting joint comprises a first precast concrete shear wallboard (1), a second precast concrete shear wallboard (2) and joint components (3), and the first precast concrete shear wallboard (1) is connected with the second precast concrete shear wallboard (2) via the joint components (3). Under effects of middle and large earthquakes, the replaceable component is yielded or damaged so as to avoid damage of the wallboards, and simultaneously, replacement and repair after the earthquakes are further realized conveniently. The replacement connecting joint is simple in design idea, and convenient in manufacture and construction. A building process is environment-friendly and energy-saving, and cost is reduced. Accordingly, the replacement connecting joint is suitable for the aseismatic design field of industrial precast concrete shear wall structures of houses.

Description

technical field [0001] The invention belongs to the technical field of building structures of civil engineering, and relates to a replaceable connection node of a prefabricated concrete shear wall structure wall plate member. 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 met...
