Problems solved by technology
However, the current prefabricated reinforced concrete shear wall has the disadvantages of insufficient strength, difficult installation and uneconomical due to the complex structure of the horizontal joint connection.
[0003] The current recoverable functional shear wall is mainly to symmetrically install energy dissipation dampers at the corners of both sides of the shear wall to realize energy dissipation, but this method will reduce the horizontal bearing capacity of the shear wall

The invention discloses a prefabricated wallboard of a function-variable fabricated bidirectional self-locking-type shear wall. The prefabricated wallboard comprises wallboard bodies, self-locking-type grooves are formed in any two opposite side faces of each wallboard body correspondingly, the bottom face of each self-locking-type groove forms an angle with the side faces of the wallboard body where the self-locking-type groove is located, the included angle between the bottom face of each self-locking-type groove and the side faces of the wallboard body where the self-locking-type groove islocated is not larger than a friction angle, and the two self-locking-type grooves in each wallboard body are formed parallelly. The prefabricated wallboard of the function-variable fabricated bidirectional self-locking-type shear wall is provided with the self-locking-type grooves and reserved holes, and thus combined mounting is convenient; and according to the function-variable fabricated bidirectional self-locking-type shear wall, by pouring concrete into the self-locking-type grooves and meanwhile through cooperation of longitudinal carrying bars and a tension and compression combined damper, the shear wall has good earthquake energy dissipation capacity while having good carrying performance.
Description
technical field [0001] The invention belongs to the technical field of building structures, and relates to a recoverable function assembled two-way self-locking shear wall, and also relates to a recoverable function assembled two-way self-locking shear wall prefabricated wall panel. Background technique [0002] Shear wall is an important component of high-rise buildings, which can effectively bear vertical and horizontal loads, and has high strength, stiffness and seismic performance. However, the prefabricated shear walls commonly used in my country are mainly composed of prefabricated parts and cast-in-place parts, which have the advantages of saving formwork, fast construction speed and good integrity of cast-in-place. However, the current prefabricated reinforced concrete shear wall has the disadvantages of insufficient strength, difficult installation and uneconomical due to the complex structure of the horizontal joint connection. [0003] The current recoverable fun...
