Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of prefabricated building wall, and particularly provides a prefabricated composite shear wall. BACKGROUND

[0002] In the field of construction, prefabricated shear wall structures have been widely used due to their advantages of fast construction speed and controllable quality. In the existing installation method of prefabricated shear walls, a sleeve pipe is usually pre-buried at the bottom of the shear wall, and the steel bars on the bottom surface are inserted into the sleeve pipe, and then concrete is poured to realize the connection between the shear wall and the foundation.

[0003] However, this installation method has significant drawbacks. During the hoisting of the prefabricated shear wall, it is extremely difficult to align the pre-buried sleeve pipe with the steel bars on the bottom surface. Since the sleeve pipe is located at the bottom of the shear wall, it is difficult for the construction personnel to directly observe the relative position of the sleeve pipe and the steel bars, and it is often necessary to use a mirror on the ground to constantly observe and adjust the relative position of the sleeve pipe and the steel bars. This process not only consumes a lot of time and manpower, resulting in low installation efficiency, but also increases the construction cost and safety risk.

[0004] In addition, the existing prefabricated shear wall has poor seismic performance. Only through the connection of the sleeve pipe and the pre-buried steel bars, the connection between the shear wall and the foundation is prone to damage under the action of earthquakes, which cannot effectively transmit and disperse the earthquake force, thereby affecting the stability and safety of the entire building structure. With the increasing demand for building seismic performance, the existing prefabricated shear wall technology has been difficult to meet the needs of actual engineering.

[0054] In the assembly of the shear wall, the shear wall is hoisted, after hoisting, one end of the concrete body 200 with the post-cast pipe 300 is directed towards the connecting part 400, and the concrete body 200 is lowered so that the first pouring unit 420 extends into the post-cast pipe 300, and the second pouring unit 430 is close to the bottom end of the shear wall reinforcement framework 100, then the post-cast pipe 300 and the position close to the second pouring unit 430 of the shear wall reinforcement framework 100 are grouted, and after the concrete grout is solidified, the assembly effect of the concrete body 200 of the shear wall and the building foundation slab 500 or the girder is realized through the connecting part 400.

[0057] Please refer to Figures 1-7In some embodiments, the shear wall steel reinforcement framework 100 comprises a main steel reinforcement frame 110 and columnar steel reinforcement frames 120 arranged on both sides of the main steel reinforcement frame 110; wherein: the two columnar steel reinforcement frames 120 are connected with the main steel reinforcement frame 110 by binding; a connecting steel reinforcement 130 in the shape of a U, the open end of the U-shaped connecting steel reinforcement 130 is connected with the bottom end of the main steel reinforcement frame 110 by binding, and the bottom end is used for grouting connection with the second pouring unit 430; wherein: the bottom end of the U-shaped connecting steel reinforcement 130 extends out of the bottom end of the concrete body 200.

[0058] In the above embodiments, the main steel reinforcement frame 110 is used in the shear wall steel reinforcement framework 100 in combination with the structure of the columnar steel reinforcement frames 120 on both sides instead of a single frame, the columnar steel reinforcement frames 120 are used as edge constraint members to improve the bending bearing capacity and shear stiffness of the shear wall, the dense stirrup restrains the concrete to delay the crushing of the wall end, the failure mode is converted from brittle shear to ductile bending, the strong column energy dissipation and flexible damping effect are formed in cooperation with the seismic damping unit 410 during an earthquake, and the columnar frame, the main frame and the second pouring unit 430 are grouted as a whole by the U-shaped connecting steel reinforcement 130 to disperse the stress peak of the bottom connection and improve the hoisting deformation problem by using the high stiffness characteristics of the columnar frame.

[0059] Please refer to Figures 1-7 In some embodiments, the post-poured pipe 300 comprises: a transverse sleeve body 310, the middle part of which is pre-buried in the main steel reinforcement frame 110, and both ends of which are pre-buried in the two columnar steel reinforcement frames 120; two sets of exhaust pipes 320 are arranged at both ends of the transverse sleeve body 310; wherein: one end of the exhaust pipe 320 away from the transverse sleeve body 310 is arranged obliquely upward and extends out of the side wall of the concrete body 200; a plurality of vertical connecting sleeves 330 are arranged, and each of the vertical connecting sleeves 330 corresponds to one of the connecting parts 400; wherein: the top end of the vertical connecting sleeve 330 is in communication with the transverse sleeve body 310, and the bottom end is used for connecting the first pouring unit 420, and the first pouring unit 420 is arranged in the vertical connecting sleeve 330; a grouting pipe 340 is arranged to pass through the circumferential outer wall of the concrete body 200 and the vertical connecting sleeve 330.
