They are respectively connected with two frame beams 20. The two frame columns 30 are respectively located on both sides of the prefabricated concrete wall panel 10. The prefabricated concrete wall panel 10 is provided with a plurality of first shock-absorbing joints 110 arranged at intervals. A shock-absorbing joint 110 respectively penetrates along the thickness direction of the prefabricated concrete wall panel 10 .

In other words, the fabricated concrete slotted shear wall 100 is mainly composed of frame beams 20 , frame columns 30 and concrete prefabricated wall panels 10 . In the vertical direction, the upper and lower intervals are arranged, a frame column 30 is arranged between the two frame beams 20, the frame column 30 includes two, and the upper and lower ends of each frame column 30 are respectively connected with the two frame beams 20 on the same side. The ends are connected, and the two frame beams 20 cooperate with the two frame columns 30 to form a rectangular frame structure.

Further, the prefabricated concrete wall panel 10 is arranged in a rectangular frame formed by the cooperation of the frame beams 20 and the frame columns 30. The two frame beams 20 are respectively located on the upper and lower sides of the prefabricated concrete wall panel 10, and the two frame columns 30 are respectively located at the upper and lower sides of the prefabricated concrete wall panel 10. On the left and right sides of the wall panel 10 , the prefabricated concrete wall panel 10 is provided with first shock-absorbing joints 110 , and the first shock-absorbing joints 110 include a plurality of first shock-absorbing seams 110 respectively along the length of the prefabricated concrete wall panel 10 . The thickness direction (the front-rear direction as shown in FIGS. 2 and 5 ) penetrates.

Therefore, according to the prefabricated concrete slotted shear wall according to the embodiment of the present invention, by arranging a plurality of first shock absorption joints 110 on the prefabricated concrete wall panel 10 along its thickness direction, a single shear wall can be divided into A plurality of wall members with a larger height-to-width ratio are provided, thereby increasing the deformation ability and ductility of the prefabricated concrete wall panel 10. During the deformation process of the prefabricated concrete wall panel 10, relative friction occurs on the two sides of the first shock-absorbing joint 110. The first shock-absorbing joint 110 deforms and consumes energy during the friction process. Under the action of an earthquake, the first shock-absorbing joint 110 can reduce the deformation and damage of the prefabricated concrete wall panel 10, and the arrangement is flexible, the construction period is short, and the cost is saved. Human resources and post-earthquake recovery costs.

The first shock-absorbing joints 110 extend in the direction (the left-right direction as shown in FIG. 1 ), and each first shock-absorbing joint 110 extends along the length direction of the prefabricated concrete wall panel 10 (the up-down direction as shown in FIG. 2 ), The upper and lower ends of each first shock absorbing joint 110 are spaced apart from the upper and lower edges of the prefabricated concrete wall panel 10 , and the lengths of the two side surfaces of the first shock absorbing joints 110 are the same. There are certain intervals.

It should be noted here that if the extension of the first shock absorption joint 110 in the vertical direction is small, the ductility of the prefabricated concrete wall panel 10 will be small, and if the extension is too large, the stiffness loss of the prefabricated concrete wall panel 10 will be large. Therefore, the extent to which the first shock absorbing seam 110 extends in the vertical direction can be determined according to the actual project.

Wherein, by arranging several first damping joints 110 spaced apart on the prefabricated concrete wall panel 10, when the prefabricated concrete slotted shear wall 100 is subjected to an external force and the acting force is small, the first damping joints 110 are two The prefabricated concrete wall panel 10 on the side will generate relative dislocation consumption force, which can reduce the damage degree of the prefabricated concrete wall panel 10, not only can ensure the strength and rigidity of the prefabricated concrete wall panel 10, but also increase the strength of the prefabricated concrete wall panel 10.
