In other words, the prefabricated concrete slotted shear wall 100 is mainly composed of frame beams 20, frame columns 30 and concrete prefabricated wall panels 10, the frame beams 20 include two, each frame beam 20 extends along the horizontal direction, and the two frame beams 20 In the vertical direction, arranged at intervals up and down, frame columns 30 are arranged between the two frame beams 20. The ends are connected, and two frame beams 20 cooperate with two frame columns 30 to form a rectangular frame structure.

Further, the prefabricated concrete wall panel 10 is arranged in a rectangular frame composed of frame beams 20 and frame columns 30, the two frame beams 20 are respectively located on the upper and lower sides of the precast concrete wall panel 10, and the two frame columns 30 are respectively located on 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 damping joints 110, and the first damping joints 110 include a plurality of first damping joints 110 along the sides of the precast concrete wall panel 10. The thickness direction (the front-rear direction as shown in FIGS. 2 and 5 ) runs through.

Therefore, according to the prefabricated concrete slotted shear wall of the embodiment of the present invention, a single shear wall can be divided into Multiple wall piers with larger aspect ratios, thereby increasing the deformation capacity and ductility of the prefabricated concrete wall panel 10. During the stress deformation process of the prefabricated concrete wall panel 10, the two sides of the first damping joint 110 will rub against each other. The first damping joint 110 deforms and consumes energy during the friction process. Under the action of an earthquake, the first damping joint 110 can reduce the deformation and damage of the concrete prefabricated wall panel 10, and the layout is flexible, the construction period is short, and the construction cost is saved. Human resources and post-earthquake recovery costs.

Optionally, each first shock-absorbing slot 110 extends substantially along a vertical direction, and a plurality of first shock-absorbing slots 110 are arranged at intervals along a horizontal direction.

Specifically, as shown in Fig. 2 and Fig. 5, the concrete prefabricated wall panel 10 forms a panel extending in the vertical direction (up and down as shown in Fig. 2), and the concrete prefabricated wall panel 10 is provided with a plurality of direction (the left-right direction as shown in Figure 1 ), and each first shock-absorbing joint 110 extends along the length direction of the concrete prefabricated wall panel 10 (the up-down direction as shown in Figure 2 ), The upper and lower ends of each first damping joint 110 are spaced apart from the upper and lower edges of the concrete prefabricated wall panel 10, and the lengths of the two sides of the first damping joint 110 are the same, and the distance between adjacent first damping joints 110 There is a certain interval.

What needs to be explained here is that if the extension of the first damping joint 110 in the vertical direction is small, the ductility of the concrete precast wall panel 10 will be small, and if the extension is too large, the rigidity of the concrete precast wall panel 10 will be greatly lost. Therefore, the extent to which the first damping seam 110 extends in the vertical direction can be determined according to actual engineering,

Wherein, by setting several first damping joints 110 arranged at intervals on the prefabricated concrete wall panel 10, when the prefabricated concrete slotted shear wall 100 is subjected to an external force and the force is small, the first damping joints 110 will The concrete prefabricated wall panels 10 on the side will produce relative stagger consumption force, which can reduce the damage degree of the concrete prefabricated wall panels 10, not only can ensure the strength and rigidity of the concrete prefabricated wall panels 10, but also increase the strength of the concrete prefabricated wall panels 10.

That is to say, the first shock-absorbing joint 110 on the prefabricated concrete wall panel 10 is provided with an energy-dissipating material piece, which is fixedly installed in the first shock-absorbing joint 110, and the end surfaces on both sides of the energy-dissipating material piece stop against Connected on the inner wall of the concrete prefabricated wall panel 10. By setting the first damping joint 110 on the prefabricated concrete wall panel 10, the wall is divided into several wall piers with larger height-to-width ratios. During an earthquake, the first damping joint 110 is also deformed due to the deformation of the wall. The energy-dissipating materials or energy-dissipating components in the joints will consume energy and absorb the earthquake energy, thereby enhancing the deformation resistance and ductility of the building, and the layout is flexible, the construction period is short, and the human resources and post-earthquake restoration costs are saved.

Thus, by arranging energy-dissipating material pieces between the walls on both sides of the first damping joint 110, the friction or deformation of the energy-dissipating material pieces can consume the deformation energy, and the prefabricated concrete wall panel 10 is deformed under force. The wall surfaces on both sides of the first damping joint 110 are relatively displaced, and the energy-dissipating material parts are deformed accordingly. 10 degrees of destruction.

Furthermore, the viscoelastic energy-dissipating material plate 12 made of viscoelastic material not only has a damping effect, but also can be closely attached to the wall of the first damping joint 110 to further ensure its damping effect. The plate 12 plays the role of consuming the deformation energy. The prefabricated concrete wall panel 10 is deformed under the force, and the walls on both sides of the first damping joint 110 are relatively displaced, and the viscoelastic energy-dissipating material plate 12 is correspondingly deformed. The energy-dissipating material board 12 can absorb the deformation energy of the prefabricated concrete wall panel 10 during the deformation process, thereby reducing the damage degree of the prefabricated concrete wall panel 10 .
