Description

Technical Field

[0001] The present invention relates to the technical field of coupling beam reinforcement, and particularly relates to a coupling beam reinforcement structure and a reinforcement method with high seismic performance. Background Art

[0002] Reinforced concrete shear wall structures play an important role in various high-rise structural systems due to their large lateral stiffness and high bearing capacity. Plastic hinges are formed at the ends of coupling beams to dissipate seismic energy. To meet the requirements of continued use and performance improvement of buildings, it is necessary to reinforce the coupling beams. A coupling beam refers to a beam that connects walls to walls within the plane of the wall in a shear wall structure and a frame-shear wall structure. Coupling beams generally have the characteristics of small span and large cross-section, and the stiffness of the walls connected to the coupling beams is very large. Generally, under wind loads and seismic actions, the internal forces of the coupling beams are often very large; when encountering seismic actions, energy will be transmitted to the shear walls through the coupling beams. After multiple earthquakes, the shear walls are prone to serious damage and even collapse. Summary of the Invention

A number of hollow rods 19 are fixedly installed on the side of the moving plate 25 away from the connecting rod 23. A slider 21 is slidably arranged in the hollow rod 19. One side of the slider 21 away from the moving plate 25 is fixedly connected with a sliding rod 26.

One end of the return spring 20 is fixedly connected with the slider 21, and the other end of the return spring 20 is fixedly connected with the inner wall of the hollow rod 19.

[0038] Among them, preferably, the lateral seismic resistance assembly includes four air boxes 14. The four air boxes 14 are fixedly installed in pairs on one side of the coupling beam 9 close to each other. An air pipe 15 is connected through the air box 14.

[0040] The working principle and beneficial effects of the above technical solution are as follows: When an earthquake occurs, the coupling beam 9 will drive the second stopper 22 and the connecting rod 23 to move left and right. The connecting rod 23 drives the moving plate 25 to move left and right. The first damper 24 buffers and absorbs energy. When the moving plate 25 moves left and right, the slider 21 will move left and right within the hollow rod 19. The slider 21 drives the sliding rod 26 to move left and right. The return spring 20 buffers and absorbs energy; when the coupling beam 9 moves left and right, the coupling beam 9 drives the air box 14 to move left and right, thereby changing the position of the air plate 13 within the air box 14. The air plate 13 blows the gas within the air box 14 into the airbag 10. As the airbag 10 expands, the airbag 10 will press against the shape memory alloy sheet 8, thereby achieving the effect of buffering and shock absorption; by setting the first damper 24, the return spring 20 and the airbag 10, when an earthquake comes, it can effectively achieve the effect of buffering and shock absorption, effectively slow down the earthquake energy, reduce the destructive force, and effectively improve the safety and practicality.

[0041] Embodiment 3

Second dampers 30 are symmetrically installed on the left and right within the through groove 12. A buffer block 29 is fixedly installed on the side where the second dampers 30 are close to each other. The buffer block 29 abuts against the extension rod 27.

[0043] Among them, preferably, the diameter of the circular stopper 28 is greater than the width of the through groove 12.

[0044] Among them, preferably, the side where the buffer blocks 29 are close to each other is set to be arc-shaped.

[0045] Among them, preferably, the buffer assembly includes a buffer box 31 and a buffer rod 32, the buffer box 31 and the buffer rod 32 are respectively fixedly arranged on one side of the left-right symmetrical mounting plate 4 close to each other, the buffer box 31 and the buffer rod 32 are distributed left and right, the buffer rod 32 extends into the buffer box 31, and the buffer rod 32 is slidably connected to the extended position of the buffer box 31, a sliding plate 33 is slidably provided in the buffer box 31, the sliding plate 33 is fixedly connected to the buffer rod 32, and a plurality of buffer springs 34 are fixedly connected to the other end of the sliding plate 33, and the buffer springs 34 are fixedly connected to the inner wall of the buffer box 31.

[0046] The working principle and beneficial effects of the above technical solution are as follows: when the connecting beam 9 moves left and right, the second fixing member 5 will also move left and right, the second fixing member 5 drives the extension rod 27 to move left and right, the extension rod 27 drives the buffer block 29 to move left and right, the second damper 30 buffers and absorbs energy, when the second damper 30 is not enough to absorb all the energy, the mounting plate 4 will move left and right, the sliding plate 33 will move left and right in the buffer box 31, and the buffer spring 34 will continuously compress and stretch to absorb energy; by setting the second damper 30 and the buffer spring 34, the energy of the earthquake can be further reduced, and the energy transferred to the shear wall 1 can be reduced; when an earthquake occurs, there will be not only horizontal vibrations, but also vertical vibrations. When the two connecting beams 9 move up and down alternately, the mounting plate 4 will deflect counterclockwise or clockwise, thereby making the buffering and shock absorption of the second damper 30 and the buffer spring 34 more convenient, effectively improving the practicality of the device.

In addition, due to the cooperation of the through slot 12 on the mounting plate 4 and the extension rod 27, when the mounting plate 4 deflects, the through slot 12 will also deflect, and the contact positions of the two buffer blocks 29 with the extension rod 27 change. Therefore, when the two coupling beams 9 are staggered up and down, the second damper 30 and the buffer spring 34 can also conveniently mitigate the earthquake energy, effectively improving the practicability.
