[0002] When masonry wall structures are subjected to earthquakes, they typically experience damage, instability, deformation, and cracks. Measures are taken to stabilize the structure and reduce the damage. Under earthquake action, it is hoped that the functional use of the masonry wall structure will be maintained as high as possible. Even in cases of minor damage, these measures provide effective support and dissipate seismic energy, thus preventing further damage to the masonry wall structure and minimizing the impact of earthquakes on people's lives. Utility Model Content

[0003] The purpose of this invention is to provide a shock-absorbing and energy-enhancing masonry structure reinforcement device, which solves the problem of masonry walls becoming unstable and collapsing during earthquakes in the existing technology.

[0004] The technical solution adopted by this utility model is a vibration-damping and energy-dissipating enhanced masonry structure reinforcement device, including a masonry wall. The bottom two corners of the masonry wall are connected to bases, and the top two corners of the masonry wall are connected to upper seats. The two upper seats are symmetrically connected to side support bars, and SMA rods are connected between the two side support bars. A frame and a pole are connected between the corresponding bases and upper seats. The poles are located inside the frame, and multiple horizontal bars are connected between the two poles. Two first sliders are symmetrically connected to the two ends of the two frames.

[0005] It also includes a base plate, on which sliding devices are symmetrically connected on both sides of the upper surface of the base plate. The sliding devices are hinged to the first slider at the top of the upright frame via a diagonal rod, and a telescopic rod is hinged between the diagonal rod and the first slider at the bottom of the upright frame.

[0006] The feature of this utility model is that,

[0007] Both uprights have long through holes in the vertical direction, and both sides of the two first sliders have through holes. The uprights and the two first sliders are connected by high-strength bolts and nuts.

[0008] The sliding device includes two slide grooves, which are symmetrically fixed to both sides of the upper surface of the base plate. Each slide groove is equipped with a second slider and a compression spring. The second slider is connected to the compression spring. Supports are connected to both the first slider and the second slider. One end of the inclined rod is hinged to the support on the second slider, and the other end of the inclined rod is hinged to the support on the first slider at the top of the stand.

[0009] The diagonal rod is connected to a support near the side wall of the base plate. One end of the telescopic rod is hinged to the support on the first slider at the bottom of the upright, and the other end is hinged to the support near the side wall of the base plate. A compression spring is installed inside the telescopic rod.

[0010] The support is connected to the first slider, the second slider, and the diagonal rod by high-strength bolts and nuts, respectively.

[0011] Each horizontal bar has a locking device welded to both ends, and the horizontal bar is connected to the vertical bar through the locking device.

[0012] The locking device includes a top plate, an elastic element, and a locking component, with slots on both sides of the locking component.

[0013] The base plate has a through hole, and a positioning pin is installed in the through hole. The base plate is connected to the ground through the positioning pin.

[0014] The base and the upper seat are respectively connected to the corner of the masonry wall by screws and lock nuts.

[0015] The beneficial effects of this utility model are:

[0016] (1) The vibration-damping and energy-dissipating enhanced masonry structure reinforcement device provided by this utility model has a frame set on the upper seat and the base. The sliding adjustment of the slider set on the frame allows the inclined rod and the telescopic rod to fully support the masonry wall. At the same time, the movement of the slider drives the inclined rod to generate elastic force on the compression spring and the telescopic rod to compress the elastic force of the compression spring, so as to achieve a double vibration reduction effect through the compression spring and the telescopic rod compression spring, effectively dissipating most of the earthquake energy, thereby realizing the vibration reduction effect on the masonry wall.

[0017] (2) The vibration-damping and energy-dissipating enhanced masonry structure reinforcement device provided by this utility model has upper seats and bases fixed at the four corners of the masonry wall. SMA rods are connected between the left and right side support bars between the upper seats to provide support. The SMA rods are replaceable devices and are easy to replace after an earthquake. The upper seats and bases are equipped with uprights, and self-locking devices are arranged at both ends of the horizontal bars to facilitate the connection between the horizontal bars and the uprights to support the masonry wall. The position of the horizontal bars can be adjusted according to the condition of the masonry wall, and the masonry wall can be fully supported by moving the uprights up and down.

[0023] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0024] Example 1

[0025] This utility model provides a vibration-damping and energy-dissipating enhanced masonry structure reinforcement device, such as... Figure 1 , Figure 2 and Figure 3 As shown, bases 3 are installed at the two bottom corners of the masonry wall 1, and upper seats 4 are installed at the two top corners. Bases 3 and upper seats 4 are connected by screws 21 and locking nuts 22. Upper seats 4 are connected to side support bars 6 by high-strength bolts 19. SMA rods 7 are connected between the left and right side support bars 6 for support. Bases 3 and upper seats 4 are fixed by vertical connections via uprights 5 and uprights 8. Locking devices 9 are welded to both ends of the horizontal bar 10. Figure 4 As shown, the locking device consists of a top plate 901, an elastic element 902, and a locking component 903 with slots on both sides. The vertical rod pushes open the locking component 903 with slots on both sides and compresses the elastic element 902 to form a locking groove for fixation. Two first sliders 11 are distributed on the upright frame 5. The two first sliders 11 have through holes. The side wall of the upright frame 5 has a long through hole. The bolt passes through the long through hole and the through hole and is positioned by the nut. A sliding groove 14 is fixed on the bottom plate 2 and connected to the ground by the positioning nail 18. A compression spring 17 is installed in the sliding groove 14 and connected to the second slider 15 with a support 16. The support 16 is fixed to the second slider 15 by high-strength bolts 19 and nuts 20 respectively. An inclined rod 12 is hinged between the support 16 on the first slider 11 and the support 16 on the second slider 15. A support 16 is provided on the lower side of the inclined rod 12 and a telescopic rod 13 is hinged between the support 16 on the bottom first slider 11 and the support 16 on the bottom first slider 11 for full support.

[0026] The telescopic rod is equipped with a compression spring. As the telescopic rod moves, the compression spring maintains support and fixation for the masonry wall 1. The support 16 has bolt holes and is connected by high-strength bolts. The two are connected one-to-one and should be strictly installed according to requirements.

[0027] The base plate 2 is made of high-strength steel plate with holes. It is connected to the ground by positioning nails 18. The SMA rod 7 can be prestressed in advance so that the device is always under tension and can provide full support for the masonry wall.

[0028] The vibration-damping and energy-dissipating enhanced masonry structure reinforcement device provided by this utility model has the following working principle:

[0029] Under minor earthquake action, the SMA rods 7 connecting the left and right side bracing bars 6 provide sufficient support for the upper part of the masonry wall. The horizontal bar 10 is connected to the vertical bar 8 through the locking device 9. The compression elastic element of the vertical bar is locked into the locking device 9. The locking device 9 moves up and down and connects with the vertical bar 8 to fix the masonry wall 1, thereby effectively supporting and reinforcing the middle and lower part of the masonry wall 1.

[0030] Under a large earthquake, the seismic action overcomes the initial resistance and is fixed by the diagonal rod 12 and the telescopic rod 13. The upper and lower sliders move on the frame 5 and drive the diagonal rod 12 and the telescopic rod 13 to maintain support for the masonry wall 1. At the same time, the compression spring is generated and the telescopic rod compresses the spring. Most of the seismic energy is consumed by the compression spring, so that the structure obtains passive control force, which facilitates effective support and reinforcement of the masonry wall 1.
