[0002] A damper is a device that provides resistance to movement and dissipates kinetic energy. In the field of construction engineering, in order to improve the seismic strength of concrete, self-resetting friction dampers are generally installed on concrete frames to resist the vibrations caused by earthquakes through the resistance provided by the damper.

[0003] During the installation process of the self-resetting damper, the two ends of the damper are generally placed between two walls, and then concrete is poured at the connection position to connect them. Due to the limited contact area between the poured concrete and the damper, the connection strength between the damper and the concrete frame is low, thereby reducing the strength of the seismic structure. Summary of the Invention

[0016] By adopting the above technical solution, the upper end of the mounting buckle can be shielded and protected, thereby preventing dust generated at the construction site from accumulating on the mounting buckle and affecting the rotation between the oil cylinder and the output shaft and the mounting buckle.

[0017] Preferably, an elastic loop is sewn on the surface of the elastic cloth by needle and thread, and the size of the elastic loop is adapted to the size of the elastic cloth.

At this time, the elastic cloth will cover the top of the mounting buckle. During construction, dust and other debris generated will be blocked by the elastic cloth to the outside, thereby achieving the effect of shielding and protecting the inner wall of the mounting buckle. The elastic ring avoids cracking at the edge of the elastic cloth. By providing a protective structure, the mounting buckle can be shielded and protected, thereby preventing dust generated at the construction site from falling into the mounting buckle, affecting the normal rotation between the oil cylinder and the output shaft and the mounting buckle.

[0039] Example 1, as Figure 1-8 As shown, the present invention provides an assembled concrete frame seismic resistant structure including a self-resetting friction damper, including two walls 1 and a reinforcement structure 5. The two walls 1 are each provided with a mounting buckle 3 on one side close to each other. The two mounting buckles 3 are respectively rotatably connected to an oil cylinder 4 and an output shaft 2 on one side close to each other. The oil cylinder 4 is sleeved on the arc surface of the output shaft 2. The surface of the mounting buckle 3 is provided with two reinforcement structures 5. The two reinforcement structures 5 are centrally symmetrically arranged with the center of the mounting buckle 3 as the center of symmetry. The surface of the mounting buckle 3 is provided with a protective structure 6, and the arc surface of the oil cylinder 4 is provided with a cleaning structure 7.

[0040] The specific configuration and functions of the reinforcement structure 5, the protection structure 6 and the cleaning structure 7 will be described in detail below.

[0041] like Figure 3 and Figure 4As shown, the reinforcement structure 5 includes a rotating rod 501, which is rotatably connected to the surface of the mounting buckle 3. The end of the rotating rod 501 away from the mounting buckle 3 is fixedly connected to a fixing plate 502, and the side of the fixing plate 502 close to the mounting buckle 3 is fixedly connected to a clamping rod 503. The arc surface of the clamping rod 503 is slidably connected to an adjustment frame 504. The size of the adjustment frame 504 is half the size of the fixing plate 502. The surface of the adjustment frame 504 is fixedly connected to a reinforcement member 505. The mounting buckle 3 and the two reinforcement members 505 can be directly placed in the poured concrete, and then the fixing plate 502 is rotated to extend the two reinforcement members 505 in the concrete. , and then wait for the concrete to solidify, thereby achieving the effect of improving the installation strength between the installation buckle 3 and the wall 1, the end of the reinforcement 505 away from the adjustment frame 504 is subjected to high-temperature bending treatment, the bending angle range of the reinforcement 505 is 60-90 degrees, the end of the reinforcement 505 away from the adjustment frame 504 is fixedly connected with a sharp plate 512, the end of the sharp plate 512 away from the reinforcement 505 is a sharp end, and the high-temperature bending treatment is used to improve the overall strength of the reinforcement 505, and the bending of the reinforcement 505 has the effect of increasing the contact area between the reinforcement 505 and the concrete, thereby improving the connection strength between the reinforcement 505 and the installation buckle 3, the sharp plate 5 12 plays the effect that makes the reinforcement member 505 extend into the concrete better, the arc surface of the rotating rod 501 is fixedly connected with the circular plate 506, and a plurality of slots 507 are evenly opened on the surface of the circular plate 506, and the edge position of the slot 507 of the circular plate 506 is rounded, and a fixing strip 508 is fixedly connected to one side of the mounting buckle 3, and the fixing strip 508 is internally threaded with a screw 509, and the size of the screw 509 is adapted to the size of the slot 507 of the circular plate 506, so that the screw 509 can be inserted into the slot 507 of the circular plate 506 by means of the thread of the screw 509, thereby fixing the position of the fixing plate 502. The rounded corners make it easier for the screw 509 to be inserted into the slot 507. One side of the mounting buckle 3 is fixedly connected to the limit frame 510. The inner wall of the limit frame 510 is slidably connected to a handle 511. The handle 511 is fixedly connected to the surface of the fixed plate 502, which makes it convenient for the installer to pull the fixed plate 502 for rotation. The reinforcement 505 is fixedly connected to the side of the mounting buckle 3 close to the limit block 513. The surface of the limit block 513 is slidably connected to a slide rail 514. The slide rail 514 is fixedly connected to the surface of the mounting buckle 3, which limits the moving position of the reinforcement 505, thereby allowing the reinforcement 505 to better extend into the concrete.

[0042] The effect achieved by the entire reinforcement structure 5 is that when the mounting buckle 3 needs to be installed on the wall 1, the mounting buckle 3 is first placed directly in the concrete, and then the handle 511 is pulled to make the handle 511 slide along the inner wall of the limit frame 510. The handle 511 will drive the fixed plate 502 to rotate, and the fixed plate 502 will drive the clamping rod 503 to move. The clamping rod 503 begins to push the adjustment frame 504 to move, and the movement of the adjustment frame 504 will drive the reinforcement 505 to move. At this time, the two reinforcements 505 of the same mounting buckle 3 will extend from the mounting buckle 3, and the reinforcement 505 will extend in the concrete. When the reinforcement 505 moves, it will drive the limit block 513 to move, and the limit block 513 will slide along the inner wall of the slide rail 514 of the mounting buckle 3. The limit block 513 and the slide rail 514 have the effect of limiting the moving position of the reinforcement 505. After the component 505 is moved to the appropriate position, the screw 509 is rotated so that the screw 509 is squeezed into the groove 507 of the circular plate 506 by means of the thread, thereby fixing the position of the circular plate 506. When the concrete becomes dry, the reinforcement 505 will be installed in the concrete. By setting the reinforcement structure 5, the reinforcement 505 can be stretched in the concrete, thereby increasing the contact area between the installation buckle 3 and the concrete, and increasing the connection strength between the installation buckle 3 and the wall 1. The reinforcement 505 adopts a continuous bending processing method, which greatly increases the contact area between the reinforcement 505 and the concrete, and when the concrete is not dry, increases the resistance of the reinforcement 505 in the concrete, thereby achieving the effect of facilitating the rapid positioning of the installation buckle 3. The pointed plate 512 facilitates the insertion of the reinforcement 505 into the concrete.

[0043] like Figure 5 and Figure 6 As shown, the protective structure 6 includes four mounting blocks 61, and the four mounting blocks 61 are grouped in twos. The two groups of mounting blocks 61 are respectively clamped on both sides of the mounting buckle 3. The sides of the two groups of mounting blocks 61 close to each other are fixedly connected with a connecting buckle 62, and the sides of the two connecting buckles 62 close to each other are fixedly connected with a spring 63. The side of the connecting buckle 62 away from the mounting buckle 3 is slidably inserted with a sleeve rod 64, and the arc surface of the two sleeve rods 64 is fixedly connected with an elastic cloth 65, which achieves the effect of shielding and protecting the upper end of the mounting buckle 3, and prevents dust generated at the construction site from accumulating on the mounting buckle On the mounting buckle 3, a situation that affects the rotation between the oil cylinder 4 and the output shaft 2 and the mounting buckle 3 occurs. An elastic ring 66 is sewn on the surface of the elastic cloth 65 with needle and thread. The size of the elastic ring 66 is adapted to the size of the elastic cloth 65, thereby achieving the effect of reinforcing the edge of the elastic cloth 65 and avoiding cracking of the edge of the elastic cloth 65. The internal sliding connection of the spring 63 is connected to the limit rod 67, and the two ends of the limit rod 67 slide through the two connecting buckles 62 respectively, thereby achieving the effect of limiting the direction of the elastic force of the spring 63 and the moving position of the connecting buckle 62.

[0044] The effect achieved by the entire protective structure 6 is that after the mounting buckle 3 is installed on the wall 1, the two connecting buckles 62 are pulled to move the two connecting buckles 62 in the direction away from each other. At this time, the spring 63 is in a stretched state, and then the two connecting buckles 62 are buckled on both sides of the mounting buckle 3. Then, the connecting buckle 62 is released, and the spring 63 will give the two connecting buckles 62 elastic force, so that the connecting buckle 62 drives the mounting block 61 to be stuck on the mounting buckle 3, thereby achieving the effect of temporarily fixing the position of the sleeve rod 64. At this time, the elastic cloth 65 will cover the top of the mounting buckle 3. During construction, dust and other debris generated will be blocked by the elastic cloth 65 to the outside, thereby achieving the effect of shielding and protecting the inner wall of the mounting buckle 3. The elastic ring 66 prevents the edge of the elastic cloth 65 from cracking. By setting up the protective structure 6, the mounting buckle 3 can be shielded and protected, thereby preventing dust generated on the construction site from falling into the mounting buckle 3, affecting the normal rotation between the cylinder 4 and the output shaft 2 and the mounting buckle 3.

[0045] like Figure 7 and Figure 8 As shown, the cleaning structure 7 includes a slip ring 71, which is slidably connected to the arc surface of the oil cylinder 4, and a pressure rod 77 is threadedly inserted into the arc surface of the slip ring 71, and a connecting plate 72 is welded to the arc surface of the slip ring 71. An adjusting ring 73 is fixedly connected to one side of the connecting plate 72, and a pull rope 75 is slidably inserted into the arc surface of the adjusting ring 73. The arc surface of the adjusting ring 73 is fixedly connected to the cleaning ring 74, so that the output shaft 2 can be cleaned in real time when it is reset after being stretched in the event of an earthquake, so as to avoid the situation where a lot of dust on the surface of the output shaft 2 enters the oil cylinder 4. The arc surface of the slip ring 71 is fixedly connected to three handles 76, and the three handles 76 are evenly distributed on the arc surface of the slip ring 71, so that it is convenient for the operator to pull the slip ring 71 to move, and then facilitate the adjustment of the position of the adjusting ring 73.

[0046] The effect achieved by the entire cleaning structure 7 is that the pull ropes 75 at both ends of the cleaning ring 74 are passed through the adjusting ring 73, and then the pull rope 75 is tied. At this time, the cleaning ring 74 will contact the arc surface of the output shaft 2, and then the handle 76 is pulled. The handle 76 drives the slip ring 71 to move, so that the slip ring 71 slides along the arc surface of the oil cylinder 4. The slip ring 71 drives the adjusting ring 73 to move with the help of the connecting plate 72. When the adjusting ring 73 moves to the appropriate position, the pressure rod 77 is rotated so that the pressure rod 77 is squeezed on the oil cylinder 4 with the help of the thread, thereby fixing the position of the slip ring 71. When the output shaft 2 is reset and retracted into the oil cylinder 4, the output shaft 2 will contact the cleaning ring 74, and the cleaning ring 74 has the effect of cleaning the arc surface of the output shaft 2. By setting the cleaning structure 7, the output shaft 2 can be cleaned in real time when it is retracted into the oil cylinder 4.

[0047] Example 2, on the basis of Example 1, the cleaning structure 7 includes a slip ring 71, which is slidably connected to the arc surface of the oil cylinder 4, and a pressure rod 77 is threadedly inserted into the arc surface of the slip ring 71, and a connecting plate 72 is welded to the arc surface of the slip ring 71, and an adjusting ring 73 is fixedly connected to one side of the connecting plate 72, and a pull rope 75 is slidably inserted into the arc surface of the adjusting ring 73, and a cleaning ring 74 is fixedly connected to the arc surface of the pull rope 75, so that the output shaft 2 can be cleaned in real time when it is reset after being stretched in an earthquake, so as to avoid the situation where a lot of dust on the surface of the output shaft 2 enters the oil cylinder 4, and three handles 76 are fixedly connected to the arc surface of the slip ring 71, and the three handles 76 are evenly distributed on the arc surface of the slip ring 71, so that it is convenient for the operator to pull the slip ring 71 to move, and then to adjust the position of the adjusting ring 73. When the locking cam 73 is unlocked, the locking cam 71 is unlocked and the locking cam 72 is unlocked, so that the master lock 7 is unlocked, and the master lock 7 is unlocked, so that the master lock 7 is unlocked.
