Abstract
Description
Technical Field
[0001] This application belongs to the field of vibration damping technology, and in particular relates to a vibration damping connector used in steel structure buildings. Background Technology
[0002] A vibration damper is a specialized device that reduces structural vibration and protects the safety of steel structure buildings by actively dissipating external energy. It is a core component in the seismic and wind-resistant design of engineering projects.
[0003] According to utility model application number CN220167217U, a viscous damper for building vibration reduction is disclosed, including a cylinder body, a piston rod slidably connected inside the cylinder body, the end of the piston rod extending outside the cylinder body, a connecting seat provided on both sides of the cylinder body, a groove provided on the outer side of the connecting seat, and the inner walls on both sides of the groove being set as openings, and two vertical blocks fixedly connected to the outer side of the connecting seat.
[0004] The above technical solution involves a screw driving a rectangular block to move, which in turn drives a horizontal seat to move via a connecting plate. The horizontal seat moves away from the connecting plate and is then fixed in the gaps of the structural beams by bolts. This allows the height of the viscous damper to be adjusted during installation, adapting to structural beams with different spacing. This method is highly practical and has a positive impact on building vibration reduction. However, in this technical solution, the damper is installed between steel structures using bolts. These bolts are prone to loosening under vibration, requiring workers to periodically check their tightness, which is inconvenient.
[0005] To address this issue, we propose a shock-absorbing and damping connector for use in steel structure buildings. Utility Model Content
[0006] The purpose of this application is to solve the problem in the prior art that it is impossible to automatically check the condition of the damper bolt connection, and to propose a shock-absorbing damping connector for use in steel structure buildings.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A damping connector for use in steel structure buildings includes a damper body. Two rectangular plates are fixedly connected to the outer surface of the damper body. Three sets of bolts are threaded onto the inner wall of each rectangular plate. Two sliding cylinders are slidably connected to the inner wall of each rectangular plate. A rotating shaft is rotatably connected to the inner wall of each sliding cylinder. A flip plate is fixedly connected to the outer surface of each rotating shaft. Three threaded cylinders are rotatably connected to the inner wall of each flip plate. A threaded shaft is threaded into the interior of each threaded cylinder. The end of each threaded shaft near the bolt is fixed. Each of the flip plates is connected with a locking block. A positioning plate is provided on the side away from the rectangular plate. Three return springs are fixedly connected to the inner top wall of each positioning plate. A circular plate is fixedly connected to the end of each return spring near the threaded shaft. A bullseye bearing is fixedly connected to the side of each circular plate near the threaded shaft. The outer surface of each bullseye bearing is in contact with the side of the threaded shaft near the circular plate. A warning shaft is fixedly connected to the end of each circular plate away from the threaded shaft. The end of each warning shaft away from the circular plate passes through the positioning plate and extends to the outside of the positioning plate.
[0009] Preferably, each of the two rectangular plates has a fixing block fixedly connected to one side of each other, and the number of bolts in each group is two.
[0010] Preferably, the inner wall of each of the fixed blocks is rotatably connected to a limiting shaft, and the end of each limiting shaft away from the rectangular plate is fixedly connected to a limiting plate. The side of each limiting plate near the flipping plate is in contact with the side of the flipping plate near the limiting plate.
[0011] Preferably, each of the positioning plates has two support columns fixedly connected to one side of the flip plate, and one end of each support column is fixedly connected to the side of the flip plate near the positioning plate.
[0012] Preferably, rubber pads are fixedly connected to the opposite sides of the two rectangular plates, and the outer surface of each of the locking blocks is engaged with the inside of the bolt.
[0013] Preferably, each of the circular plates has a positioning shaft fixedly connected to the side away from the threaded shaft, and the outer surface of each positioning shaft is slidably connected to the inside of the positioning plate.
[0014] In summary, the technical effects and advantages of this application are as follows:
[0015] By incorporating a locking block that engages with the bolt, when the bolt vibrates and rotates, the locking block rotates synchronously. This rotation transmits power to the threaded shaft, causing it to rotate as well. The threaded shaft, through its threaded connection with the threaded cylinder, moves the locking block upwards. This upward movement of the threaded shaft also pushes the bullseye bearing upwards. The bullseye bearing counteracts the rotational force transmitted from the threaded shaft, retaining the thrust necessary to move it. This allows the circular plate and warning shaft to move, protruding the warning shaft to the outside of the positioning plate. Therefore, workers only need to periodically check if the warning shaft is protruding; there is no need to use equipment to test for bolt looseness. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Reference Figure 1-5A shock-absorbing damping connector used in steel structure buildings includes a shock-absorbing damper body 1. Two rectangular plates 7 are fixedly connected to the outer surface of the shock-absorbing damper body 1. Three sets of bolts 6 are threadedly connected to the inner wall of each rectangular plate 7. Fixing blocks 11 are fixedly connected to the side of the two rectangular plates 7 that are close to each other. There are two bolts 6 in each set. By setting the fixing blocks 11, the fixing blocks 11 can provide an installation position for the limiting structure.
[0024] Each rectangular plate 7 has two sliding cylinders 15 slidably connected to its inner wall. Each sliding cylinder 15 has a rotating shaft 14 rotatably connected to its inner wall. Each rotating shaft 14 has a flip plate 4 fixedly connected to its outer surface. Each fixed block 11 has a limiting shaft 12 rotatably connected to its inner wall. Each limiting shaft 12 has a limiting plate 13 fixedly connected to its end away from the rectangular plate 7. The side of each limiting plate 13 near the flip plate 4 is in contact with the side of the flip plate 4 near the limiting plate 13. By setting the limiting shaft 12, the limiting shaft 12 can drive the limiting plate 13 to rotate, so that the limiting plate 13 rotates to one side of the flip plate 4, thereby providing a limit for the flip plate 4.
[0025] Each flip plate 4 has three threaded cylinders 8 rotatably connected to its inner wall. Each threaded cylinder 8 has a threaded shaft 17 threaded inside. Each threaded shaft 17 has a locking block 16 fixedly connected to the end near the bolt 6. Each flip plate 4 has a positioning plate 2 on the side away from the rectangular plate 7. Each positioning plate 2 has three return springs 20 fixedly connected to its inner top wall. Each return spring 20 has a circular plate 19 fixedly connected to the end near the threaded shaft 17. Each circular plate 19 has a bullseye bearing 18 fixedly connected to the side near the threaded shaft 17. The outer surface of each bullseye bearing 18 is in contact with the side of the threaded shaft 17 near the circular plate 19. Each positioning plate 2 has two support columns 9 fixedly connected to the side near the flip plate 4. Each support column 9 has one end fixedly connected to the side of the flip plate 4 near the positioning plate 2. By setting up the support columns 9, the positioning plate 2 can be provided with support force.
[0026] Each circular plate 19 is fixedly connected to a warning shaft 3 at the end away from the threaded shaft 17. The two rectangular plates 7 are fixedly connected to rubber pads 5 on their opposite sides. The outer surface of each locking block 16 is locked into the inside of the bolt 6. By setting the rubber pads 5, the high friction coefficient of the rubber pads 5 can make the connection between the rectangular plates 7 and the steel structure more stable.
[0027] Each warning shaft 3 has one end away from the circular plate 19 that passes through the positioning plate 2 and extends to the outside of the positioning plate 2. Each circular plate 19 has a positioning shaft 10 fixedly connected to one side away from the threaded shaft 17. The outer surface of each positioning shaft 10 is slidably connected to the inside of the positioning plate 2. By setting the positioning shaft 10, the circular plate 19 can be positioned so that the circular plate 19 can only move up and down.
[0028] The working principle of this utility model is as follows: When the bolt 6 is subjected to vibration and rotates, the rotation of the bolt 6 will cause the internally engaged locking block 16 to rotate together, thereby causing the locking block 16 and the threaded shaft 17 to rotate synchronously. When the threaded shaft 17 rotates, the threaded connection between the threaded shaft 17 and the threaded cylinder 8 can drive the threaded shaft 17 to move towards the bullseye bearing 18. Note that when the threaded shaft 17 moves towards the bullseye bearing 18, the locking block 16 fixed at one end of the threaded shaft 17 will also move synchronously. The threaded shaft 17 will transmit the rotational power and the vertical thrust to the bullseye bearing 18 together. However, the bullseye bearing 18 will rotate to cancel out the rotational power, retaining only the vertical thrust, thereby pushing the bullseye bearing. 18. The circular plate 19 and the warning shaft 3 squeeze the return spring 20, eventually exposing the warning shaft 3 to the outside of the positioning plate 2. Therefore, the staff only needs to periodically observe whether the warning shaft 3 is exposed to the outside of the positioning plate 2 to determine whether the bolt 6 is loose. When it is necessary to manually remove the damper body 1, the limiting plate 13 can be rotated. The limiting plate 13 will drive the limiting shaft 12 to rotate until the limiting plate 13 rotates to a position where it does not contact the flip plate 4. Then, the sliding cylinder 15 is pulled to move, so that the sliding cylinder 15 drives the flip plate 4 and the locking block 16 to move vertically until the locking block 16 is disengaged from the bolt 6. Then the sliding cylinder 15 can be removed. After that, the bolt 6 can be removed using tools.
