Description

Technical Field

[0001] This invention belongs to the field of building vibration reduction technology, and in particular relates to a structural vibration reduction control system suitable for densely built areas. Background Technology

[0002] With economic development and the diversification of social needs, buildings are becoming increasingly tall and complex in form, and architectural designs are pursuing multifunctional, versatile spaces and rich facade effects. Therefore, seismic design in densely built-up areas has become a key focus.

[0003] In the field of seismic resistance of buildings, the main way to improve the seismic performance of building structures is to increase the rigidity of the building structure and its resistance to lateral displacement. While this method increases the structure's own resistance, it may also increase its fundamental frequency, which may increase the seismic force to some extent. Therefore, only by choosing a reasonable seismic damping and strengthening method can the seismic damping performance of the building structure itself be effectively improved.

[0004] The existing seismic control systems in densely built-up areas all connect multiple buildings into one unit using prefabricated panels. However, due to the large span of the buildings, the construction is quite troublesome and also increases the connection cost. Summary of the Invention

[0005] In view of this, in order to solve the problem that the existing vibration reduction control system in densely built areas connects multiple buildings into one unit by prefabricated assembly panels, but due to the large span of the buildings, the construction is complicated and the connection cost is increased, the present invention provides a structural vibration reduction control system suitable for densely built areas.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A structural vibration reduction and control system suitable for densely built areas includes four buildings. A rubber pad is provided between two adjacent buildings on the left and right. The top of the rubber pad has a groove, and a semi-circular block is provided in the groove. A vibration reduction box is provided on the top of the semi-circular block, and a vibration reduction mechanism is provided in the vibration reduction box. A first reinforcing plate is fixed on the side of the two buildings that are close to each other. The bottom end of the first reinforcing plate is connected to the vibration reduction mechanism for vibration reduction of the two buildings on the left and right.

[0008] The four buildings are arranged in a grid pattern, with multiple damping connectors fixed on their adjacent sides to connect the four buildings into a whole, forming a group of vibration damping systems.

[0009] Furthermore, the shock absorption mechanism includes two sets of first rotating seats fixedly connected to the top of the shock absorption box. A second rotating shaft is fixedly provided through the bottom of the first reinforcing plate. The second rotating shaft is rotatably connected between two adjacent first rotating seats. A rotating plate is fixedly sleeved on the outer wall of the second rotating shaft. A third rotating shaft is fixedly provided on one side of the rotating plate. The same connecting plate is rotatably sleeved on the outer walls of the two third rotating shafts.

[0010] Furthermore, a first rotating shaft is fixedly installed through one side of the top of the first reinforcing plate, and the outer walls of the two first rotating shafts are rotatably fitted with the same connecting frame.

[0011] Furthermore, a fixed seat is fixedly installed on one inner wall of the shock absorber box, and a hydraulic cylinder is fixedly installed through one side of the fixed seat. A piston rod is slidably installed through one side of the hydraulic cylinder. Both ends of the piston rod are provided with baffles, and a connecting plate is located between the two baffles. A piston ring located inside the hydraulic cylinder is fixedly sleeved on the outer wall of the piston rod. The piston ring divides the inside of the hydraulic cylinder into two receiving cavities for holding hydraulic oil.

[0012] Furthermore, two springs are fitted on the outer wall of the piston rod, with the two ends of the springs fixedly connected to the piston ring and the adjacent side of the receiving cavity, respectively.

[0013] Furthermore, the cylinder has oil passages that communicate with the two receiving cavities.

[0014] Furthermore, the damping connector includes a second reinforcing plate fixedly connected to one side of the building. Two fixing blocks are fixedly provided on one side of the second reinforcing plate, and two second dampers are rotatably provided on one side of the second reinforcing plate. A first damper is rotatably provided on one side of the fixing blocks. The output ends of the corresponding four second dampers and the first dampers are all rotatably provided with the same connecting block.

[0015] Furthermore, a second rotating seat corresponding to the second damper and the first damper is fixedly provided on one side of the second reinforcing plate and the fixing block, respectively. The second rotating seat is rotatably connected to the corresponding first damper and the second damper through the fourth rotating shaft. A third rotating seat corresponding to the second damper and the first damper is fixedly provided on one side of the connecting block, respectively. The third rotating seat is rotatably connected to the corresponding first damper and the second damper through the fifth rotating shaft.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. The present invention discloses a structural vibration reduction control system suitable for densely built areas. When one of the buildings shakes, the first and second dampers are compressed by the second reinforcing plate and the connecting block to buffer and reduce vibration. When the shaking amplitude is large, it will cause the buildings in the other damping boxes to shake together, so that they form a whole and reduce the vibration force. By setting the damping connector, the four adjacent buildings can be connected together to achieve the effect of simultaneous force.

[0018] 2. The structural vibration reduction control system disclosed in this invention, applicable to densely built-up areas, utilizes a buffer mechanism. When a building tilts, it causes the first reinforcing plate to tilt. The tilting and rotation of the first reinforcing plate causes the second rotating shaft to rotate, which in turn causes a rotating plate to rotate. The rotating plate, through a connecting plate, causes another first reinforcing plate to rotate, resulting in two adjacent buildings being subjected to force simultaneously. When the connecting plate moves, it can cause the piston rod to move within the cylinder via a baffle, squeezing the hydraulic oil in the receiving cavity into the oil passage and then into another receiving cavity, thus slowing down the moving speed of the connecting plate. Simultaneously, it compresses the spring, causing the two adjacent first reinforcing plates to rotate simultaneously, facilitating the simultaneous tilting of two adjacent buildings and further improving the vibration reduction effect.

[0019] 3. The structural vibration reduction control system disclosed in this invention, applicable to densely built areas, allows two adjacent buildings to be subjected to force simultaneously through the combined use of a first reinforcing plate and a piston rod, thus achieving a certain vibration reduction effect. Furthermore, by connecting four adjacent buildings together through a damping connector, the vibration reduction and buffering effect is further improved, and the system is easy to install.

[0033] Example 1

[0034] Reference Figure 1-7 A structural vibration reduction control system suitable for densely built areas is applied in the field of building vibration reduction technology. Among four buildings 1, a rubber pad 2 is provided between two adjacent buildings 1 on the left and right. The top of the rubber pad 2 has a groove 18, and a semi-circular block 17 is provided in the groove 18. The top of the semi-circular block 17 is provided with a vibration reduction box 3, and a vibration reduction mechanism is provided in the vibration reduction box 3. A first reinforcing plate 6 is fixed on one side of the two buildings 1 that are close to each other. The bottom end of the first reinforcing plate 6 is connected to the vibration reduction mechanism to reduce the vibration of the two buildings 1 on the left and right.

[0035] Four buildings 1 are arranged in a grid pattern, with multiple damping connectors 5 fixed on one side of each other to connect the four buildings 1 into a whole and form a group of vibration reduction. By setting vibration reduction mechanisms between two adjacent buildings 1 and connecting the four buildings 1 with multiple damping connectors 5, they are formed into a whole and can perform group vibration reduction, making them more robust.

[0036] The shock absorption mechanism includes two sets of first rotating seats 8 fixedly connected to the top of the shock absorption box 3. A second rotating shaft 9 is fixedly provided through the bottom of the first reinforcing plate 6. The second rotating shaft 9 is rotatably connected between two adjacent first rotating seats 8. A rotating plate 10 is fixedly sleeved on the outer wall of the second rotating shaft 9. A third rotating shaft 11 is fixedly provided on one side of the rotating plate 10. The same connecting plate 12 is rotatably sleeved on the outer walls of the two third rotating shafts 11. By setting the rotating plate 10 and the connecting plate 12, when one of the first reinforcing plates 6 tilts and rotates around the first rotating seat 8, it can drive the other first reinforcing plate 6 to rotate, so that they tilt synchronously.

[0037] A fixed seat 13 is fixedly installed on one inner wall of the shock absorber box 3. A hydraulic cylinder 14 is fixedly installed through one side of the fixed seat 13. A piston rod 15 is slidably installed through one side of the hydraulic cylinder 14. Both ends of the piston rod 15 are provided with baffles 16. A connecting plate 12 is located between the two baffles 16. A piston ring 19 located inside the hydraulic cylinder 14 is fixedly sleeved on the outer wall of the piston rod 15. The piston ring 19 divides the hydraulic cylinder 14 into two receiving cavities 20 for holding hydraulic oil. When the connecting plate 12 moves, it can drive the piston rod 15 to move through the baffles 16, which in turn drives the piston ring 19 to move inside the hydraulic cylinder 14, squeezing the hydraulic oil in the receiving cavity 20, thus achieving a buffering effect.

[0038] The damping connector 5 includes a second reinforcing plate 23 fixedly connected to one side of the building 1. Two fixing blocks 24 are fixedly provided on one side of the second reinforcing plate 23. Two second dampers 31 are rotatably provided on one side of the second reinforcing plate 23. A first damper 26 is rotatably provided on one side of the fixing blocks 24. The output ends of the four corresponding second dampers 31 and first dampers 26 are all rotatably provided with the same connecting block 25. By setting the second dampers 31 and first dampers 26, the four buildings 1 can be connected together so that they can pull against each other and further improve the shock absorption effect.

[0039] A second rotating seat 27 corresponding to the second damper 31 and the first damper 26 is fixedly provided on one side of the second reinforcing plate 23 and the fixing block 24 respectively. The second rotating seat 27 is rotatably connected to the corresponding first damper 26 and the second damper 31 respectively through the fourth rotating shaft 28. A third rotating seat 29 corresponding to the second damper 31 and the first damper 26 is fixedly provided on one side of the connecting block 25 respectively. The third rotating seat 29 is rotatably connected to the corresponding first damper 26 and the second damper 31 respectively through the fifth rotating shaft 30. The setting of the second rotating seat 27 and the third rotating seat 29 can support the first damper 26 and the second damper 31 and allow them to rotate, which is convenient for connection.

[0040] Example 2

[0041] refer to Figure 5 An improvement based on embodiment 1 is made: a first rotating shaft 7 is fixedly installed through one side of the top of the first reinforcing plate 6, and the same connecting frame 4 is rotatably sleeved on the outer wall of the two first rotating shafts 7. The connecting frame 4 can be used to further fix the connection between two adjacent buildings 1.

[0042] Two springs 21 are fitted on the outer wall of the piston rod 15. The two ends of the springs 21 are fixedly connected to the piston ring 19 and the receiving cavity 20 respectively on the side that are close to each other. The setting of the two springs 21 can make the piston rod 15 automatically return to its original position after it moves.

[0043] The cylinder 14 has an oil passage 22 that communicates with the two receiving cavities 20. The oil passage 22 allows the hydraulic oil in the receiving cavity 20 to be squeezed into the other receiving cavity 20, thereby reducing the oil pressure and preventing the cylinder 14 from breaking.

[0044] This structural vibration control system, applicable to densely built areas, compresses the first damper 26 and the second damper 31 through the second reinforcing plate 23 and the connecting block 25 when one of the buildings 1 shakes, thus buffering and reducing vibration. When the shaking amplitude is large, it will cause the buildings 1 in the other damping boxes 3 to shake together, making them form a whole and reducing the vibration intensity.

[0045] Simultaneously, building 1 will cause the shock absorber box 3 to tilt and rotate on the rubber pad 2 via the first reinforcing plate 6. When building 1 tilts, it will cause the first reinforcing plate 6 to tilt. When the first reinforcing plate 6 tilts and rotates, it can drive the second rotating shaft 9 to rotate. The second rotating shaft 9 drives the rotating plate 10 to rotate. The rotating plate 10 drives another first reinforcing plate 6 to rotate via the connecting plate 12, so that the two adjacent buildings 1 are subjected to force at the same time. When the connecting plate 12 moves, it can drive the piston rod 15 to move in the oil cylinder 14 via the baffle 16, squeezing the hydraulic oil in the receiving cavity 20 into the oil passage 22 and then into another receiving cavity 20, so as to slow down the moving speed of the connecting plate 12 and squeeze the spring 21 for further buffering.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
