Description
Technical Field
[0001] The utility model relates to the technical field of earthquake-resistant dampers, in particular to a support damper used for epicenter bending energy dissipation. Background Art
[0002] In the application of bending energy dissipation at the epicenter, the damper plays a key role as an important energy dissipation element. The metal bending seismic damper is a typical device that uses the bending deformation of metal rods under earthquakes to dissipate the vibration energy of buildings. This damper has the advantages of compact structure and easy installation, and is suitable for some construction projects with high space requirements. It can effectively absorb and consume the energy generated by the vibration of the building, reduce the vibration amplitude of the building, and thus protect the building from earthquake damage.
[0003] However, conventional dampers for epicentral bending energy dissipation also have certain problems. For example, in areas with frequent earthquakes, there are more small earthquakes. The frequent vibrations of small earthquakes can cause buildings to shake but are not enough to pose a structural threat. However, the frequent small vibrations can cause the damper to begin to deform slightly. Under repeated effects, the damper will not be able to play its maximum role when a real large earthquake occurs. In order to solve this technical problem, the utility model proposes a support damper for epicentral bending energy dissipation. Utility Model Content
[0004] The main purpose of the utility model is to provide a support damper used for epicenter bending energy dissipation, which can effectively solve the problems mentioned in the background technology.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A support damper used for epicenter bending energy dissipation includes a top plate, a load-bearing column is arranged below the top plate, damper 1 is installed inside the load-bearing column, damper 2 and damper 3 are arranged below the top plate, a load-bearing rod is fixedly installed on the bottom surface of the top plate, the outer surface of the load-bearing rod is slidably connected to the inner wall of the load-bearing column, and a load-bearing block is fixedly installed on the bottom end of the load-bearing rod.
[0007] Preferably, a fixing plate 1 is fixedly mounted on the bottom surface of the top plate, the bottom surface of the fixing plate 1 is fixedly mounted to the top end of the load-bearing rod, and a fixing plate 2 is fixedly mounted on the outer surface of the load-bearing column.
[0008] Preferably, a support seat 1 is fixedly installed on the outer surface of the fixing plate 1, and a connecting seat 1 is fixedly installed on the outer surface of the fixing plate 2. The outer surface of the support seat 1 is rotatably connected to the outer surface of the damper 2, and the outer surface of the damper 2 is rotatably connected to the outer surface of the connecting seat 1.
[0009] Preferably, the outer surface of the load-bearing column located below the fixed plate two is fixedly installed with a base plate, the outer surface of the base plate is fixedly installed with a support seat two, the outer surface of the fixed plate one is fixedly installed with a connecting seat two, the outer surface of the support seat two is rotatably connected to the outer surface of the damper three, and the outer surface of the damper three is rotatably connected to the outer surface of the connecting seat two.
[0010] Preferably, a spring shock absorber is fixedly mounted on the bottom end of the load-bearing column, a reinforcement rod is fixedly mounted on the outer surface of the spring shock absorber, and the top end of the reinforcement rod is fixedly mounted on the bottom surface of the base plate.
[0011] Preferably, two groups of expansion plates are fixedly installed on the outer surface of the load-bearing column, and the number of expansion plates in each group is four, wherein the outer surface of one group of expansion plates is fixedly installed on the bottom surface of the base plate, and the outer surface of the other group of expansion plates is fixedly installed on the bottom surface of fixed plate 2.
[0012] Preferably, a protective sleeve is fixedly mounted on the bottom surface of the top plate, a protective shell is slidably connected to the outer surface of the protective sleeve, and the inner surface of the protective shell is fixedly mounted to the outer surface of the spring shock absorber.
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] In the utility model, through the cooperation between the top plate, the load-bearing column, the load-bearing rod, the damper 1, the damper 2, the damper 3 and the load-bearing block, the top plate and the load-bearing column are pressed against the building structure. When the building starts to shake slightly, the shaking force transmitted to the top plate and the load-bearing column will be weakened. The fixed connection area between the outer surface of the load-bearing block and the inner wall of the load-bearing column is limited, and the two are connected by simple mortar. When a big earthquake comes, the load-bearing beam or ceiling above the top plate cracks and falls downward, hitting the top plate. At this time, the large impact force will break the connection between the load-bearing block and the load-bearing column, so that the top plate will fall. The top plate moves downward, forcing the load-bearing rod to slide downward inside the load-bearing column, so that damper 1 serves as the main up and down shock absorbing device. While the top plate moves downward, damper 2 and damper 3 deform from their initial horizontal parallel positions to cross-over positions. Before damper 2 and damper 3 are deformed to fully tilt to the maximum angle, the downward movement speed of the top plate can be slowed down. The damage to damper 1 caused by the excessively fast downward movement of the top plate and the load-bearing rod can also be reduced. This solves the problem that conventional dampers cannot play the maximum role originally tested during large earthquakes after experiencing frequent small earthquakes.
[0015] In the utility model, through the cooperation between the protective shell, the top plate and the protective sleeve, the protective sleeve and the protective shell can play a protective role when the equipment is in standby and working states. When the top plate moves downward, it can drive the protective sleeve to move downward. The cooperation with the protective shell can reduce the deformation and make the equipment more practical.

DETAILED DESCRIPTION
[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0023] like Figure 1-5As shown, a support damper used for epicenter bending energy dissipation includes a top plate 1, a load-bearing column 2 is arranged below the top plate 1, a damper 1 3 is installed inside the load-bearing column 2, a damper 2 4 and a damper 3 5 are arranged below the top plate 1, a load-bearing rod 6 is fixedly installed on the bottom surface of the top plate 1, the outer surface of the load-bearing rod 6 is slidably connected to the inner wall of the load-bearing column 2, a load-bearing block 7 is fixedly installed on the bottom end of the load-bearing rod 6, the top plate 1 and the load-bearing column 2 are against the building structure, when the building starts to shake slightly, the shaking force transmitted to the top plate 1 and the load-bearing column 2 will be weakened, the outer surface of the load-bearing block 7 and the inner wall of the load-bearing column 2 are fixedly connected in an area limited, and the two are connected by simple mortar, when a strong earthquake comes, the load-bearing beam or ceiling above the top plate 1 will crack and fall down When it falls, it will hit the top plate 1. At this time, the greater impact force will break the connection between the load-bearing block 7 and the load-bearing column 2, so that the top plate 1 moves downward, forcing the load-bearing rod 6 to slide downward inside the load-bearing column 2, so that the damper 1 3 serves as the main up and down shock absorbing device. When the top plate 1 moves downward, the damper 2 4 and the damper 3 5 are deformed from the initial horizontal parallel to each other to cross each other. Before the damper 2 4 and the damper 3 5 are deformed to fully tilted to the maximum angle, the downward movement speed of the top plate 1 can be slowed down, and the damage to the damper 1 3 caused by the excessive downward movement speed of the top plate 1 and the load-bearing rod 6 can be reduced. This solves the problem that conventional dampers cannot play the maximum role originally tested during large earthquakes after experiencing frequent small earthquakes.
[0024] A fixing plate 8 is fixedly installed on the bottom surface of the top plate 1, and the bottom surface of the fixing plate 8 and the top end of the load-bearing rod 6 are fixedly installed. A fixing plate 2 9 is fixedly installed on the outer surface of the load-bearing column 2. The load-bearing rod 6 can provide support for the fixing plate 8 and the top plate 1, and the load-bearing column 2 can provide support for the fixing plate 2 9. When the top plate 1 falls downward, since the load-bearing column 2 is fixed, the fixing plate 8 will be moved closer to the fixing plate 2 9.
[0025] A support seat 10 is fixedly installed on the outer surface of the fixing plate 18, and a connecting seat 11 is fixedly installed on the outer surface of the fixing plate 29. The outer surface of the support seat 10 is rotatably connected to the outer surface of the damper 24, and the outer surface of the damper 24 is rotatably connected to the outer surface of the connecting seat 11. When the fixing plate 18 moves downward, the damper 24 can be driven to move through the support seat 10. Since the fixing plate 29 is in a fixed position, the damper 24 is in a tilted state.
[0026] The outer surface of the load-bearing column 2 located below the fixed plate 2 9 is fixedly installed with a base plate 12, the outer surface of the base plate 12 is fixedly installed with a support seat 2 13, the outer surface of the fixed plate 1 8 is fixedly installed with a connecting seat 2 14, the outer surface of the support seat 2 13 is rotatably connected to the outer surface of the damper 3 5, the outer surface of the damper 3 5 is rotatably connected to the outer surface of the connecting seat 2 14, when the fixed plate 1 8 moves downward, it can drive the connecting seat 2 14 to move downward, because the position of the base plate 12 and the load-bearing column 2 does not change, it will drive the damper 3 5 to start tilting, and the tilt directions of the damper 3 5 and the damper 2 4 are opposite to each other, so it can resist and buffer the impact of any tilt angle from top to bottom.
[0027] A spring shock absorber 15 is fixedly installed at the bottom end of the load-bearing column 2, and a reinforcement rod 16 is fixedly installed on the outer surface of the spring shock absorber 15. The top of the reinforcement rod 16 is fixedly installed to the bottom surface of the base plate 12. A viscous damper is also installed inside the spring shock absorber 15. As the main load-bearing and overall buffer during small and large earthquakes, the reinforcement rod 16 can share part of the load-bearing force for the load-bearing column 2, thereby reducing the overall pressure on the load-bearing column 2.
[0028] Two groups of expansion plates 17 are fixedly installed on the outer surface of the load-bearing column 2, and the number of expansion plates 17 in each group is four. The outer surface of one group of expansion plates 17 is fixedly installed on the bottom surface of the base plate 12, and the outer surface of the other group of expansion plates 17 is fixedly installed on the bottom surface of the fixed plate 29. The expansion plates 17 can increase the contact area between the base plate 12, the fixed plate 29 and the load-bearing column 2, so that the base plate 12 and the fixed plate 29 can be more tightly fixed on the outer surface of the load-bearing column 2.
[0029] A sheath 18 is fixedly installed on the bottom surface of the top plate 1, and a protective shell 19 is slidably connected to the outer surface of the sheath 18. The inner surface of the protective shell 19 and the outer surface of the spring shock absorber 15 are fixedly installed. The sheath 18 and the protective shell 19 can play a protective role when the equipment is in standby and working states. When the top plate 1 moves downward, it can drive the sheath 18 to move downward, and cooperate with the protective shell 19 to reduce deformation, making the equipment more practical.
