Description

Technical Field

[0001] The invention relates to the technical field of building structure vibration control, in particular to an adaptive building structure vibration control device and an adjustment method thereof. Background Art

[0002] For large high-rise buildings, vibration reduction mechanisms are usually added to the building structure in order to improve the earthquake resistance of the entire structure. Existing vibration reduction mechanisms usually use tuned mass dampers to reduce vibrations of building structures. However, when dealing with lateral vibrations of building components, the existing tuned mass dampers have poor resistance and energy dissipation effects, so their lateral vibration reduction effects on building components are also poor. When building components encounter torsional vibrations, since the mass block in the existing tuned mass damper is also subjected to lateral vibrations, the mass is not in the center of the entire vibration reduction mechanism, which will cause the anti-torsion characteristics to deteriorate and increase the degree of torsion of the building components.

[0003] An existing patent (publication number: CN110644639B) discloses a vibration-absorbing device applied to a building structure and a method of using the same, comprising a hanger, a base plate and a mass block. The hanger is fixed to the top of the building structure and is connected to the mass block through a spring. The base plate is fixed to the building structure. A plurality of damping mechanisms 1 are hingedly connected to the side wall of the mass block. The lower end of the damping mechanism 1 is hingedly connected to the building structure. Each of the damping mechanisms 1 is connected to a damping mechanism 2 through a hydraulic pipe. The damping mechanism 2 is fixed to the building structure. A counterweight block is arranged on the base plate. The counterweight block can be connected to the mass block through a return mechanism. The counterweight block can be connected to the damping mechanism 2. The vibration-absorbing device applied to the building structure and a method of using the same can adaptively adjust the energy consumption according to the magnitude of the vibration, and can promote the mass block to return as soon as possible, thereby improving the seismic performance of the building structure and improving the service life and safety of the building structure.

[0004] However, the above technical solution still has certain defects. During use, the damping mechanism is directly connected to the building body, while the vibration amplitude of the building is limited and the sliding distance of the piston inside the damping mechanism is small, so that the damping effect cannot be fully utilized.

[0034] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0035] The following describes an embodiment of the present invention based on its overall structure.

[0036] Adaptive building structure vibration control device, such as Figures 1 to 6As shown, it includes an outer frame 1, and the outer frame 1 includes a bottom plate 101, and two groups of side frames 102 are fixedly connected to the bottom end of the bottom plate 101, and two groups of rotating arms 103 are rotatably connected between the two groups of side frames 102, and the bottom ends of the two groups of rotating arms 103 are fixedly connected to sliding rods 106, and the outer wall of the sliding rod 106 is slidably sleeved with a sliding bar, and the sliding bar is provided with a first sliding groove 108 at the contact position with the sliding rod 106, and the top of the bottom plate 101 is fixedly connected with two groups of guide rods 109, and the two groups of sliding heads 107 are respectively slidably sleeved on the outer wall of a group of guide rods 109, and the tops of the two groups of rotating arms 103 are respectively rotatably connected with a group of connecting rods 104, and the tops of the two groups of connecting rods 104 are hinged with top plates 105;

[0037] An adjustment mechanism 2 is provided at the top of the base plate 101, and the adjustment mechanism 2 includes two groups of magnetic strips 201, and the two groups of magnetic strips 201 are respectively fixedly connected to the end of a group of sliding heads 107. Two groups of brackets 202 are fixedly connected to the top of the base plate 101, and the two groups of brackets 202 are respectively sleeved on the outside of the two groups of magnetic strips 201, and the outer wall of the bracket 202 is sleeved with a coil 203.

[0038] When the building structure is vibrated, the top plate 105 and the bottom plate 101 are vibrated and pushed, so that the top plate 105 pushes the rotating arm 103 to flip through the connecting rod 104, and in the process of the rotating arm 103 rotating between the two sets of side frames 102, the rotating arm 103 forms a force lever structure, so that after being vibrated, the movement of the top rod 303 drives the sliding rod 106 to flip through the rear of the rotating arm 103, so that the flipping range of the sliding rod 106 is larger, so that the piston 302 can slide inside the sleeve rod to a larger extent, so that the shock absorption effect is more sufficient During the flipping process of the slide rod 106, it slides inside the first slide groove 108, thereby pushing the sliding head 107 to slide on the outer wall of the guide rod 109, so that the sliding head 107 can drive the shock absorbing mechanism 3 to operate. During the movement of the sliding head 107, it drives the magnetic strip 201 to move, so that the magnetic strip 201 continuously moves inside the bracket 202, so that the coil 203 outside the bracket 202 continuously cuts the magnetic flux lines to generate current, and the existing control device controls the motor 210 to rotate after detecting the current, thereby driving the adjustment mechanism 2 to operate.

[0039] Please refer to Figures 2 to 5A group of shock absorbing mechanisms 3 are fixedly connected to the top of the bottom plate 101 at both ends, and the shock absorbing mechanism 3 includes a sleeve 301, the inner wall of the sleeve 301 is provided with damping oil, the inner wall of the sleeve 301 is slidably sleeved with a piston 302, the side wall of the piston 302 is fixedly connected with a push rod 303, the inner wall of the push rod 303 is rotatably connected with an adjusting rod 306, the end of the adjusting rod 306 located inside the sleeve 301 is fixedly connected with an adjusting plate 305, the side wall of the piston 302 is penetrated with a first through hole 307, the side wall of the adjusting plate 305 is penetrated with a second through hole 308, the outer wall of the push rod 303 extends to the outside of the sleeve 301, and the end of the push rod 303 located outside the sleeve 301 is fixedly connected with a fixing seat 30 4. The fixed seat 304 is fixedly connected to the side wall of the sliding head 107, and the end of the adjusting rod 306 extending to the outside of the top rod 303 is fixedly connected to the rotating rod 204. The end of the rotating rod 204 is provided with a second sliding groove 205, and the inner wall of the second sliding groove 205 is slidably sleeved with a connecting head 206. The side wall of the connecting head 206 is fixedly connected with a push rod 207, and the push rod 207 is slidably connected to the inner wall of the fixed seat 304. The side wall of the push rod 207 is fixedly connected with multiple groups of bevel teeth 208. The side wall of the fixed seat 304 is rotatably connected with a worm 209, and the worm 209 is meshed with the bevel teeth 208. The side wall of the fixed seat 304 is fixedly connected with a motor 210, and the output end of the motor 210 is connected to the end of the worm 209 through a gear set.

[0040] The existing control device drives the motor 210, so that the motor 210 drives the worm 209 to rotate, and the worm 209 pushes the helical gear 208 to push the push rod, and the push rod pushes the connecting head 206 in the process of sliding on the inner wall of the connecting seat, so that the connecting head 206 pushes the rotating rod 204 to flip and slide inside the second sliding groove 205, and the rotating rod 204 drives the adjusting rod 306 to rotate in the process of flipping, so that the adjusting rod 306 drives the adjusting plate 305 to rotate, thereby driving the second through hole 308 to rotate, so as to adjust the second through hole 308 to coincide with the first through hole 307, so that the damping oil is smoother in the process of passing through the first through hole 307 and the second through hole 308, thereby reducing the damping effect, and the rotating rod 204 reverses. The movement can reduce the overlap between the first through hole 307 and the second through hole 308, so that the damping oil encounters greater resistance when passing through the first through hole 307 and the second through hole 308, thereby enhancing the damping effect. When the building structure vibrates, the sliding head 107 pushes the connecting seat, so that the connecting seat pushes the push rod 303, thereby pushing the piston 302 to slide on the inner wall of the sleeve 301, so that the damping oil inside the sleeve 301 passes through the first through hole 307 and the second through hole 308. In the process of the damping oil passing through the first through hole 307 and the second through hole 308, since the damping oil is relatively viscous, the piston 302 needs to overcome a large resistance during the sliding process, thereby consuming the vibration and playing a shock-absorbing role.

[0041] When using, the usage is as follows:

[0042] 1. Fixing method:

[0043] The top plate 105 is fixed to the ceiling by bolts, or fixed to the bottom end of the upper beam of the building frame, and the bottom plate 101 is placed on the top of the bottom plate 101, so that the device fits tightly with the ceiling and bottom plate 101 of the building structure;

[0044] 2. Damping strength preset:

[0045] By manually pushing the worm 209 to rotate, the worm 209 drives the bevel teeth 208, thereby rotating the adjustment rod 306, so that the overlap between the first through hole 307 and the second through hole 308 is adjusted, and the initial damping strength is adjusted according to the specific structural characteristics of the building structure. The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology.
