[0028] The three-dimensional vibration isolation support provided by this utility model will now be described.

[0029] Example 1

[0030] Please refer to the following: Figures 1 to 2The three-dimensional vibration isolation support includes a first connecting plate 1, a second connecting plate 2, an elastic damping component 3, and a rubber support 4. The second connecting plate 2 is arranged vertically and horizontally with the first connecting plate 1, and the first connecting plate 1 can slide vertically relative to the second connecting plate 2. The second connecting plate 2 is fixed to the foundation. The elastic damping component 3 is disposed between the first connecting plate 1 and the second connecting plate 2. Under the action of external force, when the first connecting plate 1 slides relative to the second connecting plate 2, the elastic damping component 3 can deform and store energy. When the external force is removed, the elastic damping component 3 releases energy and drives the relative reset of the first connecting plate 1 and the second connecting plate 2. The rubber support 4 is disposed on the top of the first connecting plate 1, and the top of the rubber support 4 is connected to the building to be damped.

[0031] The beneficial effects of the three-dimensional vibration isolation bearing provided in this embodiment are as follows: Compared with the prior art, the three-dimensional vibration isolation bearing provided in this embodiment, through the combined design of elastic damping components and rubber bearings, can effectively buffer the vibration caused by subway operation through the energy storage and release mechanism of the elastic damping components, while the rubber bearing reduces the transmission of seismic shear force through flexible connection, realizing energy dissipation in the x, y, and z directions with the bearing as the coordinate origin, achieving the effect of three-dimensional vibration isolation, significantly improving the seismic performance of the superstructure building and reducing the interference of subway operation on the building.

[0032] like Figure 2 As shown, the rubber bearing 4 includes a first mounting plate 401, a second mounting plate 402, and a rubber vibration isolation layer 403. The first mounting plate 401 is used to connect to the building to be isolated. The second mounting plate 402 is arranged at intervals from the first mounting plate 401, and the first mounting plate 401 and the second mounting plate 402 can slide relative to each other. The second mounting plate 402 is detachably connected to the first connecting plate 1. The rubber vibration isolation layer 403 is disposed between the first mounting plate 401 and the second mounting plate 402. The rubber vibration isolation layer 403 includes multiple layers of rubber sheets 404, steel plates 405, and a protective cover 406. The rubber sheets 404 and steel plates 405 are arranged alternately, and adjacent rubber sheets 404 and steel plates 405 are vulcanized together. The protective cover 406 covers the outside of the rubber sheets 404 and steel plates 405. The structure, which alternately vulcanizes multi-layered 404 rubber sheets and 405 steel plates, provides stable vertical support while allowing for multi-directional horizontal deformation. This not only adapts to the long-term effects of building loads but also disperses subway vibration energy through layered energy dissipation, extending the service life of the supports and reducing vibration transmission efficiency.

[0033] Specifically, in this embodiment, the second mounting plate 402 is provided with multiple first connecting holes, and the first connecting plate 1 is provided with multiple second connecting holes. The first connecting holes and the second connecting holes correspond one-to-one. The first bolts 407 are screwed into the corresponding first connecting holes and second connecting holes to fix the first mounting plate 401 to the first connecting plate 1. The bolt connection method of the first connecting holes and the second connecting holes simplifies the installation and maintenance process of the support, facilitates the adjustment of the support layout or the replacement of damaged parts according to the building load requirements, and improves construction efficiency and economy.

[0034] In this embodiment, the elastic damping component 3 includes multiple leaf springs 301. The leaf springs 301 are evenly arranged along the width direction of the second connecting plate 2. The leaf springs 301 are arched and inverted on the second connecting plate 2. A third connecting hole is provided through the leaf spring 301. The first connecting plate 1 is provided with multiple fourth connecting holes. The third connecting holes and the fourth connecting holes correspond one-to-one. The second bolt 302 is screwed into the corresponding third connecting hole and the fourth connecting hole to fix the leaf spring 301 to the first connecting plate 1. The arched leaf springs 301 are evenly distributed along the width direction, which can disperse the load and avoid local stress concentration. The inverted structure enhances the vertical bearing capacity. At the same time, the coordinated deformation of multiple leaf springs 301 absorbs seismic energy and adapts to large displacement vibration conditions.

[0035] In addition, the top of the second connecting plate 2 is provided with multiple sets of lifting blocks 201. The leaf spring 301 corresponds one-to-one with each set of lifting blocks 201. Each set of lifting blocks 201 includes two blocks. The top of the lifting blocks 201 is higher than the top surface of the second connecting plate 2. The two ends of the leaf spring 301 overlap the lifting blocks 201 of the corresponding set. The lifting blocks 201 lift the two ends of the leaf spring 301 away from the surface of the second connecting plate 2, forming a lever-type elastic support structure, amplifying the deformation of the leaf spring 301 to improve energy storage efficiency, while preventing the leaf spring 301 from sliding and shifting, ensuring vibration isolation stability.

[0036] like Figure 1 As shown, a guide assembly 202 is provided between the first connecting plate 1 and the second connecting plate 2. The guide assembly 202 is used to guide the relative sliding of the first connecting plate 1 and the second connecting plate 2. The guide assembly 202 constrains the relative sliding direction of the first and second connecting plates 2, preventing the support from undergoing horizontal torsion or overturning under complex vibrations, ensuring that the seismic force is transmitted along the design direction, and improving the overall structural reliability.

[0037] Specifically, the guide assembly 202 is provided in four groups, with each group of guide assemblies 202 respectively located on the front, rear, left, and right sides of the elastic damping assembly 3. Each guide assembly 202 includes a first guide block 203 and a second guide block 204. The first guide block 203 is L-shaped. First fixing plates 205 are provided on both sides of the top of the first guide block 203. The first fixing plates 205 are screwed onto the first connecting plate 1 by third bolts 206, and the horizontal portion of the first guide block 203 is located at the bottom end of the vertical portion of the first guide block 203. The second guide block 204 is L-shaped. The bottom end of the second guide block 204 is provided with second fixing plates on both sides. The second fixing plates are fixed to the second connecting plate 2 by fourth bolts. The horizontal part of the second guide block 204 is located at the top of the vertical part of the second guide block 204. The second guide block 204 is located outside the first guide block 203, and the horizontal parts of the first guide block 203 and the second guide block 204 are arranged at intervals in the vertical direction. The top of the horizontal part of the first guide block 203 abuts against the inner surface of the vertical part of the second guide block 204. The top of the horizontal part of the second guide block abuts against the outer surface of the vertical part of the first guide block 203. The L-shaped first guide block 203 and the second guide block 204, through the nesting and cooperation of the horizontal and vertical parts, restrict lateral displacement while allowing free vertical sliding. The dual guiding mechanism avoids jamming problems and adapts to the multi-directional displacement requirements under the coupling of earthquake and vibration.

[0038] Finally, the rubber sheet 404 is made of high-damping rubber. High-damping rubber significantly improves the energy dissipation capacity of the rubber isolation layer 403, especially for high-frequency vibrations generated during subway operation, and can quickly attenuate vibration amplitude.

[0039] Example 2

[0040] Please see Figure 1 and Figure 3 The three-dimensional vibration isolation support includes a first connecting plate 1, a second connecting plate 2, an elastic damping component 3, and a rubber support 4. The second connecting plate 2 is arranged vertically and horizontally with the first connecting plate 1, and the first connecting plate 1 can slide vertically relative to the second connecting plate 2. The second connecting plate 2 is fixed to the foundation. The elastic damping component 3 is disposed between the first connecting plate 1 and the second connecting plate 2. Under the action of external force, when the first connecting plate 1 slides relative to the second connecting plate 2, the elastic damping component 3 can deform and store energy. When the external force is removed, the elastic damping component 3 releases energy and drives the relative reset of the first connecting plate 1 and the second connecting plate 2. The rubber support 4 is disposed on the top of the first connecting plate 1, and the top of the rubber support 4 is connected to the building to be isolated.

[0041] The beneficial effects of the three-dimensional vibration isolation bearing provided in this embodiment are as follows: Compared with the prior art, the three-dimensional vibration isolation bearing provided in this embodiment achieves bidirectional vibration reduction of both horizontal seismic forces and vertical subway vibrations through the combined design of the elastic damping component 3 and the rubber bearing 4. The energy storage-release mechanism of the elastic damping component 3 can effectively buffer the structural vibrations caused by the subway, while the rubber bearing 4 reduces the transmission of seismic forces through flexible connection, significantly improving the seismic performance of the superstructure and reducing the interference of subway operation on the building.

[0042] The rubber bearing 4 includes a first mounting plate 401, a second mounting plate 402, and a rubber vibration isolation layer 403. The first mounting plate 401 is used to connect to the building to be isolated. The second mounting plate 402 is arranged at intervals from the first mounting plate 401, and the first mounting plate 401 and the second mounting plate 402 can slide relative to each other. The second mounting plate 402 is detachably connected to the first connecting plate 1. The rubber vibration isolation layer 403 is disposed between the first mounting plate 401 and the second mounting plate 402. The rubber vibration isolation layer 403 includes multiple layers of rubber sheets 404, steel plates 405, and a protective cover 406. The rubber sheets 404 and steel plates 405 are arranged alternately, and adjacent rubber sheets 404 and steel plates 405 are vulcanized together. The protective cover 406 covers the outside of the rubber sheets 404 and steel plates 405. The structure, which alternately vulcanizes multi-layered 404 rubber sheets and 405 steel plates, provides stable vertical support while allowing for multi-directional horizontal deformation. This not only adapts to the long-term effects of building loads but also disperses subway vibration energy through layered energy dissipation, extending the service life of the supports and reducing vibration transmission efficiency.

The bolt connection method of the first connecting holes and the second connecting holes simplifies the installation and maintenance process of the support, facilitates the adjustment of the support layout or the replacement of damaged parts according to the building load requirements, and improves construction efficiency and economy.

[0044] In this embodiment, the elastic damping component 3 includes multiple leaf springs 301. The leaf springs 301 are evenly arranged along the width direction of the second connecting plate 2.

The first connecting plate 1 is provided with multiple fourth connecting holes. The third connecting holes and the fourth connecting holes correspond one-to-one. The second bolt 302 is screwed into the corresponding third connecting hole and the fourth connecting hole to fix the leaf spring 301 to the first connecting plate 1. The arched leaf springs 301 are evenly distributed along the width direction, which can disperse the load and avoid local stress concentration. The inverted structure enhances the vertical bearing capacity. At the same time, the coordinated deformation of multiple leaf springs 301 absorbs seismic energy and adapts to large displacement vibration conditions.

[0045] In addition, the top of the second connecting plate 2 is provided with multiple sets of lifting blocks 201. The leaf spring 301 corresponds one-to-one with each set of lifting blocks 201. Each set of lifting blocks 201 includes two blocks. The top of the lifting blocks 201 is higher than the top surface of the second connecting plate 2. The two ends of the leaf spring 301 overlap the lifting blocks 201 of the corresponding set. The lifting blocks 201 lift the two ends of the leaf spring 301 away from the surface of the second connecting plate 2, forming a lever-type elastic support structure, amplifying the deformation of the leaf spring 301 to improve energy storage efficiency, while preventing the leaf spring 301 from sliding and shifting, ensuring shock absorption stability.

[0046] like Figure 1 As shown, a guide assembly 202 is provided between the first connecting plate 1 and the second connecting plate 2. The guide assembly 202 is used to guide the relative sliding of the first connecting plate 1 and the second connecting plate 2. The guide assembly 202 constrains the relative sliding direction of the first and second connecting plates 2, preventing the support from undergoing horizontal torsion or overturning under complex vibrations, ensuring that the seismic force is transmitted along the design direction, and improving the overall structural reliability.
