Description

Technical Field

[0001] This invention relates to the field of building structure technology, and in particular to a seismic isolation device. Background Technology

[0002] Seismic isolation technology for building structures is a new technology that emerged in the 1960s. For decades, scholars worldwide have conducted extensive and in-depth research on this technology. Traditional seismic resistance in building structures relies on damage to the structural components themselves, using inelastic deformation to dissipate seismic energy. Seismic isolation technology focuses on "isolation," employing specialized isolation elements and isolation layers to transform the structure's violent swaying under seismic loads into slow translational motion. The entire superstructure remains essentially in an elastic state, effectively preventing the transmission of seismic waves to the upper structure, reducing the seismic response of the superstructure, and significantly improving the building's seismic reliability and safety.

[0003] When an earthquake occurs, the ground soil becomes loose, and cracks appear in some areas, causing land subsidence in certain locations. As the land subsides, the seismic isolation devices supporting the building also become tilted. At this time, the support of the seismic isolation devices for the building will be greatly reduced, which can easily lead to accidents such as building collapse due to insufficient support. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a seismic isolation device that solves the technical problem of insufficient support for buildings caused by partial ground subsidence.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the main technical solutions adopted by the present invention include:

[0008] This invention provides a seismic isolation device, including a main support seismic isolation assembly and an auxiliary support seismic isolation assembly. The main support seismic isolation assembly and the auxiliary support seismic isolation assembly are arranged at intervals on the lower side of a building to support the building. The main support seismic isolation assembly includes a vertically arranged metal support sleeve and a rubber buffer column coaxially arranged inside the metal support sleeve. The rubber buffer column supports the lower part of the building. The auxiliary support seismic isolation assembly includes a vertically arranged metal support platform and a support column vertically arranged at the upper end of the metal support platform. The top of the support column is fixed to the lower part of the building. A ring of support insertion holes is vertically opened on the upper surface of the metal support platform. The lower ends of the support insertion holes on the same metal support platform are connected. The metal support platform is filled with a non-Newtonian fluid in the support insertion holes. The support column is vertically slidably and sealed into the support insertion holes and contacts the non-Newtonian fluid.

[0009] This invention discloses a seismic isolation device. When used, a main support seismic isolation assembly and an auxiliary support seismic isolation assembly are arranged in a uniformly spaced array and supported on the lower part of a building. The rubber buffer columns of the main support seismic isolation assembly are vertically supported on the lower part of the building under the constraint of metal support sleeves. In the event of a natural disaster such as an earthquake, the buffer rubber columns can deform to reduce the vibration transmitted to the building. The auxiliary support seismic isolation assembly is supported on the lower part of the building by its top support columns. When vibration occurs, causing the metal support platform to tilt or vibrate, the building's force on the support columns... The force will change. At the instant the force changes, the support column, supported by the non-Newtonian fluid, will provide sufficient support to the building. Subsequently, the support column under greater force will retract into the support socket, thereby squeezing the non-Newtonian fluid in the support socket. The non-Newtonian fluid in the support socket will then squeeze the remaining support columns to move upward along the support socket, thus continuing to provide support. Even if the bottom of the building tilts, this auxiliary support isolation component can still provide good support for the building, so that this isolation device can provide better support while isolating the seismic waves.

[0010] Optionally, a connecting rod is horizontally arranged between adjacent metal support sleeves and metal support platforms.

[0011] By installing connecting rods between adjacent metal support sleeves and metal support platforms, all main support isolation components and auxiliary support isolation components are connected into a whole through the connecting rods, thereby improving the overall integrity of the entire isolation device, and thus improving the stability of the isolation component and its support for the building during an earthquake.

[0012] Optionally, a severing column is vertically arranged between adjacent metal support sleeves and metal support platforms, with the lower end of the severing column fixed to the ground and the upper end of the severing column fixed to the middle of the lower end of the connecting rod.

[0013] By connecting rods, all main and auxiliary seismic isolation components are horizontally integrated. However, when an earthquake causes horizontal ground tearing, if one component is subjected to horizontal ground movement, the connecting rods may cause other components to move, affecting the support. In this solution, a vertically truncated support column is installed in the middle of the support rod. This column provides vertical support to the connecting rod. When the connecting rod is subjected to horizontal tension, the truncated support column can disperse the tension, reducing the impact on other components. Furthermore, when the tension is too large, the connection point between the connecting rod and the truncated support column will deform. In this case, the truncated support column can directly cut off the middle of the connecting rod, thus disconnecting the two sets of components, making it safer and improving the support of the seismic isolation device for the building at the epicenter.

[0014] Optionally, a secondary support seismic isolation component is provided at the center of the area enclosed by the adjacent main support seismic isolation component and the auxiliary support seismic isolation component. The secondary support seismic isolation component includes a base plate horizontally abutting the ground, a top plate horizontally abutting the lower part of the building, a top column vertically connected between the base plate and the top plate, and a rubber buffer ring coaxially sleeved around the top column and abutting against the base plate and the top plate at one end close to each other.

[0015] By setting secondary support isolation components at the center of each pair of adjacent main support isolation components and auxiliary support isolation components, the secondary support isolation components can work together with the main support isolation components and auxiliary support isolation components to support the building, thereby improving the support effect.

[0016] Optionally, the rubber buffer ring includes rubber rings and metal rings stacked coaxially from bottom to top, and a buffer cavity is formed between the rubber buffer ring and the top column, and the buffer cavity is filled with concrete.

[0017] By setting the rubber buffer ring to be formed by alternating stacking of rubber rings and metal rings, the rubber buffer ring has sufficient support while also having certain deformation buffering characteristics. At the same time, concrete is poured into the buffer cavity between the rubber buffer ring and the top column, which makes the overall support of the seismic isolation device better.

[0018] Optionally, a steel mesh is laid under the base plate, the metal support sleeve, and the metal support platform. The base plate, the metal support sleeve, and the metal support platform are all welded and fixed to the steel mesh, and concrete is poured inside the steel mesh.

[0019] By laying steel mesh at the bottom of the base plate, metal support sleeve, and metal support platform, and welding the steel mesh to the bottom of the base plate, metal support sleeve, and metal support platform, and then pouring concrete into the steel mesh, the main support isolation component, auxiliary support isolation component, and secondary support isolation component are integrated into a whole, thereby improving the overall integrity of the entire isolation device.

[0020] Optionally, a support plate is ball-jointed at the top of the support column, and a cushioning rubber sheet is adhered to the upper surface of the support plate.

[0021] By ball-jointing a support plate at the top of the support column and bonding a buffer rubber sheet to the top of the support plate, the buffering effect between the support column and the building can be increased through the buffer rubber sheet. At the same time, when the bottom auxiliary support seismic isolation component tilts due to an earthquake, the support plate at the top of the support column can still abut against the lower part of the building, thus providing relatively good support.

[0022] Optionally, the support column is provided with a vertical circumferential reinforcing rib at the middle peripheral end.

[0023] When the auxiliary support and seismic isolation components tilt, the support column will also tilt to support the building. At this time, part of the pressure from the building will still be applied vertically to the support column, causing the support column to bear the vertical gravity in an inclined posture. The middle part of the support column exposed at the support insertion hole is prone to bending. In this solution, reinforcing ribs are set on the peripheral end of the middle part of the support column to improve the bending resistance of the support column, thereby improving the support effect.

[0024] Optionally, the rubber buffer column has multiple metal rods integrally embedded along its length, and the multiple metal rods are arranged at uniform intervals.

[0025] The support strength of the rubber buffer column is improved by embedding metal rods inside it.

[0026] Optionally, the top of the rubber buffer column is provided with a fixing member that supports the lower part of the building. The fixing member has multiple fasteners that rotate and abut against and insert into the side end of the rubber buffer column at even intervals around its periphery. The fasteners are fixed to the side end of the rubber buffer column by bolts, and the top of the fixing member is fixed to the lower part of the building.

[0027] By installing fasteners at the top of the rubber buffer column, the rubber buffer column can be directly fixed to the bottom of the building, thereby fixing the entire seismic isolation device to the building.

[0028] (III) Beneficial Effects

[0029] The beneficial effects of this invention are as follows: When the seismic isolation device of this invention is used, the main support seismic isolation assembly and the auxiliary support seismic isolation assembly are arranged in a uniformly spaced array and supported on the lower part of the building. The rubber buffer columns of the main support seismic isolation assembly are vertically supported on the lower part of the building under the constraint of the metal support sleeve. When a natural disaster such as an earthquake occurs, the buffer rubber columns can deform to reduce the vibration transmitted to the building. The auxiliary support seismic isolation assembly is supported on the lower part of the building by the support columns at the top. When vibration occurs and causes the metal support platform to tilt or vibrate, the building acts on the support columns. The force will change. At the instant the force changes, the support column, supported by the non-Newtonian fluid, will provide sufficient support to the building. Subsequently, the support column under greater force will retract into the support hole, thereby squeezing the non-Newtonian fluid in the support hole. The non-Newtonian fluid in the support hole will then squeeze the remaining support columns to move upward along the support hole, thus continuing to provide support. Even if the bottom of the building tilts, this auxiliary support isolation component can still provide good support for the building, so that this isolation device can play a better supporting role while isolating the seismic waves.

[0036] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] The seismic isolation device proposed in this invention, when used, has a main support seismic isolation assembly and an auxiliary support seismic isolation assembly arranged in a uniformly spaced array to support the lower part of the building. The rubber buffer columns of the main support seismic isolation assembly are vertically supported at the lower part of the building under the constraint of metal support sleeves. In the event of a natural disaster such as an earthquake, the buffer rubber columns can deform to reduce the vibration transmitted to the building. The auxiliary support seismic isolation assembly is supported at the lower part of the building by its top support columns. When vibration occurs causing the metal support platform to tilt or vibrate, the force exerted by the building on the support columns... The situation will change. At the moment the force changes, the support column, supported by the non-Newtonian fluid, will provide sufficient support to the building. Subsequently, the support column under greater force will retract into the support socket, thereby squeezing the non-Newtonian fluid in the support socket. The non-Newtonian fluid in the support socket will then squeeze the remaining support columns to move upward along the support socket, thus continuing to provide support. Even if the bottom of the building tilts, this auxiliary support isolation component can still provide good support for the building, allowing this isolation device to provide better support while isolating the seismic waves.

[0038] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0039] Reference Figure 1 and Figure 2 A seismic isolation device includes a main support seismic isolation component 1, a secondary support seismic isolation component 3, and an auxiliary support seismic isolation component 2.

[0040] The main support isolation component 1 and the auxiliary support isolation component 2 are arranged in a spaced array on the lower side of the building. The secondary support isolation component 3 is located at the center of each of the two adjacent sets of main support isolation components 1 and auxiliary support isolation components 2. The main support isolation component 1, the secondary support isolation component 3 and the auxiliary support isolation are used to support the building.

[0041] See Figure 1 and Figure 2 The main support isolation component 1 includes a vertically arranged metal support sleeve 11 and a rubber buffer column 12 coaxially inserted inside the metal support sleeve 11. The rubber buffer column 12 is supported at the lower part of the building. Multiple metal rods 121 are integrally formed inside the rubber buffer column 12 along its own length direction. The multiple metal rods 121 are arranged at uniform intervals. A fixing member 122 supporting the lower part of the building is provided at the top of the rubber buffer column 12. Multiple fasteners 1221 are evenly spaced around the periphery of the fixing member 122, which rotate and abut against and insert into the side end of the rubber buffer column 12. The fasteners 1221 are fixed to the side end of the rubber buffer column 12 by bolts. The top of the fixing member 122 is fixed to the lower part of the building.

[0042] See Figure 1 and Figure 3The auxiliary support and vibration isolation assembly 2 includes a vertically arranged metal support platform 21 and a support column 22 vertically arranged on the upper end of the metal support platform 21. The top of the support column 22 is fixed to the lower part of the building. A ring of support holes 211 is vertically opened on the upper surface of the metal support platform 21. The lower ends of the support holes 211 on the same metal support platform 21 are connected. The metal support platform 21 is filled with a non-Newtonian fluid in the support holes 211. The support column 22 is vertically slidably and sealed into the support holes 211 and contacts the non-Newtonian fluid. When vibration occurs and causes the metal support platform 21 to tilt or vibrate, the force exerted by the building on the support column 22 will change. At the moment of force change, the support column 22, supported by the non-Newtonian fluid, will provide sufficient support for the building. Subsequently, the support column 22, which is subjected to a larger force, will retract into the support socket 211, thereby squeezing the non-Newtonian fluid in the support socket 211. The non-Newtonian fluid in the support socket 211 will then squeeze the remaining support columns 22 to move upward along the support socket 211, thereby continuing to provide support. Even if the bottom of the building tilts, the auxiliary support and vibration isolation component 2 can still provide good support for the building.

[0043] Multiple reinforcing ribs 221 are vertically welded to the circumferential end of the middle section of the support column 22. By providing reinforcing ribs 221 at the circumferential end of the middle section of the support column 22, the bending resistance of the support column 22 is improved.

[0044] The top of the support column 22 is ball-jointed with a support plate 222, and a buffer rubber sheet 223 is bonded to the upper surface of the support plate 222. This allows the buffer rubber sheet to increase the buffering effect between the support column 22 and the building. At the same time, when the bottom auxiliary support seismic isolation component 2 tilts due to an earthquake, the support plate 222 at the top of the support column 22 can still abut against the lower part of the building, thus providing relatively good support.

[0045] See Figure 1 and Figure 3 The secondary support seismic isolation component 3 includes a base plate 31 horizontally abutting the ground, a top plate 32 horizontally abutting the lower part of the building, a top column 33 vertically welded between the base plate 31 and the top plate 32, and a rubber buffer ring 34 coaxially sleeved around the top column 33 and abutting against the base plate 31 and the top plate 32 at one end close to each other. The rubber buffer ring 34 includes rubber rings 341 and metal rings 342 stacked coaxially from bottom to top. A buffer cavity 343 is formed between the rubber buffer ring 34 and the top column 33, and concrete is poured into the buffer cavity 343.

[0046] See Figures 1 to 4A steel mesh 4 is laid under the base plate 31, the metal support sleeve 11, and the metal support platform 21. The base plate 31, the metal support sleeve 11, and the metal support platform 21 are all welded and fixed to the steel mesh 4, and concrete is poured inside the steel mesh 4. The main support isolation component 1, the auxiliary support isolation component 2, and the secondary support isolation component 3 are integrated into a whole, thereby improving the overall integrity of the entire isolation device.

[0047] A connecting rod 5 is horizontally welded between adjacent metal support sleeves 11 and metal support platforms 21. A vertically installed severing column 6 is installed between adjacent metal support sleeves 11 and metal support platforms 21. The lower end of the severing column 6 is welded to the reinforcing mesh 4 and cast together, and the upper end of the severing column 6 is welded to the middle of the lower end of the connecting rod 5. The connecting rod 5 forms a whole in the horizontal direction with all the main support isolation components 1 and auxiliary support isolation components 2. The severing column 6 provides vertical support for the connecting rod 5. When the connecting rod 5 is subjected to horizontal tension, the severing column 6 can disperse the tension and reduce the impact on other components. On the other hand, when the tension is too large, the connection point between the middle of the connecting rod 5 and the severing column 6 will deform. At this time, the severing column 6 can directly cut off the middle of the connecting rod 5, thereby disconnecting the two sets of components, which is safer.
