Particularly in areas prone to natural disasters such as earthquakes, seismic isolation technology has become a crucial means of ensuring building safety. Spherical bearings, a key form of seismic isolation, are widely used in bridges, high-rise buildings, and other fields due to their unique structural and performance advantages.

[0031] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0032] The utility model provides a seismic isolation building support, including an upper support, a flat stainless steel plate, a flat wear-resistant plate, a spherical crown and a lower support assembly, the upper support is connected to the upper part of the bridge structure, and the lower support assembly is connected to the lower part of the bridge structure or the foundation part; the flat stainless steel plate is arranged on the upper support, the flat wear-resistant plate is arranged on the upper surface of the spherical crown, the flat stainless steel plate and the flat wear-resistant plate are fixedly connected or can be slidably connected along at least one preset direction; the curved surface of the spherical crown is slidably connected to the lower support assembly.

[0033] The combination of upper support, flat stainless steel plate, flat wear-resistant plate, spherical crown and lower support assembly has a simple overall structure and reasonable design compared to the traditional complex curved friction pair design, which reduces the difficulty of manufacturing and installation as well as the risk of failure caused by complex structure, and improves the stability, reliability and service life of the building support.

[0034] In addition, the flat stainless steel plate and the flat wear-resistant plate can be fixedly connected or slidably connected along at least one preset direction to meet the needs of different application scenarios and have a wide range of applications.

[0035] Furthermore, the flat wear-resistant plate is embedded in the upper surface of the spherical crown and protrudes from the spherical crown, thereby improving the connection stability between the flat wear-resistant plate and the spherical crown.

[0036] The surface area of ​​the flat stainless steel plate is greater than the surface area of ​​the flat wear-resistant plate, and is greater than the surface area of ​​the upper surface of the spherical crown.

[0037] As an optional implementation, the lower support assembly includes a curved wear-resistant plate, a seismic isolation ball seat, a rubber pressure plate and a lower support base. The lower support base is connected to the lower part or the foundation part of the bridge structure, and the lower support base is a groove-type seat. The curved wear-resistant plate, the seismic isolation ball seat and the rubber pressure plate are arranged in the lower support base from top to bottom. The curved surface of the curved wear-resistant plate is adapted to the spherical surface of the ball crown, and the two are slidingly connected.

[0038] Furthermore, the curved wear-resistant plate is embedded in the seismic isolation ball seat and protrudes from the seismic isolation ball seat.

[0039] Under external forces such as earthquakes, bridge structures experience a certain amount of displacement and rotation. This displacement and rotation is transmitted to the curved wear plate via the spherical cap. When subjected to force, the two slide relative to each other, dispersing the seismic energy through sliding friction and reducing the impact on the bridge structure. Furthermore, the rubber bearing plate provides elastic support, further absorbing and dispersing seismic energy. When subjected to force, the rubber bearing plate elastically deforms, converting seismic energy into elastic potential energy, reducing the vibration impact on the bridge structure. This achieves a vibration-damping and seismic-isolation effect on the bridge structure, effectively ensuring its safety and stability.

[0040] The corners of the upper support are provided with first connection holes for connecting with the upper part of the bridge structure.

[0041] A second connection hole is provided at the corner of the lower support base for connection to the lower part or foundation part of the bridge structure.

[0042] As an optional embodiment, a curved stainless steel plate is provided on the spherical surface of the spherical crown, and the curvature of the curved stainless steel plate, the curved wear-resistant plate and the upper surface of the seismic isolation ball seat is adapted to the curvature of the spherical surface of the spherical crown, and their central axes are collinearly arranged, and the surface area of ​​the curved stainless steel plate and the curved wear-resistant plate is smaller than the surface area of ​​the upper surface of the seismic isolation ball seat and the spherical surface of the spherical crown.

[0043] The function of the curved stainless steel plate is to reduce the sliding friction coefficient between it and the curved wear-resistant plate, which is beneficial to the dispersion and transmission of earthquake energy. It can also play a certain protective role on the spherical crown and reduce the wear of the spherical crown when it is subjected to force.

[0044] The surface area of ​​the curved stainless steel plate and the curved wear-resistant plate is smaller than the surface area of ​​the upper surface of the seismic isolation ball seat and the spherical surface of the ball crown. This is to ensure sufficient sliding area while reducing material usage.

[0045] As an optional implementation, when the flat stainless steel plate is fixedly connected to the flat wear-resistant plate, the outer edge of the lower surface of the upper support extends toward the lower support base to form a receiving groove, and is located on the outer side of the side plate of the lower support base, and there is partial overlap between the two.

[0046] This arrangement improves the connection stability and reliability between the spherical crown and the upper support.

[0047] As an optional embodiment, when the flat stainless steel plate and the flat wear-resistant plate can be slidably connected along the first horizontal direction, limiting protrusions are provided on opposite sides of the lower surface of the upper support, and the limiting protrusions are located on the outer side of the lower support base and extend parallel to the first horizontal direction.

[0048] The function of the limiting protrusion is to provide sliding guidance and limit the sliding range.

[0049] Since the bridge will deform under the influence of external environmental factors such as temperature changes, when the bridge deforms, the upper support moves accordingly, driving the flat stainless steel plate to slide in the first horizontal direction relative to the flat wear-resistant plate under the constraint of the limiting protrusion to cope with the deformation of the bridge.

[0050] It should be noted that the specific sliding structure between the flat stainless steel plate and the flat wear-resistant plate adopts existing technology, as long as the two can achieve sliding movement along the first horizontal direction within a preset safety range.

[0051] As an optional implementation, when the flat stainless steel plate and the flat wear-resistant plate are slidably connected along the first horizontal direction and the second horizontal direction, the upper support is a flat plate structure.

[0052] Furthermore, the first horizontal direction and the second horizontal direction are arranged vertically.

[0053] Since bridges will deform under the influence of external environmental factors such as temperature changes, when the bridge deforms, the upper support moves accordingly, driving the flat stainless steel plate to slide freely in two horizontal directions relative to the flat wear-resistant plate, allowing the bridge structure to move freely within a certain range to effectively cope with the deformation of the bridge.

[0054] It should be noted that the specific sliding structure between the flat stainless steel plate and the flat wear-resistant plate adopts existing technology, as long as the relative sliding movement between the two can be achieved along the first horizontal direction and the second horizontal direction within a preset safety range.

[0055] As an optional implementation, both the flat wear-resistant plate and the curved wear-resistant plate are made of polytetrafluoroethylene plates.

[0056] Furthermore, both the flat wear-resistant plate and the curved wear-resistant plate are made of polytetrafluoroethylene plates made of modified ultra-high molecular weight polyethylene, which has excellent self-lubricating properties and wear resistance, reduces the sliding friction coefficient between the flat wear-resistant plate and the flat stainless steel plate and between the curved wear-resistant plate and the curved stainless steel plate, and improves the shock absorption effect of the building support.

[0057] As an optional implementation, a first wing plate is provided on the upper support, and a second wing plate is provided on the lower support base, and is provided in a one-to-one correspondence with the first wing plate, and the two are connected by bolts.

[0058] Furthermore, the number of the first wing plates is four, and they are symmetrically arranged in pairs on both sides of the upper support. The second wing plates are arranged on the lower support base in a one-to-one correspondence with the first wing plates.

[0059] A first through hole is formed on the first wing plate, and a second through hole corresponding to the first through hole is formed on the second wing plate. Bolts pass through the first through hole and the second through hole in sequence to connect the upper support and the lower support base.

[0060] The first wing plate can also be provided with a connecting groove, which extends in a direction parallel to the side of the upper support. The second wing plate is provided with a second through hole corresponding to the arc segment of the connecting groove. The bolts pass through the connecting groove and the second through hole in sequence to connect the upper support and the lower support base.

[0061] During transportation, bolts passing through the first and second wing plates connect the upper support and lower base, providing protection and support. During assembly, this ensures proper alignment between the upper and lower bases, minimizing assembly deviations.

[0062] It should be noted that the first wing plate and the second wing plate are temporary auxiliary structures. After the assembly work between the upper support and the lower support base and the bridge is completed, the first wing plate and the second wing plate can be cut off to reduce the weight of the building support.

[0063] This utility model transmits force through the spherical surface of the spherical cap, avoiding force necking. The reaction force acting on the bridge structure is relatively uniform, ensuring flexible rotation of the building support. Furthermore, through the combined transmission of force through the spherical cap, curved wear-resistant plate, seismic isolation ball seat, and rubber pressure plate, the reaction force acting on the bridge structure is relatively uniform, achieving excellent force unloading. It is particularly suitable for wide and curved bridges, meeting the support requirements of bridges with large rotation angles.

[0064] Example 1:

[0065] like Figure 1-Figure 2 As shown, the utility model provides a seismic isolation building support, including an upper support 1, a flat stainless steel plate 2, a flat wear-resistant plate 3, a spherical crown 4 and a lower support assembly, the upper support 1 is connected to the upper part of the bridge structure, and the lower support assembly is connected to the lower part of the bridge structure or the foundation part; the flat stainless steel plate 2 is arranged on the upper support 1, the flat wear-resistant plate 3 is arranged on the upper surface of the spherical crown 4, the flat stainless steel plate 2 and the flat wear-resistant plate 3 are fixedly connected or can be slidably connected along at least one preset direction; the curved surface of the spherical crown 4 is slidably connected to the lower support assembly.

[0066] The combination of upper support 1, flat stainless steel plate 2, flat wear-resistant plate 3, spherical crown 4 and lower support assembly has a simple overall structure and reasonable design compared to the traditional complex curved surface friction pair design, which reduces the difficulty of manufacturing and installation and the risk of failure caused by complex structure, and improves the stability, reliability and service life of the building support.

[0067] In addition, the flat stainless steel plate 2 and the flat wear-resistant plate 3 can be fixedly connected or slidably connected along at least one preset direction to meet the needs of different application scenarios and have a wide range of applications.

[0068] Furthermore, the flat wear-resistant plate 3 is embedded on the upper surface of the spherical crown 4 and protrudes from the spherical crown 4 , thereby improving the connection stability between the flat wear-resistant plate 3 and the spherical crown 4 .

[0069] The surface area of ​​the flat stainless steel plate 2 is larger than the surface area of ​​the flat wear-resistant plate 3 .

[0070] As an optional embodiment, the lower support assembly includes a curved wear-resistant plate 6, a seismic isolation ball seat 7, a rubber pressure plate 8 and a lower support base 9. The lower support base 9 is connected to the lower part or the foundation part of the bridge structure, and the lower support base 9 is a groove-type seat. The curved wear-resistant plate 6, the seismic isolation ball seat 7 and the rubber pressure plate 8 are arranged in the lower support base 9 from top to bottom. The curved surface of the curved wear-resistant plate 6 is adapted to the spherical surface of the ball crown 4, and the two are slidingly connected.

[0071] Furthermore, the curved wear-resistant plate 6 is embedded in the seismic isolation ball seat 7 and protrudes from the seismic isolation ball seat 7 .

[0072] Under the action of external forces such as earthquakes, the bridge structure produces certain displacements and rotations. These displacements and rotations are transmitted to the curved wear-resistant plate 6 through the spherical cap 4. When subjected to force, the two slide relative to each other, dispersing the seismic energy through sliding friction, thereby reducing the impact on the bridge structure. In addition, the rubber pressure plate 8 provides elastic support to further absorb and disperse seismic energy. When subjected to force, the rubber pressure plate 8 undergoes elastic deformation, converting seismic energy into elastic potential energy, thereby reducing the vibration impact on the bridge structure. This achieves a shock-absorbing and seismic isolation effect on the bridge structure, effectively ensuring the safety and stability of the bridge structure.

[0073] First connection holes 14 are provided at the corners of the upper support 1 for connection with the upper part of the bridge structure.

[0074] Second connection holes 93 are provided at the corners of the lower support base 9 for connection to the lower part or foundation of the bridge structure.

[0075] As an optional embodiment, a curved stainless steel plate 5 is provided on the spherical surface of the spherical crown 4. The curvature of the curved stainless steel plate 5, the curved wear-resistant plate 6 and the upper surface of the seismic isolation ball seat 7 are adapted to the curvature of the spherical surface of the spherical crown 4, and their central axes are collinearly arranged. The surface area of ​​the curved stainless steel plate 5 and the curved wear-resistant plate 6 is smaller than the surface area of ​​the upper surface of the seismic isolation ball seat 7 and the spherical surface of the spherical crown 4.

[0076] The function of the curved stainless steel plate 5 is to reduce the sliding friction coefficient between it and the curved wear-resistant plate 6, which is beneficial to the dispersion and transmission of earthquake energy. It can also play a certain protective role on the spherical crown 4 and reduce the wear of the spherical crown 4 when subjected to force.

[0077] The surface areas of the curved stainless steel plate 5 and the curved wear-resistant plate 6 are smaller than the surface areas of the upper surface of the seismic isolation ball seat 7 and the spherical surface of the spherical crown 4. This arrangement is to ensure sufficient sliding area while reducing material usage.

[0078] As an optional implementation, when the flat stainless steel plate 2 is fixedly connected to the flat wear-resistant plate 3, the outer edge of the lower surface of the upper support 1 extends toward the lower support base 9 to form a receiving groove 11, and is located on the outside of the side plate 91 of the lower support base 9.

[0079] This arrangement improves the connection stability and reliability between the spherical cap 4 and the upper support 1 .

[0080] As an optional embodiment, the flat wear-resistant plate 3 and the curved wear-resistant plate 6 are both made of polytetrafluoroethylene plates.

[0081] Furthermore, the flat wear-resistant plate 3 and the curved wear-resistant plate 6 are both made of polytetrafluoroethylene plates made of modified ultra-high molecular weight polyethylene, which have excellent self-lubricating properties and wear resistance, reducing the sliding friction coefficient between the flat wear-resistant plate 3 and the flat stainless steel plate 2 and between the curved wear-resistant plate 6 and the curved stainless steel plate 5, thereby improving the shock absorption effect of the building support.

[0082] As an optional embodiment, a first wing plate 13 is provided on the upper support 1 , and a second wing plate 92 is provided on the lower support base 9 , and is provided in a one-to-one correspondence with the first wing plate 13 , and the two are connected by bolts 10 .

[0083] Furthermore, there are four first wing plates 13 symmetrically arranged in pairs on both sides of the upper support 1 . The second wing plates 92 are arranged on the lower support base 9 in a one-to-one correspondence with the first wing plates 13 .

[0084] A first through hole is defined on the first wing plate 13 , and a second through hole corresponding to the first through hole is defined on the second wing plate 92 . The bolt 10 passes through the first through hole and the second through hole in sequence to connect the upper support 1 and the lower support base 9 .

[0085] During transportation, the bolts 10 passing through the first wing plate 13 and the second wing plate 92 connect the upper support 1 and the lower support base 9, providing a certain degree of protection and support. Furthermore, during assembly, the upper support 1 and the lower support base 9 are correctly aligned, minimizing assembly deviations.

[0086] It should be noted that the first wing panel 13 and the second wing panel 92 serve as temporary auxiliary structures. After the assembly work between the upper support 1 and the lower support base 9 and the bridge is completed, the first wing panel 13 and the second wing panel 92 can be cut off to reduce the weight of the building support.

[0087] This utility model transmits force through the spherical surface of the spherical cap 4, avoiding force necking. The reaction force acting on the bridge structure is relatively uniform, ensuring flexible rotation of the building support. Furthermore, the spherical cap 4, curved wear-resistant plate 6, seismic isolation ball seat 7, and rubber pressure plate 8 jointly transmit force, making the reaction force acting on the bridge structure relatively uniform, achieving excellent force unloading. This is particularly suitable for wide and curved bridges, meeting the support requirements of bridges with large rotation angles.

[0088] Example 2:

[0089] The difference between Example 2 and Example 1 is that: Figure 3-Figure 4 As shown, the flat stainless steel plate 2 and the flat wear-resistant plate 3 can be slidably connected along the first horizontal direction, and limiting protrusions 12 are provided on the opposite sides of the lower surface of the upper support 1. The limiting protrusions 12 are located on the outer side of the side plate 91 of the lower support base 9 and extend parallel to the first horizontal direction.

[0090] Furthermore, the side plate 91 of the lower support base 9 partially overlaps with the limiting protrusion 12 .

[0091] The function of the limiting protrusion 12 is to provide a sliding guide and limit the sliding range.

[0092] Since the bridge will deform under the influence of external environmental factors such as temperature changes, when the bridge deforms, the upper support 1 moves accordingly, driving the flat stainless steel plate 2 to slide relative to the flat wear-resistant plate 3 in the first horizontal direction under the constraint of the limiting protrusion 12 to cope with the deformation of the bridge.

[0093] It should be noted that the specific sliding structure between the flat stainless steel plate 2 and the flat wear-resistant plate 3 adopts existing technology, as long as the two can achieve sliding movement along the first horizontal direction within a preset safety range.

[0094] As an optional embodiment, the first wing plate 13 can also be provided with a connecting groove 131, which extends in a side direction parallel to the upper support 1. The second wing plate 92 is provided with a second through hole corresponding to the arc segment of the connecting groove 131. The bolt 10 passes through the connecting groove 131 and the second through hole in sequence to connect the upper support 1 and the lower support base 9.

[0095] Example 3:

[0096] The difference between Example 3 and Example 1 is that: Figure 5-Figure 6 As shown, when the flat stainless steel plate 2 and the flat wear-resistant plate 3 are slidably connected along the first horizontal direction and the second horizontal direction, the upper support 1 is a flat plate structure.

[0097] Furthermore, the first horizontal direction and the second horizontal direction are arranged vertically.

[0098] Since the bridge will deform under the influence of external environmental factors such as temperature changes, when the bridge deforms, the upper support 1 moves accordingly, driving the flat stainless steel plate 2 to slide freely in two horizontal directions relative to the flat wear-resistant plate 3, so that the bridge structure can move freely within a certain range to effectively cope with the deformation of the bridge.

[0099] It should be noted that the specific sliding structure between the flat stainless steel plate 2 and the flat wear-resistant plate 3 adopts existing technology, as long as the relative sliding movement between the two can be achieved along the first horizontal direction and the second horizontal direction within a preset safety range.
