Description

Technical Field

[0001] The present invention relates to the technical field of seismic isolation / vibration isolation bearings, and particularly relates to a three-dimensional seismic isolation / vibration isolation bearing combining a high-damping alloy vibration reduction transverse groove spring and a lead core. Background Art

[0002] The lessons of earthquake disasters are quite heavy, and an earthquake is a complex three-dimensional spatial motion, including horizontal (X, Y directions) and vertical directions of motion. Therefore, in the exploration of solutions to earthquake disasters, the seismic isolation technology has developed rapidly, and a relatively perfect system has been formed in terms of standards, regulations, policies and technical measures. Traditional seismic isolation bearings can only achieve seismic isolation in the horizontal direction. For example: laminated rubber seismic isolation bearings, lead core rubber seismic isolation bearings, friction pendulum seismic isolation bearings, etc. However, in recent years, due to the seismic motion in the horizontal direction, the number of damaged buildings has gradually increased. Therefore, a vertical seismic isolation system needs to be added, and three-dimensional seismic isolation bearings have gradually developed. Most traditional seismic isolation bearings can only achieve seismic isolation in the horizontal direction and cannot perform vertical seismic isolation, and they have high manufacturing costs and complex processes. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this purpose, the present invention provides a three-dimensional seismic isolation / vibration isolation bearing combining a high-damping alloy vibration reduction transverse groove spring and a lead core, which has excellent earthquake energy absorption ability; high energy dissipation efficiency; sufficient stiffness; excellent durability and long service life; simple structure and convenient construction; and the lead core can be replaced. This seismic isolation bearing can achieve three-dimensional seismic isolation through high-performance damping alloys and innovative combined structures, effectively consume the energy input into the structure by earthquakes, and enable the structure to meet the requirements of national seismic codes.

[0004] The three-dimensional seismic isolation / vibration isolation bearing combining a high-damping alloy vibration reduction transverse groove spring and a lead core according to an embodiment of the present invention includes:

[0005] A lower connecting plate;

[0006] A transverse groove spring installed on the lower connecting plate, the transverse groove spring having a central hole, the transverse groove spring including a plurality of coils and a plurality of support blocks, the plurality of coils being uniformly spaced along the axial direction of the transverse groove spring, two of the support blocks being connected between adjacent two of the coils, the central connection line of the two support blocks between adjacent two of the coils being line a, line a intersecting the axis of the transverse groove spring, and adjacent two lines a along the axial direction of the transverse groove spring being perpendicular to each other;

[0007] A lead core installed in the central hole of the transverse groove spring;

[0008] An upper connecting plate installed at an end of the transverse groove spring away from the lower connecting plate.

[0009] The high damping alloy vibration-damping transverse groove spring and lead core combined three-dimensional seismic isolation / vibration support according to the embodiment of the present invention has at least the following beneficial effects: when the upper connecting plate and the lower connecting plate are shear-deformed, the upper connecting plate and the lower connecting plate drive the lead core to realize shear deformation energy consumption, and when the upper connecting plate and the lower connecting plate drive the transverse groove spring to shear deformation, the transverse groove spring drives the entire lead core to realize shear energy consumption, and the transverse groove spring makes the shear deformation of the lead core more uniform, more lead core enters the elastic-plastic state to consume energy, increases the deformation capacity of the lead core, improves the stability of the seismic isolation support, and makes the deformation mode of the lead core more uniform. During axial deformation, the transverse groove spring is used to realize tensile and compressive energy consumption; during shear deformation, the transverse groove spring and the lead core are used to realize shear energy consumption, and the energy consumption efficiency is higher. Since the device adopts the transverse groove spring, it has the ability of self-resetting in the vertical direction, and at the same time, the axial compressive bearing capacity and energy consumption capacity of the device are much greater than the axial tensile bearing capacity and energy consumption capacity. The device has self-recovery ability under vertical compression and has three-dimensional deformation and energy consumption capacity.

[0010] The seismic isolation bearing of the embodiment of the present invention has excellent ability to absorb earthquake energy; high energy consumption efficiency; sufficiently large rigidity; excellent durability and long service life; simple structure and easy construction; and replaceable lead core. This seismic isolation bearing can achieve three-dimensional seismic isolation through high-performance damping alloy and innovative combination structure, which will effectively consume the energy input into the structure by the earthquake, so that the structure meets the requirements of national seismic code.

[0011] According to some embodiments of the present invention, the upper connecting plate and the lower connecting plate are made of metal, which can be a stainless steel plate, a common carbon steel plate or a copper plate. The upper connecting plate and the lower connecting plate are metal plates with high strength and excellent durability. This enables the metal connecting plates to withstand large loads, including the huge impact force caused by natural disasters such as earthquakes. At the same time, the metal material has strong corrosion resistance, which can meet the needs of long-term use of buildings and reduce safety hazards caused by material aging.

[0012] According to some embodiments of the present invention, the cross-sections of the upper connecting plate and the lower connecting plate are square, rectangular or polygonal. The cross-sections of the upper connecting plate and the lower connecting plate are regular patterns, which are convenient for processing and manufacturing, and convenient for alignment and fixing with the basic structure, and can improve installation efficiency. When subjected to force, the load can be evenly distributed, stress concentration can be reduced, and deformation resistance is better, which helps to enhance the structural stability of the entire seismic isolation support.

[0013] According to some embodiments of the present invention, upper connection holes are provided at the corners of the upper connection plate, and lower connection holes are provided at the corners of the lower connection plate. The upper connection holes and the lower connection holes are for metal to pass through. For component installation, two groove supports are pre-set at intervals up and down in a building. The upper connection plate and the lower connection plate are respectively installed in the upper and lower groove supports, and then bolts are used to pass through the upper connection holes and the lower connection holes to install the upper connection plate and the lower connection plate into the upper and lower groove seats.

[0014] According to some embodiments of the present invention, a plurality of transverse grooves communicating with the central hole are provided on the transverse groove spring. The surrounding spaces formed by two adjacent ring bodies and the support blocks between the two ring bodies form the two transverse grooves. The two ends of the support block along the axial direction of the transverse groove spring respectively correspond to the middle parts of the two transverse grooves. When the transverse groove spring is subjected to an axial pressure, the support block axially squeezes the ring bodies at both ends along the axial direction of the transverse groove spring, and the width of the middle part corresponding to the transverse groove decreases, facilitating the axial elastic deformation of the transverse groove spring.

[0015] According to some embodiments of the present invention, a relief hole is provided on the upper connection plate. The relief hole communicates with the central hole, and the aperture of the relief hole is larger than the outer diameter of the lead core. When the seismic isolation bearing deforms axially and the upper connection plate and the lower connection plate approach each other axially, the upper connection plate and the lower connection plate squeeze the transverse groove spring, and the lead core located in the transverse groove spring can pass through the relief hole, which can prevent the lead core from abutting against the upper connection plate and the lower connection plate and thus affecting the axial deformation amount of the transverse groove spring.

[0016] According to some embodiments of the present invention, the lead core is cylindrical, and the surface of the lead core abuts against the inner wall of the central hole. The outer surface of the lead core abutting against the inner wall of the central hole can ensure the stability of the lead core in the seismic isolation bearing. Under the action of an earthquake or external load, the lead core may be subjected to various forces, and this design can effectively prevent the lead core from shifting or shaking, thus ensuring the stability and reliability of the bearing. As a high-damping material, the lead core can effectively absorb and dissipate seismic energy through plastic deformation during an earthquake. The wrapping of the transverse groove spring not only provides a stable support environment for the lead core but also helps the lead core better play its energy-dissipating role. The elastic deformation of the transverse groove spring can also absorb energy to a certain extent, complementing the energy-dissipating role of the lead core and jointly improving the seismic performance of the bearing.

[0017] According to some embodiments of the present invention, the lead core abuts against the lower connection plate, and the upper connection plate is spaced apart from the lead core. The upper connection plate does not directly contact the lead core under the design load and leaves a certain gap, enabling the transverse groove spring to achieve axial energy dissipation and axial seismic isolation capabilities.

[0018] According to some embodiments of the present invention, a protective layer is provided on the surface of the lead core. The outer surface of the protective layer abuts against the inner wall of the central hole, and the protective layer is made of rubber material. However, an outer rubber protective layer can also be used, or a lead core rubber bearing. The shear steel plate in the lead core rubber bearing makes its shear deformation more uniform. The rubber isolation bearing utilizes the elastic characteristics of the rubber material and can absorb a large amount of seismic energy through the shear deformation of the bearing during an earthquake. This ability effectively reduces the seismic force transmitted to the superstructure, thereby protecting the structural integrity of the building. By embedding a lead core in the rubber bearing, the bearing capacity of the bearing is improved, and the damping effect is increased. The plastic deformation of the lead core can further consume seismic energy, enabling more effective consumption of seismic energy inside the bearing.

[0019] According to some embodiments of the present invention, the material of the transverse groove spring is MnCu alloy. It has characteristics such as high strength, high damping, processability, wide temperature range, radiation resistance, and long service life. The lead core has stable performance, good shear performance, and is easy to obtain and manufacture. The high-damping alloy vibration-damping transverse groove spring and the lead core work together to consume energy, achieving three-dimensional seismic isolation.

[0020] According to some embodiments of the present invention, the centers of the lower connecting plate, the transverse groove spring, the lead core, and the upper connecting plate are located on the same vertical line. When the centers of the upper connecting plate, the lower connecting plate, the lead core, and the transverse groove spring are on the same vertical line, it can ensure that the lead core can undergo uniform and effective shear deformation when subjected to external forces, thereby fully exerting its shock-absorbing and energy-consuming effects. It can ensure that when subjected to external forces, the mechanical transmission path of the entire seismic isolation system is clearer and more stable. This helps to reduce structural damage caused by unclear or unstable mechanical transmission paths. The lead core has good plastic deformation ability and energy absorption ability and is an ideal elastoplastic body.

[0021] According to some embodiments of the present invention, a spring protective layer is wrapped and connected to the surface of the transverse groove spring. Positioning protrusions are provided on the inner wall of the spring protective layer. The positioning protrusions extend into the transverse grooves, and notch grooves are provided on the positioning protrusions. The spring protective layer is wrapped and connected to the outside of the transverse groove spring, which can protect the transverse groove spring, prevent pollutants from adhering to the transverse groove spring, and improve the service life of the transverse groove spring. The positioning protrusions are snapped into the transverse grooves, which can improve the connection stability between the spring protective layer and the transverse groove spring. Notch grooves are provided on the positioning protrusions, and the positioning protrusions are annularly arranged, enabling the transverse groove spring to deform normally when subjected to axial pressure.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] Please refer to Figure 1 、 Figure 2 and Figure 3 According to an embodiment of the present invention, a three-dimensional isolation / vibration isolation support combining a high-damping alloy vibration-damping transverse groove spring and a lead core includes a lower connecting plate 100, a transverse groove spring 200, a lead core 300, and an upper connecting plate 400. The transverse groove spring 200 is mounted on the lower connecting plate 100. The transverse groove spring 200 has a central hole 210. The transverse groove spring 200 includes a plurality of coils 220 and a plurality of support blocks 230. The plurality of coils 220 are uniformly spaced along the axial direction of the transverse groove spring 200. Two support blocks 230 are connected between adjacent two coils 220. The central connection line of the two support blocks 230 between adjacent two coils 220 is line a. Line a intersects the axis of the transverse groove spring 200. Adjacent two lines a along the axial direction of the transverse groove spring 200 are perpendicular to each other. The lead core 300 is mounted in the central hole 210 of the transverse groove spring 200. The upper connecting plate 400 is mounted at one end of the transverse groove spring 200 away from the lower connecting plate 100.

[0040] When the upper connecting plate 400 and the lower connecting plate 100 undergo shear deformation, the upper connecting plate 400 and the lower connecting plate 100 drive the lead core 300 to achieve shear deformation energy dissipation. Moreover, when the upper connecting plate 400 and the lower connecting plate 100 drive the transverse groove spring 200 to undergo shear deformation, the transverse groove spring 200 drives the entire lead core 300 to achieve shear energy dissipation. The transverse groove spring 200 makes the shear deformation of the lead core 300 more uniform, more lead cores 300 enter the elastoplastic state for energy dissipation, increases the deformation ability of the lead core 300, improves the stability of the isolation bearing, and makes the deformation mode of the lead core 300 more uniform. During axial deformation, the transverse groove spring 200 is used to achieve tension and compression energy dissipation; during shear deformation, the transverse groove spring 200 and the lead core 300 are used to achieve shear energy dissipation, and the energy dissipation efficiency is higher. Since the transverse groove spring 200 is adopted in this device, it has self-resetting ability in the vertical direction. At the same time, the axial compression bearing capacity and energy dissipation capacity of this device are much greater than the axial tension bearing capacity and energy dissipation capacity. This device has self-recovery ability under vertical compression and has three-dimensional deformation and energy dissipation capabilities.

[0041] The isolation bearing of the embodiment of the present invention has excellent ability to absorb seismic energy; high energy dissipation efficiency; sufficient stiffness; excellent durability and long service life; simple structure and convenient construction; the lead core 300 can be replaced. This isolation bearing can achieve three-dimensional isolation through high-performance damping alloys and innovative combined structures, can effectively consume the energy input into the structure by the earthquake, and enable the structure to meet the requirements of the national seismic code.

[0042] In some embodiments, referring to Figure 1 、 Figure 2 and Figure 3 ,the materials of the upper connecting plate 400 and the lower connecting plate 100 are metals, which can be stainless steel plates, ordinary carbon steel plates or copper plates. The upper connecting plate 400 and the lower connecting plate 100 are metal plates, having high strength and excellent durability. This enables the metal connecting plates to bear large loads, including the huge impact forces brought by natural disasters such as earthquakes. At the same time, the metal material has strong corrosion resistance, can meet the long-term use needs of buildings, and reduces potential safety hazards caused by material aging.

[0043] In some embodiments, referring to Figure 1 、 Figure 2 and Figure 3 ,the cross-sections of the upper connecting plate 400 and the lower connecting plate 100 are square, rectangular or polygonal. The cross-sections of the upper connecting plate 400 and the lower connecting plate 100 are regular figures, which are convenient for processing and manufacturing, convenient for aligning and fixing with the foundation structure, and can improve the installation efficiency. When stressed, the load can be evenly distributed, the stress concentration phenomenon can be reduced, it has better anti-deformation ability, and helps to enhance the structural stability of the entire isolation bearing.

[0044] In some embodiments, referring to Figure 1 、Figure 2 and Figure 3 , upper connection holes 420 are provided at the corners of the upper connection plate 400, and lower connection holes 110 are provided at the corners of the lower connection plate 100. The upper connection holes 420 and the lower connection holes 110 are for metal to pass through. For component installation, two groove supports are provided at intervals above and below in a building in advance. The upper connection plate 400 and the lower connection plate 100 are respectively installed in the upper and lower groove supports, and then bolts are used to pass through the upper connection holes 420 and the lower connection holes 110 to install the upper connection plate 400 and the lower connection plate 100 into the upper and lower groove seats.

[0045] In some embodiments, referring to Figure 1 、 Figure 2 and Figure 3 , a plurality of transverse grooves 240 communicating with the central hole 210 are provided on the transverse groove spring 200. The enclosed spaces between adjacent two coil bodies 220 and the support blocks 230 between the two coil bodies 220 form two transverse grooves 240. The two ends of the support block 230 along the axial direction of the transverse groove spring 200 respectively correspond to the middle parts of the two transverse grooves 240. When the transverse groove spring 200 is subjected to an axial pressure, the support block 230 squeezes the coil bodies 220 at both ends along the axial direction of the transverse groove spring 200, and the width of the middle part of the corresponding transverse groove 240 decreases, facilitating the axial elastic deformation of the transverse groove spring 200.

[0046] In some embodiments, referring to Figure 1 、 Figure 2 and Figure 3 , an avoidance hole 410 is provided on the upper connection plate 400. The avoidance hole 410 communicates with the central hole 210, and the aperture of the avoidance hole 410 is larger than the outer diameter of the lead core 300. When the isolation bearing deforms axially and the upper connection plate 400 and the lower connection plate 100 approach each other axially, the upper connection plate 400 and the lower connection plate 100 squeeze the transverse groove spring 200, and the lead core 300 located in the transverse groove spring 200 can pass through the avoidance hole 410, which can prevent the lead core 300 from abutting against the upper connection plate 400 and the lower connection plate 100 and thus affecting the axial deformation amount of the transverse groove spring 200.

[0047] In some embodiments, referring to Figure 1 、 Figure 2 and Figure 4, the lead core 300 is cylindrical, and the surface of the lead core 300 abuts against the inner wall of the central hole 210. The abutment of the outer surface of the lead core 300 against the inner wall of the central hole 210 can ensure the stability of the lead core 300 in the seismic isolation bearing. Under the action of an earthquake or external load, the lead core 300 may be subjected to various forces, and this design can effectively prevent the lead core 300 from shifting or swaying, thus ensuring the stability and reliability of the bearing. As a high-damping material, the lead core 300 can effectively absorb and dissipate seismic energy through plastic deformation during an earthquake. The wrapping of the cross-grooved spring 200 not only provides a stable supporting environment for the lead core 300, but also helps the lead core 300 to better play its energy-dissipating role. The elastic deformation of the cross-grooved spring 200 can also absorb energy to a certain extent, complementing the energy-dissipating effect of the lead core 300 and jointly improving the seismic performance of the bearing.

[0048] In some embodiments, referring to Figure 1 , Figure 2 and Figure 3 , the lead core 300 abuts against the lower connecting plate 100, and the upper connecting plate 400 is arranged at an interval from the lead core 300. The upper connecting plate 400 does not directly contact the lead core 300 under the design load and leaves a certain gap, enabling the cross-grooved spring 200 to achieve axial energy dissipation and axial seismic isolation capabilities.

[0049] In some embodiments, referring to Figure 1 , Figure 2 and Figure 3 , a protective layer is provided on the surface of the lead core 300, and the outer surface of the protective layer abuts against the inner wall of the central hole 210. The protective layer is made of rubber material. Wrapping the rubber protective layer can also form a lead rubber bearing. The shear steel plate in the lead rubber bearing makes its shear deformation more uniform. The rubber seismic isolation bearing utilizes the elastic characteristics of the rubber material and can absorb a large amount of seismic energy through the shear deformation of the bearing during an earthquake. This ability effectively reduces the seismic force transmitted to the superstructure, thus protecting the structural integrity of the building. By embedding the lead core 300 in the rubber bearing, the bearing capacity of the bearing is improved and the damping effect is increased. The plastic deformation of the lead core 300 can further consume seismic energy, enabling the seismic energy to be more effectively consumed inside the bearing.

[0050] In some embodiments, referring to Figure 1 , Figure 2 and Figure 3 , the material of the cross-grooved spring 200 is MnCu alloy. It has characteristics such as high strength, high damping, processability, wide temperature range, radiation resistance, and long service life. The lead core 300 has stable performance, good shear performance, and is easy to obtain and manufacture. The high-damping alloy vibration-damping cross-grooved spring 200 and the lead core 300 work together to dissipate energy and achieve three-dimensional seismic isolation.

[0051] In some embodiments, referring toFigure 1 , Figure 2 and Figure 3 , the centers of the lower connecting plate 100, the transverse groove spring 200, the lead core 300, and the upper connecting plate 400 are located on the same vertical line. When the centers of the upper connecting plate 400, the lower connecting plate 100, the lead core 300, and the transverse groove spring 200 are on the same vertical line, it can ensure that the lead core 300 can undergo uniform and effective shear deformation when subjected to an external force, thereby fully exerting its shock absorption and energy dissipation function. It can ensure that when subjected to an external force, the mechanical transmission path of the entire isolation system is clearer and more stable. It helps to reduce structural damage caused by unclear or unstable mechanical transmission paths. The lead core 300 has good plastic deformation ability and energy absorption ability, and is an ideal elastoplastic body.

[0052] In some embodiments, referring to Figure 1 , Figure 2 and Figure 5 , a spring protective layer 500 is wrapped and connected to the surface of the transverse groove spring 200.

The spring protective layer 500 has an inner hole 510, and the transverse groove spring 200 is arranged in the inner hole 510. The spring protective layer 500 is wrapped and connected to the outside of the transverse groove spring 200, which can protect the transverse groove spring 200, prevent contaminants from adhering to the transverse groove spring 200, and improve the service life of the transverse groove spring 200.
