Description

Technical Field

[0001] The utility model relates to the technical field of bridges and building structures, and in particular to a replaceable seismic isolation support of an energy dissipation device. Background Art

[0002] In the past few decades, my country's rapid economic growth is inseparable from the rapid development of highway and railway bridge technology. However, my country is located between the Pacific Rim and the Eurasian seismic belt, and is a country with serious earthquake disasters. The impact of earthquakes far exceeds that of other natural disasters. The direct losses caused by the collapse of bridges due to earthquakes and the indirect losses caused by the resulting traffic paralysis are very huge. Among the various seismic design methods for railway bridges, seismic isolation design has been proven to be the most economical and effective method through engineering practice. This method generally guides the damage form of the structure purposefully and improves the seismic performance of the overall structure by installing bearings with seismic isolation functions between the upper and lower structures. At present, the seismic isolation bearings used in the field of bridge seismic resistance mainly include rubber bearings, lead rubber bearings, sliding friction type seismic isolation bearings, elastic-plastic shock-absorbing energy-absorbing steel dampers, magnetorheological dampers, and oil dampers.

[0003] Traditional spherical steel seismic isolation bearings mostly adopt a "hard-on-hard" approach, that is, a limit device is set. When the seismic force is small, the limit device does not consume energy and only plays a limiting role. When the seismic force is large, the limit device is sheared off to dissipate the seismic energy; or the device "dissipates energy" to reduce or offset the seismic response to prevent the structure from entering plasticity too early; or an auxiliary energy dissipation device, such as a circular steel, is set on the bearing body to dissipate seismic energy through the deformation of the steel component to reduce the seismic response. However, with the increase in the seismic intensity in the area where the bridge is located and the increase in the weight of the beam at the bearing, the service life of the energy dissipation device is gradually shortened, so it needs to be replaced frequently. However, in the current design, the energy dissipation device and the seismic isolation bearing adopt the traditional connection method, which makes it difficult to replace the energy dissipation device or requires the entire bearing to be replaced, resulting in resource waste and increased engineering costs. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a seismic isolation bearing with replaceable energy absorbing device. One or more rotating energy absorbing devices are arranged between the upper seat plate and the lower seat plate of the bearing, which can not only meet the displacement requirements of the bridge under the action of temperature, shrinkage creep, and vehicle load under normal circumstances, but also dissipate seismic energy through plastic deformation of the energy absorbing device. When the seismic force exceeds the bearing value of the energy absorbing device, the energy absorbing device undergoes plastic deformation, but the device does not "disintegrate" to avoid the occurrence of falling beams. After the earthquake, only the energy absorbing device needs to be replaced. At the same time, each part of the device can be disassembled separately, which is convenient for the replacement and maintenance of the energy absorbing device during its normal service life.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A support, comprising an upper seat plate, a middle seat plate and a lower seat plate arranged in sequence from top to bottom, specifically, an energy dissipation structure is arranged on at least one side of the support, and the energy dissipation structure comprises a first force transmission guide plate, an energy dissipation device and a second force transmission guide plate connected in sequence, the first force transmission guide plate is rotatably connected to one of the upper seat plate and the lower seat plate at an end away from the energy dissipation device, and the second force transmission guide plate is rotatably connected to the other of the upper seat plate and the lower seat plate at an end away from the energy dissipation device. The support provided by the utility model can not only meet the displacement requirements of the main beam under loads such as temperature, shrinkage creep, and vehicle braking force under normal circumstances, but also absorb earthquake energy through plastic deformation of the energy dissipation device between the upper seat plate and the lower seat plate when an earthquake occurs, thereby minimizing damage to the bridge.

[0007] Preferably, there are multiple energy dissipation structures and they are symmetrically arranged on both sides of the upper seat plate. Such an arrangement can make both sides of the support evenly stressed and prevent the bridge deck from tilting.

[0008] Preferably, the first force transmission guide plate is arranged higher than the lowest point of the upper seat plate, and the second force transmission guide plate is arranged lower than the lowest point of the upper seat plate. This arrangement enables the force transmission guide plate to produce a small range of torsion to balance the displacement produced by the bridge.

[0009] Preferably, the energy dissipation structure further comprises a connecting U-shaped piece, which is fixedly arranged on the upper seat plate or the lower seat plate by a support connecting bolt, and is used for rotating and assembling the first force transmission guide plate or the second force transmission guide plate. This arrangement can increase the stability of the connection between the energy dissipation structure and the support, and facilitate the replacement of the energy dissipation structure.

[0010] Preferably, the energy dissipation device is a tubular structure, including a circular connecting plate and an energy dissipation pipe that are reliably connected. An assembly hole is set in the middle of the circular connecting plate, and the energy dissipation pipe is vertically fixed in the assembly hole; the circular connecting plate is provided with an arc groove for clamping with the first force transmission guide plate and the second force transmission guide plate; the arc length of the arc groove is L = nπR / 180, where n is the central angle of the designed rotation, and R is the radius of the circular connecting plate. This setting not only facilitates the separate disassembly and replacement of the various parts of the energy dissipation structure, but also enhances the shock absorption and seismic isolation effect of the support.

[0011] Preferably, the first force transmission guide plate and / or the second force transmission guide plate comprises an A end and a B end, the A end is provided with a circular boss, the middle of the circular boss is hollow to form a through hole, and the B end is provided with an arcuate boss corresponding to the arcuate groove. In a specific embodiment of the present invention, the B end is also provided with a through hole;

[0012] The A ends of the first force transmission guide plate and the second force transmission guide plate are respectively fixedly connected to the connecting U-shaped member through a fastening device, and the fastening device is a detachable fixing device;

[0013] The B ends of the first force transmission guide plate and the second force transmission guide plate are connected to the energy dissipation device through high-strength bolts, and the high-strength bolts pass through the first force transmission guide plate, the energy dissipation device, and the second force transmission guide plate in sequence and are then locked by tightening nuts;

[0014] The through holes at the A end and the B end are respectively used to accommodate the fastening device and the high-strength bolts. The arc-shaped boss of the force transmission guide plate can be snapped into the arc-shaped groove of the energy-absorbing device. Therefore, when the seismic force borne by the bearing exceeds the set capacity value, the energy-absorbing device is sheared off. However, due to the presence of the fastening device and the high-strength bolts on the energy-absorbing structure, the upper and lower seat plates of the bearing are still "connected" as a whole, so it can play the function of preventing the beam from falling.

[0015] Preferably, a spherical friction pair is arranged between the upper seat plate and the middle seat plate, and between the middle seat plate and the lower seat plate, and the spherical friction pair includes a spherical stainless steel slide plate and a spherical polytetrafluoroethylene slide plate, and the spherical stainless steel slide plate and the spherical polytetrafluoroethylene slide plate are stacked on a horizontal plane. This arrangement enables the bearing to perform hysteresis motion in any direction, and the friction resistance of the sliding surface achieves the seismic isolation effect on the bridge under normal circumstances.

[0016] Preferably, a guide friction pair is arranged between the upper seat plate and the lower seat plate, and the guide friction pair comprises a guide stainless steel slide plate and a guide polytetrafluoroethylene slide plate, and the guide stainless steel slide plate and the guide polytetrafluoroethylene slide plate are placed vertically. The guide friction pair is responsible for transmitting the vertical force of the support and has a seismic isolation effect on the bridge.

[0017] Compared with the prior art, the replaceable seismic isolation bearing of the energy-absorbing device described in the utility model has the following advantages: 1) The bearing described in the utility model is a hyperbolic bearing which can not only rotate normally and slide horizontally, but also has three sets of friction pairs which give the bearing a seismic isolation function. Under normal circumstances, it can meet the displacement requirements of the beam under loads such as temperature, shrinkage creep, and vehicle braking force.

[0018] 2) The support described in the utility model is connected with an energy-absorbing structure. When an earthquake occurs, the force transmission guide plate produces relative displacement, which drives the energy-absorbing device to twist, causing the energy-absorbing device to undergo plastic deformation to absorb earthquake energy. When the energy-absorbing device is sheared off, due to the presence of connecting bolts, the upper and lower seat plates of the support are still connected as a whole, avoiding the occurrence of falling beams, and having high use value.

[0019] 3) The utility model has a simple structure and is easy to manufacture and install. The support and the energy-consuming structure, as well as the components of the energy-consuming structure, are connected by bolts. When the energy-consuming structure is deformed or damaged, only the energy-consuming structure needs to be replaced. At the same time, each part of the energy-consuming structure can be disassembled separately, which is convenient for replacement and maintenance of the energy-consuming structure during its normal service life, and has low maintenance costs.

It should be noted that the technical features in the embodiments of the utility model can be combined with each other without conflict.

[0035] Example 1

[0036] like Figure 1-Figure 7 As shown, a seismic isolation support with replaceable energy dissipation device is composed of a seismic isolation support and an energy dissipation structure. The seismic isolation support includes an upper seat plate 1, a sealing ring 2, a spherical stainless steel slide plate 3, a spherical polytetrafluoroethylene slide plate 4, a middle seat plate 5, a guide stainless steel slide plate 6, a guide polytetrafluoroethylene slide plate 7 and a lower seat plate 8.

[0037] The upper part of the upper seat plate 1 is a plane, and the lower part is embedded with a cylindrical surface. The surface of the lower center that fits with the middle seat plate 5 is a concave spherical surface, and a spherical stainless steel slide plate 3 is welded on the concave spherical surface; the upper and lower surfaces of the middle seat plate 5 are convex spherical surfaces, and a sealing ring 2 and a spherical PTFE slide plate 4 are arranged on the convex spherical surface. The sealing ring 2 is arranged horizontally around the spherical PTFE slide plate 4 to prevent dust from entering the gap between the upper seat plate 1 and the middle seat plate 5; the surface of the upper center of the lower seat plate 8 that fits with the middle seat plate 5 is a concave spherical surface, and a spherical stainless steel slide plate 3 is welded on the concave spherical surface. The middle seat plate 5 is arranged in the space surrounded by the upper seat plate 1 and the lower seat plate 8, and the diameter of the enclosed space is slightly larger than the diameter of the middle seat plate 5. The convex spherical surface of the middle seat plate 5 cooperates with the concave spherical surfaces of the upper seat plate 1 and the lower seat plate 8 to realize the rotation of the support.

[0038] The spherical stainless steel slide plate 3 of the concave surface of the upper seat plate 1 and the spherical polytetrafluoroethylene slide plate 4 on the upper surface of the middle seat plate 5 constitute an upper spherical friction pair; the spherical stainless steel slide plate 3 of the concave surface of the lower seat plate 8 and the spherical polytetrafluoroethylene slide plate 4 on the lower surface of the middle seat plate 5 constitute a lower spherical friction pair. Both the upper spherical friction pair and the lower spherical friction pair are sliding friction pairs, and the two sliding friction pairs jointly bear the rotation of the support and the curved surface sliding under earthquake.

[0039] Furthermore, the length of the upper end of the lower seat plate 8 is greater than that of the lower end, and a guide polytetrafluoroethylene slide plate 7 is provided on the side of the upper end, and the guide polytetrafluoroethylene slide plate 7 is vertically placed on the side of the lower seat plate 8 and partially embedded in the upper end of the lower seat plate 8. The surface of the lower end of the upper seat plate 1 connected to the lower seat plate 8 is provided with a guide stainless steel slide plate 6, and the guide stainless steel slide plate 6 is vertically placed on the side of the upper seat plate 1. The guide stainless steel slide plate 6 and the guide polytetrafluoroethylene slide plate 7 constitute a guide friction pair, and the guide friction pair bears the vertical force transmission function of the support.

[0040] The energy dissipation structure includes a connecting U-shaped part 9, a force transmission guide plate 10, a high-strength bolt 11, an energy dissipation device 12, a nut 13, a fastening device 14 and a support connecting bolt 15. The energy dissipation structure is connected to the support through the connecting U-shaped part 9 and the support connecting bolt 15. There are two connecting U-shaped parts 9, including a first connecting U-shaped part and a second connecting U-shaped part, and the first connecting U-shaped part and the second connecting U-shaped part are respectively located at the two ends of the support, and there is a height difference. Specifically, the upper seat plate 1 and the first connecting U-shaped part are fixedly connected with the support connecting bolt 15, and the lower seat plate 8 and the second connecting U-shaped part are fixedly connected with the support connecting bolt 15, the first connecting U-shaped part is located at the left end of the upper seat plate 1, and the second connecting U-shaped part is located at the right end of the lower seat plate 8, or the first connecting U-shaped part is located at the right end of the upper seat plate 1, and the second connecting U-shaped part is located at the left end of the lower seat plate 8.

[0041] The force transmission guide plate 10 is divided into an A end and a B end. The A end is provided with a circular boss 101. The circular boss 101 is hollow in the middle to form a through hole 102 for accommodating the fastening device 14. The B end is provided with an arc-shaped boss 103. Specifically, the force transmission guide plate 10 includes a first force transmission guide plate and a second force transmission guide plate. The first connecting U-shaped member and the A end of the first force transmission guide plate, and the second connecting U-shaped member and the A end of the second force transmission guide plate are connected and fixed by the fastening device 14. The fastening device 14 is a detachable fixing device, including a bolt or a pin, which can ensure that after the force transmission guide plate 10 is connected to the connecting U-shaped member 9, the A end of the force transmission guide plate 10 can rotate normally.

[0042] The energy dissipation device 12 is a tubular structure, including a circular connecting plate 121 at the end and an energy dissipation pipe 122. The circular connecting plate 121 has two, including an upper circular connecting plate and a lower circular connecting plate. The energy dissipation pipe 122 is reliably connected to the circular connecting plate 121, and the reliable connection includes integrated molding or welding. The circular connecting plate 121 is provided with an arc groove 123, and the arc boss 103 at the end of the force transmission guide plate 10B can be snapped into the arc groove 123.

[0043] As an example of the present invention, the energy dissipation device 12 is located between the first connecting U-shaped member and the second connecting U-shaped member. Specifically, the upper circular connecting plate of the energy dissipation device 12 is connected to the B end of the force transmission guide plate 10, and the A end of the force transmission guide plate 10 is connected to the first connecting U-shaped member; the lower circular connecting plate of the energy dissipation device 12 is connected to the B end of the force transmission guide plate 10, and the A end of the force transmission guide plate 10 is connected to the second connecting U-shaped member. The energy dissipation device 12 is connected to the B end of the force transmission guide plate 10 through a high-strength bolt 11 and a fastening nut 13. The high-strength bolt 11 passes through the energy dissipation device 12 and is tightened and fixed by the fastening nut 13. The diameter of the high-strength bolt 11 is smaller than the inner diameter of the energy dissipation device 12, so that the high-strength bolt 11 can be installed normally.

[0044] As an example of the present invention, a curved non-metallic slide plate is fixedly embedded inside the curved groove 123 of the energy dissipation device 12. The radius of the curved boss 103 at the B end of the force transmission guide plate 10 is smaller than the radius of the curved groove 123, ensuring that the curved boss 103 at the B end of the force transmission guide plate 10 can rotate normally in the curved groove 123. Furthermore, silicone grease is applied to the surface of the curved non-metallic slide plate to improve the smoothness of the rotation of the curved boss 103.

[0045] The arc length of the arc groove 123 on the circular connecting plate 121 of the energy dissipation device 12 is calculated by the rotation angle allowed by the force transmission guide plate 10 when the beam body is deformed normally, specifically L=nπR / 180, where n is the central angle of the designed rotation, and R is the radius of the circular connecting plate. In this way, it can be ensured that in the case of an earthquake, the force transmission guide plate 10 can be "locked" with the energy dissipation device 12, so that the energy dissipation function of the energy dissipation device 12 can be realized normally.

[0046] Example 2

[0047] like Figure 6 , Figure 7 As shown, a parallel type seismic isolation bearing of an energy dissipation device is composed of two parts: a seismic isolation bearing and an energy dissipation structure. The seismic isolation bearing and the energy dissipation structure are as shown in Example 1 and will not be repeated here. In this embodiment, the energy dissipation structures are connected in parallel to form an energy dissipation structure group. During use, the number of energy dissipation structures can be increased or decreased according to actual needs.

[0048] The utility model provides a replaceable seismic isolation bearing with an energy dissipation device. Under normal use of the bridge, the rotation gap of the energy dissipation structure can meet the displacement requirements of the main beam under loads such as temperature, shrinkage creep, and vehicle braking force; when an earthquake occurs, the energy dissipation structure between the upper seat plate 1 and the lower seat plate 8 plays a role, and the relative displacement between the force transmission guide plate 10 drives the energy dissipation device 12 to twist, causing the energy dissipation device 12 to undergo plastic deformation to absorb earthquake energy. After the earthquake, since the various parts of the energy dissipation structure can be disassembled separately, only the energy dissipation device 12 needs to be replaced.

[0049] When the earthquake force borne by the bearing exceeds the set capacity value, the energy dissipation structure is sheared and destroyed, but due to the presence of high-strength bolts 11 on the energy dissipation device 12, the upper and lower seat plates of the bearing are still "connected" as a whole, so it can play the role of preventing the beam from falling. After the energy dissipation device 12 undergoes torsional plastic deformation, the force required for its reverse "recovery" to the original state is less than the force required for the energy dissipation device 12 to undergo torsional buckling deformation. At the same time, after the bearing undergoes horizontal displacement, the hyperbolic bearing has a certain restoring force, and thus the energy dissipation structure also has a certain "self-reset" function.

[0050] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
