Description

Technical Field

[0001] The invention relates to the technical field of civil engineering structures, in particular to a filled friction pendulum seismic isolation support. Background Art

[0002] The friction pendulum isolation bearing is a bearing with a high seismic isolation effect. Its basic principle is: under the action of an earthquake, the upper and lower bearing plates of the bearing will slide relative to each other, and the convex spherical surface of the slider and the concave spherical surface of the bearing plate will slide and frictionally consume energy, thereby consuming seismic energy. When the friction pendulum isolation bearing is used in high-rise buildings or large transformer equipment, the upper structure will generate a huge overturning moment under horizontal action, which will convert the pressure on part of the bearing into tension. Therefore, the friction pendulum isolation bearing must be equipped with anti-pullout and anti-overturning measures before it can be used in engineering.

[0003] The pull-out resistance measures need to satisfy the requirement of limiting both the vertical displacement of the bearing and the horizontal displacement of the bearing, so a certain connection mechanism needs to be set to achieve this. At present, the connection mechanism used in the pull-out resistance measures of the friction pendulum isolation bearing is mainly a slide groove mechanism. However, the friction of the slide mechanism often leads to an unconstrained state in the horizontal direction that is not completely ideal, which has a great impact on the horizontal seismic isolation performance of the bearing. At the same time, the processing accuracy of the slide is extremely high. Insufficient processing accuracy or metal corrosion during use will seriously affect its sliding ability, and then affect the energy consumption capacity of the bearing. In addition, in order to achieve vertical shock absorption, the common friction pendulum seismic isolation bearing is usually provided with a disc spring group, and a viscous liquid damper is arranged in the space inside the disc spring. However, most of them use a single disc spring group. The vertical bearing capacity of this spring group is relatively small, and the viscous liquid damper in the closed container is located in the closed container in the middle of the disc spring. It relies on the compression of the liquid volume to provide a small vertical deformation. After loading, the oil pressure in the container is relatively large, and the vertical deformation capacity of the bearing is limited. In addition, the sliding friction surface on the bearing plate in the common friction pendulum seismic isolation bearing needs to be cut and processed from solid steel. On the one hand, the cutting amount is large, the processing difficulty and cost are high, especially for spherical surfaces with larger size and depth. On the other hand, the solid steel components are heavy and difficult to transport and install. Summary of the invention

[0004] The object of the present invention is to provide a filled friction pendulum isolation bearing to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a filled friction pendulum seismic isolation bearing, comprising an upper bearing plate, a lower bearing plate and a double spherical slider, wherein an upper friction plate is arranged at the bottom of the upper bearing plate, a lower friction plate is arranged at the top of the lower bearing plate, friction surfaces are arranged at the top and bottom of the double spherical slider, a vertical buffer seat is arranged at the top of the upper bearing plate, and a plurality of evenly distributed disc spring mechanisms are arranged between the vertical buffer seat and the upper bearing plate, wherein the disc spring mechanism comprises connecting bolts and a set of two disc spring mechanisms. A buffer disc spring is arranged on the outside of the connecting bolt, and a plurality of connecting rod mechanisms are arranged on the peripheral side of the vertical buffer seat, and the connecting rod mechanisms include connecting rod one and connecting rod two which are hinged to each other and a connecting shaft arranged at the ends of the two connecting rods. An expansion seat is fixedly installed on the peripheral side of the lower support plate, and a slip ring is slidably installed inside the expansion seat, and a plurality of damping holes are opened on the slip ring. A sealing cover is fixedly installed on the top of the expansion seat and the lower support plate, and the connecting shaft passes through the sealing cover and is threadedly connected to the slip ring, and the interior of the expansion seat is filled with viscous liquid.

[0006] Preferably, the upper support plate and the lower support plate are prepared by welding the two end faces and the circumferential rings, the interiors of the upper support plate and the lower support plate are hollow structures, the interiors of the upper support plate are welded with an upper support skeleton that cooperates with the upper friction plate, and the interiors of the lower support plate are welded with a lower support skeleton that cooperates with the lower friction plate. By respectively arranging the upper support skeleton and the lower friction plate inside the upper support plate and the lower support plate, the upper friction plate and the lower friction plate can be auxiliary supported, so that the upper support plate and the lower support plate can obtain a structural strength close to that of solid steel.

[0007] Preferably, the upper friction plate is fixedly mounted on the upper support plate by screws, and the lower friction plate is fixedly mounted on the lower support plate by screws. The interiors of the upper support plate and the lower support plate are both filled with concrete. When the concrete solidifies, the upper support plate and the lower support plate obtain a structural strength close to that of solid steel.

[0008] Preferably, the connecting bolt is passed through the top of the upper support plate, and the top end of the connecting bolt is threadedly connected to the inner side of the top of the vertical buffer seat, and the buffer disc springs outside the connecting bolt are located on the inner and outer sides of the top of the upper support plate in the same number, and the vertical buffer seat and the upper support plate are connected as a whole through the connecting bolt, ensuring that the vertical buffer seat and the upper support plate can move synchronously in the horizontal direction, while realizing the vertical direction restriction of the upper support plate through the vertical buffer seat.

The connecting rod mechanism cooperates with the slip ring to limit the relative position between the upper support plate and the upper friction plate, thereby improving the pull-out resistance of the support.

[0010] Preferably, a plurality of guide rods are fixedly installed on the bottom of the inner side of the expansion seat, the slip ring is movably sleeved on the outside of the guide rod, the outer movably sleeve of the guide rod is provided with a compression spring, and the outer fixed sleeve of the slip ring is provided with a sealing ring. By providing the sealing ring, the sealing between the slip ring and the inner wall of the expansion seat is improved to ensure that the viscous liquid can only flow along the damping hole when the slip ring slides, thereby ensuring the energy dissipation effect in the vertical direction.

The sealing film is a weather-resistant rubber film, which seals the upper support plate and the lower support plate to prevent foreign matter from invading the friction surface of the support and causing the support to fail, thereby improving the weather resistance of the support.

At the same time, the connecting rod mechanism cooperates with the slip ring to limit the relative position between the upper bearing plate and the upper friction plate, thereby improving the bearing's anti-pullout performance.

[0016] 2. The filled friction pendulum seismic isolation bearing, by combining a plurality of disc spring mechanisms between the vertical buffer seat and the upper bearing plate, and arranging an expansion seat and a slip ring cooperating with the connecting rod mechanism on the peripheral side of the lower bearing plate, utilizes the principle of a viscous liquid damper and combines a plurality of disc spring mechanisms to improve the energy dissipation capacity of the bearing during vertical deformation. Meanwhile, disc springs are arranged on the upper and lower sides of the top of the upper bearing plate, and the slip ring can slide up and down inside the expansion seat, thereby ensuring that the bearing can effectively dissipate energy when moving upward or downward.

[0017] 3. The filled friction pendulum seismic isolation bearing makes the upper bearing plate and the lower bearing plate hollow, and the components of the upper bearing plate and the lower bearing plate can be assembled by welding.

[0030] See also Figures 1 to 10In the embodiment of the present invention, a filled friction pendulum seismic isolation bearing comprises an upper bearing plate 1, a lower bearing plate 4 and a double spherical slider 7. An upper friction plate 2 is arranged at the bottom of the upper bearing plate 1, and a lower friction plate 5 is arranged at the top of the lower bearing plate 4. The upper bearing plate 1 and the lower bearing plate 4 can be welded together. Compared with the previous solid steel cutting, the processing difficulty and cost of the upper bearing plate 1 and the lower bearing plate 4 can be reduced. The top and bottom of the double spherical slider 7 are both provided with friction surfaces 8. The top of the upper bearing plate 1 is provided with a vertical buffer seat 9. , and a plurality of evenly distributed disc spring mechanisms 11 are arranged between the vertical buffer seat 9 and the upper support plate 1, the disc spring mechanism 11 includes a connecting bolt 111 and a set of buffer disc springs 112 mounted on the outside of the connecting bolt 111, and disc springs are arranged on the upper and lower sides of the top of the upper support plate 1, and the slip ring 13 can slide up and down inside the expansion seat 12 to ensure that the support can effectively dissipate energy when moving up or down, and a plurality of connecting rod mechanisms 10 are arranged on the peripheral side of the vertical buffer seat 9, and the connecting rod mechanism 10 includes a connecting rod 1 101, a connecting rod 2 102 and a connecting rod 3 103 which are hinged to each other. 02 and a connecting shaft 103 arranged at the end of the second connecting rod 102, a plurality of connecting rod mechanisms 10 are arranged around the vertical buffer seat 9 at the top of the upper support plate 1 to replace the previous slide groove mechanism, so as to limit the vertical direction of the support and ensure the ability of the support to dissipate energy by horizontal sliding. An expansion seat 12 is fixedly installed around the lower support plate 4, and a slip ring 13 is slidably installed inside the expansion seat 12, and a plurality of damping holes 15 are opened on the slip ring 13. A sealing cover 18 is fixedly installed on the top of the expansion seat 12 and the lower support plate 4, and the connecting shaft 10 3 passes through the sealing cover 18 and is threadedly connected with the slip ring 13. The connecting rod mechanism 10 cooperates with the slip ring 13 to limit the relative position between the upper support plate 1 and the upper friction plate 2, thereby improving the pull-out resistance of the support. The interior of the expansion seat 12 is filled with viscous liquid. By using the principle of viscous liquid damper, when the vertical buffer seat 9 pulls the slip ring 13 to move upward or downward in the expansion seat 12 through the connecting rod mechanism 10, the viscous liquid in the expansion seat 12 reciprocates through the damping hole 15 to generate a damping force, thereby realizing energy consumption of vertical vibration.

[0031] As a further implementation scheme of the above invention: the upper support plate 1 and the lower support plate 4 are both prepared by welding the two end faces and the circumferential rings. The components of the upper support plate 1 and the lower support plate 4 are welded together. Compared with the previous cutting of solid steel, the processing difficulty and cost of the upper support plate 1 and the lower support plate 4 can be reduced, and the transportation difficulty can be reduced. The upper support plate 1 and the lower support plate 4 are both hollow structures. The upper support plate 1 has an upper support skeleton 3 welded inside to match the upper friction plate 2, and the lower support plate 4 has a lower support skeleton 6 welded inside to match the lower friction plate 5. By respectively arranging the upper support skeleton 3 and the lower friction plate 5 inside the upper support plate 1 and the lower support plate 4, the upper friction plate 2 and the lower friction plate 5 can be auxiliary supported, so that the upper support plate 1 and the lower support plate 4 can obtain a structural strength close to that of solid steel.

[0032] As a further implementation scheme of the above invention: the upper friction plate 2 is fixedly installed on the upper support plate 1 by screws, and the lower friction plate 5 is fixedly installed on the lower support plate 4 by screws. The upper friction plate 2 and the lower friction plate 5 are installed by bolt connection to ensure their firmness after installation and facilitate disassembly and assembly. The interiors of the upper support plate 1 and the lower support plate 4 are filled with concrete. When the concrete is cured, the upper support plate 1 and the lower support plate 4 obtain a structural strength close to that of solid steel.

[0033] As a further implementation scheme of the above invention: a connecting bolt 111 is passed through the top of the upper support plate 1, and the top end of the connecting bolt 111 is threadedly connected to the inner side of the top of the vertical buffer seat 9, ensuring that the vertical buffer seat 9 and the upper support plate 1 can be connected as a whole through the connecting bolt 111, ensuring that the vertical buffer seat 9 and the upper support plate 1 can move synchronously in the horizontal direction, and at the same time, the vertical direction of the upper support plate 1 is restricted by the vertical buffer seat 9. The buffer disc springs 112 outside the connecting bolt 111 are located on the inner and outer sides of the top of the upper support plate 1 in the same number. When the vertical buffer seat 9 vibrates upward or downward, the buffer disc springs 112 on the corresponding side can effectively dissipate energy.

[0034] As a further implementation scheme of the above invention: connecting rod 101 and connecting rod 2 102 are both arranged horizontally, and the end of connecting rod 101 away from connecting rod 2 102 is hinged to the peripheral side of the vertical buffer seat 9, and a plurality of connecting rod mechanisms 10 are arranged on the peripheral side of the vertical buffer seat 9 at the top of the upper support plate 1 to replace the previous slide groove mechanism, so as to achieve vertical direction restriction of the support while ensuring the ability of the support to dissipate energy by horizontal sliding. The connecting shaft 103 is vertically threadedly connected to the end of connecting rod 2 102 away from connecting rod 1 101. The connecting rod mechanism 10 cooperates with the slip ring 13 to limit the relative position between the upper support plate 1 and the upper friction plate 2, thereby improving the pull-out resistance of the support.

[0035] As a further implementation scheme of the above invention: a plurality of guide rods 16 are fixedly installed on the bottom of the inner side of the expansion seat 12, and the slip ring 13 is movably sleeved on the outside of the guide rods 16. The guide rods 16 are used to limit the slip ring 13 to ensure the stability of the slip ring 13 when it slides inside the expansion seat 12. The outer movably sleeve of the guide rod 16 is provided with a compression spring 17. The compression spring 17 on the outside of the guide rod 16 applies elastic force to the slip ring 13 to facilitate the resetting of the slip ring 13. The outer fixed sleeve of the slip ring 13 is provided with a sealing ring 14. The sealing between the slip ring 13 and the inner wall of the expansion seat 12 is improved by setting the sealing ring 14, so as to ensure that the viscous liquid can only flow along the damping hole 15 when the slip ring 13 slides, thereby ensuring the energy dissipation effect in the vertical direction.

[0036] As a further implementation scheme of the above invention: a through hole cooperating with the connecting shaft 103 is opened on the sealing cover 18, and the sealing cover 18 can seal the top of the expansion seat 12 to prevent the viscous liquid inside the expansion seat 12 from leaking. The external movable sleeve of the connecting shaft 103 is equipped with a compression spring 17 located inside the expansion seat 12. The compression spring 17 outside the expansion seat 12 applies elastic force to the slip ring 13 to facilitate the resetting of the slip ring 13.

[0037] As a further implementation scheme of the above invention: the viscous liquid is damping oil or damping grease, the number of damping holes 15 is 4-20 groups, and the diameter of the damping holes 15 is 1-10mm. When the vertical buffer seat 9 pulls the slip ring 13 to move upward or downward in the expansion seat 12 through the connecting rod mechanism 10, the viscous liquid in the expansion seat 12 flows back and forth through the damping hole 15 to generate a damping force, thereby dissipating energy for vertical vibration.

[0038] As a further implementation scheme of the above invention: a sealing film 19 is glued to the bottom of the upper support plate 1, and the bottom of the sealing film 19 is against the sealing cover 18. The sealing film 19 is a weather-resistant rubber film, which seals the upper support plate 1 and the lower support plate 4 to prevent foreign matter from invading the friction surface of the support and causing the support to fail, thereby improving the weather resistance of the support.

[0039] During specific implementation: after the support is installed on a building or equipment, when horizontal vibration occurs, the vertical buffer seat 9 drives the upper support plate 1 to move in the horizontal direction, and pushes the double spherical slider 7 to move on the top of the lower support plate 4, and friction energy is consumed between the friction surfaces 8 at the top and bottom of the double spherical slider 7 and the upper friction plate 2 at the bottom of the upper support plate 1 and the lower friction plate 5 at the top of the lower support plate 4. At the same time, when the vertical buffer seat 9 moves in the horizontal direction, the vertical buffer seat 9 can pull the connecting rod 1 101 and the connecting rod 2 102 in the peripheral link mechanism 10 to perform adaptive expansion and contraction. Since the connecting shaft 103 is threadedly connected to the slip ring 13 , the vertical buffer seat 9 and the upper support plate 1 are restricted by a plurality of connecting rod mechanisms 10, so that the vertical buffer seat 9 and the upper support plate 1 can move freely in the horizontal direction, and at the same time improve the pull-out resistance of the vertical buffer seat 9 and the connecting rod mechanism 10; when the upper support plate 1 moves in the horizontal direction, the upper support plate 1 drives the sealing film 19 at the bottom to move synchronously, and the upper support plate 1 and the lower support plate 4 are sealed by the sealing film 19 to prevent foreign matter from invading the friction surface of the support and causing the support to fail; when vertical vibration occurs, the vertical buffer seat 9 moves upward or downward, and the inner or outer side of the top of the upper support plate 1 The buffer disc spring 112 is compressed, and energy is consumed by the friction between the buffer disc springs 112. At the same time, the vertical buffer seat 9 drives the connecting rod 101, the connecting rod 2 102 and the connecting shaft 103 to move upward or downward synchronously when moving. The connecting shaft 103 pulls the slip ring 13 to move upward or downward in the expansion seat 12. The viscous liquid in the expansion seat 12 reciprocates through the damping hole 15 to generate a damping force, which again consumes energy for the vertical vibration. The buffer disc springs 112 are arranged on the upper and lower sides of the top of the upper support plate 1, and the slip ring 13 can slide up and down inside the expansion seat 12 to ensure that the support can move upward or downward. Effective energy consumption; the upper support plate 1 and the lower support plate 4 are both prepared by welding the two end faces and the circumferential ring together. Compared with the previous method of cutting solid steel, the processing difficulty and cost of the upper support plate 1 and the lower support plate 4 are reduced. The upper support plate 1 and the lower support plate 4 are hollow structures. After the upper support frame 3 and the lower support frame 6 are welded in place, concrete is filled inside the upper support plate 1 and the lower support plate 4. After the concrete solidifies, the upper support plate 1 and the lower support plate 4 can obtain a structural strength close to that of solid steel. When filling the upper support plate 1 with concrete, a placement space for cooperating with the disc spring mechanism 11 is reserved on the upper support frame 3.
