Description

Technical Field

[0001] The utility model relates to the technical field of building structure seismic isolation, in particular to a stainless steel plate inlaid cylindrical friction pendulum support. Background Art

[0002] The cylindrical friction pendulum bearing is an important component of modern bridges and building structures. It not only transfers the load of the upper part of the structure to the lower structure, but also provides corresponding rotation and displacement for the upper structure. It should also have a certain seismic isolation effect. The main principle of the friction pendulum system is to isolate the bridge or grid structure itself from the ground, use the design period of the friction pendulum to extend the natural vibration period of the structure, reduce the dynamic amplification effect caused by vibration, convert kinetic energy into potential energy and heat energy, and effectively transfer and consume vibration energy.

[0003] The existing friction pendulum usually consists of an upper support, a lower support, a slider and a spherical lining. The vibration period of the building is extended by sliding the slider on the spherical surface, and the vibration energy is dissipated by friction. However, the existing friction pendulum support is usually welded, and the components of the support are prone to cause gaps between the support and the stainless steel plate due to insufficient squeezing during the welding process. Therefore, after welding, the stainless steel plate needs to be rolled and emptied, which makes the stainless steel plate prone to wear, thereby affecting the friction coefficient of the stainless steel plate and reducing the service life of the stainless steel plate. Therefore, a stainless steel plate inlaid cylindrical friction pendulum support is proposed to solve the above problems. Utility Model Content

[0009] Furthermore, the anti-collision component includes a rubber pad, which is fixedly connected to the outer side of the buffer plate, and the middle of the rubber pad is slidably connected with bolt 2, which penetrates the rubber pad and is threadedly connected to the middle of the buffer plate.

[0010] Furthermore, a mounting seat is fixedly connected to the outer side of the lower support.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1-3 The utility model provides an embodiment: a stainless steel plate inlaid cylindrical friction pendulum support, including a lower support 1 and an upper support 2, the outer side of the lower support 1 is fixedly connected with a mounting seat 5, the middle of the lower support 1 and the upper support 2 are slidably connected with an arc-shaped stainless steel plate 12, the middle of the lower support 1 and the upper support 2 are both provided with a positioning groove 18, the arc-shaped stainless steel plate 12 is slidably connected in the middle of the positioning groove 18, and the lower support 1 and the upper support 2 are both provided with a pressing edge 3 on the opposite side. A block 17 is fixedly connected to the middle of 3, a slot 16 is provided in the middle of the lower support 1 and the upper support 2, the block 17 is slidably connected to the middle of the slot 16, the block 17 and the slot 16 are both conical, a bolt 6 is slidably connected to the middle of the pressure edge 3, a through hole 19 is provided in the middle of the pressure edge 3, the bolt 6 is slidably connected to the middle of the through hole 19, a threaded hole 4 is provided in the middle of the lower support 1 and the upper support 2, the bolt 6 penetrates the pressure edge 3 and is threadedly connected to the middle of the threaded hole 4.

[0024] When in use, under the action of the conical clamping block 17, the edge clamping 3 can be quickly engaged with the lower support 1, so as to align the threaded hole 4 with the through hole 19, so that the bolt 6 can quickly connect the edge clamping 3 with the lower support 1, and as the bolt 6 is tightened, the edge clamping 3 will gradually increase the extrusion force on the arc-shaped stainless steel plate 12 in the lower support 1, thereby reducing the gap between the arc-shaped stainless steel plate 12 and the lower support 1, and there is no need to roll and empty the arc-shaped stainless steel plate 12, thereby improving the integrity of the arc-shaped stainless steel plate 12, so as to ensure the friction coefficient and service life of the arc-shaped stainless steel plate 12 during use. The installation steps of the upper support 2 are the same as those of the lower support 1.

[0025] Reference Figure 1-3 A slider 11 is slidably connected to the middle of the lower support 1 and the upper support 2, a spherical lining 13 is installed on the opposite side of the two sliders 11, and a resistance assembly is installed on the opposite side of the two sliders 11. The resistance assembly includes a plurality of bolts 14, and the plurality of bolts 14 are respectively threadedly connected to the middle of the two sliders 11, and polytetrafluoroethylene plates 15 are respectively slidably connected to the outer peripheries of the plurality of bolts 14.

[0026] When in use, when the lower support 1 and the upper support 2 slide under the vibration force, the slider 11 and the arc-shaped stainless steel plate 12 will be driven to rub against each other, so as to dissipate the vibration energy under the action of friction force, and at the same time reduce the damage caused by friction under the action of the polytetrafluoroethylene plate 15.

[0027] Reference Figure 1 and 2 The middle part of the pressure edge 3 is fixedly connected with a limiting rod 10, the outer side of the pressure edge 3 is fixedly connected with a buffer plate 7, the outer side of the buffer plate 7 is installed with an anti-collision component, the anti-collision component includes a rubber pad 8, the rubber pad 8 is fixedly connected to the outer side of the buffer plate 7, the middle part of the rubber pad 8 is slidably connected with a bolt 2 9, the bolt 2 9 penetrates the rubber pad 8 and is threadedly connected to the middle part of the buffer plate 7.

[0028] When in use, the lower support 1 and the upper support 2 will drive the limit rod 10 to move together when sliding, so that after the lower support 1 and the upper support 2 slide to a certain extent, the limit rod 10 will prevent the lower support 1 and the upper support 2 from continuing to slide, so as to avoid the lower support 1 and the upper support 2 from separating due to excessive sliding amplitude. At the same time, the limit rod 10 can be blocked by the action of the buffer plate 7 and the rubber pad 8 to avoid the limit rod 10 colliding with the pressure edge 3 during sliding, thereby improving the service life of the limit rod 10.

[0029] Working principle: first, align the block 17 on the edge clamp 3 with the slot 16 on the lower support 1 and insert it, so that the edge clamp 3 can be quickly positioned on the lower support 1, so that the bolt 6 can pass through the through hole 19 and align with the threaded hole 4, thereby increasing the connection speed of the bolt 6, so that the arc-shaped stainless steel plate 12 can be squeezed by the edge clamp 3 as the bolt 6 is tightened, thereby being fixed between the lower support 1 and the edge clamp 3, so as to reduce the gap between the edge clamp 3 and the lower support 1 under a larger extrusion pressure, thereby avoiding emptying, reducing the wear of the arc-shaped stainless steel plate 12, and ensuring the friction coefficient and service life. The installation method of the upper support 2 and the arc-shaped stainless steel plate 12 is the same as above.

[0030] The upper support 2 will drive the limit rod 10 to move together during the movement, so as to ensure the stability of the upper support 2 during the movement and avoid the lower support 1 and the upper support 2 being separated due to excessive sliding. At the same time, the impact force caused by the limit rod 10 can be absorbed by the buffer plate 7 and the rubber pad 8, thereby avoiding the limit rod 10 colliding with the pressure edge 3 and causing damage.
