Description

Technical Field

[0001] This utility model relates to the field of building energy dissipation and vibration reduction technology, specifically a wind-resistant friction pendulum support. Background Technology

[0002] Wind-resistant friction pendulum bearings are a type of seismic damping device used in building and bridge structures to reduce the impact of wind loads and seismic forces on the structure. With the development of seismic isolation and damping technology, people's understanding of new seismic isolation and damping technologies is constantly improving.

[0003] Chinese Utility Model Publication No. CN220704821U discloses a wind-resistant friction pendulum support, including a first seat plate and a second seat plate. Rectangularly arranged soft steel is provided between the first seat plate and the second seat plate. Stainless steel plates are provided inside both the first seat plate and the second seat plate. A sliding plate is slidably connected inside each stainless steel plate. A spherical crown liner is provided inside each sliding plate. The soft steel is fixedly connected to the first seat plate and the second seat plate by a fixing mechanism.

[0004] The device achieves the goal of resisting large wind loads, but it only relies on the resistance of the rubber pad itself for buffering, so its wind resistance is relatively weak. Moreover, because the rubber pad itself is relatively soft, its wind resistance will decrease after a period of use, so its practicality is not very good. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In the prior art, a wind-resistant friction pendulum support includes a seat plate 1 and a seat plate 2. A rectangular arrangement of soft steel 5 is provided between the seat plate 1 and the seat plate 2. Stainless steel plates are provided inside both the seat plate 1 and the seat plate 2. A sliding plate is slidably connected inside each stainless steel plate. A spherical crown liner is provided inside each sliding plate. This is the prior art and will not be elaborated on here.

[0024] Please see Figure 1-3 This utility model discloses a wind-resistant friction pendulum support. Both seat plate 1 and seat plate 2 are provided with sliding grooves 3. Sliding blocks 4 are slidably installed in the sliding grooves 3. Soft steel 5 is provided between several aligned sliding blocks 4. Under the action of external force, the soft steel 5 is stretched, causing the sliding blocks 4 to slide in the sliding grooves 3 of seat plate 1 and seat plate 2. A shock-absorbing component is fixedly installed at one end of the sliding block 4. An installation groove 6 is provided through the side wall of the sliding groove 3. One end of the shock-absorbing component is installed in the installation groove 6. Depending on the direction of the force on the sliding block 4, the shock-absorbing component is stretched or compressed, buffering the force on the sliding block 4 and playing a shock-absorbing role for the sliding block 4 and the soft steel 5.

[0025] The damping component includes a damper 7, which is a common device with good damping properties. There are many models available. The size, model, and shape of the damper 7 that meet the requirements can be selected according to the application scenario. A rubber pad 8 is installed through the telescopic end of the damper 7 and is fixedly set at one end of the slider 4. The rubber pad 8 is fixedly set at one end of the slider 4. The slider 4 compresses the rubber pad 8 while compressing the damper 7, thereby playing a certain role in buffering the force.

[0026] The slider 4 has several threaded holes, and bolts 9 are threaded into the threaded holes.

[0027] Both seat plate 1 and seat plate 2 are provided with several limiting grooves 10. Bolt 9 passes through the limiting groove 10 and is screwed into the threaded hole 1 of slider 4. It moves within the limiting groove 10. The overall length of the limiting groove 10 can limit the maximum position of the slider 4 in the sliding groove 3.

[0028] Both seat plate 1 and seat plate 2 have several through holes, and bolts 2 are installed through them. One end of bolt 2 is threaded with a stop block 11. Bolt 2 is passed through the through hole and then screwed into the stop block 11. The stop block 11 is installed at the groove opening of the slide groove 3 to block the slider 4.

[0029] A rubber pad 12 is provided on the side of the stop block 11 facing the slider 4. There is a displacement buffer space between the rubber pad 12 and the slider 4. When the slider 4 moves towards the groove under the pull of the soft steel 5, it presses against the rubber pad 12, and the rubber pad 12 contracts, thus playing a certain role in buffering the force.

[0030] In summary, in the application of a wind-resistant friction pendulum support, the damper 7, with its telescopic end selected according to the usage scenario and conforming to the size, model, and shape requirements, is installed through a rubber pad 8 and fixed at one end of the slider 4. Next, the other end of the damping component is installed into the mounting groove 6 that penetrates the side wall of the slide 3. The sliders 4 are then slidably installed into the slide 3 of the seat plate 1 and seat plate 2, with bolt 9 penetrating the limiting groove 10 on the seat plate 1 and seat plate 2 and screwed into the threaded hole 1 of the slider 4. Bolt 2 is then inserted through the through hole on the seat plate 1 and seat plate 2, and a stop block 11 is threaded onto one end of bolt 2, fixing the stop block 11 at the groove opening of the slide 3. Under external force, the soft steel 5 drives the slider 4 to slide within the slide 3, stretching or compressing the damper 7 and the rubber pad 8 on the same side according to the direction of the force, thus buffering the force.
