Description

Technical Field

[0001] This utility model relates to vibration reduction and isolation devices in the fields of engineering technology such as bridges and buildings, and in particular to a wind-resistant friction pendulum bearing for buildings. Background Technology

[0002] Traditional designs for friction pendulum bearings primarily focus on their damping and isolation performance, crucial for buildings in earthquake-prone areas to enhance their safety and durability during seismic events. However, these designs often fail to adequately consider the wind resistance requirements of friction pendulum bearings, especially in areas with high wind speeds or high-rise buildings, where the impact of wind on structural stability and safety cannot be ignored. Without appropriate wind-resistant measures, extreme wind conditions can lead to instability or even damage to the bearing structure, increasing overall building safety risks. When strong winds act on a building, without proper wind-resistant measures, friction pendulum bearings may experience displacements exceeding their design specifications, resulting in instability or damage to the bearing or building structure. This instability not only increases the risk of building collapse but can also damage internal structures and facilities, increasing economic losses and endangering human safety. Therefore, it is necessary to develop a wind-resistant friction pendulum bearing for buildings that possesses sufficient strength to withstand strong winds without interfering with the damping function of seismic isolation bearings under seismic loads.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A wind-resistant friction pendulum bearing for buildings includes a friction pendulum bearing body and a wind-resistant device. The wind-resistant device is disposed around the friction pendulum bearing body and has a pre-set fracture zone.

[0006] Preferably, the wind-resistant device is arranged in a circular shape around the friction pendulum support body;

[0007] Preferably, the wind-resistant device is arranged in a rectangular shape around the friction pendulum support body;

[0009] Preferably, the wind-resistant device includes several rubber plates (4), and the rubber plates (4) have a pre-set fracture zone.

[0010] Preferably, the wind-resistant device includes several metal plates and rubber plates, which are arranged at intervals and fixedly connected by several clamps;

[0011] Preferably, one of the clamps includes two clamp bodies;

[0012] Preferably, one of the clamps includes four clamp bodies;

[0013] Preferably, the hoop body is provided with a groove;

[0015] Preferably, the metal plate is made of stainless steel plate, weathering steel plate, or ordinary steel plate after anti-corrosion treatment;

[0016] Preferably, the rubber sheet has a Shore hardness of 85A or higher and a thickness of 5mm.

[0017] Preferably, the metal plate is provided with a plurality of bolt holes, and the metal plate is fixed to the upper support plate and the lower support plate of the friction pendulum support body by bolts.

[0018] Preferably, the rubber plate is provided with several bolt holes, and the rubber plate is fixed to the upper support plate and the lower support plate of the friction pendulum support body by bolts.

[0019] Preferably, the clamp includes a clamp body and a fastening mechanism;

[0020] Preferably, the fastening mechanism is a bolt and nut, with bolt holes three for fixing and adjusting the clamp;

[0021] Preferably, the shear strength of the bolts in the fastening mechanism is lower than a preset shear strength.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] First, by installing wind-resistant devices around the friction pendulum support, the resistance of the friction pendulum support to wind and the stability of the overall structure are greatly improved. The diverse layout schemes (including circular and rectangular arrangements) expand the applicability of the support, allowing it to be customized according to different building design requirements, thereby maximizing wind resistance performance.

[0024] Secondly, the wind-resistant device can be set with different strength levels, which not only provides sufficient wind-resistant rigidity to maintain stability under wind force, but also, in the event of an earthquake, the break point design allows the wind-resistant device to break at a predetermined position, which has enough strength to resist strong winds, but does not interfere with the damping function of the seismic isolation bearing under seismic action.

[0025] Finally, the wind-resistant device is easy to install and maintain. The metal and rubber plates are bolted to the support, and the metal and rubber plates are fixed with clamps, which simplifies the installation process and facilitates future maintenance. The use of a fastening mechanism increases the flexibility of adjusting the clamp tightness, allowing adjustments to be made according to actual conditions to ensure that the wind-resistant device can maintain optimal performance in different environments.

[0032] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0033] Example 1, please refer to Figures 1-2 The present invention provides the following technical solution:

[0034] A wind-resistant friction pendulum bearing for buildings includes a friction pendulum bearing body and a wind-resistant device. The wind-resistant device is disposed around the friction pendulum bearing body and has a pre-set fracture zone.

[0035] The wind-resistant device includes four metal plates 3 arranged in a rectangle around the friction pendulum support body. The metal plates 3 have a pre-set fracture zone 3-1 and several bolt holes 3-2. The metal plates 3 are fixedly connected to the upper support plate 1 and the lower support plate 2 of the friction pendulum support body by bolts 3-2. The metal plates 3 are made of stainless steel plate, weathering steel plate, and ordinary steel plate after anti-corrosion treatment. When an earthquake occurs, the wind-resistant device breaks at the pre-set fracture zone 3-1, which can ensure that the wind-resistant device will fall off in the manner expected by the design, thereby ensuring that the support can continue to work normally.

[0036] As another embodiment of this utility model, please refer to Figure 3 Metal plate 3 can be replaced by rubber plate 4. The Shore hardness of rubber plate 4 is 85A and the thickness of rubber plate is 5mm. When an earthquake occurs, the wind-resistant device breaks at the pre-set fracture zone 4-1 of the rubber plate, which can ensure that the wind-resistant device will fall off in the manner expected by the design, thereby ensuring that the support can continue to work normally.

[0037] As another embodiment of this utility model, please refer to Figure 4 The wind-resistant device is arranged in a circle around the friction pendulum support body; it includes 3 metal plates 3 and 3 rubber plates 4, which are arranged at intervals and fixedly connected by several clamps 5.

[0038] The metal plate 3 is fixed to the upper support plate 1 and the lower support plate 2 of the support through bolt holes 3-2;

[0039] The rubber plate 4 is fixed to the upper support plate 1 and the lower support plate 2 of the support through bolt holes 4-2;

[0040] The clamp 5 includes a clamp body 5-1, bolt holes 5-2, and a fastening mechanism;

[0041] The fastening mechanism consists of bolts and nuts, with clamps fixed and adjusted via bolt holes 35-2;

[0042] The shear strength of the bolt is lower than the preset shear strength. When an earthquake occurs, the wind-resistant device breaks off from the bolt, which ensures that the wind-resistant device will fall off in the manner expected by the design, thereby ensuring that the support can continue to work normally.

[0043] As another embodiment of this utility model, please refer to Figure 5 The hoop 5-1 is provided with a groove 5-3, which serves as a pre-set fracture zone. When an earthquake occurs, the wind-resistant device will break off from the groove 5-3. This ensures that the wind-resistant device will fall off in the manner expected by the design, thereby ensuring that the support can continue to work normally.

[0044] In another embodiment of this utility model, the two hoops 5-1 can also be combined to form a pair for fixing the metal plate 3 and the rubber plate 4;

[0045] In another embodiment of this utility model, the metal plate 3 and the rubber plate 4 can be fixedly connected by vulcanization bonding.

[0046] In another embodiment of this utility model, the metal plate 3 and the clamp 5 can be made of stainless steel plates produced by Wuxi Taifu Stainless Steel Co., Ltd.

[0047] By designing wind-resistant devices, the supports can better resist the effects of external forces such as wind, thus improving the wind resistance performance of buildings. Specifically, as an external protective structure for the supports, the wind-resistant device has a certain degree of rigidity and strength. When subjected to lateral wind forces, the wind-resistant device can bear part of the external force, thereby reducing the stress on the main support structure and achieving a stable support effect. The strength of the pre-set fault zone in the wind-resistant device can be graded according to the pre-set seismic level, ensuring that the wind-resistant device will detach in the manner expected by the design, thereby ensuring that the supports can continue to work normally, enhancing the reliability of the system, and reducing the impact of unpredictable factors on the performance of the support system.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
