Description

Technical Field

[0001] This utility model belongs to the field of bridge construction engineering, and specifically relates to a pot bearing with lateral wind resistance function. Background Technology

[0002] With the rapid development of bridge construction, the application of long-span bridges is increasing. For semi-floating bridge systems such as long-span cable-stayed bridges and suspension bridges, lateral wind resistance is one of the main factors affecting bridge safety.

[0003] After a conventional pot bearing is erected, it is installed between the bridge tower and the beam. Due to the effect of gravity, the intermediate steel liner is in an unstable state. Under the action of wind load, a large gap will be generated between the tower and the beam. The intermediate steel liner may fall out of the pot. In addition, the wear-resistant plate may also fall off during the collision. All these situations can damage the bearing, cause safety accidents, and thus affect the normal operation of the bridge. Utility Model Content

[0017] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0018] Please see Figures 1 to 3 The present invention includes: a basin support with lateral wind resistance function, comprising a top plate 1 and a bottom basin 2, wherein the top plate 1 is installed on the bottom basin 2 and the top plate 1 is fixed to the lateral inner side of the bridge tower for transmitting lateral wind load.

[0019] The base plate 2 is fixedly connected to the beam body and is used to confine the intermediate steel liner plate 6, the rubber bearing plate 7 and the brass sealing ring 8 therein to transmit lateral wind loads.

[0020] An intermediate steel liner 6 is provided between the top plate 1 and the bottom basin 2. While transmitting lateral loads, it can adapt to disturbances in the bridge structure due to loads and other reasons by following the rotation of the rubber bearing plate 7 below, and can also rotate in a plane within the bottom basin 2.

[0021] A transverse wind-resistant structure is also provided between the top plate 1 and the bottom basin 2, which can withstand and transmit transverse horizontal forces, limit the transverse sway of the bridge caused by wind loads, and meet the safety and stability requirements of the support body and the bridge structure.

[0022] The lateral wind-resistant structure includes a pressure-bearing structure for weakening lateral wind loads and a rebound structure for providing restoring force to the intermediate steel liner 6. The pressure-bearing structure is located in the basin 3 at the top of the base basin 2, and the rebound structure is located between the limiting pressure plate 12 on the outside of the intermediate steel liner 6 and the base basin 2. The limiting pressure plate 12 uses the high-strength bolts 11 and the compression spring 13 to limit the intermediate steel liner 6 within the basin 3 of the base basin 2, ensuring that it can move within a certain lateral range without falling out of the basin 3 of the base basin 2.

[0023] The pressure-bearing structure includes a circular rubber pressure plate 7. The bottom of the rubber pressure plate 7 is in contact with the basin 3, and the top of the rubber pressure plate 7 is in contact with the bottom of the intermediate steel lining plate 6 inside the basin 3. It is used to transmit vertical loads and can also realize the vertical rotation function of the support through its own deformability.

[0024] The rubber bearing plate 7 is provided with a compressible structure, which consists of several annular protrusions 9 arranged in a ring around the center of the rubber bearing plate 7. The compressible structure can be compressed and can also self-restore.

[0025] The compressible structure allows the rubber bearing plate 7 to withstand lateral loads and be compressed under large forces, thereby reducing the impact of wind loads on the beam. In addition, the compressed compressible structure can self-reset, thereby pushing the intermediate steel liner 6 to keep the flat wear-resistant plate 5 in close contact with the stainless steel plate 4, reducing the impact of wind loads.

[0026] The rubber bearing plate 7 has the compressible structure on one or both sides, which greatly improves its compressibility. It can weaken the lateral wind load through its compression deformation ability, and can also use its own deformation recovery ability to squeeze the intermediate steel liner 6, so that the sliding surface of the support is always in contact.

[0027] The rubber bearing plate 7 has an installation step on the outer side of its upper surface. The installation step, the bottom basin 2, and the intermediate steel liner 6 form an installation groove. A brass sealing ring 8 is installed in the installation groove. The brass sealing ring 8 is used to constrain the rubber bearing plate 7 and prevent the rubber bearing plate 7 from being squeezed out during the rotation of the intermediate steel liner 6.

[0028] The rebound structure consists of several compression springs 13, which are sleeved on high-strength bolts 11. The high-strength bolts 11 pass through the limiting pressure plate 12 and the compression springs 13 and are screwed into the basin ring of the bottom basin 2. The high-strength bolts 11 are used to fix the intermediate steel liner plate 6.

[0029] The compression spring 13 is used to limit the intermediate steel liner 6 and provide restoring force.

[0030] A flat wear-resistant plate 5 is fixedly installed in the groove at the top of the intermediate steel liner 6 by countersunk copper screws 10. The flat wear-resistant plate 5 is made of polymer material and coated with grease, which can provide a low coefficient of friction.

[0031] The countersunk copper screw 10 is used to fix the flat wear-resistant plate 5 into the groove on the surface of the intermediate steel liner 6. The head is embedded in the countersunk hole on the surface of the flat wear-resistant plate 5, which has no effect on slippage and ensures that the flat wear-resistant plate 5 and the intermediate steel liner 6 are reliably connected, thus solving the problem that the flat wear-resistant plate 5 may fall off during use.

[0032] A stainless steel plate 4 is provided between the flat wear-resistant plate 5 and the top plate 1. The stainless steel plate 4 is mirror-finished and has a low coefficient of friction. It is in close contact with the flat wear-resistant plate 5 to form a friction pair, which can adapt to the displacement changes of the beam due to temperature and braking force.

[0033] Under the combined action of the deformation recovery of the rubber bearing plate 7 and the compression spring 13, the gap between the bridge tower and the beam under the action of lateral wind load is eliminated, ensuring the safe operation of the support and the bridge.

[0034] During installation, the compression spring 13 maintains a certain pre-compression amount, which can meet the wind load in both lateral directions.

[0035] Compared with the prior art, the present invention provides a pot bearing with lateral wind resistance function. The pot bearing is equipped with a lateral wind resistance structure, which can withstand and transmit lateral horizontal force, limit the lateral sway of the bridge caused by wind load, and meet the safety and stability requirements of the bearing body and the bridge structure.
