Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of rubber bearings, and specifically relates to a novel bridge rubber bearing. BACKGROUND

[0002] The bridge bearing is a key structural component for connecting the beam body and the pier in the bridge construction, and its function is to fix the upper structure on the pier, bear various forces acting on the upper structure, and reliably transmit various loads, structural resonance response, vehicle vibration response, wind vibration response, noise response, etc. to the pier; under the action of load, temperature, concrete shrinkage and creep, the bearing can adapt to the rotation angle and displacement of the upper structure, so that the upper structure can freely deform without generating additional additional internal force, and various vibration responses and noise responses are smoothly transmitted to the pier, so as to avoid aggravation of structural resonance and protect the safe operation of the bridge.

[0003] China has a long history of bridge construction, and the bridge construction develops rapidly. The corresponding bridge bearing technology has also developed rapidly, especially the rubber bearing structure is simple, low in cost, convenient to install and replace, and has excellent seismic mitigation effect, and plays an important role in the construction of large and medium-sized bridges.

[0004] The conventional rubber bearing structure adopts a middle steel plate and rubber layering alternately and uniformly. Since the middle steel plate is generally 2-8 mm steel plate according to the size of the bearing, the upper and lower surfaces of the rubber bearing body have small rigidity. There are many construction units for various projects, and the construction organization ability and beam body installation technology are uneven. During the installation of the bearing, the beam body is prone to load deviation, the bearing is prone to bias, and during the operation of the bridge, the bearing is long-term under non-uniform load working condition. Abnormal bulging and deformation of the bearing caused by long-term load deviation of the bearing aggravate the unfavorable working condition of the bearing, and the service life of the bearing is greatly shortened.

[0005] The conventional rubber bearing meets the displacement of the beam body in all directions through the horizontal shear displacement of the bearing. The upper and lower surfaces of the rubber bearing body have small rigidity, and the edge position of the bearing is prone to deformation, which causes poor contact, reduces the effective contact area, and leads to a decrease in the working condition of the rubber bearing under stress. When the displacement of the beam body reaches the limit displacement of the bearing, the edge of the bearing is significantly deformed due to the increase of friction force, the horizontal anti-sliding ability of the bearing is weakened, the rubber bearing deviates, and in severe cases, the beam body is pressed and even deviated.

[0006] In recent years, a large number of old bridge reconstruction and support replacement construction have appeared. The replaced support has not reached the normal service life. The common diseases of the bridge rubber support in service for more than 8 years are beam body eccentric compression, support running, beam body void, abnormal deformation and the like, which causes great safety hidden danger to the bridge operation. Therefore, the development of a new type of rubber support structure, the improvement of the self-adaptability of the support, the improvement of the stress working condition of the rubber support, the improvement of the anti-sliding performance of the rubber support, the reduction of the installation and construction requirements of the rubber support, the improvement of the service life of the support, the reduction of resource waste, the reduction of the safety hidden danger of the bridge operation and the reduction of the maintenance and management cost are the goals of the continuous progress of the bridge support technology.
