Seismic steel ball bearing arrangement of the main structure of the bridge and related forms, bearing the rational arrangement will directly affect the situation by force bearing, usually seismic steel ball bearing arrangement should consider the following basic principles: Supports must reliable delivery of vertical and horizontal beam counterforce; bearings should be due to the deformation of the longitudinal Liu 昂提 generated, lateral displacement and vertical and horizontal angle (or plane rotation) as unconstrained; carriage must be reliable transmission of vertical and horizontal reaction force; railway bridges usually have to set a fixed support bi-elastic damping ball bearing manufacturer specializing in not linking the beam, when the bridge is located on the slopes, fixed bearing should generally be set allocated direction bridge table, when the bridge is located on the flat ramp, fixed bearing general should set up at the front of the main directions of traffic. Fixed bearing should be set with a large bearing reaction force in place, long-linking reaction force larger larger continuous beam fixed bearing should be set in the middle part of the pier, so here bearing Spring, and the two Freedom stretching the length of the side of a more balanced. Several stand on the same pier should have similar vertical and rotational stiffness. Prestressed concrete beam bearing beam transverse prestressing should not generate constraints. Xieqiao and horizontal prone corner of the bridge is not easy to adopt rocker shaft and roller bearings and other lines. On uneven ground subsidence-prone areas of the bridge supports, seat height adjustment possibilities should be considered. In short layout principles seismic steel ball bearing is necessary to facilitate the transfer bearing reaction force, but also to make the bearings able to fully adapt to free-form deformation of the beam. Seismic steel ball bearing steel ball bearing seismic performance is set viscous dampers on both sides of the ordinary activities of laminated rubber bearing, while bearing normal use, the bridge beam deflection temperature, due to the slow speed of temperature change bits , viscous dampers almost no resistance to displacement, and in the earthquake, viscous dampers in the role of rapid earthquake forces, hardly displaced, will have a significant displacement of resistance, then the bridge bearing activities become a fixed bearing, so that all full-bridge piers to withstand seismic forces together to achieve the purpose of shock absorption. Viscous damper damping medium, usually using ultra-high viscosity silicone oil, to prevent leakage. Seismic steel ball bearings in general by the cylinder, piston and damping materials, the piston in the cylinder reciprocating do have the right amount of holes on the piston, cylinder built with viscous material. Structure under the action of earthquake seismic force and viscous dampers work together with the structure of import rod force, pushing the piston movement of the piston on both sides of the damping material produces a pressure difference KLQZ tension and compression-way ball bearing products, damping medium through orifice, resulting in a two-way damping force grid ball bearing price, reaching the purpose of energy dissipation. The internal structure of the damper varies, the speed index is generally between 0.1 to 1.0. Also damping force also with the piston area, the orifice size and length, cheer frequency, temperature, and other factors related to the damping material category. Viscous dampers and PTFE sliding bearing combination is also a common relief isolators.
