Seismic Bearing Manufacturers phone? Click here to see | grid seismic bearings | bearings provided by Hao-seismic engineering rubber. We are Hengshui HaoTong Engineering Rubber Co., Ltd. (www.htgcxj.com) located at: Hebei Hengshui specializes in: grid bearings, bridge expansion joints, water stop, bridge bearings, rubber bearings, ball bearing steel highway bridge Supports real-bridge applications. Highway bridge bearing force has been used in many practical quasi-high-speed railway bridge Guangshen Stone Bridge in a special dragon. In order to meet the navigation requirements and restrictions of the existing lines of seismic bearings, two shunt manufacturers are using some of the main span continuous prestressed concrete bridges, roads and bridges bearing this bridge in the 1990s can be considered part of the country's largest prestressed concrete continuous bridge. During the construction phase in order to detect all prestressed girder bearing closed due to changes in reaction force, to verify the use of sub-reaction force to adjust the tension generated by the reaction force, in order to convert crude bearing system to reduce the impact of design intent creep in end fulcrum arrangement was newly developed load bearing rubber bearing basin, the main highway bridge bearing arrangement in accordance with the relevant requirements. Tension overshoot on the main beam closed after a short speech in the fulcrum reaction force changes were tested, the results prove that the work bearing in good condition, and highway bridge bearing reaction force or overshoot will also shipped theoretical calculations The reaction force changes consistent process, indicating that the highway bridge bearings stable performance, played a counter-force detection of stools or role, but also reflects the use to meet the design requirements, to achieve the desired results, the measured values ??with the theoretical calculations of the plot rebate value is closer. Reaching effects. Highway bridge bearing functional requirements for reduction on the bridge, the bridge should have a rubber isolation bearings bearing conventional basic functions, such as weight highway bridge support structure and live load, absorbing upper telescopic displacement pick oh shares , rotation and deflection under normal environmental conditions and seismic grid bearing curing conditions, be able to work during normal highway bridge bearing design life, abnormal environmental conditions, the highway bridge bearings should be zero take emergency measures. Although rubber bearings designed to Che Kung Hu search shear, highway bridge bearings single nor can it be used as a long withstand continuous shear. If it is used to design to withstand tension, be especially careful. Limit values ??chosen bridge seismic bearings, highway bridge bearing structural engineer should be obtained and manufacturers of dual recognition. Design pressure force and manufacturers of dual recognition. Design compressive stress and shear deformation is determined by the following formula. Design compressive stress, seismic design pressure highway bearing, effective overlapping area between the effective plane ian and a maximum design compressive stress, the maximum design pressure highway bridge bearings, highway bridge bearings top and bottom surfaces.
