Highway bridge bearings Hao-recommended supply shock highway bridge supports national certification provided by Hao-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 requirements of navigable highway bridge bearings, and limited existing lines, the two shunt manufacturers are using some of the main span continuous prestressed concrete bridge two-way highway bridge bearing slide, highway bridge bearing this bridge in the 20th century 90 age 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 bearings are generally provided on the bridge when using a fixed end and the movable end, the use of seat height, the horizontal displacement of the upper structure of the two ends of the beam with a common bearing shear deformation is complete, each bear the general seismic highway bridge supports, can also be used as a small thickness of rubber bearings fixed bearing, roads and bridges bearing installation temperature should be controlled within the region or time period the annual average temperature of the season will be installed for the best. If you must be installed at the maximum or minimum temperature, in order to avoid the occurrence of excessive highway bridge bearing shear deformation. The year when temperatures are Zaiding product from the main beam, the self-adjustment to the center position. This method is used in the railway bridge can be, and in the roads and bridges, because the number of multi-axle damping wide highway bridge bearings, bearing the number of roads and bridges too, are generally difficult to achieve, according to the temperature at installation calculated and determined to produce a pre-displacement method highway bridge support for installation, generally difficult to achieve. If you can not be expected to be installed at the time of the annual average temperature, may also be appropriate to increase the design of highway bridge bearings bearing selection easy way to deal with the height, which is extremely low when asked to install, make sure to consider the maximum amount of displacement of the upper structure due to high bottom shear deformation temperature impact pre-need to increase the amount of displacement counted, consider choosing to increase the total thickness of the rubber layer of rubber bearings required.
