Our factory production process of Pot bearing:
Machining workshop and machine works: 2.Finished machining half-finished products and Spraying process
3. Applying silicone grease :
4.and embedded bolts
5. Assembing of pot bearings and store
Bridge bearings and expansion joint are important parts of whole bridge components, but the amount money that spent on bridge bearing and expansion joint is only 2-3.5%, it is absolutely a wise choice to evaluate it within the whole project to prevent failed choice bringing unnecessary costs.
Pot rubber bearing is used to semi closed steel in pelvic cavity of the elastic rubber block, in three to the stress state has the characteristics of fluid to achieve the rotation of the upper part of the bridge, also rely on steel plate in the center of the F4 board and the upper seat plate of stainless steel plate between the low friction coefficient to realize the horizontal displacement of the upper structure, bearing to withstand the shear no longer by the rubber completely bear, and indirect effects on the steel bottom slip between the pot and F4 board and so on.This series bearing capacity is 31 levels, bearing capacity 0.8MN-60MN, can meet the needs of large-scale construction of the bridge.
2.Advantages of pot rubber bearing
Large horizontal displacement, flexible rotation, light weight, compact structure, simple structure, low construction height, convenient processing and manufacture, saving steel, reducing the cost and other advantages, is suitable for the use of a large bridge bridge is an ideal bearing.
3.Performance and classification
a.Two-way active support: with a vertical rotation and vertical and horizontal slip performance, code named SX.
b. One way movable support: with a vertical rotation and a single direction of slip performance, code named DX.
c. Fixed bearing: only with vertical rotation performance, code named GD.
