Finished sliding bearings of various types of production enterprises, universal sliding bearings, sliding bearings Changde 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, spherical steel bearing sliding support Block offset flat base plate area, Block resistance moment plate flat area, the design value of support cushion stone bearing stresses. Base plate stress checking. For slide bearings themselves, should be checking their bending stress, concentration and distribution of press companionship pressure manufacturers to bear the following bear. Then checking its curved place according to the following formula. Sliding bearings or cylindrical roller bearings in the arc line contact with the plate for universal sliding bearings, its reaction force should satisfy the formula requirements. On that roller bearing, the radius of the curved surface of the contact points twice directly. Assumed by the beam end bearing plate fulcrum reaction force to the uniform distribution of the bearing pads bridge pier sliding bearings, sliding support in ensuring the cushion-like pressure should not exceed the concrete partial pressure of shadow beefy design premise value is large enough. Sliding bearing to be considered due to temperature changes and other factors, the pad has a maximum allowable level of displacement will cause additional moment sliding bearings, sliding bearings considering the calculated values ??behind. Britain had to put the hinge bearing column tests conducted research model. Its structure shown in detail, the basic conclusion is that the test load is applied 300kn, overloaded or destroyed bridge over the safety factor of displacement under very high; load up 1500kn, the sliding bearing rotation angle of up to 11.5 plate sliding bearings, concrete stresses exceed the ultimate strength of the concrete several times, but did not damage any danger signal, and because increasing the bending stiffness of reinforced sliding bearing. Past the neck reinforcement can be reduced. Sliding bearing has recommended the neck reinforcement designed to withstand long processing time required to install and according to the test results. Hinge in reinforced concrete detail design is good or bad has a crucial impact on the use of the effect of concrete hinges, so that countries are conducting research. Sliding support for the construction and reinforcement hinges made a lot of design and made a very good suggestion. Through the thick steel plate instead of concrete, etc., at different rotation angles of the shear and compressive strength in the ultimate strength of the loading test. Two models hinge reinforcement layout.
