Pot rubber bearing factory direct two-way activity _ rubber bearing basin _ pot rubber bearing activities 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 basin rubber bearings, the maximum horizontal load, must have good control of external constraints, to pay sufficient attention to this point, the compressive stress checking, design axial force is composed by the following formula. Area design axial force, quarter panels compressive strength value, material factor, curved sliding surface after reduction, the projected area of ??the curved sliding surface to calculate the coefficient. Turn the performance, designed to meet the structural requirements after a certain amount of surplus should also be considered, in general should increase the corner, pot rubber bearing test, spherical bearing holistic learning ability tests, usually including vertical bearing capacity, the level of capacity, friction coefficient and rotational performance tests. There seismic performance requirements for seat should be pulling force on the test, the test should be carried out at the factory or resale testing facility, spherical bearing vertical load test two-way activity pot rubber bearing, spherical bearing vertical load test , the general design of the test load shall be 1.5 times the vertical load test type spherical bearings should be placed in the test machine bearing plate center position, after confirmation, we should first conduct a formal pre-press and then loading activities basin rubber bearing, no load and load theatrical 2min displacement sensor data recorded until after the test load pot rubber bearing universal activity, the regulator 3min after unloading continuous loading process three times. Low height laminated rubber bearing construction (eg for steel bearing on the general height of small span bridges 90 ~ 180mm, experimental study of the mechanical properties of laminated rubber bearings highway bridges, mainly in order to develop and revise highway bridges and culverts and for the transportation industry standards to provide a reliable basis for the second test conducted several studies, such as the use of drum line contact bearings, rolling friction of steel and steel, in addition to corrosion and damage due to slippage events pot rubber bearing, so When the coefficient of friction than the design value of expected large, the influence of the level of damage and rotational movement, but also many features of the contact surface is difficult to control the precision in many cases the same damage to the line contacting the holder, and therefore, the calculation of the coefficient of friction identified the need to pay attention to this situation. By the early 1980s, laminated rubber bearings appeared nearly ten years of history and applied in China, and has been widely used in roads and bridges, but in the bridge design specifications related to laminated rubber bearings rough and the corresponding laminated rubber bearing architectural design calculations performed under the height of only 28 ~ 56mm), easy construction and installation and replacement.
