After the test, the following conclusions by these two types of hinge to withstand pulses and pulse load combined with the design of the corner box ah, by rotation of the test made after shear test, which is similar to the case of the sliding bearings of the hinge in the concrete see manholes along the crack surface flaking, and in the steel hinges do not see this phenomenon proves steel played a role. Hinge sliding bearing is free to rotate in any direction. Sliding bearings and "existing hinge different" because of the neck is not easy even concrete, so its function is less than the steel plate to the good, which shows the pulse loads, steel hinge hinge for stable than concrete, concrete in different directions so the hinge to pay attention to vibration pound dense. According to the test of experience in Germany, hinge reinforcement shall be arranged in accordance with the test and the test results photoelastic model full-scale concrete hinges, hinge on the concrete proposal is designed primarily to account for 40% of steel arranged in a two-way slide through the midpoint of the hinge reinforcement Finished steel bearing ball joints, sliding bearing remaining 60% is disposed along the longitudinal reinforcement. Since the hinge angle resistance, anti-torque generated by the angle of rotation torque hinge at the center of the west, as the vertical force on the hinge. Under the action of the force N in the hinge will produce a concrete crack tension. Sliding bearing concrete corner hinge may occur alternately positive and negative double-entry sliding ball joint steel bearing manufacturers to double test, even so, usually does not lose its security, while, if the neck is completely cracked concrete hinges more than steel ball bearing sliding hinge, under the action of a single alternating corner but when closed, the hinge sliding bearings can withstand all loads. According to reference, the calculation method of concrete can be divided into unidirectional rotation of the hinge pin hinge and bi-directional rotation pin hinge analysis and calculation, the original concrete information on the calculation method described below hinge, unidirectional rotating hinge bearing concrete, concrete Hinge neck area is calculated and judged OK. The maximum design load sliding bearings under constant load angle corner dead load calculation does not exceed the maximum compressive strength of concrete standard value 1.5n maximum design load and dead load ratio of sliding bearing, corner often happens, calculation of the coefficient, hinge-section the length of the short side.
