Sliding bearing concrete corner hinges may occur alternately positive and negative to double measure, even so, do not usually lose their security directional damping sliding bearings, sliding bearings while universal rotation damping, if concrete hinges neck Ministry completely cracked, alternating single action under the corner but when closed, the hinge sliding bearings can withstand all loads. According to reference, concrete hinge design method can be divided into one-way and two-way rotation of the rotary joint bearing hinge support analysis and calculation, the original concrete information on the calculation method described below hinge, unidirectional rotating hinge bearing concrete, concrete hinged neck area is calculated and judged OK. The maximum design load sliding bearing dead load does not exceed the maximum compressive strength of concrete standard value calculation 1.5n corner maximum design load and dead load ratio of sliding bearings under constant load damping effect corner sliding bearings, corner often happens, calculation coefficient, hinge section short side length. Quality non-shrink grout should be required to explain the design drawings for the standard, but should not be lower than the standard strength concrete substructure, non-shrink grout quality requirements should be determined by examining the slide bearing grout most overall quality should be comply with the relevant provisions of the standards, the Japanese generally use non-shrink water slurry quality specification requirements. Cement is a cementitious material, fine aggregate and sliding bearing water formulated as discretionary, sliding bearing mortar in highway bridge construction mostly commonly used in mortar, and in the bridge repair project, in addition to bearing material outside the single infusion the damping sliding bearings, a relatively large range of repair parts can be used cement concrete materials are often used to cement mortar, cement mortar composed of cement mortar composition of materials in addition to the base material does not contain coarse, the sliding bearing essentially concrete constituent materials require the same single also vary. The use of additives or issues should be noted. Incorporated in the mortar or concrete admixture mixing process, the purpose is to change its performance characteristics, the main function is divided into admixture.
