Sliding bearing concrete corner hinge may alternately positive and negative test occurs to double, even so steel unidirectional sliding bearings, usually does not lose its security, while, if the concrete is completely cracked hinge neck, alone in Alternating corner but closed under the action of sliding bearings that can withstand the full load hinge. 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 of steel two-way sliding bearings, the original concrete information on the calculation method described below hinge, unidirectional rotation hinge bearing concrete, concrete joints and neck area is calculated and judged OK. The maximum design load bearing sliding under constant load calculations corner corner dead load 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, the calculation coefficient hinge section the length of the short side. Neck section sliding bearing hinge generally be made of concrete circular or octagonal, neck diameter is smaller than the root of the concrete hinge Nanjing map size, splitting tensile stress usually made of concrete reinforced to withstand the bolt, the bolt arrangement of tendons minimum height of about 0.7d, sliding bearing spiral bar area can be estimated, the axial force acting on the hinge, spiral reinforcement diameter, often due to the design of the bridge structure and other factors truss bridge bit bidirectional sliding bearings manufacturers, Cross the bridge may be completely unbalanced arrangement has caused some tension and compression support at the problem occurs repeatedly. That pressure is tension, based on past experience in the design, the proportion of the sliding bearing bridge across the edge of the hungry should be controlled at 0.52-0.62, when using the side span span of 0.5 or more hours. To set the general tension in the transition pier bearing, not only that bridge, sliding bearing some large venues between roof trusses supporting column will appear the same situation. In order to overcome the pull force structure using some balance weights approach bidirectional sliding bearings, but multi-use set of skills under pressure and can withstand the tension mount form to apply, therefore, support the emergence of structure known as the twelfth lunar month in the engineering business production and sales base in the form of produce. Grid unidirectional sliding bearings manufacturers, two-way sliding bearings, the contract Shou credibility of enterprises provided by Hengshui HaoTong Rubber Company.
