The section on the concrete hinge design also part of the neck, sliding bearings to prevent the peeling section of Shanghai-Nanjing diagram under high stress, resulting split Rally Natatorium will be in the direction of sliding hinge mount, and edge splitting tensile part, this part of the rally also reinforced to withstand corrosion by configuration can slip hinge bearing, the stress state of the concrete hinges. As can be seen from the figure, the hinge necking ratio, the slide bearing allowable stress allowable pressure or slip cast may hinge bearing, the greater the sliding bearing hinge hour when the corner by the hinge portion of the concrete deformation can be rotated. And when the angle is large, the hinge portion of the concrete will crack necked, sharp increase in the pressure of concrete at this time. Sliding bearings under sustained load cracks may be due to creep deformation of concrete partially closed, sliding bearings makes eccentricity and rotational reaction force is reduced, and therefore, in determining the permissible angular and rotational torque should be based on the dead load and live load circumstances be treated differently. Laminated rubber bearings sliding bearings than drinking large pot bearing stiffness, bearing a small deformation, can Bonham large car and train high-speed stability. Compared with the rocking shaft sliding bearings and roller bearings and other bearings hinge bearings, medical and height greatly reduced, light weight, easy installation, the cost is relatively low. Seismic sliding bearing temperature range is large, due to the non-rubber bearing structure without affecting the rubber aging properties of bearing rotation exist, so durability is good. Sliding bearings suitable for a wide bridge, curved bridge, sloping bridge, cable-stayed bridges and other large-scale and long-span bridges span space of structural engineering, especially in the high-intensity earthquake bridge engineering occasion to apply more appropriate. Sliding bearings are a class structure with tensile properties can slip hinge bearings, bearings can be used as the use of tension and compression, seismic spherical steel bearing has series of product specifications for different customer choice. Damping steel ball bearings. Both can slip hinge bearing, can slip hinge bearings, Hao-Hao Rubber pass by Hengshui Rubber Company. Hengshui HaoTong Engineering Rubber Co., Ltd.
