XF XF bridge expansion joints bridge expansion joints by stringers, displacement control box 2, the support beam, pressed bearings, bearing supports, anchor plate, anchor ring, sliders, etc. composition. Support beam joints using oblique arrangement, each of the displacement control box located only a support beam, pressed bearings and bearing seat using rubber bearing basin structure, the rubber placed in pot steel ring, Rubber is not in contact with air, unfair greatly improve the aging resistance of the rubber, and the rubber in the three-dimensional stress state, the volume can not be changed several subjects, so the bearing preload will not disappear. In addition, the displacement of the control box is designed to be spherical bearing shaft, when the telescopic device is used in slope bridge, you can rely spherical swing change to adapt to the height of the telescopic opposite sides, so that the joints greatly improve the ability to adapt to the slope of the bridge. XF large amount of displacement of bridge expansion joints with reasonable design, beautiful appearance, high strength, good displacement volume, synchronization performance, small stretch resistance, smooth traffic, good waterproof performance, long life and other characteristics, is an ideal bridge expansion . In bridge design, should be set aside slots. Reserve tank should also set aside reinforced φ20 @ 250, pre-reinforced concrete beam with anchor shall comply with the relevant provisions. The company operating the bridge bearings, bridge expansion joints, 80 joints, 160 road and bridge expansion joints and other articles of bridge bearings factory Wei Xin Hengshui Rubber Co., Ltd.
