GQF-C-type bridge expansion joints is a novel device Highway Planning and Design Institute, the products are suitable for Heavy Traffic Area highways, urban bridges, viaducts and Interchange Project. GQF-C-type expansion joints made an entire length of rubber seal, GQF-C-type bridge expansion joints, a group of just qualitative edge beams and anchor components. The inside edge of steel beams can be fixed with a rubber seal groove. Solid welded steel beams at anchor outside, with embedded steel beam ends are welded, high-strength concrete pouring after the transition, with the beam connecting reliable, smooth engagement with the deck, sealing sealing, stretching flexible, smooth traffic, use long life characteristics. Use stretching the amount of 0 ~ 80mm bridge. Single expansion joint material: steel edge beam: the use of steel rolled 16Mn, the unit appear before the c-shaped. Rubber Seal: chloroprene rubber, has good aging resistance, flexibility can. Solid anchors: There anchor, anchor ring, three anchor plate structure, the design engineer can choose according deck design thickness, spacing is generally 20cm, the factory can also be manufactured according to specific design engineers. Road bridge expansion joints requires expansion joints in parallel, perpendicular to the axis of the bridge in both directions, can freely scalable, secure and reliable, expansion joints, the vehicle should be smooth too, no sudden jump and noise; to be able to prevent the infiltration of rainwater and garbage mud obstruction; installation, inspection, maintenance, eliminate the dirt to be simple and convenient. Set expansion joints, railings and the bridge deck to be disconnected. XF series bridges telescopic device, the structural characteristics XF oblique bearing bridge expansion devices supported bridges XF oblique device consists of stringers 1, displacement control box 2, the support beam 3, pressing the cradle 4, the pressure bearing 5, anchor plate 6, anchoring ring 7, sliders, and the like (see photo). Support beam 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, GQF- Z-type bridge expansion joints, 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 telescopic device greatly improve the ability to adapt to the slope of the bridge.
