Panzhihua [GQF-80 bridge expansion joints] have our military bridge, do not worry, GQF-80 bridge expansion joints C-type bridge expansion joint is Highway Planning and Design Institute, a novel bridge expansion devices, products for Heavy Traffic lots of highways, urban bridges, viaducts and Interchange Project. GQF-80 bridge expansion joints and structural features and functions GQF-80 bridge expansion joints, C-type bridge expansion joint consists of a whole length of rubber seal, a group consisting of steel edge beams and anchors. The inside edge of steel beams can be fixed with a rubber seal groove canal. Solid welded steel beams at anchor outside, with embedded steel welded beam end, after pouring high-strength concrete transition section, Comrade beam reliable connection, with smooth engagement with the deck, sealing sealing, stretching flexible, smooth ride, long life characteristics. For stretching the amount of 0-80mm bridge. GQF-80 bridge expansion joints Main material: GQF-80 edge girder steel bridge expansion joints: use 16Mn steel rolling, C-shaped cross section. Rubber Seal: chloroprene rubber, has good resistance to aging, flex resistance can. GQF-80 bridge expansion joints and 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. Bridge expansion requirements telescopic device in parallel, perpendicular to the axis of the bridge in both directions, can freely scalable, secure and reliable vehicle should be smooth too, no sudden jump and noise; to be able to prevent the infiltration of rainwater and mud blocked garbage; installation, inspection, maintenance, eliminate the dirt to be simple and convenient. Set expansion joints, railings and the bridge deck to be disconnected.
