Single is a new type of bridge expansion joints bridge expansion Highway Planning and Design Institute, the products are suitable for high-volume traffic area highways, urban bridges, viaducts and Interchange Project. GQF-C-type expansion joints entire length by a rubber seal, a group of just qualitative edge beam 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 welded beam end, high-strength concrete pouring after the transition, with the beam connection reliable, smooth engagement with the deck, sealing sealing, stretching flexible, smooth driving, use long life. Use stretching the amount of 0 ~ 80mm bridge. Single expansion joint material: steel edge beam: 16Mn steel-rolling, the Ministry of c-section shape. Rubber Seal: chloroprene rubber, has good aging resistance, flexibility can. Single-type bridge expansion joints installed before site preparation: Single-type bridge expansion joints are manufactured and assembled in the factory, if the whole long joints need not be transported or engineering construction segment, to be welded at the scene after one, then assembled rubber seal. Single-type bridge expansion joints installed (1) joints hoisting, check which line line is coincident with the center line of the beam seam joints rg40, its top surface elevation is consistent with the road, time to adjust. (2) pre-delivery rebar and welded joints firmly anchors, and then across the 12 or 16 levels of reinforcement (3) immediate dismantling joints positioning plate, engraved to locate the screw, and rubbed the burr grinding wheel with horn, make up paint . (4) sealed with adhesive tape or the top surface of the wood joints seam in the slot 50 of the pouring of concrete parts; with plug-in vibrator, vibrator fully dense. (5) over smooth concrete surface segment. Check the top surface of the joints with a ruler, over segment c80 joints, and the road should be smooth. Only well after the opening of the concrete health. (6) with an anti-wall, sidewalk construction joints joints, the Senate made the job of the mounting process. Gallop Bridge bridge expansion joints refers to the deformation of the bridge to meet the requirements, usually between two end of the beam, or set the position articulated joints on the bridge between the end of the beam and the abutment. Require expansion joints 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 garbage soil obstruction; installation, inspection, maintenance eliminate the dirt to be simple and easy to use. Set expansion joints, railings and the bridge deck to be disconnected bridge expansion joints in accordance with the performance and installation methods can be divided into: GQF-C type, GQF-Z type, GQF-L type, GQF-F type bridge expansion joints . Which Gallop GQF-MZL number of model type bridge expansion joint device is the use of hot-rolled shaped steel bridge expansion joint device overall shape of the design. GQF-C-type bridge, GQF-Z type, GQF-L type, GQF-F-type expansion joint device for stretching the amount of 80mm below the bridge joints, GQF-MZL type expansion joint device is by the side beams, beams, Modular bridge expansion joint device beams and linked institutions, and for stretching the amount of 80mm-1200mm of large and medium span bridges.
