GQF-MZL_ZX Modular bridge expansion joints GQF-MZL_ZX Modular bridge expansion joint device is suitable for heavy-duty vehicles of more roads and bridges, including structural design GQF-MZL_ZX Modular bridge expansion joints fully complies with the heavy-duty features, greatly improving the carrying capacity and the use of stability, and effectively extend the service life. Experts believe: Heavy use of bridge expansion joints. Adapted to the development trend of China's transportation industry, the product selection, based on the original structure of the first generation of products based on a major breakthrough and improve. Load-bearing structures and displacement control system GQF-MZL-type bridge expansion separately, when the two forces interfering 13,831,886,062 clear division of labor, so that not only guarantee the security forces, while maintaining a uniform displacement, so that all beams in a displacement control box are supported on a vertical beam with traditional practices, so that the large displacement of the telescopic device is very beneficial, reducing the number of beams, so that the displacement of the control box volume is reduced to a minimum, saving the steel. The structure also overcomes the oblique supporting telescopic devices require very high precision machining and assembly of the harsh conditions, otherwise the four-link structure prone to self-locking phenomenon, affecting free and easy expansion displacement guarantee uniform ills. Modular steel anchor problem for bridge expansion joints in precast beam (plate) and the end of the back wall joints anchor bars are embedded in two different circumstances. Given the general design of the bridge are symmetrical wide center of the beam (plate) end portion embedded steel bridge expansion joints, the embedded position in each piece steel beams (board) are not the same within gqf bridge expansion joints, to increase the difficulty of construction, so the anchor in the center of each piece should be reinforced beams (board) of symmetrical set, this should give full consideration in the design. During the construction of the bridge to be reinforced to ensure the anchor role. In pouring 8 ~ 10cm thick concrete deck is done only setting is desirable, it does not actually make joints firmly positioned angle and beam (plate) and the back wall of concrete linked into a whole, the formation of unstable risks, need strengthen the joints of conservation. 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 a reliable connection beam bridge expansion joint device has a smooth bridge bonding, sealing sealing, scalable and flexible, smooth driving, long life characteristics. 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 beam centerline seam, 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, and the road should be smooth. Only well after the opening of the concrete health. (6) with an anti-wall, sidewalk construction joints, the Senate made the job of the mounting process. d40 bridge expansion joints, Gallop Manufacturing (certified), bridge expansion joints supplied by Gallop Road and Bridge Engineering Co., Ltd.
