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 the 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 that: the use of heavy bridge expansion joints. Adapted to the development trend of China's transportation industry, the product selection, structure in the original first generation of products based on a major breakthrough and enhanced. Load-bearing structure and the displacement control system GQF-MZL-type bridge expansion separately, when the two forces interfering, 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 They are supported on the inside with a vertical beam of traditional practices, so that the large amount of displacement of the telescopic device is very advantageous to reduce 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, or a four-link structure prone to self-locking phenomenon, GQF-Z-type bridge expansion joints, influence extendable and easy to ensure uniform displacement ills. Problems anchor bars Modular bridge expansion joints in precast beams for (board) and the end of the back wall joints anchor bars are embedded in two different circumstances. The general design is symmetrical with respect to a given bridge width center of the beam (plate) end portion embedded steel, is embedded in every piece of steel beam position (board) are not the same inside, to the construction more difficult, GQF -F-type bridge expansion joints, thus anchoring the center of each piece should be reinforced beams (board) is symmetrical to the set, this should give full consideration in the design. During the construction of the bridge to ensure the role of anchor bars. In pouring 8 ~ 10cm thick concrete deck is done only setting is not desirable, it does not actually make joints firmly positioned angle and the beam (plate) and the back wall of concrete links into a whole, the formation of unstable hidden, retractable joints, expansion joints need to strengthen conservation efforts. GQF-F type bridge expansion joints GQF-F type bridge expansion joint rubber seal intermediate technical requirements: the use of chloroprene rubber (CR) and the temperature of the sealing joints suitable rubber band is -25 ℃ - + 60 ℃ area using natural. rubber (NR) sealing rubber band expansion joint device for temperature of -40 ℃ - + 60 ℃ Region Single expansion joint main material: steel edge beam: the use of steel rolled 16Mn. 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.
