GQF-E-type bridge expansion joints Features: low building height, simple structure, easy installation, with significant reliability, comfort and durability. Suitable for deck pavement thickness equal to or greater than 80mm, stretching the amount of 80mm or less all kinds of bridges, which is convenient to replace the old bridge expansion joints, and for the construction of a new bridge to use. Not because of some expansion joints installed jumping phenomenon will have, not only on the country's roads and bridges in existence, in foreign countries has not been resolved, bridge expansion joints, we have to eliminate the step to prevent jumping, maintain good general road bridge expansion joints , departments and construction units adopted many effective measures and approaches, moving escape considerably reduced bridge expansion joints Bump. Installation of bridge expansion joints which is the construction of a highway bridge construction project is extremely important, installation quality directly affects the smooth ride and comfort, quality of service and useful life of large bridges. GQF-E-type bridge expansion joints 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. The use of natural rubber (NR) sealing rubber band expansion joint device for temperature of -40 ℃ -60 ℃ area. Road bridge expansion joints is a bridge structure activities provided at the upper end, the deck off the telescopic device at the joints. Telescopic device installation role is intended to ensure that the temperature changes in the upper structure, concrete creep and shrinkage, as well as bridge expansion joints under heavy loads, where the displacement can be achieved without generating extra additional internal forces, and to ensure driving comfort. Domestic bridge expansion joints are usually provided at the movable end of the upper structure and abutments, and convergence at the Joint superstructure. Single type modulus joints: GQF-C type, GQF-Z type, GQF-L type, GQF-F type, GQF-E type collectively. All is the use of hot-rolled steel shaped the overall shape of the design of the bridge expansion joint products for stretching the amount of 80mm below the bridge joints. Code representation bridge expansion joints and People's Republic of China Communications Industry Standard representation consistent. In GQF-C60, GQF-F80, GQF-C60 (NR), GQF-F80 (CR) type bridge expansion joints, for example, which is GQF Transportation industry standards for bridge expansion joint device code, type code: Direct link chain beam type: (C, Z, F, E, L) represents the shape of shaped steel, telescopic device numbers indicate the amount of displacement: 0-80mm. NR and CR represent types of rubber: NR indicates natural rubber, CR represents neoprene rubber bridge expansion joints used in the scope of application: 1, chloroprene rubber (CR) of the expansion joint device for temperature of -25- + 60 area 2 , the use of natural rubber (NR) in the expansion joint device for temperature of -40- + 60 regional GQF-MZL160 type expansion joints with Chinese characteristics of the new highway bridge expansion. The use of side beams, beams of a bridge stretching devices, beam, displacement control system, seals and other components of the composition of the rubber band. Bridge expansion joints bird-shaped rubber seal according to bridge wide, the whole production of chloroprene or EPDM Modular bridge expansion joints, has a good anti-aging, flex resistance can. Adaptation bridge beam end level, horizontal, vertical deformation, stretching resistance is minimal. Steel edge beam bridge expansion joints using 16Mn finishing made Φ16 anchor plate and anchor tendons with good mechanical properties. The role of impact force on the vehicle side of the beam passing through the anchor member to the balance beam, has a long service life. Bridge expansion joints production (Figure) | Modular bridge expansion joints | bridge expansion joints provided by the Road and Bridge Engineering Co., Ltd. Hengshui Gallop. Hengshui Gallop Road and Bridge Engineering Co., Ltd. (www.hsjllq.com) (www.china-2000.com) located in Hengshui City, Hebei Province Lake District.
