Single type modulus joints: GQF-C type, GQF-Z type, GQF-L type, GQF-F type, GQF-E type collectively. Use of shaped steel hot rolled all the overall shape of the design of the bridge expansion joint products for stretching the amount of 80mm below the bridge joints. Bridge expansion joints and the People's Republic of China traffic code representation representation consistent with industry standards. 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: straight beam chain link 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, said rubber types: NR, said natural rubber, CR represents neoprene rubber bridge expansion joints used in scope: 1, chloroprene rubber (CR) of the expansion joint device for temperature is -25- + 60 region 2 , the use of natural rubber (NR) in the expansion joint device for temperature is -40- + 60 region GQF-MZL160 type expansion joints with Chinese characteristics is a new highway bridge expansion. The use of edge beam, the beam of a bridge stretching devices, beam, displacement control systems, seals and other components of the composition of the rubber band. Bridge expansion joints bird-shaped rubber seal according to the bridge width, the whole use of neoprene or EPDM rubber production d60 joints, with good anti-aging, anti-flex performance. To adapt to the level of the bridge beam end, horizontal, vertical deformation d80 joints, stretching resistance is minimal. Bridge expansion joints using 16Mn steel edge beam finishing made anchor plate and anchor tendons Φ16 has good mechanical properties. Effect on the side beams of the impact force of the vehicle, passing through the anchor member to the balance beam, has a long service life. Gallop bridge expansion joints bridge deck expansion joint device refers to meet the requirements of the deformation, usually between two end of the beam, or set the position articulated telescopic device on a bridge between the end of the beam and the abutment. Construction 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 garbage soil obstruction; installation, inspection, maintenance, eliminating the dirt to be simple and easy to use. Set expansion joints, railings and the bridge deck to be disconnected. Type telescopic device: 1) galvanized sheet steel telescopic device. Fabricated in the small span girders bridge, when beam deformation within 20-40mm often choose. 2) steel extension telescopic device: its structure is more complex, and only in larger temperature difference between regions or larger span bridge was adopted. Steel telescopic device is also appropriate for use on the bridge of. 3) rubber expansion device. It is a rubber band as a cross stitch materials. This telescopic device structure is simple rg40 joints, good and easy to use, the effect is. In the large deformation of large-span bridge expansion joints, you can use a combination of rubber and steel telescopic device. Bridge expansion joint device construction requirements: bridge expansion 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 mud obstruction; installation, inspection, maintenance, eliminating the dirt to be simple and easy to use. c40 expansion joints, bridge expansion joints (certified), expansion joints are provided by Hengshui Gallop Road and Bridge Engineering Limited.
