[Bridge expansion joint device] in May 2015 the latest offer, I produced several models of bridge expansion joints models:. GQF-C type, GQF-Z type, GQF-L type, GQF-F type, GQF-MZL type, all hot-rolled steel design shaped the overall shape of the bridge expansion joint products. Which GQF-C type, GQF-Z type, GQF-L type, GQF-F type bridge expansion joints for stretching the amount of 80mm below the bridge joints, GQF-MZL-type bridge expansion joint type is by the side beams, the beam , Modular bridge expansion joint device beams and linked institutions, and for stretching the amount of 80mm-1200mm of large and medium span bridges. Installation of bridge expansion joints, bridge expansion joints performance, Hebei bridge expansion joints, install expansion joints precautions, expansion joints bridge expansion joints of construction requirements classification requires 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 mud blocked garbage; installation, inspection, maintenance, eliminate the dirt to be simple and convenient. Set expansion joints, railings and the bridge deck to be disconnected. Bridge expansion joints Products: bridge expansion joints rubber temperature range 1, bridge expansion joints using neoprene (CR) telescopic device is suitable for a temperature of -25 ℃ ~ 60 ℃. 2, bridge expansion joints using natural rubber (NR) telescopic device is suitable for a temperature of -40 ℃ ~ 60 ℃. Design and manufacture of technical conditions 1, bridge expansion joints design load: The JTJ01-88 (1995) "Highway Engineering Technical Standards" provides the car - Super 20 design load. 2, bridge expansion joints of the structure using shaped steel bridge structural steel 16MN steel tensile strength should not be less than 480Mpa; allowable bending stress is 210Mpa. 3, the structure of the bridge expansion joints branched Cheng Hengliang use 16Mn or 45 steel, which allows the bending force of 210Mpa or 220Mpa. 4, the remaining parts of steel bridge expansion joints can be used not less than A3-strength steel.
