GQF-E80-type bridge expansion joints large exposure internal price, details inquire Wie military bridge, bridge expansion joints of construction requirements requires expansion joints in parallel, perpendicular to the axis of the bridge in both directions, can freely scalable, secure and reliable vehicles should be smooth with 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. Situation bridge expansion joint development is well known, temperature changes, shrinkage and creep of concrete, uneven foundation settlement, under the influence of vehicle load, bridge length will change, so that the end of the beam is displaced to accommodate this shift and to maintain traffic smooth, it must set the bridge expansion joint device. Thus, the role of bridge expansion joints, is to adjust the displacement between the upper structure by temperature changes, vehicle load environmental characteristics and physical properties of construction materials caused. In general, the joints should have good durability, ride comfort, good water resistance, ease of construction, simplicity of daily delivery company Hunan: Changsha, Hengyang, Shaoyang, Zhuzhou, Xiangtan, Yueyang, Changde, Yiyang, Chenzhou, Yongzhou Huaihua, Loudi, Zhangjiajie Hunan, Guangdong: Guangzhou Shenzhen, Zhuhai, Shantou, Shaoguan, Huizhou, Foshan, Jiangmen, Zhaoqing, Maoming, Yangjiang, Meizhou, Shanwei, Heyuan, Qingyuan, Dongguan, Zhongshan, Chaozhou, Jieyang, Yunfu, Guangxi: Nanning, Liuzhou, Guilin, Wuzhou, Beihai, Qinzhou Fangchenggang Guigang Yulin, Baise, Hechi Hezhou guest Chongzuo Hainan: Haikou, Sanya, Southwest Region, Sichuan: Chengdu, Deyang, Mianyang, Zigong, Panzhihua, Luzhou Guangyuan, Suining, Neijiang, Leshan, Nanchong, Yibin Kwong in Ziyang Florida Ya Anba Meishan Ganzi Aba Liangshan
