Gallop bridge expansion joint device bridge expansion joint device GQF-C type, GQF-Z type, GQF-L type, GQF-F type, GQF-MZL type is the use of all hot-rolled steel shaped the overall shape of the design of the bridge expansion joints products. Which GQF-C type, GQF-Z type, GQF-L type, GQF-F-type bridge expansion joint device for stretching the amount of 80mm below the bridge, GQF-MZL-type bridge expansion device type is by the side beams, beams, Modular expansion joints bridge expansion joint device beams and linked institutions, and for stretching the amount of 80mm-1200mm of large and medium span bridges Gallop Road and Bridge Engineering Co., Ltd is mainly engaged in construction materials highway bridges, tunnels, water conservancy, railways, etc.; Main business: bridge rubber bearings, bridge rubber inflatable mandrel, bridge expansion joints, water stop, closed-cell foam, rubber dams, ports and other road and bridge fenders and Water products. Welcome to visit our website: Hengshui Gallop Road and Bridge Engineering Co., Ltd. 24 hours of free technical advice GQF-F80 type bridge expansion joints, please contact us to discuss business, we will be happy to serve you. Contact: Zhao Jiale GQF-E-type bridge expansion joints Features: low building height, simple structure, easy installation, with significant reliability GQF-F40 type bridge expansion joints, 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 GQF-Z40 type 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 also yet to be resolved, therefore, we have to eliminate the step to prevent jumping, good road conditions, the relevant departments and construction units use a number of 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 under load at which the displacement can be achieved without generating extra additional internal forces, and to ensure smooth traffic. Domestic bridge expansion joints are usually provided at the movable end of the upper structure and abutments, and convergence at the Joint superstructure. GQF-F80 type bridge expansion joints, expansion joints, bridge expansion joint device 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) strong, credible, Hebei Hengshui in other industries has accumulated a large number of loyal customers.
