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 shaped steel hot rolled all the overall shape of the design of 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 joints GQF, GQF-MZL-type bridge expansion type is by the side beams, Modular bridge expansion joint device beams, 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 engineering 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, harbor bridge and Water fenders and other products.

Contact: Zhaojia Le 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 Simple 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 expansion joints, 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, easy to use single-slotted joints, good effect. A large amount of deformation in the larger span of the bridge, 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.
