Bridge expansion joints with cheap looking Hebei military bridge rubber bearing long telephone 18131812893 bridge expansion joints refers to the deformation of the bridge to meet the requirements, generally between the two ends of the beam between the end of the beam or bridge abutment and articulation Expansion Joint position. 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 , to be simple and easy to eliminate dirt. Set expansion joints, railings and the bridge deck to be disconnected. Expansion joints Type 1) galvanized sheet steel joints. Fabricated in small and medium-span girders bridge, when the beam deformation within 20-40mm often choose. 2) Steel joints: its structure is more complex, only on a larger temperature difference between regions or large span bridge was adopted. Steel expansion joints are also appropriate for use on the bridge of. 3) rubber expansion joints. It is a rubber band as a cross stitch material. This expansion joint structure is simple, easy to use, the effect is. A large amount of deformation in the larger span bridge, you can use a combination of rubber and steel joints. Model joints expansion joints in accordance with performance and installation methods can be divided into: GQF-C type, GQF-Z type, GQF-L type, GQF-F type which GQF-MZL number of model type bridge expansion joint device is the use of hot-rolled overall Bridge expansion joint device forming shaped steel design. GQF-C type, GQF-Z type, GQF-L type, GQF-F-type expansion joint device for stretching the amount of 80mm below the bridge joints. GQF-MZL-type expansion joint device is Modular bridge expansion joint device by the side beams, beams, beams and linked institutions, and for stretching the amount of 80mm-1200mm of large and medium span bridges ..
