Gallop Bridge bridge expansion joints refers to the deformation of the bridge to meet the requirements, usually between two end of the beam, or set the position articulated joints on the bridge between the end of the beam and abutment. 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 bridge expansion joints in accordance with the performance and installation methods can be divided into: GQF-C type, GQF-Z type, GQF-L type, GQF-F type bridge expansion joints . Wherein Gallop GQF-MZL number of model type bridge expansion joint device GQF-D60 type bridge expansion joints, is the use of hot-rolled steel bridge expansion joint device shaped the overall shape of the design. Bridge 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 by the side beams, beams, Modular bridge expansion joint device beams and linked institutions, and for stretching the amount of 80mm-1200mm of large and medium span bridges. Gallop bridge expansion into: Modular bridge expansion joints and KS devices and TST thermoplastic elastomer bridge expansion joint device of the present article by the Hengshui Gallop Road and Bridge Engineering Co., Ltd. Document if necessary, please log in to contact 80 telescopic. seam 80 expansion joint must be carried out before installing the proper handling, we must ensure that the flat hanging flat, if not immediately install 80 expansion joint expansion joints, bridge expansion joints need to be placed in the appropriate skids ensure expansion joints flatness. The protection should be given to ensure that the expansion joint cover ways to avoid sun exposure and snow and rain, to prevent excessive deformation of joints simultaneously and not in contact with other harmful substances. Joints in the factory to be protective treatment, prior to assembly to the oxide surface of steel components, the grease cleaned GQF-D40 type bridge expansion joints, we must strengthen the welds of preprocessing. Ensure the quality of expansion joints, single slit steel, bearing boxes of steel, steel beam, side beam, and the anchor plate exposed surface coating requirements are as follows: epoxy zinc-rich primer thickness of 60μm; epoxy micaceous iron oxide intermediate thickness 70μm; acrylic aliphatic polyurethane topcoat thickness of 2 × 35μm. Paint requires no wrinkling, sagging and good adhesion. 80 expansion joints must be in place to detect include modulus telescopic device clinch rubber bearings and bearing the physical and mechanical properties testing of pressure to meet the requirements, as well as check Check sealing strips, roads and bridges through routine maintenance Work should be cleaned regularly with a rubber seal in the accumulation of sediment, stone chips and other debris GQF-D80 type bridge expansion joints, flexible and expandable and prevent damage to the seal belt of the telescopic device by force, resulting in leaks. Should always check the telescopic device top surface is smooth, such as abnormal uneven phenomenon may be sliding bearing or pressed bearing damage. If damaged parts should be replaced. Always check the seal if damage occurs on a regular basis to maintain the seal, found a gap in the expansion joint sealing strips have gravel and dirt, then to promptly clean up; to different periods of 80 joints for maintenance and inspection, while under rainy day to go to the bridge to see if there is leakage phenomenon, found the seal broken or off, to be replaced or re-install the seal off position.
