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 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 with their contact SF comb. steel telescopic device (comb-shaped joints) Specification: 1) stretching large, shallow buried steel comb-shaped expansion joint device is designed to allow expansion volume 40 ~ 1000mm for a variety of non-current beam structure, different span New Bridge and Old Bridge Reconstruction XF Modular expansion joints, expansion capacity, a wide range. Comb-shaped steel expansion joint device, the overall structural height 30 ~ 40mm. Each end of the beam without changing the original structure, shallow buried anchor strength can be achieved effectively. In general, the amount of stretching> 80mm later, other types of telescopic device overall height high, shaped steel telescopic device overall height> 250mm. Design must be the end of the beam structure for special treatment, while increasing the difficulty of construction and therefore, telescopic large, shallow buried telescopic device clearly showing that this unique technological advantage. 2) Comb type automatic slag gap stretching all the different types of telescopic device, the prevalence of a common problem. There are gaps in the telescopic ash, hard blockage, seriously affecting the normal time of the telescopic beam. Steel comb-shaped expansion joint device, due to the special processing structure, located on one side comb gap telescopic beam end face, while the bottom surface of the comb-shaped stainless steel slider cushion, ash and hard objects can only be left on the surface, this can aid comb-shaped steel expansion process and the role of the vehicle, automatically ash, hard stretch exhaust gap, so as not to cause congestion, without manual cleaning GQF-L-type shaped steel bridge expansion joints, without affecting the normal of telescoping beam . 3) has excellent waterproof, dustproof performance. Comb-shaped steel expansion joint device settings Layer neoprene waterproof layer, waterproof ointment joints and watering in the comb-type steel telescopic gap, achieve excellent waterproof and dustproof role GQF-F-type shaped steel bridge expansion joints, effective protect the bridge structure and delay bearing corrosion and prolong the life of the bridge. 4.) telescopic device and the road overall performance is good steel comb-shaped device using flex-rigid joints and other measures to eliminate the condition more thoroughly Jump in the car driving from the structure, telescopic device uses high-grade strip on both sides Rigid concrete protection, good rigidity. Thus, the vehicle stable, no shock and vibration, reducing the impact of the bridge, reduce noise and prolong the useful life of bridges and vehicles.
