Our company is the specialist in producing expansion joint, include expressway bridge expansion joint and railway bridge expansion joint device. Expressway bridge joints include rubber strip type, BF complex plate type, SF trinal-protection expansion device, Cd, Fd, Fm type expansion joint device, modular expansion joint device, polymeric spring expansion joint device; railway bridge expansion joint devices include weatherize steel expansion joint device and aluminum alloy expansion joint device.
Every kind of expansion joint device introduction as follows.
Rubber strip expansion joint device is fit for express bridge project of the movement less than 50mm; BF complex plate expansion joint device is fit for express bridge project of the movement less than 200mm; SF trinal-protection expansion device is fit for middle, big span bridge project. Cd,Fd,Fm expansion joint devices are fit for express bridge project of the movement less than 80mm;
GQF-MZL and XF types of expansion joint devices comprised by profiled bar and rubber strip sealing and movement control system are fit for movements between 80-1200mm, polymeric spring expansion joint device which use polymeric to let the every movement same is fit for movements between 80-1200mm, and have lower height in structure.
Railway expansion joint device is important joint between the bridge girder ports, and plays important role in expansion of bridge girder and watertight. Considering of lasting requirement, choosing weatherize steel and aluminum alloy can promote the weatherize character; watertight strip with the trunk shape, if curved girder port gap could not use trunk shape strip, we can use strip shape. Railway bridge expansion joint device could not stand the direct force of wheel, without considering load, the height of weatherize expansion joint device is only 38mm, the height of aluminum alloy expansion joint device is only 40mm, we can install the joint very easily in the bridge protection deck, not need set a gap in the girder.
Except for these, our company has studied TKSSF series railway expansion joint device by ourselves, and got the patent. |
