Sliding surface or rolling surface corrosion of the main reasons for the deck, defense, poor drainage-way truss supports, causing water to enter the sliding surface or rolling surface corrosion. Hinges and rollers main reason for cracking, such as to limit the transverse hinge or central part in a two-way grid when roller bearings, if one side is relying too close to cracking. Crack and fall off the roll axis, due to shrinkage of concrete, creep displacement of more than design, aging and cracking, aging and cracking of rubber bearing steel grid bearing the main beam chassis construction or bad In individual position over compression cracks. Bearing steel grid strict quality control process causes early aging of rubber, rubber layer cracking, spalling. Lifting means deformation, mainly because of the deformation floating means hands over the role of the complex bridge design to withstand the force and displacement of the deformation. Deformation limit device, the deformation of the main stopper, steel grid bearing selection and arrangement inappropriate grid ball bearings, the shrinkage of the concrete bridge, creep generate additional shrinkage. Construction error generated during deformation, the same support line set up multiple steel grid bearing, due to the gap between the upper and lower transverse bearing inconsistent concentrated force acting on a bearing and deformation. Prestressed concrete bridge of the Bay Bridge or the occasion, because of the tension caused by the compression volume control is not good, displacement restrained steel grid bearing upturned deformation. Re-coating protective steel grid bearing, the material world is facing a serious problem of corrosion, the corrosion not only consumes valuable asset of human creativity, and undermine the normal operation of production and life, and many other activities. Relationship corrosion and environmental pollution are increasingly a cause for concern, steel grid bearing steel components, especially steel grid bearing grid bearing, due to the environment would have been affected by corrosion, if severe corrosion not only reduce its function, and will directly affect the normal use of bearing, metal protective coating to protect the most direct and simple, the best a means to re-paint protection steel grid bearing, but also a bridge Maintenance of a work management often happens. Replace the protective coating construction process, the bottom surface of the paint coating is the main reason for the durability of impact, so before replacing the paint, steel grid bearing of choice should be the old part of the aging layer and completely remove rust, know to meet the requirements so far When, when replacing the protective coating, commonly used injection method, steel truss bearing if two other construction methods should not affect the damage of surrounding components, specific reference to the relevant requirements of the coating can be protective coating construction process.
