Description

technical field [0001] The invention relates to the technical field of hammering of steel components, in particular to a hammering device for improving the fatigue performance of components. Background technique [0002] Steel components are widely used in long-span bridges due to their light weight, large ultimate bearing capacity, and short construction period. The steel box girder business in my country started relatively late but developed rapidly. At present, orthotropic steel is commonly used in domestic bridges. Bridge deck and other steel structures. Due to the complex structure of the steel structure and welding defects, coupled with the continuous growth of traffic volume in my country at this stage, the steel bridges built in the early stage have fatigue problems to varying degrees. [0003] When steel component testing or maintenance personnel perform hammering tests and hammering maintenance on steel components, when using hammering devices to hammer test pieces...
