Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel structure bridge processing and manufacturing, and in particular to a safety guardrail device for high-altitude operations on steel bridges. Background Technology
[0002] This utility model relates to the field of steel structure bridge assembly, welding, and painting technology. During the manufacturing process of steel bridges in the factory, operations such as the positioning and welding of shear studs and the painting of steel beams involve working at heights, requiring the construction of safety work platforms and protective railing cables. These are typically constructed using assembled and welded profiles, resulting in low platform and railing reuse rates, significant material waste, and spot welding to the steel beams damaging the base steel material, leading to additional repair procedures and costs. Traditional construction methods are time-consuming and costly. This utility model's safety railing device effectively solves the above problems.
