摘要：In this study, the authors′ plan to investigate the status of steel pipe scaffolding assembled on domestic construction sites, to use specific tests to determine whether the torque of the clamps surveyed satisfies the test criteria specified in the functional examination standard of the provisional facility, to compare and analyze the marginal load of buckling using main variables (by size, construction work type) by applying the spring coefficient of the clamps as calculated using the MIDAS structural analysis program and, with all these results, to propose improvements and direction for the future. Ultimately, the goal is to establish measures to prevent accidental falls due to the collapse of improperly assembled scaffolding. The result of functional certification standard tests for clamps showed that the fastening strength of clamps on the main members (poles, wales, and joists) reached only 63.3% (13.03 average maximum load/35Nm Standard fastening strength × 100) of the standard fastening strength (35Nm), indicating that certified clamps were not used. Accordingly, there is a necessity for thorough public relations, education, guidance, and examination to allow workers to engage in safety management and understand the importance of clamp fastening strengths on outdoor steel pipe scaffolding.
