Securing the quality of the temporary structure at the construction site is a very important factor in securing the quality of the structure and safety of workers. Nevertheless, a considerable number of construction materials are reused without proper quality control, which threatens not only the quality of the structure but also the safety of the construction. In particular, the degree of defective pipe supports is very serious. Therefore, the purpose of this study was to present a reasonable method for repair or supplement quality control to ensure the quality of reused pipe supports through performance tests. As a result of the study, the pipe support is composed of a combination of various parts, and it is necessary to dispose of the product which is worn out significantly by the male screw, and to repair the inner pipe, it is difficult to secure the overlapping length. In addition, quality control through repair and supplementation seems to be more important than replacement or repair of any part.
