Abstract
As of July 1, 2017, the method of quality management of construction equipment had been changed completely. In case of manufacturing and distributing pipe supports, the support length according to the safety certification standard shall be not more than 6 m and the compressive strength shall be not less than 40,000 N at the maximum height. However, the field tests for the quality control standard were usually performed at 3.5 m when the length of the pipe supports is 3.5 m to 4.0 m, and the compression strength was specified to be more than 35,300 N. This difference in the two standards can cause confusion in practice. In this study, the compression load of the pipe supports was tested and found to be more than 30% defective. Therefore, it is necessary to review the modification of the safety certification and quality standards to improve the standard requirements.
