The steel pipe scaffolding, which is one of the most commonly used construction structures in construction sites, should be installed with a wale spacing of 1.5 m or less in accordance with the regulations on occupational safety and health standards, and the first wale should be installed 2.0 m or less from the ground. However, when considering the average height of adult men and women, if the vertical wale spacing is 1.5m and the work-plate is installed, the work height is limited to within 1.5m, which is very inefficient for work. If the vertical wale spacing is 3.0m and work-plate is installed, it exceeds the work height and range of the worker. Therefore, the ladder scaffold etc. must be installed on the work-plate, which leads to an increase in inefficient work and accident risk. In addition, most of the foreign country wale spacings are defined to be less than 2.0 m, and it is necessary to review the wale spacing considering the work environment of the worker in Korea. Therefore, in this study, the structure analysis according to the wale spacing was performed and structural safety was checked for proper wale spacing when considering the elongation of korean adult workers. |
