FUNDAMENTAL STUDY ON THE RISK OF ASSEMBLING AND DISMANTLING WORK OF THE SCAFFOLDS UNDER STRONG WIND

Abstract

The weather has a great influence on the construction work, and the construction accidents sometimes happened due to the bad weather, e.g. strong wind. Therefore, wind-induced structural accidents during construction were investigated on the basis of the yearbooks of the Japan Construction Safety and Health Association, and it was found that the death accidents happened mostly by the falling dawn of the workers. Therefore, to prevent these accidents, experiments to the subjects were performed on the risk of the assembling and dismantling work of the scaffolds under strong wind. 10 construction workers were joined in the experiments, and the assembling and dismantling work were carried out in the wind tunnel under strong wind. From the results obtained, it was found that there was a high risk in the assembling and dismantling work of the scaffolds even under 10 m/s at the mean wind speed, which was the standard of the work stopping by the law of the Labor Safety and Sanitation.
