ウォークスルー型シートシャッターの避難安全性の実験的検討 : 流動性,視認性と操作性

Abstract

The purpose of this paper is to clarify the refuge safety of the sheet shutter. Three kinds of experiments were performed and analyzed by five viewpoints; visual recognition, operation, quantity of human flow, safety, durability. The quantity of human flow, visual recognition, and operation are described in this paper. The results are summarized as follows. 1) The sheet shutter satisfies the necessary flow coefficient of 1.5 persons/m・s which was estimated in case of a fire. 2) Mental evaluation of a sheet shutter is lower than a fire door. 3) It is difficult for wheel chairs to pass through as the passage is narrow. 4) The optimum point at which to push the sheet shutter is not in a suitable position for tall people.
