PENETRATION PART STRUCTURE OF BATH DUCT, AND CONSTRUCTION METHOD FOR PENETRATION PART STRUCTURE OF BATH DUCT
PROBLEM TO BE SOLVED: To provide a penetration part structure of a bath duct capable of assuring flame shielding performance of a penetration part where the bath duct passes through a partition wall separating a fire area.SOLUTION: A sheet-like silica cloth is wound around an outer peripheral part of a case 4a of a bath duct 4 by several times, there is provided an end part 13a bent outward in a direction of section of the case 4a, a flame shielding member 13 formed in an annular shape is formed, the end part 13a is adhered and fixed by an adhesive tape 17 against a fire-proof wall 1, and the other end 13b is adhered and fixed to the case 4a by an adhesive tape 18. With this arrangement as above, the flame shielding performance can be assured even if a clearance is present between the open hole forming part [1a] and the case 4a or the case 4a is curved and deformed due to heat at the time of fire and a clearance is formed.SELECTED DRAWING: Figure 1
【課題】火災区域を分離する隔壁をバスダクトが貫通する貫通部の遮炎性能を確保できるバスダクトの貫通部構造を得る。【解決手段】バスダクト４のケース４ａの外周部にシート状のシリカクロスを複数回巻回して、ケース４ａの断面方向外方に折り曲げられた端部１３ａを有し、環状に形成された遮炎部材１３を形成し、端部１３ａを粘着テープ１７で耐火壁１に接着固定し、他方の端部１３ｂは粘着テープ１８にてケース４ａに接着固定する。これにより、貫通孔形成部（１ａとケース４ａとの間に隙間があったり、火災時の熱によりケース４ａが湾曲変形して隙間ができても遮炎性能を確保できる。【選択図】図１
