SEALING DEVICE FOR BUS DUCT, AND PENETRATION PART STRUCTURE
PROBLEM TO BE SOLVED: To provide a sealing device for a bus duct capable of improving a sealing performance in the case of fire between the bus duct that penetrates a partition wall for separating a fire zone and the partition wall, and a penetration part structure.SOLUTION: In a sealing device 10, a frame material 12 of a holding member 11 configured by welding steel materials having L-shaped and Z-shaped cross sections is provided while surrounding an outer peripheral part of a bus duct 4 which penetrates a fireproofing wall 1 as a partition wall and of which the cross section is rectangular. The frame material 12 is fixed to the bus duct 4 by a bolt 14, and an accommodation part 13 is formed between the frame material and the bus duct 4. In the accommodation part 13, an incombustible blanket 18 having elasticity is accommodated while being compressed so as to be elastically deformed and seal a gap between the holding member 11 and the bus duct 4 and a gap between the bus duct 4 and the incombustible wall 1 or mortar 2. Even if a fire occurs in a fire zone and the bus duct 4 is deformed, the incombustible blanket 18 is elastically deformed and prevents a gap from being generated, such that the sealing performance is improved.SELECTED DRAWING: Figure 1
【課題】火災区域を分離する隔壁を貫通するバスダクトと前記隔壁との間の、火災時における封止性能を向上させることのできるバスダクトの封止装置及び貫通部構造を得る。【解決手段】封止装置１０は、断面がＬ形とＺ形の鋼材を溶接して構成された保持部材１１の枠材１２が隔壁としての耐火壁１を貫通する断面矩形のバスダクト４の外周部を取り囲んで設けられるとともに、枠材１２がボルト１４にてバスダクト４に固定され、バスダクト４との間に収容部１３を形成している。収容部１３には、弾性を有する不燃性ブランケット１８が弾性変形可能にかつ保持部材１１とバスダクト４との間の隙間およびバスダクト４と耐火壁１あるいはモルタル２との間の隙間を封止するようにして圧縮された状態で収容され、火災区域に火災が発生してバスダクト４が変形しても、不燃性ブランケット１８が弾性変形して隙間が生じるのを防止するので、封止性能が向上する。【選択図】図１
