FIRE SPARK DETECTION METHOD AND FIRE SPARK DETECTION SHEET
To provide a fire spark detection method capable of detecting coming of fire sparks in simple configuration, and a fire spark detection sheet.SOLUTION: A detection sheet 10 comprises a sheet-shaped detection member 11 and a fire-retardant protection member 15. The detection member 11 is formed from a synthetic resin by providing a space 11s between a first surface 11a which is molten by heat of fire sparks and on which a hole is formed, and a second surface 11b at an opposite side of the first surface 11a. A state change of the space 11s is detected by the hole formed in the detection member 11 by coming of the fire sparks.SELECTED DRAWING: Figure 1
【課題】簡単な構成で火の粉の飛来を検知することができる火の粉検知方法及び火の粉検知シートを提供する。【解決手段】検知シート１０は、シート状の検知部材１１及び難燃性の防護部材１５を備える。検知部材１１は、火の粉の熱によって溶けて孔が形成される第１表面１１ａと、第１表面１１ａの反対側の第２表面１１ｂとの間に空間１１ｓを設け、合成樹脂で形成される。火の粉の飛来によって検知部材１１に形成された孔により空間１１ｓの状態変化を検知する。【選択図】図１
