FLAME-SHIELDING DEVICE OF PIPE-PENETRATING PART
To provide a flame-shielding device of a pipe-penetrating part which can tightly cover an opened pipe-penetrating part in the event of fire disaster, and which does not cover an inflammable pipe by a self-weight of a structure covering the opening at a normal time.SOLUTION: The present invention includes: a support steel material 16 that sandwiches a pipe-penetrating part 6 of a wall 1 from both sides in a horizontal direction; and a non-inflammable cover mechanism 14 having at least two non-inflammable covers 10, a roller 11, and a meltable stopper 19. The support steel material 16 includes a guide 15 extending in a vertical direction. The non-inflammable covers 10 are connected to each other in a vertical direction. A non-inflammable covers 10a is fixed to the support steel material 16, and a non-inflammable cover 10b is connected to the roller 11. The roller 11 is positioned in the guide 15. In the meltable stopper 19, at a normal time, a meltable member supports the roller 11 above the pipe-penetrating part 6. In the event of fire disaster, the meltable member melts or burns, the roller 11 moves downward below the pipe-penetrating part 6, and the non-inflammable covers 10 cover the pipe-penetrating part 6.SELECTED DRAWING: Figure 1A
【課題】火災発生時には開口した配管貫通部を隙間なく覆うことができ、通常時には開口部を覆う構造物の自重が可燃性配管に掛からない、配管貫通部の遮炎装置を提供する。【解決手段】壁１の配管貫通部６を水平方向の両側から挟む支持鋼材１６と、少なくとも２つの不燃材カバー１０とローラー１１と溶融性ストッパ１９を備える不燃材カバー機構１４を備える。支持鋼材１６は、上下方向に延伸するガイド１５を備える。不燃材カバー１０は、上下方向に互いに接続される。不燃材カバー１０ａは支持鋼材１６に固定され、不燃材カバー１０ｂにはローラー１１が接続される。ローラー１１は、ガイド１５の中に位置する。溶融性ストッパ１９は、通常時では溶融性部材がローラー１１を配管貫通部６よりも上側で支持する。火災発生時には、溶融性部材は、溶融または焼失し、ローラー１１は、配管貫通部６よりも下側に移動し、不燃材カバー１０は、配管貫通部６を覆う。【選択図】図１Ａ
