FIRE PROTECTION METHOD AND FIRE PROTECTION STRUCTURE
To provide a fir protection technology which provides a function for preventing propagation of fire to an adjacent area to a resin pipeline without spending a lot of time and money.SOLUTION: In a fire protection structure 10, a local portion of a resin pipe exposed to a space V is cut and a reciprocal flame prevention member 22 is attached to one end of a steel pipe 21 which replaces the cut local portion. The other end of the steel pipe 21 to which the reciprocal flame prevention member 21 is attached is connected with a tip of a first remaining pipe 11, and a tip of the reciprocal flame prevention member 22 is connected with a tip of a second resin pipe 12. A support member 32 is installed on an inner surface of the space V and the steel pipe 21 is supported by the support member 32. A fire-resistant material 36 is attached to a periphery of the first remaining pipe 11.SELECTED DRAWING: Figure 7
【課題】費用と期間をかけずに、隣接する区域に火災を伝播させない機能が、樹脂製の配管に付与される火災防護技術を提供する。【解決手段】火災防護構造１０において、空間Ｖに露出する樹脂管の局所部分が切断され、切断した前記局所部分を代替させる鋼管２１の一端に逆炎防止部材２２が取り付けられ、この逆炎防止部材２１を取り付けた鋼管２１の他端が第１残存管１１の先端に接続され、逆炎防止部材２２の先端が第２樹脂管１２の先端に接続され、空間Ｖの内側面に支持部材３２が設置され、支持部材３２に鋼管２１が支持され、第１残存管１１の周囲に耐火材３６が装着された、ことを特徴とする。【選択図】 図７
