Claims (6)
- 扁平な上部空間を持つ消火対象物の上面に、消火砂を均一に放射するための消火用ノズルであって、消火砂をガス圧によって放射する扁平なノズル本体の先端部の外側に、扁平なノズル本体の先端から放射される消火砂の進行方向を下向きに変更し、消火砂を消火対象物の上面に向かって斜め下方に吹き付けてバウンドさせる偏向板を全幅にわたり設けたことを特徴とする消火用ノズル。
- 扁平なノズル本体の下面に、ノズル本体の位置決め用凹部を備えたガイド板を設けたことを特徴とする請求項1記載の消火用ノズル。
- 前記偏向板は、消火対象物の上面に対して30〜45度の下向き角度を持つことを特徴とする請求項1記載の消火用ノズル。
- ノズル本体の基部が斜め下向きに屈曲され、その下端に消火砂をガス圧により供給する金属パイプの接続部を形成したことを特徴とする請求項1記載の消火用ノズル。
- 請求項1記載の消火用ノズルを用いた消火方法であって、消火対象物の上面に形成された扁平な上部空間の一端からノズル本体を消火対象物上面の端部まで差し込み、ノズル本体の先端部からガス圧によって放射される消火砂を偏向板によって斜め下方に吹き付け、消火対象物の上面でバウンドさせながら奥側まで分散させることを特徴とする消火方法。
- 消火砂が蛭石であることを特徴とする請求項5記載の消火方法。
