FIRE-RESISTANT EXTERIOR WALL STRUCTURE FOR WOODEN BUILDING
PROBLEM TO BE SOLVED: To provide a fire-resistant exterior wall structure for a wooden building having fireproof performance, easily constructed and inexpensively built.SOLUTION: A fire-resistant exterior wall structure 1 includes a structural face material 24 attached to an outdoor side of a structural member 2 constituted with wood, a furring strip material 42a attached to an outdoor side face of the structural face material 24, and a lightweight cellular concrete panel 44 attached to an outdoor side face of the furring strip material 42a. The lightweight cellular concrete panel 44 has density d of 200 kg/mor more and 550 kg/mor less, a thickness t of 45 mm or more and 100 mm or less, and an ignition loss value α of 5 wt.% or more and 15 wt.% or less, and a value of d(kg/m)×t(mm)×α(wt.%)÷100000 is 3000 or more and 30000 or less, and contains a radiant heat absorbing reflection component of 1 wt.% or more and 20 wt.% or less to the total solid content constituting a panel body part 44a.
【課題】耐火性能を有し、施工が容易であると共に低コストの木造建築物の耐火外壁構造を提供することを目的とする。【解決手段】耐火外壁構造１は、木材で構成された構造部材２の屋外側に取り付けられた構造用面材２４と、構造用面材２４の屋外側の面に取り付けられた胴縁材４２ａと、胴縁材４２ａの屋外側の面に取り付けられた軽量気泡コンクリートパネル４４と、を備えている。軽量気泡コンクリートパネル４４は、密度ｄが２００ｋｇ／ｍ３以上５５０ｋｇ／ｍ３以下であり、かつ厚さｔが４５ｍｍ以上１００ｍｍ以下であり、かつ強熱減量値αが５ｗｔ％以上１５ｗｔ％以下であり、かつｄ（ｋｇ／ｍ３）?ｔ３（ｍｍ３）?α（ｗｔ％）?１０００００の値が３０００以上、３００００以下であり、かつパネル本体部４４ａを構成する全固形分に対して、輻射熱吸収反射成分を１ｗｔ％以上、２０ｗｔ％以下含有する。【選択図】図１
