Description
軸組:SS400,C−60×40×10×3.2mm
試験体の大きさ:1,600mm×1,000mmの矩形状
前記構成で、建築基準法第2条第八号(防火構造)の規定に基づく防火性能試験を30分間行った。この防火性能試験では、火災時における外壁の屋外側からの火熱を想定して、加熱炉により試験体表面の全面に所定温度の時間変化をほぼ一様に与え、試験体の裏面温度(外壁面の屋内側の温度上昇)を測定した。

7 防火目地
Claims (1)
- 10mm以上の板厚を有する集成材を少なくとも3層に積層して30mm以上の厚さを確保するように形成した下地材を用い、この下地材の外側面に、防風防水透湿シートが張設されるとともに複数本の胴縁が配設され、前記胴縁は通気性および排水性を確保する通気凹部が設けられており、無垢材からなる外壁仕上げ材が合决り状に接合されて前記胴縁を介して下地材の外側に張設されて、前記下地材の厚みにより防火性および耐火性を備えたことを特徴とする木質外壁の防耐火構造。
