FIRE RESISTANT STRUCTURE OF WOODEN BUILDING AND CONSTRUCTION METHOD THEREFOR
To provide a fire resistant structure of a wooden building which has small sectional area.SOLUTION: A fire resistant structure of a wooden building comprises: cedar laminate lumber (pillar) of 300×300 mm in cross-sectional size as load bearing lumber 2; sheet type rock wool of 1.5 mm in thickness as a sheet type inorganic fiber layer 3 provided outside the cedar laminate lumber; aluminum foil of 20 μm in thickness as a radiation heat reflection layer 4 which is provided outside the sheet type rock wool and reflects radiation heat; a sheet of 5 mm in thickness containing ammonium polyphosphate and vinyl acetate copolymer resin as a heat foaming layer provided outside the aluminum foil and foaming at 200°C to develop heat insulation; and (5) cypress lumbering of 19 mm in thickness as a decorative material provided outside the foaming type heat resistant coating sheet.SELECTED DRAWING: Figure 1
【課題】断面積の小さな木造建築物の耐火構造を提供する。【解決手段】荷重支持木材２としての断面寸法３００ｍｍ×３００ｍｍのスギ集成材（柱）と、該スギ集成材の外側に設けられたシート状無機繊維層３としての厚さ１．５ｍｍのシート状ロックウールと、該シート状ロックウールの外側に設けられた輻射熱を反射する輻射熱反射層４としての厚さ２０μｍのアルミニウムはくと、該アルミニウムはくの外側に設けられた２００℃以上で発泡して断熱性を発現する加熱発泡層としての厚さ５ｍｍのポリリン酸アンモニウムと酢酸ビニル共重合樹脂とを含有するシートと、（５）該発泡形耐火被覆シートの外側に設けられた化粧材としての厚さ１９ｍｍのヒノキ製材とが備えられている。【選択図】図１
