FIREPROOF DUCT, METHOD FOR USING THE FIREPROOF DUCT, FIREPROOF STRUCTURE USING THE FIREPROOF DUCT AND METHOD FOR MANUFACTURING THE FIREPROOF DUCT
To solve conventional problems on a construction aspect and cost as a configuration and method for reducing deterioration of fire resistance caused by forming a through hole on a wood member, and then provide a fireproof duct capable of simply and inexpensively providing a configuration and method for reducing deterioration of fire resistance cased by forming a through hole on a wood member.SOLUTION: A fireproof duct 1 of the present invention comprises a metal inside duct 2, a metal outside duct 3, and a fireproof material 4 provided between an outer peripheral surface 2b of the inside duct 2 and an inner peripheral surface 3a of the outside duct 3.SELECTED DRAWING: Figure 1
【課題】従来、木製部材に貫通孔を形成することによる耐火性の低下を低減する構成及び方法としては、施工面、コスト面等での課題があった。そこで、本発明は、木製部材に貫通孔を形成することによる耐火性の低下を低減する構成及び方法を、簡単かつ安価に提供できる耐火ダクト等を得ることを目的とする。【解決手段】本発明に係る耐火ダクト１は、金属製の内側ダクト２と、金属製の外側ダクト３と、内側ダクト２の外周面２ｂと外側ダクト３の内周面３ａとの間に設けられた耐火材４とを備えたことを特徴とする。【選択図】図１
