ATTIC VENTILATION STRUCTURE AND VENTILATION MEMBER
PROBLEM TO BE SOLVED: To provide an attic ventilation structure capable of reducing the expansion of combustion, by restraining the expansion of the combustion to a sheathing roof board in a fire.SOLUTION: An attic ventilation structure comprises a roof backing 3, a sheathing roof board 4 placed on the roof backing 3, a vertical plate material 6 fixed to the roof backing 3 and a ventilation member 10 provided between the vertical plate material 6 and the sheathing roof board 4 and having a ventilation passage for communicating an attic and outside air. The vertical plate material 6 is arranged so as to form a clearance between the sheathing roof board 4 and itself, and the ventilation member 10 comprises a ventilation part 14 for forming the ventilation passage and a fireproof part 15 arranged so as to cover a sheathing roof board surface by contacting with the sheathing roof board 4 and storing a fireproof member 18 on the inside by being partitioned from the ventilation part 14.SELECTED DRAWING: Figure 3
【課題】 火災時に野地板への燃焼の広がりを抑え、燃焼の拡大を軽減させることができる屋根裏換気構造を提供する【解決手段】 屋根下地３と、前記屋根下地３に載置される野地板４と、前記屋根下地３に固定される縦板材６と、前記縦板材６と前記野地板４との間に設けられ屋根裏と外気とを連通する通気経路を備えた通気部材１０とを備える屋根裏換気構造である。前記縦板材６は、前記野地板４との間に隙間を形成するように配置され、前記通気部材１０は、前記通気経路を形成する通気部１４と、前記野地板４に接触して前記野地板表面を被覆するように配置され、前記通気部１４と仕切られて内部に耐火部材１８を収納する耐火部１５と、を備える。【選択図】 図３
