FIRE-RESISTING FILLING STRUCTURE
PROBLEM TO BE SOLVED: To provide a fire-resisting filling structure preventing passage of fire in a partition through hole even when an earthquake occurs, and retaining fire-resisting properties.SOLUTION: A fire-resisting filling structure 1 which comprises a sleeve 2 for forming a partition through hole 6 on the floor or wall of an architectural structure, and a piping 8 inserted into the sleeve 2 includes: a lid material 10 mounted on the sleeve 2 or the piping 8 in a clearance between the sleeve 2 and the piping 8 so as to fill the clearance, or a lid material 10 filled in the clearance so as to fill the clearance between the sleeve 2 and the piping 8. When an initial thickness of a part of the lid material 10 arranged in the clearance is t1, and a thickness after a compression fatigue strength test is t2, the lid material 10 satisfies the relational expression of 0.5<(t2/t1)<1.SELECTED DRAWING: Figure 1
【課題】地震が起きても区画貫通孔における火災の通過を防ぎ、耐火性が維持された耐火充填構造を提供すること。【解決手段】建築物の床または壁に区画貫通孔６を形成するためのスリーブ２と、スリーブ２内に挿通された配管８とを備えた耐火充填構造１は、スリーブ２と配管８の隙間を埋めるように該隙間内でスリーブ２又は配管８に装着された蓋材１０、又はスリーブ２と配管８の隙間を埋めるように該隙間に充填された蓋材１０を備え、蓋材１０が、該隙間に配置される蓋材１０の部分の初期厚みをｔ１、圧縮疲労強度試験後の厚みをｔ２とした時に、０．５＜（ｔ２／ｔ１）＜１ の関係式を満たすことを特徴とする。【選択図】図１
