摘要

PROBLEM TO BE SOLVED: To provide a cover member for a section penetration part, which enables work to be easily executed in a short period of time and which sufficiently exerts fire resistance efficiency.SOLUTION: A cover member 1 for a section penetration part having a through-hole 14 provided in a section body of a building includes: a band part 2; an annular body 4 which is attached to the band part 2 at a first end 3 and which can be expanded in a radial direction toward a second end 7 on the opposite side of the first end 3 from the first end 3; and a thermally-expansible filler 10 which is attached to the first end 3 of the band part 2 or the annular body 4, or the vicinity of the first end.SELECTED DRAWING: Figure 2
