CONSTRUCTION METHOD FOR FIRE RESISTANT STRUCTURE OF PENETRATION PART IN COMPARTMENT BODY OF BUILDING

摘要

PROBLEM TO BE SOLVED: To provide a construction method for a fire resistant structure of a penetration part capable of easily filling a through-hole with a fire-resistant resin composition.SOLUTION: A construction method for a fire resistant structure of a penetration part in a compartment body of a building, including a through-hole 2 into which a pipe or a cable 4 is inserted includes: a surrounding process for surrounding an outer periphery of the pipe or cable 4 with a foam 5 consisting of a fire-resistant resin composition including thermally expandable graphite outside the through-hole 2; and a moving process for moving the foam 5 surrounding the pipe or cable 4 inside the through-hole 2.SELECTED DRAWING: Figure 1
