Title:
COMPARTMENT PENETRATION PROCESSING STRUCTURE, COMPARTMENT PENETRATION PROCESSING MATERIAL, AND METHOD FOR CONSTRUCTING COMPARTMENT PENETRATION PROCESSING STRUCTURE
Document Type and Number:
Japanese Patent JP2023143164
Kind Code:
A
Abstract:
To provide a compartment penetration processing structure, a method for constructing a compartment penetration processing structure, and a compartment penetration processing material, capable of reducing variation in fireproof performance and improving fireproof performance.SOLUTION: A compartment penetration processing structure is a compartment penetration processing structure 10 in which a compartment penetration part 15 formed in a partition part 11 of a building and into which a long insertion body 21 is inserted has a fireproof structure, and comprises a tape-like member 4 that is arranged so as to be wrapped around the insertion body 21 one turn or more and closes at least part of an opening 13C of the compartment penetration part 15 provided in the partition part 11 and a gap 13E between an outer surface 11B of the partition part 11 and the insertion body 21. The tape-like member 4 has at least a fireproof material layer made of at least one of a fireproof putty material and a thermally-expandable expansion material. At least three layers of a base material and the fireproof material layer are laminated.SELECTED DRAWING: Figure 1
