FIREPROOFING DEVICE AND BUILDING FIREPROOF STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide: a fireproofing device capable of avoiding falling off a through hole of a partition even when a vibration or impact is applied thereon from an outside, and a building fireproof structure using the fireproofing device.SOLUTION: A fireproofing device 1 is disposed in a through hole 12 formed in a partition 11 of a building and having at least one tubular body 13 inserted therein, and is used for fireproofing of the through hole 12. The fireproofing device 1 comprises: a cylindrical body part 2 which has a thermal expansion property and is inserted in the through hole 12 and in which the at least one tubular body 13 is inserted; a first locking part 3 exposed from the through hole 12 and hooked on one outer surface of the partition 11; and a second locking part 4 exposed from the through hole 12 and hooked on the other outer surface of the partition 11.SELECTED DRAWING: Figure 1
