Title:

FIRE RETARDING PARTITION PENETRATING STRUCTURE

Document Type and Number:

Japanese Patent JP2016153569

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a fire retarding partition penetrating structure penetrated by resin piping with enhanced fire spread prevention effect.SOLUTION: A fire retarding partition penetrating structure 100 includes: a resin piping body 310 the outer periphery surface of which is entirely covered with a flame resistance fiber member 320, which is inserted into a through hole 240 formed in a partition 200 of a building structure; and a thermal expansion member 410 which encloses the flame resistance fiber member 320 inside the through hole 240. Since the outer periphery of the resin piping body 310 is entirely covered by the flame resistance fiber member 320, when a fire occurs, not the resin piping body 310 but the flame resistance fiber member 320 is first subject to influences from the heat. Thus, burning of the inner resin piping body 310 is delayed.SELECTED DRAWING: Figure 1
