In the meantime, when the foamed material 500 is inflated, the space between the pipe 200 and the interlayer penetrating sleeve 100 is filled up. Even when the pipe 200 of a combustible material is melted down, By filling the space, the flame is secondarily blocked.

The granulation piping 200 is formed so that the cross section of the granulation piping 200 installed in the inner space of the interlayer penetration sleeve 100 according to the prior art is concentric with the cross section of the interlayer penetration sleeve 100, However, in the construction process, the granular pipe 200 may not be installed in the center and may have an eccentricity.

Therefore, the above-described conventional invention prevents the inner filling material of the fire resistance structure from falling due to gravity in case of fire, solves the difficulty of catching the eccentricity in the process of installing the refractory filler packed in a compressed state in the bottleneck It is necessary to provide a new type of interlaminar insulator interlocking device capable of preventing interlayer movement through the granular piping in which the flame and the smoke are melted even when the granular pipe and the mounting hole are closed on the inner wall surface of the penetrating sleeve.
