In general, it is very important to close the interlayer penetration part in high-rise building construction as a measure to localize or minimize the damage by preventing toxic gas and flame from spreading rapidly to the adjacent room when a fire occurs in an actual building. To prevent the fire from being diffused more and more, it is divided into 'interlayer fire protection compartment', and the work of sealing the gap by using the filler (filler) of heat-resistant and refractory material separately .

The PVC granular pipe occupying most of the granular pipes passing through the through sleeves 102, which are the interlayer penetrations of the slab concrete 160, is burnt when a fire occurs. Therefore, as shown in FIGS. 1 and 2, And the foamed refractory filler 130 is installed on the outer surface so as to be enclosed in the penetrating sleeve 102.

When the PVC granular pipe 120 is fired when a fire occurs, the fire-resistant filler 130 installed therein is foamed and expanded to fill the outside and inside of the PVC granular pipe 120, thereby sealing the penetrating sleeve 102, which is a fire partition .

However, in the case of a high-rise building, since the through-hole is designed to be large in order to secure an error range when it is connected to the upper and lower layers through the granular piping, the clearance of the through-sleeve 102 is so wide that the flameproof sealant or fire- It is required that the worker should considerably inconveniently work with the sealant, and the productivity of the equipment is deteriorated due to an increase in facility cost due to excessive use of the refractory filler material, which is a very expensive additive material.

Also, the pipe support 180 is used to induce the uprighting of the PVC granular pipe 120 when the refractory filler 130 is installed in the conventional PVC granular pipe 120.

The frame 110 as shown in FIG. 1 is used as fixing means for fixing the refractory filler 130 so as to surround the outer surface of the conventional PVC granulated pipe 120. Such a frame 110 may be a refractory It is possible to fill the gap between the PVC granulating pipe 120 and the through sleeve 102 when using the wide gap between the through sleeves 102 and to secure the filling space 130 between the inner side space of the PVC granulating pipe 120 If the designer is designed to seal only the inside of the PVC granular pipe 120 in the drawing, the amount of the actual installed fire-retardant filler 130 is not limited to the PVC granular pipe 120 and the through-hole sleeve 102 can not be completely filled with the inside of the PVC granulation pipe 120 and the inside of the fire partition can not be sealed.
