Fire proof construction of fire resisting division body complete penetration section of long shaku body

摘要

(57) Abstract Objective Fireproof performance improve. Space efficiency directionPromote. It can apply simply from one side of the fire resisting division bodyThe sea urchin do. Decrease application man-hour. Perforation hole 2 smallMake diameter conversion possible. Constitution As a sleeve component 4, thermal expansible refractory material 5Making provision the cylinder part 7 which it stores for the both ends, these cylinder parts between 7 and 7 suThe concatenated section where the window 9 where leave it communicates inside and outside component 4 was formedThose which possess 8 were used. And this sleeve component 4Way that window 9 is located inside perforation hole 2, the fire resisting division bodyTo lock in 1, through the window 9, from inside sleeve component 4To the inner wall surface of the perforation hole 2 it put in communication state.
