Fire protection structure of combustible material made of long tubular body through part of the fire compartment body

摘要

(57) Abstract Objective It is penetrated completely in the complete penetration borehole of fire resisting division body such as the floor and the wall,In the complete penetration section of the ru long shaku shell, structure being simple, various sizesThe fire proof construction which is agreeable to the long shaku shell is offered. Constitution The combustible material make which penetrates completely the perforation hole B of fire resisting division body ARim of the axial direction 2 place, inside perforation hole B of long shaku shell CThermal expansible refractory material it provides 1 and 2, bends to the rim, yesTalent with the band-like, at the same time you bend to the crosswise both sides, piece 3 and 4 the possessionTo do, at the same time in the crosswise center section through-hole 5 in as needed interval of the longitudinal directionWinding the fireproof framework body 8 which it possesses, thermal expansible refractory material 1,The fireproof framework which wrapped 2, this thermal expansible refractory material wrapped 1 and 2Crosswise both ends or one end of body 8 from aforementioned fire resisting division body A outsideTo make extend on side, the opening with the aforementioned perforation hole B and fireproof framework body 8Between restoration refractory material 11 inside 10 and fireproof framework body 8.
