FIRE PROTECTION DIVISION PENETRATING PART CONSTRUCTING METHDO FOR HEAT RESERVING PIPING

摘要

PURPOSE: To provide a constructing method for securing a reliable fire-resisting construction, good workability, and possibility to make construction only from an upper stage, in a fire protection division prenetrating part construction method. ;CONSTITUTION: A heat reserving piping 3 from which a heat reserving material 4 is partially separated is inserted into a frame 2 which is inserted into the penetration hole 1 of a floor surface 7 to approximately the thickness of an floor, and two-divided partition plates 6 are inserted into the bottom part of the frame 2, and a putty-like fireproof seal member 8 is filled into the heat reserving material part separated from the upper surface of this partition plate 6, and heat insulating material 9 is filled thereon, and a protective tape 11 is wound around the outer surface of the heat reserving piping 3 just above the part from which the heat reserving material 4 is separated, moreover foaming heat insulating material 10 is poured into the upper end of the frame 2 on the heat insulating material 9, so as to produce foaming.;COPYRIGHT: (C)1995,JPO
