<p>PURPOSE:To improve workability by disposing a heat insulation coating copper pipe and accompanying control cable into a through-part, disposing an expandable fireproof plate on the outer periphery of the heat insulation coating and the control cable and packing a curable refractory packing material into the through-port so as to cover the spacing thereof. CONSTITUTION:The copper pipe 1 clad with the heat insulation coating 2, such as foamed polystyrene or urethane, and the accompanying control cable 3 are inserted and disposed into the through-port 8 formed on a floor 7. The heat insulation coated copper pipe 1 and the accompanying control cable 3 are inserted into the open part on one side of a supporting fitting-4 made of a copper wire in the on-the-floor part of this heat insulation coated copper pipe 1 and the accompanying control cable 3. The supporting fitting 4 made of the copper wire is inserted into the through-port 8 and the upper side of the supporting fitting 4 made of the copper wire 4 is hooked to the upper part of the floor. An inorg. fiber board 6 is then disposed in the spacing part of the supporting fitting 4 made of the copper wire and the expandable fireproof plate 5 is disposed and fixed to cover the outer periphery of the heat insulation coating 2 and the accompanying control cable 3. The curable refractory packing material 9 is packed into the through-port so as to cover the spacing thereof. The workability is improved in this way.</p> |
