<p><P>PROBLEM TO BE SOLVED: To raise a waterproof effect of rainwater, etc. in a support metal fitting on a roof for supporting various articles on the roof. <P>SOLUTION: A waterproof support metal fitting on a roof consists of: a base part 11 formed so as to stretch over a projection thread part in the flow direction of the roof; a standing part 15 which extends upward from the base part 11; and a support part 18 provided at the upper end of the standing part 15. The base part 11 consists of: an upper end plane part 12; both side surface parts 13 on both sides of the upper plane part 12; and joint surface parts 14 on the lower ends of both side surface parts 13. The waterproof support metal fitting is screwed and fixed to the roof by a fixing screw 19 approximately at the center portion of the base part 11, first waterproof members 2 are arranged on the lower surface of the upper end plane part 12 of the base part 11, and the upper surface of the roof located between both side surface parts 13, and a second waterproof member 4b is arranged between the first waterproof members 2. A second waterproof member 4 is interposed between the joint surface part 14 of the base part 11 and the roof. As the first waterproof member 2 (butyl rubber), a material with relatively lower viscosity than that of the second waterproof member 4 (ethylene propylene rubber) is used. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
