ROOF SECTION PIPING STRUCTURE OF SOLAR HEAT HOT WATER SUPPLY SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a roof section piping structure of a solar heat hot water supply system in which pipe flow passages for circulating a heat medium between a solar heat collector and a heat exchange tank are disposed easily by extending through a roof while preventing water such as rainwater from intruding to the roof rear side. SOLUTION: A nipple member 19 is inserted into through-holes 18 formed in a roof board 15 and a slate 16 which form the roof 11 in such a manner that the lower section 19a thereof projects downward from the roof board 15 and the upper section 19b projects upward from the slate 16. A lower section female screw member 21 is tightened to the lower section male screw section 20a of the nipple member 19 and the upper section female screw member 22 is tightened to the upper section male screw section 20b of the nipple member 19 in such a manner as to hold the roof 11. Then, the nipple member 19 is fixed to the roof 11. The roof rear pipe 23 is connected to the lower end of the lower section male screw section 20a, the roof upper pipe 24 is connected to the upper end of the upper section male screw section 20b, and the roof rear pipe 23 and the roof upper pipe 24 are allowed to communicate with each other through the nipple member 19.
