PROBLEM TO BE SOLVED: To improve earthquake resistant performance and to facilitate execution by clamping one end of an earthquake resistant coupler at an earthquake resistant reinforcing fitment via a bolt, and fixing the other end of the coupler to a support. SOLUTION: An earthquake resistant reinforcing fitment 4 is superposed on an upper surface of a hot water supply tube reinforcing fitment 3 in the state that a hot water supply tube 2 is inserted into an insertion hole of the fitment 4, engaged with a nut 3d mounted at a bottom of a bolt hole 3C, and the fitment 3 is connected to the fitment 4. A bolt 4c penetrating a bolt hole of a top plate 6 is inserted from a lower surface of the fitment 4, and a nut 14 is clamped at the bolt 4c on the plate 6. Thus, the plate 6 is fastened to the fitment 4. The bolt 4c is passed through a bolt hole of an earthquake resistant coupler 11, and a nut 15 is clamped to mount one end of the coupler 11. And, the other end of the coupler 11 is mounted at a wall fixing fitment 17 fixed to a support 20 (wall). |
