Set up Further, a through hole 27 for the mounting bolt 22 is bored in the middle part of the board 23, and an engaging claw 27 is formed in the upper end of the vertical wall 24.
8 is provided protrudingly, and a recess 29 is carved on the outer surface of the lower part of the inclined wall 25.

Subsequently, the base piece 31 of the drain cover 30 made of an aluminum alloy extruded shape extending back and forth and the supporting piece 32 protruding from the lower surface of the base piece 31 are placed on the vertical wall 24 and the supporting wall 26 of the bracket 18. Then, the protrusion 34 at the lower end of the engagement piece 33 hanging down inside the base piece 31 is engaged with the engagement claw 28 of the vertical wall 24, and the hanging piece 3 hanging down outside the base piece 31 is engaged with the engagement claw 28 of the vertical wall 24.
The engaging protrusion 36 at the lower end of the frame 10 is engaged with the recess 29 of the inclined wall 25, and the base piece 31 is made oblique with the inner side higher than the outer side and placed on the bracket 18 so as to be substantially parallel to the upper surface of the frame 10. Further, the draining cover 30 has a rising piece 37 projecting upward toward the inner side, and a watertight gasket 39 is fitted into a support groove 38 at the upper end of the rising piece 37.

A cover plate 40 made of an extruded aluminum alloy and having a U-shaped cross section and extending back and forth is set to a size that covers the gap between the frames 10, is placed on the gasket 39, and is placed on the rising piece 3 of the drain cover 30.
The ends of the W-shaped spring clip 42 are engaged with both horizontal engaging pieces 41 having protrusions at the upper ends of the spring clip 42, and the bolt 43 inserted from the outdoor side of the cover plate 40 to the indoor side is inserted into the center of the spring clip 42. It is fixed by screwing onto a roller nut 44 attached to the lower surface.

Reference numerals 45 and 46 are caulking, 47 is a waterproof sheet, and 48 is a rooftop floor tile.

In FIGS. 3 and 4, it is made of a synthetic resin such as vinyl chloride and extends back and forth, and an engagement frame 49 is bulged on the lower surface of both ends thereof, and a plurality of tongue pieces 50 are provided on the lower surface inside the engagement frame 49. The protruding water stop plate 51 is attached to a holding groove 52 of a water stop plate edge material 54 made of an extruded aluminum alloy profile that extends back and forth and includes a U-shaped holding groove 52 and a connecting piece 53 protruding from the base piece of the holding groove 52.
