It is fixed using wood screws 13 screwed into it. At that time, the front side of the lower horizontal portion 3 is disposed slightly beyond the edge h of the roof portion H, and the drooping portion 6 extends downward from the upper surface of the roof portion. One base member 2 is formed in a length of several meters, for example, 3 meters in the direction perpendicular to the paper surface of the drawing, and a plurality of them are continuously arranged.

  As shown in FIG. 3, the joint bracket 15 has a shape in which a rough numeral “7” is turned upside down, and the joint horizontal portion 17 positioned above the upper horizontal portion 7 of the base member 2 when assembled. And a front drooping portion 19 and a rear drooping portion 21 hanging downward from both ends thereof. The front end portion of the horizontal portion 17 is a raised portion 17a that rises upward, and a substantially circular cutout 25 is formed from the lower surface side. A downward projection 23 is formed on the lower surface side of the horizontal portion 17 at a position slightly ahead of the center in the front-rear direction.

  The front drooping portion 19 includes, in order from the top, a first straight portion 19a that hangs straight down, a first inclined portion 19b that is slanted downward and rearward, a second straight portion 19c that hangs straight down, and a first straight portion 19c that leans downward and forward. 2 It becomes the inclined part 19d. A hook 27 extending rearward from the inner surface side is formed at a position where the second drooping portion 19c and the second inclined portion 19d are connected, and two inner surfaces of the second straight portion 19c are vertically separated from each other. Protrusions 29a and 29b having a substantially semicircular cross section are formed. Further, a substantially circular notch 31 is formed on the inner surface near the lower end of the second inclined portion 19d. On the other hand, the rear drooping portion 21 is much shorter than the front drooping portion 19, and a hook 33 extending forward from the inner surface side is formed substantially at the center in the vertical direction. The length of one joint bracket 15 in the direction perpendicular to the drawing sheet is much shorter than that of the base member 2, for example, 30 cm, and is adjacent to the base member 2 at an appropriate interval and adjacent to the base member 2. It is arranged at the part where 2 is connected.

  Referring to FIG. 4, the cover body 35 also has a shape such that the numeral “7” is turned upside down, and the cover horizontal portion 37 extending in the front-rear direction and the first and second hanging portions depending downward from both ends thereof. 39, 41. The cover horizontal portion 37 includes a front horizontal portion 37a and a rear horizontal portion 37b connected via a shoulder portion 37c, and the first horizontal portion does not interfere with the raised portion 17a of the joint bracket 15 when assembled.

There is no rattling between the members.

  After this assembly is performed, the waterproof layer 51 is laid on the roof using an adhesive or the like as appropriate, and its end is raised along the rising portion 5 of the base member 2 at a substantially right angle. Caulking 53 is applied between the upper horizontal portion 7 of the member 2. In this way, the end of the waterproof layer 51 rises substantially vertically unlike the conventional example and does not become a slope, so there is very little possibility that rainwater will enter the mounting material 1 and the rain finish is good. Further, when the joint bracket 15 is attached to the base member, the joint bracket 15 is attached at an appropriate interval on the cover member, and is disposed at a position corresponding to the joint of the adjacent cover bodies 35, that is, the joint of the base member 2. Even if rainwater enters from the joint, the rainwater is received and discharged by the joint bracket 15 and does not flow into the coking 53 or the like through the joint of the base member 2.

  FIG. 5 is a cross-sectional view showing the waterproof layer end attachment 61 used at the corner of the roof, that is, the R portion, but the basic structure is the same as that of the waterproof layer attachment 1 used for the straight portion described above. Therefore, only different parts will be described.

  The base member 62 includes a base body 63 and a floor plate 67 attached below the base body 63. The base main body 63 is different from the base member 2 described above in that the lower horizontal portion 64 is shorter than the lower horizontal portion 3 of the previous base member 2 and is higher than the rising portion 65 by the thickness of the floor plate 67. It is provided in a position, and its hanging portion 66 is long. Accordingly, the height position of the upper horizontal portion 63a is the same as that of the upper horizontal portion 7 of the base member 2 arranged at the straight portion, and the joint bracket is connected to the joint between the base member arranged at the straight portion and the cover body. There is no hindrance to installation. The floor plate 67 has a long and narrow plate shape, and is longer than the lower horizontal portion 64, and its front end is abutted against the inner surface of the hanging portion 66 of the base body 63 with respect to the base body 63 bent into an arc shape. In this state, a plurality of them are arranged radially at appropriate intervals and fixed to the base body 63 by brazing. The floor plate 67 is fixed to the roof portion H.

  The joint bracket 15 is the same as that used for the previous straight portion. The cover body 71 is formed by brazing two members, a cover body 72 and a rear member 73, which are obtained by dividing the cover body 35 into two at the position of the upper end of the shoulder portion 37c of the cover horizontal portion 37 as shown in the figure. It is composed. The cross-sectional shape of the cover body 71 is substantially the same as the shape of the cover body 35 described above, but there is no portion corresponding to the hook 47 and the protrusion 49 formed on the second hanging portion 41. In this example, as shown in the figure, the members are hooked together, and the cover body 71, the joint bracket 15 and the base member 62 are coupled using a screw 75 with a water stop washer 76. As a result, the three members are more firmly coupled, and rattling is more reliably prevented.
