The snow stopper bar 6 is fixed to the bolt 13 of the protrusion 11 of the snow stopper support 3 by a fixing member 7.

  Next, a construction procedure of the waterproof structure 1 with snow stopper will be described.

  First, the positions of the rafters 104 are confirmed, and the positions at which the plurality of snow stoppers 3 are installed are determined. Then, the entire surface of the roof plate 102 is covered with the waterproof member 2, and the waterproof member 2 is attached to the surface of the roof plate 102.

  Next, the plurality of snow stoppers 3 are arranged at predetermined positions, and the respective snow stoppers 3 are fixed to the rafters 104 with fixing screws 4. After that, the first seal member 14 is attached to the base portion 10 of the snow stopper support fitting 3 and the periphery thereof, and then the second seal member 15 is attached from above the first seal member 14.

  Subsequently, the surface of the waterproof member 2 and the surface of the sealing member 5 (the surface of the second sealing material 15) are painted. Thereafter, the snow stopper bar 6 is fixed to the snow stopper support fitting 3 by the fixing member 7.

  The waterproof structure 1 with snow stopper according to the present embodiment may be installed at the same time when the roof 100 is newly installed, or may be installed on the existing roof 100.

In the waterproof structure 1 with snow stopper according to the present embodiment, the snow stopper support fitting 3 is disposed on the flat portion of the surface of the roof 100 via the waterproof member 2 and is fixed to the base of the roof 100 by fixing screws 4. . Therefore, the snow stopper support 3 can be installed on any type of roof as long as the roof has a flat portion, and the snow stopper can be installed without using the connection portion or the end of the roof plate 102. The support fitting 3 can be fixed to the roof 100. Further, the snow stopper 3 is fixed to the roof 100 by the fixing screw 4 without using the connection portion or the end of the roof panel 102, so that the entire surface of the roof 100 is covered with the waterproof member 2. Can be installed.
Furthermore, since the periphery of the base portion 10 of the snow stopper support member 3 and the base portion 10 of the waterproof member 2 are covered with the seal member 5, the roof material (the roof plate 102 and the roof plate 102) is used to fix the snow stopper support member 3. Even if a hole is formed in the base plate 103), waterproofness can be ensured.

  The preferred embodiment of the present invention has been described above, but the present invention is not limited to the above-described embodiment, and various modifications can be made as long as they are described in the claims.

  In the above embodiment, the fixing member 7 has the nut 18, the flat washer 19, and the spring washer 20, but components other than the nut 18 may be different.

In the above-described embodiment, the bolt 13 of the protrusion 11 is inserted into the through hole 16 a formed in the snow stopper bar 6 and fastened by the fixing member 7, so that the snow stopper bar 6 projects from the snow stopper support 3. Although fixed to the portion 11, the structure for fixing the snow stopper bar 6 to the protruding portion 11 of the snow stopper support 3 is not limited to the above.
For example, instead of providing the bolt portion 13, a plate-shaped portion that is parallel to the base portion 10 and has a larger area than the columnar portion 12 is provided, and the plate-shaped portion and the mounting plate portion 16 of the snow stopper 6 are overlapped. Both ends may be fixed by a fixing member.

  In the above embodiment, the fixing screw 4 penetrates the rafter 104 which is a C-shaped steel. However, as shown in FIG. 4, the fixing screw 204 does not have to penetrate the rafter 104. The fixing screw 204 is a self-drilling screw, and is shorter than the fixing screw 4 in the above embodiment. The fixing screw 204 can penetrate the upper part (the part in contact with the roofing material) 104a of the rafter 104 without making a pilot hole. By screwing the fixing screw 204 into the upper part 104 a of the rafter 104, a screw thread is formed in the upper part 104 a of the rafter 104, so that the fixing screw 204 can be screwed and fixed to the rafter 104. According to this configuration, since the fixing screw 204 does not need to be screwed into the lower part of the rafter 104, workability is improved. Further, since the fixing screw is shorter than in the above embodiment, the material cost of the fixing screw can be reduced. Note that the rafter 104 in FIGS. 2 and 4 is a C-shaped steel. When the rafter 104 is a steel material other than the C-shaped steel, the fixing screw may penetrate only the upper portion of the rafter 104 as in FIG. 4 or may penetrate the entire rafter 104 as in the above embodiment. When the rafter 104 is made of wood, the fixing screw may or may not penetrate the rafter 104.
