The mounting plate portion 5 is mounted on a roof base material 33 such as a rafter or a purlin on the back side of the roof plate 30 above the roof plate 30 with a stopper 34. And the lower roof plate 30
The snow stopper 1 disposed on the roof in a direction intersecting with the roof flow direction is inserted and fixed in a space between the holding portion 10 and the partition 45. As a result, a gap is formed between the snow stopper 1 and the surface of the lower shingle 30 so that snowmelt and rainwater do not accumulate.

[0003]

However, the snow on the roof melts to form water, and the water accumulated on the snow accumulates inside the support fitting 2, and the accumulated water flows from the joint of the shingle 30 to the attic or the like. There is a problem of leaking into a room, that is, so-called leakage. In heavy snow areas, this type of support 2 must be at least 4
Requires a proof stress of 00 kg or more. For this reason, the thickness of the support bracket 2 is increased to increase the strength (approximately 4.5 mm).
Thickness), when the thickness is increased, the bending process is not easy, and in particular, both the roof plates are increased by the thickness of the mounting plate portion 5 passed between the lower roof plate 30 and the upper roof plate 30. 30 ・
A large gap is formed between the 30 polymerized surfaces, which is not preferable in the rain treatment. The lower shingle 30 and the upper shingle 30
It is necessary to bend the step 46 in the middle of the mounting plate 5 in order to absorb the step difference from the above, but this bending is not easy. In addition, since the weight is large, there are also problems such as construction, transportation costs, and burden on the roof shingles.

[0004] Further, in the support bracket 2 of the conventional example described above,
After the partitioning plate 45 is fitted inside the holding part 10, the two parts are integrally joined by welding. However, the welding causes heat distortion and makes it difficult to pass through the snow stopper 1, so that the shape is corrected after welding. It is necessary to add rust prevention treatment to the welded portion. The holding part 10 is formed in the shape of a right triangle by the bottom plate part 6, the vertical plate part 9, and the inclined plate part 7, and the vertical plate part 9 is attached to the eaves direction and the inclined plate part 7 is attached to the ridge direction. Have been. However, when the snow stopper 1 is fixed to the vertical plate 9 of the support 2 with a stopper 43 such as a bolt to prevent the snow stopper 1 from coming off, the vertical plate 9 is completely visible and the stopper 4
The head of No. 3 is seen from the eaves side and impairs the appearance of the roof.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the problem of leakage and welding in a device for mounting a snow stopper made of an angle bar on a roof in a direction intersecting with the roof flow direction by using a support bracket. . Another object of the present invention is to secure the strength while reducing the thickness of the support bracket, to simplify the bending process and the rain finishing process, and to simplify the construction and transportation by reducing the weight. . Still another object of the present invention is to improve the design effect on the roof.
