〔The invention's effect〕

In the present invention, the upper main plate 1 and the lower main plate 2 are connected via the inclined main plates 3 so as to be staggered in the left-right direction, and the upper and lower sides thereof are provided with the pieces that are bent at substantially right angles thereto. , A notch 4 is formed in the corner between the upper bottom piece 1b of the upper main plate 1 and the slanted lower piece 3b of the slanted main plate 3 to form the eaves front door A, and the fastening portion is on the upper side of the folding plate. Each of the remaining pieces except the upper bottom piece 1b of the eaves-front door A is inserted and fixed to the inner surface of the eaves-point of the double roof consisting of the lower roof B having 6 and the upper roof C. Only the upper bottom piece 1b has a double roof eaves door mounting structure that abuts and is fixed to the lower surface side of the flat portion 5b on the upper surface of the folded plate of the lower roof B, so first of all, The installation workability of the front door A to the eaves can be made extremely good, secondly, the strength of the eaves of the double roof can be improved, and thirdly, The eaves with a heavy roof can have an excellent appearance, and the fourth effect is that it can be made strong against snow.

To explain these effects in detail, conventionally, in order to attach a door to the eaves of a double-roof type roof, the attachment piece formed from the door main plate of the door is used for the lower roof of the double roof. It was installed by inserting it between the roof and the roof. However, in the case where the lower roof is a roof of a treat type, the treat portion exists up to the eaves, the mounting piece cannot be inserted due to the treat portion, and only the bending piece corresponding to the place of the treat portion is inserted. , It is necessary not to form the door on the door, or some processing on the mounting piece, and the door should be attached to the eaves of the double roof, which was extremely troublesome to construct. According to, according to the inner surface of the eaves part of the double roof, insert and fix each of the remaining pieces except the lower bottom piece 2b of the eaves-side door A,
Only the lower bottom piece 2b is abutted and fixed to the lower surface side of the flat portion 5b on the upper surface of the folded plate of the lower roof B, so that the inclined main plate 3 is formed.
The sloping piece on the lower side can be arranged above the lower roof B, and the lower bottom piece 2b adjacent to the slab is separated by the notch 4, and the fastening portion 6 at the top of the folded plate of the lower roof B is formed. Not the upper side that exists,
Since it can be placed on the lower side, even if there is the fastening portion 6 on the upper side of the folded plate of the lower roof B, as shown in FIGS. 2 and 4, the fastening portion 6 should not be an obstacle. The flat portions 5b, 5b
You can cover the area. Therefore, there is the greatest advantage that the eaves-front door A can be attached very easily regardless of the presence of the fastening portion 6 of the lower roof B.

Next, the eaves-front door A is connected to the upper main plate 1 and the lower main plate 2 through inclined main plates 3 so as to be staggered in the left-right direction, and is connected to the upper and lower sides of each of them at substantially right angles to them. Since the bending pieces are provided, they are supported by entering between the upper surface of the lower roof B of the double roof and the lower surface of the upper roof C of the double roof, so that the section modulus increases and the eaves of the double roof eaves. The strength of can be increased.

Next, in the eaves of the double roof, the double roof and the eaves front door are attached by attaching the eaves front door A having a shape formed by the lower roof roof B and the upper roof roof C and having a vertical interval. A can be brought into an extremely harmonious state without any discomfort, and the appearance of the eaves can be made excellent.

Further, since the attachment of the upper roof roof C of the eaves door A that constitutes the present invention to the eaves is all inside (lower side), even in a snowy area, even when a snow mass slides to the eaves side, A firm attachment can be achieved without damaging or removing the front door A of the eaves.
