For example, at the ceiling level downstairs, a barrel 1 having a U-shaped cross section with an open front is installed.
A stiffener (stiffener) 2 in the shape of a vertical plate is welded to an appropriate position of the body 1 to increase the strength of the barrel 1. By using such a stiffener 2, an attached structure 4 such as an entrance eave or a large eave is attached via a fitting 3. The mounting hardware 3 is attached to the stiffener 2 with one bolt 9 while preventing rotation, thereby improving workability. Hereinafter, such a configuration will be described in detail. In the embodiment, the attached structure 4 is a unitized entrance eave 4A.

FIG. 5 shows a mounting hardware 3 which is attached to a front plate 5 on which an attached structure 4 is mounted, and to a stiffener side surface 6 of the stiffener 2 in a direction orthogonal to the length direction of the trunk 1. It has a mounting plate 7 to be mounted in contact with. The mounting plate 7 is formed with two mounting holes 12 and 12 vertically, but the upper mounting hole 12 is used, and the other mounting holes 12 are used when turned upside down. I do. At the rear end of the mounting plate 7, a detent piece 8 is extended in the length direction of the barrel 1, abuts against the front surface 1 a of the barrel 1, and stops the mounting hardware 3 from rotating.

Then, the mounting plate 7 of the mounting hardware 3 is brought into contact with the stiffener side surface 6 and mounted with one bolt 9, and the detent piece 8 is brought into contact with the front surface 1 a of the trunk 1 to stop the detent. It is a plan. In this case, the horizontal pieces 13, 13 extend rearward from the upper and lower ends of the front plate 5, and a slit 14 is formed in the horizontal piece 13, and the slit 14 is engaged with the stiffener 2. Further, the front plate 5 is positioned forward of the front edge of the trunk 1 to position the exterior plate 15. Exterior plate 1
5 is fixed to the base material by tapping screws 16. The entrance eaves 4A unitized as the attached structure 4 and formed in a box shape is arranged outside the exterior plate 15 and is provided with the exterior plate 15
At the same time, the locking frame of the entrance eaves 4A is locked and supported by the eave box support plate 17 fixed to the base side. Further, the attachment frame 18 formed on the upper edge of the entrance eaves 4A is attached to the attachment hardware 3 by the tapping screw 19.

As described above, the mounting plate 7 of the mounting hardware 3 is brought into contact with the stiffener side surface 6 and is mounted with one bolt 9, and the detent piece 8 is brought into contact with the front surface 1 a of the bobbin 1. Since the rotation of 3 is prevented, the mounting hardware 3 can be mounted with one bolt 9, thereby improving workability and avoiding interference with screws for attaching the attached structure 4.

By the way, the inclined piece 11 which escapes the weld overlay 10 in which the stiffener 2 is welded to the body insert 1 is attached to the mounting plate 7.
Is formed between the stiffener 2 and the rotation stopper piece 8.
Can be escaped by the inclined piece 11 without impairing the function of the rotation preventing piece 8.

FIGS. 6 to 8 show another embodiment. However, the basic structure of this embodiment is the same as that of the above-described embodiment. Omitted.

In this embodiment, the mounting hardware 3 is
A front plate 5 for attaching the attached structure 4 and a mounting plate 7 attached to the stiffener 2 so as to abut on a stiffener side surface 6 of the stiffener 2 in a direction orthogonal to the length direction of the trunk 1 are provided. Folded pieces 20, 20 that are folded back in a direction orthogonal to the face plate 5 are formed.

Thus, the mounting plate 7 is connected to the stiffener side surface 6.
The upper and lower folded pieces 20, 20 of the front plate 5 are in contact with the front edge 2a of the front end of the stiffener 2 with a vertical interval.

In this case, as shown in FIG. 7 (b), the upper and lower folded pieces 20, 20 may be brought into contact with one stiffener 2, but as shown by a part (a) in FIG. The two stiffeners 2 may be brought into contact with each other.
Further, in the present embodiment, the folded piece 20 may not be provided.

Thus, the front plate 5 of the mounting hardware 3 is brought into contact with the front end vertical edge 2a of the stiffener 2.
Therefore, the mounting hardware 3 may be attached with a single bolt 9, thereby improving workability and avoiding interference with screws for attaching the attached structure 4.

In this case, as shown by a part a in FIG. 7A, two stiffeners 20 and 20 are provided at the upper and lower ends of the front plate 5 so as to be folded back in the direction perpendicular to the front plate 5. The contact between two and two can enhance the stability of the front plate 5.

Extend the detent piece that comes out and comes into contact with the front of the barrel to prevent rotation of the mounting hardware. Then, attach the mounting plate to the side of the stiffener, attach it with one bolt, and attach the detent piece to the Since the attached structure is attached to the front plate of the mounting hardware by contacting the front surface, the rotation of the mounting hardware can be prevented by abutting the detent piece on the front of the girth, so one mounting hardware is required. It is advantageous in that the workability can be enhanced and interference with the screws for attaching the attached structure can be avoided.

According to the second aspect of the present invention, in addition to the effect of the first aspect, an inclined piece which escapes the weld overlay where the stiffener is welded to the girth is formed between the mounting plate and the detent piece. Therefore, there is an advantage that the weld overlay when the stiffener is welded to the girth can be escaped by the inclined piece, and the function of the detent of the detent piece is not impaired.

According to the third aspect of the present invention, there is provided a structure in which an attachment is attached to a stiffener attached to the girth, and an attached structure is attached via the attachment. A mounting plate attached to the stiffener in a direction perpendicular to the lengthwise direction of the body insert, the mounting plate being in contact with the stiffener side, the mounting plate being abutted to the stiffener side, and being mounted with one bolt to secure the front plate to the stiffener. Because the attached structure is attached to the front panel and the front panel is attached to the front edge of the front panel, the mounting panel can be prevented from turning by contacting the front panel with the front of the body, so that the mounting bracket can be attached to one It may be attached by bolts, and there is an advantage that workability can be improved and interference with screws for attaching an attached structure can be avoided.
