By intentionally fastening the first screw slightly downward, the pull-out resistance can be effectively exhibited in use even if the first screw is not exactly orthogonal to the surface of the skeleton 14. It can be regarded as substantially orthogonal.
Further, other than orthogonal to the surface of the skeleton 14, it means that the mounting angle of the second screw is a difference angle that cannot be regarded as orthogonal so that the shear strength can be effectively exhibited in use. In particular, the mounting angle of the second screw is considerably different from the mounting angle of the first screw (orthogonal to the skeleton surface and the angle from the horizontal plane is almost 0 degrees), for example, 10 from the surface of the skeleton 14. It is in the range of degrees to 45 degrees, preferably about 45 degrees.

Therefore, by combining the pull-out strength of the coach screw 15 and the shear strength of the course thread 16, the pull-out strength of the case 2 attached to the skeleton 14 via the rear peripheral wall portion 25C of the bracket 22 is improved. To do.

The rear peripheral wall portion 25C of 22 is fixed to the skeleton 14, and at this time, the course thread 16 is driven diagonally with respect to the surface of the skeleton 14, so that the shearing force of the course thread 16 is applied to the skeleton case 2. Since the force of pulling out vertically from 14 is resisted, the pull-out resistance of the case 2 attached to the skeleton 14 can be improved.

Further, an inclined flat plate portion 62 is formed on the rear peripheral wall portion 25C of the bracket 22 which functions as an attachment portion to the skeleton 14 so as to extend in a direction other than orthogonal to the surface of the skeleton 14, and the inclined flat plate portion 62 is formed. Since the second through hole 61 for penetrating the course thread 16 is formed so as to penetrate the portion 62, the second through hole 61 formed in the inclined flat plate portion 62 with respect to the surface of the skeleton 14. Since it functions as a guide hole when fastening the course thread 16 to the skeleton 14 so as to be in a non-orthogonal crossing state, when fastening the course thread 16 so as to be in a non-orthogonal crossing state with respect to the surface of the skeleton 14. Workability is improved.

Further, conventionally, in order to improve the pull-out resistance of the case, it is necessary to form a hole for a through bolt in the skeleton to allow the bolt to penetrate, and to improve the sitting of the bolt head with respect to the skeleton. Counterbore processing is required for the skeleton, and when performing counterbore processing, work from both one surface side (for example, indoor side) and the other surface side (for example, outdoor side) of the skeleton is required. However, there is a problem in terms of workability, but according to the method of attaching the case 2 to the skeleton 14 according to the embodiment, it is complicated to form a hole for a through bolt in the skeleton 14 to allow the bolt to penetrate. Case 2 in which the pull-out resistance of Case 2 can be sufficiently secured by simply fastening the coach screw 15 and the course thread 16 from one surface side (for example, the indoor side) of the skeleton 14 without performing any work. It becomes possible to realize the mounting structure of.

That is, according to the method of attaching the case 2 to the skeleton 14 according to the embodiment, the workability of attaching the case 2 to the skeleton 14 can be improved, and the pull-out resistance of the case 2 can be improved. That is, according to the embodiment, it is possible to provide a mounting method for the case 2 that can secure the mounting strength and improve the workability when the case 2 is mounted on the skeleton 14.
