2. Description of the Related Art Eaves gutter is, for example, Jitsuko Sho 61-3376.
Eaves gutter hangers as described in Japanese Patent No. 7 and Shokai 5
It is attached to the eaves of the building by an eaves gutter support as described in Japanese Patent Publication No. 8-86831.

However, when a load is applied to the eaves gutter by hanging a ladder or hitting a ball, the eaves gutter's cross-sectional shape is deformed, and the eaves gutter hangs or eaves gutter supports (hereinafter , Collectively referred to as eaves gutter fittings), causing water leakage. Further, there is a problem that the eaves gutter meanders due to its own thermal expansion and contraction because the expansion and contraction processing function provided in the joint portion and the like cannot be sufficiently exerted, and it becomes unsightly.

As a means for solving this problem,
It is easy to narrow the pitch of the eaves trough fixtures, but if you do so, it will be necessary to fix more eaves trough fixtures to the building than before, which will reduce workability at the construction site. .

Another means is disclosed in Japanese Patent Laid-Open No. 61-61
It is conceivable to attach a reinforcing tool to the eaves trough at a position between the eaves trough fittings and the eaves trough fittings as described in Japanese Patent Laid-Open No. 106856. This reinforcement tool is used by straddling it between the front and rear side walls of the eaves gutter, and bending pieces that can be fitted into the fitting recesses formed on the inner surface of the side wall of the eaves gutter are provided at both ends. Has been.

[0006]

However, in such a conventional eaves trough reinforcing device, by attaching it to the eaves trough, the rigidity in the cross-sectional direction and the axial direction of the eaves gutter can be increased. As a result, the eaves gutter can be prevented from being deformed and meandering without narrowing the pitch of the eaves fitting, but the eaves with fitting recesses formed on the inner surface of the front wall and the inner surface of the rear wall, respectively. Since it can be attached only to the gutter, there is a problem that it cannot be used together with the existing eaves gutter.

In view of the above problems, the present invention can be attached to an existing eaves trough and prevents the eaves trough from being deformed or meandering without narrowing the pitch of the eaves trough fixture. The object is to provide a reinforcement tool for eaves gutter that can be used.

[0008]

In order to achieve the above object, the eaves trough reinforcement of the present invention is provided with a front ear fitting portion which can be fitted to the front ear of the eaves trough at one end. A rear ear fitting part capable of fitting to the rear ear of the eaves gutter is provided at the other end, and is formed by a rod between the front ear fitting part and the rear ear fitting part. A bridge portion is provided between the front and rear side walls, and the bridge portion contacts the inner surface of the front wall of the eaves gutter and the rear contact portion of the rear wall of the eaves gutter. It is configured to have a shape having a contact portion.

[0009]

According to the eaves trough reinforcement of the present invention, the front ear fitting portion is fitted to the front ear of the eaves trough, and the rear ear fitting portion is fitted to the rear ear of the eaves trough. Can be installed.
In the eaves trough reinforcing device thus attached to the eaves trough, the bridge spanning between the front and rear side walls of the eaves trough is located between the front and rear side walls of the eaves trough. To prevent the gap between the front and rear side walls of the eaves gutter from being narrowed, and the front and rear ear fittings should be able to position the front and rear ears of the eaves trough. The retention prevents the spacing between the front and rear side walls of the eaves gutter from expanding. That is, it is possible to prevent the cross-sectional shape of the eaves gutter from being deformed, and also to prevent the eaves gutter from meandering.
