[0002]

2. Description of the Related Art Conventionally, when attaching eaves gutters to a folded plate roof, eaves gutter suspensions as described in Japanese Utility Model Laid-Open No. 57-89637 are often used.

This eaves trough suspender has a bolt whose upper end is fixed to a mountain portion of a folded plate roof with a nut, and an eaves trough attached to the lower end of the bolt so as to support the eaves trough. And a support member.

[0004]

However, in such a conventional eaves gutter suspension device, a lateral external force is applied to the eaves gutter by a side wind in a use state in which the eaves gutter is attached to the folded plate roof. When the bolt is bent, bending stress is generated around the upper end (the portion attached to the folded plate roof) of the bolt, which causes a problem that the bolt is easily bent. Further, the folded plate roof has a problem that the folded plate roof may be damaged because stress is concentrated on the portion where the bolts are fixed.

In view of the above problems, the present invention takes the above problems into consideration, and when the eaves gutter is attached to the folded plate roof, when the lateral force is applied to the eaves gutter, the bolt easily bends or the folded plate roof is bent. The purpose of the present invention is to provide a eaves gutter hanger that will not be damaged.

[0006]

In order to achieve the above object, in the eaves gutter suspension of the present invention, a eaves gutter suspension for attaching an eaves gutter to a folded plate roof having alternating peaks and valleys. There
A bolt whose upper end is fixed to the mountain portion of the folded plate roof or an intermediate portion between the mountain portion and the valley portion, and an eaves trough support member attached to the lower end of the bolt and formed into a shape capable of supporting the eaves trough. A contact plate attached to the middle portion of the bolt and having a shape capable of contacting both ends with the lower surface of the valley portion of the folded plate roof.

[0007]

[Operation] When the eaves gutter is attached to the folded plate roof, the upper end of the bolt is fixed to the mountain portion of the folded plate roof or an intermediate portion between the mountain portion and the valley portion, and both ends of the abutment plate are the valley of the folded plate roof. The eaves gutter is supported by the eaves gutter support member by contacting the lower surface of the part. Then, when a lateral external force is applied to the eaves gutter, only bending stress is generated in the bolt with the middle part (the part where the contact plate is attached) as a fulcrum, and the folded plate roof does not , The stress is generated by being dispersed in the peaks or the middle of the peaks and valleys where the bolts are fixed and the lower surface of the valleys in contact with the contact plate.

That is, the bolt is much less likely to bend as compared with the conventional case where bending stress is generated around the upper end as a fulcrum, and the folded plate roof is concentrated on the portion where the bolt is fixed as in the conventional case. Compared to the stress that occurs, it is much less likely to break.
