[0026]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Specific embodiments of the present invention will be described with reference to the drawings.

The present embodiment is provided at a site where a snow corn occurs due to snowfall, such as the upper edge 2 of the building 1, and has a lattice-shaped snow corn prevention member 3 and a support member 4 for supporting the snow corn prevention member 3 in an upright state. A snow eaves prevention device comprising:
A mounting body 6 to be mounted on the roof (mounting site 5) of the building 1
And a support portion 7 for supporting the snow eaves preventive member 3 above the mounting body 6. The mounting body 6 has a plurality of divided mounting bodies 8 arranged side by side and slides vertically. It is configured to be connected so as to be movable and adjustable.

The supports 4 are arranged side by side at predetermined intervals along the upper edge 2 of the building 1, and the snow eaves preventer 3 is attached to the upper edge 2 of the building 1 by the juxtaposed supports 4. It is configured to be extended along.

It is preferable that the divided mounting member 8 be made of a heavy and corrosion-resistant material such as a concrete block.

The split mounting body 8 is long in the up-down direction,
In the horizontal direction, the width in the juxtaposition direction is narrow, and the length in the direction orthogonal to the juxtaposition direction is long. Therefore, the divided mounting bodies 8 easily fall over in the juxtaposition direction, but hardly fall down in the direction orthogonal to the juxtaposition direction. Further, when the placing body 6 is placed on the inclined placing portion 5 by the narrow width of the juxtaposing direction, the lower surface of the placing body 6 can be brought closer to the inclined state of the placing portion 5 described above, The mounting body 6 can be mounted in a stable state. In addition, the divided mounting body 8 becomes heavier by the length in the horizontal direction and the direction orthogonal to the juxtaposition direction, and as a result, the mounting body 6
The whole becomes heavy, and the mounting body 6 can be mounted in a stable state.

The direction in which the divided mounting bodies 8 are juxtaposed is set in the direction in which the snow eaves preventive body 3 extends. Therefore, the snow eaves prevention body 3
Even when the mounting portion 5 is inclined in the extending direction of the mounting member, the plurality of divided mounting members 8 are slid in the vertical direction by their own weight or by pushing, whereby the lower surface of the mounting member 6 is tilted. The supporting portion 7 provided on the mounting body 6 in a predetermined state,
For example, it can be in a vertical state.

When the mounting body 6 is tilted in the same manner as the mounting part 5, the supporting portion 7 provided on the mounting body 6 does not assume a predetermined state, for example, a vertical state, and the mounting part 6 is not in a vertical state. There is a risk that the load may not be able to withstand the pushing load or that the mounting body 6 may fall due to the pushing load of the snow (that is, the whole snow eaves prevention device may fall).

Although the mounting body 6 in the drawing shows a configuration in which three divided mounting bodies 8 are arranged in parallel, it is sufficient that the number of the divided mounting bodies 8 is two or more. Further, if three or more divided mounting bodies 8 are arranged side by side, and the supporting parts 7 are attached to the divided mounting bodies 8 in the center, the divided mounting bodies 8a to which the supporting parts 7 are attached are divided and mounted on both sides. Each of the placement bodies 8 is present, and the divided placement body 8a provided with the support portion 7 is in a stable state.

The connecting structure will be described in detail. A connecting hole 9 is provided in each of the divided mounting members 8, and the connecting rod 10 is inserted into the connecting hole 9 in a vertically loosely fitted state. When the divided mounting body 8 is placed on the mounting portion 5 inclined in the direction in which the mounting bodies 8 are juxtaposed, the divided mounting body 8 slides vertically with respect to the connecting rod 10 by its own weight or by pushing. The lower surface of the placing body 6 is configured to correspond to the inclined state of the inclined placing portion 5.

Also, with this configuration, the connecting rod 10 is locked to the divided mounting body 8, so that the vertical movement of the divided mounting body 8 can be prevented.

Further, retaining portions 11 and 12 are provided at the distal end portion and the proximal end portion of the connecting rod 10, so that the divided mounting body 8 is prevented from falling off.

The retaining portions 11 and 12 employ a threaded body that is screwed to the connecting rod 10, or one of the retaining portions 11 employs a threaded body such as a nut and the other. If a bolt head is used as the retaining portion 12, the retaining portion 11
It is possible to make the space wider and narrower, and the separated mounting bodies 8 in the juxtaposed state are sandwiched between the retaining portions 11 and 12, and the divided mounting bodies 8
Can be disabled in the vertical direction. In other words, in this embodiment, the vertical movement of the divided mounting body 8 can be prevented by the holding of the divided mounting body 8 between the retaining portions 11 and 12.

In this embodiment, a long hole having a vertically long cross section is used as the connecting hole 9. Therefore, the divided mounting body 8 can slide satisfactorily in the vertical direction with respect to the connecting rod 10 inserted in the connecting hole 9 in a loosely fitted state. It becomes difficult (or impossible) to slide in the direction. Therefore,
According to this configuration, the split mounting body 8 can be slid and adjusted only in the vertical direction.
