BACKGROUND OF THE INVENTION
The present invention relates to a snowfall / soil leakage prevention device and its mounting bracket on an inclined roof, and more particularly to a snowfall / soil leakage prevention device suitable for an inclined roof having a gradual slope of a folded plate type.
[0002]
[Prior art]
In general, in a snowy region, in order to accumulate snow once in the valley so that natural snow melting is possible, an inclined roof having a deep valley (high mountain) and a gentle slope is employed. Snow eaves (snowpi) are likely to occur in the eaves valley part of such an inclined roof, and there are dangers such as destruction of articles due to snowfall and damage to passers-by under the eaves. In addition, when the snow accumulated on the eaves and the like repeatedly melts and freezes to form an ice bank, the snow accumulated on the roof melts due to the rise in daytime temperature and the indoor temperature, and water accumulates there. Due to the water pressure of the pool water and the capillary phenomenon, there is a case where a so-called soot leakage phenomenon occurs in which water spills inside the roof and causes rain leakage.
[0003]
For these problems, install a snow stop on the roof to prevent snowfall, install a net of metal, etc. to prevent snowfall from clogging the valley and form an ice bank, or install panels, etc. Such measures are taken.
[0004]
For example, a snowfall prevention device in which a net is installed along the upper surface of an inclined roof of a house has been proposed (see, for example, Patent Document 1).
