Description

  The present invention relates to a rain gutter attached to the eaves of a folded-plate roof, and more particularly to a rain gutter with an icicle prevention function that covers the eaves of the folded-plate roof so that the melted snow will not freeze and form ice columns in the gutter.

Conventionally, eaves are attached to the eaves of the folded-plate roof in the snowy country, but the eaves attached to the eaves are attached to the lower side of the eaves so as not to be destroyed by the snow sliding down the roof.
Since the eaves are attached to the lower side of the eaves, a drainage hole is provided at the bottom of the valley of the folded plate roof to collect rainwater in the eaves.
With this structure, the melted snow was frozen in the winter and closed the drainage hole, and the ice column dropped from the eaves beyond the drainage hole, causing a fall accident and was dangerous.
In order to prevent this, an eaves for folded plate roof formed so as to cover the eaves of the folded plate roof is known (see Patent Document 1).
The above-mentioned known technology is formed so as to secure a continuous waterway space in the direction of girder and to cover the eaves of the folded plate roof and to insert the eaves of the folded plate roof from the side and A mounting opening communicating with the water channel space, and the mounting opening includes an upper opening edge that is fixed to the upper surface of the folded plate roof, and an lower opening edge that is fixed to the lower surface of the folded plate roof. And an eaves for a folded plate roof that is formed at the upper edge portion of the opening with a snow stop portion that rises upward and extends in the direction of girder.
In addition, a drain pipe heater for preventing freezing of a vertical drain pipe connected to an eaves bowl developed by the present applicant is known (see Patent Document 2).

  The present invention is an icicle prevention function that can be improved to cover the eaves of the folded-plate roof, instead of the existing eaves that freeze ice on the eaves that are attached to the eaves of the folded-plate roof, forming an icicle. The purpose is to obtain a rain gutter.

The rain gutter with an icicle prevention function of the present invention includes a mounting support plate fixed on a mountain portion of the folded plate roof along the roof inclination direction so as to project from the eaves of the folded plate roof, and a protruding tip of the mounting support plate A substantially V-shaped rain gutter cover fixed to be a drain gutter along the girder direction, a heater extending along the girder direction at the inner bottom of the gutter cover, and the rain Cover the eaves of the folded plate roof between the eaves cover and the wall surface of the house to cover and insulate, and cover the eaves of the folded plate roof and the upper opening of the gutter cover along the girder direction. A roof cover made of polycarbonate plate, and a cover made of PVC sheet spanned between a substantially V-shaped inner surface upper part of the rain gutter cover and a trough of the folded plate roof, and the gutter cover is covered by the gutter cover. And the gap between the folded plate roof and the valley.
In addition, the gutter cover is assembled from an upper gutter structure and a lower gutter structure which are divided into two parts, and overlaps the mounting support piece fixed to the mountain part of the folded plate roof at the longitudinal end of the rectangular gallium. The upper engagement piece bent in this manner, the long side wall extending downward from the upper engagement piece with a predetermined interval, and the lower engagement piece bent in the same direction as the upper engagement piece from the lower end of the long side wall A lower rain gutter structure and a longitudinal end portion of a rectangular PVC steel plate bent inward at right angles to form an upper mounting piece, and a long side wall is formed at a predetermined interval downward from the upper mounting piece. Subsequently, the bottom portion is formed by bending it into a V shape, and further forming a lower attachment portion by horizontally bending in the same direction as the upper attachment piece.

The rain gutter with an icicle prevention function of the present invention has a gutter cover made of a PVC sheet spanned between a substantially V-shaped inner surface upper part of the gutter cover and the eaves of the folded board roof, and the rain gutter cover and the folded board roof. Since the gap between the eaves and the eaves is closed, the flow of water from the folded plate roof to the gutter cover is made continuous so that the water does not stop, and ice pillars are formed at the eaves of the folded plate roof. Can be prevented.
Furthermore, since water that has flowed continuously from the folded plate roof to the gutter cover accumulates at the V-shaped top of the gutter cover, and a heater is installed in the pooled portion, freezing can be further prevented.
Further, since the gutter cover is assembled from the upper gutter structure and the lower gutter structure which are divided into two parts, the installation work is simple and efficient.
