DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for preventing icing of a roof for a cold region, which drains snowmelt water on a roof without icing, and a method of installing the device.

[0002]

2. Description of the Related Art In cold regions such as Hokkaido, snowmelt water on the roof freezes and grows thickly like an ice embankment, or hangs down as a icicle on the eaves. Social problems that frequently cause phenomena and accidents such as falling snow and ice that cause personal injuries have become major problems. In view of such a problem, Japanese Patent No. 29669 is disclosed.
Japanese Patent Publication No. 98 discloses a method and an apparatus for preventing icing of a roof for a cold region, which drains the snow-melting water at a temperature at which the snow-melting water is frozen without freezing or forming icicles.

According to the invention described in this publication, a rain gutter or drainage channel of an outside air blocking type is provided along the eaves, and a snow fall prevention frame plate is provided on the eaves adjacent to the rain gutter or the drainage flow passage. It stands upright with the drainage channel. Further, at the lower end portion of the snow fall prevention frame plate connected to the rain gutter or the drain channel, an inflow port for passing snowmelt water on the roof to the rain gutter or the drain channel is opened, and the rain gutter or the drain channel is opened. A heating element is attached to the roof to prevent freezing of snowmelt water. The rain gutter or the drainage channel can be opened and closed by a lid so that outside air can be shut off. Then, when the temperature sensor detects the temperature of the frozen outside air of the snowmelt water, the heating element is energized to heat the snowmelt water. In addition, the heat of the heating element in the rain gutter or the drain channel is trapped in the outside air shielding type rain gutter or the drain channel,
The icing on the surface of the lid is prevented.

However, the device described in this publication is
As described above, since the snow fall prevention frame plate and the rain gutter or the drainage channel are integrally mounted on the eaves, it is difficult to install the anti-icing device on the eaves, and the rain gutter or the drainage channel is not provided. There is a problem in that work at a high place involves a great danger because it becomes a heavy object. In addition, since the gutter or drain channel and the snowfall prevention frame plate are integrated, the gutter or drainage channel and the snowfall prevention frame plate must be accurately manufactured in advance according to the shape and dimensions of the eaves and roof. However, there is a problem that the cost is rather increased.

[0005]

A member such as the packing 19 may be interposed between the member b.

Next, the installation procedure of the rain gutter 10 having the above configuration will be described.
A description will be given together with an embodiment of a method of installing a gutter. FIG.
FIG. 4 is an exploded perspective view illustrating a rain gutter installation procedure according to an embodiment of the rain gutter installation method of the present invention. Since the basic configuration of the rain gutter shown in FIG. 2 is the same as that of the rain gutter shown in FIG. 1, the same portions and the same members are denoted by the same reference numerals and description thereof will be omitted.

An auxiliary member 17 formed in advance in accordance with the mounting angle of the rain gutter 10 is mounted on the eaves 31 of the roof 3 on which the rain gutter 10 is mounted. The auxiliary member 17 includes an adhesive, a nail,
It can be attached to the eaves 31 with bolts or the like. Also,
The auxiliary member 17 is preferably formed of a material having a low thermal conductivity, such as wood or resin, in order to prevent the heat of the rain gutter main body 11 heated by the heating element 12 from radiating to the roof 3 side. .

When installing the rain gutter 10, first, the rain gutter main body 11 having the heating element 21 is attached to the eaves 31 of the roof 3 with screws 16a. The gutter body 11 is attached to the eaves 31
, The heating element 21 may be attached to the rain gutter main body 11. When attaching the rain gutter main body 11 to the eaves pier 31 via the auxiliary member 17, the rain gutter main body 11 is attached so that the end face of the auxiliary member 17 and the side surface of the rain gutter main body 11 come into close contact with each other. Is fixed to the roof 3 at a predetermined angle. Next, the lid 13 and the snow fall prevention plate 15 are connected with the screw 16c.
Then, the lid 13 and the snow fall prevention plate 15 are connected to the rain gutter main body 11.
And placed on the fly portion 32, and the gutter main body 1 is fixed with screws 16b.
1, and the snow fall prevention plate 15 is fixed on the roof 3 with bolts 33a. Finally, the bracket 21 is engaged with the upper bent portion 15b of the snow fall prevention plate 15 so that the snow fall prevention plate 15 does not fall outside the roof 3.

According to the above embodiment, each member (the rain gutter main body 11, the open / close lid 13, and the snow fall prevention plate 15) can be individually assembled to the icing prevention device 1, so that the work is easy. And since each member is also relatively lightweight, the danger of work at a high place is small. Furthermore, the assembling operation can be performed by a small number of people, and the dimensions of the members 11, 13, 15 and the like can be easily adjusted on site according to the shape of the roof 3 and the dimensions of the eaves 31. There is also.

Although the preferred embodiment of the present invention has been described, the present invention is not limited to the above-described embodiment and can be variously modified within the scope of the present invention. For example, in the above description,
Although the roof 3 having the roof 2 has been described as an example, the rain gutter of the present invention can be applied to other roofs to which the rain gutter is attached at the tip. The fastening means is screws 16a, 16b, 16c.
However, other fastening means such as bolts and rivets may be used. In addition, about the opening / closing lid 13,
It is preferable to use bolts and thumb screws in addition to the screws 16b and 16c so that the lid 13 can be easily removed from the rain gutter body 11.

The heating element 25 provided on the roof 3 is preferably a sheet heating element. According to this configuration, it is possible to prevent freezing of snowmelt water at the eaves portion and to perform snowmelt at the eaves portion, thereby reducing the load on the eaves portion and preventing damage to the eaves portion due to the load. There is an advantage. Examples of the sheet heating element include a stainless steel tape heater, a stainless steel heater, an aluminum etching heater, a carbon heater, a self-temperature controllable carbon heater, a ceramic heater, a self-temperature controllable ceramic heater, and a heating wire processed into a sheet shape. And various known ones can be used. Among them, a stainless steel tape heater, a self-temperature controllable carbon heater, and a self-temperature controllable ceramic heater are particularly preferable.

In the above description of the method of installing the rain gutter, the lid 13 is attached to the snow fall prevention plate 15 and these are attached to the rain gutter main body 11 and the like. The bracket 13 is first fixed to the roof 3, and then the opening / closing lid 13 is attached to the snow fall prevention plate 15 and the rain gutter main body 11 by screws 16 c and screws 16 b.
You may make it attach with.
