Abstract

PURPOSE:To prevent snow coverage by providing a snow melting portion having a heat generating body on a coping for covering the top face of the parapet body of a building, detecting a snow fall condition and heating the snow melting portion. CONSTITUTION:A coping 30 made of aluminum, etc., is assembled to a bracket 20 provided on the top face of a parapet body 10 so as to cover the top face 12, and a case 56 in which a linear heat generating body 60 is built in is installed on the outer surface 36 of the coping 30 via a support leg 52. A temperature sensor for detecting outer-air temperature and a snow-fall sensor are connected to a control circuit. With an outer-air temperature below a defined value and, as snow fall is detected, the heat generating body 60 is electrified via the control circuit to generate heat so that snow in the vicinity of the snow melting portion 50 is molten and allowed to flow down along the slope of the top plate portion 32 of the coping 30 to be drained equally to rain. Hence, snow coverage on the surface of the coping can be prevented.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is applicable to, for example, a parapeller built around the edge of a hill house or balcony.
In particular, the present invention relates to a snow melting device for melting snow that accumulates on the surface of the hat.

Existing Techniques> Regarding the above-mentioned parapet frame, it is generally practiced to cover the top surface 112 of the parapet frame with a cape 130, as shown in FIG. 14, for example, for the purpose of waterproofing the building. In other words,
Brackets 120 are fixed to the top surface 112 of the parapeller L-flit body 110 at predetermined intervals along the top surface 112, and caps 130 made of a light alloy material such as aluminum are attached to the top surface of the brackets 120. It is attached so as to continuously cover the surface 112.

With the configuration shown in FIG. 14, the purpose of waterproofing the building can be fully achieved.

However, when snow accumulates on the surface of the cap 130 in a snowy region as shown in FIG. 14, the cap 130 receives a considerable snow load. For example, 50cm~
It has been confirmed that when there is 200 cm of snow, a 22 cm wide Kasagi can receive snow carts weighing 4.0 kg to 170 sho per meter of length.

<Problems to be Solved by the Invention> As shown in FIG. 14, when a large amount of snow accumulates on the surface of the cap 130, the cap 130 may be deformed at locations other than the bracket 120 due to the snow load described above. Furthermore, there is a danger that the snow mass S in the portion extending from the upper surface of the cap 130 to the outside of the building may fall.

Therefore, as a countermeasure against such snowfall, the present applicant has developed a device in which a heating element such as a panel heater that generates heat using electricity is housed inside the cap, and is configured to perform the snow melting function. (For example, Japanese Patent Application 1986)
-07! b377 (see specification and drawings).

However, when storing the above-mentioned heating element inside the Kasagi,
There are problems with its secondary nature, and it is difficult to adapt to existing Kasagi, and periodic inspections and maintenance work are also complicated.

<Means for Solving the Problems> In order to solve the above problems, the present invention is configured as follows.

In addition, a snow melting section is installed on the outer surface of the cap, which is attached to cover 10 sides of the building's parapet frame. The heating element housed in the snow melting section is configured to generate heat to heat the snow melting section when a predetermined electric power is supplied thereto.

In addition, the snow melting power supply means detects the snowfall state and supplies power corresponding to the snow melting power supply means to the heating element.
, is becoming a sea urchin.

<Function> According to the above configuration, the heat generated by the heating element housed in the snow melting section melts the snow that has fallen near the snow melting section, thereby preventing snow from accumulating on the surface of the cap. be done. In addition, since the snow melting section is installed on the outer surface of the Kasagi, its construction is easy and the construction period can be shortened.

Moreover, snow melting power corresponding to snowfall conditions is outputted to the heating element by the first stage of snow melting section horn supply. Therefore, snow melting can be carried out effectively without wasting electricity.

. <Example> Next, an example of the present invention will be described with reference to FIGS. 1 to 13.

First Embodiment First, in FIG. 1, which shows the snow melting device for Kasagi in longitudinal section, there are a plurality of brackets 20 on the top surface 12 of the parapet frame 10 constructed on the lff1 of the building or around the periphery of the balcony. 1 and each bracket h arranged at predetermined intervals along the continuous direction of this parapet frame 10.
20 is fixed to the parapet frame 10 by screws 16, and each screw 16 connects the parapet 1 to the frame 10.
The anchor plug 14 is screwed into the anchor plug 14, which is previously driven into the interior of the anchor plug 14.

The above brackets i to 20 have a web 22 that contacts the sacral surface 12 of the parapet frame 10 and is fixed with the screws 16 in the 1ζ state, and extends from both ends of this web 22 to the parapet 1 along the side wall of the frame 10. It includes a locking side piece 24 that extends integrally downward in the drawing.

Further, a support piece 26 is formed on the upper surface of the bracket 20 at a position on the left side in the drawing of the crucible crown 22, which integrally projects downward therefrom and which provides a cushion on the upper surface. Similarly, at the boundary between the right side portion of the web 22 in the drawing and the following right locking side piece 24, a supporting protrusion 27 having a cushion on the upper surface is integrally bent so as to protrude downward in the drawing. ing. However, support piece 2
The protrusion dimension of 6 is set to be much larger than the protrusion dimension of the support protrusion 27.

The cap 30 is made of a light alloy such as aluminum or stainless steel, and has a cross-sectional shape shown in FIG. 1 and a constant length in the continuous direction of the parapet frame 10. In other words, this Kasagi 30 is
and side plate portions 34 integrally extending downward in FIG. 1 at both ends thereof, and locking claws 34 . a is integrally formed.

In order to attach the cap 30 to the parapet frame 10, the cap 30 is attached to the brackets 1 to 20 so as to cover the brackets 1 to 20 from above. At this point, the side plate portions 34 of the Kasagi 300 are guided by both locking side pieces 2/I of the brackets i to 20, and are slightly elastically deformed in the expansion direction. And finally Kasagi 3

For this control circuit 72, there is a temperature sensor 74 that detects the outside air temperature and outputs an electric signal corresponding to the outside air temperature or stops this, and a temperature sensor 74 that outputs an electric signal when snowfall is detected, or outputs an electric signal corresponding to the outside air temperature. A snowfall sensor 76 for stopping the snowfall is electrically connected to each of the snowfall sensors 76 . In addition, snowfall sensor 7
6 has a built-in small heater to prevent the snow that sometimes pours into the sensor 76 from melting, and by detecting the water content when the snow melts with this heater, it outputs the aforementioned snowfall signal. It is configured as follows.

When the temperature detected by the temperature sensor 74 is, for example, 3°C or less, and the snowfall sensor 76 detects the snowmelt water, and both sensors 74 and 76 output electricity No. 49, respectively. , the control circuit 72 sends a power output command signal to the output circuit 78.
