Abstract

[PROBLEMS] To use a snow cover panel that can be easily installed on an existing roof by using a general snow stop fitting, and to use a heat transfer panel with an excellent snow melting function, so that the snow on the entire roof can be treated by melting the snow. A possible eaves snow melting device is provided. A frame for fixing heat transfer panels 1a and 1b having a snow stop function using a simple snow stop fitting 6 is fixed to a roof steel plate 10 near the eaves in parallel with the eaves at an appropriate interval. Then, snow is melted by the heat source liquid circulated through the hollow portion 3 formed in the center portion of the panel. Moreover, the windbreak space comprised with a heat-transfer panel is formed to the vicinity of ridge 13, and snowmelt water is allowed to flow down to the ridge without refreezing.

Description

The present invention relates to an apparatus for preventing snow falling from a roof and melting snow with a snow stopper having a snow melting function in which snow that has accumulated is installed at the eaves.

It is well known that a large amount of snow in a heavy snowfall area has a big impact on social life. There is. Snow removal is a task that depends on human power for the most part, is forced to take a lot of time and labor, and is a dangerous task.
In order to solve such problems, various snow melting devices and snow melting structures that can melt and remove the snow on the roof without performing snow removal have been proposed.

Patent No. 3384961 Japanese Patent No. 3326599 Japanese Patent Application No. 2015-27045

(Patent Document 1) has a simple structure and can prevent the snow falling near the eaves from falling, provides a good snow stop for the entire roof, and stops snow and rainwater that has melted snow. There is a snow stop that can flow down from the eaves without any problems. However, it did not have a function for removing snow stopped by a snow stopper.

In (Patent Document 2), a corrugated plate is provided below a snow-stopping and snow-melting body in which a cross-section is a substantially triangular shape and a snow-stopping and snow-stopping body in which a wire mesh is stretched on a frame having a predetermined interval is attached. An attached snow eaves for roof eaves is provided. However, without using a heat source for snow removal, the snow removal effect has been limited to exhibiting the snow melting effect by sending wind to the snow pile supported by the through hole provided in the snow stop plate portion.

(Patent Document 3) provides a snow melting roof material using a heat transfer panel in which heat to a heat radiating plate is propagated only by heat conduction by flowing a heat source liquid in a hollow portion formed integrally with the heat radiating portion. ing. However, since the installation area is large, the installation cost is high, and there is no snow stop effect, and a snow stop device is required to prevent snow fall.

The present invention can be installed on the eaves of the roof by using a general snow stop fitting, and is installed on the frame along the eaves. The snow stop plate is constructed of a heat dissipating panel integrated with the hollow portion for the heat source circulating liquid, so that the snow covered snow is efficiently melted, and the space constituted by the frame body and the heat dissipating panel is cold air. The purpose is to provide a snow melting device having a wind-proof function for preventing cold air to prevent the outside air from flowing down to the ridge without refreezing the snow-melt water.

Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings. The technical scope of the present invention is not limited to this embodiment.
First, the heat transfer panel will be described.
1 is a schematic plan view showing a heat transfer panel, FIG. 2 is a schematic cross-sectional view taken along line AA in FIG. 1, and FIG. 3 is a schematic cross-sectional view taken along line BB in FIG. 1, 2, and 3, 1 is a heat transfer panel, 2 is a heat transfer part of a heat transfer panel 1 formed of aluminum alloy in a plate shape, and 3 is a width direction of one surface of the heat transfer part 2 It is the hollow part for heat-source circulating liquid of the heat-transfer panel formed in the center part.
At both ends of the hollow portion 3 of the heat transfer panel 1, a sealing plug having 14 heat source circulating fluid piping connection ports and 15 heat source circulating fluid piping are installed, and the heat of the heat source fluid is heated from the hollow portion. Because it is propagated by heat conduction to the heat sink made of aluminum alloy with conductivity, the heat transfer part ensures a uniform temperature distribution, and at the contact part with the snow, large heat dissipation per unit area occurs and snow melting is performed .

Next, the structure of the eaves snow melting device will be described.
FIG. 3 shows a schematic diagram of installation of the eaves snow melting device, and FIG. 4 shows a conceptual diagram of the structure of the device. 3 and 4, 1a is a heat transfer panel installed on the ridge side, 1b is a heat transfer panel installed on the eaves side, and 4 is a frame of a snow melting device for mounting the heat transfer panels 1a and 1b. 5 is a side cover attached to both side surfaces of the triangular structure formed by fixing the heat transfer panel 1 to the frame 4, and 11 is between the ridge side heat transfer panel 1a and the roof steel plate 9 A gap, 12 is a gap between the eaves side heat transfer panel 1b and 10 roof steel plates for eaves, and 13 is a gutter.
With this structure, the space formed by the ridge-side heat transfer panel 1a, the eaves-side heat transfer panel 1b, and the side cover 5 constitutes a substantially closed space that covers the roof steel plate 9 and the roof steel plate 10 for eaves. Snowmelt water generated in the ridge-side heat transfer panel 1a is not exposed to the cold wind outside air but flows down without being re-frozen and led to the trap.
6 is a snow stop fitting, 6a is a connection portion of the snow stop fitting to the roof material, 9 is a roof steel plate, 6b is a bolt for fastening the snow stop fitting to the roof steel plate of 9, and 7 is a frame 4 of the snow melting device. Bolts for connecting the snow stop device 6, 8 screws for fixing the heat transfer panels 1a and 1b and 4 snow melting device frame, 12 a pipe plug for sealing both ends of the heat transfer panel cavity 3 Reference numeral 13 denotes a pipe joint and pipe for supplying and discharging the circulating heat source to and from the 12 pipe plugs.
With this structure, the frame body 4 of the snow melting device is first connected to the snow stop fitting, and then fixedly connected to the roof steel plate in parallel with the eaves at appropriate intervals on the roof.
After the frame body 4 is installed, the ridge-side heat transfer panel 1a and the eaves-side heat transfer panel 1b are fixed by the fixing screws 8 as snow stoppers.

Next, installation of the eaves snow melting device will be described.
As shown in FIG. 3, in this apparatus, the heat source liquid pipe is processed in a sealed space without protruding from the end face of the heat transfer panel, and the pipe to the heat source supply destination is piped from the optimum position of the side cover 5. Therefore, since the piping is not exposed around the snow melting device, it is possible to prevent the occurrence of wiggling caused by the piping.
