Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a snow-melting roof structure in a house. More specifically, the present invention relates to a snow-melting roof structure capable of uniformly melting snow on a roof.

[Conventional technology]

2. Description of the Related Art Conventionally, snow removal work in a snowfall area has been physically difficult and dangerous. Therefore, various methods have been devised for melting snow on the roof. One of them is to arrange a hot wire or a heat pipe on the roof and drop it while melting snow.
Or there is a method of mechanically scraping snow.

[Problems to be solved by the invention]

However, there are drawbacks that the mechanical method requires a large-scale device and reduces the degree of freedom in design and design of the roof. In the case where a hot wire is used, there is a disadvantage that the running cost is increased. Further, in the case of a heat pipe, there is a disadvantage that the snow near the heat pipe is melted only by laying the heat pipe, and in the case of heavy snow, the snow is hollowed out.

[Means for solving the problem]

According to the present invention, in order to eliminate such drawbacks, piers made of a metal material having good heat conductivity are arranged at predetermined intervals on a roof foundation, and hollow pipes for passing a heat medium between the piers are arranged and fixed. At the same time, the hollow pipe is buried with mortar for storing and dispersing the heat of the heat medium and protecting the hollow pipe, and the roof material is arranged on the mortar and the pier via a protective sheet, and the heat generated by the heat medium The present invention proposes a snow melting roof structure that disperses and stores heat in a mortar to melt snow in a wide area and also enables snow melting on a pier.

〔Example〕

Hereinafter, the snow melting roof structure according to the present invention will be described in detail with reference to the drawings. FIG. 1 is an explanatory view showing a typical example of the snow-melting roof structure.
As shown in FIGS. 1 (a) to 1 (c), it is composed of a rafter 1, a field board 2, a waterproof sheet 3, and a heat insulating material 4. 5
Is a lath material, the entire surface of the roof base A or the pier 6
The mortar 8 to be described later is fixed on the roof foundation A. 6 is a pier,
This is for fixing the roof material 9. In addition, the crosspiece 6 is made of a material having good thermal conductivity, for example, a steel material such as a C-shaped channel, a Z-shaped steel, a grooved steel, or a metal material such as an extruded aluminum product.
It is arranged at a predetermined interval in accordance with the roof material 9 on the upper side. This is because the heat from the heat medium flowing through the hollow pipe 7 is conducted to the roofing material 9 even through the pier 6 and the snowmelt is transferred to the roofing material 9.
This is for performing the entire process. Numeral 7 denotes a hollow pipe which is disposed between the crosspieces 6 as shown in FIG. 3 so as to uniformly supply the heat medium supplied from the heat medium supply device to the entire surface of the roof, and forms a circulation path. It is arranged and fixed as follows. As the material of the hollow pipe 7, a copper pipe, a pipe made of a general steel material, whose outer surface is rust-proofed, or a synthetic resin pipe or the like, optionally with a cross-sectional shape,
It is arbitrary, such as a circle, a triangle, and a rectangle, and it is of course possible to arrange only a portion in contact with the mortar 8 as a copper pipe having good heat conductivity, and to arrange the other portions as an iron pipe or a synthetic resin pipe. In the portion where the hollow pipe 7 comes into contact with the outside air, the hollow pipe 7 is covered with a heat insulating material to prevent heat dissipation. In addition, the hollow pipe 7 can be disposed, for example, such that the eaves are dense and the ridge is sparse according to the roof portion. Reference numeral 8 denotes a mortar, which functions as a heat storage layer, a heat dispersion layer, and a protective layer, and also functions as a sound insulation layer and a backup layer. That is, the mortar 8 is planted between the crosspieces 6 so as to close the space between the roof foundation A and the protective sheet 10 and the hollow pipe 7 is buried. As the mortar 8, in addition to the mortar used to form a general outer wall, an anti-freezing agent is mixed into the mortar to prevent the mortar from being destroyed by freezing and thawing in winter, and to use an aggregate ( It is also possible to further increase the heat storage effect by increasing the amount of gravel and the like.
More specifically, by burying the hollow pipe 7, the mortar 8 prevents the heat medium in the hollow pipe 7 from exploding even if it freezes, stores heat by the heat medium, and has a wide area. By dispersing it in the roof material 9
This is to melt the snow on the entire surface and to eliminate the remaining snow due to cavitation. For example, FIG.
As shown in FIG. 1D, a metal roofing material, a metal roof tile, a roof tile, and the like are generally used.

The protective sheet 10 is disposed between the roofing material 9 and the mortar 8 and the pier 6 to enhance waterproofness, isolate the mortar 8 from the roofing material 9, and cause the alkali content of the mortar 8 to corrode the roofing material 9. It has a function of preventing such adverse effects as described above. The protective sheet 10 is, for example, asphalt felt, a synthetic resin sheet (polyethylene sheet, polyvinyl chloride sheet, etc.), an inorganic foam sheet, or the like, like the waterproof sheet 3 used for the roof base A. Further, the hollow pipe 7 can be provided as shown in FIGS. 5 (a) and 5 (b). Note that it is also possible to circulate a cooled heat medium in the hollow pipe 7 in the summer to make use of the heat prevention effect.

〔The invention's effect〕

As described above, according to the snow melting roof structure of the present invention, the mortar functions as a heat storage and heat dispersing layer, so that snow melting can be performed reliably and stably. Since the pier is made of a material having good thermal conductivity, snow melting is performed on the entire surface of the roof, and residual snow due to cavitation can be removed. The mortar backs up the roofing material and prevents deformation of the roofing material even when working on the roof such as painting. It also has sound insulation due to the presence of mortar. Since the hollow pipe is embedded in the mortar, it does not burst even if the heat medium freezes. Since the roofing material is provided on the pier and the mortar via the protective sheet, the waterproofing property can be enhanced, and the alkali content of the mortar can be prevented from adversely affecting the roofing material such as corrosion. Effects such as
There are features.
