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.

[Prior Art] Conventionally, snow removal work in a snowfall area has been physically demanding 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. Moreover, when piers and rafters are installed on the roof base to fix the roofing material, the heat pipes
It was only possible to install between the rafters, and it was difficult to disperse and release the heat for snow melting uniformly over the entire roof.

[Means for solving the problem]

In order to eliminate such drawbacks, the present invention disposes a hollow pipe for circulating a heating medium for supplying heat required for snow melting on a roof base, provides a space for forming a mortar layer, and provides a roof material. A short fixing material for roof material (hereinafter, simply referred to as a fixing material) for fixing the fixing member is provided between the hollow pipes at appropriate intervals, and the hollow pipe is embedded and at least the upper surface of the fixing material is exposed. The mortar layer that was planted, and the roofing material that was arranged on the mortar layer via a fixing material,
By using a roofing material, mortar layer, and a protective sheet placed between the fixing materials, the hollow pipe can be freely laid, and the heat from the heat medium is widely dispersed in the mortar layer to ensure snow melting. The present invention proposes a snow-melting roof structure which can be performed, can further enhance waterproofness, and can prevent the alkali content of the mortar from adversely affecting the roof material such as corrosion.

〔Example〕

Hereinafter, the snow melting roof structure according to the present invention will be described in detail with reference to the drawings. FIG. 1 shows the snow melting roof structure,
A indicates a roof foundation, 7 indicates a hollow pipe, 8 indicates a mortar layer, and 9 indicates a roofing material. FIG. 3 shows a piping example of the hollow pipe 7, and 6 is a fixing member. That is, the roof base A is composed of, for example, rafters 1, a base plate 2, a waterproof sheet 3, a heat insulating material 4, and the like as shown in FIGS. 2 (a) to 2 (c). Reference numeral 5 denotes a lath material, which is provided on the entire surface of the roof base A or between the fixing members 6, and for fixing a mortar layer 8 described later on the roof base A. The fixing material 6 fixes the roofing material 9 via the protection sheet 10 and
It functions as a raising material for forming a void for forming the mortar layer 8 between the protective sheet 10 and the roof foundation A. More specifically, the fixing member 6 is a short rectangular member or a steel member, and is disposed between the hollow pipes 7 as shown in FIG. For this reason, piping of the hollow pipe 7 can be freely performed, and snow melting design can be performed according to the shape of the roof and the location of the house. In addition, fixing material 6
It is also possible to use the remaining material generated when forming the frame of a house. The hollow pipe 7 is a boiler,
A heat medium (antifreeze, gas, etc.) supplied from a heat medium supply device such as a heat pump is supplied to the entire roof.
For example, it is arranged and fixed so as to form a circulation path as shown in FIG. The hollow pipe 7 may be made of any material such as a copper pipe, a pipe made of a general steel material, the outer surface of which is rust-proofed, a synthetic resin pipe, or the like. Of course, it is of course possible to arrange only a portion in contact with the mortar layer 8 as a copper pipe having good heat conductivity, and to arrange another portion 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. Further, the hollow pipe 7 is connected to a roof base A through a fixture B as shown in FIG.
It is also possible to fix on top. The mortar layer 8 functions not only as a heat storage layer, a heat dispersion layer, and a protective layer, but also as a secondary function as a sound insulation layer and a backup layer. That is, the mortar layer 8 is implanted so as to close the space between the roof base A and the protective sheet 10 and bury the hollow pipe 7. In this case, as shown in FIG. 5, planting is performed so that the upper surface 6a of the fixing member 6 is exposed. As the mortar layer 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, It is also possible to increase the amount of materials (such as gravel) to further enhance the heat storage effect. More specifically, the mortar layer 8 embeds the hollow pipe 7 to prevent the heat medium in the hollow pipe 7 from bursting even if it freezes, store heat by the heat medium, and By dispersing the snow over a wide area, the snow is melted on the entire surface of the roofing material 9 and the remaining snow due to cavitation is eliminated. The roofing material 9 is, for example, a metal roofing material, a tile, a metal-formed tile, a single material, or the like, as shown in FIGS. 6 (a) to 6 (i), and is generally used.

The protective sheet 10 includes a roof material 9, a mortar layer 8, and a fixing material 6.
The mortar layer 8 and the roofing material 9 are separated from each other, and the mortar layer 8 and the roofing material 9 are separated from each other to prevent the alkali content of the mortar layer 8 from adversely affecting the roofing material 9 such as corrosion. . 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. 7 (a) and 7 (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 layer functions as a heat storage and heat dispersing layer, so that snow-melting can be performed reliably and stably over the entire roof. Since the fixing member has a short shape, the pipe of the hollow pipe can be freely formed, and the pipe having a layout according to the snow melting design can be formed. The mortar layer backs up the roofing material and prevents deformation of the roofing material even on the roof such as painting. It also has sound insulation due to the presence of the mortar layer. Since the hollow pipe is buried in the mortar layer, it does not burst even if the heat medium freezes.
The remaining material can be used as the fixing material, which is economical.
Since the protective sheet is provided between the roof material, the mortar, and the fixing material, the waterproof property can be enhanced, and the alkali content of the mortar can be prevented from adversely affecting the roof material such as corrosion. There are effects and features such as.
