DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention 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.

[0002]

2. Description of the Related Art Heretofore, 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. As one of them, there is a method in which a hot wire or a heat pipe is provided on a roof to melt snow while dropping it, or a method to mechanically scrape snow.

[0003]

However, there are drawbacks that the mechanical method requires a large-scale apparatus and that the degree of freedom in design and design of the roof is reduced. 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. For this reason, Japanese Patent Application Laid-Open No. 2-186073 is disclosed. However, since this structure is a structure formed by wet construction, there remains a problem that the construction period becomes longer.

[0004]

In order to solve the above-mentioned problems, the present invention uses a backing plate made of a thermally conductive material such as a slate plate, a concrete plate, and the like. On the lower ground, in the horizontal direction, the edges are abutted, so that they are superimposed in a staircase from the eaves in the ridge direction, fixed and used as a backup and heat distribution layer, and a roofing material for steps is mounted on this backup and heat distribution layer. By laying a heat medium pipe in a space with a triangular cross section between the roof base and the backing plate, heat from the heat medium pipe is supplied to the entire exterior part by the backup and heat dispersion layer, and the cavity The present invention proposes a snow-melting roof structure capable of improving the workability by enabling the snow melting without the phenomena of phenomena and the construction by the dry method.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a snow melting roof structure according to the present invention. FIG. 1 is an explanatory view showing a typical example of the snow melting roof structure. In FIG.
Denotes a backup and heat dispersion layer (hereinafter, simply referred to as a dispersion layer), C denotes an exterior part, and 7 denotes a heat medium pipe.

As shown in FIGS. 2A and 2B, the roof foundation A is composed of rafters 1, a base plate 2, a heat insulating layer 3, and a waterproof sheet 4. In other words, (a) shows a case where the base plate 2 is laid on the rafter 1, the heat insulating layer 3 is provided on the base plate 2, and the heat insulating layer 3 is provided.
Roof base A having a structure in which a waterproof sheet 4 is disposed thereon, (b)
Shows a roof foundation A in which a heat insulating layer 3 is formed on a rafter 1 and a field board 2 and a waterproof sheet 4 are laid on the heat insulating layer 3 in this order. This heat insulating layer 3 is formed by a sheathing insulation board, a plastic foam board, or the like.
The purpose is to block heat inside and outside the house, so that almost all of the heat from the heat medium pipe 7, which will be described later, contributes to snow melting. Of course, in the summer, even if the roof is heated by the sun, heat is prevented from being transmitted to the interior of the house, which also helps to prevent the temperature inside the house from rising.

The dispersion layer B is formed by laying a large number of plate-like backing plates 5 on the roof foundation A, backing up the roof material 6 constituting the exterior part C, and performing work on the roof and snow accumulation. Even if a load is applied as described above, the roof material 6 is prevented from being deformed and the heat from the heat medium pipe 7 is dispersed.
This is for transmitting to the entire surface of the roofing material 6. That is, the backing plate 5 is an inorganic plate such as a concrete plate or a slate plate, or a plate obtained by mixing metal fibers into a plastic plate, and has thermal conductivity. To explain further,
The backing plate 5 abuts the end face in the horizontal direction, and, as shown in FIG. 1, overlaps the long side surface with the lower backing plate 5 in the ridge direction from the eaves to form a step-like shape and a triangular shape with the roof base A. Is fixed so as to form the space α.

The exterior part C is formed by arranging a step-like roof material 6 on the dispersion layer B. The roofing material 6 is formed by bending and pressing a metal plate such as a color steel plate, a stainless steel plate, an aluminum plate, a titanium steel plate, a copper plate, a clad steel plate, or by extruding a metal material. As shown in FIGS. 3A to 3F, a roof having a stepped appearance is formed. In the figures, (a) to (c) are fixed to the roofing material 6 itself using nails or the like directly, and (d) to (f) are fixed to the roofing material 6 using hooks (not shown). Representatives are shown.

The heat medium pipe 7 circulates a heat medium (antifreeze, gas, etc.) supplied by a heat medium supply device such as a boiler, heat pump, or solar, and supplies heat necessary for melting snow. The material for the heat medium pipe 7 is a copper pipe, a synthetic resin pipe, or the like, and has an arbitrary cross-sectional shape such as a circle, a triangle, and a square. More specifically, the heat medium pipe 7 is laid in the space α, or is fixed by the metal fitting 8 as shown in FIG. The heat supplied by the heat medium pipe 7 is
The heat medium pipe 7 is directly transmitted to the dispersion layer B via the air in the space α or when the heat medium pipe 7 is in contact with the backing plate 5 as shown in FIG. As a result, snow melting will take place over a wide area.

The above is only an example of the snow-melting roof structure according to the present invention. In the roof base A, a composite plate of a heat insulating material and a hard plate material can be used as the heat insulating layer 3 and the field plate 2 can be eliminated. It is. 5 as a backing plate 5
As shown in (a) and (b), it is also possible to provide a concave portion 9 in at least one of the overlapping portions of the long side surfaces and use it as a guide for polymerization. Furthermore, it is also possible to circulate a cooled heat medium in the heat medium pipe 7 in the summer to make use of the heat prevention effect.

[0011]

As described above, according to the snow-melting roof structure of the present invention, since the heat from the heat medium pipe is dispersed in the dispersion layer, snow-melting can be performed on the entire roof. The dispersion layer acts as a backup for the exterior,
Even when working on the roof, deformation of the roof material can be prevented. The snow-melting roof structure of the present invention can be performed in a dry manner and has good workability. There are effects and features such as.
