In terms of density, a material having a foaming ratio of about 20 to 40 times is used from the viewpoint of density and mechanical strength, heat insulation, and cost.

  The heat medium circulation pipe 6 is continuously arranged on the upper surface of the heat insulating layer 5 separated by the rafters 2 as shown in FIGS. 1 and 2, for example, for supplying a heat medium supply path 6a and a return path 6b. It constitutes a heat medium circulation pipeline that forms a reciprocation. More specifically, the heat medium circulation pipe 6 is made of a kind of bendable synthetic resin, for example, polyethylene, polybutene, and the like, and the heat medium circulation pipe path is formed by a heat-sealed seamless structure or one piece. . As a result, leakage of heat medium such as hot water, simplification of construction, and correction of the heat medium circulation pipe 6 to an accurate position are facilitated, and the formation of the heat medium circulation pipe path as designed is facilitated.

Useful. Note that the mounting tool 8 is made of a band-shaped metal or resin and sandwiches the outer periphery of the heat circulating medium pipe 6 and both ends thereof are fixed integrally with the base plate 4 by fixing members C such as nails.

  The heat conduction layer body 9 is a heat storage layer for efficiently conducting heat from the heat medium circulation pipe 6 to the roof A through the field board 11 and the waterproof sheet 12, and the heat conduction material 9a is a waste material or the like. Linear or net-like short metal scraps, such as iron, stainless steel, aluminum, or a mixture of two or more of them are stacked in a bag 14 as shown in FIG.

  Further, the heat conductive layer body 9 is provided in the flat rectangular space 10 between the upper surface of the heat insulating layer body 5 provided on the side surface 2a of the rafter 2 and the upper surface of the base plate 4 and the lower surface of the field plate 11 in the heat insulating layer body 5. A heat supply space 10a is formed on the fixed heat medium circulation pipe 6 or in the space where the heat medium circulation pipe 6 is disposed. Further, the heat conductive layer body 9 is formed by filling the heat conductive material 9a or the like, and is compressed as necessary, and the heat conductive material 9a and the heat medium circulation pipe 6 are brought into close contact with each other to improve the heat conduction efficiency.

   The field board 11 uses one kind of plywood, slate board, wood wool cement board, sizing board, rough board and the like. The waterproof sheet 12 is made of one or more types such as asphalt felt and other synthetic resin sheets, and functions as a secondary waterproof layer for the roof material 13.

  The roof material 13 functions as a heat dispersion layer and a heat conduction layer for melting snow. For example, a metal plate such as a color steel plate, a titanium steel plate, a copper plate, a stainless steel plate, an aluminum plate, or a clad steel plate is formed into a predetermined shape. Thus, the base plate 11 is installed so as to increase the contact area with the upper surface of the base plate 11. The roofing material 13 may be a slate plate or asphalt single plate.

  Next, the snow melting roof structure 1 according to the present invention has a large number of flat rectangular spaces 10 on a gable roof A as shown in FIG. 3, for example, and the eaves B of the roof A of the flat rectangular space 10. The heat supply space 10a is formed only in the portion located in the position. Specifically, the rafters 2 are long ones having a rectangular cross section with a height of about 90 mm and a width of 45 mm, arranged in parallel at a pitch of 455 mm, and the height of each fixed rafter 2 is fixed. A batten 3 having a long section of 20 mm square is fixed in parallel with the lower end of each rafter 2 at a position about 20 mm from the lower end in the vertical direction.

A heat insulating layer 5 is formed by cutting a heat insulating plate made of and fitting into a flat rectangular space 10 formed between the rafters 2. In addition, as shown in FIG. 2, partition plates 5 a that divide the flat rectangular space 10 formed between the adjacent rafters 2 perpendicularly to the longitudinal direction of the rafters 2 are arranged at intervals. In this way, air leakage in the flat rectangular space 10 is prevented and suppressed.

  Next, a heat medium circulation pipe 6 made of polybutene resin having a diameter of about 14 mmψ is raised from the interior of the roof A at the end of the eaves B on the roof A through the base plate 4 and the heat insulating layer 5 (not shown), A heat medium circulation pipe 6 is disposed throughout the eaves B. The heat medium circulation pipe 6 is composed of a supply pipe 6a and a return pipe 6b as shown in FIG. 2, and these are alternately arranged so that, for example, a U-shape is repeated, thereby improving the efficiency by effectively utilizing the heat efficiency. . For this purpose, a loop-shaped first-stage heat medium circulation pipe path 6 and a second-stage heat medium circulation pipe path 6 are disposed over the entire eaves vicinity.

  Next, in order to form the heat conductive layer 9, the heat conductive material 9a, for example, about 0.3 mm in diameter and about 1 to 20 mm in length, is formed between the heat insulating layer 5 and the rafter 2 and between the heat medium circulation pipes 6. The flat rectangular space 10 is laid and laminated so that the flat rectangular space 10 is filled at least to some extent by dispersing iron wire scraps or metal wire nets. Note that the heat medium circulation pipe 6 may be put in a net-like bag 14 made of a heat conductive material or a synthetic resin material as shown in FIG. 5 so as not to be damaged by the heat conductive material 9a or to be separated. .

  On the rafter 2 constructed in this manner, the field board 11 is laid and fixed, the waterproof sheet 12 is mounted thereon, a secondary waterproof layer is formed, and the roofing material 13 is mounted on the roof B from the eaves B. The roof A is constructed by sequentially laying out one letter.

     What has been described above is the best mode of the snowmelt roof structure according to the present invention. The dimensions of each member described above can be selected according to the application. For example, as shown in FIG. 4, the heat conductive layer body 9 is not the entire flat rectangular space 10 but the rafter 2 and the heat medium circulation pipe 6. It is also possible to suppress or prevent corrosion of the heat conductive layer 9 due to condensation by filling the diatomaceous earth powder or block having a characteristic of absorbing and releasing moisture between them to form the auxiliary heat insulating layer 5b. Further, as shown in FIG. 5, a heat conduction material 9a is deformably housed in a bag 14 of an object and interposed between the heat medium circulation pipes 6, or although not shown, a heat conduction layer in which the heat medium pipe 6 is housed and arranged. The body 9 can also be configured. Furthermore, the distribution of the heat medium circulation pipes 6 may be arranged as shown in FIG. 6, for example, or the number and arrangement of the heat medium circulation pipes 6 may be other than U-shaped although not shown.

Although this snowmelt roof structure is incorporated and installed in a state, it is used when there is or is expected snow. When, for example, warm water, which is a heat medium, is passed through the heat medium circulation pipe 6 when there is snow, heat is transferred from the heat medium circulation pipe 6 to the heat conduction layer body 9, and the heat supply space 10a is warmed. 11, the heat of the field board 11 warms the roofing material 13 and melts the snow on it. The heat from the heat medium circulation pipe 6 is hardly transmitted in the direction of the base plate 4 by the heat insulating layer 5 and warms the heat supply space 10a. That is, the air inside and outside the previous heat conductive layer body 9, for example, the air between the heat conductive materials 9a is warmed, and the base plate 11 is warmed.
The heat circulation pipe 6 does not have to be disposed on the entire roof A, but simply reaches the eaves B portion so that the heat circulation pipe 6 descends from the top, so that it plays a sufficient role.
