Abstract

PURPOSE:To permit the free piping arrangement of hollow pipes and surely melt snow by forming grooves or holes on a fixed member and arranging the hollow pipes and fixed members in crossing and planting mortar and arranging roof members on the mortar. CONSTITUTION:In order to firmly laying mortar 8 on a roof ground A, a latch member 5 is arranged on the whole surface of the roof ground A or between the fixed member 6. Then, a groove or hole is formed on the fixed member 6 for fixing a roof member 9. Then, a hollow pipe 7 for feeding a thermal medium supplied from a thermal medium feeding machine onto the whole surface of the roof is arranged so as to cross the fixed member 6 through the holes or grooves of the fixed member 6. Then, the mortar 8 is plated between the fixed members 6 so as to close the the space between the roof ground A and the roof member 19, and the hollow pipe 7 is embedded. Therefore, snow is molten on the whole surface of the roof member 9, and the residual snow due to the cavity formation can be molten.

Description

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

[Conventional technology]

Conventionally, snow removal work in snowy regions has been physically demanding and dangerous work. Therefore,
Various methods have been devised to melt snow from roofs. One method is to install a heat wire or heat pipe on the roof to melt the snow while it is being removed, or to mechanically shovel the snow down.

[Problem to be solved by the invention]

However, the mechanical method has the disadvantage that the equipment becomes large-scale and the degree of freedom in designing the roof is reduced. Furthermore, when a hot wire is used, there is a disadvantage that running costs are high. Furthermore, in the case of heat pipes, if the heat pipes were simply installed, the snow would melt only in the vicinity of the heat pipes, and in the case of heavy snow, there was a disadvantage that the pipes would become hollow. Furthermore, if a crosspiece or attached rafter is installed on the roof base to secure the roofing material, the heat pipe can be attached to the crosspiece or rafter.
It could only be placed between the attached rafters, making it difficult to distribute and release heat for snow melting uniformly throughout the roof.

[Means to solve the problem]

In order to eliminate such drawbacks, the present invention forms grooves or holes in fixing materials such as crosspieces and attached rafters for fixing roofing materials, and provides a hollow pipe for a heat medium to supply heat for snow melting. By placing the hollow pipe across the fixed material, burying it in mortar, and placing the roofing material on top of this, the hollow pipe can be used regardless of the type of roofing material or the location of the fixed material. We propose a snow-melting roof structure that can be freely piped, disperses heat from a heat medium over a wide area using mortar, and can reliably melt snow.

〔Example〕

The snow melting roof structure according to the present invention will be explained in detail below using the drawings. Figure 1 shows the above-mentioned snow melting roof structure, and A
7 indicates the roof base, 7 indicates the hollow pipe, 8 indicates the mortar, and 9 indicates the roofing material. Moreover, FIG. 2 is an example of piping of the hollow pipe 7,
6 is a fixing member.

That is, the roof base A is composed of rafters 1, sheathing boards 2, waterproof sheets 3, and heat insulating materials 4, as shown in FIGS. 3(a) to 3(C), for example. Reference numeral 5 denotes a lath material, which is disposed on the entire surface of the roof base A or between the fixing materials 6, and is used to securely install mortar 8, which will be described later, on the roof base A. The fixing material 6 is for fixing the roofing material 9, and functions as a raising material for planting the mortar 8 between the roof base A and the roofing material 9. This fixing material 6 is made of wood, as shown in FIGS.
These are Z-shaped steel, C-shaped steel, etc., and are provided with grooves 6a or grooves 6b. That is, the hole 6a and the groove 6b are used as the fifth hole when installing the hollow pipe 7 as shown in FIG.
As shown in the figure, a hollow pipe 7 is provided so as to be disposed across the fixing member 6. Therefore, the piping of the hollow pipe 7 can be freely performed without being affected by the presence of the fixing member 6, and the snow melting design can be performed according to the shape of the roof and the location conditions of the house. The hollow pipe 7 is used to supply a heat medium (antifreeze, gas, etc.) supplied from a heat medium supply device such as a boiler or a heat pump to the entire roof surface, and for example, as shown in FIG. The arrangement is fixed. The material of the hollow pipe 7 is as follows:
A copper pipe, a general steel pipe whose outer surface has been treated to prevent rust, or a synthetic resin pipe, etc., and its cross-sectional shape may be circular, triangular, square, etc., and the part that contacts the mortar 8. Of course, it is also possible to install only one part using a copper pipe with good heat conductivity and the other parts as iron pipes or synthetic resin pipes. In addition, the hollow pipe 7 is covered with a heat insulating material to prevent heat dissipation at the portion where the hollow pipe 7 comes into contact with the outside air.

Furthermore, the hollow pipes 7 can be arranged densely at the eaves and sparsely at the ridges depending on the location of the roof. To explain further, the hollow pipe 7 can be disposed across the fixing member 6 through the hole 6a and the groove 6b, as described above, and the piping layout can be freely assembled. Further, the hollow pipe 7 can also be fixed on the roof base A via a fixture B as shown in FIG. Reference numeral 8 denotes mortar, which functions as a heat storage layer/heat dispersion layer and a protective layer, and also functions as a sound insulation layer and a back-up layer. That is, the mortar 8 is planted between the fixing materials 6 so as to close the space between the roof base A and the roof material 9, and the hollow pipe 7 is buried therein. Mortar 8
In addition to the mortar used to form general exterior walls, antifreeze agents are mixed into the mortar to prevent it from being destroyed by freezing and thawing in the winter.
It is also possible to further increase the heat storage effect by increasing the amount of aggregate (gravel, etc.). To explain further, by burying the hollow pipe 7, the mortar 8 prevents it from bursting even if the heat medium inside the hollow pipe 7 freezes, stores the heat from the heat medium, and spreads over a wide area. This is to melt the snow over the entire surface of the roofing material 9 and eliminate snow remaining due to cavitation. The roofing material 9 is, for example, a metal roofing material, a tile, a metal molded tile, a shingle material, etc., as shown in FIGS. 7(a) to 7(i), and is used for boat fishing.

What has been described above is only one embodiment of the snow melting roof structure according to the present invention, and as shown by dotted lines in FIG. It is also possible to strengthen the waterproof property and to isolate the alkaline content of the mortar 8 from the roofing material 9. The protective sheet 10 may be asphalt felt, a synthetic resin sheet (polyethylene sheet, PVC sheet, etc.), an inorganic foam sheet, etc., similar to the waterproof sheet 3 used for the roof base A. Further, the hollow pipe 7 can also be arranged as shown in FIGS. 8(a) and 8(b). In addition, it is also possible to circulate a cooled heat medium in the hollow pipe 7 during the summer season to help with the heat protection effect.

〔Effect of the invention〕

As explained above, according to the snow melting roof structure according to the present invention, since the zero mortar functions as a heat storage and heat dispersion layer,
Snow melting can be performed reliably and stably over the entire roof surface.

■Since holes and grooves are formed in the fixing material, the hollow pipe can be laid across the fixing material, allowing for free layout of the hollow pipe according to the snow melting design. 0 mortar backs up the roofing material and prevents the roofing material from deforming during work on the roof such as painting. It also has sound insulation properties due to the presence of mortar. ■Since the hollow pipe is buried in mortar, it will not burst even if the heat transfer medium freezes. It has the following effects and characteristics.
