DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and a structure of a snow-melting roof used for a house in a snowy country where the amount of snow is large. The present invention also relates to a method and a structure for a snow melting roof capable of melting snow with a solar pipe, a heat pipe, an electric heater, or the like, removing snow from the roof by wind, and melting snow even with wind at a temperature of zero or more.

[0002]

2. Description of the Related Art In a snowy country with a large amount of snow, if a certain amount of snow is piled on a roof, a heavy load is applied to a house due to the weight of the roof. . In this conventional snow removal operation, workers climb on the roof, scoop,
The snow was cut off with a snow dump, etc., and the block-shaped snow was dropped, which was extremely primitive. And the snow dropped from the roof was moved to the river using wooden gutters. Such snow removal work had to be repeated many times during the winter in houses in heavy snowfall areas, placing a heavy burden on snow country residents.
In addition, due to soaring labor costs and labor shortages these days,
Even if you want to drop the snow, it is often impossible to implement it because people do not gather. For this reason, if a large amount of snow accumulates in a short time, it may not be possible to remove snow during that time, causing the house to collapse due to the weight of the snow,
There were also personal injuries.

As described above, there are many inconveniences such as an increase in labor cost, labor shortage, and difficulty in the work of removing snow, and a structure of a house for solving these problems has been desired. From such a viewpoint, various developments have been made on snow-melting roofs in which when snow accumulates on the roof, the snow is sequentially melted by heat or the like, and the snow is naturally removed without human power. This snow-melting roof can be roofed with a special structure before building the house.
It was able to automatically remove the snow without human intervention, which was convenient for houses in snowy countries. However, many conventional snow-melting roofs have a structure in which a heated water pipe and a heater are arranged at the bottom of the roof and the backside of the roof is heated to melt a part of the snow that has accumulated. The snow melted water was flowing down along the slope of the roof.

[0004]

In such a conventional roof against snow melting, the appearance is often a flat roof inclined toward one or both sides, and a plurality of flat plates are required for assembling the roof. The metal plate was engaged with a goby or the like. In roof of this structure, working facilities Engineering is complicated, with take working days, the heat conduction in the goby portion was made worse. In addition, since the purpose is to melt snow with a heat source such as a hot water pipe or a heater without using solar heat in fine weather, a heat source for heat generation is required, and operation costs are high.

[0005] Therefore, there has been a demand for the development of a snow-melting roof that uses the heat generated in a room and transmits the heat to the shingle along the slope of the attic, thereby reducing operating costs. Further, the be easily assembled on site has it <br/> the facilities Engineering, construction method can shorten the construction period is desired. Furthermore, depending on the roof structure,
It is preferable that a device capable of melting snow with solar heat is used.

Next, FIG. 4 shows a state in which the snow melting roof in this embodiment is assembled. In FIG. 4, a house 1 constructed of a lightweight steel frame is assumed, and the roof 5 of the house 1 is assumed.
H steel material 55 as a purlin (haze) member
Are placed at intervals. This H steel 55 is used to house 1 composed of a light-gauge steel, results in the use of wooden haze instead of an H steel 55 when the house 1 is of wooden buildings.

When assembling the roof 5 in this embodiment, the tight frames 12 are arranged at equal intervals on the flat portion of the upper surface of the H steel material 55, and these tight frames 1
2 Since (the gradient direction of the roof 5 perpendicular direction) length direction of H steel 55 are spaced, Ru Tei their tight frame 12 to the lower surface of the roof 5 is arranged in a grid. Then, bolts (not shown) are inserted into the screw holes 43 of each tight frame 12.
The tight frame 12 is fixed to the H steel material 55 with these bolts. Note that the tight frame 12 and the H steel material 55 may be fixed by welding .

On the tight frame 12 thus arranged in a lattice pattern, a long roof material 11 is aligned in the inclination direction, and a plurality of roof materials 11 are arranged side by side to roof the roof 5. Will be. In this case, the roofing materials 11 arranged in parallel as shown in FIG. 4 are installed between the tight frames 12 and 12, and the corners of the inclined portions 21 of the roofing materials 11 are brought into contact with the standing claws 47 of the tight frame 12. And the roofing material 11 is held so as not to fall from the tight frame 12.
When the roofing material 11 is arranged between the tight frames 12 and 12 in this manner, a gap is formed between the outside of the rising portion 23 of each roofing material 11, and the suspender 15 is inserted into the gap from above. Fit it. Although not shown, a threaded hole is formed in the bottom part 25 of the suspender 15, and after the mounting screw 44 is inserted through the threaded hole, a nut 56 is inserted into the mounting screw 44.
By screwing the
Fixed to Thereafter, the upper part of the retaining clips 15 are grooves of shaped "U" is opened, the bottom 28 of the cap 16 in the groove, to insert the side portion 29, the outer side surface and the side surface portion 26 of the side surface portion 29 are brought into close contact with the inner surface, brought into close contact with the lower surface of the mosquitoes were main portion 30 on the upper surface of the fixed portion 27. Then, press-contact parts 3 on both sides
Crimping 1 inside each roofing material 11 by engaging the contact portion 31 and the lower surface of the fixed portion 24, retaining clips 15, Ru cap 16 is fixed so as to be integrated. in this way,
Three members are connected together the pressure contact portion 31 by crimping, yet since the retaining clips 15 is fixed to the H steel 55 by mounting screws 44, roofing 11
Is fixed at the mounted position. After this, cap 1
When the lower opening of the makeup cap 17 is pushed downward from above the back 6, the return portion 34 acts as a spring to open a gap, so that the return portion 34 comes into close contact with the lower surface of the press contact portion 31 due to its elasticity. The makeup cap 17 is connected to the upper surface of the cap 16. The makeup cap 17 covers the bottom portion 28 and a groove on the upper surface of the cap 16 formed by the bottom portion 28 to protect rainwater and dust from entering.

If the slope of the roof 5 is long, one roof material 11 is connected to the next roof material 110 to be extended. The top surface of the waterproof seal 50 is brought into close contact with the inner peripheral surface of the roofing material 110 by covering the front end of the roof 11 from above. After this, both roof materials 1
Both roofing materials 11 and 110 are kept with
Is fixed by caulking the fixing portion 24 with the cap 16. In this manner, the roofing material 11 and the roofing material 110 can be sequentially extended in the length direction, and the roof can be roofed. Since the waterproof seal 50 has elasticity, it is crushed and deformed, so that the waterproof seal 50 comes into close contact with the outer peripheral surface of the roofing material 11 and the inner peripheral surface of the roofing material 110, and both the roofing materials 11, 1
Rainwater and dust are prevented from entering the attic through the gap of 10. FIG. 5 is a cross-sectional view of the assembled roof 5 shown in FIG. 4 cut vertically.

In the roof 5 covered with a plurality of roofing materials 11 assembled as shown in FIGS. 4 and 5, snow that has accumulated can be melted by heat generated indoors. First, the air in the house 1 is warmed by heat generated from a heating device in the room or heat generated from a human body, and the air lightened by the temperature rise flows through a duct facility provided on the lower surface of the roof 5. As a result, the lower surface of the roofing material 11 is heated. For example, if the snow cover on the top surface of the roof is 30 cm or more, the surface temperature of the roofing material 11 (the temperature at the lower part of the snow cover) is about zero even if the outside air temperature is -2 to -3 degrees. For this reason, if the temperature of the air generated from the interior of the house 1 and flowing through the lower surface of each roofing material 11 is 2 to 3 degrees, the lower surface of the snow covered on the roofing material 11 is heated and changes to water. For this reason, when changing from solid snowfall to liquid snowmelt water, the snowmelt water flows even with a slight inclination, and this snowmelt water flows down the valley 22 of the roofing material 11 and flows downward. Fall from the edge to the ground. Thus, snow melting and snow falling can be performed simultaneously. In addition, since the mountain 20 formed on the roofing material 11 extends upward in a mountain shape, the heat exchange area from the air in contact with the lower surface of the mountain 20 is large, so that the roof 20 has a flat shape. The heat exchange rate becomes extremely high. Further, when the sunlight after snow is irradiated onto the surface of the roof 5, crests 20, absorbs solar heat at the surface of the inclined portion 21, will be transfer heat to snow, it is snow-melting the snow by solar Thermal efficiency can be further improved.

Further, the combination structure of the rising portion 23, the hanging member 15, the cap 16, and the decorative cap 17 forms a three-dimensional structure in which these are slightly T-shaped when viewed from the side. Since the upper surface supports the snow cover like an umbrella, the separation of the snow cover and the snow melting water is easily performed.
At the same time, the snowmelt water separated from the snowpack flows through the valleys 22, so that the lower part of the snowpack does not absorb the snowmelt water, and the weight of the snowpack itself does not increase by sucking the snowmelt water. For this reason, even if a large amount of snow is piled up on the roof 5 in a short time, the weight of the snow itself is only reduced, so that the load applied to the roofing material 11 is reduced by the amount of snowmelt flowing down, and the load is increased. Can be prevented.

When the air heated in the room comes into contact with the lower surface of the roof material 11 which is cold, water vapor in the air is condensed due to a decrease in temperature, and water droplets adhere to the lower surface of the roof material 11. The water droplets condensed on the lower surface of the roofing material 11 flow downward according to the inclination of the curved surface inside each of the inclined portions 21, and flow water grooves 48 provided on the left and right of the gutter 13.
Collected in. The water droplets collected in the water channel 48 flow out along the inclination direction of the roof 5 and are discharged from the lower end of the roof 5 in the same manner as snow. The dew condensation generated on the roofing material 11 is concentrated at the corners of the inclined portion 21 and the valley portion 22, but the dew condensation is collected in the concave portion 45 formed in the tight frame 12 on the way, After passing through the communication hole 46, it similarly falls into the flowing water groove 48.

As described above, the snow can be removed from the roof by melting the snow from the lower or upper part of the snow and transforming it into water. However, the conditions of the site of the house 1 (when there is no other house around) Or if you have a large site)
In some cases, when melting snow, the snow can be slid along the slope of the roof 5 and dropped to the ground. Also,
Snow melting since the joint located between the roof member 11 and the roofing material 110 (the gap roofing 11 and roof member 110) meltwater, although sometimes rainwater flows, which is in the gap is provided with a waterproof seal 50 Water and rainwater are prevented from entering by the waterproof seal 50. Should the roofing material 11 and the roofing material 11
The snowmelt water and rainwater sucked into the gap 0 are collected by the water stop grooves 51 and flow along the inclination direction of the water stop grooves 51,
The water drops from the lower drain hole 52 into the running water groove 48 and is similarly collected.

FIG. 6 shows another embodiment of the present invention. In this case, a long copper pipe 72 is inserted into the “ U ” -shaped cross-sectional space formed by the bottom portion 28 and the side surface portion 29 of the cap 16.
After the copper pipe 72 is arranged, when the decorative cap 17 is put on the upper surface of the cap 16 from above, the decorative cap 17 covers the upper surface of the cap 16 by the elasticity of the winding portion 33. Hot water flows in the Y direction below the X direction in FIG. 6 which is above the gradient of the copper pipe 72, and the cap 16, the makeup cap 17, and the suspension 15 are heated by the hot water, and the snow covered on the roofing material 11 is snowed. Can be forcibly melted. In this way, by flowing the hot water through the copper pipe 72, the melting of snow can be hastened regardless of indoor heat or solar heat. Further, not limited to the embodiments by heat conduction by the copper pipe 72, for example, it can be configured to be housed electric heater and sheathed heater in the cavity of the cap 16 to obtain the same effect.

FIG. 7 shows a third embodiment of the present invention, and shows a configuration in which snowmelt water and rainwater are collected at the eaves of the roof 5. In this case, a roof 5 is provided at the upper part of the house 1, and the roof 5 shows the gable type house 1 in which the center is raised and the roofs 58 and 59 are inclined in the left-right direction. A gutter 60 is fixed to the gable side of both roofs 58 and 59 covering the house 1, and a narrow water stop 61 is fixed to the eaves of the roofing material 11 constituting both roofs 58 and 59. .

FIG. 8 shows the internal structure of the house 1 in the third embodiment. In this case, columns 64 and 65 are erected on all sides and in the center as in a normal house, and a large beam 66 is placed on the upper portions of the columns 64 and 65. Both ends of this large beam 66 are projected outside the outer side surface of the pillar 64, and project outside the outer wall of the house 1. A plurality of purlins 67 are placed on the upper surface of the large beam 66 at intervals, and the purlins 6 on the central pillar 65 are located.
7 is located at the highest position, and is sequentially and gently inclined in the left-right direction. A plurality of roof materials 11 are installed in parallel on these purlins 67, and the roof 58 and the roof 59 are formed by the roof materials 11. A water stop 61 is fixed to the tip of the large beam 66 projecting laterally from the outer wall surface as a blindfold of the eaves,
The inside of the water stop 61 is trough 68 cross section is the shape of the "U" is is fixed horizontally. The terminal end of the roofing material 11 is located above the groove of the gutter 68 that opens upward in a “ U ” shape.

FIG. 9 shows the positional relationship between the end of the roof material 11 and the gutter 68 on the roof 58 described above.
At the tip of the large beam 66 projecting outward from the outer surface of the column 64, a narrow water stopper 61 is fixed with its length direction horizontal so that its plane is vertical. A cover plate 69 is fixed to the upper end of the stopper 61. And
Located between the main house 67 and water and stopper 61, the chute 68 extending in the horizontal direction is disposed on the upper surface of the large beam 66. The gutter 68 is, for example FRP, has been formed of aluminum or the like, the cross section has a shape of opening upward "U",
It is inclined in one direction. In this configuration, the roof 5 of FIG.
Falling on the upper surface of the roof material 11 is accumulated on the surface of the roofing material 11. When heat is generated inside the house 1 as described above, the indoor heat heats the lower surface of the roofing material 11 by the duct device and melts the snow on the roofs 58 and 59. The snowmelt water flows in the direction of the water stop 61 along the slope of the roofing material 11, and the snowmelt water falls at the end of the roofing material 11. However, the gutter 68 is located at the lower end of the roofing material 11.
Is installed, the snowmelt falling from the roof material 11 is collected by the gutter 68. Since the gutter 68 is tilted in one direction at the eaves, it is possible to collectively drain the gutter 68 at the end thereof with a gutter or a duct.

As described above, according to the present invention, a plurality of metallic roofing materials can be arranged side by side on a roof set of a house with a simple structure. In assembling the roofing material, both ends of the roofing material arranged on the left and right can be fixed only by caulking with caps, and the roofing work process can be shortened. And since the shape of each roofing material is bent in a waveform, the total area is large and the heat exchange rate is high, so that it is efficient to melt snow.
Further, since the cross-sectional shape as the arc-shaped mountain shape, improves the durability to support snow and snow, it is possible to enhance the load bearing properties compared to the roof construction of a flat shape. Furthermore, since a space is formed between the roof member and the roof member, it is easy to arrange a heater and a hot water pipe for heating, and it is easy to cover the arranged space with the cover. .
