DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a snow melting roof used in a house in a snowy country with a large amount of snow, and in a region where the roof has snow due to the large amount of snow, heat from the inside of the house and solar heat or to remove the snow from the roof by the wind with melting snow, to a structure of a snow melting roof can Rukoto also to snow melting by temperature is zero degrees or the wind.

[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 lack of manpower these days, there are many cases where it is not possible to want to remove snow. For this reason, if a large amount of snow accumulates in a short period of time, it may not be possible to remove the snow during that time, causing the collapse of the house due to the weight of the snow and causing personal injury.

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 possible to automatically remove snow without the need for human intervention, which was convenient for a house in a snowy country. But,
Many conventional snow melting roofs have a structure in which a hot water pipe and a heater are placed at the bottom of the roof to heat the back of the roof to melt part of the snow that has accumulated, and the melted snow changes to water. As a result, the snowmelt water flowed down along the slope of the roof.

[0004]

In such a conventional roof against snow melting, the appearance is often a flat roof structure inclined toward one or both sides, and a plurality of flat plate-like roofs are used to assemble the roof surface. The metal plates of No. 3 were engaged with a goby or the like. The roof of this structure, is complicated work of facilities Engineering,
As the working days take, heat conduction in the goby portion deteriorates. 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.

[Action]

[0007] In the present invention, the valleys left and right on both sides by bending under the elongated steel sheet, a rising portion at both ends of the valley using consolidated <br/> roof material. Prepare a plurality of these roofing materials,
The combined tilt direction and their length direction of the roof assembly arranged to be adjacent. The caulking portions at the respective side ends of these adjacent roof members are engaged with and fixed to the T-shaped portions of the tight frame fixed to the roof set of the mother's house. Therefore, previously the mother house roof sets keep secure the tight frame at predetermined intervals, then the roofing material disposed along its length direction in the inclined direction, tight each roofing material in the crimped portion at both ends Can be easily assembled by connecting to the frame.

[0008] Heat generated from a heat source such as a stove or a human body circulates from the indoor to the attic, and flows inside the mountain of each roofing material. Since the heated air has a low specific gravity, it flows upward along the slope of the mountain, and the heat of the air is transferred to the snow from the roof material. For this reason, the lower part of the snow covered on the roof is melted at the portion in contact with the roofing material, and is turned into water. This snowmelt water flows along the roof slope and falls to the ground. In addition, since the surface of the bent mountain portion of each roof material is lifted high and the solar heat is absorbed and the heat is transmitted to the snow cover, the snow can be melted by the solar heat applied during the snowfall.

[0009]

Next, an embodiment of the present invention will be described with reference to the drawings. In the present embodiment, a case where the structure of the snow melting roof of the present invention is applied to a one-sided slope single-flow roof type house will be described. However, the structure is not limited to this example, and any structure may be used as long as any roof surface of the house is inclined in one direction, such as a gable roof, a factory roof, or a butterfly roof. The same action and effect are produced, and the present invention is not limited to this embodiment.

In FIG. 1, reference numeral 1 denotes a house having a snow melting roof. In this house 1, the roof 5 has a so-called one-sided roof structure in which the roof 5 is inclined to one side. The side of the house 1 is an outer wall 2 covered with a heat insulating material, and the outer wall 2 is provided with windows 3 for lighting. Further, a door 4 through which people enter and exit is attached to a part of the outer wall 2. As this house 1 is often used in snowy countries, the floor, the outer wall 2, etc. are made of highly heat-insulating material, and the heat generated indoors does not leak to the outside to reduce energy loss. Has a heat retaining structure. In addition, since the air flows inside the house 1, the lower surface of the roof 5 is provided with duct equipment so that the air can flow. For this reason, the air is warmed by the heat generated by the heating equipment used inside the house 1 and the heat generated by the human body, and is raised to the ceiling due to the difference in the specific gravity of the air, and is placed on the lower surface of the roof 5. The roof 5 is heated from the bottom by flowing the duct equipment and exchanging heat. Since this duct structure that allows warm air to circulate is well known in the art, description of this duct structure is omitted in this embodiment.

Next, FIG. 2 shows the snow melting roof of this embodiment.
1 shows a first embodiment of the structure . In this figure 2 shows the main member for use in snow-melting roof, showing an exploded state of the respective members before the facilities Engineering begins.

[0012] In the facilities Engineering of the snow melting roof, roof material 11 was bending a thin steel plate, a house of the roof assembly (the main building (also
,), The base of the roof composed of rafters, etc., small
(Also referred to as the roof ), a metal tight frame 12 fixed to the upper surface of the roof, a gutter 13 for bending thin-walled steel plates to drain the condensed water, and the tight frame 12 is deformed by a load when combined with the gutter 13. It is composed of a reinforcing rod 14 for preventing the occurrence of damage. Assemble these four members
By to be matched seen, facilities Engineering of snow melting roof is performed.

First, the roof material 11 is formed by bending a long thin steel plate. Although only a part of the roof material 11 is shown in FIG. 2, it actually has a long shape along the length direction. It has a. Horizontally arranging a plurality of roofing material 11 by aligning each longitudinal, roof 5 can葺Kukoto These roofing 11. The roofing materials 11 are connected and arranged to protect rain and snow from blowing into the house 1.

The roofing material 11 is formed by bending an elongated thin steel plate to the left and right at the center in the longitudinal direction. First,
Mountain part 1 is bent from the center of the thin steel plate to the left and right in a semi-circular shape.
6 are formed, and on the left and right of the mountain portion 16, there are inclined portions 17 which are symmetrical and form a smooth flat surface. A valley portion 18 extending in the horizontal direction is formed at the lower end of each of the inclined portions 17, and a rising portion 19 oriented in the vertical direction is connected to both ends of each valley portion 18, respectively. Further, a caulking portion 20 having a C-shaped cross section that opens downward is formed at the upper end of one rising portion 19 (left side in FIG. 2).
Ah is, Ru other rising portion 19 caulking portion 21 with an opening cross-section has a C-shaped at the upper end of (right side in FIG. 2) downward is formed Citea. Both caulking portions 20 and caulking portions 21 are symmetrically arranged with respect to the mountain portion 16, and the outer diameter of the caulking portion 21 matches the inner diameter of the caulking portion 20, so that the inner space of the caulking portion 20 is formed. The caulking portion 21 can be inserted into the. This is because when the roofing materials 11 are arranged in parallel, the caulking portion 21 is inserted and combined in the C-shaped space formed in the caulking portion 20.

Next, the tight frame 12 is formed by bending, pressing and welding a slightly thick metal plate (not limited to this manufacturing method, it is also possible to integrally form it by casting). In this tight frame 12,
A lower portion thereof is a leg portion 23 formed in a slightly " U " shape, and a fixing piece 24 extending horizontally outward is connected to both left and right sides of the leg portion 23. The tight frame 12 is attached to these fixing pieces 24 by a roof set (such as a purlin or
A rafter. In this embodiment, it corresponds to the H steel material 33 described later.
It is opened the screw holes 25 for fixing to that). In addition, the surface of the tight frame 12 becomes a flat surface, and in the center of the upper surface,
A T-shaped portion 26 having a T-shaped cross section is vertically erected and fixed. The T-shaped portion 26 is fixed to the leg portion 23 by welding. The upper portion of the T-shaped portion 26 is a mounting portion 27 having a flat upper surface and extending in the horizontal direction, and the width of the mounting portion 27 is substantially equal to the inner width of the caulking portion 21. Further, on the upper part of the leg portion 23 and on the left and right sides of the T-shaped portion 26, a recessed portion 28 recessed downward is formed by press working or the like, and a communication hole 29 communicating vertically is formed in the center of the recessed portion 28. It has been opened. These recesses 28, communication
The hole 29 is made of a single material by press working.
You.

Next, the gutter 13 has a shape obtained by bending a thin thin metal plate made of metal, and the center of the cross section has a " U " shape opening downward. the left and right opening upward for flowing water in one direction
Flowing water grooves 31, 31 having a " U " shape are formed.
The length of this gutter material 13 is set to be substantially the same as the length of the roof material 11 and is arranged from the upper end to the lower end of the roof 5.

The reinforcing rod 14 is located at the center of the gutter member 13.
It is adapted to be fitted into a " U " -shaped opening cross section formed in a part, and the cross section has a rectangular shape.
The reinforcing rod 14 receives the load via the upper surface of the gutter member 13 when the load is applied to the tight frame 12, and prevents the tight frame 12 from being deformed by the load.

Next, FIG. 3 shows a state in which the snow melting roof in this embodiment is assembled. In FIG.
It is assumed that the house 1 is made of lightweight steel frame, and the H steel material 33 as a main (mist) member is laterally arranged on the lower surface of the roof 5 of the house 1. The H steel material 33 is used in the house 1 made of lightweight steel, but when the house 1 is a wooden structure, the same effect can be obtained even if the H steel material 33 is a wooden purlin. you.

In the first embodiment, when assembling the roof 5, the tight frames 12 are arranged at equal intervals on the flat upper surface of the H steel material 33, and the roof 5 is
Tight frame 1 in a straight line along the direction of inclination
Place two. Therefore, the tight frame 12
This means that they are arranged in a grid pattern on the roof set. Then, bolts (not shown) are provided in the screw holes 25 of each tight frame 12.
The H steel material 33 and the tight frame 12 are fixed with this bolt. The tight frame 12 and the H steel material 33
It can also be fixed by welding.

As described above, the long frame formed by bending is formed on the upper portion of the tight frame 12 arranged at regular intervals in a grid pattern.
The roofing material 11 is lined up and the roof 5 is roofed. In this case, the roofing materials 11 arranged in parallel as shown in FIG.
Of these, the caulking portion 21 of the roof material 11 arranged on the left side is fitted into the internal space of the caulking portion 20 of the roof material 11 on the right side.
With the two caulking portions 20 and 21 thus fitted together, the mounting portion 27 of the T-shaped portion 26 is inserted into the C-shaped internal space of the caulking portion 21, and then the caulking portion 2 is inserted.
0, the pressure is applied from the outside together with the caulking portion 21 to cause the caulking. By this processing, the T-shaped portion 26, the crimped portion 20, and the crimped portion 21 are integrally fixed, and these members do not come off. In this way, by caulking the caulking portion 20, the caulking portion 21, and the mounting portion 27, the rising portions 19 on both sides of each roofing material 11 are in close contact with the side surfaces of the T-shaped portion 26 and the valley portion 18 is formed. The lower surface is brought into close contact with the upper surface of the leg portion 23, and the entire roof material 11 is connected and fixed to the H steel material 33 fixed to the house 1. By sequentially performing such roofing work from the left side to the right side in FIG. 3, the long roof material 11 can be sequentially fixed to the roof part of the house 1. When the roofing materials 11 on both sides arranged in parallel are connected by caulking, the lower roofing material 11 is aligned in its length direction along the slope of the roof 5, and each roofing material 11 becomes parallel. It means that the arrangement is fixed. For this reason roof 5
Rainwater that has fallen on the surface of the water flows down from the upper part to the lower part of the groove formed by the valley 18. In the work of crimping the caulking portion 20, the caulking portion 21, and the mounting portion 27, a waterproof tape may be attached in advance to the upper surface of the mounting portion 27, and the waterproof tape may be caulked together to improve waterproofness. it can.

In the roof 5 formed by the plurality of roof members 11 assembled as shown in FIG. 3, snow accumulated can be melted by the heat generated from the room. First, the air in the room 1 is warmed by the heat generated by the heating equipment and the heat generated by the human body, and the air that has become lighter due to the temperature rise flows in the duct equipment provided on the lower surface of the roof 5, and as a result, the roof is heated. The lower surface of the material 11 will be heated. For example, if the upper surface of the roof 5 has snow of 30 Cm or more, the surface temperature of the roof material 11 (the temperature of the lower part of the snow) is about 0 degrees even if the outside air temperature is −2 to −3 degrees. . Therefore, if the temperature of the air generated from the inside of the house 1 and flowing on the lower surface of each roof material 11 is 2 to 3 degrees, the lower surface of the snow accumulated on the roof material 11 is melted and changed into water. Therefore, when the solid snow is changed to liquid water, the water can flow even with a slight inclination, the water flows through the valley portions 18 of the roof material 11 in the lower direction, and finally the roof material 11 Fall to the ground at the edge. Therefore, snow melting and snow removal can be performed simultaneously.
Further, since the mountain portion 16 formed by the roof material 11 extends upward in a mountain shape and has a large heat exchange area from the air in contact with the lower surface thereof, as compared with a flat roof. The heat exchange efficiency is extremely high, the amount of heat transferred to the lower surface of the snow is large, and the snow melting effect is high. Furthermore, when sunlight irradiates the surface of the roof 5 after snowfall,
The solar heat is transferred to the surfaces of the mountain portion 16 and the sloped portion 17, and the heat is transferred to the snow cover. Since the lower part of the snow cover can be melted by the solar heat, the thermal efficiency becomes higher.

When the snow is melted by heat, since the upper surface of the caulking portion 21 supports the snow like an umbrella, the snow and water are easily separated. At the same time, the water separated from the snow flows through this valley 18 and moves,
The lower part of the snow cover does not absorb water, and the weight of the snow cover itself is not increased by water. For this reason, even if a large amount of snow accumulates in a short time, the weight of the snow itself will only decrease.
The load applied to will be reduced by the amount of water flowing down, thus preventing an increase in load.

When the air warmed indoors comes into contact with the lower surface of the cold roof material 11, the water vapor in the air is condensed due to the temperature decrease, and water drops adhere to the lower surface of the roof material 11. The water droplets condensed on the lower surface of the roof material 11 are
It will flow downwards according to the inclination of the inside of each inclined portion 17, and will be collected in the flowing water grooves 31 provided on the left and right of the gutter 13. The water droplets collected in the running water groove 31 flow out along the inclination direction of the roof 5 and are discharged from the lower end of the roof 5 like snow. The dew condensation generated on the roofing material 11 flows along the corners of the inclined portion 17 and the valley portion 18, but it is collected by the concave portion 28 formed in the tight frame 12 in the middle and the communication hole 29. After that, it also falls into the flowing water groove 31 in the same manner. In this way, the snow can be removed from the roof by melting the snow from the bottom or top and converting it to water, but the conditions of the site of the house 1 (when there is no other house in the surrounding area Depending on the case where the site is secured), the snow can be slid along the slope of the roof 5 by melting the snow and dropped to the ground.

Next, FIG. 4 shows another embodiment of the present invention, which has both the effect of snow melting and the effect of silencing. In this case, the tight frame 12 has the same structure as that shown in FIGS. The members corresponding to the roof material 11 and the gutter material 13 in FIGS. 2 and 3 are the roof material 35 and the gutter material 36 in this embodiment.

The roofing material 35 in this embodiment also has a shape in which a long thin steel plate is bent at its center as in the above, and the bent center has an arc-shaped mountain portion 38.
The left and right sides are connected to the inclined portion 39 which is a smooth plane. In the lower part of the inclined portion 39, valley portions 40 formed in an arc shape are connected in an upward direction opposite to the peak portions 38. The rising portions 41 are connected to the tangents that are arcuate at both ends of the valley portion 40 so as to be vertical toward the upper side, and one rising portion 41 (left side in FIG. 4). ) Has a caulking portion 42 having a C-shaped cross section downward, and the other rising portion 41 (right side in FIG. 4) has a C-shaped cross section downward. A crimp portion 43 is formed. Therefore, in the cross-sectional shape of the roofing material 35, the mountain portion 38 at the center upper portion and the valley portions 40 at the left and right lower portions are S
The curve is formed so as to have a letter shape.

Further, the gutter 36 is for collecting the condensed water droplets, but the gutter 36 is different from the first embodiment shown in FIGS. 2 and 3 and has an elongated cross section " U " . It is formed in a V shape and is fitted into the lower opening of the tight frame 12. Therefore, in the second embodiment, the strength of the tight frame 12 is made sufficiently strong, and the reinforcing rod 14 in the first embodiment is saved.

FIG. 5 shows a cross section in which the roof member 35, the tight frame 12 and the gutter member 36 in the second embodiment are assembled and fixed to the upper surface of the H steel member 33. In this state, a plurality of roofing material 35 wipe the surface of the roof 5 as shown in Figure 5 to form an arc-shaped continuous pattern in which the wave-like, flat portions are extremely small. Therefore, even if rain or haze falls on the metal roofing material 35, there are few flat portions that come into contact with the roof material 35. Therefore, the rain or haze flows down to the valley portion 40 along the arcuate inclined surface. For this reason, the dropped force is laterally distributed as a component force and dispersed, and it is possible to reduce the high-pitched noise generated by the hail and rain peculiar to the metal roof. The theory that snow is melted and falls and the procedure for collecting the dew condensation caused by the temperature difference of the air are the same as described above.

Further, FIGS. 6 and 7 show a third embodiment of the present invention. In this example, the roofing material 4
5 and the tight frame 46 constitute a main member, and the gutter material 13 in the first embodiment and the gutter material 36 in the second embodiment described above are unnecessary.

The roof material 45 is formed by bending a long thin steel plate, and the center thereof has an arc-shaped mountain portion 48.
The left and right sides of the mountain portion 48 are formed with valley portions 50 each having a smooth flat surface. Vertically erected portions 51 are formed on both left and right ends of both valley portions 50,
On one end of the rising portion 51 (left side in FIG. 6) is formed a caulking portion 52 having a C-shaped cross section that opens downward, and on the other end of the rising portion 51 (right side in FIG. 6). Is formed with a caulking portion 53 having a C-shaped cross section that opens downward. The outer diameter of the caulking portion 53 is matched with the inner diameter of the caulking portion 52, so that the caulking portion 53 can be fitted inside the caulking portion 52. The shape of the roof material 45 has substantially the same cross-sectional shape as the roof material 11 in FIG. 2 described above. Also only, this roofing material 45
In the lower surface of the mountain portion 48, the inclined portion 49, and the valley portion 50, a heat insulating material 54 made of a heat insulating material such as synthetic resin or glass fiber is adhered. Therefore, the portion of the lower surface of the roof material 45 facing the inside of the house 1 is
The heat insulating material 54 is evenly spread over all the surfaces.

A house 1 with a snow melting roof according to the third embodiment
State of the construction stage in H steel 33 in the roof is as shown in FIG. In this FIG. 7, the tight frame 46
The fixing part 56 of the H steel material 33 is brought into close contact with the upper surface of the H steel material 33, and the screw hole 5
It is fixed to the H steel material 33 by passing a screw through 9. Therefore, many tight frames 46 are arranged in a grid pattern at equal intervals on the roof set of the house 1.
Then, the roof 5 can be roofed by aligning the length direction of the long roof material 45 with the inclination of the roof 5 and arranging a plurality of the roof materials 45 in parallel in the lateral direction. In this case, as described above, the caulking portion 53 is fitted into the internal space of the caulking portion 52, and then the mounting portion 5 is inserted into the internal space of the caulking portion 53.
Insert 8. Then, the caulking portion 52 and the caulking portion 53 are caulked from the outside, so that the roof material 45 can be fixed to the tight frame 46.

In the third embodiment, the warmed air generated in the room of the house 1 is insulated by the heat insulating material 54, and the heat in the room is not transmitted to the surface of the roof 5.
This is because the heat generated in the house 1 is not radiated to the outside, and the heat insulating property of the house 1 is enhanced so that the heat is not radiated to the outside. This is because the roof 5 must have the snow resistance and the snow melting effect at the same time in an area with a large amount of snow. That is, when the snow that has accumulated is melted and dropped on the ground, the dropped snow must be removed after that, so that the snow is first deposited on the roof 5 in the same manner as on the ground. After that, the sun's rays illuminate the surface of the snow, and the snow is melted by the heat of the sun to be removed as water. In addition, the geothermal heat generated from the ground also heats the snow from the lower part, and a part of it is blown away with the wind. Furthermore, if the wind blows on the snow when the temperature is above zero, the temperature of the wind can also melt the snow. Since the heat insulating material 54 is attached to the lower surface of the roof material 45, dew condensation does not occur on the lower surface of the roof material 45, and a mechanism for draining the condensed water droplets is not necessary in this embodiment.

Further, FIGS. 8 and 9 show a fourth embodiment of the present invention. In this embodiment, the rough structure is almost the same as that of the first embodiment shown in FIGS. Therefore, the tight frame 12, the gutter member 13, and the reinforcing rod 14 are the same as those in the first embodiment.

The fixing piece 24 of 3 is brought into close contact with the upper surface of the H steel material 33, and the screw hole 2
It is fixed to the H steel material 33 by passing a screw through 5. Therefore, many tight frames 12 are arranged in a grid pattern at equal intervals on the roof set of the house 1.
Then, the roof 5 can be roofed by aligning the length direction of the long roof material 71 with the inclination of the roof 5 and arranging a plurality of the roof materials 71 in parallel in the lateral direction. In this case, the fixing portion 78 of the roof member 71 on the left side of the drawing is brought into close contact with the side surface of the T-shaped portion 26 of the tight frame 12, and the L-shaped side surface is combined with the T-shaped portion 26. After that, on the right side of the figure, roof material 71
The caulking portion 77 is combined with the mounting portion 27 of the T-shaped portion 26, the mounting portion 27 and the top of the fixing portion 78 are wound by the caulking portion 77, and the caulking portion 77 is caulked from the outside, so that the left and right roof members 71, 71 and the tight frame 12 are connected and fixed.

Also in this fourth embodiment, as shown in FIGS.
In the same manner as in the above example, the heat generated inside the house 1 is applied to the roofing material 7
The lower surface of No. 1 can flow and melt the snow accumulated on the roof material 71. With this structure, it is not necessary to provide the C-shaped caulking portions 77 on the left and right ends of the roof material 71, and the roof material 71 can be easily manufactured.

Furthermore, FIGS. 10 and 11 show a fifth embodiment of the present invention. In this embodiment, the rough structure is almost the same as that of the first embodiment shown in FIGS. Therefore, the tight frame 12, the gutter 13,
The reinforcing rod 14 is the same as in the first embodiment.

In FIG. 11, the fixing piece 24 of the tight frame 12 is brought into close contact with the upper surface of the H steel material 33, and the H steel material 33 is fixed by passing a screw through the screw hole 25. Therefore, many tight frames 12 are arranged in a grid pattern at equal intervals on the roof set of the house 1. Then, the long roof material 81 is attached to the roof 5 in the longitudinal direction.
The roof 5 can be roofed by arranging them in the direction of No. 1 and arranging a plurality of them in parallel in the lateral direction. In this case, each roofing material 81 is arranged between the tight frames 12,
The L-shaped rising portions 85 on both sides are brought into close contact with the side surfaces of the T-shaped portion 26. After that, the internal space of the caulking body 86 is inserted from the mounting portion 27 of the T-shaped portion 26, the mounting portion 27 and the top of the rising portion 85 are wrapped in the caulking body 86, and caulking is performed from the outside of the caulking body 86 to make it tight. The frame 12, the roof material 81, and the caulking body 86 are fixed.

Also in this fifth embodiment, as shown in FIGS.
The heat generated inside the house 1 is applied to the roofing material 8 as in the case of
The bottom surface of No. 1 can flow and melt the snow accumulated on the roof material 81. In this structure, the roof material 81 and the caulking body 86
Can be configured by a separate member, and after the roof material 81 is arranged between the tight frames 12, the caulking body 86 is attached to the roof material 8.
Since it can be combined with 1, the work can be performed quickly.

As described above , according to the present invention, it is possible to assemble a plurality of metal roof members side by side with a roof assembly of a house with a simple structure. In assembly of the roof member, the roof member side by side at
All that is required is to caulk the parts and connect them to the tight frame, which shortens the roofing process. In addition, since each roof member has a large surface area because it is bent in a wavy shape and has a high heat exchange rate, it is effective for melting snow. Further, since the cross-sectional shape is an arcuate mountain shape, the durability to support snow accumulated is improved, and the load bearing capacity can be increased as compared with a flat roof structure.
