That is, when water such as rain flows on the roof 24, it flows from the mountain fold 32 of the folded plate 30 to the valley fold 36, and travels along the slope of the roof 24 from the flat surface 38 of the valley fold 36. 36 drains 48. And, as shown in FIG. 2, the pipe 50 connected to the drain port 48 is drained to the lower side of the store 10 through the indoor pipe 78.

  Further, as shown in FIG. 2, a snow stop device 52 is provided on the upper surface side of the roof 24 on the lower side 42 of the inclined surface on the back surface 22 side of the roof 24. This snow stop device 52 is provided with a snow stop plate 54, and a wedge-shaped space 56 sandwiched between the snow stop plate 54 and the roof 24 is formed below the snow stop plate 54.

  The snow stop plate 54 is configured by the folded plate 30 similarly to the roof 24 and is formed in an elongated plate shape (see FIG. 1). The length of the snow stop plate 54 in the long side direction is substantially the same as the length of the roof 24 in the width direction. In addition, the length in the short side direction can be appropriately changed. In the present embodiment, the length in the depth direction of the roof 24 is about 1/3 to 1/4. Furthermore, a nose cover panel 26 is provided along the long side direction at the terminal on the back surface 22 side of the snow stop plate 54. That is, the dimension of the long side of the nose cover panel 26 is substantially the same as the length of the snow stop plate 54 in the long side direction. The dimension of the short side of the nose cover panel 26 is set to be slightly larger than the dimension in the vertical direction of the flat surface 34 of the mountain fold portion 32 and the flat surface 38 of the valley fold portion 36 of the folded plate 30. Furthermore, it fixes so that the lower edge part of the nose cover panel 44 and the back surface of the snow stop board 54 may align with the fastening member etc. which are not shown in figure. As a result, the terminal on the back surface 22 side of the snow stop plate 54 is covered with the nose cover panel 44.

  The snow stop plate 54 is inclined in the direction opposite to the inclination direction of the roof 24. In the present embodiment, the inclination angle of the snow retaining plate 54 is equal to the inclination angle of the roof 24 with respect to the horizontal, and is preferably set at this angle, but is not limited to this and exceeds the horizontal. It may be set within a range of angles less than vertical.

  Further, a leg portion 58 is provided below the snow stop plate 54 along the long side portion of the snow stop plate 54, and the leg portion 58 includes the first leg portion 80, the second leg portion 82, and the like. It consists of The first leg 80 and the second leg 82 have different leg lengths, and the leg of the second leg 82 is set longer than the leg of the first leg 80. Further, the first leg portion 80 and the second leg portion 82 are respectively attached in one of the vertical directions to a mounting surface 60 parallel to the inclination of the snow stop plate 54 and to the other side in parallel to the inclination of the roof 24. A surface 62 is provided. The lower surface side of the flat surface 38 of the snow stop plate 54 and the mounting surface 60 are fixed by a fastening member such as a bolt (not shown). Similarly, the upper surface side of the flat surface 34 of the roof 24 and the mounting surface 62 are not shown. It is fixed with a fastening member.

  The cross-sectional shape of the second leg portion 82 shown in FIG. 2 is from the inner side surface of the outer wall panel 14 of the one side surface 20 of the store 10 along the long side portion of the snow stop plate 54 to the outer wall panel 14 of the other side surface 20. It is made into the shape which continued to the inner surface in. As a result, the back surface 22 side of the space 56 is substantially blocked, and it is difficult for wind and snow to enter the space 56 from the outside.

  The snow stop plate 54 is provided with a snow stop fitting 64 on the flat surface 34 of the mountain fold 32. As an example, the snow stop fitting 64 is made of a metal having a substantially L-shaped cross section, and is fixed to the snow stop plate 54 by a fastening member such as a bolt (not shown).

  Inside the store 10, a cooking chamber 66 is provided for cooking and processing foods provided as commodities. As an example, the cooking chamber 66 is provided with a cooking table 68 provided with a cooking device for heating and heating such as a hot plate and an electric fryer. A ventilation fan 70 and an exhaust duct 72 as exhaust means connected to the ventilation fan 70 are provided from the cooking chamber 66 to the space 56 at the upper portion of the cooking table 68.

It is connected to a discharge port (not shown). For example, the exhaust duct 72 is made of a material having high thermal conductivity such as metal. In addition, although the cross-sectional shape of the exhaust duct 72 is circular in this embodiment, other shapes, such as a substantially square shape, may be sufficient.

(Action / Effect)
Next, the operation and effect of this embodiment will be described.

  As shown in FIG. 3, when snow 74 falls on the store 10, snow 74 </ b> A and snow 74 </ b> B accumulate on the roof 24 and the snow stop plate 54, respectively. The snow 74 </ b> A that has accumulated on the roof 24 tends to flow toward the back surface 22 side of the store 10 along the inclination of the roof 24. Separately, the snow 74 </ b> B accumulated on the snow stop plate 54 tends to flow toward the front side 28 of the store 10 along the inclination of the snow stop plate 54. Therefore, the snow 74A is blocked by the snow stop plate 54 and the snow 74B. As a result, since the snow 74A on the roof 24 is retained on the roof 24, the snow 74A does not fall from the roof 24 to the ground. Further, since the snow stop plate 54 is inclined to the front 28 side and the snow stop fitting 64 is provided, the snow 74B on the snow stop plate 54 is transferred from the snow stop plate 54 to the ground. There is no snowfall.

  In the indoor cooking chamber 66, hot air 76 is generated by heating cooking such as fried food on the cooking table 68. The hot air 76 is sucked by the ventilation fan 70, passes through the exhaust duct 72 connected to the ventilation fan 70, and is discharged to the outside. At this time, the heat of the hot air 76 passed through the exhaust duct 72 is radiated outward from the exhaust duct 72 itself. Thereby, the air in the space 56 is warmed, and the snow retaining plate 54 is also warmed accordingly.

  When the snow stop plate 54 is warmed, the snow 74B accumulated on the snow stop plate 54 is melted to become water, and is flowed to the front 28 side of the store 10 along the inclination of the snow stop plate 54. From 54 to the roof 24. Then, the water that has flowed down is caused to flow along the slope of the roof 24 along the flat surface 38 of the valley fold 36 toward the back surface 22 of the store 10, and from the drain port 48 provided on the flat surface 38 of the valley fold 36. It is drained to the lower part of the store 10 through the collective piping 78 passing through the room.

  At this time, the snow stop water flows from the snow stop plate 54 to the roof 24, so that the snow 74A accumulated on the roof 24 is melted. Thereby, the snow 74 </ b> A on the roof 24 becomes water and flows downward along the flat surface 38 of the valley fold 36 of the roof 24, and is drained from the drain port 48 to the lower part of the store 10. Accordingly, the snow 74 accumulated on the roof 24 and the snow stop plate 54 can be processed without being dropped from the roof 24.

  In addition, during the rain, rainwater that has fallen on the roof 24 flows from the mountain fold portion 32 of the roof 24 to the plane 38 of the valley fold portion 36 and flows toward the back surface 22 side of the store 10 along the inclination of the roof 24. It is. Then, the water that has flowed down is drained from the drain port 48 provided in the valley fold 36 through the pipe 50 through the collective pipe 78 passing through the room to the lower part of the store 10. Similarly, rainwater that has fallen on the snow stop plate 54 flows on the roof 24 along the inclination of the snow stop plate 54, and is drained from the drain port 48 along the inclination of the roof 24. Furthermore, when the amount of rain exceeds the processing capacity drained from the drain port 48, the overflowed rainwater flows to the end of the roof 24 and is discharged from the gap 46 to the outside.

  As described above, on the lower side of the inclined surface of the single-flow roof 24 provided in the building, the inclination direction is opposite to the inclination direction of the single-flow roof 24 and the inclination angle is greater than horizontal and less than vertical. A snow stop plate 54 is provided. Therefore, even when the snow 74 </ b> A accumulated on the roof 24 moves down along the slope of the one-flow roof 24, the snow 74 </ b> A is blocked by the snow stop plate 54 provided on the lower side in the slope direction of the roof 24. It is possible to stay on the roof 24 and prevent snow from falling on the ground. Thereby, even in a single-flow roof, the construction period is short, and it is possible to obtain a snow-free roof structure that can suppress costs.

  Further, the single-flow roof 24 is a folded-plate roof composed of folded plates 30, and a drainage port 48 is formed in each valley fold 36, and the drainage port 48 has a pipe 50 as a communication path. It is connected to one collective piping 78 which passes indoors through. Therefore, the water flowing on the roof 24 flows from the mountain folded portion 32 of the folded plate 30 to the valley folded portion 36, and the water in the valley folded portion 36 flows downward along the inclination of the roof 24. Then, the water that has flowed down can be drained indoors by a single collecting pipe 78 connected through a pipe 50 as a communication path from a drain port 48 provided in the valley fold 36. It becomes. That is, the water on the roof can be efficiently treated by the drainage port 48 formed by processing the valley fold 36. As a result, water on the roof 24 is received by the collecting pipe 78 through the drain port 48 provided in the valley fold 36, so that the dredging becomes unnecessary and the dredging of the dredging can be prevented from occurring. it can.

  Further, an exhaust duct 72 is provided between the snow stop plate 54 and the roof 24 as exhaust means for discharging indoor air to the outside. Accordingly, the indoor warm air is dissipated when passing through the exhaust means, so that the snow stop plate 54 is warmed, whereby the snow 74B accumulated on the snow stop plate 54 is melted and becomes water. Then, the water flows along the slope of the snow stop plate 54 and is received on the single-flow roof 24, and then flows along the inclination of the single-flow roof 24 to the drain port 48 provided in the valley fold 36. And is discharged indoors through the bottom of the building. Further, when the melted snow flowing on the snow stop plate 54 flows to the roof 24, the snow 74 </ b> A on the roof 24 is also melted and flowed to the drain outlet 48. As a result, the snow 74 accumulated on the roof 24 can be processed without being dropped from the roof 24. Thereby, it becomes possible to prevent the snow 74 accumulated on the roof 24 from falling to the ground.

  Furthermore, the snow stop plate 54 formed in the shape of an elongated plate is provided with a first leg portion 80 below one long side portion of the snow stop plate 54. Further, a second leg portion 82 having a leg length longer than that of the first leg portion 80 is provided below the other long side portion of the snow stop plate 54. Therefore, the snow stop device 52 having the snow stop plate 54 inclined in the direction opposite to the inclination direction of the attached roof 24 by the legs 58 having different heights is formed on the roof 24 of the building at the time of new construction or renovation. Attached to. As a result, even if the snow 74 accumulated on the roof 24 flows down along the slope of the single-flow roof 24, the snow 74 is provided on the roof 24 by the snow stop plate 54 provided on the lower side of the roof 24. It is possible to prevent the snow from falling on the ground. That is, a snow-free structure can be obtained without greatly changing the roof 24. Thereby, cost can be suppressed. Furthermore, it can be easily attached to the roof of an already built building.

  On the other hand, in a conventional snow-free roof, a trough is provided in the center of the roof, and a trough-shaped slope is attached to the trough toward the trough. Thereby, the snow piled up on the roof is melted by sunlight or the like, and is flown to the valley, and is caused to flow from the valley to the lower part of the building, thereby preventing snowfall from the roof. Therefore, it is necessary to construct a waterproof sheet at the joint between the roof and the valley as a countermeasure against leakage due to freezing of the valley located at the center of the roof. Furthermore, when adopting a snow-free structure for a single-flow roof, a snow duct or other fence is provided at the lower end of the slope of the roof, but there is a possibility that leakage from between the fence and the roof may occur. Therefore, it is necessary to lay a waterproof sheet or the like as described above. However, since the construction of the waterproof sheet or the like requires work on site, the construction period becomes long. Furthermore, in the case of a roof composed of folded plates, the construction of the waterproof sheet is inevitably complicated due to the sectional shape of the folded plates. For this reason, the construction period becomes long, and the cost cannot be suppressed.

  However, according to the present embodiment, the snow stop plate 54 composed of the folded plate 30 similar to the roof 24 is installed on the roof 24 with an inclination opposite to the inclination direction of the roof 24, and the roof 24 and the snow stop plate are installed. 54 is provided with an exhaust duct 72 as exhaust means. As a result, the snow stop plate 54 is warmed by heat from the exhaust duct 72, and the snow melted on the snow stop plate 54 becomes water and does not stay along the slope of the snow stop plate 54, but onto the roof 24. Washed away. The flowing water flows along the slope of the roof 24 to the drain port 48 installed in the space 56 warmed by heat radiation from the exhaust duct 72 and is drained through the room. This allows the snow 74 to be processed without dropping from the roof 24. Moreover, since the collective piping 78 passes indoors, it does not freeze. Further, since the snow does not accumulate on the drain port 48, the drain port 48 is not blocked, and the pipe 50 is not frozen and water is not retained on the roof 24. For this reason, it is possible to prevent leakage or the like without performing construction of a waterproof sheet or the like.

  Further, the snow stop device 52 has a simple structure including the snow stop plate 54 and the leg portion 58, and the drain 24, the pipe 50, the collective pipe 78, and the exhaust duct 72 are only provided on the roof 24 on the installation side. It becomes possible to make it a snow-free roof. That is, since a fence such as a snow duct is provided in the center of the roof 24, it is not necessary to make a major change such as making the roof into a valley shape. Therefore, even when the roof 24 is a roof manufactured in a factory by a unit method, the drainage port 48, the pipe 50, the collective pipe 78, and the exhaust duct 72 are provided by post-processing while maintaining the current roof structure, By installing the snow stop device 52, a snow-free roof can be obtained. For this reason, it is not necessary to change the design of the unit, and work on site such as laying a waterproof sheet or the like becomes unnecessary. For this reason, a construction period (time) is shortened and it becomes possible to suppress cost.

  Further, in a commercial facility or the like that requires a small number of columns such as the store 10, a single-flow roof composed of the folded plates 30 is employed. Even in this case, the snow stop device 52 is installed on the roof 24, and the roof 24 is provided with the drain port 48, the pipe 50, the collective pipe 78, and the exhaust duct 72. . Thereby, construction of the waterproof sheet in the junction part with the ridge which becomes complicated by the cross-sectional shape which becomes the repetition of the mountain fold part 32 and the valley fold part 36 of the folded plate 30 becomes unnecessary. For this reason, it becomes possible to shorten a construction period (time), suppress cost, and make it a snow-free roof.

  In the snow-free roof structure of the present embodiment, the roof 24 is provided with a drain port 48, a pipe 50, a collective pipe 78, and an exhaust duct 72, and the snow stop device 52 is installed on the roof 24 to realize snow-free snowfall. Since it can be configured, it can be easily installed on the roof of a building that has already been constructed. For this reason, it becomes possible to shorten a construction period (time), suppress cost, and make it a snow-free roof.

  In the present embodiment, the snow stop fitting 64 is provided on the flat surface 34 of the snow stop plate 54. However, when the inclination of the snow stop plate 54 is set to an angle close to vertical, the snow stop fitting 64 is provided. It is good also as a structure without.

  Further, the leg portion 58 provided between the snow stop plate 54 and the roof 24 is not limited to a separate member, and the snow stop plate 54 may be folded downward to form the leg portion 58. Further, the lower edge portion of the nose cover panel 26 provided on the snow stop plate 54 may be extended and fixed to the roof 24. Furthermore, the snow stop plate 54 may be fixed by extending the upper edge of the nose cover panel 44 provided on the roof 24.

  Further, the terminal on the back surface 22 side of the roof 24 is configured such that a gap 46 is provided in the lower part of the nose cover panel 44. However, the present invention is not limited to this, and the nose cover panel 44 provided so as to cover the entire terminal. It is good also as a structure by which one or several hole is provided in the lower side.

  The embodiment of the present invention has been described above, but the present invention is not limited to the above, and various modifications other than those described above can be implemented without departing from the spirit of the present invention. Of course.
