Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Field of Application) The present invention relates to a method for melting snow on a roof, in particular, to a method for melting snow on a roof, in particular, a method for melting snow on a roof. This paper relates to a method for melting snow on roofs using a method of guiding snow to the back side of the board body.

(Prior art) Conventionally, as a roof snow melting method for this scale, warm air introduced into the air outlet on the eaves side passes through the spaces between the supporting parts of multiple roofing materials and the space within the supporting parts to warm the m-board materials. It's like that lζ
This is known from Japanese Unexamined Utility Model Publication No. 11f155-109748.

(Problem to be Solved by the Invention) However, this is because the hot air introduced into the air outlet on the eaves side flows all at once toward the space from the opening formed almost entirely on the eaves, causing the roof metal to reach the roof surface. As a result, the flow of warm air is weak and uneven, resulting in the snow on the roof only being partially melted.

[Structure 1 of the Invention (Means for Solving the Problems) Warm air introduced into a duct having a substantially gate-shaped cross section through a warm air flow path on the eaves side is connected to a plurality of substantially bar-shaped ducts communicating with the ducts 1 to 1. It passes through the shaped field rafters and is guided almost uniformly over the entire roof surface, and then flows out from the vents formed in the side walls of the field rafters and fills the back surface of the roof board body. This is what I did.

(Example) An example of the present invention will be described below with reference to the accompanying drawings.

1 to 5 show a first embodiment, in which 1
are rafters that extend from the eaves toward the ridge, and roof boards 2 are installed on top of these rafters. Reference numeral 3 denotes a warm air flow path formed in communication with the indoor room 4 in the direction of the main house at the lower part of the eaves side, and ducts 1 to 5 having a substantially gate-shaped cross section made of chemical materials such as metal or plastic are provided at the upper end of the path. .

Reference numeral 6 denotes field rafters having a substantially gate-shaped cross section made of chemical materials such as metal or plastic and provided in large numbers at intervals from the eaves to the ridge on the field board 2, and the field rafters 6 and the ducts 1- 5 communicates with the ventilation lowers provided on both side walls of the duct 5. The outdoor rafter 6 has flanges 6A at the lower ends of both side walls, and a large number of elongated ventilation holes 9 for guiding warm air to the back surface of the roof board body 8 are provided on the upper slope portions 6B of both side walls. This roof plate main body 8 has a horizontal portion 8A and an inclined portion 8B, like the face plate known from, for example, Japanese Utility Model Application Publication No. 15522/1983. A ventilation path 10 is formed between the outdoor rafters 6, and a space 11 is formed on the back side of the sloped portion 8B of the roof board body 8 in a direction crossing the outdoor rafters 6. The roof board main body 8 is fastened to the field rafters 6 by a fixing device (not shown), and
The 7-lunge 6A is fixed to the shedding board 2 by a fixing device (not shown). Reference numeral 12 denotes a cavity formed in the roof top portion 13, which communicates with the ventilation path 10. Reference numeral 14 denotes a vent hole formed in the roof top portion 13, which communicates the cavity 12 with the outside air. The warm air of daily heat energy generated by heating heat in the room 4 is naturally introduced from the hot air flow path 3 into the duct 5 which has a generally gate-shaped cross section, and then passes through the ventilation lower into the field rafters 6 which have a gate-shaped cross section. and is guided almost evenly over almost the entire roof surface. Thereafter, it flows out into the ventilation path 10 from the many ventilation holes 9 provided on both side walls of the field rafter 6, fills the back surface of the roof board body 8, and flows toward the ridge, passing through the cavity 12 of the roof top 13. and flows out from the vent 14 to the outdoors. In this way, the warm air introduced from the warm air flow path 3 is guided from the duct 1-5, which has a gate-shaped cross section, to the field rafters 6, twisted and twisted over almost the entire roof surface, and flows out from the vent 9. Since the warm air is filled so as to cover the back surface of the roof board body 8, it becomes possible to wrap the entire roof surface with warm air and warm it, and natural snow melting and natural lightning strikes can be carried out effectively. Also duct 5
The formation of icicles is prevented by warm air flowing out to the eaves side from the ventilation lower of the side wall. 1. The shape of the field rafter 6 may be a substantially gate-shaped structure such as the structure shown in FIG. 5 without the slope part 8B.

FIG. 6 shows a second sub-example, which will be described using the same reference numerals for the same parts as in the above embodiment. Furthermore, explanations of the same parts as in the above embodiment will be omitted.

Warm air in the room 4 naturally enters through the ceiling opening 3A, passes through the duct 3B installed in the attic, is guided to the warm air passage 3 at the eaves, and is introduced into the duct 5, which has a generally gate-shaped cross section, and then passes through the ventilation lower. It flows into a large number of field rafters 6 having a gate-shaped cross section and is guided over almost the entire roof surface, flows out into the ventilation path 10 from the ventilation holes 9 on both side walls of the field rafters 6, and flows into the roof board body. It fills up so as to cover the back surface of the roof 8, flows toward the ridge, is led to the ceiling through the opening 15, and flows out from the louver 1G to the outdoors, thereby obtaining the same effect as in the above embodiment.

FIG. 7 shows a third embodiment, in which the same parts as in the above embodiment are denoted by the same reference numerals.A blow pipe 19 is connected to a hot air generator 17 and a pump 18 in a warm air passage 3 formed on the side of the eaves. By connecting these, hot air can be forcibly blown into the heating flow path 3 through the air blower vibrator 19 during heavy snowfall, severe cold, or at night, making it possible to quickly melt snow. In this case, the hot air may be circulated from the ridge side using a blower vibrator (not shown).

Fig. 8 shows the fourth practical example, in which the same parts as in the above embodiment are given the same reference numerals.This is an air circulation system for the whole building using the snow melting method described above, and the winter season is represented by a dashed line. The heated air from the louver 20 is introduced into the hot air passage 3 from the opening in the ceiling, passes through the ducts 1-5 and the field rafters 6, and then flows from the vent 9 into the ventilation passage 1.
The snow flows into the interior of the roof, fills the back surface of the roof board 8, flows out from the vent 14 outside, and melts the snow. In the summer, as shown by the solid line, the warm air is introduced from the ventilation opening 21 through the hollow passage 23 of the wall 22 into the ventilation passage 3, passing through the duct 5 and the field rafters 6 in the same way as above, and then flowing into the ventilation passage 10. It flows out to the outside from the ventilation hole 14. This effectively prevents air pollution and condensation in the winter, and evaporates and prevents condensation in the summer.

Note that the present invention is not limited to the above embodiments,
Various modifications are possible within the scope of the invention.

For example, a base material or a heat insulating material may be provided on the upper surface of the shedding board, and instead of a hot air generator, piping may be used to utilize residual heat from a heating device, gas stove, water strainer, bath, etc., or exhaust heat. Further, in the first embodiment, the structure may be selected as appropriate, such as using the roof plate main body 8 having the sloped portion 8B and using the roof plate main body having a horizontal structure as a whole. In addition, in the case of the second embodiment shown in FIG.
A suction fan may be provided in the section to draw warm air outdoors.

[Effects of the Invention] The present invention allows warm air introduced into a hot air flow path on the eaves side to be guided over substantially the entire roof surface through a duct with a substantially gate-shaped cross section that communicates with the field rafters, and to pass through the field rafters. The warm air that flows out of the pores fills the roof to cover it, resulting in better overall natural snow melting and natural lightning strikes, which is highly effective.
