[Conventional technology]

As mentioned above, conventional snow-free roof structures allow snow accumulated on the roof to slide off. To prevent roof chilling, slope the roof surface from the eaves down toward the center of the roof. It is constructed with a slope of .

0003 The above roof structure is installed in the duct groove provided along the lowest part of the center of the roof. Passes warm air from inside the building and exhausts this warm air to the outside through holes in the perforated plate covering the duct grooves. This melts the snow that has accumulated on the roof. The melted snow water is on the roof surface. It flows down along the slope, flows down into the duct groove from the hole in the perforated plate, and comes into contact with the duct groove. The water is drained through a connected drainage pipe.

[Problem that the idea aims to solve]

The snow-free roof structure described above allows warm air inside the building to pass through the duct grooves and through the holes in the perforated plate. This system thaws snow on the roof by exhausting the air through the roof. however As mentioned above, the warm air passed through the duct groove is exhausted relatively quickly through the holes in the perforated plate. Because of this, the heat from the warm air cannot be used effectively to thaw the snow. .

[0005] Also, if the outside air temperature is very low, the cold air on the roof will overcome the warm air in the duct grooves. The water flows into the duct groove through the holes in the perforated plate, and is further connected to the duct groove. There was a possibility that it would flow into the pipes, freeze, and block the drain pipes.

[0006] The present invention is designed to melt the snow on the roof for the above-mentioned snow-shedding roof structure. By providing a means to effectively utilize the heat of warm air supplied into the duct groove. This improves the efficiency of thawing snow by warm air, and also prevents damage to the inside of duct grooves and drain pipes. The goal is to prevent cold air from flowing into the area.

[0007]

[Means to solve the problem]

In order to solve the above-mentioned problems, this invention has a downward slope from the eaves to the center of the roof. If the duct groove is recessed along the center of the roof, which is the lowest part, In addition, by covering the duct groove with a perforated plate, snow from the roof surface can be prevented from entering the duct groove. It functions as a drainage channel for melted water and at the same time as a ventilation channel for passing warm air from the room. In the snow-proof roof made of By installing a cap plate with a shape of In both cases, a small gap for drainage is provided between both side edges of the cap plate and the roof surface.

[0008]

[Effect]

According to the above means, the cap plate provided along the top of the perforated plate can be cooled from the outside. To prevent warm air from entering and at the same time retain warm air in a retention space without escaping to the outside. Therefore, the warm air flowing into the duct groove from inside the building passes through the holes in the perforated plate and into the cap plate. The warm air stays in the retention space formed between the cap plate and the cap plate. The snow on the roof surface is thawed through the cap plate.

[0009] Melted snow water on the roof flows down along the slope of the roof, and the water flows down the slope of the roof, and the water flows down to the edge of the cap plate on both sides and the roof. It flows into the duct groove through the small gap formed between the surface and the drainage path. The water will be drained.

[Effect of the idea]

As described above, the present invention is constructed by installing a cap board along the top of the perforated board. Because it retains warm air from the room in a retention space and uses that heat, Compared to the conventional method where warm air is directly exhausted, the heat of warm air is used more effectively. This can be used to efficiently thaw snow.

[0011] In addition, the cap plate allows warm air to stay in the retention space at all times, while at the same time keeping cold air from outside. It also prevents the infiltration of cold air from the outside and allows a large amount of cold air to flow into the duct groove. It is also possible to prevent the infiltration of

【Example】

Hereinafter, one implementation of the present invention will be described based on the drawings. FIG. 1 shows the central part of a roof in which the present invention has been implemented. The roof mentioned above is the roof surface a of a galvanized iron roof that slopes downward from the eaves to the center of the roof. 1. Also, in the roof structure described above, the center of the roof is the lowest point. However, a duct groove 1 is recessed in the center of this roof.

[0013] The duct groove 1 is formed along the center of the roof to have a substantially U-shaped cross section, and the opening on the top surface will be described later. In addition to covering the groove with a perforated plate 2, there are several holes at the bottom of the groove to drain melted snow and rainwater. Drain pipes 4 are connected at appropriate intervals.

[0014] In addition, in the middle part of the above-mentioned drain pipe, there is an air pipe (not shown) that supplies warm air inside the building. (without) are connected horizontally, and the warm air inside the building sent from this air pipe is sent to the drain pipe 4. The water rises and flows into the duct groove 1 described above.

[0015] The perforated plate 2 covering the duct groove 1 is bent into a rectangular cross-section according to the slope of both roof surfaces a1. Near the center, there is a duct groove that collects the melted snow that flows down along the roof surface a1. A large number of holes 2a are drilled into the duct groove 1, and a waterproof material (not shown) is inserted into the opening of the duct groove 1. It is fitted through.

[0016] In addition, the holes 2a of the perforated plate 2 described above allow water to rise inside the drain pipe 4 and flow into the duct groove 1. The warm air that enters flows out into the retention space 5 formed between the perforated plate 2 and the cap plate 3, which will be described later. There is also a function to

[0017] The band-shaped plate 3 installed along the upper part of the perforated plate 2 described above is a cap plate. hat Board 3 is a band-shaped board bent into a convex shape so that the cross section is approximately hat-shaped, and is roofed with corrugated iron. Attach and fix using the retaining plate 8 and short pipe 10 to the gap 7 of both roof surfaces a1. are doing.

[0018] The holding plate 8 that fixes the cap plate 3 is made by bending a band-shaped metal plate into the same shape as the cross section of the cap plate 3. The cap plate 3 is fixed to the back side of the cap plate 3 with screws 9 at predetermined intervals.

[0019] In addition, the short pipe 10 has a cut 10a that fits into the gap 7 on the roof surface a1 along the entire length of the pipe. A notched groove 10b is cut out across the tube, and the end of the holding plate 8 is inserted into the tube end surface. For example, every other gap is formed parallel to both roof surfaces a1. Attach to.

[0020] Each short pipe 10 has a cut 10a fitted in a position near the center of the gap 7. Then, tighten the tightening screw 10c passed through the pipe 10 horizontally, thereby tightening the gap 7. It is installed and fixed by sandwiching it.

Insert both ends of each retaining plate 8 attached to the child plate 3, thereby making the cap plate 3 porous. It is supported at the top of the plate 2. Further, the short pipes 10 described above are arranged at appropriate intervals along the seam 7. By installing it with the following in mind, it prevents the snow on the roof surface A1 from sliding down. It can also be used as a snow stopper.

[0022] The holes 2a of the perforated plate 2 are inserted between the cap plate 3 and the perforated plate 3 supported as described above. A retention space 5 is provided to retain the warm air passing through and rising. Between the root surface a1 and both side edges of the cap board 3, melted snow flows down along the roof surface a1. A small gap 6 is formed through which the perforated plate 3 passes.

[0023] According to the snow-free roof structure configured as described above, the drain pipe 4 rises from inside the building. The warm air that flows into the duct groove 1 flows out through the holes 2a of the perforated plate 2, but does not escape to the outside. It stays in the retention space 5 without moving. Then, as mentioned above, the temperature inside the retention space 5 is increased. The cap plate 3 is heated by the air, and the snow on the roof surface a1 is moved to the center via the cap plate 3. It is gradually thawed from the beginning.

[0024] The snow that has thawed on the roof surface a1 becomes melted snow and flows down the roof surface a1. , the porous holes pass through the small gap 6 formed between the side edge plates of the cap plate 3 and the roof surface a1. It flows into the duct groove 1 through the hole 2a of the plate 2, and then falls down the drain pipe 4 and is drained. Ru.

[0025] As mentioned above, warm air from inside the building is retained in the retention space 5 and the heat is utilized. According to The accumulated warm air can be effectively used to efficiently thaw snow.

[0026] In addition, the cap plate 3 has the same effect as that when the warm air is constantly retained in the retention space 5 as described above. Sometimes, it also prevents cold air from entering from outside, so the cold air from outside can outweigh the cold air. A large amount of cold air entered the duct groove 1 and the drain pipe 4, freezing and blocking the drain pipe 4. It is also possible to prevent such things.
