Description

      The present invention features a structure that can be attached to and detached from an existing roof, makes the best use of the principles of nature, makes it simple structure, light weight, easy to attach and detach, low cost, good landscape, and does not depend on heat sources, human power, etc. In practice, if the snow piles up on the roof during winter, it is not intended to drop this snow, but if the snow falls between 20Cm and 30Cm, it will slide down without snow on the roof. It is a device aimed at.

    Although there is a snow treatment that pumps up groundwater and sprinkles water as in Patent Document 1, there is a concern that ground subsidence will be caused by pumping up groundwater.

    The construction of a new steep roof requires a great deal of money, and it is life threatening to remove snow manually. The snow cover prevention apparatus shown in Utility Model Document 1 shows a method of covering a steeply inclined frame with a sheet, but the structure and the assembly method are not realistic. Not only is it effective, but the structure must be simple, easy to install, light in weight and landscaped.

    According to Patent Document 2, Patent Document 3, and Utility Model Document 2, a sheet is rotated as a snow removal device, a long brush is moved, a C-type snow stop plate is attached to a belt conveyor, and the snow is lowered by rotating. Although the methods are shown, both are pros and cons, the apparatus is generally precise and complex, and the equipment costs, maintenance, freezing of the rotating parts due to snow, etc., rather use nerves.

      Every winter, especially the treatment of snow on the roof, imposes a great mental and economic burden on each household and local government. There is also a risk of human life. The snow quality varies greatly depending on the region, the snowfall method varies depending on the climate, location conditions such as in the city or in the mountains, and measures against snow, and devices that apply prior art etc. are also pros and cons and are not popular. In the present situation, when the snow has accumulated 50 Cm to 100 Cm, the main purpose is not to drop this snow, but it is intended to slide down without snow on the roof even if it falls 20 Cm to 30 Cm. Therefore, there is a demand for reduction of large equipment costs, heat source costs and human labor. The present invention proposes an apparatus that attempts to solve the above problems.

      The present invention is an automatic snowfall type snow lowering device that can be attached to and detached from an existing roof, and is fixed to the base member 1 and the base member 1 to be attached to and detached from the roof. The basic frame 2 and the large snow split frame 3 at the center of the roof fixed to the base member 1, and the snow slide surface structures 4 a and 4 b mounted on the basic frame 2 and the snow split frame 3. The snow split frame 3 in the center of the roof that promotes natural snowfall is formed at an inclination angle of 50 ° to 55 °, and the inclination angle of the basic frame 2 that receives snow from the snow split frame 3 is 45 ° to 50 °. And a snow sliding surface structure 4a, 4b is fitted into the snow split part frame 3 and the basic frame 2 of the part that receives the snow fall.

      Many of the snowfall type prior arts have complicated structures and are too precise, and probably have too much equipment and maintenance costs. In the present invention, the structure of a snow sliding surface that can be attached to and detached from an existing roof, is simple in structure, lightweight, inexpensive, and has a snowfall effect that makes the most of the principle of nature and fits into the snow split frame 3 having a large angle at the center of the roof. In combination with the snow sliding surface structure 4b that fits in the basic frame 2 that naturally falls 30% of the snow in the body 4a and falls from the snow sliding surface structure 4a, the snow does not accumulate on the roof. It has the effect of not having to slide down and snow down on the roof.

      Hereinafter, embodiments will be described together with the illustrated examples. As shown in FIGS. 2 and 3, the base member 1 is provided with a plurality of sets having a spacing of 100 Cm inward with two iron angles on both slopes of the roof. The two iron angles are welded in a ladder shape to a position where the leg scaffolding portion of the center snow split portion frame 3 and the leg portion of the basic framework 2 located below the center are received. Ladder-shaped angles on both roof slopes are connected and fixed with bolts to an iron plate 1c placed so as to straddle the top of the roof. This ladder-shaped angle is the size of the roof and connects several units side by side with bolts. A rubber mat 1d is laid under the iron plate 1c and a portion welded in a ladder shape to protect the roof. The protective rubber mat 1d may be a vinyl mat. The entire base member 1 is fixed at the eaves of the roof and the edge of the roof so that it does not move.

      As shown in FIGS. 4 and 5, the basic frame 2 and the center snow split frame 3 are installed at a width interval of 100 Cm. Both frames 2 and 3 use 30 mmφ iron pipes or 45 mmφ Envi pipes. The inclination angle of the snow split frame 3 is 50 ° to 55 °, the inclination angle of the lower basic framework 2 is 45 ° to 50 °, and the leg of the frame is the ladder portion of the base member 1 made of iron angle material. It fixes to the scaffold parts 1a and 1b. As shown in FIG. 6, joint members 2a, 2b and 3a, 3b for fitting the snow sliding surface constituting bodies 4a, 4b are mounted.

      The material used for the snow sliding surface structures 4a and 4b to be fitted into the inclined portion has an important affinity with snow, and a polycarbonate type or a fluororesin type is suitable. However, the application of fluorine gas is also effective. The width of the snowslide surface structures 4a and 4b is 100 Cm and is framed by an aluminum material, and the snowslip surface structure 4a of the snow split portion having a large inclination angle is formed on an aluminum material frame with a reinforcing curing mat 8 as shown in FIG. The air cap 9 and the reinforced polycarbonate plate 11 are assembled into an aluminum frame as a panel and attached to the snow split frame.

      Basically, the greater the angle of inclination of the skeleton, the easier it is for snow to fall. However, there is a risk of falling snow if the snow quality is very wet and the snow falls heavily. Therefore, an improved snow sliding surface structure is proposed in consideration of the above problems. In the lower snow slip surface constituent body 4b which receives the snow fall from the snow sliding surface constituent body 4a of the snow split part, the inclination angle is not so large as to fall naturally by 100%, so that there is snow on the panel surface of the snow slip surface constituent body 4b. It is assumed that The degree of snow accumulation depends on the snow quality with a lot of moisture and how snow falls in the region and weather conditions. As an example of the snow slide surface structure 4b, it is framed with an aluminum material having a width of 100 Cm and is provided at both ends. FIG. 8 shows an endless rotating sheet including a curing mat 8, an air cap 9, and a curing sheet 10.

      As an example of the snow sliding surface constituting body 4b, a tension spring 12 is placed on the upper part of the rotating body that is constructed of lightweight plastic rotating rollers 7a and 7b that are framed with an aluminum material having a width of 100 Cm and bearings at both ends. FIG. 9 proposes a mechanism for dropping snow by sliding the slide sheet (reinforced polynate plate) 11 with the compression spring 13 attached to the lower part thereof within the frame of the guide rail 14 with the weight of snow so as not to be laterally displaced.

      As an example of the snow slide structure 4b, a plastic plate is used instead of a sheet around the rotary body 7 which is framed by an aluminum material having a width of 100 Cm, has a rotary roller 7 at both ends, a gear 15 at one end, and a guide roller 21. A gear 15 incorporating a shutter-like or curtain-like endless rotating body 18 is manually geared 19 or a sensor 17 for detecting the weight of snow is incorporated and rotated by an electric motor 16 to forcibly remove snow on the panel. The one shown in FIG. 10 is proposed.

      As an example of snow removal, as a method used together with the present invention, a method of spraying warm water directly onto the roof of the house by spraying ground water directly onto the snow on the roof with a pump 6 can be considered. However, because of the problems of groundwater depletion, land subsidence, and the cost burden of electricity, gas, and kerosene, the water tank 5 is dug as shown in Fig. 1 at a depth of 3m to 3.5m under the house eaves. Rainwater is stored in the water without any heating even in the winter due to the geothermal effect, and this is sprinkled on the roof to assist in snowfall on the roof, and the snow falling from the roof is received in the aquarium. It also reduces the work of removing the snow that has melted and fallen.
