Description

  The present invention relates to an apparatus for removing a snow pit that can be formed on the eaves (outer edge) of a rooftop or the like formed of a snow-free roof or a parapet.

  In recent years, houses in snowy areas such as Hokkaido, Tohoku, and Hokuriku have long and narrow grooves called 樋 as shown in Fig. 18 in order to prevent the snow on the roof from falling on the road or next door. A snow-free roof is often employed, or a parapet is often provided on the outer edge of a horizontal flat roof as shown in FIG.

  The snow-free roof has a roof near the center of the roof, and by forming an inclined surface of the roof toward this roof, it melts snow on the roof without falling snow from the eaves, leading the snow-melt water to the roof and drainage pipe It is supposed to drain from.

  In addition, the parapet is formed to have a convex height of about 30 to 50 cm so as to surround the outer edge of the roof or terrace. In order to prevent snow from falling by accumulating snow on the roof surrounded by such a parapet. The snow melts on the roof and drains the snow melt from the drain pipe.

  However, the above-mentioned snow-falling roof and parapets have the effect of preventing the snow from falling and the effect of suppressing the formation of ice banks and ice pillars at the eaves, but there is a problem that snow can easily be formed. A snow leopard is a lump of snow formed on the eaves of the roof, and grows so as to protrude to the outside of the eaves under the influence of wind or the like. In particular, the eaves facing the east side are extremely dangerous because snow plows grow large and fall due to the cold winter wind in winter.

  Therefore, in the past, each time a snow ridge grown using a stick or the like was crushed to prevent an unexpected accident from occurring. On the other hand, as an invention for solving the above-mentioned problem of snow ridges, a heating wire is stretched around the top surface of the parapet or the roof, and heat is supplied from the heating wire so that the snow is melted so that no snow or snowfall occurs. An invention has been proposed (Patent Document 1).

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a snowfall removing device according to the present invention will be described with reference to the drawings. FIG. 1 is a view showing a state in which the snow plow removing apparatus 1A according to the first embodiment is installed on the outer edge 2 of the roof, and FIG. 2 is a side view seen from the direction of arrow A in FIG.

  As shown in FIG. 1, the snow ridge removing device 1 </ b> A according to the first embodiment is attached to an eaves 2 such as a rooftop where a snowfall roof or a parapet is formed, and a long snow melting flat plate portion 3 </ b> A, It is comprised from the gap formation support part 4A for supporting the snow melting flat plate part 3A so that the gap S may be formed in the eaves edge 2 of the roof.

  The snow-melting flat plate portion 3A is for melting a snow canopy formed on the outer edge portion of the roof, is formed into a long flat plate by aluminum or the like, and is fixed to the gap forming support portion 4A along its longitudinal direction. A fixing hole H is drilled. The surfaces 31 and 32 of the snow-melting flat plate portion 3A have a mat finish (matte). This is because when the snow melting flat plate portion 3A is formed by extrusion molding, streaks in the extruding direction remain on the surface, and this causes a fine step due to the streaks to attach snow, thereby preventing this. It is. The material used for the snow melting flat plate portion 3A is preferably aluminum from the viewpoint of a material excellent in thermal conductivity, high strength, workability and corrosion resistance, but is not limited to this, and depends on use conditions. You may select suitably.

  As shown in FIGS. 1 and 2, the gap forming support portion 4A has a substantially L-shaped cross section, and has a gap S through which warm air passes between the outer edge portion 2 of the roof and the snow melting flat plate portion 3A. It is formed to support the snow melting flat plate portion 3A. A fixing hole H for fixing to the surface 32 on the roof side of the snow melting flat plate portion 3A is drilled in the tip end portion 41 of the gap forming support portion 4A. A fixing hole H for fixing to the eaves edge 2 of the roof is drilled in the base end portion 42 of the gap forming support portion 4A. 4 A of gap formation support parts should just be able to support the snow-melting flat plate part 3A so that the predetermined gap S may be formed, but it is preferable to use a plurality in consideration of the snow weight. However, if the number of the gap forming support portions 4A is increased or the width is excessively increased in order to obtain a safety factor of strength more than necessary, the gap S may be narrowed and the warm air passage may be insufficient. Because there is, attention is necessary.

  In the first embodiment, the snow melting flat plate portion 3A and the gap forming support portion 4A are fixed by tightening a nut to a screw communicated with the fixing hole H. However, the present invention is not limited to this. An adhesive or a clip member may be used. Further, in the first embodiment, the gap forming support portion 4A is formed separately from the snow melting flat plate portion 3A, but both may be formed integrally.

  Next, an installation method and an operation of the snow plow removing apparatus 1A according to the first embodiment having such a configuration will be described.

  First, when using the snow plow removing apparatus 1A according to the first embodiment, the front end portion 41 of the gap forming support portion 4A is fixed to the fixing hole H of the snow melting flat plate portion 3A, and the base of the gap forming support portion 4A is fixed. The end 42 is fixed to the outer edge 2 of the roof (including the parapet). Thereby, the snow melting flat plate portion 3A is arranged along the outer edge portion 2 of the roof in the longitudinal direction, and is supported in a state where the predetermined gap S is separated from the outer edge portion 2 of the roof, thereby providing a space through which warm air passes. It is like that. Further, the vertical direction of the snow melting flat plate portion 3A is fixed with the vertical direction substantially directed.

  As described above, after installing the snow plow removing apparatus 1A according to the first embodiment on the eaves 2, when snow accumulates on the roof and the snow plow 5 starts growing on the eaves 2, as shown in FIG. The snow canopy 5 covers the gap S of the snow melting flat plate portion 3A. However, a space due to the gap S is opened below the snow plow 5, and waste heat released from the outer wall surface of the building and air that is heated and raised by the exhaust from the ventilation port stay. Alternatively, even after the snowfall has completely grown, the wall is warmed by solar heat and the warm air rises and is guided through the gap S to the lower space of the snowfall 5.

  As a result, the warm air staying in the space of the gap S directly warms and melts the snow leopard, and melts the snow leopard 5 that has started to grow indirectly through the snow melting flat plate portion 3A having high thermal conductivity. This prevents the snow leopard 5 from growing greatly. Further, as shown in FIG. 4 (a), even if strong snow is strong and a large snow ridge 5 is formed in a short period of time, the warm air staying in the space and the snow melting flat plate portion 3A warmed by the air are sunk. 5 will be melted and cut. And the snow-melting flat plate part 3A fixed in a substantially vertical direction plays a role like a cutter, and as shown in FIG. 4B, the overhanging snow canopy 5 can be cut off. Further, when the snowmelt flat plate portion 3A is swung by the wind, the snowfall 5 is vibrated, so that the snowfall 5 is more easily removed.

  Further, if there is a record heavy snow or the like, it is considered that the snow canopy 5 grows so as to involve the snow-melting flat plate portion 3A and also closes the lower opening of the gap S. In this case, the warm air is not introduced into the gap S, and the above-described snow plow removal effect may be reduced. Therefore, assuming such heavy snow, a long electric heater (not shown) may be attached along the longitudinal direction of the snow melting flat plate portion 3A. As a result, even when the gap S is blocked by heavy snow, the temperature of the snow melting flat plate portion 3A can be positively increased, so it is easy to melt the base end portion of the snow canopy 5 and apply a slight force. It is designed to make it easy to cut. In addition, a tape heater etc. are mentioned as an electrothermal body.

  In the first embodiment, the gap S between the snow melting flat plate portion 3A and the gap forming support portion 4A is set to about 30 mm to 50 mm. If the gap S is set too narrow, the amount of warm air that remains is reduced, and the above-described snow melting effect may not be sufficiently exhibited. On the other hand, if the gap S is set too wide, the warm air is likely to be cooled and the efficiency is deteriorated, and there is a room for the snow ridge to grow up to the snow melting flat plate portion 3A. There is also a problem that the torque load applied to the base end portion 42 of the gap forming support portion 4A is increased.

  Moreover, in this 1st Embodiment, although the up-down direction of the snow-melting flat plate part 3A is made to correspond substantially to a perpendicular direction, it is not restricted to this, If it is in the range which has the cutter effect mentioned above, the eaves tip It may be inclined at an appropriate angle in accordance with the shape of 2. For example, as shown in FIG. 5, if the upper part of the snow-melting flat plate portion 3A is inclined outward along the longitudinal direction, the snow that accumulates on the inclined surface is blown off by the action of wind blowing along the roof, etc. There is a possibility that an effect of suppressing the growth can be obtained. However, it is necessary to be careful because if it is inclined too much, it will snow on the snow melting flat plate portion 3A. On the other hand, if the upper part of the snow-melting flat plate portion 3A is inclined inward along the longitudinal direction, it is in a state against the wind flow along the roof, and there is a high possibility that snow will adhere to the inclined surface.

  According to the first embodiment as described above, in order to suppress the growth of the snow pail 5 in advance and to easily cut off the formed snow pail 5 to prevent excessive growth, the snow pail 5 falls. Can prevent accidents caused by accidents. In addition, the snow leopard removing device 1A can be installed at the eaves 2 by simple repair work. After the installation, the snow leopard 5 is removed simply by leaving it alone, so that the initial cost is kept low and the running cost is unnecessary.

  Next, a second embodiment of the snow plow removing apparatus according to the present invention will be described with reference to the drawings.

Note that, in the second embodiment, the same or corresponding components as those of the first embodiment described above are denoted by the same reference numerals and the description thereof is omitted.

  As shown in FIGS. 6 and 7, the feature of the snow hoe removing apparatus 1 </ b> B of the second embodiment is that the reinforcing support 43 is suspended from the lower surface of the gap forming support 4 </ b> B. Then, by attaching the gap forming support portion 4B so that the reinforcing support portion 43 is in contact with the end surface of the outer edge portion 2 of the roof, it resists the load from the snow melting flat plate portion 3A, the snow plow 5 and the like, and wobbles after the attachment. It comes to prevent. In the second embodiment, the reinforcing support portion 43 is suspended. However, the reinforcing support portion 43 may be inclined with respect to the gap forming support portion 4B as long as it is within a range in which a reinforcing effect is exhibited.

Specifically, as shown in FIG. 9A, a pair of left and right slits 33, 33 extending from the bottom to the middle is formed in the vertical direction of the snow melting flat plate portion 3C, and formed between the slits 33, 33. The plate-like portion 34 is bent as shown in FIG. In the third embodiment, the gap forming support portion 4C is bent so as to be in a right angle state with respect to the snow melting flat plate portion 3C. However, the present invention is not limited to this. It may be bent at an angle.

  According to the third embodiment as described above, in addition to the effects of the first embodiment, the number of parts can be reduced, and the base end portion 42 of the gap forming support portion 4C can be simply attached to the eaves 2. Since the snow plow removing apparatus 1C can be installed, manufacturing costs and installation costs can be reduced.

As shown in FIG. 11, the sandwiching portions 35 and 35 are formed in a bowl shape having a substantially L-shaped cross section facing in the vertical direction, and are provided on the roof-side surface 32 of the snow melting flat plate portion 3D. Further, as shown in FIG. 12, the connecting portion 44 has a vertical width that can be held between the holding portions 35, 35, and is provided at the distal end portion 41 of the gap forming support portion 4D.

  And when connecting both, the connection part 44 is slid and inserted in the holding parts 35 and 35 from the side, and the said connection part 44 is pinched and connected. Thereafter, a screw is inserted into the fixing hole H, both are fastened with a nut, and the base end portion 42 of the gap forming support portion 4D is fixed to the outer edge portion 2 of the roof, whereby the snow plow removing device 1D is configured. In this case, the fixing holes H may not be provided, and the connection may be made only by the holding force of the holding parts 35, 35, or after the connecting part 44 is inserted, the holding parts 35, 35 are viewed from above and below. The connecting force may be increased by pressing. In the fourth embodiment, the connecting portion 44 is formed so as to be substantially perpendicular to the gap forming support portion 4D. However, the present invention is not limited to this. What is necessary is just to form in a predetermined angle collectively.

  According to the fourth embodiment as described above, in addition to the effects of the first embodiment, the snow melting flat plate portion 3D and the gap forming support portion 4D can be tightened more strongly, and the snow melting flat plate portion 3D is in the gap. It is possible to prevent dropping from the formation support portion 4D.

  Next, a fifth embodiment of the snow plow removing apparatus according to the present invention will be described with reference to the drawings.

  FIG. 13 is a side view showing a state in which the snow plow removing apparatus 1E according to the fifth embodiment is attached to the eaves 2. Note that, in the fifth embodiment, the same or corresponding components as those in the first embodiment described above are denoted by the same reference numerals and the description thereof is omitted.

  As shown in FIG. 13, the feature of the snow scum removing device 1E of the fifth embodiment is that a warm air introduction / deflection preventing portion 36 is formed by bending the lower end portion of the snow melting flat plate portion 3E outward along the longitudinal direction. It is in. By this warm air introduction / deflection prevention unit 36, the waste heat released from the outer wall surface of the building, the air that is warmed and raised by the exhaust from the ventilation port, and the outside air that has risen in daytime temperature are more effectively separated. S is introduced. Further, since the strength in the longitudinal direction of the snow melting flat plate portion 3E is increased, the snow melting flat plate portion 3E is prevented from being bent or bent even if it is formed in a considerably long shape.

  According to the fifth embodiment as described above, in addition to the effects of the first embodiment, more warm air can be introduced into the gap S to improve the snow melting effect, and the snow melting flat plate portion 3E can be deformed. Can be prevented.

  Next, a sixth embodiment of the snow plow removing apparatus according to the present invention will be described with reference to the drawings.

  FIG. 14 is a side view showing a state in which the snow plow removing apparatus 1F according to the sixth embodiment is attached to the eaves 2. Note that, in the sixth embodiment, the same or corresponding components as those of the above-described embodiments are denoted by the same reference numerals, and the description thereof is omitted.

  As shown in FIG. 14, the feature of the snow scum removing device 1F of the sixth embodiment is that the base end portion of the gap forming support portion 4A fixed to the eaves edge 2 extends beyond the upper end portion of the snow melting flat plate portion 3A. The point is to provide a snowboard 6 that is inclined in the direction. In the sixth embodiment, the snow board 6 is inclined at an angle of about 45 degrees with respect to the horizontal direction, and its tip part projects outward from the snow melting flat part 3A. Note that the inclination angle is not limited to 45 degrees, and can be appropriately changed according to the shape of the roof, the direction of the wind, and the like. The snow board 6 is fixed to the gap forming support part 4A and the snow melting flat part 3A by bolts or the like. The snow board 6 may be directly fixed to the roof without the gap forming support 4A.

  The snowboard 6 forms a series of wind passages from the edge of the roof to the outside and upwards, so that the snow that accumulates on the roof is blown away by the wind and plays the role of preventing the growth of the snow canopy beforehand. It has come to fulfill. In addition, the snowboard 6 has corners protruding outward to make it difficult for snow to adhere to it, and it is difficult for snow to accumulate on the snowboard 6 itself by the wind. Further, since the snow melted by the inclination is discharged to the inside and below, it is difficult for the snow board 6 to accumulate snow. Moreover, since the snow board 6 is hold | maintained at the predetermined | prescribed inclination angle, it becomes easy to attach electric heating bodies, such as the tape heater mentioned above.

“Examples showing the relationship between outside temperature and snow plow removal equipment”
In this example, the above-described snow lees removing device 1A of the first embodiment was attached to the eaves edge 2 of the snow-free snow roof, and the outside temperature, the surface temperature of the snow melting flat plate portion 3A, and the temperature in the space due to the gap S were measured. This experiment was conducted from February 2, 2006 to February 10, 2006 with the cooperation of the Hokkaido Prefectural Institute of Northern Architecture, and the above temperatures were measured every 5 hours. The result is shown in FIG.

  As shown in FIG. 15, the outside air temperature did not exceed 0 ° C. during the experiment, but the surface temperature of the snow melting flat plate portion 3A exceeded 0 ° C. after noon on any day. It has been shown. In particular, on February 4th, 5th, and 8th, the surface temperature of the snow-melting flat plate portion 3A exceeded 20 ° C., and it was shown that the temperature was considerably high depending on the weather and the degree of sunshine. In addition, the temperature in the space due to the gap S was generally maintained at a temperature higher than the outside air temperature, and exceeded 0 ° C. on February 4, 5, 8, and 10.

  Moreover, FIG. 16 is a cross-sectional photograph of snow and snow plows stacked on a snow-free roof. As shown in FIG. 16, snow melted in a sherbet-like manner at the portion in contact with the snow plow removing device 1 </ b> A and the space periphery by the gap S, and the snow melting effect was visually recognized. Moreover, FIG. 17 is an external view photograph showing a building in which the snow lees removing device 1A of the first embodiment is attached to a part of the eaves. As shown in FIG. 17, the eaves to which the snowfall removing device 1 </ b> A is not attached (the left side of the photograph) grows so that a huge snowfall extends, whereas the eaves to which the snowfall removing device 1 </ b> A is attached (the right side of the photograph) There was almost no growth of snow leopards.

  As described above, according to the present embodiment, it was shown that the space formed by the snow melting flat plate portion 3A and the gap S is maintained at a temperature higher than the outside air temperature. In fact, it has been proved that the snowfall removing device 1A of the first embodiment has a remarkable effect of removing snowfall.

  On the other hand, an experiment similar to the above example was also performed at the Shinjo branch of the Nagaoka Snow and Ice Disaster Prevention Research Institute, National Research Institute for Disaster Prevention. As a result of observing the situation of the snowfall, the snowfall in the natural state did not fall, but the snowfall that can be made in the place where the present invention is installed is in a way that the snowfall is broken above the snow melting flat plate portion 3A installed vertically. In addition, it was seen that a part of the snow ridge in contact with the outside of the snow melting flat plate portion 3A fell. Further, since the gap between the snow melting flat plate portion 3A and the wall surface has good ventilation, the temperature of the gap tends to increase during the day.

  Based on the observation results of the above embodiment, the mechanism for removing the snowfall by the snowfall removing device 1A is examined. If the snowfall is cut by the snowmelt flat plate portion 3A and falls, the snow is compressed and fractured immediately above the snowmelt flat plate portion 3A. It is thought that this is due to shear fracture in the upper part. In either case, it is the gravity that acts on the snow crab itself that causes destruction. Moreover, if the snowfall falls from the middle of the snow lump existing outside the snow melting flat plate portion 3A when the snowfall falls, it is considered that it is due to tensile failure. In this case as well, destruction occurs due to the gravity acting on the snow fence. As a result of the observation, the snowfall was falling almost like the latter.

  In addition, the snow leopard is composed of snow crystal particles or crushed snow particles at the beginning of formation, but in a cold environment, the bonding between the particles becomes stronger with time and changes into a tight snow. Shimari Snow has a high breaking strength and does not fall easily. However, when heat is supplied to the snow leopard and the snow temperature reaches 0 ° C., melting begins, and the snow is changed into rough snow. Since the breaking strength of the rough snow is smaller than that of the heavy snow, it is considered that the snow can easily be broken and fall.

  On the other hand, free convection from the wall heated by solar radiation may carry heat to the gap, and the temperature of the gap during the day may be higher than the air temperature, but the heat on the wall will be diffused by the wind. There are many. In addition, judging from the falling state of the snow canopy, the heat transmitted to the snow is considered to be important due to conduction from the snow melting flat plate portion 3A. This temperature is determined by absorption of solar radiation, turbulent heat from the air in the gap, and exchange of radiant heat between the walls. Therefore, in order for the snow plow removing apparatus 1A to function more effectively, it is preferable that the snow melting flat plate portion 3A has a height that does not completely cover even a large snow pail. As a result, the exposed part absorbs solar radiation, and it can be expected that the snowfall will become rough due to temperature rise. It is also effective to form a wide gap so that air can also enter the gap between the snow melting flat plate portions 3A when the temperature rises.

  In addition, the snowfall removing devices 1A to 1F according to the present invention are not limited to the above-described embodiments, and can be appropriately changed.

  For example, although the snow plow removing devices 1A to 1F are illustrated as being provided on a roof or a roof, they may be arranged on a parapet such as a veranda.
