Description

  The present invention relates to a snow stop tile having a snow stop function for preventing snow on a roof from sliding down.

In snowy areas, snow on the roof can suddenly slide down, creating danger to passers-by, and can damage rain gutters, lower roofs, windows, garden installations, automobiles, and the like. As a technique for preventing such an accident, there is known a technique in which a protrusion for snow stop is formed on the surface of a tile used for a tiled roof (for example, Patent Documents 1 to 4).

  The surface of the roof tile is usually formed in a corrugated or valley shape. However, in the conventional snow cover tile described in each of the above-mentioned documents, a protrusion for snow stop is formed at or near the valley of the surface. Has been. However, when it is raining while snow is remaining on the roof, or when a large amount of snow is slowly melting on the roof, rainwater tends to accumulate in the valleys on the tile surface, and it protrudes from the valleys. There is a risk that the protruding portion may prevent smooth rainwater flow. Then, rainwater permeates into the back side of the roof tile from the tile stacking section and impairs the waterproofness of the roof surface, or icicles such as icicles are likely to occur on the eaves.

  The present invention has been made to solve the above-mentioned problems. The surface shape including the protrusion for snow stop is improved so that rainwater can easily flow down, and rainwater stays on the surface of the roof tile for a long time. It is set as a solution subject to prevent.

  Further, the snow roof tiles described in each of the above-mentioned documents may cause the projections on the surface to be excessively conspicuous and impair the aesthetic appearance of the roof surface. Becomes inconvenient and bulky, which makes packaging and storage inconvenient and increases the transportation cost. Therefore, the present invention also proposes a shape of a snow-stopping tile that has a projecting portion that is not conspicuous and that is excellent in design, and that does not become bulky even when overlapped.

  In order to achieve the above-described object, the snow guard tile of the present invention is provided with a plurality of ridges and valleys extending along the water gradient direction on the roof surface, and a snow guard projection is formed only on the hill. It is characterized by that. According to the snow retaining tile, the snow retaining projection formed on the mountain portion can prevent snow from falling and rain water can flow smoothly from the water to the water along the valley.

  In order to make the rainwater flow more smooth, it is preferable that the underwater side of the tile surface is formed so as to have the same height as the trough over the entire working width. According to this, even if the snow-stopping tiles are staggered or there are variations in construction in the state of being rolled up, the valleys on the surface of the tiles continue from the water to the bottom, which is good. Drainage is obtained.

  The snow stopper projections are preferably formed so that the water upper side is substantially upright with respect to the roof tile surface and the water lower side is gently inclined with respect to the roof tile surface. Further, arranging the snow stopper protrusions on the plurality of mountain portions in a staggered shape when viewed from above contributes to the improvement of the snow stopping effect on the entire roof surface.

  Further, the snow stop tile of the present invention is such that the height of the protrusion for snow stop does not exceed the thickness of the tile main body, and the protrusion is not provided on the back surface of the roof tile when the snow stop tile is overlapped. A recess that can be accommodated is formed. The shape of the recess is appropriately determined according to the shape of the protrusion. According to this configuration, the protrusions are less noticeable than necessary, so that the aesthetic appearance of the roof surface is not impaired, and a plurality of snow-preventing tiles can be stacked and packed without being bulky, so the tile storage cost And transportation costs can be reduced.

  Since the snow-stopping tile of the present invention configured as described above has a protrusion for snow-stopping formed only on the mountain portion among the mountain-and-valley portion in the direction of the water gradient provided on the tile surface, The flow of rainwater along the section is not hindered, and rainwater can be prevented from staying on the surface of the snow-clad tile for a long time. If the underwater side of the tile surface is aligned at the same height as the valleys over the entire working width, the flow of rainwater flowing from the upper snowfall tile to the lower snowfall tile can be made smoother.

  The snow stopper tile of the present invention is configured such that a recess corresponding to the protrusion on the roof surface is formed on the back surface of the roof tile so that the protrusion is accommodated in the recess when the snow stop tile is overlapped. Therefore, a plurality of snow stopper tiles can be stacked and packed without being bulky in the same manner as ordinary tiles, and can be stored and transported economically.

  Furthermore, if the height of the protrusion for snow stop is set to a dimension that does not exceed the thickness of the tile body, the protrusion will not stand out more than necessary, and the aesthetic appearance of the roof surface will not be impaired. In addition, the cost of molding materials and processes is almost the same as that of ordinary roof tiles that do not have a snow stop function, and the maintenance of the mold becomes easy. be able to.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  1 to 7 show a snow stop tile 1 according to an embodiment of the present invention. The illustrated snow-stopping tile 1 is a flat roof tile having a flat rectangular shape as a whole, and the shape thereof is an F-shaped roof tile defined by the Japanese Industrial Standard (JIS) A5208 “Clay Straw” shape classification, or similar to it. Corresponds to the roof tile. The edge (head) 11 on the underside of the snow roof tile 1 hangs from the surface in a substantially L-shaped cross section, and a water return 13 and a nail hole 14 are formed on the surface of the edge (butt) 12 on the waterside. Yes. In addition, an underlap 15 that becomes a “rake side” overhangs on the left side when viewed from the underwater side, and an overlap that becomes a “covering side” when overlaid on the back side on the right side when viewed from the underwater side. 16 is missing. In addition, the shape of these peripheral parts and the overlapping part is an example, and can be suitably changed in the range which does not deviate from the basic function as a roof tile.

  The main part of the present invention is in the protrusion 2 for snow stop formed on the surface. A plurality of ridges 3 and valleys 4 extending along the water gradient direction are provided on the surface of the snow stop tile 1. In the illustrated embodiment, five ridges 3 and four valleys 4 are provided alternately. The level difference between the peak 3 and the valley 4 is about 2 mm to 5 mm. The crest 3 is laterally continuous on the water side, and the surface height in the vicinity of the edge 12 on the water side is evenly aligned with the height of the crest 3 over the entire working width. The crest 3 is interrupted at a position separated from the underwater edge 11 by a predetermined dimension, and the surface height in the vicinity of the underwater edge 12 is flat at the height of the trough 4 over the entire working width. It is aligned.

  The snow stopper protrusion 2 is formed only on the peak 3 of the peak 3 and the valley 4. As shown in FIG. 6, the protrusion 2 has a substantially rectangular shape when viewed from the top, and the vertical cross-sectional shape has a substantially right angle with respect to the tile surface on the water side (specifically, about 80 to 90 degrees), It is formed so that the rising angle with respect to the tile surface has a substantially trapezoidal shape with a gentle inclination (specifically, about 20 to 40 degrees). The height of the protrusion 2 according to the exemplary embodiment is about 10 mm, and is set to a size that does not exceed the thickness of the roof tile body at most.

  The protrusions 2 according to the illustrated embodiment are arranged in a substantially staggered manner by shifting the lateral position by a few centimeters between the central peak 3 and the left and right peaks 3 among the three peaks 3. . With respect to the arrangement of the protrusions 2, it is preferable to shift the lateral positions from the viewpoint of improving the snow stop effect, but a constant snow stop effect can be expected even if the horizontal positions of the protrusions 2 are aligned.

  According to the snow-stopping roof tile 1 of the present invention configured as described above, the protrusion 2 formed on the mountain portion 3 prevents the snow from sliding down, and the rain that has fallen during the snow and the snowmelt water that has gradually melted, The water flows smoothly down along the flat valley 4 having no protrusion 2 without staying on the surface of the snow-stopping tile 1. Thereby, the drainage nature superior to the conventional snow stop tile is obtained. Moreover, such a projection part 2 also becomes a foothold at the time of construction on the roof.

  Furthermore, in the snow-stopping tile 1 of the present invention, in order to make it easy to overlap the snow-stopping tiles 1, a recess 5 corresponding to the projection 2 on the front surface is formed on the back surface. The concave portion 5 is formed at a position coincident with the protruding portion 2 of the snow-stopping tile 1 stacked on the back surface side so that the vertical cross-sectional shape becomes a substantially triangular shape or a substantially trapezoidal shape, and as shown in FIG. The protrusion 2 to be overlaid is accommodated. Thereby, even when this snow-stopping tile 1 is overlapped, the height thereof can be made the same level as when normal roof tiles are overlapped, and the cost for packing, storage and transportation can be reduced. .

  Note that the present invention can be applied not only to clay tiles but also to ceramic roof tiles, resin roof tiles, or metal roofing materials simulating tile shapes.
