[Technical field to which the invention belongs]

 In the invention of the present application, the roof tiles can be fixed simply by using one roofing nail for each roof tile to fix the upper and lower ends of the roof tile, and it is blown off by a strong wind such as a typhoon or when a large earthquake occurs The present invention relates to a roofing nail that can realize a roofing method that does not have a risk of the tiles slipping off.

[0002]

[Prior art]

 Conventionally, the general method of roofing tiles is to install a horizontal rail on the roof board, hook the protrusion at the upper end of the back of the tile on the horizontal rail, and place a nail in the nail hole near the center of the width of the upper end of the tile. It is fixed by driving it into the horizontal rail. The roof tile disclosed in Japanese Patent Application Laid-Open No. H11-324230 is used in this method, and the tile itself is slightly improved. In this method, the lower end of the roof tile is easily lifted up, so there is a high possibility that it will be blown off by a strong wind such as a typhoon. Is absolutely unbearable. In this method, there is an instability that the tile cannot be stably placed on the ground board, and it is difficult to drive nails and it is difficult to position the tile.

[0003] Next, there is a vertical bar construction method improved to stabilize the roof tile. In this method, a horizontal rail is provided on the ground board, a vertical rail is provided, a protrusion at the upper end of the back of the tile is hooked on the horizontal rail, and a vertical groove provided on the back of the tile is fitted to the vertical rail. Stabilize the tile, fix the tile by passing a nail through the nail hole provided near the center of the width of the upper end of the tile and driving it into the horizontal rail. Roof), and then the next row. This method has been adopted by tile construction shops nationwide that belong to the vertical bar association. In this method, vertical blackout was required to accurately set up the vertical bar. At this time, a spirit level could not be used, and skill and great labor were required for blackout. Moreover, since the tiles are laid in the vertical direction (upward in the inclined direction), it is more troublesome than the work of stabilizing the tiles and nailing them in the horizontal direction. In this method, the upper end of the roof tile is fixed with a single nail, and the lower end of the roof tile is merely overlapped with the lower roof tile. There is a great deal of danger, and it cannot be tolerated to guarantee that the roof tiles will not be blown away by strong winds or displaced or dropped by a major earthquake for ten years after construction.

[0004] Japanese Patent Application Laid-Open Nos. 10-096298 and 11-172856 disclose an invention that prevents the lower end of the tile from being lifted by connecting the tile that overlaps on the upper side with the tile that overlaps on the lower side by a metal fitting. JP-A-11-303323 and JP-A-11-336264 are known. The invention disclosed in Japanese Patent Application Laid-Open No. 10-096298 is to fix and fix a vertically overlapping tile with a nail and a relatively large fixing tool. If the material of the nail and the fixing tool is changed, chemical corrosion proceeds. If the nail is made of stainless steel, the fixture must also be made of stainless steel. However, if the nail is made of stainless steel, the fixture becomes expensive and the cost of the fixture in the construction cost increases. Therefore, stainless steel fasteners could not be used, and stainless steel nails could not be used. In addition, there is a problem that a gap is formed between the roof tile overlapping the upper side and the roof tile overlapping the lower side by the thickness of the metal fitting, and the waterproofness is reduced. In addition, since it is separated into a nail and a fixture, handling is troublesome. The invention of Japanese Patent Application Laid-Open No. 11-172856 discloses a method in which tiles are arranged and fixed in a staggered manner with nails and L-shaped fittings. Since the L-shaped fittings must be further bent, the thickness is large and the strength is high. However, large fittings could not be adopted. Furthermore, changing the material of the nail and the L-shaped bracket causes chemical corrosion, so if the nail is made of stainless steel, the L-shaped bracket must also be made of stainless steel, but if the L-shaped bracket is made of stainless steel, Due to the problem that bending was not possible, stainless steel nails and L-shaped brackets could not be adopted. In addition, since it is separated into nails and L-shaped brackets, handling is troublesome. In the invention of Japanese Patent Application Laid-Open No. H11-303323, a nail hole is formed not only at the upper end but also at the lower end of the tile, and when the upper tile is laid, the nail is bent into an L-shape through the nail hole at the lower end of the tile. In this method, the lower part of the upper tile is overlapped on the upper part of the lower tile, and the lower surface of the lower tile is hooked with the L-shaped nail. This method not only requires two nails, but also takes a great deal of effort to bend or rotate and pinch it. In addition, if the nail bent into an L shape rotates, the hook will be released. There are drawbacks. The invention of Japanese Patent Application Laid-Open No. H11-336264 discloses a method in which two tiles and two fixing tools are used to hold and fix vertically overlapping tiles on one roof tile. If the nails are made of stainless steel, the fasteners must be made of stainless steel.However, if the nails are made of stainless steel, the fixtures will be expensive, and the cost of the fixtures will account for the construction cost. However, there was a problem that the bulk increased. Also, handling was troublesome because it was separated into nails and fixtures.

[Problems to be solved by the invention]

 The present invention has been devised in view of the above points, and requires only one nail for one roof tile, which eliminates the need for easy nails and fixtures, and lifts not only the upper end but also the lower end of the roof tile. It can be fixed so that it does not rise, and there is no risk of being blown off by a strong wind such as a typhoon, or of falling off the tile due to vibration when a large earthquake occurs. The purpose of the present invention is to provide a roofing nail capable of realizing a roofing method capable of withstanding a ten-year defect guarantee after construction, without a gap being formed in the overlapping portion of the tiles on the side and having a function as a snow stopper. And

[0006]

[Means for Solving the Problems]

 According to the invention of the present application, a straight wire portion having a required length, which is formed by bending a single steel wire rod, has a sharp end, and is driven into a cross rail or a field board through a nail hole of a roof tile and fixed. From the upper end of the straight section for use, an arm section of a required length that is bent substantially at a right angle, and a hook section that extends in an L-shape from the overhanging end of the arm section and holds the lower end section of the roof tile stacked on the upper stage It is intended to provide a nail for roof tiles having a special shape.

[0007]

[Embodiment of the invention]

 The roof nail 4 of the present invention will be described with reference to the roofing method shown in FIGS. The nail 4 for roof tiles of the present invention is formed by bending a single stainless steel wire having a diameter of, for example, 2 to 3 mm. A driving straight portion 4a of a required length to be fixed, an arm portion 4b of a required length extending from the upper end of the driving straight portion 4a at a substantially right angle, and an L-shape from the projecting end of the arm portion 4b. It is formed in a special shape including a hook portion 4c that extends so as to be folded back and holds the lower end portion of the ceramic tile 3 stacked on the upper stage.

[0008] In the tile 4 for nailing of the present invention, the driving straight portion 4a is passed through a nail hole 3a provided at the upper end of the ceramic tile 3, and the upper end of the driving straight portion 4a is hit with a hammer to drive the horizontal beam 2 and the like. And hit it on the road board 1. At this time, since the hook portion 4c is separated from the upper end of the driving straight portion 4a, there is no problem in driving with a hammer. Then, the arm portion 4a is inclined downward toward the driving straight portion 4a.

The nail 4 for roof tiles of the present invention is obtained by hitting the horizontal rail 2 on the roof board 1 with a nail, and hooking the projection at the upper end of the rear surface of the ceramic tile 3 on the lower horizontal rail 2 in the inclination direction. The driving straight portion 4a is passed through a nail hole 3a provided in the vicinity of the center of the width of the upper end of the ceramic tile 3 and driven into the horizontal rail 2 and the field board 1 to be fixed. In addition, as in the vertical beam construction method described in the description of the related art, a vertical beam may be further provided on the horizontal beam 2 and the tile may be laid in the vertical direction.

The nail 4 for roof tiles of the present invention sandwiches the lower end of the ceramic tile 3 stacked on the upper stage between the arm portion 4b and the hook portion 4c, and provides the lower surface of the lower end of the ceramic tile 3 stacked on the upper stage. The recessed strip 3b is fitted to the arm 4b. Accordingly, the nail 4 and the ceramic tile 3 are stable without rotating around the driving straight portion 4a. And even if the wire diameter of the roofing nail 4 is made as large as 2 to 3 mmΦ, it is possible to secure a close overlap between the lower tile and the upper tile.

The nail 4 for roof tiles of the present invention is not limited to the method of roofing a ceramic tile, but may be applied to the method of roofing an S-shaped tile or a method of roofing a flat tile (slate tile). In the roofing method of the flat tile shown in FIG. 3, the horizontal rail is not used. The flat roof tile 5 has an upper end in close contact with the field board 1 and is fixedly driven into the field board 1 by passing the driving straight portion 4a of the roofing nail 4 through the nail hole 5a. The ridge 5b provided on the back surface is fitted into the arm 4b while being closely attached to and overlapped by the arm 4b and the hook 4c of the roof nail 4.

[Effect of the invention]

 The tile for nails of the present invention has the following effects. (1) A specially shaped tile nail made by bending a single steel wire rod. Since the tile nail is not two parts, even if the tile nail is made of stainless steel, the cost can be kept small. It is possible, and there is no danger of chemical electro-corrosion, which occurs when nails and fixtures are separated, and it can fully withstand the warranty for 10 years after construction. (2) Since the concave streak provided on the back surface of the lower end of the roof tile is fitted to the arm of the roof tile, the wire diameter of the roof nail can be increased, and one steel wire can be used. A specially shaped roofing nail that is bent and made of stainless steel can be used, so the snow on the roof tends to slide down on the roofing nail hook that clamps and fixes the lower end of the roofing tile. The strength and durability enough to withstand the load can be ensured, and thus, it has the function of snow stopper and can withstand 10 years of defect guarantee. In addition, there is no need to separately attach a snow stopper, which saves labor. (3) Roofing nails of a special shape, capable of fixing the upper end of the roof tile, holding and fixing the lower end of the roof tile overlapping on the upper side, and forming the concave streak provided on the back surface of the lower end of the upper roof tile. When the upper and lower tiles are fitted to each other, there is no gap in the overlap between the upper and lower tiles, which causes a decrease in waterproofness. (4) Roofing nails of special shape, which can fix the upper end of the roof tile and can clamp and fix the lower end of the roof tile that overlaps the upper side, so only one nail is required for one roof tile. Compared with the conventional method of fixing the upper end of the roof tile using nails and fixtures and holding and fixing the lower end of the roof tile that overlaps above, the number of parts is small and the handling is easy. (5) A specially shaped roofing nail made by bending a single steel wire rod. The roofing nail can be fixed by fixing the upper end of the roofing tile and holding the lower end of the roofing tile on the upper side. There is no danger that the roof tiles will be dislodged by the blown-out or vibrations of a large earthquake.
