[Industrial applications]

 The present invention relates to improvement of roof tiles.

[0002]

[Prior art]

 In general, roof tiles are nailed and fixed to the crosspieces to prevent the tiles from flying due to strong wind. In addition, a water burr is projected from the bottom edge of the roof tile body surface that connects the peaks and valleys to the side edge of the valley to prevent rainwater backflow and prevent it from entering the back side of the roof tile body. ing.

[0003]

[Problems to be solved by the device]

 Although it is possible to firmly fix the roof tiles by striking multiple nails per sheet when roofing the roof tiles, the efficiency of the roofing work is significantly reduced, so one nail is usually used to nail the roof tiles. However, striking with a single nail is not sufficient as a measure to prevent the tiles from scattering against a strong wind such as a typhoon. Also, in the case of roof tiles provided with water burr, it is possible to prevent rainwater from entering more reliably by raising the water burr, but the high water burr is damaged during the roof tile roofing work and transportation work. It is easy, and the height of the jetty is limited because another roof tile's head and peaks are piled up on the bottom and valley of the main body when the roof is being erected. Therefore, in rainy weather with strong winds, rainwater may get over the backwater and enter the back of the roof tile body. The present invention has been made in view of the above problems, and an object of the present invention is to provide a roof tile that is excellent in workability for erection and that can effectively prevent rainwater from entering the back side of the roof tile body. .

[0004]

[Means for Solving the Problems]

 In the roof tile according to claim 1, a cut is formed in a corner portion of a roof portion of the roof tile body in which a mountain portion and a valley portion are formed, and a notch is formed in a corner portion of a roof portion of the roof tile body. Form a butt-side cut into which the cut fits and form a complementary shape with the cut at the corner of the front edge, and form a recess on the lateral end face of one of the cuts, and on the lateral end face of the other cut. It is characterized in that a projection fitted to the recess is provided. The roof tile according to claim 2 is the roof tile according to claim 1, in which a water repellent of the valley edge is provided at a side edge of the valley on the surface of the tile main body, and is flat in parallel with the water repellent of the valley edge. The inner water repellent with a flat upper surface is projected, and a stepped portion having a required width is formed on the side edge of the mountain portion on the rear surface of the roof tile body so as to be laterally adjustable and overlapped with the upper surface of the inner water repellent. A roof tile is provided with play so that the protrusion is laterally adjustably inserted into the recess.

[0005]

[Operation and effect of the device]

 According to the roof tile according to claim 1, the protrusion or the recess on the front side of one roof tile is fitted with the recess or the protrusion on the butt side of the roof tile located one step below the roof tile. By doing so, the two roof tiles are connected. By connecting two roof tiles in a specific positional relationship in this way, the roof tiles of the entire roof can be connected together, so that even if exposed to strong winds, the individual roof tiles will not rise easily. Therefore, the required strong wind resistance can be obtained by striking only one nail, and it is not necessary to fix one roof tile with multiple nails, which improves the efficiency of the roofing work. According to the roof tile according to claim 2, in addition to the water repellent at the valley edge on the surface of the roof tile, an inner water repellent is provided to form the water repellent in two steps, and the roof retreat is provided at the mountain side edge on the back surface of the roof tile main body. Since the step portion is overlapped with the inner water repellent, water can be stopped not only at the water repellent at the valley edge but also at the inner water refill and the step portion overlapping with the inner water reef. Therefore, it is possible to effectively prevent rainwater from crossing over the edge of the valley and entering the back side of the main body. When stacking the roof tiles adjacent to the roof tiles of one roof tile by overlapping them with each other, the horizontal position of the overlapping position of the inner water catcher and the step and the fitting position of the recess and the protrusion should be set horizontally. Since the adjustment can be made in any direction, the flexibility of the caving work is increased and workability is improved.

【Example】

 The present invention will be described below with reference to the drawings. FIGS. 1 to 3 show a roof tile 10 according to an embodiment of the present invention. The main body of the roof tile 10 is formed by connecting a mountain portion 11 and a valley portion 12 to each other, and a bottom portion 10a of the mountain portion 11 has a narrow width to form a step portion 13. On the surface of the main body, a water drop 14 on the bottom edge and a water drop 15 on the bottom edge are projected from the edge on the bottom side 10a to the side edge on the valley side. The inner water return channels 16, 17, 18 are provided in a convex shape, and the drainage channels 19, 20, 21 are defined by these water return channels 15-18. The inner water return 18 has a flat upper surface. The inner water repellents 16, 17 arranged in the middle of the water repellent 15 at the valley edge and the inner water repellent 18 are set lower than the water repellents 15, 18 on both sides. The drain groove 19 and the drain groove 20 communicate with each other through a passage 22, and the drain groove 21 and the drain groove 20 communicate with each other through a passage 23. The drainage groove 20 and the valley portion 12 communicate with each other through a passage 24. Further, the drainage groove 20 communicates with a notch 25 formed at a corner of the foreside 10b of the valley 12 of the roof tile body 10. On the other hand, a cutout 26 having a shape complementary to the cutout 25 on the foreside 10b is formed at a corner portion on the rear side 10a of the mountain portion 11 of the roof tile body 10.

A slit 27 is formed on the lateral end face of the notch 25, and the slit 27 is open at the vertical end face of the water return 15 at the valley edge. On the other hand, on the lateral end surface of the notch 26, a protrusion 28 is provided to be fitted in the slit so as to be adjustable in the lateral direction with play. Nail holes 29 are formed on the rear side 10a of the valley 12 on the front surface of the roof tile body 10, and pedestals 30 to 34 are provided at the edges of the rear side of the rear roof body 10 on the rear side 10a. At the side edge of the mountain portion 11 on the back surface of the roof tile body 10, a step portion 35 having a required width is formed on the flat upper surface of the inner water return 18 so as to be laterally adjustable, and the small edge side of the roof surface of the roof tile body 10 is formed. A pedestal 36 is provided in series at the edge of the ridge from the edge of the mountain to the edge of the valley.

The roof tile 10 according to the present embodiment has the above-described configuration, and FIG. 4 shows a procedure for constructing the roof tile 10. First, the roof tile 10A is placed and nailed through the nail hole 29 to the crosspiece. Next, the bottom side 10a of the roof tile 10A and the small edge side 10b of the roof tile 10B are overlapped and placed. At that time, the pedestal 36 of the roof tile 10B is brought into contact with the step portion of the roof tile 10A to determine the vertical position of the roof tile 10B and then nailed. In this way, roof tiles are laid in a line in a vertical direction, and the roof tiles 10A, 10B ... Are fixed to the crosspieces. Next, the mountain portion 11 of the roof tile 10C is overlapped with the valley portion 12 of the roof tile 10A, the step portion 35 is overlapped with the inner water repellent 18, and the roof tile 10C of the roof tile 10C is inserted into the small cutout 25 of the roof tile 10B. The rear cutout is fitted, the projection 28 is fitted in the slit 27, and the roof tile 10B and the roof tile 10C are connected. At that time, as schematically shown in FIGS. 5A and 5B, the roof tile 10C is moved laterally with respect to the roof tile 10A by moving the roof tile 10A to the valley portion 12 and the roof tile 10C to the mountain portion 11C. The overlapping position of is properly adjusted within the range allowed by the width of the step portion 35. At this time, since the protrusion 28 is fitted in the slit 27 with some play, the fitting position can be laterally adjusted.

According to the roof tile 10 according to the present embodiment, the protrusion 27 on the bottom side of the roof tile 10C located one step below the roof tile 10B is fitted in the slit 27 on the front side of the roof tile 10B. By doing so, the two roof tiles 10B and 10C are connected. In this way, by connecting the two roof tiles 10 having a specific positional relationship, the roof tiles of the entire roof can be integrally connected, so that the individual roof tiles are unlikely to rise even when exposed to strong wind. Therefore, even if only one nail is struck, the required strong wind resistance can be obtained, and since it is not necessary to fix one tile with multiple nails, the efficiency of the roofing work is improved. In addition to the water repellent 15 at the valley edge at the valley 12 on the surface of the roof tile body 10, inner water repellents 16, 17, 18 are provided to form water repellent in multiple stages, and at the side edge of the mountain portion 11 on the rear surface of the roof tile body 10. Since the provided step portion 35 is superposed on the inner water return 18, the water can be blocked not only by the water return 15 at the valley edge but also by the inner water return 18 and the step 35 overlapping the water return 18. Therefore, it is possible to effectively prevent rainwater from getting over the edge of the valley 12 and entering the back side of the main body 10. When stacking the roof 11 and the mountain portion 11 of the roof tile 10C adjacent to the valley 12 of the roof tile 10A, the position where the inner water return 18 and the step 35 overlap and the position where the slit 27 and the protrusion 28 are fitted to each other Can be adjusted in the horizontal direction, increasing the flexibility of the caving work and improving workability.
