[Problems to be solved by the device]

 Since the conventional metal roof tiles are assembled via the horizontal stake, the horizontal stake is indispensable, and the installation work is troublesome. In addition, since many of these horizontal piers cross the roof surface, and more than one is provided between the ridge and the eaves, the air flowability of the roof surface deteriorates, and dew condensation occurs on the roof surface and its underlying material, causing corrosion. It is easy and causes early damage. Furthermore, since each metal tile is fixed by a horizontal stile, the sliding adjustment between the metal tiles cannot be performed, and it is difficult to match the length with the roof surface. The present invention has been made in consideration of the above circumstances, and an object thereof is to provide a metal roof tile that does not require a horizontal crosspiece, improves air circulation, and allows mutual slide adjustment.

[0004]

[Means for Solving the Problems]

 According to the present invention, a semi-cylindrical straight portion 2 is formed by projecting from a flat portion 4 in the front-rear direction of the molded body, and a semi-circular flap in the left-right direction of the rear portion of each straight portion 2 of the molded body. A ridge-shaped ridge 14 provided with a hook portion 7, a rear bulge portion 13 and an opening 16 bulged to the rear of the ridge 14, and a front portion of the straight portion 2 extending downward. A metal roof tile 1 including a front projection 3 having a semicircular opening 6 formed by being raised on an extension line of each strut 2, and a plurality of roof tiles 20 on the roof surface 20. When these metal roof tiles 1 are connected and fixed to each other, air passages 5 and 9 which communicate with each other in the front-rear and left-right directions are formed on the back surface thereof by the straight portion 2 and the ridge-like ridge portion 14, and the semicircle is also formed. The opening 6, the semi-cylindrical strut 2 and the semi-circular hook 7 are mutually connected. Is a metal tile 1, characterized in that it can be adjusted fixed at an appropriate position in the backward direction by the child sliding.

[0005]

[Action]

 By hooking the engagement step of the straight part of one metal roof tile to the engagement part of the hook part of another metal roof tile, the metal roof tile is extended and assembled in the front-rear direction, eliminating the need for a horizontal cross bar. Roofing is possible. In addition, air flows through the entire roof surface by the air passages that communicate in the front-rear and left-right directions of the straight portion and the hook portion. In addition, the roof tiles can be slid on each other and the length of the roof tiles can be adjusted according to the roof surface.

【Example】

 The present invention will be described with reference to the embodiments shown in the drawings. FIG. 1 shows a metal roof 1 according to an embodiment of the present invention. The metal roof 1 is formed into a shape as shown by pressing a steel plate. The size or length of the metal roof 1 can be arbitrarily determined. The entire surface of the metal roof tile 1 is plated with rust and water resistance, and the upper surface is coated with Teflon resin such as polytetrafluoroethylene. By this coating, the surface tension of the top surface of the metal roof 1 is reduced, and rainwater, snow and dust are less likely to adhere to the surface. The molded body of the metal roof tile 1 shown in FIGS. 1 to 8 has two semi-cylindrical straight portions 2 and 2 having a substantially semicircular cross section, which are parallel to each other in the front-rear direction, and are formed in a protruding manner. A ridge-shaped ridge-shaped ridge 14 having a substantially trapezoidal cross-section and having a semicircular hook portion 7 orthogonal to the straight portions 2 and 2 is formed. On the other hand, when the roof surface 20 shown in FIG. 5 is used as the reference surface 12 of the metal roof tile 1, the front overhang portion 3 and the rear overhang portion 13 are flattened along the reference surface in front of and behind the metal roof tile 1. It is overhanging. The raised straight portions 2 and 2 are connected to each other by the flat portion 4, but a concave draining groove 11 is formed in the connecting portion between the straight portion 2 and the flat portion 4 as shown in FIG. . Further, a semi-circular opening 6 that fits into the semi-circular cross section of the straight portion 2 is formed on the front overhanging portion 3 so as to be superposed on the straight portion 2 so as to be superposed. Moreover, the front step portion of the flat portion 4 is formed so as to be raised higher than the above-mentioned front overhang portion 3, and the straight portion 2 is formed in a corrugated protrusion with respect to the flat portion 4 from the front side. When viewed, the ridgeline structure formed by the flat portion 4 and the straight portion 2 is formed in parallel with the ridgeline structure formed by the front protrusion 3 and the opening 6, and thus the ridgeline structure of FIG. As described above, it is possible to fit the opening portion 6 of the metal roof tile 1 on the upper rear side to the straight portion 2 of the metal roof tile 1 on the lower front side and slide it in the front-rear direction.

On the other hand, as shown in FIG. 2, the flat portion 4 gradually inclines toward the rear projecting portion 13 with respect to the reference plane 12 in the front-back direction, and the trapezoidal ridge portion 14 at the rear portion projects rearwardly from the rear wall. The front wall of the portion 13 is formed to rise from the rear end of the flat portion 4 at a position slightly higher than the reference surface 12. Further, the front lower metal roof tile 1 can be hooked on the top wall 15 of the ridge-like ridge 14 by the engaging step portion 8 of the rear upper metal wall 1 as shown in FIG. A semi-circular hook portion 7 that can be fitted to the back surface of the semi-circular cross section of the straight portion 2 is formed so as to allow the front and rear metal roof tiles 1 and 1 to slide with each other. The ridge-like ridge structure formed by the top wall 15 of the ridge-like ridge 14 with the hook portion 7 is formed in parallel with the ridge structure formed by the flat portion 4 and the straight portion 2. Therefore, the straight portion 2 of the metal roof tile 1 on the upper rear side can be slid onto the hook portion 7 on the lower front side or can be stably placed. Further, the engagement step portion 8 at the tip of the straight portion 2 is formed so as to incline in a concave shape with respect to the front step portion of the flat portion 4, but the hook portion 7 of the other party can also be engaged with the engagement step portion 8. As described above, the metal roof tiles 1 and 1 in the front-rear direction are continuously fixed to each other by being inclined and formed in a concave shape. The shape between the engagement step portion 8 and the hook portion 7 is not limited to the illustrated shape as long as it can be hooked. A semi-circular opening 16 is also formed upright on the rear overhanging portion 13, but the shape is not limited because it is for an air flow path.

Since the molded body is thus bent and formed, an air passage 5 (FIG. 2) in the front-rear direction from the front opening 6 to the rear opening 16 is formed on the back surface of the straight portion 2. The air passage 9 (FIG. 2) is formed on the back surface of the raised portion 14 over the entire length in the left-right direction. Since the air flow passage 9 of the raised portion 14 is formed so as to communicate with the air flow passage 5 of the straight portion 2 at right angles, the air flow passages 9 and 5 allow the air on the roof surface to be described later. The flowability is dramatically increased. Drainage grooves 10 and 11 are formed on both sides of the top wall 15 of the ridge-shaped raised portion 14 of the metal roof tile 1 and the straight portion 2. As shown in FIGS. 1 and 2, the drainage groove 10 is formed over the entire length of the top wall 15 by bending the top wall 15 of the ridge-shaped ridge 14 into a line. This drainage groove 10 is for preventing further movement of rainwater even if the rainwater travels on the surface of the lower front side of the metal tile 1 and intrudes over the rear raised portion 14 due to a capillary phenomenon. The purpose is to eliminate the risk of flooding the roof surface 20 (Fig. 5). Further, as shown in FIGS. 1 and 3, the drainage groove 11 of the straight portion 2 is formed in the front-rear direction over substantially the entire length of the straight portion 2 by bending both side surfaces of the straight portion 2. This drainage groove 11 prevents rainwater from traveling in the lateral direction along the upper surface of the metal roof tile 1.

Next, FIG. 4 and FIG. 5 show a procedure for roofing with the above-mentioned metal tile 1. As shown in FIG. 4, the metal roof tile 1 is assembled by being stretched in the front-back direction so that the extension lines of the straight portion 2 are continuously provided, and the hook portion 7 of the front metal roof tile 1 is connected to the straight portion of the rear metal roof tile 1. The engagement step portion 8 of the portion 2 is fitted. As a result, as shown in FIG. 5, the two metal roof tiles 1 and 1 in the maximum extension position have the hook portion 7 and the engagement step portion 8 hooked to each other on the roof surface 20. It is fastened continuously in the front-back direction. Then, by repeating this work along the roof surface 20, the entire roof surface 20 is covered with the metal roof tile 1 as shown in FIG. In such roofing, the metal roof tiles are positioned and fixed relative to each other by the engagement of the hook portion 7 and the engagement step portion 8 of the straight portion 2, so that a horizontal stake is not required, and work for attaching the horizontal stake is performed. Since it is unnecessary, the construction period can be greatly shortened. In addition, since the horizontal stake is not required, the ventilation of the roof surface is improved in combination with the communication of the air flow path. Further, in the assembled state by the roofing, the air passage 5 under the straight portion 2 communicates with the front-rear direction, and the air passage 9 on the back surface of the raised portion 14 communicates with the left-right direction.

Then, as shown in FIG. 6, air flows in from the opening 6 of the metal roof tile 1 located at the eaves tip portion (that is, the lowermost stage), and further communicates with the front and rear and left and right air flow paths 5, 9 and. The air flows between the metal tile and the roof surface 20 through the opening 17 to secure air communication between them. Therefore, there is no dew condensation on the roof surface 20 or its base material, corrosion caused by dew condensation is eliminated, and durability is increased. The slide adjustment between the metal roof tiles 1 which is a feature of the present invention will be described in detail with reference to FIG. According to the present invention, as described above, in addition to the need for the horizontal crosspiece, the ridge line structure formed by the straight portion 4 and the straight portion 2 of the molded body of the metal roof tile 1, the opening portion 6 and the front protrusion portion 3 are used. Since the ridge structure formed and the ridge structure formed by the top wall 15 of the ridge-shaped ridge 14 having the hook portion 7 are configured to be capable of fitting with each other, As shown in the drawing, the opening 6 of the rear upper metal tile 1 is fitted to the straight portion 2 of the lower front metal tile 1, and the straight portion 2 of the upper rear metal tile 1 is fitted to the straight portion 2 of the lower front metal tile. It can be fitted in the semicircular hook 7 of No. 1 and can be slid in the front-back direction, and when the length is appropriate, nails 21 or fasteners 21 such as screws are driven into the roof surface 20. Can be fixed. This makes it possible to easily adjust the position (length) according to the length of the roof surface 20, so that versatile assembly is possible regardless of the length of the metal roof tile 1.

FIG. 8 shows still another example of the mounting method, in which one straight portion 2 of the upper metal tile 1 is fitted to one straight portion 2 of the lower metal tile 1 to attach the metal tiles to each other. It is assembled by shifting it to the left and right direction, and such a method further expands the freedom of construction. In the present invention, the drainage groove 11 of the straight portion 2 may be omitted, and other various modifications are possible.

[0012]

[Effect of device]

 As described above, according to the present invention, since the front hook portion is engaged with the front portion of the rear straight portion to fix the metal roof tiles to each other, the horizontal crosspiece is not required on the roof surface. Also, since the metal roof tiles can be slid on each other to adjust the position, it is possible to easily fit the length of the roof surface. In addition, since the air passages formed in the straight portion and the hook portion ensure the air permeability of the roof surface, there is no dew condensation and the durability is improved.
