Abstract

(57) [Abstract] [Purpose] Ventilate the roof and prevent rainwater from entering the ventilation holes. [Structure] A flat roof tile main body 1 is provided with a number of ventilation holes 2 penetrating from the eaves side to the ridge side. A projecting edge portion 7 projecting toward the eaves is formed over the entire length at the upper edge of the eaves-side end surface of the flat tile main body 1 in which the vent holes 2 are opened.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a flat roof tile, and more particularly to a technique for improving the appearance by ventilating the roof surface and making the ventilation holes invisible in such a case, and preventing rainwater from entering the ventilation holes. .

[0002]

[Prior Art]

 Conventionally, the flat roof tile 1a has a substantially uniform thickness, and as shown in FIG.

[0003]

[Problems to be solved by the device]

 However, with such a structure, it is impossible to ventilate the roof surface that is covered with the flat tile 1a. The present invention is intended to solve such a problem, and an object thereof is to enable ventilation of the roof surface even though it is a flat roof tile, and to make the ventilation hole in such a case invisible. The purpose of the present invention is to provide a flat roof tile that enhances the external appearance and prevents rainwater from entering the ventilation holes.

[0004]

[Means for Solving the Problems]

 The flat roof tile of the present invention has a plurality of ventilation holes 2 penetrating from the eaves side to the ridge side of the flat roof tile body 1, and the ventilation holes 2 are open on the eaves side end surface of the flat roof tile body 1. It is characterized in that the edge portion is formed with a projecting edge portion 7 projecting to the eaves side over the entire length.

[0005]

[Action]

 In this way, a plurality of ventilation holes 2 penetrating from the eaves side to the ridge side are formed in the flat tile main body 1, and at the upper edge of the eaves side end surface of the flat roof tile main body 1 where these ventilation holes 2 are open. By forming the projecting edge portion 7 projecting toward the eaves over the entire length, the ventilation holes 2 penetrating in the flat roof tile main body 1 in the eaves ridge direction allow the flat roof tile main body 1 to pass through the entire length in the eaves ridge direction. Ventilation is performed on the roof surface to avoid temperature rise on the roof surface, ventilation is performed using ventilation holes 2 to exhaust air, cooling is performed, and ventilation holes 2 are opened. By forming the projecting edge portion 7 projecting toward the eaves over the entire length at the upper edge portion of the eaves side end surface of the flat tile main body 1, the projecting edge portion 7 projects like an eaves-like shape, and the vent hole 2 cannot be seen. In this way, the appearance is improved, and rainwater is prevented from entering the ventilation hole 2, and Without impairing the function, in which so as to avoid the narrowing down along the rain water from the vent 2.

【Example】

 The flat roof tile A is extruded from, for example, a ceramic material, the flat roof tile main body 1 has a substantially uniform thickness, and the overlapped portion 5 is formed on the side of the flat roof tile. A large number of ventilation holes 2 are formed in the flat tile main body 1 so as to penetrate in the direction of the eaves. The flat roof tile body 1 is provided with a fitting projection 3 at one end on the end side and a fitting recess 4 at the other end on the end side for fitting with the fitting projection 3 in a mutually interlocking manner. There is. A drainage groove 6 is formed in the fitting convex portion 3. In addition, a projecting edge portion 7 that projects toward the eaves over the entire length is formed at the upper edge of the eaves side end surface of the flat tile main body 1. Then, the roofing 9 is laid on the roof substrate 11 such as a base plate, and the flat roof tile A is fitted on the flat roof tile A by fitting the fitting convex portion 3 and the fitting concave portion 4 together. In the eaves direction, the eaves side portion of the flat tile A on the ridge side is overlapped with the overlapped portion 5 of the flat tile A on the eave side in the eaves direction. In such a case, by forming the projecting edge portion 7 projecting toward the eaves over the entire length at the upper edge portion of the eaves side end surface of the flat roof tile main body 1 in which the vent hole 2 is opened, the projecting edge portion 7 becomes an eaves shape. The protrusion prevents the rainwater from entering the ventilation hole 2, does not impair the ventilation function of the ventilation hole 2, and avoids the transmission of rainwater from the ventilation hole 2. In this way, a large number of ventilation holes 2 are formed in the flat tile main body 1 from the eaves side to the ridge side, and the ventilation holes 2 are open at the upper edge of the eaves side end surface of the flat roof tile main body 1. By forming the projecting edge portion 7 projecting to the eaves side over, the ventilation hole 2 penetrating in the flat roof tile body 1 in the eaves ridge direction allows ventilation in the entire length of the flat roof tile body 1 in the eaves ridge direction. Ventilation is performed on the roof surface to prevent the temperature of the roof surface from rising, ventilation is performed using the ventilation holes 2 to exhaust air, cooling is performed, and the ventilation holes 2 are open. By forming the projecting edge 7 projecting toward the eaves over the entire length at the upper edge of the eaves side end face of 1, the projecting edge 7 projects like an eaves and rainwater enters the vent hole 2. To prevent rainwater from passing through the vent hole 2 without impairing the ventilation function of the vent hole 2. It is intended to avoid.

[0007]

[Effect of the device]

 As described above, the present invention forms a number of vent holes penetrating from the eaves side to the ridge side in the flat tile main body, and at the upper edge of the eaves side end surface of the flat tile main body where these vent holes are opened. Since the projecting edge that protrudes toward the eaves is formed over the entire length, ventilation holes can be provided in the flat tile main body toward the eaves toward the eaves, and ventilation can be achieved over the entire length of the flat tile main body in the eaves direction. Ventilation can be done to avoid raising the temperature of the roof surface, ventilation is used to exhaust air, cooling is achieved, and the eaves-side end surface of the flat roof tile body with the ventilation holes open. Since the projecting edge projecting toward the eaves is formed over the entire length at the edge, the projecting edge projects like an eaves, and the ventilation hole is invisible to enhance the appearance and rainwater penetrates into the ventilation hole. Can be prevented and impair the ventilation function in the vent hole. DOO without, there is an advantage to avoid the narrowing down along the rain water from the vent.
