Abstract

PROBLEM TO BE SOLVED: To prevent rain water from entering through a nail hole surely for a long term by forming a projecting stripe on the circumferential edge of a recessed part for nail hole, and perfectly receiving rubber packing in the recessed part. SOLUTION: Recessed parts for nail hole 6 are provided in the vicinity of the dewatering projecting stripe of the frame ridge of a roof tile 1 and on the front hip side of the frame ridge. By deeply forming a concealed hole 8 so as to form a thin wall part 7 more thiner, a screw can be penetrated by charging the screw 9 in a screw fastening machine and pressingly screwing. A washer 11 is contacted with the flat upper end face of a projecting strip 6a formed on the circumferential edge of the recessed part for nail hole, and the recessed part 6 is perfectly covered. By forming the recessed part 6 into a volume capable of perfectly receiving a rubber packing 10, sufficient watertightness is obtained, and because the packing member is not exposed to open air, the packing member can be prevented from deteriorating.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to roof tiles used for roofing.

[0002]

2. Description of the Related Art Conventional roofing is constructed by simply stacking roof tiles on top of each other, so that it is only fixed by the weight of the roof tiles and the load of the overlapping parts of the roof tiles. Therefore, there is a problem that the roof tile easily separates from the roof. Therefore, there is adopted a method in which a through hole is formed in the roof tile and the hole is used to fasten with a wire or to fix the roof to the roof by nailing. As shown in FIG. 3, a recess which is thinner than the other parts is formed in advance in the roof of the tile as shown in FIG. 3, and nails are driven from this thin recess to fix it, or a washer and a packing member. There is a roof tile that is fixed with a screw screw through.

[0003]

However, the prior art is merely provided with a recess for the purpose of nailing. If rainwater permeates through the gaps caused by loosening of the nails, or if the screws are used to fasten the screws, the packing members are exposed and are exposed to the outside air. Since the adhesion with the roof tile is not sufficient, this also causes a problem of water leakage. The present invention has been made in view of the above problems, and an object thereof is to provide a roof tile that can reliably prevent rainwater from entering through a nail hole for a long period of time.

[0004]

Therefore, in the present invention, a thin-walled recess for screw screw penetration is provided, and the screw screw is pierced through the thin-walled recess through a washer and a packing member to fix it to the base material of the roof. In the roof tile described above, a first feature is that a protrusion (lip) is provided on a peripheral edge of an upper surface of the thin-walled recess, and a second feature is that the thin-walled recess is formed to have a volume capable of accommodating a packing member. In addition, the third feature is that the thin-walled portion of the thin-walled recess is formed to have a thickness that allows the thin-walled portion to penetrate by pressing a screw screw.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described with reference to the drawings while comparing an embodiment according to the present invention with a conventional technique. 1 is a perspective view of a roof tile according to the present invention, FIG.
(A) is a cross-sectional view of a main part of the roof tile of the present invention, (b) is a cross-sectional view showing a state in which a screw is attached to the roof tile of the present invention, FIG. 3 (a) is a cross-sectional view of the main part of a conventional roof tile, and (b) is It is sectional drawing which shows the state which attached the screw to the conventional roof tile.

As shown in FIG. 1, the roof tile 1 according to this embodiment has the same basic outer shape as a so-called two-wave roof tile of a known roof tile. That is, mountain-shaped raised ridges 2a and 2b are formed in two places on the upper surface of the quadrangle, and the ridges 2a and 2b are formed.
Above (on the rear side 1a) and on the diagonal below (on the front side 1)
A pair of rectangular notches 3 and 4 are formed at the corners on the (c side).

[0007] On the surface of the roof tile 1, on the bottom 1a and on the flat side 1b, a draining ridge 5 is formed so as to project upward so as to prevent the rainwater from running up. further,
There is provided a nail hole recess 6 at one location in the vicinity of the drainage ridge 5 of the Tsutoge pass 2b and at one location on the front butt 1c side of the Tsutoge pass 2a.

FIG. 3 shows a conventional roof tile and its mounting state. In the figure, 12 is a roof tile, 61 is a recess for nail hole, 71 is a thin portion, 81 is a hidden hole, 9 is a screw screw, 10 is Rubber packing 11 is a washer. Conventional roof tile 12
In the mounting method of, the screw portion 9 is first attached to the thin portion 71.
A nominal hole for inserting is inserted in advance with a drill or the like, and a screw 9 is screwed into the nominal hole to be fixed. The roof tile 1 of the present invention shown in FIGS.
Compared with the conventional one, the hidden hole 8 is formed deeper to form the thin portion 7
Since it is made thinner, it is not necessary to hit the screw screw 9 with a hammer at first, and the screw screw 9
It is possible to penetrate by just loading, pressing and screwing,
Since it is unnecessary to pre-open the nominal hole as in the conventional case, a series of mounting operations can be performed quickly. Further, a ridge (lip) 6 formed on the periphery of the nail hole recess 6
The flat upper end surface of a and the washer 11 contact each other, and the recess 6 is completely closed. Further, since the recess 6 is formed to have a volume capable of completely accommodating the rubber packing 10, sufficient watertightness can be obtained.

In this embodiment, the roof tile 1 has a two-wave roof tile as a basic outer shape, but the present invention is not limited to this. For other types of roof tiles (Japanese-style, Western-style, flat-type, accessory, etc.), "the structure in which the ridge (lip) 6a is provided on the peripheral edge of the nail hole recess 6" It goes without saying that it is also applicable.

[0010]

As described above, the present invention has the following excellent effects. (1). Since the packing member is completely housed in the recess and is not exposed to the outside air, deterioration of the packing member can be prevented and high watertightness can be maintained for a long period of time. (2). Since the washer of the screw screw and the upper end of the ridge (lip) formed on the peripheral edge of the recess come into contact with each other and the recess is completely closed, high waterproofness can be obtained. (3). Since the concealed hole is formed deeper than the conventional product and the thin portion is made thinner, it is possible to penetrate by just screwing in the screwing machine and pressing it, and as in the past The work of opening the door is unnecessary, and a series of mounting operations can be performed quickly.
