Abstract

PURPOSE:To prevent definitely rain water from falling down to a sheathing roof board over the end on a ridge side by constituting an offset part formed on the end of a roof tile on a ridge side with a first offset part and a second offset part higher than the first offset part. CONSTITUTION:A connected overlapping unit 3 is continuously formed on the end of one of two flat board-shaped main bodies 2 on both sides forming an offset part at least on a ridge side. The offset part 22 comprises a first offset part 221 formed at a higher level than the surface of the flat board shaped-main body on a ridge side end and a second offset part 222 formed at a further higher level. As a result, even when rain water is pushed up to the ridge side from an eave side running along the surface of roof tiles 1, the rain water is collided against the first offset part 221 and damped. Even if the rainy water is collided against the second offset part beyond the first offset part 221, the rainy water is collided against the second offset part and further damped, which makes it possible to prevent the rainy water from flowing down to a roof sheathing board over a ridge side end of the roof tiles 1.

Embodiments of the present invention will be described below with reference to the drawings.

1 to 6 show a roof tile 1 of the present invention, which is a flat plate-shaped main body 2 and a connection formed continuously from the left end edge of the flat plate-shaped main body 2. The flat plate-shaped main body 2 includes a stacking portion 3, and a left platform 21, a terrace 22, and a right platform 23 are formed on the left side, the ridge side, and the right side of the surface of the flat plate-shaped main body 2, respectively. Further, the eaves side of the front surface of the flat plate-shaped main body 2 is formed in a gentle downward slope, and its edge is vertically cut off to form a leg portion 24 having a height exceeding the back surface thereof.

Further, in the substantially central portion of the surface of the flat plate-shaped main body 2, there is formed a rain escape portion 25 having a predetermined lateral width slightly higher than the surface from the ridge side to the vicinity of the eaves side edge. On the ridge side of the rain escape portion 25, the flat plate-shaped main body 2
Islands 26, 26, which are slightly higher than the surface of, are formed at intervals. A nail hole is penetrated from the front surface to the back surface of the island portion 26.

By the way, on the ridge side of the left trapezoidal portion 21 and the right trapezoidal portion 23 of the flat plate-shaped main body 2, roofing foot adjusting portions 21a and 23a each having a predetermined vertical length slightly lower than the surface thereof are formed. Therefore, when the roof tile 1 is laid, that is, when the other roof tile 1 is laid adjacent to the left side of the one roof tile 1, the other roof tile 1 is attached to the left edge of the flat plate-shaped main body 2 of the one roof tile 1. The right end edge of the flat plate-shaped main body 2 is joined to form a mountain with a substantially trapezoidal cross section by the left trapezoidal portion 21 of one roof tile 1 and the right trapezoidal portion 23 of another roof tile 1 and at the same time, on the ridge side thereof. , Thatched roof adjusting part 21a of one roof tile 1 and thatched roof adjusting part 2 of another roof tile 1
3a is continuous in the left-right direction. The vertical lengths of the thatched foot adjusting portions 21a, 23a are formed to be larger than the vertical length of the bottom surface of the leg portion 24, and the leg portion 24 is placed while being adjusted in the ridge direction or the eaves side direction within this range. be able to.

On the rear surface side of the right platform 23, there is formed a space for accommodating a connection overlapping portion 3 described later (see FIG. 6), and a ridge side corner portion thereof is cut out, When the roof tiles 1 and 1 are laid, the cutout portion and the ridge-side corner portion of the connection overlapping portion 3 do not interfere with each other. Furthermore, leg 2
As described above, when the roof tiles 1 and 1 are laid, the substantially central portion of the roof tile 4 has a left trapezoidal portion 21 of one roof tile 1 and a right trapezoidal portion 23 of another roof tile 1.
And are cut out corresponding to the trapezoidal cross section formed by joining and.

The terrace 22 is formed to be slightly higher than the first terrace 221 which is slightly higher than the surface of the flat plate-shaped main body 2 toward the ridge side edge. It consists of the second terrace 222, and the second terrace 22
In addition to the recesses 22a, 22a having a trapezoidal cross section, are formed at a distance from each other on the back surface 2, and the above-described recesses 22 are provided on the back surface thereof.
Protrusions 22b, 22b having a trapezoidal cross section corresponding to the concave portion 22a are formed at positions corresponding to a (see FIG. 3). Then, the bottom surface of the convex portion 22b and the bottom surface of the leg 24 described above are formed so as to be located on substantially the same plane, as shown in FIG.

As a result, even if the rainwater is pushed up from the eaves side to the ridge side along the surface of the tile 1 by the strong wind, the terrace portion 22 of the two-tiered structure crosses the edge of the tile 1 on the ridge side. It can be surely prevented from flowing to the ground plane.
That is, the rainwater pushed up along the surface of the roof tile 1 is
First, the first terrace part 221 is collided and the momentum is attenuated.
Then, even if the damped rainwater passes over the first terrace 221 and collides with the second terrace 222 formed higher than the first terrace 221, the momentum is further attenuated,
Rainwater does not flow over the roof tiles beyond the roof tile edge. Further, when a plurality of roof tiles 1 are stacked, one roof tile 1 has a concave portion 22a and another roof tile 1 has a convex portion 22a to be stacked thereon.
b can be engaged with each other and both can be reliably held in a substantially horizontal state.

On the other hand, the connection overlapping portion 3 has its width and length set in correspondence with the space formed on the back surface of the above-mentioned right platform 23, and its left end edge and ridge side end edge are A built-up portion 31 is formed slightly higher than the surface.
As a result, even if rainwater enters from the joining portion of the pair of adjacent roof tiles 1 and 1, it flows along the surface thereof from the ridge side to the eaves side and does not cross over the built-up portion 31.

Next, a case of using the roof tile 1 to roof a roof will be described with reference to FIG.

First, one roof tile 1 is arranged at the lower right, and a nail is inserted through the nail hole and fixed to a field plate (not shown). Then, adjacent to the left side of the one roof tile 1 on the connecting overlapping portion 3,
The right trapezoidal portion 23 of the flat plate-shaped body 2 of the other roof tile 1 is placed so as to be positioned, and the left end edge of the flat plate-shaped body 2 of one roof tile 1 is attached to the right end edge of the flat plate-shaped body 2 of the other roof tile 1. Are joined together to form a mountain with a trapezoidal cross section by the left trapezoidal portion 21 and the right trapezoidal portion 23 over one roof tile 1 and the other roof tile 1. At this time, the right trapezoidal portion 23 of the flat plate-shaped main body 2 in the roof tile 1
Since the ridge-side corner portion of the ridge is notched, it does not interfere with the ridge-side corner portion of the connection stack portion 3 of the one roof tile 1. Next, the other roof tiles 1 are nailed and fixed, and the other roof tiles 1 are sequentially arranged on the left side of the one roof tile 1 and fixed in the same manner.

When the tiles 1 are laid in one row in this way, the tiles 1 in the second row are laid on the ridge side. In particular,
A pair of roof tiles 1, 1 in which the central cutout portion of the leg portion 24 is laid on the eaves side is provided on the pair of roof tiles 1, 1 that are fixed in advance and adjacent to each other. The legs 24 are arranged so that the bottom surfaces of the legs 24 are located at the thatched-foot adjusting portions 21a and 23a while straddling the trapezoidal cross section formed by the left trapezoidal portion 21 and the right trapezoidal portion 23. Fix by striking. At this time, one roof tile to be placed on the ridge side is connected to the roofing foot adjusting portions 21a and 23a that are continuous by joining the left trapezoidal portion 21 and the right trapezoidal portion 23 of the pair of roof tiles 1 and 1 laid on the eaves side. 1. Position the leg portion 24 of No. 1 and thatched foot adjusting portions 21a, 2
By shifting in the flow direction of the roof within the range of 3a, thatch, that is, the stacking can be adjusted. As a result, even if the size of the roof changes, it can be dealt with by adjusting the stacking of the roof tiles 1.

In the same manner, another roof tile 1 is placed on the left of one roof tile 1 in the same manner.
A pair of roof tiles 1, in which the right trapezoidal portion 23 is placed on the connecting overlapping portion 3 of one roof tile 1 so that the central cutout portion of the leg 24 of the other roof tile 1 is laid on the eaves side 1, It is arranged such that the bottom surface of the leg portion 24 is located at the thatched foot adjusting portions 21a and 23a at the same time as straddling a mountain having a trapezoidal cross section formed by the left trapezoidal portion 21 and the right trapezoidal portion 23. Fix it with nails. Next, another roof tile 1 may be sequentially arranged and fixed on the left side of the roof tile to form a roof tile row, and then a roof tile row may be similarly formed on the ridge side.

When the tile roof is roofed in this way, the tile 1
The rainwater that separates left and right by the rain escape portion 25 formed in the flat plate-shaped main body 2 in the above, and the rain escape portion 25 formed in the flat plate-shaped main body 2 in the roof tile 1 arranged on the eaves side thereof.
Will be led to one side. That is, the rainwater flowing on the left side of the rain escape portion 25 of one roof tile 1 flows on the right side of the rain escape portion 25 of the roof tile 1 located on the eaves side, and then flows down while maintaining the divided state. As a result, the rainwater does not join at the center of the flat plate-shaped main body 2 and can be gently led to the rain gutter with a flow rate that is half that of the combined case. Therefore, even if rainwater is pushed up toward the ridge by a strong wind, the rainwater that has entered the overlapping portion of the roof tile 1 due to the small flow rate of the roof tile 1
It is possible to prevent it from flowing over the ridge-side edge of the building and flowing into the field board.

In this embodiment, the connecting and overlapping portion 3
Although the roof tile 1 continuously formed on the left side edge of the flat plate-like body 2 is illustrated, it may be formed on the right side edge of the flat plate-like body 2.
In this case, it is necessary to form a space on the back surface side of the left trapezoidal portion 21 in which the connection overlapping portion 3 can be accommodated.

[0022]

As described above, according to the present invention, a flat plate-like main body having a terrace portion formed at least on the ridge side, and a connecting overlapping portion continuously formed on the left and right side edges of the flat plate-like main body The terrace includes a first terrace formed higher than the surface of the flat plate-shaped main body toward the ridge-side edge, and the first terrace.
Since it is composed of the second terrace that is formed higher than the terrace, even if rainwater is pushed up from the eaves side to the ridge side by the strong wind along the surface of the tiles, the rainwater is still in the first terrace and the second terrace. Since the parts collide in order and are damped, it is possible to reliably prevent rainwater from flowing over the edge of the roof tiles on the ridge side and flowing down to the ground plate.
