Description

  The present invention relates to a roof tile.

Conventionally, the following tiles are installed on the roof of a building such as a house.
As shown in FIG. 10, the roof tile 110 has a substantially flat roof tile body 120, a lower overlapping portion 130 is provided on the left side thereof, and an upper overlapping portion 140 is provided on the right side thereof. .
In addition, a pair of downward projecting portions 128 are formed at the ridge side end of the back surface of the roof tile body 120. Each downward protruding portion 128 protrudes on the back side of the tile main body 120. A nail hole 129 is formed in the vicinity of the ridge side end of the tile body 120.

The tiles 110 are installed on the roof as follows.
First, as shown in FIG. 11 (a), the roof tile B is fixed to the roof plate P. The roof tile B is provided for each row in which the roof tile 110 is installed (the direction corresponding to the left and right direction of the roof tile 110 is referred to as “row”).
That is, in the direction between the eaves side and the ridge side of the roof plate P (hereinafter also referred to as the eaves ridge direction), the number of roof tiles B corresponding to the number of rows of tiles 110 installed on the roof is attached.
In addition, a support material (not shown) is fixed to the roof plate P corresponding to the most eave-side tile row (in the vicinity of the eave-side end portion). This support material is for maintaining the roof-side roof tile at a predetermined inclination angle.

And as shown in FIG.11 (b), each tile 110 is gravity-supported with respect to the roof board P by being latched by the tile rail B in the downward protrusion part 128. As shown in FIG. Further, the tiles 110 are fixed by appropriately hitting the nails against the roof rails B through the nail hole portions 129.
In this way, each roof tile 110 is provided with the upper overlapping portion 140 superimposed on the lower overlapping portion 130 in the left-right direction. Further, in the eave building direction, the adjacent tiles 110 in the eave building direction are shifted in the left-right direction by about half the width of the roof tile 110 so that the ridge is located on the ridge side edge of the eaves side tile 110. The eaves side edge of the roof tile 110 on the side is overlaid.

As described above, in the conventional roof tile 110, the downward protrusion 128 is locked to the roof bar B and is supported gravitationally.
For this reason, in order for the above-described conventional tile 110 to be installed, it is necessary to attach the tile rail B to the roof plate P for each row.
However, if the roof rail B is attached to each row, the efficiency of the tile laying work is reduced, and the cost increases accordingly.

  Then, this invention makes it a subject to provide the roof tile which can be installed efficiently.

  In order to solve the above-described problem, the invention according to claim 1 is directed to a roof body having a lower overlapping portion on one of the left and right edges and an upper overlapping portion on the other side, and a back surface of the roof body. An abutting portion protruding on the back side of the tile body, and the abutting portion abuts against the tile adjacent to the eave side when installed, thereby at least part of the weight of the tile Is a roof tile that is supported by a roof tile adjacent to the eaves side.

  The phrase “abuts against the roof tile adjacent to the eave side when installed,” includes the case of contacting the ridge side end (including the end face) of the tile adjacent to the eave side. That is, the end face on the ridge side may be a contacted part. In addition, a contacted portion may be separately formed in a portion other than the end surface on the ridge side in the ridge side end portion. Moreover, it may correspond to both of them. Here, the “end surface on the ridge side” refers to a surface connecting the front surface and the back surface of the tile at the end portion on the ridge side of the tile.

In the roof tile according to the present invention, a description will be given by focusing on one roof tile (hereinafter referred to as the roof tile) (the same applies hereinafter), and an upper overlapping portion of the roof tile is superimposed on a lower overlapping portion of the roof tile adjacent in the left-right direction. The eaves side edge of the tile is superimposed on the ridge side edge of the tile adjacent to the eave side.
In the roof tile according to the present invention, the contact portion of the roof tile abuts against the roof tile adjacent to the eaves side, and at least a part of the weight of the roof tile is supported by the roof tile adjacent to the eaves side.
For this reason, in the tile according to the present invention, it is not necessary to provide tile rails corresponding to each row of tiles on the roof plate (that is, the number of tile rails is smaller than the number of tiles installed on the roof). The efficiency of the work of laying tiles on the roofing board is improved.

  Moreover, since the contact part protrudes in the back surface of the said tile main body in the back surface of a tile main body, when the said tile is installed, a contact part is not visually recognized by a viewer. For this reason, the above-mentioned effect can be acquired without impairing aesthetics.

  The invention according to claim 2 is the roof tile of the invention according to claim 1, wherein the roof tile main body or the upper stacking at the end of the front surface of the roof main body or the upper overlapping section or the vicinity thereof. A protruding abutting portion that protrudes to the front side of the portion, and the abutting portion abuts against the protruding abutting portion of the tile adjacent to the eaves side when installed. There is a tile.

That is, when the present invention is described independently, it is as follows.
“A tile body having a lower overlapping portion on one of the left and right edges and an upper overlapping portion on the other;
A contact portion projecting to the back side of the tile body on the back surface of the tile body;
A projecting contact portion projecting to the front side of the tile main body or the upper overlapping part at or near the ridge side end of the front surface of the tile main body or the upper overlapping part,
The abutting portion abuts against the protruding abutting portion of the tile adjacent to the eave side when installed, so that at least a part of the weight of the tile is adjacent to the eave side. Is to be supported,
tile. "

“It has a protruding abutting portion that protrudes to the front side of the tile main body or the upper overlapping portion at or near the edge of the ridge side of the front surface of the tile main body or the upper overlapping portion,” The case includes a case where the roof main body or the upper overlapping portion has a protruding contacted portion that protrudes to the front side of the roof main body or the upper overlapping portion at the ridge side end of the front surface.
And particularly in that case, “the abutment portion abuts against the protruding abutting portion of the tile adjacent to the eaves side when installed,” For both the case where the abutting part abuts only on the protruding abutting part of the adjacent roof tile and the end face on the ridge side and the protruding abutting part of the roof tile (the tile main body or the upper overlapping part) adjacent to the eaves side. On the other hand, there is a case where the abutting portion abuts (that is, the end surface on the ridge side is also the abutted portion).

In the roof tile of the present invention, in addition to the functions and effects of the roof tile of the invention according to claim 1, the following functions and effects are obtained.
That is, in the tile of the present invention, the protruding contact portion protrudes to the front side of the tile main body or the upper overlapped portion, and the tile contact with the protruding contact portion of the tile adjacent to the eaves side. The parts abut. For this reason, compared with the case where the abutted portion does not protrude to the front side of the tile main body or the upper overlapping portion and abuts against the end surface of the tile adjacent to the eave side, the abutting portion is the tile. Even if the degree of protrusion protruding to the back side of the main body is small, it can contact the tile (contacted portion) adjacent to the eaves side.
For this reason, in this invention, the protrusion degree of a contact part may be small by that much, manufacture of a roof tile is easy, and the intensity | strength of a roof tile is kept high.

  The invention according to claim 3 is the roof tile of the invention according to claim 1 or claim 2, wherein the front surface of the roof tile main body has a front surface of the roof tile body at or near the center in the left-right direction.

Next, a method for installing the roof tile 10 and its function and effect will be described.
As shown in FIG. 5, first, a roof rail B is fixed to the roof plate P. The roof tile B is a rod-shaped wood having a square cross section, and is attached so as to extend along the left-right direction (row direction) of the roof tile 10.
The roof tile B is provided corresponding to the row of the roof tiles 10 on the eaves side (the end of the ridge side). In addition, as shown by a two-dot chain line in FIG. 5, the tile rail B may be provided as appropriate in the middle of the roof board P in the eaves-ridge direction.
Moreover, as shown in FIG. 6, the support material S is fixed to the roof board P corresponding to the row of the roof tiles 10 on the most eaves side (near the end of the eaves side) (illustrated in FIG. 5). (Omitted). The support material S has a rod shape having a substantially triangular cross section.

Then, as shown in FIG. 6, in the row where the roof tile B is provided (for example, the row on the most eaves side), the roof tile 10 has the downward projecting portion 28 locked to the roof tile B, and if necessary. Thus, the nail is fixed to the roof bar B by being struck against the roof bar B through the nail hole 29 as appropriate.
Further, the support material S keeps the roof-side roof tile 10 at a predetermined inclination angle.

As shown in FIGS. 7 and 8, the tiles 10 are erected in order from the right to the left with respect to the roof, and are erected in order from the eaves side to the ridge side.
That is, after the roof is erected in order from the right end to the left end in the most eave side portion, the ridge side is erected in order from the right end to the left end. At that time, the tiles 10 adjacent in the eave building direction are installed so as to be shifted by about half the width of the tile 10 in the left-right direction. The same is set up in the following manner.

  Based on FIGS. 7-9, the 1st roof tile 10A-the 5th roof tile 10E are demonstrated in detail. A certain roof tile 10 is referred to as a first roof tile 10A, adjacent to the ridge side of the first roof tile 10A (that is, located in a row on the one wing side), and the right roof tile 10 among the roof tiles 10 adjacent to each other on the left and right. Is called the second roof tile 10B (FIGS. 7 and 8), and the left roof tile 10 is called the third roof tile 10C (FIG. 8). Further, the tile 10 on the right side of the first roof tile 10A located in the same row as the first roof tile 10A is referred to as a fourth roof tile 10D (FIG. 7), and the roof tile 10 on the left side is referred to as a fifth roof tile 10E (FIG. 8). .

First, as shown in FIG. 7, the second roof tile 10B is installed on the first roof tile 10A and the fourth roof tile 10D.
At that time, the upper overlapping portion 40 of the first roof tile 10A is fitted to the fitted portion 23 of the second roof tile 10B.
Further, the eaves side edge (hereinafter also referred to as eaves side edge) of the second roof tile 10B is on the ridge side edge (hereinafter also referred to as ridge side edge) of the first roof tile 10A and the fourth roof tile 10D. To overlap.
And as shown in FIG. 9, the contact part 26 of the 2nd roof tile 10B is made to contact | abut to the protrusion contacted part 46 of 10 A of 1st roof tiles. In this way, the weight (part) of the second roof tile 10B is supported by the first roof tile 10A.

Next, as shown in FIGS. 8 and 9, a third roof tile 10C is installed on the first roof tile 10A, the second roof tile 10B, and the fifth roof tile 10E.
The upper overlapping portion 40 of the third roof tile 10C is overlaid on the lower overlapping portion 30 of the second roof tile 10B, and the eaves side edge of the third roof tile 10C is the ridge side edge of the first roof tile 10A and the fifth roof tile 10E. Overlay on top.

By repeating the above operations, a large number of tiles 10 are installed on the roof.
And by changing the way of viewing, in principle, all the tiles 10 (except for the edge portion) correspond to the first tile 10A to the fifth tile 10E.

With the roof tile 10, the following effects can be obtained.
As described above with reference to FIG. 9, the abutment portion 26 of the roof tile 10 (second roof tile 10B, third roof tile 10C) protrudes from the roof tile 10 (first roof tile 10A, fifth roof tile 10E). The abutment-side roof tile 10 is in contact with the weight of the roof-side roof tile 10 (part thereof).
For this reason, as shown in FIGS. 5 and 6, in principle, it is not necessary to provide the roof rail B for each row of the roof tiles 10.

However, as shown in FIGS. 5 and 6, the tile rail B corresponding to the most eave-side row is necessary, and in principle, all the tiles 10 on the ridge side of the tile rail B are used by the tile rail B. Weight is supported.
Moreover, when the number of rows of the tiles 10 is large, as described above, the tile rails B are also appropriately provided in the middle part in the eaves ridge direction (indicated by a two-dot chain line in FIG. 5). Then, the tile rail B supports the gravity of the roof tile 10 on the ridge side with respect to the tile rail B, so that the burden on the tile rail B on the eaves side of the tile rail B is reduced.

  Thus, in this tile 10, it is possible to greatly reduce the number of tile bars B provided on the roof plate P, and the efficiency of the work of installing the tile 10 on the roof plate P is greatly improved.

In addition, this roof tile 10 also provides the following effects.
As shown in FIG. 8, the upper overlapping portion 40 of the third roof tile 10 </ b> C may be lifted by a strong wind or the like because the engaging portion 52 of the first roof tile 10 </ b> A is engaged with the engaged portion 42. Is prevented. Since the lower overlapping portion 30 of the second roof tile 10B overlaps the upper overlapping portion 40 of the third roof tile 10C, it is prevented from rising due to the strong wind or the like due to its gravity. Thus, the roof tile 10 is prevented from being lifted by a strong wind or the like.

Further, since the engaging portion 52 of the first roof tile is engaged with the engaged portion 42 of the third roof tile 10C, the displacement of the third roof tile 10C is prevented.
That is, as described above with reference to FIG. 9, the third roof tile 10 </ b> C comes into contact with the fifth roof tile 10 </ b> E (its protruding contacted portion 46) at its contact portion 26 and is supported by weight, The movement in the direction is blocked (however, the rotation of the third roof tile 10C around the contact portion 26 is not blocked). At the same time, as shown in FIG. 8, the rotation of the engaged portion 42 is prevented, thereby preventing the position of the third roof tile 10C from shifting.
In this way, displacement of the roof tile 10 is prevented.

  Further, in the roof tile 10, the following effects are obtained by the water flow guide portion 50. As shown in FIG. 7, the adjacent roof tiles 10 in the eave building direction are installed so as to be shifted by about half the width of the roof tiles 10 in the left-right direction, whereby the water flow guide portion 50 of the second roof tile 10B. However, the upper overlapping portion 40 of the first roof tile 10A overlaps the portion where the two roof tiles 10A and 10D adjacent to the eaves overlap (that is, the lower overlapping portion 30 (not indicated in FIG. 7) of the fourth roof tile 10D. Part). In such a positional relationship, rainwater or the like flowing on the second roof tile 10B flows in a portion of the roof tile body 20 other than the water flow guide portion 50 in the eaves side direction. Then, the first roof tile 10A and the fourth roof tile 10D overlap each other in the first roof tile 10A and the fourth roof tile 10D by being guided by the portion in the vicinity of the eaves-side end portion of the water flow guide portion 50 whose width is widened to the left and right. Flow to avoid parts. For this reason, the rainwater or the like is prevented from entering the inside (below the first roof tile 10A and the fourth roof tile 10D) from the overlapping portion.

Note that the above is merely an embodiment of the present invention, and it is needless to say that the present invention can be implemented in various modifications based on the knowledge of those skilled in the art.
For example, the protruding portion 45 (the protruding engaged portion 46) is not necessarily provided, and the contact portion 26 may contact the end surface 41 on the ridge side of the upper overlapping portion 40 (that is, on the ridge side). The end surface 41 becomes a contacted portion).
Further, the degree of protrusion of the protrusion 25 (the contact part 26) is further increased so that the contact part 26 is applied over both the protrusion engaged part 46 of the protrusion 45 and the ridge side end face 41 of the upper overlapping part 40. It may be a dimensional relationship that touches.
