Abstract

It is difficult to cope with a lateral shift in the direction of an overlap portion, and an engagement insertion portion is easily detached from an engagement protrusion.
An eaves-like engagement protrusion 9 is formed on the upper surface of the tile body 2 on the inner side of the tail-side water return 5 and an engagement insertion portion for the engagement protrusion 9 is formed in the head-side notch 6. 10 and the engagement insertion portion 10 are integrally formed on one or both of the roof tile body 2 and the underlap portion 4, and on the head side and the butt side,
The abutment surfaces 11 and 12 that face each other so as to come into contact with each other in the installed state are provided with the disaster prevention tile 1 above in the installed state
By forming so that the contact surface 11 of the disaster prevention roof tile 1 below is positioned on the overlap portion 4 side with respect to the contact surface 12, there is no lateral shift in the direction of the overlap portion 4. Furthermore, the engagement insertion part in the head side notch 6
10 is provided, the outer portion of the underlap portion 4 located outside the engagement portion is lowered even if the engagement protrusion 9 and the engagement insertion portion 10 are about to be swung up. Therefore, the engagement insertion portion 10 cannot be removed from the engagement protrusion 9 because it will not contact the lower disaster prevention roof tile 1 and rise further.

Description

The present invention relates to a disaster prevention tile capable of constructing a tile roof excellent in earthquake resistance, wind resistance and waterproofness.

In conventional disaster prevention tiles, an underlap part is projected from the other side of the tile body with an overlap part on one side. After placing it so that the overlap part of the disaster prevention tile to be overlapped, by inserting the nail into the nail hole formed on the bottom side and driving it into the roof base, repeatedly fixing it to the roof base, I try to crawl in a zigzag pattern.
However, in the above erected structure, the head side of the disaster prevention tile is not fixed, so the disaster prevention tile in the erected state rises up with the butt side as a fulcrum against the strong wind blowing from the lower side of the roof. In the end, there was a problem that had to be solved, such as the possibility that the nail would eventually come off or the roof tile would break and blow off.

Therefore, a hook-shaped engagement protrusion is formed on the upper surface of the butt side, and an engagement insertion portion for the engagement protrusion is formed on the head-side outer side portion of the underlap portion, and the upper portion of the engagement protrusion of the lower roof tile is formed. By inserting and inserting the engagement insertion part in the roof tile, the top side of the top roof tile is fixed to the bottom side of the bottom roof tile so that it does not rise from the head side even under strong winds. A roof tile was developed (see, for example, Patent Documents 1 to 3).

Japanese Patent No. 3407117 (Claims, FIGS. 10 to 14) Japanese Patent No. 3380235 (Claims, FIGS. 3 to 7) Japanese Patent No. 3601817 (Claims, FIGS. 1, 3, and 4)

However, the above prior art has a problem to be solved as described in the following (1) and (2).
(1) Since the engagement insertion portion is outside the underlap portion, the width of the engagement insertion portion is set to be narrow in order to secure the flow path width on the underlap portion as much as possible. Due to the shallow insertion of the engagement insertion part to the engagement protrusion, the pressure difference between the back of the tile caused by the wind blowing through the top surface of the roof tile in the event of a storm, When the roof tile itself vibrates and the roof tile gradually shifts from the specified position, it is possible to prevent the side shift in the direction of the underlap by the engagement protrusion of the adjacent roof tile. This is not possible, and the insertion is shallow, so that the engagement insertion portion is detached from the engagement protrusion.
(2) The tile in the erected state tends to roll up from the head side and the overlap part side around the engagement protrusion and the engagement part of the engagement insertion part, but the engagement insertion part is under Since it is located on the outer side of the wrap portion, the engagement insertion portion is easily detached from the engagement protrusion when the head side and the overlap portion side float.

In the present invention, in view of the above problem (1) based on the above prior art, the abutting surfaces facing the head side and the butt side so as to be able to come into contact with each other in the erected state are arranged so that the upper tile in the erected state contacts The bottom tile contact surface is located on the overlap side of the contact surface , and the bottom contact surface is
The side surface on the underlap side of the anti-slip protrusion provided on the surface and the contact surface on the head side
It can be a stepped surface formed at the boundary between the main body and the lower overlapping part, or it can be
On the side of the overlap part or the underside in the recess formed on the bottom of the roof tile
By using the inner surface on the side of the nip portion, the problem (1) is solved by preventing the displacement in the direction of the column and preventing the engagement insertion portion from being detached from the engagement protrusion.

Further, in view of the above problem (2), by providing an engagement insertion portion for the engagement protrusion in the head side notch, the engagement protrusion and the engagement portion of the engagement insertion portion are temporarily swung up. Even if it is going to be peeled off, the outer part of the underlap part located outside the engaging part is lowered and abuts against the lower tile so that it does not rise further, and the engaging insertion part does not come off from the engaging protrusion. Thus, the problem (2) is solved.

In short, according to the present invention, the abutting surfaces facing the head side and the tail side of the tile main body so as to come into contact with each other in the installed state are arranged so that the lower tile is placed on the overlap side from the contact surface of the upper tile in the installed state. Since the contact surface is formed so as to be positioned, even if the disaster prevention tile is about to shift in the direction of the spar with respect to the roof base, the displacement in the direction of the underlap is caused by the contact with the engagement protrusion of the adjacent disaster prevention tile. , Because the displacement in the direction of the overlap part can be prevented by the contact between the contact surfaces of both the upper and lower disaster prevention tiles, the lateral displacement due to the vibration of the tiles during storms and earthquakes can be prevented. It is possible to prevent the slipping off and maintain the seismic function, and thus it is possible to construct a tile roof having a high disaster prevention function with excellent wind resistance and seismic resistance.

A hook-shaped engagement protrusion is formed on the top side of the tile body on the inside of the bottom side water return, and an engagement insertion part for the engagement protrusion is provided on the head side from the head side end of the underlap part. Therefore, the head side of the disaster prevention tile in the erected state is fixed to the bottom side part fixed to the roof base of the disaster prevention tile below so that the head side of the disaster prevention tile does not rise even under strong winds Even if the disaster prevention roof tiles rise around the engaging part of the engaging protrusion and the engaging insertion part, the outer part of the underlap part located outside the engaging part is lowered and lowered. Because it touches the disaster prevention tile of
Since it can prevent that an engagement insertion part remove | deviates from an engagement protrusion, the roof provided with the wind-proof function can be constructed | assembled.
In addition, since the engaging projection is located on the inner side of the tail side water return, the lower disaster prevention roof tile exists below the engagement portion with the engagement insertion portion in the upper disaster prevention roof tile. Thus, it is possible to prevent rainwater and the like from entering the roof base side, thereby improving the waterproof function.
In addition, since the engagement insertion portion is provided on the head side from the head side end portion of the underlap portion, the head side portion of the flow path in the underlap portion does not become narrow even if the engagement insertion portion is present. Etc. does not get over the water return from the flow path, so that the waterproof function can be improved, and the thickness of the engagement plug can be set independently of the thickness of the underlap. The insertion part can be formed thicker than that formed on the outside of the underlap part as in the conventional case, so that the strength of the engagement insertion part can be improved, and it is possible to cope with a larger stress. I can do it.
In addition, since unexpected stress acting on the engagement plug does not act on the underlap portion, the underlap portion is not damaged by such stress, and it is possible to prevent water leakage due to this breakage. Can play a role in combating tread cracks.

Side surface on the underlap side of the anti-slip projection provided on the top side of the tile body with the head-side contact surface
And a step formed on the inner end side of the underlap portion on the lower surface of the tile body.
It can be a differential surface, a side surface on the overlap portion side of the convex portion formed on the bottom surface of the tile body,
Alternatively, since the inner surface of the underlap portion side of the concave portion formed on the bottom surface of the roof tile can be formed, a contact surface can be formed with a simple configuration. In particular, when the disaster prevention roof tile according to the present application is a flat roof tile, Since a stepped surface is inevitably formed at the boundary portion of the lap portion, a conventional mold can be processed and used without any major design change.
Furthermore, in the case of disaster prevention tiles where the contact surface is a stepped surface formed on the inner end side of the tile body and the underlap part, the disaster prevention tiles are installed as they are on the tile roof where the conventional flat roof tiles have dropped. However, since the engaging protrusion is housed in front of the underlap portion of the upper roof tile and the slip prevention protrusion is stored on the side of the step surface of the upper roof roof, compatibility with the conventional roof tile can be achieved. In addition, since the lateral displacement of the upper roof tile can be prevented by the engagement protrusion and the displacement prevention protrusion in the lower disaster prevention roof tile,
The disaster prevention function of existing tiled roofs can be slightly improved.

Since the outer part of the engagement plug part is positioned inward from the outer part of the underlap part, when the insertion part in the upper disaster prevention roof is inserted into the engagement protrusion in the lower disaster prevention roof and installed, The engaging protrusion of the lower disaster prevention tile in the installed state is located in front of the underlap portion of the upper disaster prevention tile and inward from the outer side of the underlap portion. Is set to a size that can be concealed, there is no need to make the width of the thin overlap part wider than necessary, and therefore the twisting and breakage rate of the overlap part during drying or firing is reduced and manufacturing is performed with good yield. I can do it.
In addition, since the width of the overlap portion can be accommodated if it is a size that can conceal the underlap portion, a general tile mold is repaired to form the engagement protrusion and the engagement insertion portion. Therefore, the manufacturing cost of the mold for the disaster prevention tile according to the present invention can be reduced, and the shape excluding the engagement protrusion and the engagement insertion portion is a conventional flat plate. Because it has the same shape as the tile and can be compatible with the conventional tile, the disaster prevention tile according to the present invention can be installed as it is on the tile roof where the conventional flat tile is dropped. The effect is great.

An embodiment of the present invention will be described below with reference to the drawings.
1 to 3 are a plan view, a front view, and an XX cross-section of the disaster prevention tile according to the present invention, and FIG. 4 is an enlarged view of a main part of the plan view showing the installation state of the disaster prevention tile of FIG. 5 is a cross-sectional view taken along line YY of FIG.
As shown in FIG. 4, the disaster prevention tile 1 according to the present invention is based on a flat roof tile that staggers on a roof base, and its basic structure is a plane as shown in FIGS. An overlap portion 3 is formed on one side of the tile body 2 having a substantially rectangular shape, an underlap portion 4 is formed on the other side, and a butt side water return 5 is formed along the outer edge of the butt side. In addition, a notch 6 is formed at a corner portion on the underlap portion 4 side, and a water return 7 is formed along the bottom side portion and the outer side portion of the underlap portion 4.

In the disaster prevention tile 1, the bottom side water return 5 is located near the center of the bottom side from the boundary line L of the polymerization site 8 on the bottom side.
On the inner side, that is, on the head side, a hook-shaped engagement protrusion 9 is formed which includes an upward projecting portion 9a and a lateral projecting portion 9b from the upper projecting portion 9a to the overlap portion 3 side. An engagement insertion portion 10 is provided in the notch 6, and the outer side portion of the engagement insertion portion 10 is positioned inward from the outer side portion of the underlap portion 4.
Further, the upper surface of the engagement insertion portion 10 is positioned below the upper surface of the underlap portion 4.

As shown in FIGS. 5 and 7 to 10 , the inner end portion of the engagement insertion portion 10 is headed from the head side end portion of the underlap portion 4 on the side surface of the roof tile body 2 on the underlap portion 4 side. In short, one or both of the roof tile main body 2 and the underlap portion 4 are formed integrally with the side portion, or the bottom end portion is integrally formed with the head end portion of the underlap portion 4 as shown in FIG. Are integrally formed.
In addition, the height H from the upper surface of the tile main body 2 of the engagement protrusion 9 is the height Ha from the upper surface of the tile main body 2 in the lower disaster prevention tile 1 in the installed state to the upper surface of the underlap portion 4 in the upper disaster prevention tile 1. It is preferable to set it lower. That is, the height H of the engagement protrusion 9 from the upper surface of the tile main body 2 is set so that the upper end portion of the engagement protrusion 9 of the lower disaster prevention tile 1 in the installed state is higher than the upper surface of the underlap portion 4 of the upper disaster prevention tile 1. It is preferable to set it so that it is located below.

On the bottom side and the head side of the tile main body 1 are provided contact surfaces 11 and 12 that face each other so as to come into contact with each other in the installed state. As shown in FIGS. 1 to 5 and 7 to 9, the provided abutting surface 11 is a side surface 13 a on the underlap portion side of the misalignment projection 13 provided on the top side of the tile body 1, and the other abutting surface. 12, that is, the contact surface 12 provided on the head side of the lower disaster prevention tile in the installed state is a step surface 15 formed at the boundary between the roof tile body 2 and the underlap 4 as shown in FIG. As shown in FIG. 8, the side surface 16a on the overlap portion 3 side of the convex portion 16 formed on the lower surface of the roof tile body 2, or as shown in FIG. 9, in the concave portion 17 formed on the lower surface of the roof tile body 2 The inner surface 17a on the underlap portion 4 side is used.
Further, the slip prevention protrusion 13 is formed on the top surface of the tail-side overlapping portion 8 of the roof tile body 2 and closer to the overlap portion 3 side than the engagement protrusion 9, preferably as close as possible to the engagement protrusion 9 and the installation work It is provided in a position that does not interfere with time.

In addition, although the disaster prevention tile 1 in the said Example is an object for staggering, it is not limited to this form, FIG.
As shown by 0 , an engagement protrusion 9 is provided on one side of the top surface of the bottom side polymerization site 8 of the roof tile body 2, that is, the top surface of the overlap portion 3, and the bottom side polymerization site 8 of the roof tile body 2 is shown. It is also possible to form a detent protrusion 13 on the other side of the upper surface, that is, the portion on the underlap 4 side for stroking.

Then, the engaging insertion portion 10 of the disaster prevention tile 1 to be installed is inserted into and engaged with the engagement protrusion 9 in the disaster prevention tile 1 provided on the roof base, or on the bottom side of the disaster prevention tile 1 below. Disaster prevention roof tile to be installed 1
After the head side of the roof is superposed shallowly, it is slid in the gradient direction, and the engagement insertion portion 10 is engaged with the engagement protrusion 9 of the disaster prevention tile 1 installed on the roof base from the bottom side, and then engaged under the roof. Placed on the ground,
When nails or the like are fixed to the roof base, a tiled roof constructed in a state where the head side of the upper disaster prevention tile 1 is fixed to the bottom side of the lower disaster prevention tile 1 is constructed.

Next, the operation of the disaster prevention tile according to the present invention will be described.
Since the head side of the disaster prevention tile 1 in the erected state is fixed to the disaster prevention tile 1 below, the head side does not lift up even under strong winds that blow up on the roof, does not cause slight movement, and the disaster prevention tiles on the top and bottom 1
The slipping contact surfaces 11 and 12 in FIG. 5 are in the proximity state or the contact state, so that the disaster prevention roof tile 1 in the installed state does not shift in the direction of the line.

Since the portion along the outer side of the water return 7 of the underlap portion 4 is linear and does not need to be bent to form the engagement insertion portion 10, the flow path in the underlap portion 4 is the head side. The rainwater flowing down on the flow path does not get over the water return 7 and enter the roof base side.
However, the rainwater or the like that has reached the head end of the underlap portion 4 may be positioned such that the upper end portion of the engaging insertion portion 10 in the lower disaster prevention roof tile 1 is located below the upper surface of the underlap portion 4. For example, without being blocked by the engagement insertion part 10, it flows down to the upper surface of the lower disaster prevention tile 1 and is discharged outside.
Moreover, even if the engagement insertion part 10 is lengthened and the profit margin of the disaster prevention roof tile 1 (the climbing length in the climbing direction) can be adjusted, the engagement portion with the engagement insertion section in the upper disaster prevention roof tile can be adjusted. Since the lower disaster prevention tile exists below, its waterproof function is maintained.

Since the engagement protrusion 9 is formed on the inner side of the butt side water return 5, the engagement protrusion 9 can be engaged closer to the head side than the conventional disaster prevention tile in which the engagement protrusion is formed on the butt side water return. Since the length from the engagement site to the head side end is shorter than the conventional disaster prevention tile, the moment in the length direction is reduced,
The load acting on the engagement portion is reduced, and as a result, the wind-resistant function of the tile roof is improved.
Furthermore, the engagement insertion part 10 is formed closer to the center side than the outer part of the underlap part 4, so that the disaster prevention roof tile is more resistant than the conventional disaster prevention tile in which the engagement insertion part is formed on the outer part of the underlap part. Because the moment in the width direction is reduced, the load acting on the engagement part is reduced, and even if the disaster prevention roof tile 1 tries to rise up around the engagement part. In addition, the outer portion of the underlap portion 4 is lowered in the opposite direction and comes into contact with the lower disaster prevention tile 1 so that the engagement insertion portion 10 does not come off from the engagement protrusion 9, and as a result, the wind resistance function of the tile roof is improved. It is done.
