Description

  The present invention relates to an improvement in the wind-resistant structure of clay tiles that are sown at the front end portion of the eaves at the time of lifting.

  In the case of a flat roof tile, for example, a slate-based flat tile, Patent Document 1 proposes a windproof clip for eaves tile as a method for firmly fixing the eaves tile to a base material. In this clip, the end of a belt-like substrate 10a as shown in FIG. 4 (perspective view) is formed in a T shape, and one end thereof is a hook 10b that can be engaged with an eaves starter (not shown), and the other end. Is a hook 10c that can be engaged with the tip of an eaves tile (not shown).

  In the construction of the eaves, the eaves starter and the hook 10b are engaged, fixed to the base with a nail or the like, and then the eaves tile is installed with its tip engaged with the hook 10c. It is possible to fix the eaves tile without drilling a fixing hole or nailing. Although such a wind-resistant clip can be applied to clay roof tiles, there is a problem that the wind-resistant clip is exposed at the eaves, which is not preferable in terms of appearance.

  As a method for firmly fixing the eaves tile to the base material without exposing the clip, Patent Document 2 proposes an eaves tile fixing clip. According to FIG. 5 which is a perspective view of the clip, the clip 11 is composed of a base plate 11b provided with a claw 11a at the peripheral portion, a column plate 11c, and a presser plate 11e provided with a hooking portion 11d at the tip. .

  This clip 11 is used as shown in FIG. That is, the base plate 11b is pierced into the roof base material 13 with the nail 11a while temporarily pressing the holding plate 11e against the upper surface of the underlap 12a of the eaves tile 12. Then, if the base plate 11b is fixed to the roof base material 13 with a nail or a screw (13a), it is possible to efficiently perform the laying operation for firmly fixing a series of eaves tiles.

  In this case, since the clip 11 is covered with the eaves tiles adjacent to each other, there is an advantage that the clip 11 is not exposed to the outside. However, there is a disadvantage in that it is necessary to prepare and place a dedicated eaves tile fixing clip in advance, which increases costs.

  As an eaves tile fixing means that can be relatively easily performed, an inverted L-shaped bracket called an L nail (14) as shown in FIG. 7 is generally used. When laying the eaves tile 12, as shown in FIG. 7 (a), an L nail 14 is driven into the base material, for example, a wide and small dance, using a hammer along the underlap 12a. As shown in FIG. 5, the eaves tile can be firmly fixed to the ground by engaging the engagement bent portion 14a of the L nail 14 with the underlap 12a.

  In such a method using the L nail 14, there is a problem such as damage to the underlap 12 a if a hammer operation is mistaken, and skillful techniques are required, and the L nail 14 is deformed abnormally. There is also a problem of increased cost because the fixing strength cannot be obtained or it is not a general-purpose metal fitting.

  Furthermore, as a disaster prevention tile with improved wind resistance performance, an engagement protrusion (hook) is formed on the top surface of the bottom of the tile, and the side end portion of the underlap of the tile placed on the upper side is arranged on the lower side when lifting up There is a clay roof tile that is inserted below the engagement protrusion of the roof tile and has a wind-resistant structure in which the top and bottom roof tiles are engaged. In the case of this type of disaster prevention tile, when used as an eaves tile, there is no tile placed on the lower side, so the tile placed on the eave is fixed to the base material by the various methods described above. It was necessary and included the problems mentioned above.

  In addition, in the case of this type of disaster prevention tile, if the engagement protrusion is damaged for some reason in a use form other than the eaves tile, reinforcement is performed by adhering and fixing to the base material using a silicon-based adhesive. However, there is a problem that the reinforcing strength or durability varies, and there has been a demand for improvement as in the case of using the eaves.

(1) Japanese Patent Laid-Open No. 8-114006: Paragraph (0000), FIG.
(2) Japanese Patent Application Laid-Open No. 2004-84426: Claims, FIGS. 1 and 2

  The present invention has been made to solve the above-described problems, and avoids damage to the underlap without using a special clip or the like in addition to the L nail, and the base material for the eaves tile at a low cost. A disaster prevention roof tile that realizes stable fixing to the windshield and enables reliable reinforcement when the engagement projection is damaged in the case of a wind-resistant roof tile due to the engagement between the side end portion of the underlap and the engagement projection. provide.

When the above problem is used as an eaves tile in a portion of the clay roof tile formed with an underlap on one side and an overlap on the other side, near the head of the water return disposed on the underlap. The hole can be opened and used, and it can be firmly fixed to the base material with a metal fitting such as a simple nail or screw. The surface is closed when the hole is not used, such as in applications other than eaves tiles. The problem can be solved by the disaster prevention tile according to the present invention, which is provided with a hidden fixing hole.

  Further, according to the present invention, the clay tile forms an engaging projection on the top surface of the bottom portion, and when the tile is rolled up, the engaging projection of the tile arranged on the lower side is formed on the engaging portion of the tile arranged on the upper side. It can preferably be embodied in a form that is a clay roof tile having a wind-resistant structure in which the upper and lower roof tiles are engaged and constitute an engaged state.

  When the disaster prevention tile according to the present invention is used as an eaves tile, it can be firmly fixed to a base material with a metal fitting such as a simple nail or a screw by using the hidden fixing hole. And since the fixing work is also a simple nailing or screwing operation, no special experience is required for the work, and the roof tile is not damaged. In addition, the fixing nails and screws used in the present invention can be applied to general-purpose hardware, which is advantageous in terms of cost. Since it is covered by the wrap, there is also an advantage that it does not cause an appearance defect.

  In addition, when the disaster prevention tile of the present invention does not use the concealed fixing holes, such as in the case of uses other than the eaves tile, the surface of the portion is closed, so there is no risk of water leakage toward the base material. Furthermore, the disaster prevention tile of the present invention can be firmly fixed to the base material by using these concealment fixing holes as required, even in the case of uses other than eaves tiles.

  Further, the disaster prevention roof tile of the present invention forms an engagement protrusion on the upper surface of the bottom part, and when the roof is raised, the engagement protrusion of the roof tile arranged on the lower side is engaged with the engagement section of the roof tile arranged on the upper side. In the case where the upper and lower roof tiles have a wind-resistant structure that constitutes the engaged state, if the engagement protrusion is damaged for some reason, the roof tiles are individually grounded using the hidden fixing holes in this way. Therefore, there is an advantage that wind resistance can be maintained for a long period of time as compared with a repair method such as an adhesive. Therefore, the present invention has an extremely large industrial value as a disaster prevention tile that has solved the conventional problems.

Next, Embodiments 1 and 2 according to the disaster prevention roof tile of the present invention will be described with reference to FIGS.
(Embodiment 1)
The disaster prevention tile of the present invention, when used as an eaves tile, can be firmly fixed to a base material using fixing nails and screws that are general-purpose hardware. Specifically, as shown in FIG. 1, in a clay roof tile 2 in which an underlap 21 is formed on one side surface and an overlap (not shown) is formed on the other side surface, a bank-shaped water disposed on the underlap 21 is provided. A fixing screw 31 is screwed into a fixing hole 23 provided in a portion close to the head of the barb 22 and can be fixed to the base material 41 of the roof.

  The feature of the present invention is that the fixing hole 23 for screwing the fixing screw 31 is a hidden fixing hole covering the surface as shown in FIG. That is, as shown in FIG. 2A, the fixing hole 23 is not exposed on the front surface before use, but as shown in FIG. By perforating and leaving a thin portion with a thickness that does not penetrate, a hidden fixing hole with a closed surface can be obtained. In this case, an opening 23b is formed on the back surface.

Such a hidden fixing hole may be perforated by press-fitting a pin having a diameter of 3 to 6 mm from the back surface during press molding of the tile fabric or after molding and leaving a thin portion so as not to penetrate. When using the hidden fixing hole, the thin-walled portion is set to a thickness that can be easily opened and opened as a fixing hole 23 with a sharp impact on the surface with a hammer or the like having a sharp point. Yes. This thickness is preferably 3 mm or less.
If this thin portion is not provided, liquid glaze will flow in the subsequent glazing process and close the hole, so that it becomes impossible to open the hole when necessary. Conditions must be well managed.

Then, when it is used as an eaves tile, if a light impact is applied with a hammer having a sharp point on the thin wall portion, as shown in FIG. 2 (c), a fixing screw 31 for screwing in is fixed. The hole 23 can be opened, and as shown in FIG. 1, the fixing screw 31 can be screwed to be fixed to the roof base material 41.
In addition, as shown in FIG. 2, in order to reinforce the intensity | strength of the part of the bank-shaped water return 22 which provided the hidden fixing hole, it is good to form the part wide.

  Here, the fixing screw 31 has been described as the fixing bracket, but this may be a fixing nail, and the disaster prevention tile of the present invention is firmly attached to the base material with such a simple nail or screw. In addition, since the operation is simple nailing or screwing, even an inexperienced worker can do it without damaging the roof tile. In addition, in the present invention, since a general-purpose hardware can be applied, it is inexpensive and the screw head after fixing is hidden by the adjacent roof tile, which is preferable in terms of appearance.

  In addition, the disaster prevention tile of the present invention, such as in the case of uses other than the eaves tile, even when not using these concealed fixing holes, the surface of the part is closed, so water leaks toward the base material. There is no fear. Furthermore, even in the case of uses other than eaves tiles, the tiles can be firmly fixed to the base material using concealment fixing holes as necessary.

(Embodiment 2)
The present invention can be more preferably embodied in the case of a disaster prevention tile as shown in FIG.
That is, the engagement protrusion 25 is formed on the upper surface of the bottom of the clay roof tile 2 shown in FIG. 3 (a), and the side end portion 23 of the underlap of the roof tile arranged on the upper side is arranged on the lower side when the clay roof 2 is rolled up. This is a case of a disaster prevention clay roof tile having a wind-resistant structure in which the top and bottom roof tiles are engaged by being inserted below the front end portion of the engagement protrusion 25 of the roof tile.
In addition, although the case of straight-rolling is illustrated and described here, it goes without saying that the present invention can be similarly applied to staggered-rolling. The same applies to Embodiments 3 and 4 described later.

In this disaster prevention roof tile, if for some reason it is damaged and lost in the engagement protrusion 25 (see FIG. 3 (b)), since the engagement relationship is lost, the wind resistant structure cannot be maintained. As shown in FIG. 3 (b) → (c), it is possible to repair by fixing the roof tiles individually and securely with the fixing screws 31 by processing the hidden fixing holes so that the fixing holes 23 appear. .
Thus, in the case where the engaging protrusion 25 is damaged and lost, it has been conventionally repaired with an adhesive or the like, but according to the present invention, an advantage that wind resistance performance can be maintained for a long time can be obtained. .

  The position where the fixing hole 23 (hidden fixing hole) is provided is a portion close to the head of the bank-shaped water return 22 arranged in the underlap 21, but the fixing screw 31 is in a raised state. It is set so as to be shifted from the tip of the head at a position where it does not interfere with the bottom of the roof tile arranged on the lower side. More specifically, it is preferably provided in the range of 50 mm to 150 mm in the butt direction from the underlap head end.

(Embodiment 3)
The present invention can be more preferably embodied even in the case of a disaster prevention tile as shown in FIG.
That is, the engagement protrusion 35 is formed on the top surface of the bottom of the clay roof tile 3 shown in FIG. This is a case of a disaster prevention clay roof tile provided with a wind-resistant structure in which a tip portion of the engaging projection 35 of the roof tile is inserted and the upper and lower roof tiles are engaged.

  In this disaster prevention roof tile, if for some reason it is damaged and lost in the engagement projection 35, the fixing hole 33 appears by processing the hidden fixing hole as in the case of the second embodiment. It is possible to repair the roof tiles individually with screws (not shown) to securely fix the roof tiles individually.

(Embodiment 4)
The present invention can be more preferably embodied even in the case of a disaster prevention tile as shown in FIG.
That is, the engagement protrusion 45 is formed on the upper surface of the bottom side of the clay roof tile 4 shown in FIG. 9, and the side end portion 46 of the head of the roof tile arranged on the upper side when the roof is raised is the above-mentioned roof tile. This is a case of a disaster prevention clay roof tile that is inserted below the front end portion of the engagement protrusion 45 and has a wind-resistant structure in which the upper and lower roof tiles are engaged.

  Also in this disaster prevention tile, if for some reason it is damaged and lost by the engagement protrusion 45, the fixing hole 43 appears by processing the hidden fixing hole as in the second and third embodiments. This makes it possible to repair the roof tiles individually and securely with the fixing screws (not shown).

  In the first and second embodiments of the disaster prevention tile according to the present invention, one concealed fixing hole is provided in which a fixing screw 31 can be screwed into a portion close to the head of the bank-like water return 22 arranged in the underlap 21. However, it may be arranged at a plurality of locations. That is, when it is used as an eaves tile, a preferable roof base material for fixing the fixing screw 31 is a wide and small dance, but when it is not an eaves tile, the fixing screw 31 is fixed to the tile pier. It is preferable in terms of strength. Therefore, it is preferable to arrange hidden fixing holes in at least two places with a space in the front and rear so as to match the positions of the wide and small tiles and the tile pier. Needless to say, these are the same as in the third and fourth embodiments.

  In addition, in the case of the use of the disaster prevention tile of the present invention other than the eaves tile, even if these hidden fixing holes are not used, the surface of the part is closed, so there is a risk of water leakage toward the base material. Nor. Furthermore, the disaster prevention tile of the present invention has an advantage that the roof tile can be firmly fixed to the base material using the hidden fixing holes even in the case of uses other than the eaves tile.
