Description

  The present invention relates to an eaves tile made of fired tiles or slate tiles, and more particularly to an eaves tile that can reliably prevent the intrusion of rainwater even in strong winds.

  Fired tiles and slate tiles are spread on the roof of the building. The roof base is obtained by fixing a field board such as plywood on a tree and fixing a waterproof sheet called roofing on the field board. In this roof structure, fired tiles and slate tiles are spread on a waterproof roof base to prevent leakage. However, even with this structure, it is extremely difficult to effectively prevent rain leakage during the strong winds at the eaves. This is because the strong wind blows rainwater between the eaves tile and the roof base. The roof base adjusted by the tarpaulin cannot be made completely waterproof, and a large amount of rainwater enters here, causing rain leakage.

A structure has been developed that prevents rainwater from entering between the eaves tile and the roof under the strong wind. (See Patent Documents 1 and 2)
JP-A-7-166654 JP 2005-213727 A

  As shown in the cross-sectional view of FIG. 1, the eaves roof tile of Patent Document 1 is provided with a front wall 22 that protrudes downward along the front edge of the main body 21. Further, the front wall 22 is provided with a bent piece portion 23 along the lower end edge, and the bent piece portion 23, the front wall 22 and the main body portion 21 are provided with a concave groove 24. The eaves tile having this structure can prevent rainwater from entering at the bent piece 23, and in particular, rainwater that is blown under the eaves tile by a strong wind blowing in the direction of the arrow. However, the eaves tile with this structure has a drawback that it takes much time to manufacture and the manufacturing cost is high. In particular, in eaves tiles such as fired roof tiles and slate roof tiles that are molded with clay or mortar using a mold, there is a bent piece that bends inward, so that it cannot be removed from a normal mold. For this reason, in order to shape | mold a bending piece part, it is necessary to use the metal mold of the complicated structure designed specially, and manufacturing cost becomes high.

  Patent Document 2 describes a flat roof tile instead of an eaves roof tile. As shown in the sectional view of FIG. 2, this flat roof tile is provided with a hanging portion 32 on the front lower surface of the main body 31. This flat roof tile can be molded with a mold as a fired roof tile or a slate roof tile. However, when a flat roof tile with this structure is used as an eaves tile, there is a drawback that the eaves portion 32 is conspicuous in the state of being laid on the roof and the eaves cannot be finished neatly.

  The present invention has been developed for the purpose of solving this drawback. An important object of the present invention is that it can be efficiently and inexpensively produced as a fired roof tile or a slate roof tile in a large amount at a low cost, and it can reliably prevent the intrusion of rainwater under the roof tile due to strong winds. The goal is to provide eaves tiles that can be finished to the exterior.

The eaves tile according to the present invention is an eaves tile made of fired tile or slate tile provided with a front wall 2 projecting downward along the front edge of the main body 1.
In the eaves tile according to claim 1 of the present invention, the front wall 2 has a predetermined thickness, and a longitudinal groove 3 extending in the longitudinal direction is provided on the lower surface.

The inclined surface 5 is inclined in the direction of thinning the front wall 2 from below to above, and a vertical surface 6 is provided on the upper edge of the inclined surface 5.

  The eaves tile according to claim 3 of the present invention is provided with a back groove 7 or a back ridge 8 that extends away from the front wall 2 and extends along the front wall 2 on the lower surface of the main body 1.

  In the eaves tile according to claim 4 of the present invention, the front wall 2 has a predetermined thickness, and a longitudinal groove 3 extending in the longitudinal direction is provided on the lower surface. Further, the eaves tile is provided with a step-like unevenness 4 consisting of repetition of an inclined surface 5 and a vertical surface 6 on the back surface of the front wall 2. The inclined surface 5 is inclined in the direction of thinning the front wall 2 from below to above, and a vertical surface 6 is provided on the upper edge of the inclined surface 5.

  The eaves tile according to claim 5 of the present invention is provided with a step-like unevenness 4 formed by repeating an inclined surface 5 and a vertical surface 6 on the back surface of the front wall 2. The inclined surface 5 is inclined in the direction of thinning the front wall 2 from below to above, and a vertical surface 6 is provided on the upper edge of the inclined surface 5. Further, the eaves tile is provided with a back groove 7 or a back ridge 8 on the lower surface of the main body 1 so as to be along the front wall 2 away from the front wall 2.

  In the eaves tile according to claim 6 of the present invention, the front wall 2 has a predetermined thickness, and a longitudinal groove 3 extending in the longitudinal direction is provided on the lower surface. Further, the eaves tile is provided with a back groove 7 or a back ridge 8 on the lower surface of the main body 1 so as to be along the front wall 2 away from the front wall 2.

  In the eaves tile according to claim 7 of the present invention, the front wall 2 has a predetermined thickness, and a longitudinal groove 3 extending in the longitudinal direction is provided on the lower surface. Further, the eaves tile is provided with a step-like unevenness 4 consisting of repetition of an inclined surface 5 and a vertical surface 6 on the back surface of the front wall 2. The inclined surface 5 is inclined in the direction of thinning the front wall 2 from below to above, and a vertical surface 6 is provided on the upper edge of the inclined surface 5. Furthermore, the eaves tile is provided with a back groove 7 or a back ridge 8 along the front wall 2 on the lower surface of the main body 1 away from the front wall 2.

  The eaves tile according to the present invention has a feature that can effectively prevent rainwater from entering under the eaves tile in a strong wind while having a structure that can be efficiently produced at low cost in a mold as a fired tile or a slate tile. In particular, since the eaves tile according to claim 1 has a vertical groove on the lower surface of the front wall that protrudes downward along the front edge of the main body, rainwater enters the eaves tile under the eaves tile. Can be effectively prevented. As shown by the arrows in FIG. 3, the eaves roof tiles are particularly likely to infiltrate downward when strong horizontal winds blow. Because the eaves tile is close to the bottom of the roof tile, a strong wind does not blow from the bottom to the top, but a strong wind may blow in the horizontal direction from between the roof tile and the fence. When heavy rain falls and strong winds blow in this direction, rainwater that flows down along the front of the front wall flows along the lower surface of the front wall and tries to enter under the eaves tile. The eaves tile according to claim 1 of the present invention has a vertical groove provided on the lower surface of the front wall, and drains and blocks rainwater flowing along the surface of the front wall. Can be effectively prevented. Furthermore, this eaves tile has the feature that the energy of the wind flowing on the lower surface of the front wall can be attenuated by the vertical groove.

  In addition, the eaves tile according to claim 2 of the present invention is provided with stepped irregularities formed by repeating an inclined surface and a vertical surface on the back surface of the front wall protruding downward along the front edge of the main body. The stepped irregularities can effectively prevent rainwater from entering under the eaves tile. As shown in FIG. 3, the strong wind blown horizontally on the eaves tile forms a vortex on the back surface of the front wall and winds rainwater along the back surface of the front wall. The eaves tile according to claim 2 of the present invention is provided with stepped irregularities formed by repeating an inclined surface and a vertical surface on the back surface of the front wall, and in particular, the inclined surface thins the front wall from the bottom to the top. The vertical surface is provided on the upper edge of the inclined surface. The stepped irregularities of this structure drain and block rainwater rising along the back surface of the front wall and prevent the swirled wind from raising rainwater along the back surface. Therefore, it is possible to effectively prevent rainwater that has flowed into the back surface of the front wall from entering the bottom of the eaves tile due to the strong wind. Further, the eaves tile has a feature that the energy of wind flowing upward along the back surface of the front wall can be attenuated by the stepped unevenness.

  Moreover, the eaves tile of Claim 3 of this invention is provided with the back groove | channel or back convex strip which is separated from the front wall and extended in the direction along a front wall in the lower surface of a main-body part. This eaves roof tile drains rainwater that tries to flow under the eaves tile along the lower surface of the main body section by draining it with a back groove or back ridge, so that rainwater enters under the eaves tile due to strong winds. Can be effectively prevented. In order for rainwater to enter between the eaves tile and the roof base, it must flow over the back groove or back ridge, but the back groove or back ridge drains the rainwater, so the rain It is because it can prevent exceeding a back ridge.

  Furthermore, the eaves tile according to claim 4 of the present invention is provided with vertical grooves on the lower surface of the front wall, and stepped irregularities formed by repeating an inclined surface and a vertical surface on the back surface of the front wall. As a result of this synergistic action, rainwater can be more effectively prevented from entering under the eaves tile.

  Furthermore, the eaves tile according to claim 5 of the present invention is provided with stepped irregularities formed by repeating an inclined surface and a vertical surface on the back surface of the front wall, and on the front wall away from the front wall on the lower surface of the main body. Since the back groove | channel or back ridge which follows is provided, it can prevent more effectively that rainwater penetrate | invades under an eaves tile by these synergistic actions.

  Furthermore, the eaves tile according to claim 6 of the present invention is provided with a vertical groove on the lower surface of the front wall, and on the lower surface of the main body portion is provided with a back groove or a back ridge along the front wall away from the front wall. These synergistic actions can more effectively prevent rainwater from entering under the eaves tile.

  Furthermore, the eaves tile according to claim 7 of the present invention is provided with a vertical groove on the lower surface of the front wall, a stepped unevenness on the back surface of the front wall, and a back groove or a back ridge on the lower surface of the main body. , Can most effectively prevent the intrusion of rainwater. This eaves tile can reliably prevent the intrusion of rainwater even in bad weather such as a typhoon where a lot of rain falls and a very strong wind blows.

  Further, the eaves tile according to the present invention is a vertical groove provided on the lower surface of the front wall, a step-like unevenness provided on the back surface of the front wall, or a back groove or a back ridge provided on the lower surface of the main body portion. Prevent rainwater from entering underneath. That is, the lower surface and the back surface of the front wall or the lower surface of the main body is made into a unique structure to prevent rainwater from entering. Therefore, there is a feature that can reliably prevent the intrusion of rainwater while making the front and top surfaces of the eaves tile beautiful.

  Furthermore, the eaves roof tile of the present invention is specially designed because it can be removed using a normal mold, despite having a unique structure with the lower and back surfaces of the front wall or the lower surface of the main body. There is a feature that mass production can be performed at low cost while reducing the manufacturing cost without using a mold having a complicated structure.

  Embodiments of the present invention will be described below with reference to the drawings. However, the example shown below illustrates the eaves roof tile for embodying the technical idea of the present invention, and the present invention does not specify the eave roof tile as described below.

  Further, in this specification, in order to facilitate understanding of the scope of claims, numbers corresponding to the members shown in the examples are indicated in the “claims” and “means for solving problems” sections. It is added to the members. However, the members shown in the claims are not limited to the members in the embodiments.

  The eaves tile shown in FIGS. 3 to 5 is provided with a front wall 2 that protrudes downward along the front edge of the main body 1. The eaves tile is a fired roof tile formed from clay and fired, or a slate roof tile molded from mortar and cured. The eaves tile shown in the figure has a front wall 2 of a predetermined thickness and a longitudinal groove 3 extending in the longitudinal direction on the lower surface.

  The front wall 2 is substantially perpendicular to the main body 1, but is accurately connected to the main body 1 so as to be slightly obtuse. As shown in FIG. 4, the front wall 2 has an obtuse angle (α) formed between the back surface and the lower surface of the main body 1, and an obtuse angle (β) formed between the front surface and the upper surface of the main body 1. . The eaves tile is slightly thinner than the main body 1 in the thickness of the front wall 2. For example, the thickness of the main body 1 is 18 mm and the thickness of the lower end of the front wall 2 is 15 mm. However, the eaves tile can have a main body thickness of 15 mm to 20 mm and a front wall thickness of 10 mm to 17 mm.

  The front wall 2 in the figure is provided with a vertical groove 3 along the center of the lower surface. The longitudinal groove 3 has a depth of about 1.5 mm and a width of about 5 mm. The vertical groove 3 in the figure has an opening width wider than the bottom width. The eaves roof tile having the vertical groove 3 in this shape can be molded and fired neatly, and the cement can be hardened. However, the depth of the longitudinal groove can be, for example, 1 mm to 5 mm, preferably 1 mm to 3 mm, and more preferably 1 mm to 2 mm. The width of the longitudinal groove can be 1 mm to 10 mm, preferably 2 mm to 8 mm.

  The vertical groove 3 drains rainwater flowing down along the front surface of the front wall 2 at the lower surface of the front wall 2. Rainwater flowing on the upper surface of the main body portion 1 of the eaves tile flows down along the front surface of the front wall 2. As shown by the arrows in FIG. 3, this rainwater flows along the lower surface of the front wall 2 by the wind blown from the front and tries to enter under the eaves tile. At the eaves of the roof, the ridge 11 is provided close to the lower end of the roof base 10, so that strong wind does not blow from the bottom to the top, but there is strong wind in the horizontal direction between the eaves tile and the ridge 11. May be infused. The vertical groove 3 drains rainwater flowing on the lower surface of the front wall 2 and prevents it from entering under the eaves tile. The vertical groove 3 drains rainwater flowing along the lower surface of the front wall 2 and attenuates the energy of wind flowing through the lower surface of the front wall 2. As shown in FIG. 3, the wind flowing on the lower surface of the front wall 2 becomes a vortex on the back surface of the front wall 2 and winds rainwater along the back surface of the front wall 2.

  The eaves tiles in FIGS. 3 to 5 are provided with stepped irregularities 4 on the back surface of the front wall 2 in order to prevent wind from becoming swirl and causing rainwater to rise along the back surface of the front wall 2. ing. The step-like unevenness 4 is formed by repeating an inclined surface 5 and a vertical surface 6, and the inclined surface 5 is inclined in the direction of thinning the front wall 2 from the bottom to the top, and is perpendicular to the upper edge of the inclined surface 5. Surface 6 is provided. The eaves tile shown in the figure is provided with two steps of stepped irregularities 4. The inclined surface 5 has a vertical width of 3 to 20 mm, preferably 5 to 10 mm, and the vertical surface 6 has a width of 1 to 3 mm, preferably 1 to 1.5 mm. The width of the vertical surface 6 specifies the inclination angle of the inclined surface 5. By increasing the width of the vertical surface 6, the inclination angle of the inclined surface 5 can be increased. On the other hand, the angle of the inclined surface 5 can be reduced by reducing the width of the vertical surface 6. By increasing the width of the vertical surface 6, it is possible to more reliably prevent rainwater from rising along the back surface of the front wall 2. However, when the width of the vertical surface 6 is increased and the inclination angle of the inclined surface 5 is increased, it is difficult to remove the mold for forming the back surface of the eaves tile. In order to simplify the demolding of the mold, molding is performed so that the angle (α) formed by the inclined surface 5 and the lower surface of the main body 1 is 90 degrees or more, preferably 90 degrees or more and 95 degrees or less.

  The stepped irregularities 4 composed of the inclined surface 5 and the vertical surface 6 prevent rainwater from rising along the back surface of the front wall 2 and also attenuate the energy of wind flowing upward along the back surface. The wind that flows along the rear surface of the front wall 2 flows from the front wall 2 toward the lower surface of the main body 1, and causes rainwater flowing on the rear surface of the front wall 2 to enter the lower surface of the main body 1. The step-like unevenness 4 drains rainwater on the back surface of the front wall 2 and attenuates wind energy to prevent the wind from entering the lower surface of the main body 1.

  As described above, the eaves roof tile provided with the vertical groove 3 on the lower surface of the front wall 2 and the step-like unevenness 4 on the back surface has a synergistic effect between the vertical groove 3 and the step-like unevenness 4 so that It is possible to effectively prevent rainwater from entering. However, when a lot of rain falls like a typhoon, and a very strong wind blows horizontally toward the eaves tile, the rainwater passes over the vertical grooves 3 and the stepped irregularities 4 of the front wall 2, and the main body 1 May penetrate into the underside of the. The eaves tile shown in the figure has a back groove 7 on the lower surface of the main body 1 in addition to the vertical groove 3 and the stepped irregularities 4 in order to reliably prevent intrusion of rainwater even in extremely severe environments such as typhoons. Yes. The back groove 7 is provided so as to be separated from the front wall 2 and extend in a direction along the front wall 2. The eaves tile in the figure is provided with two rows of back grooves 7 apart.

  The back groove 7 has a depth of about 1.5 mm and a width of about 5 mm. The back groove 7 in the figure has an opening width wider than the bottom width. The eaves tile having the back groove 7 in this shape can be molded and fired cleanly, and the cement can be hardened. However, the depth of the back groove can be, for example, 1 mm to 5 mm, preferably 1 mm to 3 mm, and more preferably 1 mm to 2 mm. The width of the back groove may be 1 mm to 10 mm, preferably 2 mm to 8 mm.

  The back groove 7 is provided at a position protruding from the front end of the roof base 10 in a state in which the eaves tile is spread on the roof. As shown in FIG. 3, the eaves tile is fixed at a position protruding from the leading edge of the roof base 10. The protruding dimension of the eaves tile from the roof base 10 is 2 to 2.5 (about 6 to 7.5 cm). The eaves tile has a space of 2 to 2.5 inches between the front surface of the front wall 2 and the tip of the roof base 10, and a gap 12 is formed between the front wall 2 and the roof base tip edge. Fixed to. The back groove 7 is provided on the lower surface of the main body 1 so as to be positioned in the gap 12 between the front wall 2 and the roof base 10. The eaves roof tile provided with two rows of back grooves 7 has a distance between the center line of the back groove 7 near the front wall 2 and the front surface of the front wall 2 of about 5.5 cm, and is separated from the front wall 2. The distance between the center line of 7 and the front surface of the front wall 2 is about 7 cm. As shown by the chain line in FIG. 4, when the eaves tile is in a state of being projected 2 inches (about 6 cm) from the roof base 10, one row of back grooves 7 is disposed in the gap 12. In addition, as shown by the solid line in FIG. 4, two rows of back grooves 7 are disposed in the gaps 12 in a state where the roof base 10 protrudes 2.5 inches (about 7.5 cm).

  Furthermore, as shown in FIG. 6, the eaves tile can be provided with a back ridge 8 on the lower surface of the main body 1. The back ridge 8 is a ridge that protrudes downward from the lower surface of the main body 1 and is separated from the front wall 2 and extends in a direction along the front wall 2 in the same manner as the above-described back groove. Provided. The back protrusion 8 has a protruding height from the lower surface of the main body 1 of about 1.5 mm and a width of about 5 mm. The back ridge 8 in the figure has the width of the front end surface narrower than the width of the rear end. An eaves roof tile having the back ridge 8 in this shape can be molded and fired neatly, and the cement can be hardened. However, the protruding height of the back ridge can be set to, for example, 1 mm to 5 mm, preferably 1 mm to 3 mm. Further, the width of the back ridge may be 1 mm to 10 mm, preferably 2 mm to 8 mm.

  In addition, the eaves tile of FIG. 6 is provided with two rows of back ridges 8 separated from each other. The two rows of back ridges 8 are provided at the same position as the above-described back groove, that is, at a position protruding from the front end of the roof base 10 in a state in which the eaves tile is run over the roof. The back ridge 8 is provided on the lower surface of the main body 1 so as to be positioned in the gap 12 between the front wall 2 and the roof base 10. The eaves tile provided with two rows of back ridges 8 is separated from the front wall 2 by setting the distance between the center line of the back ridges 8 close to the front wall 2 and the front surface of the front wall 2 to about 5.5 cm. The distance between the center line of the back ridge 8 and the front surface of the front wall 2 is about 7 cm. As shown by the chain line in FIG. 6, when the eaves tile is in a state of being projected 2 inches (about 6 cm) from the roof base 10, one row of back ridges 8 is disposed in the gap 12. Further, as shown by the solid line in FIG. 6, in a state where the roof base 10 protrudes by 2.5 inches (about 7.5 cm), two rows of back ridges 8 are disposed in the gap 12. .

  The above eaves tiles are provided with two rows of back grooves 7 or back ridges 8 on the lower surface of the main body 1, but the eaves tiles are provided with one or more rows of back grooves on the lower surface of the main body 1. Alternatively, a back ridge can be provided. Further, although not shown, the eaves tile can be provided with both a back groove and a back ridge on the lower surface of the main body. For example, the eaves tile can be provided with a row of back grooves and a row of back ridges parallel to each other on the lower surface of the main body. This eaves roof tile can effectively prevent the intrusion of rainwater by both the back groove and the back ridge having different shapes.

  The back grooves 7 and the back ridges 8 disposed in the gap 12 between the front wall 2 and the roof base 10 effectively prevent rainwater that enters between the roof base 10 along the lower surface of the main body 1 due to strong wind. Drain the water. In particular, the eaves tile shown in the figure drains rainwater and attenuates wind energy by means of the longitudinal grooves 3 and the stepped irregularities 4 of the front wall 2. For this reason, since the amount of rain water crossing the back groove 7 or the back ridge 8 is small, and the energy of the wind blown along the lower surface of the main body 1 is also small, the back groove 7 or the back ridge 8 is used. Infiltration of rainwater can be reliably prevented. In order for rainwater to enter between the eaves tile and the roof base 10, it is necessary to flow beyond the back groove 7 or the back ridge 8, but the back groove 7 or the back ridge 8 drains the rainwater, Since the wind energy is also attenuated, the rainwater does not exceed the back grooves 7 or the back ridges 8, and rainwater that enters between the eaves tile and the roof base 10 can be reliably prevented. In particular, the eaves tile in the figure is drained by the vertical grooves 3 and the stepped irregularities 4 of the front wall 2, attenuates wind energy, and drains rainwater by the back grooves 7 or the back ridges 8 to wind. Therefore, even if the amount of rain is extremely large, such as a typhoon, and the wind blowing rainwater between the roof base 10 is extremely strong, the intrusion of rainwater can be reliably prevented.
