Abstract

<P>PROBLEM TO BE SOLVED: To easily receive discharge rainwater discharged forward from the tip of an eaves end roof tile, by restraining water wetting of an eaves edge wood part, by preventing flowing-down rainwater from falling in the inside direction. <P>SOLUTION: This eaves end roof tile is constituted so as to shorten the height of a suspending part surface part 22a more than a surface part 24a of a virtual suspending part 24 formed on the tip of a head part by bending at a substantially right angle, by forming a part between a main plate surface 21 and a suspending part 22 into an inclined face 23, by arranging the suspending part 22 on the tip of the head part. Thus, since the height of the suspending part surface part 22a is shortened, the flowing-down rainwater is hardly guided inside, and since the discharge rainwater discharged from the tip of the eaves end roof tile approaches the flowing-down rainwater, a rain gutter can be easily installed. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to an improvement in the shape of eaves tiles arranged at the eaves of a roof.

  As shown in FIG. 7, the construction state of the eaves tile that has been conventionally performed is that the eaves tile 1 is placed on the roof base material, for example, the tile seat 12 provided on the base plate 11 and the tile rail 13 at the eaves edge. A rain gutter 14 for receiving rain water flowing down along the surface of the eave roof tile 1 is fixed to the nose cover 15.

  Here, the eaves tile 1 has a drooping portion 10 formed at a right angle to the surface at the tip thereof, and guides the rainwater flowing down to the rain gutter 14 when it rains. However, in the case of heavy rain or strong winds, the falling rainwater does not fall in the vertical direction toward the rain gutter 14, travels from the surface of the drooping portion 10 to the bottom surface, scatters in the inner direction, and closes the nose cover 15. In some cases, the function of draining water was not sufficient.

  In order to solve such a problem, a rainwater scattering prevention tool (not shown) attached to the tip of the drooping portion 10 has been proposed (see Patent Document 1). Since the rainwater scattering prevention tool is an extra member that is prepared separately from the eaves tile main body, there are problems that the material cost and the mounting processing cost are excessively increased and the aesthetic appearance is impaired.

Furthermore, what copes with the shape of the drooping part 10 is proposed as a thing corresponding to such a problem (refer patent document 2). In this proposal, as shown in FIG. 8, a surface 1 a of a hanging portion 10 is formed at a top end of the eave roof tile 1 in a direction substantially perpendicular to the upper surface of the eave roof tile 1. An outwardly bulging curved surface 1b is formed from the part to the back part. In the case of this eave roof tile 1, it is said that the falling rainwater has an outwardly bulging curved surface 1b, so that it falls in a substantially vertical direction without splashing inward.

  However, even in the case of Patent Document 2, the rainwater flowing down is guided to the surface 1a of the drooping portion 10 and falls inward, so that it cannot be completely prevented from scattering toward the eaves wood. . In addition, if the rain gutter 14 is arranged to be biased inward, it becomes easy to receive the falling rainwater falling toward the inside. However, when the degree of rainfall increases, the flowing rainwater will be discharged forward from the front edge of the eaves tile without passing through the drooping portion 10, but it is difficult for the rain gutter 14 biased inward to receive this rainwater. The problem of becoming.

  The present invention has been made to solve the above problems, and by devising the shape of the hanging portion of the eaves tile, making it difficult for falling rainwater to fall inwardly, wetting the eaves wood portion An eaves tile that can easily receive water from the rainwater discharged forward from the front end of the eaves tile.

In the eave roof tile provided with a hanging portion at the tip of the head, the above-mentioned problem is the first invention, and an inclined surface is formed between the main plate surface and the hanging portion, and the height of the surface portion of the hanging portion is reduced. This can be solved by the eaves tile according to the present invention.
In the present invention, it is preferable to provide a step portion at the tip of the inclined surface, and it is preferable that the inclined angle of the inclined surface is at least 35 ° with respect to the main plate surface. Furthermore, it is preferable that the inclined surface is formed in the vicinity of the valley of the head portion of the main plate surface.

  In addition, in the eaves tile provided with a hanging part at the tip of the head, the above problem is the second invention. When the roof tile is struck by the roof, the surface of the hanging part is vertical or the lower end of the hanging part is forward. It can be solved by the eaves tile according to the present invention characterized in that the surface of the hanging portion is inclined with respect to the main plate surface so as to protrude. And this invention is preferably embodied in the form which the surface lower end part of the said drooping part formed in 90 degrees or an acute angle.

  According to the first invention described above, in the eave roof tile provided with the hanging portion at the tip of the head, since the bent portion of the main plate surface and the hanging portion is formed on the inclined surface, compared with the case where this inclined surface is not formed. Since the height of the surface portion of the drooping portion is shortened, the degree to which the flowing rainwater is guided to the inside by the dripping portion is reduced, so that it is difficult to fall inside. Further, since the rainwater discharged forward from the front end of the eaves tile and the falling rainwater are close to each other, there is an advantage that installation of the rain gutter is easy.

  In the second aspect of the invention, the drooping portion itself is an inclined surface with the lower portion directed forward, so that falling rainwater is guided outward by the dripping portion, so that it is more difficult to fall inward. Moreover, since the rainwater discharged forward from the front edge of the eaves tile and the falling rainwater are closer to each other, the problem of facilitating installation of the rain gutter and difficulty in receiving water is solved. Thus, both the first and second inventions have the excellent effect of suppressing the water wetting of the eaves end wood part and easily receiving the rainwater discharged forward from the eaves tile tip. Therefore, the present invention has an extremely large practical value as an eave roof tile that has solved the conventional problems.

Next, an embodiment of the present invention will be described with reference to FIGS. 1 to 3 for the first invention and FIGS. 4 to 6 for the second invention.
(First invention)
In the first embodiment, the eave roof tile according to the present invention is the eave roof tile 2 provided with the drooping portion 22 at the tip of the head. However, the sloping surface 23 is formed between the main plate surface 21 and the drooping portion 22, and the drooping portion is formed. This is characterized in that the height of the surface portion 22a is shortened.

  Here, in FIG. 1, the well-known hanging portion of the eaves tile is a virtual hanging portion 24 indicated by a portion (a portion surrounded by a chain line) formed by bending substantially perpendicularly to the tip of the head. The main plate surface 21 and the virtual drooping surface 24a are continuous by a right angle portion. And in this invention, since it formed in the inclined surface 23 of inclination | tilt angle (theta) between the main plate surface 21 and the drooping part 22, the drooping part surface part 22a is the said virtual dripping part surface part in case the inclined surface 23 is not provided. Compared with 24a, the height can be greatly shortened.

According to the first embodiment, the height of the drooping portion surface portion 22a is shorter than that of the conventional drooping portion 24, which is preferable in that it is difficult for the flowing rainwater to be guided to the inside. Since the rainwater discharged from the tip and the falling rainwater are close to each other, there is an advantage that the installation of the rain gutter becomes easy.
Further, according to the present invention, when the step portion 25 is provided at the tip portion of the inclined surface 23 as in the second embodiment shown in FIGS. 2 and 3, the height of the drooping portion surface portion 22a is further shortened. The advantage is that the rainwater discharged from the front edge of the eaves tile is more relaxed.

The inclination angle θ of the inclined surface 23 is preferably set to at least 35 ° with respect to the main plate surface 21 from the viewpoint of effectively functioning the inclined surface 23. In addition, it is preferable that the bottom surface of the drooping portion is provided with an upward inclination angle θ1 with respect to the main plate surface 21 because the draining effect can be enhanced.
Furthermore, in the said description, although the said inclined surface 23 was illustrated by providing in the full width of the head of the main plate surface 21, this invention is not limited to this. For example, even if the inclined surface 23 is formed only in the vicinity of the center of the head, that is, in the vicinity of the valley, the above-described effect can be obtained in the same manner.

(Second invention)
In the second invention, as shown in FIG. 4, an eaves tile provided with a hanging part 32 bent downward at the head end of the main plate surface 31 of the eaves tile 3 is an object, and the hanging part surface 32 a When the eaves tile is laid on the roof, as shown in FIG. 5, the hanging portion surface 32a is placed on the main plate surface so that the hanging portion lower end portion 32b protrudes forward or the hanging portion surface 32a is vertical. It is characterized in that it is formed obliquely with respect to 31.

In order to obtain the drooping portion surface 32a under such conditions, when the rolling inclination angle of the eaves tile 3 is θ4, the inclination angle of the dripping portion surface 32a with respect to the main plate surface 31, that is, the drooping portion inclination angle θ3 ≦ 90 ° − It will be easily understood that θ4 may be satisfied.
In general, the roofing tile's angle of inclination θ4 is said to be a gentle gradient when the gradient is 3 or 5 minutes (19 ° 17 ') or less, a steep gradient or more than 5 or 5 minutes (28 ° 48'), and a normal gradient between them. ing. Then, with the 5-dimensional gradient (26 ° 34 ′), which is the upper limit of the most commonly used normal gradient, as a reference, the drooping portion inclination angle θ3 ≦ 90 ° −θ4≈90−26 = 64 ° is established. In addition, the eave roof of the present invention having a wide practical application range can be obtained.
In the present invention, it is preferable that the angle θ5 of the surface lower end portion 32b of the hanging portion is 90 ° or an acute angle because the draining effect is improved.

  Thus, according to this embodiment of the second invention, since the drooping portion itself is an inclined surface directed forward, the falling rainwater is guided outward by the drooping portion, and therefore, it is more difficult to fall inward. Moreover, since the rainwater discharged forward from the front edge of the eaves tile and the falling rainwater are closer to each other, the problem of facilitating installation of the rain gutter and difficulty in receiving water is solved. Thus, both the first and second inventions of the present invention exhibit the excellent effect of suppressing the water wetting of the eaves tip wood part and also being able to easily receive the rainwater discharged forward from the front end of the eaves tile. .
