Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an eaves accessory, and more particularly to an eaves accessory that is disposed at the edge of the eaves of a roof board and drains water from the roof.

Generally, this type of eaves accessory is formed by bending a metal plate into a substantially L-shape as shown in FIG. 1, so it is easily corroded and does not have a solid feel. In addition, since the thickness is small just by bending the metal plate, the eaves tile 10 is placed on the eaves accessory A, and the flat plate tile 11 is further placed on the eaves tile 10 to create a flat plate tile roof. In this case, 10 eaves tiles and 1 flat tile
1 and a gap 15 is created between the two, and rain and wind tend to enter this gap 15, which may cause the roof board 1 to get wet. Furthermore,
Since the eaves accessory A and the eaves tile 10 are in close contact with each other, rainwater that travels onto the eaves accessory A through the joints of the eaves tiles 10 permeates around the eaves accessory A due to capillary action. As a result, the roofing board 1 may get wet.

As a solution to these problems, the
- There is an eaves tile with draining as disclosed in Publication No. 120815, and in this eaves tile with draining, a horizontal groove and a plurality of grooves communicating with the horizontal groove are provided on the surface of the part laid under the flat tile. vertical grooves are formed. However, in this configuration, since there is no means for guiding water flow from the horizontal grooves to the vertical grooves, rainwater flowing in the horizontal grooves cannot be quickly guided to the vertical grooves. Also, if there is a slight inclination in the horizontal direction (direction perpendicular to the roof slope) when installing eaves tiles,
A problem arises in that rainwater concentrates in the vertical ditches on the downstream side, making them more likely to overflow.

The present invention has been made in view of the above-mentioned points, and its main purpose is to quickly drain rainwater without allowing it to seep onto the roof board, and to drain the rainwater perpendicularly to the roof slope. The purpose is to prevent rainwater from concentrating in one place and overflowing even if there is an inclination in the direction, and the other purpose is to create eaves accessories that will not corrode and have a solid feel. Another object of the present invention is to bring the eaves tile and flat tile into close contact with each other to prevent rain and wind from entering between them.

Embodiments of the present invention will be described below based on the drawings. As shown in FIGS. 2 to 4, the eaves accessory according to the present invention includes a horizontal piece 2 placed on the upper surface of the edge of the eaves of the roof board 1, and an approximately right angle from the front edge of the horizontal piece 2. In an eaves accessory in which a vertical piece 3 that is bent and protrudes downward is integrally formed of an inorganic material such as cement mortar, there is a continuous piece with an upper opening on both sides and the rear edge of the upper surface of the horizontal piece 2. A drainage ditch 4 is formed,
The entire drain groove 4 on both side edges opens on the front surface of the vertical piece 3, and at a fixed position in the left-right direction on the upper surface of the horizontal piece 2, the front end and the rear end run in the front-rear direction, and the front end opens on the front face of the vertical piece 3. A drainage auxiliary groove 7 whose rear end is open at the top and communicates with the drainage groove 4 at the rear edge is formed, and a flow path is connected to the drainage groove 4 at the intersection of the drainage groove 4 at the rear edge of the horizontal piece 2 and the drainage auxiliary groove 7. A protrusion 12 is provided to protrude forward from the rear end edge of the horizontal piece 2 and to be bent toward the drainage auxiliary groove 7. The vertical piece 3 is bent at a substantially right angle from the front edge of the horizontal piece 2 and projects downward. Horizontal piece 2
and the vertical pieces 3 are integrally formed of cement mortar reinforced with synthetic fibers. Horizontal piece 2 and vertical piece 3
The surface is matte painted. A drain groove 4 with a depth of 1 to 3 mm and a width of 3 to 15 mm opened on the top surface of the horizontal piece 2
is formed. As shown in FIG. 2, the drain groove 4 is formed along both side edges and the rear edge of the upper surface of the horizontal piece 2. The rear ends of the drain grooves 4 on both side edges are continuous with both left and right ends of the drain groove 4 on the rear edge, respectively. The front ends of the drain grooves 4 on both side edges are open to the front surface of the vertical piece 3. In addition, an auxiliary drainage groove 7 that runs forward communicates with the drainage groove 4 on the rear edge, and an auxiliary drainage groove 7 runs from the rear edge of the horizontal piece 2 at a portion where the drainage groove 4 and some of the auxiliary drainage grooves 7 intersect. A protrusion 12 narrower in width than the drainage auxiliary groove 7 is formed within the drain auxiliary groove 7 . Also,
A substantially U-shaped bent portion is formed in the drainage groove 4 at the rear edge, and the drainage auxiliary groove 7 is also in communication with this bent portion. A nail hole 6 penetrating the front and back sides of the horizontal piece is provided in a portion surrounded by the bent portion of the drain groove 4.
With this configuration, rainwater flowing through the drainage groove 4 on the rear edge of the horizontal piece 2 is directed into the drainage auxiliary groove 7 when it hits the protrusion 12 . As a result, the rainwater flowing through the drainage ditch 4 can be quickly introduced into the drainage auxiliary ditch 7, and the drainage speed can be increased. Further, even if the eaves accessory is inclined in a direction perpendicular to the roof slope, rainwater will not be concentrated in one of the drainage grooves 4 or the drainage auxiliary grooves 7 in the front-rear direction. The drainage auxiliary groove 7 has substantially the same depth and width as the drainage groove 4, and is open at the top, with the front end of the drainage auxiliary groove 7 opening at the front surface of the vertical piece 3. In addition, some drainage auxiliary grooves 7 have a part that runs diagonally forward or in the left-right direction in the middle between the front and back, which communicates with other drainage auxiliary grooves 7 and the drainage grooves 4 on both left and right edges. . On the other hand, on the front surface of the vertical piece 3, as shown in FIG.
is formed. This groove 8 makes it possible to give the front surface of the vertical piece 3 an appearance as if flat tiles were stacked in layers. In addition, a vertical groove 9 is formed on the front surface of the vertical piece 3, and when the eaves accessories are lined up left and right along the edge of the eaves of the field board 1, the alignment between adjacent eaves accessories is avoided. The joints are kept inconspicuous. The eaves accessory A formed as described above is as shown in FIGS. 3 and 4.
Horizontal pieces 2 are placed on the edges of the eaves of the sheathing board 1 and are successively lined up left and right, and fixed to the shedding board 1 with nails 5 through nail holes 6. An eaves tile 10 having a thickness substantially equal to the interval between the grooves 8 on the front surface of the vertical piece 3 described above is stacked on the horizontal piece 2 of the eaves accessory A. Eaves tiles 10
The rear end is placed on the field board 1, and nails 5 are attached to the field board 1.
is fixed. The eaves accessories A and the eaves tiles 10 have the same width in the left and right, and the joints between the eaves accessories A and the eaves tiles 10 are set at shifted positions in the left-right direction. Here, there is also a protrusion 1 inside the front end of the drainage auxiliary groove 7.
2, this protrusion 12 serves as a mark for positioning in the left-right direction, making positioning easier. Furthermore, the eaves accessory A
A protrusion 13 and a notch 14 are provided at the front end of both left and right edges of the
are provided, and the protrusion 13 and the notch 14 engage when connecting with the adjacent eaves accessory A, so that the front and back and top and bottom positioning can be performed. In this way, by not overlapping the joints of the two above and below, rainwater passing through the joints of the eaves tile 10 flows over the horizontal piece 2 of the eaves accessory A and does not flow onto the roof board 1. . At this time, since a drainage groove 4 and a drainage auxiliary groove 7 are provided on the upper surface of the horizontal piece 2, in the unlikely event that rainwater flows to the rear of the horizontal piece 2 or Even if the water flows to the left and right of the roof 2, it is received by both the grooves 4 and 7 and is reliably discharged, and as a result, the roofing board 1 is not wetted. Further, since the drainage groove 4 is bent around the nail hole 6 so as to surround the nail hole 6, rainwater can be reliably prevented from flowing through the nail hole 6. On the eaves tile 10 is a flat tile 1 having approximately the same thickness as the eaves tile 10.
1 are stacked, and on top of that, flat tiles 1 are placed one after another.
1 is covered. At this time, the eaves tile 10 and the flat tile 11
and are arranged in close contact with each other in substantially parallel manner due to the appropriate thickness of the horizontal piece 2 of the eaves accessory A. The flat tiles 11 at the edge of the eaves are arranged so that their joints are shifted from the joints of the eaves tiles 10 to the left and right. The front ends of the eaves tile 10 and the flat tile 11 are aligned vertically with the front surface of the vertical piece 3 of the eaves accessory A, so that the groove 8 on the front surface of the vertical piece 3, the eaves tile 10 and the flat tile 1
1, it is possible to give the appearance of a shape in which flat tiles 11 are stacked on the eaves.

What is shown in FIG. 6 is a drainage auxiliary groove 7 which extends forward from the left and right center of the drainage groove 4 at the rear edge in the front-rear direction and opens at the top, and the front end of the drainage auxiliary groove 7. is opened at the front of the vertical piece 3. A protrusion 12 is provided protruding from the front end and the rear end of the drainage auxiliary groove 7, respectively. Here, the protrusion 12 in the rear end of the drainage auxiliary groove 7 has the function of collecting rainwater flowing in the drainage groove 4 along the rear edge of the horizontal piece 2 into the drainage auxiliary groove 7, as in the embodiment shown in FIG. ing. The protrusion 12 is formed approximately in the center of the drainage auxiliary groove 7 on the left and right sides, and the upper end of the protrusion 12 is at the same height as the upper surface of the horizontal piece 2 or is slightly lower. This protrusion 12 is attached to the eaves tile 1 on the horizontal piece 2.
This is a guide for determining the left and right position of the eaves tile 10 when installing the eaves tile 1.
If the side edges of 0 are made to match, the eaves accessory A and the eaves tile 10 have the same left and right widths, so the joints between them will not match.

What is shown in FIGS. 7 and 8 is another embodiment, and shows various shapes of the drainage auxiliary groove 7.
Here too, the protrusion 12 naturally functions to introduce rainwater into the drainage auxiliary groove 7.

As mentioned above, the present invention is integrally formed from an inorganic material such as cement mortar.
It has the advantage that it does not corrode and can give a solid feeling, and by adding a desired thickness to the horizontal pieces, eave tiles and flat tiles can be placed in close contact almost parallel to each other. It has never happened before that the roof tiles get wet due to rain and wind getting in between them. In addition, continuous drainage grooves are formed on both sides and the rear edge of the upper surface of the horizontal piece, and the drainage grooves on both sides open on the front side of the vertical piece, so rainwater that has traveled on the eaves can be drained to the sides and rear. It has the advantage that it can be reliably discharged to the front without leaking, and as a result, it does not leak through the roofing board. In particular, at the intersection of the drainage groove and the drainage auxiliary groove on the rear edge of the horizontal piece, a protrusion that bends the flow path from the drainage groove to the drainage auxiliary groove is provided to protrude forward from the rear edge of the horizontal piece. By doing so, the rainwater flowing through the drain on the trailing edge of the horizontal piece can be diverted by the protrusion and collected towards the tip of the protrusion, and as a result,
This has the advantage that rainwater can be efficiently introduced into the drainage auxiliary groove, and the drainage speed of rainwater can be increased. In addition, even if the roof is installed at an angle perpendicular to the roof slope, rainwater flowing through the drainage ditch formed along the rear edge of the horizontal piece will flow forward and backward into the drainage ditch or drainage auxiliary ditch. This has the advantage that rainwater is not concentrated in one place, and rainwater can be prevented from overflowing.
