Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an eaves draining structure, and more particularly to an eaves draining structure capable of improving workability while ensuring waterproofness.

[0002]

2. Description of the Related Art A roof tile of a roof of a building such as a house has a relatively thin flat plate tile having a thickness of about 5 to 10 mm, or has a thickness exceeding the flat plate tile and has a heavy weight. Until now, various things such as tiles and corrugated tiles have been provided. Above all, the flat roof tile is thin as described above,
Therefore, since it is lightweight and excellent in workability, it has been widely used. On the other hand, the flat roof tiles have a drawback in that, due to their thin thickness, not only the appearance of three-dimensional feeling and heavy feeling is restricted, but also rainwater is more likely to infiltrate than other roof tiles. .

For this reason, in such a flat roof tile, as a measure against the intrusion of rainwater, generally, about half of the vertical width is used as an exposed portion, and the remaining substantially half portion is used as a non-exposed portion, and the flat roof tile is used as a roof surface. At the time of roofing, the eaves of the roof surface are first provided with eaves drainers such as steel plate-shaped tiles that are formed longer than the width of the flat tiles, and the roof tiles are taken with a large roofing allowance. It was the one that was being constructed in the direction of the building.

[0004]

However, even in the construction of such flat tiles, it is inevitable that rainwater will infiltrate from the joints between two flat tiles adjacent in the width direction, and the infiltration of rainwater is inevitable. It was not enough as a countermeasure.

Therefore, a connecting member having a draining function that allows water to infiltrate from the lower end portion or side end portion of the flat tile to flow toward the eaves side of the roof and drain it is provided. It has been considered to be arranged on the back surface between two flat tiles adjacent to each other in the width direction.

However, in order to specifically implement such disposition of the connecting member, it was necessary to solve the following problems. That is, it has been necessary to position the connecting member on the flat tile without forgetting to attach it, and to be able to attach the connecting member at an accurate position. For that reason, a construction method has been considered in which, using a convex or the like at the construction site, the position of each piece is measured and aligned, and the connecting member is fixed, but such a construction method is very troublesome and still poses a problem. Was what was left.

The present invention has been made in order to solve the above-mentioned problems, and an object thereof is to provide an eaves-draining structure capable of improving workability while ensuring waterproofness. To do.

FIG. 1A is a plan view showing an eaves-draining structure according to an embodiment of the present invention, and FIG.
[Fig. 2] is a sectional view of the eaves-draining structure of Fig. 1 (a).
FIG. 2A is an exploded view of only a main part of the eaves-draining structure according to the embodiment of the present invention, and FIG.
[Fig. 3] is a plan view of only a main part of the eaves edge draining structure of Fig. 2 (a). FIG. 3 is a schematic view showing an eaves edge drainer used in an eaves edge drainer structure according to another embodiment of the present invention. FIG. 4 is a plan view showing an outline of how flat roof tiles are constructed in the eaves draining structure of the present invention. FIG. 5 is a plan view of a main part showing an embodiment of tile roofing by constructing flat roof tiles in the eaves draining structure of the present invention.

As shown in FIGS. 1 to 5, the eaves draining structure of the present invention is a flat roof tile (1) in which only the ridge-side end portion is the unexposed portion (1a) and the remaining portion is the exposed portion (1b). Therefore, when the flat roof tile (1) is roofed on the roof surface, the eaves drainer (8) provided at the eaves roof portion (10) of the roof surface is formed to be longer than the horizontal width of the flat roof tile (1). In addition, in the eaves draining structure in which the ends of the eaves draining (8) are overlapped with each other, the flat roof tile (1) is used.
A connecting member (2) having a length equal to or substantially the same as the vertical width of the flat plate roof tiles (1) adjacent to each other in the horizontal width direction is arranged on the back surface of the abutting portion of the adjacent flat tiles (1). The eaves end of the same eaves at a constant span, including the seam part where the end portions of the eaves drainer (8) are overlapped with the alignment mark (9) indicating the attachment position of the connecting material (2). It is provided on the drainer (8).

First, regarding the construction of the flat roof tile, for example, as shown in FIG. 4, the flat roof tile (1) has only the non-exposed portion (1a) on the ridge side end, and the remaining portion is exposed. It is defined as a part (1b). The non-exposed part (1a)
As described above, the flat roof tile (1) placed directly above the roof tiles is a portion that is not exposed to the outside, and the exposed portion (1b) is a flat roof tile immediately below the roof tiles (1b). It is a portion that is superposed on the non-exposed portion (1a) of 1) and is exposed to the outside. Generally, the vertical width dimension of the flat roof tile (1) is about 400 to 500 mm, and only the ridge-side end of the flat roof tile (1) is a non-exposed portion (1a) of the non-exposed portion (1a). The vertical width can be roughly estimated to be about 1/5 to 1/4 of the vertical width of the whole flat roof tile (1).

When roofing a flat roof tile (1) having only the non-exposed portion (1a) as the ridge-side end and the exposed portion (1b) as the remaining portion, the flat roof tile (1) is struck in the width direction. On the back side of the abutting part of two flat roof tiles (1)
A draining and connecting member (2) having a length equal to or substantially equal to the vertical width of the flat roof tile (1) is provided. As described above, this connecting member (2) is a member that also serves as a drainer, that is, the thickness of the flat roof tile (1) is thinner than other roof tiles, and the roofing allowance is shorter than that of the conventional one. As a result, water that easily enters from the lower end and side edges of the flat roof tile (1) is blocked, and even if the flat roof tile (1) intrudes, the rainwater that has infiltrated is directed toward the eaves side of the roof (1). It is a member having a draining function that can be drained by flowing it on the surface of. Further, as the name implies, the connecting member (2) is also a member that connects two flat plate roof tiles (1) that are abutted in the lateral width direction and are adjacent to each other at their abutting portions.

As described above, the connecting member (2) has a length equal to or substantially equal to the vertical width dimension of the flat roof tile (1). This is because the connecting material (2) is not exposed and the appearance is not deteriorated. That the lengths are substantially equal includes, as shown in FIG. 4, those which are slightly shorter than the vertical width dimension of the flat roof tile (1), and those which are not shown but are slightly longer. . Connecting material (2), even if slightly longer
Is located below the flat roof tile (1) arranged by roofing and is not exposed. However, in order to minimize the workability of the connecting material (2) and the exposure to the outside, as shown in FIG. 4, the length of the connecting material (2) is larger than the vertical width dimension of the flat roof tile (1). It is effective to make it a little shorter.

The connecting member (2) is a flat roof tile (1).
In addition to being able to be produced to a predetermined length according to the vertical width dimension, it may be produced to some extent in a long length and appropriately cut at the construction site. This connecting member (2) is abutted in the lateral width direction and is disposed on the back surface of the abutting portion of two adjacent flat roof tiles (1),
It suffices if it is equal to or substantially equal to the vertical width dimension of the flat roof tile (1).

Then, in order to position and attach the connecting material (2) to the flat roof tile (1) at an accurate position and to perform the positioning easily and surely, the eaves tip (10) of the roof surface is provided. ) Is provided in addition to the eaves drainer (8), as shown in FIG. 4 and FIG.
In the central portion of the surface portion of the exposed portion (1b) of the flat roof tile (1), in the vicinity of the boundary with the non-exposed portion (1a), and in the central portion of the connecting material (2), for alignment, respectively. The roof tile mark (3) and the connecting material mark (4) are provided respectively.

The roof tile (3) provided on the flat roof tile (1) can be, for example, a protrusion or a groove, and can be formed simultaneously with the molding of the flat roof tile (1). The roof tile mark (3) can also be formed in various shapes, and as long as it is easily visible,
There is no particular limitation. For example, an inverted T-shape as shown in FIG. 4, an inverted V-shape, an inverted Y-shape, and an arrow shape can be used.

On the other hand, the connecting material mark (4) provided on the connecting material (2) is a ridge (4a) as shown in FIG.
That is, if the connecting member (2) is located in the central portion of the connecting member (2) in the longitudinal direction and protrudes upward, its formation is facilitated. Generally, the connecting material (2) can be made of metal and can be manufactured by sheet metal working. Therefore, the use of the ridges (4a) facilitates formation of the connecting material mark (4) on the connecting material (2).
However, in the case of using the ridges (4a), as described above, the connecting material (2) needs to be protected from being exposed so as not to affect the appearance of the building. It is preferable that the height of (4a) is such that it slightly protrudes upward and is within the thickness of the flat roof tile (1), as shown separately and enlarged in FIG.
On the other hand, the ridges (4a) may be provided over the entire length of the connecting material (2) or may be provided partially (for example, at predetermined intervals).

Needless to say, the material and manufacturing method of the connecting material (2) and the shape and size of the connecting material mark (4) are not limited to those in the above-mentioned embodiment. That is.

As described above, in the surface portion of the exposed portion (1b) of the flat roof tile (1), it is the central portion and the non-exposed portion (1b).
Since the roof tile mark (3) for alignment and the joint material mark (4) are provided in the vicinity of the boundary with a) and in the central portion of the joint material (2) respectively, both of them are required for roofing when roofing. By matching the roof tile mark (3) and the connecting material mark (4), the position of the connecting material (2) is uniquely determined,
The position of the connecting material (2) with respect to the flat roof tile (1) is accurately positioned, and it can be attached. Moreover, the positioning of the connecting member (2) with respect to the flat roof tile (1) is facilitated and can be reliably performed. And
After positioning, the connecting member (2) is mounted on the eaves side end on the non-exposed part (1a) at the ridge-side end of the flat roof tile (1), and the fixture (5) such as nails. ) Is arranged at right angles or substantially right angles to the flat roof tile (1) and can be fixed to the roof together with the flat roof tile (1).

Therefore, while the non-exposed portion (1a) of the flat roof tile (1) is reduced, the waterproofness is ensured and the roofing workability is improved. The roof tile is formed by placing the flat roof tile (1) on the connecting material (2) between the connecting material marks (4) such as the ridges (4a) of the two connecting materials (2) that are accurately positioned and arranged. Arrange them, and connect the two flat roof tiles (1) lined up in the width direction by butting them together,
This is completed by adjoining and repeating this sequentially from the eaves side to the ridge side. Connecting material (2)
Is parallel to the abutting portion of two adjacent flat tiles (1) that are abutted in the width direction (that is, the result of arranging the connecting member (2) at a right angle or substantially a right angle to the flat tile (1). As). This state is shown in a plan view of relevant parts in FIG.

As shown separately and enlarged in FIG. 4, the surface portion of the non-exposed portion (1a) of the flat roof tile (1) on which one end of the connecting member (2) on the eave side is placed. It is possible to form a recess (6) in which one end of the connecting material (2) can be accommodated. The formation of the recess (6) includes
The connection member (2) can be arranged more easily. That is, one end of the connecting member (2) on the eaves side is accommodated by being inserted into the inside of the recess (6), etc., whereby the positioned position does not shift and the end of the flat roof tile (1) on the ridge side is accommodated. It can be placed on the non-exposed portion (1a), and the connecting material (2) can be fixed to the roof together with the flat roof tile (1) by a fixture (5) such as a nail. . Then, not only the construction becomes easier, but also the construction accuracy is improved.

Further, as described above, the connecting member (2) causes water, which is easily infiltrated at the end of the flat roof tile (1), to flow toward the eaves side of the roof toward the surface of the flat roof tile (1) for drainage. Since it is a member that also has a draining function and can also be used as a drainer, in order to make the draining function work more effectively, the connecting member (2) is shown in an enlarged view in FIG. Further, as shown in FIG. 5, the drainage ridge (7) can be provided so as to project upward.
The drainage ridges (7) are provided in the longitudinal direction of the connecting material (2). As described above, the connecting member (2) is arranged at a right angle or a substantially right angle with respect to the flat roof tile (1), so that the drainage ridges (7) are also flat roof tiles (1).
Right angle or almost right angle to the flat roof tile (1)
On the other hand, the rainwater that tries to infiltrate from the lateral or diagonal direction can be blocked by this drainage ridge (7). Even if it cannot be stopped, rainwater that has infiltrated due to the roof slope can be prevented. It can be smoothly discharged to the eaves side of the roof along the ridges (7) for draining water.

A plurality of such drainage ridges (7) can be provided as shown in FIG. 5, for example.
In this case, the drainage ridges (7) located inside are connected at one end on the ridge side of the connecting member (2) to have a U-shape in a plan view, and also a fixture (5) such as a nail. It is also possible to arrange so as to avoid. The ridge (7) for draining, which is U-shaped in plan view, is effective in blocking the invading water without directing it to the ridge side. As described above, since the connecting material (2) is made of metal and can be manufactured by sheet metal working, the ridge (7) for draining water in this case is used.
Is easy to form.

On the other hand, the ridges (7) for draining water in the connecting member (2) are the unexposed portions (1) of the flat roof tile (1).
It is premised on the concave portion (6) formed in a).
This is because the flat roof tile (1) is arranged on the connecting member (2), so that the flat roof tile (1) is overlapped by the roofing by the drainage ridges (7) projecting upward in the connecting member (2). This is because there will be a gap between the upper and lower flat roof tiles (1) corresponding to the height of the drainage ridges (7), and there is concern that rainwater may enter. Therefore, the connecting material (2)
When the convex strip (7) for draining water is provided on the floor, one end of the connecting material (2) on the eaves side is provided in the non-exposed portion (1a) of the flat roof tile (1) in order to prevent such a gap. A concave portion (6) is required on the surface portion on which the portion is placed, and moreover, the depth of the concave portion (6) is such that the ridge (7) for draining the connecting material (2).
Must be equal to the height of. As a result, when the connecting member (2) is arranged, the drainage ridges (7) are housed inside the recesses (6) formed in the non-exposed portion (1a) of the flat roof tile (1), The adverse effect of providing the drainage ridges (7) is eliminated. That is, the waterproof property is ensured, and the drainage property when rainwater invades is improved.

The eaves side drainer (8) is provided on the eaves side portion (10) of the roof surface, as shown in FIG. 1 (b). As shown in (a) of FIG. 1, the eaves drainer (8) is formed to be longer than the lateral width of the flat roof tile (1). For example, in the case of FIG. 1 (a), assuming that the width of the flat tile (1) is A, the eaves drainer (8) has the same length as the flat tile (1).
The length is twice or more as long as the width A of A.

Moreover, as shown in FIGS. 2 (a) and 2 (b), the ends of the eaves-side drainer (8) are superposed on each other. For example, in the case of (a) to (b) of FIG. 2, in the eaves drainer (8), the side end portion (11) of the eaves drainer (8) on the right side is a part that is overlapped and hidden. ). And in the case shown in FIG. 3, the right side end (11) of the eaves drainer (8) is previously provided as a hidden margin.

The alignment mark (9) indicates the mounting position of the connecting member (2) as shown in FIG. 1 (a). This alignment mark (9) includes the seam portion where the ends of the eaves drainer (8) are overlapped with each other, and the eaves drainer (8) of the same eaves at a constant span.
It is provided in. In the case shown in FIG. 1 (a), since the width of the flat roof tile (1) is A, the span of the alignment mark (9) is also A. .
