Description

[0001]
BACKGROUND OF THE INVENTION
The invention of this application relates to a flat roof tile. More specifically, the invention of this application is the same shape even if it is turned upside down, and can be divided into two equal parts at the center of both left and right sides, making it difficult to produce waste materials. The present invention relates to a flat roof tile that can drain rainwater that may turn into a material in the eave direction.
[0002]
[Prior art]
Tile used as a roofing material for a house is a major player in the appearance design of the roof, and has functions such as reducing rain noise and enhancing the waterproofness of the roof. As one of them, a flat roof tile (21) as shown in FIG. 6 has been recently proposed.
[0003]
Even if this flat tile (21) is one kind, it is possible to store the eaves. For example, a so-called starter tile arranged on the eaves of the roof is a virtual that passes through the center of the left and right ends of the flat tile (21). Two pieces of the same shape can be obtained by dividing into two along the line (22), and the flat roof tile (21) can be arranged as the first-stage roof tile on the starter thus obtained. it can. From the second stage onward, the flat roof tile (21) can be lifted up to the building side and tiled. For this reason, the flat roof tile (21) facilitates the accumulation of roof tiles and is also effective in reducing building waste.
[0004]
Such a flat roof tile (21) has a horizontally long rectangular shape in plan view so that it is the same shape even if it is turned upside down, and usually on the surface portion (23) with respect to the virtual line (22). A plurality of non-penetrating nail holes (24) are provided at symmetrical positions.
[0005]
[Problems to be solved by the invention]
However, the following problems to be improved are found in the flat roof tile (21) shown in FIG.
[0006]
FIG. 7 is a cross-sectional view of the main part showing the construction state of the flat roof tile (21), but rainwater in the wind and rain is overlapped vertically with two flat roof tiles (21), even if enough footing is taken. May intrude through a slight gap between them, and may overflow from the surface of the lower flat roof tile (21) to the ridge side. Since the flat roof tile (21) shown in FIG. 6 has a horizontally long rectangular shape in a plan view, the rainwater overflowed as described above is caused by roofing of the flat roof tile (21) and the underlaying material (25). It tends to collect on the eaves side of the gap (26) formed between them, and hardly flows down in the eave direction along the surface of the lower covering material (25). Rainwater collected in this way leaks into the back of the shed, causing rain leakage, or staying for a long time without leaking, causing condensation or being absorbed by the flat roof tile (21), resulting in a decrease in strength, etc. I invite you.
[0007]
The invention of this application was made in view of such circumstances, and it is the same shape even if it is turned upside down. It is an issue to be solved to provide a flat roof tile that can drain rainwater that may turn from the surface to the underlayer under wind and rain in the state.
[0008]
[Means for Solving the Problems]
In order to solve the above problems, the invention of this application has a horizontally long and point-symmetrical shape, and can be divided into two equal parts along a virtual line connecting the centers of the left and right ends. Notches are provided on both upper and lower sides across the wire, and waterproof and alignment members for waterproofing and alignment are provided in the area up to the nail hole with the same width up and down across the virtual line. A flat roof tile (Claim 1) is provided.
[0009]
In the invention of this application, the notch is vertically long, and a slit shape is formed between left and right flat roof tiles adjacent to each other by roofing (Claim 2), and recesses are provided at both upper and lower ends. Each of the embodiments has a shape of a half of a recess (Claim 3).
[0010]
Hereinafter, the flat roof tile of the present invention will be described in more detail with reference to the drawings.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a plan view showing an embodiment of a flat roof tile of the invention of this application.
[0012]
For example, as shown in FIG. 1, the flat roof tile (1) of the invention of this application has a horizontally long and point-symmetric shape, and a virtual line (4) connecting the centers of the left end (2) and the right end (3). It is possible to bisect along. Similarly to the flat roof tile (21) shown in FIG. 6, the flat roof tile (1) of the invention of this application has the same shape even if it is turned upside down, and it is difficult to generate waste material that can be divided into two equal parts in the center in the vertical direction. It is a flat roof tile.
[0013]
A plurality of non-penetrating nail holes (6) can be provided on the surface portion (5) at positions symmetrical to the virtual line (4), for example, at a constant pitch. The reason that the nail holes (6) are not penetrated is that not all the nail holes (6) are nailed when the flat roof tile (1) is fixed to the roof surface in tile roofing, but at least the virtual line (4) This is because the next-stage flat roof tile (1) is overlaid on the nail holes (6) on either the upper or lower side with respect to and may not be nailed.
[0014]
The flat roof tile (1) of the invention of this application is provided with notches (7) on both the upper and lower sides of the left and right ends (2) and (3) with the virtual line (4) interposed therebetween. Note that the flat roof tile (1) has a point-symmetric shape also by the arrangement of the notches (7).
[0015]
2 and FIG. 3 are a plan view and a cross-sectional view of relevant parts showing a construction state of the flat roof tile shown in FIG. 1, respectively. Although the nail hole (6) and the nail are omitted in FIGS. 2 and 3, naturally, there is actually a nail for fixing the nail hole (6) and the flat roof tile (1) at a predetermined position.
[0016]
The flat roof tile (1) of the invention of this application has the above notch (7), and this notch (7) is arranged in the flow direction of the roof in the construction state. Unlike flat roof tiles (21) having a horizontally long rectangular shape, rainwater under wind and rain penetrates through a slight gap between the two flat roof tiles (1) that overlap vertically, and the bottom flat roof tile (1) 2 and FIG. 3 through the gap (26) formed between the flat roof tile (1) and the underlaying material (25) from the notch (7) even if it overflows from the surface of the building to the building side. The underlaying material (25) can be transmitted in the direction indicated by the arrow, that is, the eaves direction, and drained. Rainwater is unlikely to collect in the gap (26), and therefore, it is difficult for water to leak into the back of the rainwater or stay for a long time.
[0017]
The notches (7) provided on the upper and lower sides across the virtual line (4) of the left and right ends (2) and (3) of the flat roof tile (1) of the invention of this application are shaped symmetrically with respect to the flat roof tile (1). As long as it is, the shape is not particularly limited. For example, a vertically long shape as shown in FIG. 1 and FIG. 2 that can form the slit shape (8) between the left and right flat roof tiles (1) (1) adjacent to each other by roofing.
[0018]
Moreover, since the notch (7) is provided at the left and right ends (2) and (3) of the flat roof tile (1), there is no fear of the strength reduction of the flat roof tile (1) due to the formation of the notch (7). When the cutout (7) is provided inside the left and right ends, the cutout (7) is provided on both the upper and lower sides across the virtual line (4) as described above. Therefore, the flat roof tile is aligned along the straight line connecting the cutout (7). (1) is easily broken. There is no concern about such cracks in the flat roof tile (1) of the invention of this application. Moreover, due to the notch (7), for example, as shown in FIG. 2, a sense of secrecy appears in the appearance after raising, which is effective in improving the design of the roof.
[0019]
The flat roof tile (1) of the invention of this application is not particularly limited in the shape of the details as long as it is horizontally long and point-symmetric. The basic shape is rectangular in a plan view as shown in FIG. 1, but as shown in FIG. 4, for example, recesses (9) can be provided at both upper and lower ends. In this case, the notch (7) can have half the shape of this recess (9).
[0020]
Of course, the flat roof tile (1) of the invention of this application shown in FIG. 4 is also similar to the flat roof tile (1) shown in FIG. 1, as shown in FIG. Even if it penetrates through a slight gap between the flat roof tiles (1) and flows from the surface of the lower flat roof tile (1) to the ridge side, the flat roof tile as shown in FIG. Rainwater can be drained along the eaves direction through the gap (26) between (1) and the lower eaves (25).
[0021]
In addition, as shown in FIG. 1, the flat roof tile (1) of the invention of this application is waterproof and aligned with the portion up to the nail hole (6) with a width equal to the top and bottom across the virtual line (4). waterproof alignment members of use (10) is provided. In this case, the central part of the waterproof / alignment member (10) can be lost . This is because the cut-out (7) of the flat roof tile (1) after lifting is located at the notch (11) at the center of the waterproof / alignment member (10), so that the drainage of rainwater by the notch (7) is waterproof. This is because of consideration for preventing the alignment member (10) from obstructing.
[0022]
Of course, the invention of this application is not limited by the above embodiments. It goes without saying that various modes are possible for details such as the size, size, and shape of the flat roof tiles and slits.
[0023]
【The invention's effect】
As explained in detail above, the invention of this application is the same shape even if it is turned upside down. It is possible to drain rainwater from the surface to the eaves that may turn to the underlaying material.
