[0001]
TECHNICAL FIELD OF THE INVENTION
The invention of this application relates to a flat roof tile. More specifically, the invention of this application relates to an improvement in the sense of incongruity in the roofing of a flat tile that has the same shape even when it is turned upside down and that hardly produces waste material at the center in the vertical direction.
[0002]
[Prior art]
Tile used as a roofing material for houses is a major bearer of the exterior design of the roof, and also has functions such as reducing rain noise and increasing waterproofness of the roof. As one of them, a flat roof tile (21) as shown in FIG. 4 has recently been proposed.
[0003]
Even if the flat tile (21) is of one kind, the eaves can be stored in the eaves. For example, a tile called a starter, which is disposed on the eaves of a roof, is assumed to pass through the flat tile (21) in the vertical center thereof. By bisecting along the line (22), two pieces of the same shape can be obtained, and the flat roof tile (21) can be disposed as the first-stage roof tile on the starter thus obtained. it can. From the second stage on, the flat tile (21) can be roofed to the ridge side and tiled. For this reason, the flat roof tile (21) facilitates the integration of the roofing, and is effective in reducing building waste.
[0004]
Such a flat roof tile (21) has a horizontally long rectangular shape in a plan view so that the flat roof tile (21) has the same shape even when it is turned upside down, and has a surface portion (23) from both horizontal sides (24) and (24). The roofing length (a) and the minimum overlap allowance (b) (usually about 50 mm, and this minimum overlap allowance (b) is, as understood from the construction state shown in FIG. 21) is the length of the portion where the roofing feet overlap), and a plurality of unpenetrated nail holes (25) are provided at a position symmetrical with respect to the above-mentioned imaginary line (22). ). As shown in FIG. 5, the nail hole (25) is not penetrated because the next flat tile (21) is overlapped on the ridge side of the previous flat tile (21) in the roofing, and There is also a nail hole (25) that is not nailed due to being located at the lower part, so that if it is penetrated, waterproofness cannot be secured.
[0005]
[Problems to be solved by the invention]
However, the flat roof tile (21), which has the same shape even when it is turned upside down and is hard to generate waste material at the center in the vertical direction, is expected to be improved in the nail hole (25).
[0006]
This is because, as shown in FIG. 5, the flat tile (21) is nailed and fixed in the nail hole (25) at the time of roofing. (25) must be located at least at least the sum of the roof length (a) and the minimum overlap allowance (b) from both lateral sides (24) and (24) on the surface portion (23) of the flat roof tile (21). Must. However, as a result, the nail head nailed in the nail hole (25) may be exposed. Further, since not all nail holes (25) are nailed, the nail holes (25) that are not nailed may be exposed as they are. The nail hole (25) as well as the exposed nail hole (25) is formed in a conical shape in the manufacture of the flat roof tile (21). (21) Gives an unpleasant feeling to the roof.
[0007]
The invention of this application has been made in view of such circumstances, and has the same shape even when it is turned upside down. An object of the present invention is to provide a flat roof tile capable of improving a sense of discomfort.
[0008]
[Means for Solving the Problems]
The invention of this application, as a solution to the above problems, has a horizontally long rectangular shape in plan view, and can be bisected along an imaginary line connecting the centers of both vertical sides. A plurality of unpenetrated nail holes are provided at a constant pitch in the horizontal direction at positions symmetrical with respect to the imaginary line at a distance of at least the sum of the length of the roof and the minimum overlap allowance from the side, and the nail holes The flat roof tile (Claim 1) is characterized in that the flat roof tile has an elongated hole shape and the bottom surface width is made equal to the outer diameter of the nail head.
[0009]
In the invention of this application, the nail hole located below the imaginary line is gently sloped downward, and the nail hole located above the imaginary line is gently inclined upward from the lower side. (Claim 2), a plurality of recesses having the same shape as the nail holes are arranged in a lattice pattern on the surface from the nail hole to both lateral sides (Claim 3). .
[0010]
Hereinafter, the flat tile of the invention of the present application will be described in more detail with reference to the drawings.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
1A and 1B are a plan view and an AA cross-sectional view, respectively, showing an embodiment of the flat roof tile according to the present invention.
[0012]
For example, as shown in FIG. 1A, the flat tile (1) of the invention of this application has a horizontally long rectangular shape in plan view, and is an imaginary line connecting the centers of both vertical sides (2) and (2). According to (3), it is possible to divide into two. Further, the flat roof tile (1) of the invention of this application has a roofing length (a) and a minimum overlapping margin (b) (normally about 50 mm) from both lateral sides (5) and (5) on the surface portion (4). ), A plurality of unpenetrated nail holes (6) as shown in FIG. 1 <b> at a constant pitch (d) in the horizontal direction at positions symmetrical with respect to the virtual line (3). Is provided. As understood from the above description, the flat roof tile (1) of the invention of this application also has the same shape even when it is turned upside down similarly to the flat roof tile (21) shown in FIG. It is a flat tile that is hard to produce waste materials that can be equally divided.
[0013]
Further, in the flat roof tile (1) of the invention of this application, as shown in FIG. 1 <a>, the nail hole (6) is in the shape of a long hole elongated in the direction of the vertical side (2). As shown in <a> and <b>, the bottom surface width (w) is equal to the outer diameter (R) of the nail head (7).
[0014]
Therefore, in the flat tile (1) according to the invention of the present application, the nail (8) shown in FIG. 2A, which is nailed to the roof surface at the time of roofing, has a nail head (7) having an elongated hole. It falls within (6), and although it is exposed for the time being, it becomes less noticeable. Further, the nail hole (6) that is not nailed has a long hole shape, so that even when exposed, the shadow is less likely to be formed and less noticeable than the conical nail hole (25) shown in FIG. Thus, the flat roof tile (1) of the invention of this application can improve the sense of incongruity of roofing.
[0015]
In the flat roof tile (1) of the present invention, the nail hole (6) is located below the imaginary line (3) shown in FIG. 1 <a>, for example, as shown in FIG. 1 <b>. The nail hole (6) located on the side (corresponding to FIG. 1 <b>) has a lower side from the upper side, and a nail hole (6) located above the imaginary line (3) has the upper side from the lower side. Each of them may be gently inclined (that is, θ ₁ <θ ₂ in FIG. 1 <b>). In this way, since the large angle of inclination (θ ₂ ) is located on the ridge side of the flat roof tile (1) after the roofing, the rainwater which is easily attracted to the overlapping portion of the flat roof tile (1) when the wind is strong is used. 6) can be cut off on the upper side. Further, since the small inclination angle (θ ₁ ) side is disposed on the eaves side, the rainwater flowing on the surface portion (4) of the flat roof tile (1) is easily discharged without collecting in the nail hole (6).
[0016]
Further, in the flat roof tile (1) of the invention of this application, as shown in FIGS. 3A and 3B, the surface portion (4) from the nail hole (6) to both lateral sides (5) and (5). A plurality of recesses (9) having the same shape as the nail holes (6) can be provided in a matrix. By doing so, the nail hole (6) and the concave portion (9) can form the surface pattern of the flat roof tile (1), the nail hole (6) becomes less conspicuous, and the rainwater is attracted in a strong wind. It is more effective in stopping and discharging rainwater. In addition, the flat roof tile (1) is not only bisected at the imaginary line (3), but may be cut along the ridge line at a corner ridge portion or the like. In this case, depending on the cutting method, there is no nail hole (6), or even if the nail hole (6) is present, it is located near the cut end, and it is sufficiently fixed even if nailing is performed in the nail hole (6). There is a concern that a force cannot be obtained or a crack occurs. However, in the flat roof tile (1) shown in FIGS. 3 <a> and <b>, since the concave portion (9) has the same shape as the nail hole (6), the concave portion (9) can also be nailed. The nailing is reliably and easily performed for cutting into an arbitrary shape. There is no need to form a nail hole (6) using a drill or the like.
[0017]
Of course, the invention of this application is not limited by the above embodiments. It goes without saying that various aspects are possible for details such as the size and size of the flat tile and the size, size and pitch of the nail hole.
