Description

[0001]
[Technical field to which the invention belongs]
The present invention relates to a flat roof tile that is used in a Western-style building such as a concrete building and does not fly even when beaten by the wind.
[0002]
[Prior art]
FIG. 1 shows an embodiment of this type of conventional flat roof tile 3. Like a normal roof tile, the roof tile is hooked on a pier 1 and driven into a nail hole 2 as shown in FIG. After fixing and arranging the tile side edges in a horizontal row, the next tile 3 was laid so that the bottom of the tile overlaps the tile head of the lower tile so that it is alternated with the lower tile ( (See FIG. 3).
[0003]
As shown in Fig. 3, when the roof tiles are arranged so that the top and bottom tiles are staggered, the rainwater that flows between the tiles flows down to the center of the roof tile on the lower side of the eaves. Although it does not easily cause rain leakage due to intrusion, it has the following problems.
That is, the left edge of the right tile 3b is superimposed and pressed on the right edge of the tile 3a, and the tile head is pressed by the tile bottom of the upper ridge side tile, but the left edge is the left side of the tile on the left. Since it is only placed on the tile receiver 4 at the right edge, strong wind blows from the lower side due to a typhoon or the like, and if the tile is beaten from the left side, there is a possibility of blowing away.
[0004]
Several flat roof tiles have been proposed that do not fly even when strong winds blow. For example, Japanese Patent Application Laid-Open No. 2001-40821, Japanese Patent Application Laid-Open No. 2001-107511, Japanese Patent Application Laid-Open No. 2001-123854, and the like. the recess is proposed flat tiles provided with engaging projections of a hook shape engaging presses a recess in a concave portion on Kawaraatama central, butt the engaging portion of the hook-shaped in the other Kawaraatama central portion There is also known a flat roof tile which is provided and engages with a concave portion formed on the tile bottom surface of the tile to be rolled up so as to press the concave portion.
[0005]
[Problems to be solved by the invention]
Japanese Patent Laid-Open No. 2001-40821 has the following problems.
(1) The tile receiver has a low step so that the right edge of the tile next to the left is placed on top of each other, so that the wall thickness is thin. The thickness of the concave portion is further reduced, and not only the strength of the concave portion is lowered, but also the strength of the whole concave portion tends to be lowered, and there is a margin in the allocation size of the tile when the tile is tiled by increasing the length of the concave portion. If you try to do so, the strength will decrease,
(2) Although a bent portion is provided around the concave portion following the return of water, the flow path in the tile receiver is narrowed for this reason, and the amount of rainwater flowing into the tile receiver is increased by inhibiting the flow of water. There is a risk of overflowing over the water return or bend,
(3) Even if the concave protrusion or the engaging convex part that holds the concave part breaks and loses the function of holding the roof tile, the side edge of the adjacent roof tile overlaps the roof tile support after the roof tile is rolled. That cannot be confirmed just by looking at
Etc.
[0006]
The flat roof tile with a hook-shaped engaging part protruding from the center of the tile head also has an appearance that the tiled roof is damaged because the engaging part protrudes with the tile covered, and the concave part of the tile bottom However, because of the flat roof tile structure, the length in the vertical direction cannot be increased so much that there is a difficulty in that it is not possible to give a margin to the tile allocation dimension.
An object of this invention is to provide the flat roof tile which eliminated said problem.
[0007]
[Means for solving problems]
The invention according to claim 1 is characterized in that an engagement piece projects laterally at the notch at the lower end of the tile receiver, and a hook-like engagement portion that can be engaged with the engagement piece is directed upward at the center of the tile head. The above-mentioned engagement of the tiles that are projected and formed with a notch for engaging the engaging part at the corner of the tile bottom, and when the tiles are rolled up so that the upper and lower roof tiles are staggered Engage with and hold the mating piece and engage with the notch of the tile placed on top of the tile receiver so that the tile placed on the tile receiver covers the engaging part. It is characterized by.
[0008]
According to the present invention, the engaging piece is merely projected on the existing tile receiver, and does not impair the strength of the existing tile receiver, and the engaging piece is within the range of the notch at the lower end of the tile receiver. The roof tiles can be formed relatively long in the vertical direction, allowing for a sufficient margin in the tile allocation dimensions, the flow path of the roof tiles being the same as existing ones, and when looking at the covered roof tiles from below When the engaging part is visible and the engaging part is broken, it can be immediately understood.When the roof tile is covered, the engaging part is covered with a roof tile that is wound upward, and the engaging part protrudes and the appearance is impaired. It has characteristics such as lack of.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 4 shows a flat roof tile 11 according to the present invention, in which a roof tile 12 is formed on the right edge, and the bottom edge of the roof tile has a step shape that is one step lower than the roof tile 12 at the corner of the notch 13. An engagement piece 14 is formed to project sideways, and a hook-like engagement portion 15 that engages with the engagement piece 14 is provided to project upward in the center of the roof tile. In the figure, 16 is a water return formed on the roof tile tray 12, 17 is a nail hole, and when the roof tile 11 is rolled, the nail is struck by hitting the nail through the nail hole 17 to the pier as shown in FIG. 11 is fixed. Reference numeral 18 denotes a notch into which the engaging portion 15 of the tile 11 on the lower left is fitted when the roof tiles are rolled.
[0010]
When spreading the tiles 11, the tiles 11 are arranged in a horizontal row from the eaves side, and the left side edge of the tile 11 adjacent to the right is overlapped on the tile receiver 12, and nails are driven through the nail holes 17 and fixed.
Next, the roof tile 11 is inserted into the tile engagement section 15 with the engagement piece 14 being laid downward, and the roof tile 11 is in a zigzag pattern with the roof tile 12 on the tile receiver 12. The left edge of the adjacent roof tile 11 is overlapped and arranged (FIG. 5).
FIG. 6 shows a state in which the engagement piece 14 is inserted into the hook-shaped engagement portion 15, the engagement piece 14 is pressed by the engagement portion 15, and the tile bottom at the left edge of the right adjacent tile is covered thereon. Show.
[0011]
According to the roof tile of the present embodiment, the roof tile 11 is fixed at the head of the tile by two nails nailed through the nail hole 17, and the engaging portion 15 of the lower roof tile 11 holding the engagement portion 14 at the lower end of the roof tile receiver. The distance from the nail stop position to the position pressed by the engaging portion 15 is longer than that of the roof tile disclosed in Japanese Patent Laid-Open No. 2001-40821 that presses the lower side of the roof tile receiver. That is, since the distance between the support points of the tiles becomes long, the tiles are firmly fixed, and it is difficult for the tiles to be lifted by blowing in the wind. Since it can be laid so that it is flush with the edge of the tile bottom, it does not protrude to the outside, the appearance of the tiled roof is not impaired, the engagement part is damaged, and the tile holder can be pressed It is easy to check or check whether it has been lost (if the engaging part is damaged, the roof tile is replaced), and the roof tile holder is not different from the existing one, so that the strength is lost or water The flow path of the tile is not narrowed, and the engagement piece can be lengthened in the vertical direction within the range of the notch portion at the bottom of the tile receiver, so that the allocation dimension at the time of roofing can be given a margin, etc. The effect of.
