Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION Generally, a tiled roof is
Tiles were moved by strong winds to break the roof,
It is necessary to have wind resistance so that the tiles are not blown off.

An object of the present invention is to obtain a flat tile having improved wind resistance when roofed.

[0003]

2. Description of the Related Art The shape of a flat tile (hereinafter simply referred to as a tile) is
It is formed as schematically shown in FIG. 11 (perspective view) and FIG. 12 (plan view), and is put on a roof plate and roofed as shown in FIG. 13 (partial schematic plan view of the roof). 11 to 13, 1 is a generic name of a roof tile, 1 a and 1 b are roof tiles that are laid upward,
Reference numerals 1c and 1d denote tiles of the same shape which are alternately arranged and roofed below the tiles 1a and 1b. Left and right of the roof, up and down (in this specification, the left and right are based on the drawing, the up and down means the up and down along the slope of the roof, the front and back of the tile is the upper part of the roof in the vertical direction and the lower part is the front part Yes.)
Tiles 1a, 1b, 1c, 1d
In the left-right direction, the side edge lower edge 2 formed on the side edge and the side edge covering edge 3 are overlapped, and they are arranged without gaps in the left-right direction of the roof as shown in FIG. In the vertical direction, the rear end upper ridge 4 and the front end lower ridge 5 are engaged, and the rear end lower ridge 6 is hooked on the horizontal rail 7 of the roof. It is arranged so as to cover the direction without gaps and allow rainwater to flow down. Then, a nail 9 passed through a nail hole 8 formed in the rear end upper ridge 4 is driven into the horizontal rail 7 of the roof, and each tile is fixed on the roof plate.

However, merely arranging and fixing the tiles in this way and roofing the roof is vulnerable to strong winds, so it has been considered to improve the wind resistance.

Japanese Patent Application Laid-Open No. 9-88248 discloses one means for improving wind resistance. This means is a fastener 10 made of a thin stainless steel plate (or equivalent) as shown in FIG. 16 (perspective view), and as shown in FIG. 17 (perspective view), And the lower roof tile 1c, which is alternately laid underneath. That is, the hook 10a of the stopper 10 is applied to the upper surface of the lower edge 2 at the side end of the roof tile 1a, and a half of the width of the base 10b of the stopper 10 is attached to the rear lower projection 6 of the lower roof 1c. Apply to the bottom and double tiles 1
The protruding edge 2 of a, 1c and the protruding ridge 6 are elastically sandwiched and connected. The length of the pillar 10c of the stopper 10 is the hook 10a.
The length is such that the pinching can be performed appropriately by utilizing the elasticity of the sheet.

When the upper and lower roof tiles 1a and 1c are sandwiched in this manner, the lower edge 2 at the side end of the upper roof tile 1a is attached to the rear end of the lower roof tile 1c which is nailed and strongly fixed to the cross rail 7. Since it is supported, the roof tile 1a conventionally supported only at the nailed rear end is replaced with the lower roof tile 1c also at the side end.
Will be supported by the fixed part of the tiles, and the state in which each tile is connected and supported in this way will occur on all the tiles,
Wind resistance improves as a whole roof.

[0007] However, even with a roof with improved wind resistance in this way, if it encounters a remarkably strong wind, the tile may be displaced or blown off.

FIG. 18 shows a roof tile 1 caused by a strong wind from the direction a.
An example at the time of a strong wind disaster in which c and 1d are shifted is shown schematically. In the roof tile 1c that was displaced, the rear part 2a of the side edge lower protruding edge 2 was little moved, and the front part 3a of the side edge covering edge 3 was largely moved sideways.

The reason is considered as follows. Roof tile 1
c, 1d each side edge lower edge 2 is connected to the nailed upper part of the lower roof tile (not shown) by a fastener 10 (not shown) and has a larger support than the side edge covering edge 3. The side edge covering edge 3 is easily lifted up because it is not supported by the stopper 10 while it is hard to move even in a strong wind due to the action. Therefore, when the right portion of the roof tile 1c first rises due to the strong wind from the direction a (the right direction in FIG. 18), the nail 9a on the right side among the nails fixing the upper portion of the roof tile 1c is first removed (or the roof tile). (The vicinity of the hole 8 is damaged), and it moves in the direction of arrow b around the upper left part of the roof tile 1c supported by the left nail 9b, which is still supported even though it has slipped out, and further strong winds Subsequently, it is considered that the support of the nail 9b on the left side is lost and the roof tile 1c is blown off. Thus, the tile 1c
When the tile moves, the stopper itself connecting the tile 1c to the lower tile is not fixed to the shingle, so it easily slides together with the tile 1c, and the adjacent tiles 1c and 1d form an inverted V shape. Will open.

In order to prevent the roof from breaking due to the strong wind from the direction a or from the lower right in the direction a, the front part 3a of the side edge covering edge 3 of the roof tile 1c is moved by the arrow b in FIG.
If it is difficult for the tile to move in the direction, it is considered that the initial wind resistance of the tile 1c when the tile 1c is to be moved is improved, the delay in starting the tile to shift and the endurance time until the tile 1c is blown off can be lengthened.

When a strong wind blows from the lower left direction in FIG. 13, as shown in FIG. 19, the lower surfaces of the roof tiles 1c and 1d are pushed by the wind in the c direction, and the lower side edge 2 is elastically moved. The hook stops from the hook 10a (not shown) of the stopper and rotates in the d direction around the nail at the upper right, and the space between the roof tile 1c and the adjacent roof tile 1c opens in an inverted V shape.

[0012]

SUMMARY OF THE INVENTION According to the present invention, two adjacent tiles are prevented from opening in an inverted V shape due to such a strong wind disaster, and the shear movement of the tiles due to a strong wind is prevented at an early stage. To improve the wind resistance of the tile.

[0013]

SUMMARY OF THE INVENTION According to the present invention, a side edge lower edge is formed on one side and a side edge covering edge is formed on the other side, and a rear edge is fixed to a roof plate with nails. The edge and the lower surface of the rear end portion of the flat roof tile that is laid downward, and the flat roof tile that is roofed by being pinched and joined by a fastener, and a side on which a side edge covering edge is formed,
At the front end corners with the side where the side edge lower projection is formed, when the roof is laid on the roof, the adjacent flat tiles engage with each other to be below the left and right overlapping portions of the two flat tiles. A flat roof tile with improved wind resistance, characterized in that a notch and a projection are formed to prevent the opening from opening in an inverted V shape.

[0014]

The cutouts and projections formed in the side corners of the adjacent tiles prevent the overlapping portions of the adjacent tiles from opening in an inverted V shape depending on the direction of the wind. When there is a tendency to be biased, by selecting the side that forms the notch and the protrusion, it is possible to prevent or reduce the strong wind disaster of the roof by suppressing the shear movement of the tile at the time of strong wind at the initial stage .

FIG. 6 is a lower side view similar to FIG. 5 when left and right roof tiles are stacked.

First, a first example will be described with reference to FIGS. A square notch 11 is formed at the lower right corner of the left roof tile 1a, and a protrusion 12 is formed at the lower left corner of the right roof tile 1b opposed thereto. Notch 11 and protrusion 12 are roof tiles 1a and 1b
Is formed at the front end of the roof tile in front of the side edge covering edge 3 and the side edge lower protruding edge 2. The projection 12 engages with the notch 11 when the upper and lower edges 3 and 2 of the roof tiles 1a and 1b are overlapped as shown in FIG. It overlaps with the side edge covering edge 3 as before. The front end face of the projection 12 has the same shape as the front end face of the roof tiles 1a and 1b. When a pattern is applied to the front end face, a continuous pattern is applied to the front end face. To make them look continuous.

In the first example shown in FIGS. 1 to 5, the protrusion 12 is formed above the lower edge 2 at the side end.
As shown in (a) and (b), the projections 12 are formed over the entire thickness of the tile including the lower ridge 5 at the front end of the tile, and the notch 11 is correspondingly formed at the lower part of the front end. It may be formed over the entire thickness of the tile through the ridge 5.

FIGS. 6 and 7 show a second example of the projection 12 of the first example.
Is a triangular prism protrusion 12a whose side surface is triangular, the square notch 11 of the first example is a triangular notch 11a, and the side surface engaging with this notch is a triangular notch 11a. Is the same as

When the notches 11, 11a and the projections 12, 12a are provided as described above, the notches and projections engage as shown in FIGS.
When the tile is about to be moved in the direction b by the wind from the direction of the arrow a or the lower right, the adjacent tile has the effect of adding resistance to the movement and preventing the tile from shifting.

Therefore, the tile is lifted by the strong wind from the right or the lower right in FIG. 18, and the movement of the tile is suppressed at the initial stage when the tile is about to be rotated in the direction of arrow b, thereby preventing the tile from moving. it can.

When the wind blows from the direction c in FIG. 19, the wind blows from the front side of the roof 1d under the roof to lift the roof and pushes the front end face of the roof to rotate the roof 1d in the direction d. As a result, the space between the roof tile 1c and the adjacent roof tile 1c is opened in an inverted V shape. 9, a notch 11c similar to that of FIG. 1 is provided at the front corner of the lower edge 2 of the side end, and a projection 12c engaging with the notch 11c is provided at the front corner of the edge 3 covering the front end. By this formation, it is possible to prevent the tiles 1c and 1d from opening in an inverted V-shape due to the strong wind in the direction c in FIG. 19, and to prevent the tiles from slipping at the initial stage.

As described above, according to the present invention, in the overlapping portion of the tiles arranged side by side in a strong wind, the front ends of the both tiles are prevented from opening more than the rear end, thereby preventing the tiles from sliding. Notches 11 and projections 12
Can be changed in shape, size, etc. within a range that can achieve this purpose. Further, in the case of the roof tile in which the lower edge of the side end and the edge of the side end cover are formed left and right opposite to those in FIG. 1, the above left and right are cut out to form the protrusion.

[0023]

According to the present invention, notches and protrusions are provided at the front end corners of the tiles, which are overlapped with the side edge covering edges and the lower protruding edges of the tiles to be tiled side by side, in consideration of the wind direction in the land, and are engaged. Therefore, it is possible to prevent the tiles from rotating and the front ends of the right and left tiles opening from the rear end and starting to move in the early stage when the wind is strong. The wind resistance of the roof tile can be further improved in combination with the function of the tool.
