DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof in which several rows and several rows of running water pieces can be laid at a time by laying a tile body in which several pieces of running water are integrally molded in a suitable number of rows. The present invention relates to a tile and a stacking method of stacking a plurality of tiles in a state where the tiles are substantially flat.

[0002]

2. Description of the Related Art Conventionally, in order to tile a roof having a gable, ridge, or the like shape, for example, as shown in FIG. 20 and FIG. 21, a sleeve start tile 50 having an edge rib portion 50a at one end in the same row is used. Used as the beginning of roofing on the laying surface of roof Y. Then, for example, as shown in FIGS. 24 and 25, a ground tile 51 formed in a substantially S-shaped front surface provided with projections 51a, 51b, 51c in a substantially rectangular plane is used, or as shown in FIG. A roof tile 52a, 52a 'having a substantially rectangular plane and a substantially symmetrical structure on the side surface, and reinforcing ribs 52b, 52c protruding from the front and back surfaces is used on the front and back surfaces. If necessary, this ground tile 51; 52
In contrast, the adjustment length of the tiles is adjusted by mixing and using the adjustment tiles having a shorter rectangular shape than the ground tiles 51 and 52, and the adjacent tiles in the same row are tiled between the tiles for rain. That is, the roof Y is laid by way of the joints 52a and 52a '.

[0003] Then, the end of the roofing is again edge rib portion 53
By using the end-of-sleeve tile 53 having a at one end, several kinds of tiles such as the start-of-sleeve tile 50, the ground tiles 51, 52, the adjustment tile, and the end-of-sleeve tile 53 are used toward the upper ridge N. The roofing is sequentially performed via the roofing section. Further, a roof tile such as a gable is laid by connecting ridge tiles to the ridge N at the top. In this case, as the tiled pattern of the tiles formed on the entire roof Y, the tiles are laid in various types of patterns such as a lattice shape or a staggered shape in order to finish the appearance beautifully.

As materials for molding the above various types of roof tiles, in addition to fired clay like this roof tile, compressed and cured and solidified cement like thick cement roof tile, and slate roof tile As described above, there have been those using asbestos and those formed using small pieces made of a thin metal plate such as copper, aluminum, and stainless steel such as a color iron plate.

[0005]

However, the above-mentioned conventional tiles have a sleeve start tile 50 shown in FIG. 21 laid at the beginning of the roof Y, and a sleeve end tile laid at the end of the roof Y as shown in FIG. 53 and projections 51a, 51 as shown in FIGS. 24 and 25 for laying most of the roof Y.
The roof tiles 51a and 52a 'having a substantially S-shaped front tile having upper surfaces b and 51c on the upper surface thereof, and roofing portions 52a and 52a' having step portions are formed on the front and rear surfaces of the left and right sides in a substantially rectangular plane as shown in FIG.
In addition, several types of tiles having different shapes and dimensions from the ground tile 52 in which reinforcing ribs 52b and 52c are provided on the front and back surfaces of the tile are manufactured one by one.

In addition, since some of these types of tiles are laid one by one on a roof road board by shingling the tiled portions of adjacent tiles, a large amount of cost is required for production and laying work. It took a lot of time and labor, and the work efficiency was low.

In a conventional roof tile laid by such a method, the tile itself is formed in a small area. Therefore, if a large area is taken between adjacent tiles, the rain can be reliably performed. On the other hand, the area laid on the roof Y for one tile is reduced. Moreover, laying a fixed roof area using these tiles required a large number of tiles, which was uneconomical. Conversely, if the roofing area between adjacent tiles is reduced by trying to increase the area laid on the fixed roof Y, rainfall will decrease and water will leak easily. The required number of sheets used decreases.

FIG. 24 and FIG. 25 or FIG.
As shown in FIG.
For example, the projections 51a, 5
1b and 51c are formed in a substantially S-shaped front and are not flat so that horizontality can be easily ensured, or steps are formed in the roofs 52a and 52a 'on the left and right side surfaces in a substantially rectangular plane. In addition, the contact area between the upper and lower tile bodies stacked one on top of the other is reduced due to uneven surfaces formed on the front and back surfaces of the tile body by reinforcing ribs 52b and 52c protruding from the front and back surfaces, thereby making the tile body unstable.

Therefore, before laying on the roof Y,
When the tiles are transported to the laying site or stored in a warehouse, as shown in FIG. 26 or FIG. 27, a plurality of tiles are stacked and bound using a string or tape. The projections 51a, 51b, 51c and the reinforcing ribs 52
Since the uneven surfaces such as b and 52c contact the upper surface or the lower surface of the tiles to be stacked, the contact area between the tiles to be stacked is small, and the contact points are uneven and the level of the tiles cannot be maintained. As a result, the upper and lower roof tiles cannot be stacked in a state where they are substantially coincident with each other, and may be stacked in a displaced (displaced) direction in either the left-right direction or the front-rear direction, or rattling may occur. there were. In addition, the tiles stacked one upon another during transportation or storage to the laying site, etc. may collapse and break the string for binding, and the tiles as a product may be easily broken or chipped, and the storage area of the warehouse etc. is large. Needed area.

The present invention makes it possible to efficiently lay a fixed roof area without trouble and cost by manufacturing running water pieces for a plurality of ascending and descending sheets at the same time. It is possible to stack a plurality of sheets while they are being transported or stored in a warehouse so that they can be stacked in a substantially flat plane while maintaining the horizontality. Les does not have, also there is no cracking and chipping, the teeth
Structure robust high strength in an area smaller storage duck warehouse, further, to manufacture it provides an easy and inexpensive roof tiles and superimposed stacking method.
