Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof capable of laying running water pieces of several rows and several columns at a time by brazing a roof tile body in which running water pieces are integrally molded in several rows and several columns at the roofing section. The present invention relates to a stacking method for stacking a plurality of roof tiles in a state where the roof tiles and the substantially flat surfaces are aligned.

2. Description of the Related Art Conventionally, for roofing a roof in the shape of a gable, a ridge, etc., for example, as shown in FIGS. 20 and 21, a sleeve starting tile 50 having an edge rib portion 50a at one end in a row is used. It is used as a roofing start for the laying surface of the roof Y. Next, for example, as shown in FIGS. 24 and 25, use a ground tile 51 that is substantially rectangular in a plane and is provided with protrusions 51a, 51b, 51c and is formed into a substantially S-shaped front surface, or as shown in FIG. The roof tiles 52, which are substantially rectangular in a plane and have substantially symmetrical structure on the side surfaces, and which have ribs 52b and 52c for reinforcement on the front and back surfaces, are used on the front and back surfaces. If necessary, this tile tile 51; 52
On the other hand, the roof tiles are adjusted to a shorter length than the ground tiles 51 and 52 by adjusting the roof tiles, and the roof tiles between the roof tiles adjacent to each other are adjusted to prevent rain. Most of the roof Y is laid by roofing the mating parts 52a and 52a '.

At the end of the roof, the edge rib portion 53 is again formed.
By using the sleeve end tile 53 having a at one end, some kinds of tiles such as the sleeve start tile 50, the ground tiles 51 and 52, the adjustment tile, and the sleeve end tile 53 are used toward the upper ridge N. Sequentially join the mats through the mating section. Furthermore, the roof tiles are laid by connecting the roof tiles to the ridge N at the top. In this case, as the roofing pattern of the roof tiles formed on the entire roof Y, the roof tiles are laid in a lattice pattern or in various patterns such as a zigzag pattern in order to finish the appearance beautifully.

Further, as a material for molding the above-mentioned various roof tiles, in addition to the one obtained by firing clay like the main roof tile, the one that is cured and solidified by compressing cement like the thick cement tile, and the slate roof tile As described above, there are those using asbestos and those using small pieces made of metal thin plates such as copper, aluminum, stainless steel, etc. such as color iron plates.

[0005]

However, the conventional roof tiles described above include the sleeve-starting tile 50 shown in FIG. 21 which is laid at the beginning of the roofing of the roof Y and the sleeve-end roofing tile where the roofing end of the roof Y is laid as shown in FIG. 53, and projections 51a, 51 as shown in FIGS. 24 and 25 for laying most of the roof Y.
b and 51c on the upper surface, and a roof tile 52a, 52a 'having a stepped portion is formed on the front and back surfaces of the left and right side surfaces, which is substantially rectangular in a plane as shown in FIG.
Moreover, several types of roof tiles having different shapes and sizes from the ground roof tile 52 having the ribs 52b and 52c for reinforcement provided on the front and back surfaces of the roof tile are manufactured one by one.

Moreover, since some of these types of roof tiles are laid one by one on the roof road boards by stacking the roofing portions of the adjacent roof tiles together, a large amount of cost is required for production and laying work. It took time and labor, and the work efficiency was low.

Further, in the conventional roof tiles laid by such a method, since the tiles themselves are formed in a small area, if a large roofing area between adjacent tiles is adopted, the rain is surely secured. On the other hand, the area for laying one roof tile on the roof Y is reduced. Moreover, laying a certain roof area using this tile requires a large number of tiles, which is uneconomical. On the other hand, if the roofing area between adjacent tiles is reduced in order to increase the laying area for a certain roof Y, the rain will be reduced and water will leak more easily. The required number of sheets is reduced.

Further, FIG. 24 and FIG. 25, or FIG.
As shown in Fig. 5, the conventional roof tile 5 laying most of the roof Y
1, 52 are, for example, protrusions 51a, 5 to increase the strength.
1b and 51c are formed in a substantially S-shape on the front side and are not flat to easily ensure the levelness, or they are formed in a substantially rectangular plane to form steps on the left and right side mating parts 52a and 52a '. Alternatively, the ribs 52b and 52c for reinforcement are provided on the front and back to form protrusions and recesses on the front and back surfaces of the roof tile main body, and the contact areas of the upper and lower roof tile main bodies that are stacked are small and unstable.

Therefore, before laying on the roof Y,
When the roof tiles are transported to the laying site or stored in a warehouse, as shown in FIG. 26 or FIG. 27, when a plurality of roof tiles are stacked and bound by using a string or tape. The protrusions 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 stacked tiles is small and the contact points are uneven and the horizontal level of the tiles cannot be maintained. Therefore, it is not possible to stack the upper and lower roof tiles in a state where they are substantially aligned with each other, and they may be stacked in a displaced (displaced state) in either the left-right direction or the front-back direction, or rattling may occur. there were. In addition, the roof tiles piled up during transportation to the laying site or during storage will collapse and the string for binding will be unraveled, the roof tile as a product will be easily cracked or chipped, and the storage area of the warehouse will be large. Needed an area.

According to the present invention, by producing the running water piece portions directed to a plurality of ascending rows and descending rows at the same time, it is possible to efficiently lay the roof area for a given roof area without any trouble and cost, and to reciprocate roof tiles. The roofing of the roof tiles is sufficient to ensure rain-proofing, and moreover, it is possible to stack multiple sheets in a state in which they are kept level and in a substantially flat plane. The present invention provides a roof tile and a stacking method for the roof tile, which have a small area for storage in a warehouse and have a strong structure, have high strength, are easy to manufacture, and are inexpensive.

[0011]

In view of the above-mentioned problems, the present invention integrally forms a roof tile body having substantially the same size and the same shape by appropriately arranging the running water piece portions in several rows and several columns, and the running water located in the upper row. The thickness of one piece and the thickness of the running water piece located in the descending line are formed to be substantially equal, and the upper surfaces of the running water piece part located in the ascending line and the running water piece part in the descending line are formed substantially through the stepping step part. A means was adopted that was formed in a substantially flat shape over the entire area, and made it possible to stack a plurality of roof tiles in a substantially flat plane.

Further, according to the present invention, the roof tile main body is integrally molded by arranging the running water piece portions in several rows and several columns through the step portions so that the plurality of sheets have substantially the same size and the substantially same shape, and the roof tile body is integrally molded to form a flat surface. We adopted a method of stacking multiple roof tiles in a substantially matched state.

[0013]

The tile main body integrally molded into a suitable number of rows and a few columns is sequentially laid on the roof at a suitable number of rows and a number of columns to lay a plurality of roofing sections at one time. In addition, a plurality of roof tiles can be stacked in a state where they are substantially aligned with each other in a plane, and can be easily transported and stored in a warehouse or the like.
