[Industrial applications]

 This invention improves a projection provided on the bottom side of a flat roof tile on the bottom side of a roof tile called "Ken Ken", and provides a roof tile in which a recess for accommodating the tip of the projection is provided for each of the projections. The present invention relates to the provision of flat roof tiles that enable stacking and binding in a particularly stable packing form and stable standing on a truck when firing roof tiles.

[0002]

[Prior Art]

 There is a flat roof tile that has a substantially rectangular shape and is provided with a stepped shape in which the water receiving ear is dropped along the edge in the flow direction. In this type of flat roof tile, a protrusion commonly referred to as a rear ken is provided on the bottom side, that is, the back surface on the upper side of the roof when it is roofed. This protrusion called a butt ken has a ridge with a small protrusion width protruding from the butt side of the flat roof tile, and with this ridge face placed on the tile tile, The engaging piece portion further projecting from this raised portion can be hooked on the upper side of the roof tile or the like.

[0003]

[Problems to be solved by the device]

 However, in such a conventional flat tile, the surface of the protruding portion of the protrusion is located at the roofing level of the roof when this roofing is roofed. The engaging piece portion of the protrusion is configured to protrude.

As a result, when the roof tiles are stacked, the engaging piece portion of the protrusion called “buttock” comes into contact with the surface of the roof tile located below when stacking the roof tiles, and the roof tiles are stacked with each other. The roof tiles that are stacked by creating a gap that corresponds to the difference between the protruding part of the protrusion protruding in this step shape and the engaging piece part have a large stacking height on the side of this buttocks on the side of the head. There is an inconvenience of a small deformed packing, a load collapses when loading with such a packing, and the stacked roof tiles are damaged, so it is not possible to stack and bind in such a state It was

From this point of view, the engagement piece portion having a large protrusion width of the protrusion, which is generally called “butt ken”, is shifted to the side of the roof tile to be stacked, that is, the surface of the protrusion portion of the protrusion is changed. Stacking The roof tiles were stacked and bound so that they touched the front side of the roof tiles. However, in such a method, since the roof tiles are sequentially displaced and the sides have a roughly rhombic shape, the load tends to collapse during loading, and the load tends to be damaged during loading or transportation. Had.

[0006] In addition, unlike flat tiles of this type, when flat tiles of this type are erected on a trolley during firing, it is difficult to erect them on the trolley, especially at the tail side of the tiles. It was necessary to take a fall prevention measure with a metal fitting one by one, and it took a lot of work to load the trolley during firing.

Further, in this type of flat roof tile, since the above-mentioned protrusion has extremely different thickness portions and thin thickness portions, it is easy to generate a thick portion having a different press pressure, and In some cases, a difference in shrinkage was apt to occur during drying and firing, and a large amount of defective products having distortions, cracks and the like were produced.

In view of the inconvenience of such a conventional flat roof tile, the present invention has a good packing appearance when stacked and bundled, and has a shape suitable for stable loading, and the loading standing on the trolley during the firing process. The objective is to provide a flat roof tile that is easy to install and has less shrinkage distortion and cracks.
