Description

[Detailed explanation of the idea] [Industrial application field]

This invention relates to a flat tile whose width can be freely adjusted when it is installed on a roof.

[Prior art and its problems]

Flat tiles have already been developed in which the upper surfaces of horizontally arranged tiles are laid on the same plane when placed on a roof (Utility Model Application Publication No. 7208, 1929). The flat tiles shown in this publication, which have already been installed, are laid on the roof by overlapping the sides with the horizontally adjacent tiles. That is, the flat tiles are wrapped together at the boundary with the adjacent tiles and then placed on the roof. The lap portion of the flat tile has a lower step portion formed low on one edge, and an upper portion placed on the lower step portion on the other single edge. Figure 1 shows how conventional flat tiles are placed on a roof. This flat tile 1 is roofed by placing the upper mounting part 3 on the lower step part 2 so that the upper surface of the horizontally adjacent flat tile 1 is in the same plane. Flat tiles have a unique, clean, and extremely beautiful aesthetic because the tiles that are lined up horizontally lie on the same plane. However, the biggest drawback of this tile is that the width of the roof cannot be adjusted when it is installed on the roof. The reason for this is that in order to lay adjacent tiles on the same plane, steps are provided at the lap portions of both edges, and these steps are fitted together to form the roof. In order to widen the actual roofing width of tiles, narrowing the wrapping width creates gaps between adjacent tiles. The gap has a very noticeable drawback because the top surfaces are in the same plane. Flat tiles cannot be roofed with wide lap widths. Therefore, although flat tiles have a unique beauty, they have the disadvantage that they require a lot of effort to cover a roof. With ordinary S-shaped slates, the roofing width can be adjusted by changing the lap width with the horizontally adjacent tiles. This is because it causes the tiles to wrap in a state where a step is formed at the boundary with the adjacent tiles. In other words, even if the lap width with the adjacent tile is widened or sandwiched, it will not be noticeable when the roof is covered. On the other hand, flat tiles have a constant lap width with adjacent tiles, and the roof width cannot be adjusted. For this reason, in the past, multiple types of flat tiles with different widths were manufactured to adjust the roofing width, and the overall roofing width could be adjusted using these. In other words, to narrow the roofing width, narrow flat tiles were used. Furthermore, since the width of the flat tiles used to adjust the roofing width varies depending on the roof, multiple types of flat tiles with different widths were manufactured. As a result, the number of types of flat tiles has increased, and manufacturing, inventory, transportation, and construction have become extremely complicated.

[Purpose of this idea]

This invention was developed with the aim of eliminating these drawbacks of conventional flat tiles.The important purpose of this invention is that the width can be adjusted within a certain range, and that it can be cut to create a wider width. Since the width can be adjusted, there is a greater degree of freedom in adjusting the width of a single flat tile than with conventional flat tiles, which are adjusted to a narrow width in advance, and the roof can be laid in the optimal wrap condition to match the roof. To provide a flat tile which can be used as an ordinary flat tile if necessary and can be easily roofed with a small number of types of flat tiles to suit all types of roofs.

[Means for achieving conventional issues]

The flat tile of this invention has the following configuration. (a) To ensure that horizontally adjacent tiles are laid on the same plane, a flat tile has a lower step part 2 on one side that overlaps the adjacent tile, and a lower step part 2 on the other side. It has an overlay part 3 that can be stacked on top. (b) The lower stepped portion 2 is formed lower than the upper surface of the flat tile, and the upper mounting portion 3 is formed thinner by removing the lower surface. (c) The difference in level between the lower step part 2 and the upper surface of the flat tile is made equal to or almost equal to the thickness of the upper part 3. (d) The width W of the upper part 3 is equal to the lower step part 2 so that the roofing width can be adjusted by cutting the edge.
It is characterized by being formed to be wider than twice the width H of.

[Effect]

In the flat tile of this invention, as shown in FIGS. 4 and 5, the end of the upper part 3 is cut to match the roofing width of the tile. By placing the cut upper part 3 on the lower step part 2, it can be wrapped in a fitted state on the adjacent tile. When flat tiles are placed on a roof in this state, the roofing width can be adjusted without creating gaps or steps in the lap area. The upper part 3 is made thinner by removing the lower surface, and can be easily cut to adjust the roofing width. Also, the upper part 3 is made more than twice as wide as the lower step, so the roofing width can be adjusted. Can be adjusted freely.

[Preferred embodiment]

Hereinafter, preferred embodiments of this invention will be described based on the drawings. However, the example shown below is an example of a flat tile to embody the technical idea of this invention, and the flat tile of this invention has the material, shape, structure, and arrangement of the component parts as shown below. It is not structure specific. Various changes can be made to the flat tile of this invention within the scope of the claims for utility model registration. In the flat tile 1 shown in FIGS. 2 to 4, the left upper surface is formed somewhat lower in FIGS. 2 and 4, and a lower step portion 2 is formed in this portion.
The level difference of the lower level difference part 2 is determined to be equal to the thickness of the upper mounting part 3. This is because, as shown in FIG. 4, when the upper part 3 is stacked on the lower step part 2, the upper surfaces of the horizontally adjacent flat tiles 1 are arranged on the same or almost the same plane. On the opposite side of the lower step part 2, that is, on the right side of the flat tile in FIG. 4, an upper mounting part 3 is provided to be stacked on the lower step part 2. On the upper surface of the lower step part 2, there is a running water groove 4 extending vertically so that the rainwater flowing into this part flows down smoothly and does not overflow across the lower step part 2.
is formed. The depth of the water flow groove 4 is preferably determined to be 3 to 8 mm. The flat tile 1 shown in FIG. 2 is provided with two running water grooves 4 in the lower stepped portion 2. It is also possible to form more than two running water grooves 4. The width of the lower step portion 2 is preferably determined to be 40 cm or more. The upper mounting part 3 has a lower surface cut out and is formed thin. Moreover, as shown in FIG.
It is formed wider than the width of the lower step part 2 so that it can be stacked on the lower step part 2 even if one side of the upper mounting part 3 is cut. The wider the width W of the upper mounting part 3 is, the larger the width adjustment amount of the flat tile 1 can be. For example, if the width W of the upper part is twice the width H of the lower step part 2, the upper part 3 can be cut in half and wrapped around the lower step part 2. Therefore, the width of the flat tile of this shape can be reduced to the width of the lower step portion 2. The upper mounting part 3 is formed to be more than twice the width of the lower step part 2. A rainstop protrusion 5 is formed along the upper edge of the flat tile 1. The rainstop protrusion 5 extends to the upper edge of the lower step part 2 at the same height as a whole so that rainwater flowing into the lower step part 2 is not blown upward. A hook-shaped cutout 6 is formed on the opposite side of the lower step part 2 so that the rainstop protrusion 5 of the lower step part 2 is fitted into it. The hook-shaped cutout 6 is provided at the corner of the upper edge of the upper part 3 which is superimposed on the lower stepped part 2 of the adjacent tile. A rainstop protrusion 5 is also formed on the upper edge of the hook-shaped cutout 6, and the rainstop protrusion 5 is formed at the same height over the entire upper edge of the flat tile. The upper mounting part 3 has its corners cut into a hook shape so that even when one side is cut off to adjust the width, the rainstop protrusion 5 of the lower step part 2 of the horizontally adjacent flat tile 1 can be inserted. be done. As shown in FIG. 6, the ridges on the upper edges of the hook-shaped corners of the upper mounting portion 3 are removed. A rainstop ridge 5 can be formed at this corner by gluing the partition wall 7 formed in an L-shape. The rainstop ridges 5 are bonded to the hook-shaped corners of the upper mounting portion 3 using, for example, epoxy adhesive or mortar. The partition wall 7 is made of flat tiles 1 made of mortar, synthetic resin, metal, etc.
is formed separately from the The rainstop ridges 5 are formed to have the same overall height, that is, their entire upper end surfaces are formed in the same plane. However, although not shown, it is possible to form the rainstop protrusion 5 of the lower step portion 2 to be somewhat lower than other portions. The height of the rainstop protrusion 5 is preferably determined to be approximately 3 to 10 mm from the plane portion and approximately 15 to 25 mm from the upper surface of the lower stepped portion.

[Usage condition]

Figures 1 and 4 show the state in which flat tiles are blown onto the roof.
As shown in FIG. In FIG. 4, the flat tile 1 has a lower stepped portion 2 of the side edge and a top portion 3 which are wrapped and arranged side by side, and the upper surfaces thereof are roofed on the same plane. The rainstop ridge 5 of the lower step portion 2 is fitted into a hook-shaped cutout 6 of the adjacent flat tile. The flat tiles arranged horizontally are all stacked on top of the flat tiles placed below, and are roofed in multiple horizontal rows in a staggered pattern. When the horizontal width of one flat tile 1, that is, the roofing width, is to be narrowed, as shown in Fig. 5, one side of the upper part 3 is cut out and the roof is wrapped over the lower step part 2 of the horizontally adjacent flat tile. let The upper part 3 to be cut has a hook-shaped corner as shown in FIG. 6, and an L-shaped partition wall 7 is glued to this hook-shaped portion.

[Effect of the idea]

In the flat tile according to this invention, the width of the upper part placed on the lower step part is twice or more wider than the width of the lower step part. For this reason, the edge of the upper mounting part can be cut off, and the upper mounting part can be wrapped over the lower stepped part to cover the roof. That is, a flat tile in which one edge of the upper part is cut can be roofed in exactly the same way as a flat tile in which the upper part is not cut. Therefore, by changing the cutting width of the upper part, the roofing width of the flat tile can be adjusted freely. Compared to flat tiles that are pre-formed to a certain narrow width, flat tiles with this structure have a wider adjustment range for the width of each tile, and fewer special tiles are used to ensure beautiful roofing on all roofs. It has the advantage of being able to In particular, in the flat tile of this invention, the width of the upper part is specified to be more than twice the width of the lower stepped part. Flat tiles with this structure can be used on almost any roof, and can be laid neatly side by side without using specially shaped narrow flat tiles. The reason for this is that the roofing width of a single flat tile can be narrowed by a width corresponding to the width of the lower step. Flat tiles whose roofing width can be adjusted by the width of the lower step can be used on roofs of ordinary houses without the need for specially formed flat tiles on roofs with a width of 1 to 2 inches or more.
The roofs of ordinary houses are covered with flat tiles that are at least 4 ken wide, and even very special roofs are 2 ken or more wide. Therefore, the flat tile of this invention has the advantage that it can be neatly installed on almost any roof without using a specially formed width-adjusting flat tile. That is, in the flat tile of this invention, the width of the lower step is usually adjusted to 40 to 60 mm. Also, flat tiles are 1
There are 4 to 6 layers in between. That is, the roofing width of the flat tiles is adjusted to a range of 450 mm to 300 mm. For this reason, the ratio of the width of the lower step to the roof width is 1/10~
It becomes 1/5. This means that the width of one flat tile can be adjusted by covering the roof with 5 to 10 flat tiles. The reason for this is that the adjustment range of the roofing width of a flat tile does not exceed the roofing width of one flat tile. Therefore, the flat tile of this invention has the advantage that it can be used on almost all types of roofs, and the roof can be beautifully finished without using specially formed flat tiles. In addition, conventional narrow-width adjustable tiles could not be laid to the same width as regular flat tiles, but the flat tiles of this invention can be installed to the same width as regular flat tiles. It can also be used as Therefore, by reducing the number of width-adjusting flat tiles used, that is, by reducing the use of special flat tiles, we have achieved the great effect of making it possible to cover the roof with flat tiles uniformly, effortlessly, and easily. Realize.
