Description

[Detailed description of the invention] a. Purpose of the invention (industrial application field) The roof tile according to this invention is used for roofing ordinary Western-style houses.

(Prior Art) Roof tiles made of press-molded mortar or clay are widely used to cover the roofs of ordinary houses.

The basic shape of conventional roof tiles is that most of them are curved so that the center of the top surface is concave, and when a roof is covered with multiple tiles, the entire roof looks wavy. That's what I was doing. The basic shape of this conventional roof tile is almost the same for roof tiles used to cover the roofs of Japanese-style houses and roof tiles used to cover the roofs of Western-style houses, but the colors vary between Japanese and Western styles. The current situation is that there are only a few.

(Problem that the invention aims to solve) However, simply changing the color of roof tiles that have been used as Japanese-style tiles for a long time is not necessarily suitable for roofing purely Western-style houses.

In addition, conventional roof tiles, which are curved as a whole, have to be thick in order to maintain their strength, which not only adds to their weight, but also makes it difficult to fit many tiles into gaps when stored in a warehouse. Since they cannot be stacked without being stacked, there is an inconvenience in that they require storage space.

In order to solve the above-mentioned inconveniences, the basic shape of roof tiles can be made flat, but if flat roof tiles are lined up on the roof with no gaps, the roof surface will be too simple and will not look good. For this reason, it is conceivable to arrange flat roof tiles on the roof with gaps between them, but if such gaps are used, rainwater that flows into these gaps will be damaged during strong winds. There is a possibility that the water will flow backwards and overflow from the upper edge of the tiles.

The roof tile of the present invention eliminates all of the above-mentioned disadvantages.

b. Structure of the invention (means for solving the problem) The roof tile of the invention has a locking part for locking the roof tile to the tile beam on the back side of the upper edge of the main body part, which has a flat surface, and a locking part on the lower edge of the main body. A small protrusion is formed at the center of the back surface of each part.

Further, a receiving plate portion whose surface is lower than the surface of the main body portion is formed at one side edge of the main body portion. A first bank portion whose surface position is approximately equal to the surface position of the main body portion is formed at the upper end edge of the receiving plate portion. Further, on the edge of this receiving plate part, there is a second bank part of low height whose upper end is continuous with the above-mentioned first bank part, and in the center of the receiving plate part, the upper end is connected to the above-mentioned first bank part. A third bank part is formed which is spaced apart from the lower surface of the part and whose height is slightly higher than the second bank part. Therefore, a first groove is formed between the main body part and the third bank part, and a second groove is formed between the second and third bank parts. Both the first and second grooves are open at their lower ends, and their upper ends communicate with each other through a communication path between the upper end of the third bank and the lower surface of the first bank.

Furthermore, a cover plate part is formed on the other side edge of the main body part, the surface of which is located on the same plane as the front surface of this main part, and the back surface of which is recessed than the back surface of the main part. A locking protrusion whose width is narrower than the width of the first groove by the width of the small protrusion is formed on the back surface of the edge.

(Function) When covering a roof with the roof tiles of the present invention constructed as described above, just as when using conventional roof tiles, a rod called a tile beam is placed horizontally on the sloping roof surface. Secure with nails.

In the roof tile of the present invention, the locking part on the upper edge of the back surface is locked to such a tile crosspiece, and the roof surface is covered with the ends of the tiles adjacent vertically and horizontally overlapped with each other.

At this time, for roof tiles that are adjacent to each other on the left and right, place the locking protrusion on the back of the edge of the cover plate of one roof tile inside the first groove on the top surface of the receiving plate of the other roof tile. While fitting together, a gap is left between the edge of the covering plate portion of one roof tile and the edge of the main body portion of the other roof tile.

Also, vertically adjacent roof tiles are shifted in phase by an anti-pitch, and the lower part of the upper roof tile is placed on the upper part of the lower roof tile. In this state, the small protrusion at the lower end of the back surface of the upper roof tile is fitted into the gap between the lower roof tiles.

When a roof is covered with tiles in this manner, rainwater that falls on the top surface of each roof tile during rainfall flows alternately between the top surface and the gaps between the adjacent roof tiles on the left and right, and is sent into the gutter.

When strong winds blow against the roof surface during rain, the rainwater flowing down along the gap will flow back upward through the first groove located below this gap, but it will not reach the upper end of this first groove. When it reaches the stage, the flow is stopped by the first high bank, passes through the communication passage to the second groove, flows down this second groove, and flows out onto the upper surface of the main body of the tile below.

(Example) Next, the present invention will be explained in more detail while explaining the illustrated embodiment.

Figures 1 to 8 show the first embodiment of the present invention, with Figure 1 being a front view, Figure 2 being a back view, Figure 3 being a view from below Figure 1, and Figure 4 being a view from below. A- in Figure 1

The lower edge of the main body part 2 of the roof tile 1 made by press-molding mortar or viscosity is formed into an arc shape, and the upper surface of this main body part 2 is formed flat. Also, on the back side of the upper edge of this main body part 2, roof tiles 1 are attached to tile crosspieces nailed onto the roof surface.
Locking portions 3, 3 for locking are formed.
Numeral 4 is a nail hole provided near the locking portions 3, 3, for inserting a nail for fixing the roof tile 1 onto the roof surface. Further, on the surface of the upper edge of the main body portion 2, at a position opposite to the locking portions 3, 3, there are formed recesses 5, 5 large enough to allow the locking portions 3, 3 to fit therein. . These recesses 5, 5 are necessary for press-molding mortar etc. to form the locking parts 3, 3 in a protruding manner, and in addition, when stacking a large number of roof tiles in a warehouse etc. It also has the role of fitting the roof tiles 3 and 3 inside to prevent unnecessary gaps from being formed between vertically adjacent roof tiles. Furthermore, the main body part 2
A small protrusion 6 as shown in detail in FIG. 5 is formed on the back surface of the central portion of the lower edge, and a recess 7 of approximately the same size as the small protrusion 6 is formed on the opposite surface of the small protrusion 6.
This recess 7 is also necessary for forming the small protrusion 6 to protrude, but when stacking a large number of roof tiles, the small protrusion 6 is fitted inside so that the positions of vertically adjacent roof tiles do not shift. At the same time, make sure that no unnecessary space is created.

Further, a receiving plate portion 8 whose surface is lower than the surface of the main body portion 2 is formed on the left side edge of the main body portion 2 . This receiving plate part 8 is located on the lower side when the side parts of roof tiles adjacent to each other on the left and right are overlapped, and the upper surface has three bank parts 9 to 3 of different heights. 11 is formed. this house,
A first bank portion 9 formed at the upper edge of the receiving plate portion 8
is the highest and is formed up to a height that almost coincides with the surface of the main body portion 2. Next, the second bank part 10 formed at the side edge part of the receiving plate part 8 is formed at the lowest point, and the upper end part of this second bank part 10 is located outside the first bank part 9. Continuous to the bottom side of the end. Also, the height h of this second bank portion 10 (Fig. 6)
A third bank part 11 having a height H slightly larger than that (h<H) is formed approximately at the center of the receiving plate part 8, and its upper end is connected to the first bank part 9.
It is slightly separated from the lower side of the . Therefore, a first groove 12 is provided between the side edge of the main body portion 2 and the third bank portion 11, a second groove 13 is provided between the second and third bank portions, and a second groove 13 is provided between the second and third bank portions. Both first and second grooves 1 are provided between the lower surface of the bank portion 9 and the upper end of the third bank portion 11.
A communication path 14 that communicates the upper ends of 2 and 13 with each other.
are formed respectively.

Furthermore, a cover plate part 15 is formed on the right side edge of the main body part 2 to cover the upper surface of the receiving plate part 8 of an adjacent roof tile when roofing the roof. The front surface of the cover plate section 15 is flush with the surface of the main body section 2, but the back surface is recessed from the back surface of the main body section 2.
Furthermore, a locking protrusion 16 having a width narrower than the width of the first groove 12 on the upper surface of the receiving plate part 8 is formed on the back surface of the edge portion of the cover plate part 15. The width of this locking protrusion 16 and the width of the first groove 12 are determined as follows. That is, the roof tiles 1, 1 adjacent to the left and right
As shown in FIG. 8, the receiving plate part 8 and the cover plate part 15 are placed with the cover plate part 15 facing upward, and the locking protrusion 16 on the lower edge of the cover plate part 15 is attached to the receiving plate part. When the first groove 12 on the upper surface of 8 is fitted on the side far from the main body part 2, the small protrusion 6 is fitted between the edge of the cover plate part 15 and the edge of the main body part 2. A flexible gap 17 is formed.

Note that grooves 18 to 21 that are long in the vertical direction are formed on the lower surface of the main body portion 2, which has a flat upper surface, in order to reduce weight. As shown in Figure 7, a large number of roof tiles 1, 1
When combined, the roof tiles 1, 1 located on the lower side
It is positioned above the upper end of the gap 17 between the two.

When covering a roof with the roof tiles of the present invention constructed as described above, rods called tile beams are nailed horizontally onto the sloping roof surface in the same way as when using conventional roof tiles. Then, the locking parts 3, 3 on the upper edge of the back surface of each roof tile 1, 1 are locked to the upper edge of such a tile crosspiece, and as shown in FIGS. The roof surface is covered with the ends of the roof tiles 1, 1 overlapped with each other.

At this time, as for the left and right adjacent roof tiles 1, 1, as shown in FIG. 1 and the edge of the covering plate part 15 of one roof tile 1 and the edge of the main body part of the other roof tile 1. Leave a gap 17 between them.

Further, the vertically adjacent roof tiles 1, 1 are shifted in phase by half a pitch as shown in Fig. 7, and the lower part of the upper roof tile 1, 1 is placed on the upper part of the lower roof tile 1, 1. do. In this state, the small protrusion 6 at the lower end of the back surface of the upper roof tiles 1, 1 is fitted inside the gap 17 formed between the lower roof tiles 1, 1.

When the roof is covered with a large number of tiles in this way, the rainwater that falls on the top surface of each roof tile 1, 1 during rain is absorbed by the gap 17 between this top surface and the adjacent roof tiles 1, 1 on the left and right. , 17 alternately and are fed into the gutter installed at the eaves of the roof.

When a strong wind blows against the roof surface during rainfall, the rainwater flowing down along the gaps 17, 17 is pushed by the wind and flows back upward through the first groove 12 located below the gaps 17, 17. However, when this rainwater reaches the upper end of the first groove 12, its flow is blocked by the high first embankment 9 and flows through the communication path 14 leading to the upper end of the first groove 12. It moves to the second groove 13 adjacent to the first groove 12 and flows down this second groove 13 to the main body part 2 of the roof tile 1 adjacent below.
It flows out to the center of the upper surface. The wind that has reached the upper end of the first groove 12 flows upward along the groove 19 at the center of the back surface of the upper roof tile and is diffused.

Second bank portion 10 defining the outside of the second groove 13
Since the height h is slightly (about 1 m/m) lower than the height H of the third bank part 11 that defines the inside, the upper surface of the second bank part 10 comes into contact with the lower surface of the cover plate part 15. Instead, rainwater flowing down the second groove 13 seeps out of this groove 13 due to capillary action.
The lower roof surface of each roof tile 1, 1 will not get wet.

In the case of the first embodiment described above, the lower edge of the main body part 2 is formed into an arc shape, but the shape of this part can be arbitrarily selected, for example, as shown in FIG. It can be rectangular or linear as shown in FIG. Also, main body part 2
The receiving plate portion 8 and cover plate portion 15 formed on both sides of the plate may be reversed left and right.

c. Effects of the invention The roof tile of this invention is constructed as described above, but its basic shape is flat and matches the design of purely Western-style houses.It not only saves storage space but also adds accents. For this reason, gaps are provided between adjacent tiles, and rainwater does not leak through these gaps.
