Description

[Detailed description of the invention] This invention relates to a roof tile formed by pressing a steel plate.

Roof tiles that are made of steel plates are stronger than regular roof tiles and can withstand permanent use, but because they are plate-shaped, they do not weigh as much when stacked on top of each other, making them look less attractive than regular roof tiles. Despite their superior strength, there was resistance to using steel plates as roof tiles.

This idea was conceived based on the above considerations, and even if the steel plate tiles are extremely thin compared to regular roof tiles, they can be made to have a certain thickness to improve their appearance. In addition, we have developed a new steel plate roof tile that has a new structure that allows it to withstand strong winds and prevent water leakage due to rainwater seepage during strong winds and rain. This is what we are trying to provide.

This invention for the above purpose uses a substantially square steel plate as a base material, bends the base material high at the rear at required intervals determined as the length of the roofing foot, and creates exposed portions of approximately equal length through stepped portions. The non-exposed part and the rear part of the non-exposed part, which is significantly shorter in length than the non-exposed part, are divided in order, and a plurality of ribs extending over each part are formed convexly on the front side, and the three sides of the exposed part side of the base material are On the back side, bend the non-exposed part and both sides of the rear part of the non-exposed part and the rear end side of the rear part of the non-exposed part to the front side to form downward and upward side pieces around the base material. The gist of this is that a rain protection projection is provided at the center of the rear part, extending to the border with the non-exposed part.

This invention will be explained in detail below using illustrated examples. 1 is a base material made of a weather-resistant, almost square steel plate that can be press-formed and has undergone oxidation-promoting stabilization treatment.
The base material 1 has stepped portions 2 and 3 that are bent high toward the rear at required intervals determined as the length of the roofing foot, so that the exposed portion 4 and the non-exposed portion 5 are approximately equal in length, and the non-exposed portion has the same length. 5 and a non-exposed rear part 6 which is significantly shorter than 5.

In each of the above parts, a plurality of comparatively wide ribs 7, 7 are formed in parallel with each other, crossing each step part 2, 3 at right angles and convex on the front side with a trapezoidal cross section, and their positions are in the width direction. It is set up approximately 1/4 width apart from the center line. Also, around the base material 1, there is a tip side piece 8, front side pieces 9, 9, rear side side 10, and rear side pieces 1.
2 and 12 are bent. Among these side pieces, the tip side piece 8 and the front side pieces 9, 9 on the three sides of the exposed part 4 of the base material 1 are bent to the back side and face downward, forming a water return. The rear end side piece 10 of the non-exposed part 6 and the rear side pieces 12, 12 on both sides of the non-exposed part 5 and the overlapped part 6 are bent to the front side and are oriented upward.

Reference numeral 13 denotes a rain cover protrusion, which is protruded from the widthwise center of the rear part 6 of the non-exposed part, extending over the stepped part 3 at the border with the non-exposed part 5.

Next, we will talk about the tiling of the roof tiles of the above structure. First, as shown in Figures 5 and 6, the main building 1
Asphalt roofing 15 is laid on the roofing board 14 constructed on top of 8. Next, the roof tiles 11 of row A of the eaves are laid on the asphalt roofing 15 and fixed to the roof base using nail holes provided in the ribs 7. At this time, a roofing stopper 16 is placed on the lower side of each of the ends 2 and 3, which also serves as a tile beam.
Once row A of the eaves is completed, lay out the second row B. Each roof tile 11 spans two tiles in row A,
Also, if the exposed part 4 is shifted so that it overlaps the non-exposed part 5 in row A and the roofing is added, the upper and lower roof tiles 1
The ribs 7, 7 of No. 1 overlap each other alternately on the left and right in the correct position. When the stacking is completed, caulking is applied to the inside of the tip side piece 8 and the joints, and the third row C is tiled. Further, the roof tiles 11 in each row are fixed with nails 17 at the rib 7 portions, as shown in FIGS. 7 and 8.

Incidentally, since the rain cover protrusion 13 can be used as a seat for a fixing nail, the fixing of the tile 11 is not limited to the above embodiment.

As mentioned above, this idea consists of bending the base material 1 made of a substantially square steel plate high backwards at predetermined intervals determined as the length of the roofing foot, and creating an exposed part 4 of approximately equal length and an unexposed part 4 of the stepped part. 5 and a non-exposed part rear part 6 whose length is significantly shorter than the non-exposed part 5, and the three side pieces 8, 9,
9 on the back side, and the non-exposed part 5 and the non-exposed part rear part 6
The side pieces 12, 12 of the tile and the rear end side piece 10 of the rear part 6 of the non-exposed part are bent to the front side to form downward and upward side pieces around the base material, so that when the tile is wiped, the non-exposed part Since the tiles are triple-layered at the rear part 6, the roof tiles are thicker and look better than when the steel plates are simply laid one on top of the other.

In addition, ribs are provided to prevent warping, and the side pieces around the base material are turned downward in exposed areas.
The area behind the non-exposed area was formed upward, and the upper area was in contact with the upper tile, so the area around each tile on the roof was closed off as shown in Figure 8, and wind blowing was extremely prevented. Even if there is a space in the overlapped part, it does not become a wind channel, and it can withstand strong winds. Furthermore, by introducing an appropriate amount of bulge into each tile during pressing, the tip of the tile will be tighter after nailing, and it will be possible to prevent light from wind and rain. In addition, the upward facing side pieces prevent water from accumulating due to surface tension, and since there are no capillary gaps as a whole except for the overlapping portions of the ribs, water can be drained easily.

In addition, a rain protection protrusion 13 is provided at the center of the rear part 6 of the non-exposed part and extends to the border with the non-exposed part 5, in order to prevent water from entering from the seam of the exposed part 4 of the upper tile.
Even if rainwater blows up on the tile surface and enters the joint with force, the rainwater can be distributed to the left and right to reduce the force, and even in strong winds and rain, the rainwater will not leak over the rear edge. do not have. Moreover, since the entire tile can be manufactured in one press process, it is suitable for mass production, and has features such as being easy to install, requiring no special techniques, and not being restricted by the slope of the roof.
