Description

[Detailed Description of the Invention] The present invention relates to a metal roofing plate, and is particularly characterized in that the metal roofing plate is press-formed into the shape of a stone roofing.

In conventional metal sheet roofs, the surface of the metal sheet is not processed and is used in a flat state, so the roof is flat and lacks the three-dimensional feel of a tiled roof, making it difficult to design. There was a problem in that it had to be monotonous.

The purpose of this project is to provide a roofing sheet in which metal sheets are press-formed into the shape of a stone tiled roof, which is suitable for tiled roofs, especially Western-style houses. This is characterized in that by pressing the steps and creases that are created by the process, no distortion occurs on the surface of the stone plate-like part, which should be flat.

Next, to describe in detail an example in which the present invention is applied to the illustrated stone sheet roof, metal roof sheets 1 of a desired size cut into rectangles are press-formed into the same shape as the stone sheet roof. , the surface is baked in the same color as the stone slab and the background color, and the central part of the surface excluding the connecting overlapping pieces 2 and 3 on one end of the roof slab and one side along the longitudinal direction, along the longitudinal direction. In the stepped portion 4 representing the thickness (4 to 10 rran) of the stone slabs that overlap in the vertical direction, and in the upper and lower portions bordering on this stepped portion, lines 5 representing the connecting portions of horizontally adjacent stone slabs are formed, respectively. A large number of stone plate-like parts 6 are formed by pressing perpendicularly to the part 4.

When press forming each of the stone plate-like parts 6, a corrugated surface consisting of vertically striped shallow grooves 7 parallel to the grooves 5 and shallower than the depressions of the grooves is simultaneously pressed over the entire surface of the stone plate-like part 6. Molded.

Needless to say, the upper stone plate-like part 6 bordering on the step part 4
and the lower stone plate-like portions 6 are press-molded so that the positions of the lines 5 are shifted so that the respective stone plate-like portions are arranged in a staggered manner.

The connecting overlapping piece 2 provided at one end of the roof shingle 1 is inserted into the lower surface of the end of another adjacent roof shingle. The grooves 8 are provided in such a manner that the lower ends of the grooves are curved in the direction of the stone plate-shaped portion 6 on the lower side of the roof plate 1, and when rainwater flows to the overlapping part of the roof plates, the guide groove 8 allows the rainwater to be removed. The system actively flows down toward the bottom of the roof shingles to prevent it from falling onto the roofing boards on the back.

Further, on the upper edge of the roof plate 1, there is a connecting overlapping piece 3 for connecting with the upper roof plate 11, and on the lower edge, there is also a connecting piece 1 folded back in a U-shape toward the back side for connecting with the lower roof plate.
3 are respectively provided, and the connecting piece 13 is formed so as to fit into a connecting overlapping piece provided at the upper end of the lower roof panel.

The connecting overlapping piece 3 is formed by folding back in an S-shape toward the surface of the roof board to provide a connecting groove 14, and a deep groove 9 is recessed along the longitudinal direction of the piece.

This deep groove 9 is connected to another roof sheet 1 connected to the upper layer of the roof sheet 1.
It is constructed so that when rainwater flowing down from 1 flows in the direction of the connecting overlapping piece 3, it is stored and does not fall onto the roofing board.

The roof board according to the present invention has the above-mentioned structure, and when roofing is done, the roof board 1 is fixed by nailing the deep groove 9 in the connecting overlapping piece 3 to the rafters 10 that support the shedding board, as shown in Figure 4. Then, the connecting piece 13 at the lower end of the roof sheet 11 to be placed above the roof sheet 1 is fitted into the connecting groove 14 at the upper end of the fixed roof sheet 1, and is not connected to the side roof sheet 12. They are sequentially arranged by overlapping the edges using the overlapping pieces 2.

Incidentally, when nailing the deep groove 9, the nail holes are caulked to prevent water leakage from the nail holes.

As described above, the roof board according to the present invention is made by pressing the step part 4 representing the thickness of the stone boards that overlap in the vertical direction along the longitudinal direction of the board and the creases 5 representing the connection part of the horizontally adjacent stone boards. A roof board with a three-dimensional effect can be formed by forming a large number of continuous stone plate-like parts 6.

Furthermore, when pressing the stepped portions 4 and the creases 5 perpendicular thereto when forming a large number of slate-shaped portions 6, the surface of each slate-shaped portion 6 is pulled by the material for the surrounding stepped portions 4 and creases 5. Although distortion may occur and it may not be possible to maintain a completely flat surface, each stone p-shaped portion 6 is formed with a wavy surface consisting of vertical striped shallow grooves 7 parallel to the striations 5). Therefore, it is possible to reliably remove distortions in the plate surface of the stone plate-like portion 6 due to the pressing of the stepped portions 4 and the creases 5, and it is possible to realize an accurate stone plate shape.

Since the corrugated surface of this stone plate-like part 6 is formed from shallow grooves 7 which are shallower than the lines 5 that separate each stone plate-like part, when roofing is completed, the corrugated surface of the step part 4 and the lines 5 are separated. This wavy surface does not give an unusual impression as the shape of a stone slab, except that only the surface is visible.

Furthermore, the corrugated surface formed by the shallow grooves 7 in the stone plate-like portions 6 can provide strength over the entire surface of the roof plate, and these shallow grooves 7, together with the lines 5 separating each stone plate-like portion 6, strengthen the roof plate 1. give a constant downward direction to rainwater flowing down the surface).

Therefore, rainwater that flows down the surface of the roof shingle and falls from the bottom edge of the shingle to the connection area of the lower roof shingle will immediately penetrate into the lower roof shingle without stagnation laterally along the connection area of the lower shingle. (flowing downward along the corrugated surface of the roof), improving drainage and greatly reducing the rate of infiltration of rainwater into the periphery of the roof panels, making it possible to reliably prevent rain leaks even during rainstorms. By improving water drainage at the joints between the roof panels, corrosion can be prevented even during long-term use, and the service life can be expected to be extended.

In addition, the connecting overlapping piece 3 at the upper end of the roof plate of the present invention has a deep groove 9 recessed along the longitudinal direction of the piece.
Even if rainwater flowing down from another roof plate 11 connected to the upper layer of the roof plate 1 flows in the direction of the connecting overlapping piece 3, the deep groove 9
This has the effect of reliably preventing rainwater from seeping into the roof boards.
