Description

[Detailed description of the invention] The present invention provides a hooking part that is folded back to the back side at the lower end of the metal roofing board 1, and a hooked part 2 that is folded back to the front side at the upper end of the metal roofing board 1. Engaging parts 4 folded back to the back side are provided on both sides of the roof plate 1, and engaged parts 6 folded back to the front side of both sides of a waste plate 5 placed below the abutting part between the horizontally adjacent metal roof plates 1 are provided. The attachment portions 5a of the sacrificial plates 5 that are engaged with the adjacent engagement portions 4 of the metal roof panels 1 and project upward from the upper end of the metal roof panels 1 are nailed to the roof base, and the coverings on both sides of the attachment portions 5a are nailed to the roof base. This relates to a metal roof formed by folding back a narrow piece 8 formed by making a cut 7 in an engaging part 6 from top to bottom and engaging it with a hook part 2 of a metal roof board 1.

The object of the present invention is to provide a metal roof that can reliably prevent horizontal and vertical movement of metal roof plates, prevent disconnection due to expansion and contraction, and has a good draining effect.

The present invention will be explained in detail below with reference to Examples.

Reference numeral 1 denotes a metal roofing plate made of metal such as copper or galvanized steel sheet, and the lower end of the metal roofing plate 1 is provided with a hook part 3 that is folded back to the back side, and the upper end of the metal roofing plate 1 is provided with a hook part 3. A hooked portion 2 is provided by folding back to the side, and engaging portions 4 are further provided by folding back to the back side on both sides of the metal roof plate 1.

A scrap board 5, which is longer than the length of the metal roof board 1 in the vertical direction, is provided with engagement parts 6 on both sides by being folded back toward the upper surface, and a hook part 3 is provided at the bottom of the scrap board 5 by being folded back toward the bottom surface. It is.

The upper part of the waste board 5 is a mounting part 5a.
In the engaged portions 6 on both sides, cuts 7 are made downward from the upper end to form narrow strips 8.

Further, if an ice cutting ridge 10 is provided in the vertical direction in the center of the waste plate 5 as shown in FIG. 5, the water cutting effect will be further improved.

When constructing a metal roof using the metal roofing sheets 1, a sacrificial sheet 5 is placed under the abutting part of the horizontally adjacent metal roofing sheets 1, and a nail is attached to the roof base at the attachment part 5a of the sacrificial sheet 5. Then, the engaging part 4 of the metal roofing board 1 is engaged with the engaged part 6 of the sacrificial board 5, and the narrow strip 8 is folded back and the narrow strip 8 is engaged with the hooked part 2.

The upper and lower metal roof panels 1 are connected by the upper metal roof panel 1.
The hooking portion 3 of the metal roof plate 1 is hooked onto the hooked portion 2 of the metal roof plate 1 located below to connect.

As described above, the present invention is provided with a hook part that is folded back to the back side at the lower end of the metal roof plate, and a hooked part that is folded back to the front side at the upper end of the metal roof plate, so that the metal roof plate located above can be By hooking the hook part onto the hooked part of the metal roof board located below, it is possible to connect the top and bottom of the metal roof board. The engaged parts folded back to the surface side on both sides of the waste board placed under the abutting parts between adjacent metal roofing boards are respectively engaged with the adjacent engaging parts of the metal roofing boards, and the upper end of the metal roofing board is Since the attachment part of the scrap board that protrudes further upwards is attached to the roof base, it is possible to install the metal roof plate so that it does not move from side to side. Since the thin strip formed by cutting a slit is folded back and attached to the hook part of the metal roofing board, the metal roofing board does not move up and down; Moreover, since the engaging part of the metal roofing board is connected by engaging the engaged part of the waste board, it is less likely to come off due to expansion and contraction compared to a system in which the metal roofing boards are directly engaged with each other. Furthermore, since there is a waste plate between the metal roof panels, it has a good draining effect.
