DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a repair metal sheet roof material which is used by directly attaching to a slate roof.

[0002]

2. Description of the Related Art Conventionally, a metal sheet roof capable of repairing a slate roof by attaching a new repair metal sheet roof material directly to an existing slate roof without breaking down an old slate roof. Lumber was present. Even in the case of a conventional metal sheet roofing material for repairing a slate roof, as shown in FIG.
An inclined surface mounting portion 4 is provided on both left and right sides of a mountain portion 3 of a metal sheet roofing material 2 for repair, and a load is widely dispersed by making a surface contact of the inclined surface mounting portion 4 with an existing slate roof 1. (Japanese Utility Model Publication No. 63-46576).

[0003] Originally, a slate roof has a fixed distance from one mountain to the next (a single dimension from one mountain to the next is formed as a reliable dimension of 130 mm).
The slate overlap line for continuous roofing must also be straight. However, since the slate material is a short-length processed product (6, 7, or 8), the slate has a finish that is not necessarily roofed straight. In addition, since the conventional metal sheet roofing material 2 for repair is formed by processing thin sheet materials having various sheet thicknesses, there is a slight change between the processing from each mountain to the mountain. It may not be possible to provide a stable roofing method. The conventional metal sheet roofing material 2 for repair has not solved this point, and thus the pitch of the metal sheet roofing material 2 for repair as shown in FIG.

[0004]

SUMMARY OF THE INVENTION The present invention relates to a metal sheet roofing material for repairing a slate roof, which is provided with a bounce provided between a round portion immediately before a slope mounting portion and a slope mounting portion and a valley portion. The pitch width of the repair metal sheet roof material can be easily adjusted even if the existing line of the slate roof is bent or misaligned due to the An object of the present invention is to provide a repair metal sheet roofing material.

[0005]

In order to solve the above problems, a ridge and a valley are formed continuously according to the pitch of an existing slate roof, and the height of the ridge is adjusted to the height of the existing slate roof. A space is created between the new mountain and the existing mountain when it is placed on thatched roof, and the surface is placed on both sides of the existing slate roof on both sides of the mountain in face contact. In a metal sheet roofing material for repairing a slate roof in which a slope mounting portion to be formed is formed, a radius is provided at a portion transitioning from a mountain portion to a slope mounting portion, and a valley portion is formed from the slope mounting portion. towards somewhat to provide a repairing metal sheet roofing slate葺roof, characterized in that a jump portion has an angle upward.

[0006]

Embodiments of the present invention will be described below with reference to the illustrated embodiments. FIG. 1 is a front view of a metal sheet roof material for repairing a slate roof according to the present invention, and FIG.
It is a partial enlarged view. The metal sheet roofing material 2 for repairing the slate roof in FIG. 1 is formed by bending a thin steel plate, and the ridge 3 and the valley 5 corresponding to the pitch of the existing slate roof 1 are formed. It is formed continuously.

As shown in FIG. 2, the height of the mountain 3 is such that a space is created between the new mountain 3 and the existing mountain when it is mounted on the existing slate roof 1. ing. A fixture such as an existing bolt (not shown) is accommodated in the space.

The top 6 of the mountain 3 is shaped like a mountain cap with a sharp peak. As a result, rainwater is prevented from accumulating in the top part 6 of the newly-installed metal sheet roofing material 2 for repair.

In this embodiment, the width from the peak 3 to the valley 5
That is, the depth of the valley 3 is set to be deeper than the conventional metal sheet roofing material 2 for repair. The depth of the valley portion 5 of the conventional repair metal sheet roofing material 2 is about 30 mm, but is set to about 45 mm in the present embodiment.
For this reason, the conventional metal sheet roofing material 2 for repair uses a thin steel plate having a width of 914 mm, and the six ridges 3 are formed by bending. However, in this embodiment, a thin steel plate having a width of 762 mm is used. The number of the peaks 3 including the overlapping portions is five using the above.
By using the thin steel sheet having the above width, the metal sheet roofing material 2 for repair can be reduced in weight, and the transportation work is facilitated. In particular, the construction of a sloping high roof helped to ensure safety.

As shown in the end portion of FIG. 1, an overlapping ridge portion (a ridge portion located below when overlapping) at one end portion of the repair metal sheet roofing material 2 of the present embodiment includes: A rainwater intrusion prevention step 11 is provided. Therefore, when the repair metal sheet roofing materials 2 are superimposed on each other, as shown in FIG.
A space is formed in the rainwater intrusion prevention step portion 11, and it is possible to prevent rainwater from intruding into the inside due to a capillary phenomenon.

The mountain portion 3 forms side portions 7 on both side ends of the mountain-shape top portion 6 obliquely outward from the vertical. The side portion 7 has an inclined surface mounting portion 4, a jumping portion 9 and a mountain portion 3.
A curved portion 8 is formed at a portion where the transition to the inclined surface placing portion 4 is made. The raised portion 9 is formed at an angle slightly upward so as not to normally contact the slate roof 1 when the repair metal plate roofing material 2 is installed. By forming a gap between the roofing materials 2, the existing slate roof 1 is formed so as to be able to adjust for the displacement caused by the bending.

The valley portion 5 extends slightly below the lower ends of the left and right jump portions 9. Near the middle of the valley 5, a V-shaped bent line rib 10 is provided. still,
The valley 5 is inclined downward toward the fold line rib 10 near the middle.

[0013]

The present invention has the following effects because it is configured as described above. Firstly, in the present invention, since a portion of the metal sheet for repair roof material that transitions from the peak to the inclined surface mounting portion is a round portion, pressure is applied to the peak to widen the peak, and thereby the metal sheet for repair is repaired. In the case of a gap that allows the pitch width of the roofing material to be adjusted, the radius can easily slide down at the point of contact with the slate roof, and the pitch width of the repair metal sheet roofing material can be easily adjusted. It became.

Secondly, since a jumping portion is provided from the inclined surface mounting portion toward the valley, a gap is formed between the left and right sides of the existing slate roof and the jumping portion. It is now possible to adjust for the displacement caused by the curved roof.

Thirdly, according to the second aspect of the present invention, in the case where the pitch of the repair metal sheet roof material is displaced to such an extent that the pitch width can be adjusted, the radius of the repair metal sheet roof material slides down. Further, the inclined surface mounting portion and the jumping portion are shifted downward. Since the valley of the slate roof is narrower as it goes downward, a folding line rib is provided near the middle of the valley,
Since the valley is inclined downward toward the fold line rib near the middle of the valley, the valley can be easily bent deep downward, and it can escape from the displacement caused by the bending of the existing slate roof. became.

Fourthly, the effect of the embodiment is that the existing slate roof is covered with the new slate roof by making the depth of the valley deeper than the conventional depth. The stability of the mountains has been improved.
