2. Description of the Related Art When a shingle roof becomes rusted, it is peeled off to expose a base material such as a lower beam or a girder, and a new foldable sheet may be replaced on the base material. However, this requires a lot of labor and cost for the work and disposal of waste, so the roof may be renovated by leaving the folded plate roof and laying a new folded plate on it. .

[0003] There are various methods for first laying a folded plate as a new construction. Usually, a tight frame bent in a zigzag shape in accordance with the folded plate is welded to a base material as a base, and furthermore, A method of placing a folded plate on a tight frame and tightening the folded plate on a tight frame with bolts, or a method of erecting a latch on the top of the tight frame and crimping the connecting pieces at both ends of the folded plate .

[0004] When a folded plate is laid using a latch as in the latter case, a new latch may be attached in the same manner as a renovation, and the folded plate may be newly laid on the old roof. At that time, special hardware was conventionally used for mounting the new latch and supporting the new folded plate, but the number of parts, especially bolts, is large, and the structure is very complicated and expensive. In addition, the work efficiency was poor because the installation was extremely troublesome.

[0005]

SUMMARY OF THE INVENTION In view of the above-mentioned circumstances, the present invention provides a roof having a simple structure, capable of strongly roofing a new folded plate, and having good workability. The purpose was to provide a renovation method.

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a conventional channel-shaped folded plate which is crimped into a corrugated step, and a crimped old connecting upright portion. In a renovated roof to which a new metal fitting is attached using the roof, a roof comprising a pair of left and right fastening plates which sits on the step top, sandwiches the old connecting upright portion, and extends above it. The roofing hardware is provided with a protruding part at the upper end of both or one of the fastening plates, and one of the fastening plates has a crimping projection of the old connection standing part at the lower end. A new hook is attached to the outside of one side of the fastening plate, and both the fastening plate and the new fastening bracket are attached to the upper side of the old connecting upright. The roof reform characterized by penetrating through and tightening with a nut It is intended to provide the law.

[0007] According to the above configuration, in order to roof a new folded plate,
The old roof is left as it is, and the old connection standing part at the top of the step has a caulking projection on one end at the upper end. Tighten the bolt with the hook of the plate hooked on the caulking projection. Therefore, a strong attachment state can be obtained, and the new latch can be firmly fixed at the same time by the tightening. In order to obtain this hooked state, it is no longer necessary to form a through hole for a bolt in the old connection standing part.

[0008] In addition, a cover is attached to both the fastening plates, and a fastening bolt is provided on one of the side surfaces.
When a new latch is applied to the outside of one surface and bolted, heat transfer between the old folded plate and the new folded plate can be shielded by the interposition of the cover.

Further, when a heat insulating material is filled between the new folded plate and the old folded plate, a roof structure having high heat insulating properties and soundproofing is obtained.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention is not limited to the embodiment described later. For example, in the embodiment described below, both the fastening plates 4 and 5 are independent pieces, As long as it can be held almost vertically, it can be configured as an integrated body that can be opened and closed at the upper end.

The cover 6 is desirably formed of a plastic material or an inorganic material having a lower thermal conductivity than metal and having high heat insulating performance. The cover 6 is formed separately from the fastening plates 4 and 5, but is formed by bonding or molding. It may be configured integrally by means.

The material of the heat insulating material 8 is not particularly limited. For example, a plastic heat insulating material and an inorganic fiber heat insulating material are used.

[0013]

As described above, according to the roof remodeling method of the present invention, the number of parts is small and the structure is simple, so that not only can it be provided at low cost, but also it is very simple to use. In addition, since it is not necessary to provide a through hole for a bolt in the old connection standing part, there is an excellent effect that the workability of the renovation is improved and that the new folded plate can be roofed firmly.

With the cover (Claim 2), the heat insulating property is improved, and when a heat insulating material is interposed between the old folded plate and the new folded plate (Claim 3), not only the heat insulating property is obtained. Sound insulation such as rain noise is improved.
