[0003] This conventional roofing structure has a sheet covering the entire surface of the roofing material, including a portion that does not require repairing, for a wide range of repairing such as a case where there are many places where the roofing material is damaged by rain leaks, rust, etc. Is attached. However, if unevenness is formed on the outer surface of the roofing material, such as Kawara sticks, corrugated sheet slats, folded board roofs and goby folded board roofs, it is difficult to attach the sheet to the entire surface of the roofing material. Therefore, the entire roofing work will be carried out, in which the damaged roofing material is completely removed and a new roofing material is entirely roofed.

[0004] The conventional roofing structure that involves the entire roofing work for roofing has a problem that the construction period is long and the construction cost is high. Furthermore, there is a problem that it is difficult to ensure the safety of construction work due to the construction scaffolding. Further, there is a problem that the building cannot be used during the construction period due to the danger of falling objects due to the construction.

[0005]

[Problems to be solved by the device]

 The present invention has been made in consideration of the above-mentioned problems, and it is possible to repair a wide range of roofing materials having irregularities on the outer surface within a short period while continuing to use the building to be repaired. It is an object to provide a roof repair structure that can be safely constructed at low construction cost.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the roof repair structure according to the present invention is a roofing structure in which irregularities are formed on the outer surface of a roofing roof material, and a square corrugated sheet is used as a base material on the entire surface of the roofing material. It is fixed, and a sheet having at least waterproof property is stretched in a flat plate shape along the convex portion on the base material.

[0007]

[Action]

 According to the above-mentioned means, the damaged roofing material is covered with the new roofing material consisting of the base material and the sheet. Therefore, the damaged roofing material is not removed but secured as a construction scaffolding and also as a shielding material against fallen objects. It is functional and eliminates the cost of removing damaged roofing material. Furthermore, as the base material, use square corrugated sheets and other molding materials that are distributed in large quantities as ready-made products, and use sheets that are widely distributed as ready-made products instead of special sheets. Therefore, the material cost of the new roofing material will be low.

Therefore, for repairing a wide range of roofing material having an uneven surface on its outer surface, it is possible to safely perform construction at a low construction cost within a short period while continuing to use the building to be repaired. The problem of providing a roof repair structure is solved.

As for the roof material 10 of such a Kawara bar roof, a base material 1 made of an off-the-shelf corrugated sheet having a concavo-convex structure in which square concave portions 11 and convex portions 12 are continuously formed on the entire outer surface 1 Is fixed. The base material 1 looks like the recess 11 is hung on the roof rod 10b of the roof material 10, and the concave-convex structure composed of the recess 11 and the projection 12 is the roof material including the flat surface portion 10a and the roof rod 10b. It is arranged so as to be orthogonal to the 10 uneven portions. The base material 1 is indirectly fixed to the roof material 10 via an auxiliary material 2 interposed between the recess 11 and the flat surface portion 10a of the roof material 10. The auxiliary member 2 has a U-shaped cross section, and the open lower end of the U-shaped member is bent into an L-shape and abuts against the flat surface portion 10a of the roof member 10 and is fixed by a screw 3 to form a U-shape. The concave portion 11 of the base material 1 is brought into contact with the closed upper end and fixed with the screw 4.

On the base material 1 fixed on the entire outer surface of the roof material 10 in this way, a sheet 5 made of a synthetic resin material having at least waterproof property or the like, which is easily available as an off-the-shelf product, is provided. It is stretched. The sheet 5 is stretched in a flat plate shape so as to cover the concave portions 11 along the convex portions 12 of the base material 1. In such tensioning of the sheet 5, means such as heat welding can be used in addition to the adhesion by the adhesive. The sheet 5 preferably has heat resistance, heat resistance, cold resistance, etc. in addition to water resistance.

When the sheet 5 is stretched on the base material 1, a corner member 6 having a U-shape, an L-shape or the like is provided on the lower surface and the side surface of the roof material 10 such as the eaves and the upper surface of the base material 1. It is effective to prevent rainwater from blowing in if it is fixed so that it fits and abuts. In addition, if a caulking material is applied between the corner member 6 and the roof material 10, the base material 1, and the sheet 5, the prevention of rainwater injection is further effective.

According to such an embodiment, since the base material 1 is fixed to the roof material 10 and the sheet 5 is stretched on the base material 1 without removing the damaged roof material 10, the roof material is Since 10 can be used as it is as a scaffolding for construction, construction can be carried out safely, and it is possible to prevent falling objects such as construction materials and tools from falling into the building. , You can continue to use the building during the construction period. Furthermore, the construction period and cost required for removing the damaged roofing material 10 are unnecessary, and the corrugated sheet and sheet 5 used as the base material 1 are ready-made and inexpensive, so the construction period is short and the material is short. Construction costs including costs can be reduced. Furthermore, since the corrugated sheet and sheet 5 used as the base material 1 are in large quantities in the market as ready-made products, they can be easily obtained, and repair materials for damage to the roofing material 10 are available. Repair work can be started immediately without the need for preparation.

Further, since the recessed portion 11 of the constructed base material 1 is supported by the roof rod 10b of the roof material 10 and the auxiliary material 2 in the direction in which the unevenness is orthogonal to each other, the base material 1 has considerable strength. There is. Further, since the screw 4 for fixing the base material 1 is used in the recess 11 thereof, it does not hinder the tensioning of the sheet 5.
