    • PROBLEM TO BE SOLVED: To provide the repair construction method for a batten-seam roof, by which the design of a batten seam and the shape of the batten seam in an existing batten-seam roof are held and the repairing work is simplified and which has a stable waterproofing function for a prolonged term, and its structure. SOLUTION: Both sides of waterproofing sheets A are bent and bottom plate sections 1 laid among adjacent batten-seam sections B and upstanding joining sections 2, 3 are formed previously on both sides of the bottom plate sections, each batten seam section is covered with approximately portal type resin-coated steel plates C and the steel plates are fixed, the upstanding joining sections 2 formed on one sides of the waterproofing sheets are joined with the resin-coated steel plates, the upstanding joining sections 3 formed on the other sides of adjacent other waterproofing sheets A in the batten seam sections are joined, the bottom plate sections of each waterproofing sheet are fixed onto a foundation E, upstanding joining sections are formed previously to the bottom plate sections and both sides of the bottom plate sections, the upstanding joining sections of the adjacent waterproofing sheets are abutted and joined on the top faces of the resin-coated steel plates, and band sheets D for joining are cemented with the top faces of the upstanding joining sections of the waterproofing sheets.

    • PROBLEM TO BE SOLVED: To obtain strong pull-out strength even to a metallic roof foundation having thin plate thickness by setting difference between the maximum outside diameter of the drill section of a drill screw and the height of the projecting section of thread cutting and the angle of the apex of a screw thread at specific values respectively. SOLUTION: The thread overlap (a) of the screw thread of a drill screw A consisting of an iron material, etc., to which corrosion-resistant treatment is executed. is set at a value from 1.0-2.0mm, and the angle α of the apex of the screw thread is formed in 30-50 deg.. Length is set in 20-200mm, a diameter in 4-10mm and the pitch interval of the screw thread in 1-2mm, and properly selected and used in response to a rood foundation. A heat-insulating material 4, an insulating sheet 5 and a waterproof sheet 6 are spread successively over a metallic folded-plate roof 3, and fixed onto the projecting section of the metallic folded-plate roof 3 by screwing the drill screws A through a disk plate 7. Lastly, a sheet 8 made of a synthetic resin is joined with the disk plate 7 and the waterproof sheet 6 by heat fusion or a solvent and the disk plate 7 and the waterproof sheet 6 are covered with the sheet 8. Accordingly, excellent fixing strength is acquired, and the drill screw is not loosened by the vibrations of an earthquake, a wind, etc.
