Abstract

PROBLEM TO BE SOLVED: To facilitate roof panel positioning and improve execution accuracy in laying a roof panel by forming a step portion for locking on the rear surface of a roof panel, and fixing a batten for locking to the cross beam of a main house beam or the like. SOLUTION: A rectangular cross-sectional batten 1c is fixed to the rear surface of a roof panel 1 having a surface material being laminated integrally to a core material 1b so as to form a joint-step portion 1d. Then, a rectangular cross-sectional batten 2b is secured on the upper surface of a beam material 2 such as a main house beam and eaves by forming a slant surface 2a equal to an inclination of the roof, or a triangle batten 2b is secured by making the upper surface of the beam material 2 horizontal, and positioning is executed by locking the joint-step portion 1d of the roof panel 1 to the batten 2b, and then the roof panel 1 is fixed to the beam material 2 by nailing, screwing, and the like, thereby completing under roofing material. Besides, it is preferable that a part of the surface material 1a is cut off so as to be a joint-step portion 1d without fixing the cross-sectional batten 1c to the roof panel 1. This allows the roof panel 1 to be positioned readily, and thus its execution accuracy can be improved.
