<p>PURPOSE: To securely prevent even a large size panel from breaking at the middle thereof when being lifted and transferred and increase the mechanical strength. CONSTITUTION: A large size roof panel 10 is constituted of two unit panels 20 longitudinally connected to each other, panels 50 attached to the surface of the unified unit panels 20, and a roof finish material attached through the panels 50. In the connection of mutual unit panels 20, connection reinforcing plates 62 with the almost same height with the longitudinal core materials 30 are arranged in the clearance 60 between the side face of a plurality of longitudinal core materials 30 constituting the unit panel 20 and the end face of the shorter lateral core material 40 than the arranged distance of the longitudinal core materials 30 constituting the unit panels 20 likewise. The longitudinal core materials 30 of respective unit panels 20 and the connection reinforcing plates 62 are connected and fixed to each other.</p> |
