PURPOSE: To provide a roof panel structure which can bear against a large volume caused by a large snowfall, which can be curved up to a radius of curvature of about 30cm in the longitudinal direction of a panel and which is water-proof.
CONSTITUTION: A U-like roof panel unit 2 is provided at one side thereof with a horizontally extending overhang part 2 and a coupling part 3 which extends, being bent, from the overhang part 2, and is provided at the other end side with a horizontally extending overhang part 2 and a superposing coupling part 4 which extends, being bent, from the overhang part 2 and adapted to be superposed with the coupling part 3 of an adjacent roof panel unit 2. The coupling part 3 of the roof panel unit 1 is superposed with the coupling part 4 of the adjacent roof panel unit 2, and are fastened together so as to constitute a roof panel having large corrugation composed of curved surfaces having no angled parts.
