ROOFING PANEL AND FORMING METHOD THEREOF

PURPOSE:To facilitate execution of works as well as to improve the extent of watertightness by mounting a frame body on each plate roof member 1 parallelly installed in a roofing form and, after the clearance is subjected to caulking, charging and hardening synthetic resins for unification. CONSTITUTION:Each plate roof member 1 is parallelly installed on an installing block 2 tiltingly formed stepwise. Next, a frame body 3 partitioning a desired panel form is mounted on it, and a clearance between the frame body 3 and the plate roof member 1 is filled to by means of calking. The, an expandable synthetic resin 4' of urethane foam is charged up to every corner in the frame with an atomizer or spray gun or the like, leaving it intact under room temperature, and it is foamed and hardened, thereby a backing material 4. After hardening, the plate roof member 1 and the frame body 3 are firmly joined together for unification. With this constitution, nails and hook fittings all the disused for setting the frame body 3, thus any penetration of rainwater can be prevented from occurring without eatailing any clearance in a mutual lap part of the plate rool members 1.
