Furthermore, due to the large mass, the existing concrete roof board is difficult to be constructed, and its base bearing structure is also highly required. Besides, the existing concrete roof board has poor thermal insulation effect. Even if adding a thermal insulation layer structure, it is still hard to meet the thermal insulation requirement.
UK Patent Application Publication No. GB 2 391 026 A discloses a roofing system and roofing panel therefore and particularly discloses the following context. A prefabricated, modular roofing system includes main roof panels which can span the distance between gable ends and can be supported thereby and intermediate panels which do not span the whole roof and are supported by, and cooperate with, the main roof panels. One side of the roof system preferably includes at least two main roof panels, one set of intermediate panels arranged between the main roof panels to provide window openings, an eave panel and an apex panel. The cooperating surfaces may extend across the full length of the panels.
