Abstract: A series of individual modular panels are combined to create a completed structure. Panels for floor, wall and roof are joined at common bearing points. The roof frame is a combination of pyramid and hip shaped units connected to create the structural framework for standard and multi-pitched pyramid and hip-type roofs. The structural framework acts as a single unit and creates both the exterior and interior shape in one assembly. The lower horizontal carriage of the roofs structural framework allows for easy installation of ceiling panels. The upper exterior diagonal and horizontal framework allows for easily installed weather tight roof panels. PV solar panels can be integrated into the roof panels, eliminating the need for additional racking. Lightweight tents as well as heavy commercial applications can benefit from this roof system. Electric supply lines are accommodated for with hollow channels integrated into the structural assembly.
