| 摘要 |
A roof panel having at least one square shaped bottom structure, at least one lower lattice structure attached to the square shaped bottom structure, a plurality of connectors, each connector attaches to the square shaped bottom structure, an upper lattice structure, the upper lattice structure attaches to the square shaped bottom structure at a position above the lower lattice structure, a plurality of spacers, each spacer attaches and separates the upper lattice structure from the lower lattice structure, a U-shaped top structure, the U-shaped lop structure attaching to the square shaped bottom structure, an eaves skeleton, the eaves skeleton is attached to the side of the square shaped bottom structure adjacent to the open end of the U-shaped top structure, at least two beams, each beam housed within a space created after attaching each connector to each square shaped bottom structure, and a cement composite, the cement composite evenly covers the U-shaped top structure, the cement composite further covers the lower lattice structure, and the cement composite further covers the eaves.
