In a snap-in structure of aluminum alloy roof, roof panel, and corner-connecting materials, a roof panel's splicing base is connected with a splicing depression bar and secured by screws. Meanwhile, its bulge is connected with a snap-in groove, and its clasp is hooked with the clasp on the support section. A roof's splicing base is connected with a splicing depression bar and secured by screws. At the same time, its bulge is connected with a snap-in groove. The first corner-connecting material has an acute angle shape. Its transverse splicing base is engaged with the roof panel's splicing depression bar, and its longitudinal splicing base is engaged with the roof's splicing depression bar. The second corner-connecting material's splicing depression bar is attached with a roof panel's splicing base. A combination of the insert spell buckle and screws fixes without using any sealing materials. It is waterproof and easy to install. It is primarily applied to install at an aluminum alloy house's wall and roof.

Prefabricated wall assemblies for the construction of buildings have a corrugated panel and preferably include at least one backside panel. The corrugated panel has one or more vertical channels and several horizontal channels. The vertical channels extend the entire panel height and are recessed from the front face. The horizontal channels extending the entire panel width and are also recessed from the front face so they intersect with the vertical channel. The horizontal channels are almost as wide as the vertical channels, and are greater than one-half the vertical channel width. The backside panel is connected to the corrugated panel to form a structural panel assembly. The backside panel can be a shear panel or other backside flat panel, a backside corrugated panel symmetrically mirroring the corrugated panel, a backside corrugated panel asymmetrically mirroring the corrugated panel, a sandwiched corrugated panel, a relief panel or any combination thereof.
