Building has light roof extending either side ridgepole line with rigid shield above rooftop connected by point connections

摘要

Building roof (11) has two sides extending either side ridgepole line (9) to form dihedral shaped rooftop. Rigid shield (13) is located above rooftop and connected to roof by point connection parts (14,15). Edges of dihedral shaped shield extend in same vertical plane as ridgepole line. Upper dihedral has two surfaces (16,17) of pitch length adapted so that lower generating line of surfaces extends in horizontal plane secant with rooftop.
