PURPOSE:To efficiently execute the assembly work for a roof unit by forming the planary shape of four corner side roof units into square form, providing interchangeability, and forming the lower beam of other roof unit which contacts the above-described roof unit to the equal dimension. CONSTITUTION:A gambrel roof 10 is constituted of a cross-beam side roof unit 11, gable side roof unit 12, center part roof unit 14, and a corner side roof unit 15. In the corner side roof unit 15, a bundle 5B is installed at one corner part of the quadrangular lower beam 5A, and a corner beam 5C and rising beam 5D are installed between the corner parts, and a roof panel is installed. Further, also the lower beam 1A of a cross-beam side roof 11 which contacts the corner side roof unit 15 and the lower beam 2A of a gable side unit 12 are set to the equal dimension to the lower beam 5A. Accordingly, the corner side roof units 15 at four places can be used in common, and the assembly work can be executed with a high efficiency.
