The utility model relates to the technical field of building structures, and particularly discloses a modularized wood structure roof which comprises a
butt joint frame which is of a frame structure connected with a house wall, first bearing strips are symmetrically installed at the upper end of the
butt joint frame, and the upper ends of the first bearing strips are in
butt joint with a roof frame; the roof house frame and the butt joint frame form a main frame structure of the wood structure roof. According to the modularized wood structure roof, the butt joint frame, the first bearing strip, the first connecting frame and the roof frame form a
solid foundation frame, meanwhile, the first bearing strip is spliced with the bottom end of the roof frame, and the first bearing strip and a groove in the upper end of a limiting strip enable the roof frame to be accurately clamped, so that the roof frame is prevented from being damaged. The heightening supporting
assembly is matched to provide extra supporting height and stability for the roof frame, all the components are manufactured in a standardized mode, rapid on-site construction and installation are facilitated, the on-site construction
workload and interference to the surrounding environment are reduced, meanwhile, the construction cost is reduced, and the construction efficiency and convenience are improved.
