The invention provides a novel overlapping structure of a frame plate and a section material. Angle boxes are added at overlapping positions of the section material and the frame plate, and reinforcing plates are added at angle box positions, so that the overloading of the overlapping positions is transmitted; besides washer structures are added in bolt tightening regions, so that extruding pressure from bolts on the section material is reduced.
