A prefabricated structure is provided to form external appearance variously by installing a structure such as a roof at various angles and to promote the convenience of installation by connecting frames simply without cutting off frames. Disclosed is the prefabricated structure(1), which comprises frames(2) installed vertically or horizontally, and a connecting unit(10) connecting the frames. The connecting unit comprises a pair of fixing rings connected with each other by two connecting pieces having different height and pressurized by bolts to form a coupling space, an angle regulating member inserted to the inside of the fixing rings and provided with a fitting hole corresponding to the coupling space, a primary connecting member formed in a rectangle and fixed to the fitting hole of the angle regulating member by bolts, a secondary connecting member formed in a cylinder and provided with a frame fixing plate fixed to the fixing rings laterally by bolts, and frame fixing plates adhered closely to the primary connecting member and the connecting piece projected downward and fixed with bolts.
