The invention discloses an assembly type bolted connection reinforced wood constraint buckling-restrained brace, comprising an inner core, a peripheral constraint part, a steel filler strip and a filling steel plate; the peripheral constraint part is formed by upper laminated wood and lower laminated wood which are connected by bolts, bolt holes are formed in the laminated wood, the steel filter strip is arranged between the upper and lower laminated wood, and the upper and lower laminated wood are connected into a whole by gluing pressurization; the buckling section and the transition section of the inner core are arranged in the peripheral constraint part, the filling steel plate is arranged between the buckling section of the inner core and the laminated wood of the peripheral constraint part, preformed holes are formed in the filling steel plate, a tiny gas is reserved between the buckling section of the inner core and the filling steel plate, and the filling steel plate is connected with the laminated wood of the peripheral constraint part by gluing pressurization. The brace can improve the ductility and the energy dissipating capacity of the support structure of a wood frame, and assembly type production can be carried out on the brace in a factory, so that field construction work load can be reduced, construction progress can be promoted, connection quality can be ensured, and structure installation is facilitated.
