A modular combined-type wall-attached support rod of a tower crane relates to the technical field of structures of accessories of cranes and comprises a lug fixing rod and a fine adjustment rod, which are coaxially arranged, wherein one end of the lug fixing rod is fixedly connected with a first ear plate; the fine adjustment rod comprises a short rod, a second ear plate, a connecting screw rod, a first nut and a second nut; and pin holes on the short rod and the lug fixing rod are used for being connected with detachable joints through connecting pins. According to the modular combined-type wall-attached support rod, the fine adjustment rod can be directly connected with the lug fixing rod through the detachable joints, and middle extension rods with different lengths can be connected and replaced between the fine adjustment rod and the lug fixing rod so as to reach any length and realize the adjustment of the large-size wall-attached support rod. Owing to the connection relation between the screw rod and the first and second nuts, the fine adjustment of the length of the wall-attached support rod can be realized. Therefore, the modular combined-type wall-attached support rod adapts and meets use demands.
