PROBLEM TO BE SOLVED: To provide an assembly method for segment inner setting reinforcement capable of having a good effect on labor saving and light workability by developing such a method that a curve is formed in a lateral side because there are so many problems to be improved in labor force and safety in the assembly method making the lattice-like reinforcement form the curve into an upward side in a process assembling the segment inner setting lattice-like reinforcement used for a tunnel or the like. SOLUTION: A rectangular frame (1) is perpendicularly held by a built-up holder column (6) in a detachable manner. A supporting arm (3) is horizontally fixed to the built-up holder column (6) in the vertical direction in multi-stage. When curved reinforcement (2), outside main reinforcement (4) and inside main reinforcement (4') are skiddingly inserted and mounted on supporting arm (3), and intersections of the curved reinforcement (2), the outside main reinforcement (4) and the inside main reinforcement (4') passing through the inside of the rectangular frame (1) to hold them in predetermined positions with the rectangular frame (1) are welded to assemble the lattice-like reinforcement.
