PROBLEM TO BE SOLVED: To provide a traveling construction method capable of lowering a cost and holding a sliding rail upper face and a shoe parallel to each other for normal traveling in spite of deformation of a frame unit. SOLUTION: In this traveling construction method, the frame units 1 each assembled in a fixed position are sequentially slid on a rail 2 so as to be connected together for constructing a large frame. In the lower ends in both of left and right column pedestal parts in the frame unit 1, shoes 9 brought into contact oppose to the rail 2 upper face are installed via a pin mechanism 7 for a rotary shaft core P2 parallel to the longitudinal direction of the rail 2. In this way, the rail 2 upper face and the shoe 9 are held parallel to each other in spite of deformation in the frame unit 1 caused by the dead-weight.
