PURPOSE: A two-segmented arch structure and a construction method thereof are provided to increase structural efficiency of a crown joint fixed connection, improve workability and construct the two-segmented arch structure at a low cost. CONSTITUTION: A 2-segmented arch structure comprises a segment body(10), a joint, a temporary support device(30), a reinforcing bar(40), and concrete. The segment body is manufactured in a two-segmented type by using a pre-casting method. The joint is formed on the ceiling portion, where a pair of the segment bodies is in contact with each other, in the segment body and includes a lower plate and a cutout portion. The temporary support device comprises a first member(31), a second member(32), a control device(33), and a rotation allowance member(60), and temporarily supports the pair of the segment bodies to maintain the contact with each other while an arch system is being constructed. The reinforcing bar is placed in the cutout portion. The concrete is poured in the cutout portion. |
