The present invention relates to a rahmen structure and a construction method thereof, wherein the rahmen structure comprises: multiple walls (400) installed at intervals; an arch part (100) having both end parts combined with the upper parts of the multiple walls (400) respectively and forming an arciform structure; an upper plate part (200) formed by pouring concrete above the arch part (100) and the walls (400); and a hollow part (300) formed at both end parts of a region between the arch part (100) and the upper plate part (200). Rapid construction is enabled to improve constructability and economical efficiency as structural hardness is enhanced and a shore is not necessary. The present invention can be applied easily to the construction of a long-span bridge by reducing a flexural moment via the stepwise construction of forming a slab and concave corners after the formation of the walls. |
