摘要
The present invention relates to a fit-together type of precast concrete lining and bridging structural body in which main girders are integrated with deck plates. Precast concrete deck members connected in longitudinal and transverse directions are pre-stressed by pre-stressed members, thereby making it possible to increase load carrying capacity or rigidity of a structure to stably use the structure for a long time. Further, it is possible to support the load applied from the top of a deck structure with a small thickness, and to make the deck structure light. Due to a knockdown type (fit-together type), installation and dismantlement are easy, and reuse is possible, and thus it is possible to provide convenient construction and low production costs.
