The present invention relates to a two-segment PC wind flow slab structure enhancing constructability by a hinge structure using a T-type bolt and a construction method using the same and, more specifically, to a noble two-segment PC wind flow slab structure enhancing constructability by a new hinge structure using a T-type bolt, the two-segment PC wind flow slab structure being easy to construct and preventing damage of adjacent ends caused by a collision of wind flow slabs to enhance durability, and a construction method using the same. The present invention may provide a two-segment PC wind flow slab structure with a noble structure enhancing constructability by a hinge structure using a T-type bolt and a construction method using the same, wherein the two-segment PC wind flow slab structure has a simple structure, as compared with a conventional wind flow construction structure of fixating left and right side window flow slabs by a partition, to be easy to construct with enhanced durability and can prevent occurrence of a shock or damage of adjacent ends of wind flow slabs caused by a mutual collision of the wind flow slabs. The two-segment PC wind flow slab structure comprises: a support block provided on an upper surface of a wind flow bracket to come into close contact with an inner circumferential surface of a tunnel and supporting external ends of left and right wind flow slabs; a shock absorbing plate provided on the upper surface of the wind flow bracket and supporting lower side surfaces of external ends of the left and right side wind flow slabs; a support pin provided on the upper surface of the wind flow bracket to penetrate the shock absorbing plate and to protrude upwards; and a fixation tube body coupled to an external side of an upper end of the support pin to make a lower end come into close contact with an upper surface of the shock absorbing plate and filled with an asphalt filler. 본 발명은 T형볼트를 이용한 힌지 구조로 시공성을 개선한 2분절 PC풍도슬래브 구조물 및 이를 이용한 시공방법에 관한 것으로서, 더욱 상세하게는 더욱 상세하게는 시공이 용이하면서 풍도슬래브가 충돌에 의해 인접단이 손상되는 것을 방지하여 내구성이 향상된 새로운 T형볼트를 이용한 힌지 구조로 시공성을 개선한 2분절 PC풍도슬래브 구조물 및 이를 이용한 시공방법에 관한 것이다. 상기한 바에 따르면, 좌우측의 풍도슬래브가 격벽에 의해 고정되는 종래의 풍도 시공구조에 비해 구조가 간단하여, 시공이 용이하면서 내구성이 향상된 새로운 구조의 T형볼트를 이용한 힌지 구조로 시공성을 개선한 2분절 PC풍도슬래브 구조물 및 이를 이용한 시공방법을 제공할 수 있으며, 풍도슬래브가 상호 충돌하여 충격이 발생되거나, 풍도슬래브의 인접단이 손상되는 것을 방지할 수 있는 새로운 구조의 T형볼트를 이용한 힌지 구조로 시공성을 개선한 2분절 PC풍도슬래브 구조물 및 이를 이용한 시공방법을 제공할 수 있다.
