The present invention relates to composite shear-connection type precast concrete composite slab, using a horizontal shear connector of precast concrete (PC) composite slab and a shear cutter, and a construction method thereof. Three-dimensional shear connectors are embedded in both ends of the PC composite slab by being arranged on the vertical plane of a rib. Moreover, a shear cutter is formed on an upper surface of an upper plate between the three-dimensional shear connectors in the multiple longitudinal directions. Accordingly, The shear cutter and the three-dimensional shear connectors can resist against a horizontal shear force between the same and slab concrete. 프리캐스트 콘크리트(Precast Concrete: PC) 합성슬래브의 수평 전단연결재와 전단코터를 이용한 복합 전단연결 방식의 프리캐스트 콘크리트 합성슬래브 및 그 시공 방법에 관한 것으로서, 입체형 전단연결재는 프리캐스트 콘크리트 합성슬래브의 양 단부에 리브에 수직평면상으로 배근되어 매립되도록 형성되며, 상기 입체형 전단연결재 사이의 상부판 상면에는 전단커터가 다수 길이방향으로 형성되도록 하여, 상기 전단커터와 입체형 전단연결재가 슬래브 콘크리트와의 수평전단력에 함께 저항하도록 하게 된다.
