Zusammenfassung:	The present invention relates to a sleeve-expanding set anchor. More specifically, the present invention relates to a sleeve-expanding set anchor which is inserted into a mounting hole formed on a concrete structure to be firmly supported, thereby firmly installing and supporting a certain apparatus, structure, or the like. According to the present invention, in the sleeve-expanding set anchor including an anchor bolt, a sleeve, and a nut, the sleeve includes: a cylindrical main body surrounding the anchor bolt; a large number of penetrating holes formed by penetrating an outer circumferential surface of the cylindrical main body; an incision unit incising by crossing one end of the penetrating holes and the cylindrical main body on an outer circumferential surface of the cylindrical main body; a divided unfolding unit divided into a large number of parts from one end of the cylindrical main body by the incision unit; a large number of hanging bumps protruding from the divided unfolding unit toward an outer side; and a flow prevention bump protruding toward an inner circumferential surface of the cylindrical main body to come in contact with the screw thread, and prevent the cylindrical main body from shaking toward the anchor bolt. When the nut engaged with the screw thread rotates, the sleeve is pushed by the falling nut, and moves toward the head unit arranged on a lower side, and the divided unfolding unit opens by bending toward an outer side. 본 발명은 슬리브 확장형 세트앵커에 관한 것으로서, 특히 콘크리트 구조물에 형성된 장착홀에 삽입된 후 견고하게 지지되어, 소정의 장치, 구조물 등을 견고하게 설치하여 지지할 수 있는 슬리브 확장형 세트앵커에 관한 것이다. 본 발명의 슬리브 확장형 세트앵커는, 앵커볼트와 슬리브와 너트를 포함하여 이루어진 슬리브 확장형 세트앵커에 있어서, 상기 슬리브는, 상기 앵커볼트를 감싸는 원통본체와; 상기 원통본체의 외주면을 관통되어 형성된 다수개의 관통공과; 상기 원통본체의 외주면에서 상기 관통공과 상기 원통본체의 일단을 가로질러 절개하는 절개부와; 상기 절개부에 의해 상기 원통본체의 일단에서 다수개로 분할된 분할전개부와; 상기 분할전개부에서 외측방향으로 돌출형성된 다수개의 걸림돌기와; 상기 원통본체의 내주면 방향으로 돌출되어 상기 나사산에 접함으로서 상기 앵커볼트에 대한 상기 원통본체의 흔들림을 방지하는 유동방지돌기;를 포함하여 이루어지되, 상기 나사산에 결합된 상기 너트의 회전시 하강하는 상기 너트에 밀려 상기 슬리브는 하부에 배치되는 상기 헤드부 방향으로 이동하면서 상기 분할전개부가 외측방향으로 휘어지면서 벌어지는 것을 특징으로 한다.
