According to the present invention, a nut type anchor bolt includes: a tightening part having a spiral part on one end in a rod shape and having an opening member on an outer circumferential surface; a fastening part having a fastening hole therein so as to be spirally fastened to the spiral part of the tightening part; and an expanding part integrally formed on an end portion of the fastening part and provided to pressurize an inner circumferential surface of a hole formed on a fixed structure while being opened by the opening member when the tightening part is rotated. According to the present invention, the nut type anchor bolt can be solidly fixed into the hole by digging into an inner surface of the hole of the fixed structure while the expanding part is expanded by the fastening part (opening part) in a nut structure positioned in the hole of the fixed structure while spirally fastened to the tightening part by rotating the tightening part in a bolt structure.
개시된 본 발명에 따른 너트식 앙카볼트는, 봉 형상으로 일단에 나선부가 형성되며, 외주면에 벌림부재가 형성되는 조임부; 상기 조임부의 나선부에 나선 체결되도록 내부에 체결공이 형성되는 체결부; 및 상기 체결부의 단부에 일체 형성되어, 상기 조임부의 회전시 상기 벌림부재에 의해 벌어지면서 고정 구조물에 형성된 홀의 내주면을 가압하도록 구비된 확장부;를 포함한다. 본 발명에 의하면, 볼트 구조의 조임부를 회전시켜 조임부와 나선 체결되면서 고정 구조물의 홀 내에 위치된 너트 구조의 체결부(벌림부)에 의해 확장부가 확장되면서 고정 구조물의 홀 내면을 파고들어 홀 내에 견고하게 고정 가능한 효과가 있다.
