Document Type and Number:
WIPO Patent Application WO/2021/054744
Kind Code:
A1
Abstract:
The present invention relates to a press-fit nut for an assembly, a press-fit nut-bolt assembly, and a method of constructing a steel-concrete composite structure using same, wherein a process is simple and a base material does not become deformed during an installation process. The press-fit nut-bolt assembly of the present invention includes a press-fit nut, a stud bolt, a counter nut, and a washer. The press-fit nut includes: a head part formed in a typical nut shape; and a press-fitting part that is formed extending from one of the two surfaces of the head part so as to have an outer diameter less than that of the head part, and that is inserted, through press-fitting, into a base material (M) that is an object requiring fastening. A hollow having threads is continuously formed in the head part and the press-fitting part. The stud bolt includes a body part that is coupled to the press-fit nut by passing therethrough, and a pin tail which is formed extending from an end of the body part and to which a mechanism for rotating the body part is coupled. The body part includes a first threaded portion and a second threaded portion which are formed on the outer surface of the body part along the lengthwise direction of the body part and spaced apart from each other.
