- - Press-in nut-bolt assembly and construction method of steel material-concrete complex structure using it

摘要

The present invention relates to an assembly of a press-fit nut and a stud bolt that are previously installed in a press-fitting method on a base material. The press-fit nut includes a head portion and a press-fit portion protruding from one of the two sides of the head portion with a reduced diameter and inserted into the base material by press-fitting, and a thread on the inner surface of the head portion and the press-fit portion One formed hollow is continuously formed. The stud bolt is formed in a shape that is coupled in a form penetrating through the press-fit nut, a first threaded portion and a second threaded portion formed to be spaced apart from each other on the outer surface of the body portion, and a shape extending in the longitudinal direction to the end of the body portion And a pin tail for rotating the body portion.
