The present invention relates to a stud bolt assembly inserted into an anchor bolt on a concrete ceiling, to be used to hang an object. More specifically, the present invention relates to a stud bolt assembly disposed between a plurality of washers and nuts to support a steel structure at an upper end of a large washer while vertically moving along the longitudinal direction of an outer peripheral surface of a screw rod. According to the present invention, the stud bolt assembly includes a screw rod (100) having a male screw portion (102) along the longitudinal direction of an outer peripheral surface; a connection member (110) to which the screw rod (100) is coupled by a screw through one end portion; an anchor set including an anchor bolt (120) and an anchor cap (130) disposed from a lower portion of the anchor bolt (120) to surround an outer peripheral surface of the anchor bolt (120), and coupled to the other end portion of the connection member (110) by a screw; a large washer (140) and a small washer (150) sequentially inserted into the screw rod (100); a spring washer (160); and a nut (170). The stud bolt assembly further includes a vertically-moving washer disposed between the spring washer (160) and the nut (170) to vertically move along the longitudinal direction of the outer peripheral surface of the screw rod (100) to support a steel structure (8) at the upper end of the large washer (140). |
