Problems solved by technology
[0008] Press-fit nuts have problems such as fast plastic deformation of the press-fit nut and brittle fracture of the base material due to the strong impact when it is press-fitted into the base material
Press-fit nuts are widely used because of their convenience and innovation, but because press-fit nuts have problems in the above-mentioned installation process and maintenance of firm installation, their technology still needs to be improved

Embodiment Construction
[0041] The present invention will be described in detail through the following description based on the accompanying drawings.
[0042] like figure 1 As shown, the fastening mechanism group according to the present embodiment is constituted by a press-fit nut 10 , a stud 20 , a countersunk nut 30 and a washer 40 .
[0043] like figure 1 and figure 2 As shown, the stud 20 is formed elongated and includes a body portion 21 that passes through the press-fit nut 10 to couple therewith, a first ridge 22 and a second ridge 23 that are formed along the length of the body portion 21 The directions are spaced apart from each other on the outer surface of the main body portion 21;
[0044] Examples of pin tails are Figure 4 to Figure 6 shown in.
[0045] like figure 1 As shown, the counter nut 30 has the same shape as a conventional nut and is provided on the opposite side of the press-fit nut 10, and the substrate M through which the stud bolt 20 passes is inserted between the ...

The invention relates to a press-fit nut for an assembly, a press-fit nut-bolt assembly and a method for constructing a steel-concrete composite structure by using the press-fit nut-bolt assembly, wherein the process is simple and a substrate does not deform during installation. A press-fit nut-bolt assembly of the present invention includes a press-fit nut, a stud, a countersunk nut, and a washer. The press-fit nut includes: a head formed in a typical nut shape; and a press-fit part which is formed so as to extend from one of the two surfaces of the head part so as to have a smaller outer diameter than the head part, and which is inserted by press-fit into a base material (M) that is an object to be fastened. A hollow portion having a screw thread is continuously formed in the head portion and the press-fit portion. The stud bolt includes: a main body portion coupled with the press-fit nut by passing through the press-fit nut; and a pin tail formed to extend from an end portion of the main body portion and coupled with a mechanism for rotating the main body portion. The main body portion includes a first threaded portion and a second threaded portion formed on an outer surface of the main body portion in a length direction of the main body portion and spaced apart from each other.
Description
technical field [0001] The present invention generally relates to a press-fit nut for an assembly, a press-fit nut-bolt assembly and a method of using the same to construct a steel-concrete composite structure, and more particularly to a press-fit nut, a press-fit nut for an assembly A nut-bolt assembly and method of using the same to construct a steel-concrete composite structure is simple to process and does not deform during the installation process on a substrate. Background technique [0002] Press-fit nuts are also known as so-called Pem nuts, lock nuts or one-way nuts. Use press-fit nuts when it is difficult to tighten the bolt and nut at the same time, or when the nut is difficult for a technician to access to tighten it. In particular, in the case where the plate-shaped member is the base material, it is necessary to attach bolts and nuts. At this point, only one side of the substrate is accessible, while the other side of the substrate is bonded or facing out of ...
