Description

The stud bolt and the joint structure of the filling pipe column and the beam member {STUD BOLT AND CONNECTING STURCTURE BETWEEN COLUMN AND BEAM}

The present invention relates to a stud bolt and a joint structure of a filling pipe column and a beam member.

It should be noted that the content described in this section merely provides background information on the present invention and does not constitute the prior art.

CFT column refers to a concrete filled steel pipe in which concrete is filled in a round or square steel pipe.

CFT columns exhibit excellent performance in various fields such as fire resistance and construction, as well as structural aspects such as rigidity, proof strength, and deformation because the steel pipe restrains the concrete.

Outer diaphragm, inner diaphragm, and penetrating diaphragm are used to connect the CFT column that pours concrete inside the steel pipe, which is widely used in buildings, and the steel frame interpolation.

However, since the joining process between the CFT column and the steel frame interpolation is made by welding, it requires a lot of manufacturing cost and work time, and skillful work skills are required.

Therefore, a bonding technique that even beginners can work with while maintaining high quality is required.

In addition, a separate operation of attaching studs or plates to the inside of the steel pipe is required for an integrated behavior between the steel pipe and the internal concrete.
