In addition to being able to be rolled, the joint part can be double-wound or other means for reinforcement, which has the effect of easily imparting the desired strength to the joint part. Therefore, it is now possible to mechanically wind the hoop lines near the joint area, which previously had to be done by hand.
This has the effect of obtaining a highly reliable Shiguchi. In addition, most of the required strength of the shikiguchi can be set on the beam side, making it easier to erect columns and beams.
It also has the effect of improving work efficiency.
