することにより継手部分を補強していたが。PRIOR ART In the past, underground continuous walls have been constructed using various methods, but in most cases, reinforcing bars are built in a trench that is excavated to a predetermined depth, continuing as appropriate in the width direction. This is a method of creating concrete by pouring concrete into the concrete, but in underground continuous walls constructed using this type of construction method, adjacent reinforcing bars and transverse bars are connected continuously so that the stress within the reinforcing bars can be transmitted smoothly. Because it was a national crisis to do so, the joints between the reinforcing bars were the weakest point in terms of strength. For this reason, the joints are reinforced by attaching reinforcing reinforcing bars to the joints between horizontal bars and adjacent reinforcing bars, or by connecting the horizontal bars with joint hardware made of steel, etc. but.

In addition, with conventional joint hardware of this kind, it is extremely difficult to connect horizontal reinforcing bars at the corners of the reinforcing bars so that stress within the reinforcing bars can be transmitted continuously, and to fix them in a predetermined position after being installed in a trench. there were.
