ことを防止できる。As described above, in the lath structure and the lath stopper construction method according to the present invention, the lath is formed in advance to a size corresponding to the wall thickness, and the reinforcing material is attached to the net surface. In addition, there is no need to process the lath on-site, and high-precision construction can be performed without causing variations in quality due to the skill of the operator. Further, welding work on site is not required, and the formwork can be prevented from being burned out by welding sparks or the like at the time of on-site processing.
