Description of the Related Art In the prior art, when joining a wall, a carpenter first assembles a wall formwork on one side, and then a reinforcing bar assembles wall reinforcing bars to arrange the bars. Then, according to the dimension between the rebars, the blacksmith processes lath steel or steel material with gas cutting, scissors, etc. into a lath net for concrete splicing and stretches it between the splicing parts of the wall. Paste the lath. Further, the carpenter assembles the other return wall formwork, casts concrete, and after the concrete hardens, the formwork is removed from the formwork. Finally, the scavenger spilled concrete spills, etc. that occurred between the wall formwork and the lath, and then the joint joint,
A common construction method is to repair the wood cone treatment with mortar or the like.

A lath pre-manufactured in a factory or the like having dimensions according to the wall thickness is brought into the field, and after the carpenter assembles the wall formwork on one side, it can be easily placed at a predetermined position Can be attached to. Further, since the wall reinforcing bars can be arranged only by penetrating the mesh surface of the lath, blacksmithing is not required, and the formwork reinforcing bar work can be continuously performed. Further, since the lath is factory-processed, the precision of the wall splicing portion is improved, concrete leaks are eliminated, and scavenging work is also unnecessary.
