から突出した釘をペンチ等で切取ったり、鎚で叩いて折
曲げている。Conventional construction inserts of this type include so-called nailed inserts with female screw bodies and iron nails, but when it comes to nail treatment after concrete pouring and curing, the nails protruding from the concrete surface must be cut with pliers, etc. They take it out or hit it with a hammer to bend it.

このためコンクリート表面に釘の錆が流出して特に打放
しの場合のコンクリート構造物の表面が汚れ、不体裁に
なる。As a result, the rust from the nails flows out onto the concrete surface, making the surface of the concrete structure especially in the case of an exposed concrete structure dirty and unsightly.
