Claims (1)
- 建設業の型枠工事に於いての釘に関するものであり、通常、釘の胴部は先端部から頭部までストレートだが、長さが45mmの型枠専用釘は、頭部(1b)の下部に設けられた合板の厚みを考慮した首部(1a)が、頭部に向かって徐々に径を増し、テーパーを形成して、抜く時に抜き易く、効率の良い形状であって、首部(1a)と胴部(1)の境界には、ストレートな胴部(1)の径を僅かに上回る段差を設け、頭部(1b)から首部(1a)と胴部(1)の境界までの長さが8〜9mmである型枠専用釘であって、型枠解体作業では、合板(3)と桟木(4)を分離して合板(3)側に型枠専用釘が残った状態で、釘抜き作業は、釘の先端部(1c)を金槌で叩くと頭部(1b)とテーパーを形成する首部(1a)が瞬時に合板(3)から剥離、厚さ12mmの合板(3)と釘の接点は釘の胴部(1)の長さ3〜4mmの周囲だけになり、一気に釘を押し下げる事が出来、合板(2)の面まで釘の先端部(1c)を押し下げると合板と釘の接点は無くなり、抜けた状態になるものであり、型枠 解体時の釘抜き作業時間を大幅に短縮する事が出来る型枠専用釘。
