To provide a permanent form made by using thinnings which can prevent leakage of concrete and mortar through timber gaps, in which the amount of concrete members can be reduced, and concrete can be used for connecting timbers compared with the conventional concrete permanent form.SOLUTION: A permanent form comprises: a plate-like continuous object formed by bonding multiple square timbers or two-sided cant of almost the same size formed of undried timber by applying predetermined pressing force; a dowel buried in a rear face side of the square timbers or the two-sided cant in the longitudinal direction with a predetermined density at almost the same intervals; and a concrete plate placed in contact with the plate-like continuous object and integrated with the plate-like continuous object in curing with the dowel.SELECTED DRAWING: Figure 1
【課題】間伐材を利用した残存型枠として、木材間からのコンクリートやモルタルの漏れを防ぐとともに、従来のコンクリート製残存型枠に対して、コンクリート部材の量を軽減するとともにコンクリートを木材間の連結に利用する。【解決手段】未乾燥の木材から生成された複数の略同一寸法の角材若しくはタイコ材に所定の押圧力を加えて着接する板状の連続体と、前記角材若しくはタイコ材の背面側に、長手方向に所定の密度で略等間隔に埋め込まれたジベルと、前記板状の連続体に着接して打設され、前記ジベルによって硬化時に前記板状の連続体と一体になるコンクリート板と、を備えた残存型枠。【選択図】図１
