METHOD FOR FORMING STEEL BAR INSERTION HOLE OF PRECAST MEMBER, PRECAST MEMBER JOINING METHOD AND PRECAST MEMBER PRODUCTION METHOD
To provide: a method for forming a steel bar insertion hole of a precast member which makes the boundary of the steel bar insertion hole into a finish sufficient for expecting adhesion force to a steel bar without using a spiral type sheath tube and can realize cost reduction; a precast member joining method of inserting a steel bar into the steel bar insertion hole so as to be securely fixed; and a precast member.SOLUTION: Provided is a method for forming a steel bar insertion hole of a precast member in which a single tube 32 is inserted inside a synthetic resin flexible conduit tube 31 in which many irregularities in the tubular circumferential direction are repeatedly formed in the tubular longitudinal direction, to produce a flask material 30 for a steel bar insertion hole, the single tube is removed from a precast member which is produced by installing concrete in a flask for a precast member arranged with the flask material for a steel bar insertion hole and the synthetic resin flexible conduit tube is then removed to eliminate the flask material for a steel bar insertion hole, so that a steel bar insertion hole in which irregularities corresponding to the irregularities of the synthetic resin flexible conduit tube are formed on its inner circumferential face is formed at the precast member.SELECTED DRAWING: Figure 1
【課題】スパイラル形のシース管を用いずに、鉄筋挿入孔の界面を鉄筋への付着力が期待できる仕上げとし、低コスト化を実現可能なプレキャスト部材の鉄筋挿入孔の形成方法、その鉄筋挿入孔に鉄筋を挿入し確実に定着させるプレキャスト部材の接合方法およびプレキャスト部材を提供する。【解決手段】このプレキャスト部材の鉄筋挿入孔の形成方法は、管周方向の凹凸が管長手方向に繰り返し多数形成された合成樹脂製可撓電線管３１の内側に単管３２を挿入して鉄筋挿入孔用型枠材３０を作製し、鉄筋挿入孔用型枠材を配置したプレキャスト部材用型枠にコンクリートを打設して作製されたプレキャスト部材から単管を取り外し合成樹脂製可撓電線管を取り外すことで鉄筋挿入孔用型枠材を除去することにより合成樹脂製可撓電線管の凹凸に対応した凹凸が内周面に形成された鉄筋挿入孔をプレキャスト部材に形成する。【選択図】図１
