Zusammenfassung: | To provide an erection structure of a columnar support which is easy in the positioning of pipes constituting the columnar support, can surely connect the pipes, can easily remove the pipes at dismantling, and facilitated in storage, and a rising motion auxiliary tool having the structure.SOLUTION: An erection structure of a columnar support has: a base member 20 for erecting a columnar support 10; a fastening member 40 having a diameter-contracted part 46 at an internal peripheral face; a pipe lock member 50 having a tapered face 54 which is tapered toward a tip, and arranged between a frame pipe 11 and the fastening member 40, and a presser cap 60 screwed to an upper end of the fastening member 40 in a state where the frame pipe 11 is inserted therein. When fastening the presser cap 60, the tapered face 54 of the pipe lock member 50 presses the diameter-contracted part 46 of the fastening member 40 in a radial direction, the frame pipe 11 is thereby positioned and fixed to a stand pipe 12, and when releasing the fastening of the presser cap 60, the positioning and the fixation of the frame pipe 11 are released.SELECTED DRAWING: Figure 2
【課題】、支柱を構成するパイプ同士の位置決めが簡単で且つ確実に連結し、また分解時には容易に取り外すことができ、更には保管し易くした支柱の立設構造及びその構造を有する立ち上がり動作補助具を創出することを課題とする。【解決手段】支柱10を立設させるベース部材20と、内周面に縮径部46を有する締付け部材40と、先端に向かって先細るテーパー面54を有してフレームパイプ11と締付け部材40との間に配置されるパイプ止め部材50と、内部にフレームパイプ11を挿通した状態で締付け部材40の上端に螺着される抑えキャップ60と、を有し、抑えキャップ60を締め付けるとパイプ止め部材50のテーパー面54が締付け部材40の縮径部46を径方向に押圧することで、スタンドパイプ12に対するフレームパイプ11の位置決め固定が行われ、抑えキャップ60の締め付けを緩めるとフレームパイプ11の位置決め固定が解除される構成とする。【選択図】図2 |
