Description
,27の間により構成され、前記ガイド溝26は円周方向等間隔で複数箇所設けられ、この例では3箇所に設けられている。また、前記案内プレート27は、鍔部25側から接続管23の端部側に向って低くなる傾斜縁部27Aを有している。さらに、図2に示すように、支柱上部2Uの鋼管12の下端側内面には、前記ガイド溝26に挿入する細長なガイド突条28が設けられ、このガイド突条28は、前記案内プレート27とほぼ同一長さを有し、鋼管12の端部から内部側に向って高くなる傾斜縁部28Aを有する。
また、実施例上の効果として、支柱2の長さ方向に長い補強体13の端部により先端受部31Sを構成し、両者の隙間に接合剤42を充填したから、連結強度に優れたものとなる。
