COMPOSITE COLUMN STRUCTURE AND EXISTING CONCRETE COLUMN RENEWAL CONSTRUCTION METHOD
PROBLEM TO BE SOLVED: To provide a composite column structure and an existing concrete column renewal construction method that easily renew an overhead wiring pole, a power distribution pole or the like utilizing an existing concrete pole so as to prevent collapse or the like.SOLUTION: A composite colum structure 1 applied with the present invention is for renewing an existing concrete pole 7, and comprises an existing base 2 projecting from a ground surface 8a and a diameter-increased pipe 3 provided to cover the existing base 2. The existing base 2 is formed by cutting the existing concrete column 7. The diameter-increased pipe 3 has a diameter-decreased part 31 arranged above the existing base 2 and the diameter-increased part 32 made larger in diameter than the diameter-decreased part 31, and a temporally hardening material 4 is charged inside the diameter-increased part 32 covered with the existing base 2.SELECTED DRAWING: Figure 4
【課題】既設のコンクリート柱を利用して、架線柱、配電柱等を容易に更新して倒壊等を防止することのできる複合柱構造及び既設コンクリート柱更新工法を提供する。【解決手段】本発明を適用した複合柱構造１は、既設のコンクリート柱７を更新するためのものであり、地盤面８ａから突出した既設基部２と、既設基部２を覆うように設けられる拡径管３とを備える。既設基部２は、既設のコンクリート柱７を切断することにより形成される。拡径管３は、既設基部２の上方に配置される縮径部３１と、縮径部３１よりも内径を大きくした拡径部３２とを有し、既設基部２に被せられた拡径部３２の内側に、経時硬化性材料４が充填される。【選択図】図４
