SUPPORT POST FOR GUARD FENCE, AND GUARD FENCE
PROBLEM TO BE SOLVED: To provide a support post for a guard fence and the guard fence having a structure to enable the support post for the guard fence to be buried in a ground while reducing a generated noise.SOLUTION: A plurality of blade parts 42 is provided to protrude downward at a bottom edge part of an excavation member 4, in a circumferential direction leaving an interval, the excavation member having a fitting part 41 made of a cylindrical body. A through-hole 44 is provided on a side wall 43 of the fitting part 41. A fitting bolt B that is a fixture is inserted into the through-hole 44 of the fitting part 41 and an insertion hole 12 provided at a bottom edge part of a support post body 11 made of the cylindrical body, for fitting the excavation member 4 at the bottom edge part of the support post body 11 such that the blade part 42 protrudes from the bottom edge of the support post body 11.SELECTED DRAWING: Figure 1
【課題】防護柵用支柱を土中に埋設する際に、騒音の発生を低減させて埋設することができる構造を備えた防護柵用支柱及び防護柵を提供する。【解決手段】円筒体からなる取付部４１を備えた掘削部材４の下端部に、その周方向に沿って複数の刃部４２が間隔をあけて下方に突出して設けられ、前記取付部４１の側壁４３に透孔４４が設けられ、該取付部４１の透孔４４と、円筒体からなる支柱本体１１の下端部に設けられた挿通孔１２に固定具である取付ボルトＢが挿通されて、前記掘削部材４が前記支柱本体１１の下端部に、前記刃部４２が前記支柱本体１１の下端から突出するように取付ける。【選択図】 図１
