SUPPORT COLUMN INSTALLATION STRUCTURE AND GUARD FENCE
PROBLEM TO BE SOLVED: To provide a guard fence which is light weight, capable of mitigating impact during a vehicle collision, and having the necessary load bearing capability for vehicle impacts, and to provide a support column installation structure appropriate for said guard fence.SOLUTION: A support column installation structure of the present invention is composed of a structure in which a buried portion of a support column is inserted into an underground pipe buried in a recess of a concrete floor slab, and a gap-filler is filled in a space between the support column and the underground pipe. A structure in which a base member having a standing pipe is fixed to the concrete floor slab, the buried portion of the support column is inserted into the standing pipe, and a gap-filler is filled in a space between the support column and the standing pipe is also possible. The hardness of the gap-filler is lower than the hardness of the concrete made concrete floor slab. For a guard fence of the present invention, a plurality of the support columns provided with the support column installation structure are installed in a bridge axial direction, and the support columns are connected with one or more horizontal tie members. For balustrade bodies, connecting via joint parts respectively installed on the balustrade bodies is also possible.SELECTED DRAWING: Figure 1
【課題】 軽量であり、車両衝突時の衝撃を緩和でき、車両衝突に対して必要な耐荷力を備えた防護柵と、当該防護柵に適した支柱設置構造を提供する。【解決手段】 本発明の支柱設置構造は、コンクリート床版の凹部に埋設された埋設管に支柱の埋設部が差し込まれ、その支柱と埋設管の間に間詰め材が充填された構造である。立設管を備えたベース部材がコンクリート床版に固定され、その立設管に支柱の埋設部が差し込まれ、その支柱と立設管との間に間詰め材が充填された構造とすることもできる。間詰め材の強度はコンクリート製のコンクリート床版の強度よりも低いものとしてある。本発明の防護柵は、前記支柱設置構造を備えた支柱が橋軸方向に複数本設けられ、それら支柱が一又は二以上の横つなぎ材で連結されたものである。高欄本体同士は、それぞれの高欄本体に設けられた継手部を用いて連結することもできる。【選択図】図１
