INTERMEDIATE PILLAR FOR ROCKFALL PREVENTION FENCE AND ROCKFALL PREVENTION FENCE
To prevent a cable and a wire mesh from getting caught in a closure portion of an intermediate pillar, thereby preventing an absorption of an impact energy from falling rocks from being hindered in a rockfall prevention fence.SOLUTION: An intermediate pillar 9 of a rockfall prevention fence 1 includes a pillar body 22, a first axial direction movement restriction portion 35 including a first outer end surface 41, and a second axial direction movement restriction portion 36 including a second outer end surface 51. The first and second axial direction movement restriction portions 35, 36 protrude from an outer surface of the pillar body 22 to define a reception space 26 of a cable intermediate portion 3a. The first axial direction movement restriction portion 35 includes the first outer end surface 41, and the first outer end surface 41 includes a first outer end surface curve surface portion 41a. The second axial direction movement restriction portion 36 includes the second outer end surface 51, and the second outer end surface 51 includes a second outer end surface curve surface portion 51a.SELECTED DRAWING: Figure 5
【課題】落石防止柵において、ケーブル及び金網が中間支柱の閉込部に引っかかって落石の衝撃エネルギの吸収が阻害されるのを防ぐ。【解決手段】落石防止柵１の中間支柱９は、支柱本体２２と、第１外端面４１を有する第１軸方向移動制限部３５と、第２外端面５１を有する第２軸方向移動制限部３６と、を備える。第１及び第２軸方向移動制限部３５，３６は、支柱本体２２の外面から突出してケーブル中間部３ａの受入空間２６を画定する。第１軸方向移動制限部３５は第１外端面４１を有し、第１外端面４１は第１外端面曲面部４１ａを有する。第２軸方向移動制限部３６は第２外端面５１を有し、第２外端面５１は第２外端面曲面部５１ａを有する。【選択図】図５
