INTERMEDIATE SUPPORT FOR ROCK FALL PREVENTION FENCE AND ROCK FALL PREVENTION FENCE
To prevent a cable and a wire net from being caught by confining parts of an intermediate supports to obstruct absorption of impact energy of falling rocks.SOLUTION: A confining part 24 for confining a cable intermediate part installed on an intermediate support comprises a first axial direction movement limiting part 35 having a first outer end surface 41 and a first opposed surface 43 and a second axial direction movement limiting part 36 having a second outer end surface 51 and a second opposed surface 53; the first outer end surface 41 has a first outer end surface curved portion 41a which is a convex surface that approaches a support main body 22 as it moves toward both outsides of the first axial movement limiting part 35; the first opposed surface 43 has a first opposed surface curved part 43a which is a convex surface that moves away from the second axial movement limiting part 36 as it moves toward both outsides of the first axial movement limiting part 35; the second outer end surface 51 has a second outer end surface curved surface part 51a which is a convex surface approaching the support main body 22 toward both outer sides of the second axial direction movement limiting part 36; and the second opposed surface 53 has a second opposed surface curved part 53a which is a convex surface that moves away from the first axial movement limiting part 35 as it moves toward both outer sides of the second axial direction movement limiting part 36.SELECTED DRAWING: Figure 5
【課題】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】閉込部２４は、第１外端面４１及び第１対向面４３を有する第１軸方向移動制限部３５と、第２外端面５１及び第２対向面５３を有する第２軸方向移動制限部３６とを有し、第１外端面４１は第１軸方向移動制限部３５の両外側へ向かうにつれて支柱本体２２へ近づく凸面である第１外端面曲面部４１ａを有し、第１対向面４３は第１軸方向移動制限部３５の両外側へ向かうにつれて第２軸方向移動制限部３６から遠ざかる凸面である第１対向面曲面部４３ａを有し、第２外端面５１は第２軸方向移動制限部３６の両外側へ向かうにつれて支柱本体２２へ近づく凸面である第２外端面曲面部５１ａを有し、第２対向面５３は第２軸方向移動制限部３６の両外側へ向かうにつれて第１軸方向移動制限部３５から遠ざかる凸面である第２対向面曲面部５３ａを有する。【選択図】図５
