PROBLEM TO BE SOLVED: To provide a protective fence capable of improving impact absorbing effect by a net body.SOLUTION: Support posts 3, 3A, 3B are erected on a slope at intervals, and a protective surface 4 is provided between these support posts 3, 3A, 3B. The protective surface 4 comprises a rhombic wire mesh 5 provided between a plurality of support posts 3, 3A, 3B, an upper lateral rope member 6, a lower lateral rope member 7, and a pair of oblique rope members 8, 9 arranged to intersect between the support posts 3, 3A, 3B. The lower portions of the support posts 3, 3A, 3B are fixed to a slope 2, and reinforcing materials are provided on the left and right inside the support post 3 at the end portions. When an impact force is applied to the protective surface 4 by falling rocks or the like, the rhombic wire mesh 5, the upper and lower lateral rope members 6, 7 and the oblique rope members 8, 9 are deformed, so that the impact force is absorbed. At this time, a force tending to fall down to the left and right center sides is applied to the end support post 3 in addition to the rear side; however, the bending resistance is improved by the reinforcing members provided on the left and right inside the support post 3 and the impact force absorbing effect of the protective surface 4 provided with the rhombic wire mesh 5 can be improved.SELECTED DRAWING: Figure 1
【課題】網体による衝撃吸収効果を向上することができる防護柵を提供する。【解決手段】斜面に間隔を置いて支柱３，３Ａ，３Ｂを立設し、これら支柱３，３Ａ，３Ｂの間に防護面４を設ける。防護面４は、複数の支柱３，３Ａ，３Ｂ間に設けた菱型金網５と、上横ロープ材６と、下横ロープ材７と、支柱３，３Ａ，３Ｂ間に交差して配置された対をなす斜めロープ材８，９とを備え、支柱３，３Ａ，３Ｂの下部を斜面２に固定し、端部の支柱３内の左右に補強材を設ける。防護面４に落石などにより衝撃力を受けると、菱型金網５、上，下横ロープ材６，７及び斜めロープ材８，９が変形することにより衝撃力が吸収される。この際、端部の支柱３には後側以外にも左右中央側に倒そうとする力が加わるが、支柱３内部の左右に設けた補強材により曲げ耐力が向上し、菱型金網５を備えた防護面４の衝撃力吸収効果を向上することできる。【選択図】図１
