STONE FALL GUARD FENCE
To provide a stone fall guard fence capable of suppressing expansion or breakage of a mesh size of a wire net due to first stone fall, resulting in dealing with subsequent stone fall with reliability.SOLUTION: It is provided with a pole 1 installed on a slanting surface, and a wire net 2 stretched out between the poles 1. The wire net 2 has an expansion margin part 8 which is formed by drawing a folding bar steel 7 toward the side of the pole 1 together with the wire net 2 to fold the end of the wire net 2. When a falling stone collides with the wire net 2, the wire net 2 expands by the length of the expansion margin part 8.SELECTED DRAWING: Figure 1
【課題】最初の落石による金網の目の広がりや破れを抑制することができる結果、続いて起こる落石に確実に対応することができる落石防護柵を提供すること。【解決手段】斜面に設置される支柱１と、支柱１間に張り渡される金網２とを備え、金網２は、折返し用棒鋼７を金網２とともに支柱１側に引き寄せて、金網２の端部を畳むことにより形成される伸び代部８を有し、落石が金網２に衝突した際に、金網２は、伸び代部８の長さ分だけ伸びる。【選択図】図１
