PROTECTIVE FENCE
To provide a protective fence for rock fall avalanche prevention that can reduce material costs while improving the workability of the protective fence.SOLUTION: A protective fence for rock fall avalanche prevention consists of a rigid frame structure 11 consisting of a rigid upper chord rod 25 laterally laid between the heads of a terminal support 20b and heads of one or more intermediate supports 20a adjacent to the terminal support, and a flexible frame structure 12 consisting of a flexible upper chord rope 28 laid in span units between the heads of the multiple intermediate supports 20a, and a load can be transmitted between the rigid frame structure 11 and the flexible frame structure 12 through the rigid structure upper chord 25 and the flexible upper chord rope 28 connected to the heads of the intermediate supports 20a.SELECTED DRAWING: Figure 1
【課題】防護柵の施工性を改善しつつ、資材コストを削減できる、落石雪崩予防兼用の防護柵を提供すること。【解決手段】端末支柱２０ｂと該端末支柱に隣り合う単数または複数の中間支柱２０ａの頭部間に剛構造の上弦杆２５を横架して構成する剛枠構造体１１と、複数の中間支柱２０ａの頭部間にスパン単位で柔構造の上弦索２８を架設して構成する柔枠構造体１２からなり、中間支柱２０ａの頭部に連結した剛構造の上弦杆２５および柔構造の上弦索２８を通じて剛枠構造体１１と柔枠構造体１２との間で荷重を伝達可能に構成した。【選択図】図１
