用したものである。(Means for Solving the Problem) A plurality of steel wire ropes are installed between stanchions arranged at a predetermined interval, and further, a wire mesh is anchored in a rockfall prevention fence in which a wire mesh is stretched between these steel wire ropes. As a structure, the base of the wire mesh holding metal fitting in which the tip of the base portion is formed into a hook shape portion is fastened to one side of the web of the pillar with a fastening device such as a bolt, and further, the wire mesh is attached to the hook shape portion of the wire mesh holding metal fitting. The wire mesh locking plate for locking the wire mesh is inserted to fix the wire mesh.
（作用） 本考案の防止柵によれば、支柱に穿設する透孔はウエブ
に穿設するようにしているので、従来例にあるように左
右使い勝手が規制されることがなく、従って、左右端末
支柱の配設上の方向規制がなくなる。(Operation) According to the prevention fence of the present invention, since the through holes formed in the support columns are formed in the web, the left and right usability is not restricted as in the conventional example, and therefore the left and right sides are not restricted. There is no restriction on the direction of the terminal support.
また、金網を直接係止する係止板にはボルト等の貫通孔
を穿孔する必要がないから、金網係止板に穿孔した透孔
との孔のセンターリング操作や孔の修正加工が不要とな
る。In addition, since it is not necessary to drill through holes such as bolts in the locking plate that directly locks the wire mesh, there is no need to perform centering operation of holes and correction processing of holes with the through holes drilled in the wire mesh locking plate. Become.
従って、金網の定着の施工が簡便となるばかりでなく、
支柱自体の左右使い勝手の規制がない。Therefore, not only is the construction of fixing the wire mesh easy,
There are no restrictions on the left and right of the columns themselves.
