【発明が解決しようとする課題】上記装置は、支柱に直
接ロープ支承用突出部を設けるため、支柱の板厚が厚く
なるとロープ支承用突出部を形成することが困難になる
と共に、支柱がパイプ形状になるとロープ支承用突出部
を形成することが不可能となる。In the above apparatus, since the rope supporting projection is provided directly on the column, it becomes difficult to form the rope supporting projection when the thickness of the column is large, and the column is formed of a pipe. The shape makes it impossible to form the rope support projection.

への滑りに対しては固定が不可能である。Further, in the above device, since the wire rope is tightened and fixed in a bent state, the wire rope is slid in the lateral direction of the wire rope with respect to the rope fixing support column by the rope supporting protrusions on both sides of the U-bolt. Can be fixed so that it does not move, but the vertical direction of the wire rope (vertical direction)
It cannot be fixed against slipping to.

ものである。According to the present invention, a pair of upper and lower holes are drilled at regular intervals in a vertical direction in a rope fixing support column of a rock fall prevention fence. A pair of upper and lower bolt insertion holes are drilled, and a cylindrical fitting projection is formed on the back surface of the bolt insertion hole to be fitted in the hole of the rope fixing support column. A plate-shaped metal fitting having a rope supporting protrusion formed thereon is abutted on the hole of the rope fixing support column, and a wire rope for rock fall prevention is laid between the rope supporting protrusions of the plate-shaped metal fitting, The wire rope and the plate-like metal fitting are fastened to the rope fixing column by U-bolts.

ヤロープをロープ止着用支柱に固定できる。The operation of the device of the present invention will be described. Since the plate-like metal fitting is provided with the bolt insertion hole and the rope bearing protrusion, and the rope fixing column is not directly provided with these, the rope bearing protrusion is not provided. It is possible to easily fix the wire rope to the rope fastening post even when the rope fastening post is a thick steel plate that is difficult or impossible to process or even in the case of a pipe shape.

上下方向への滑り動きを阻止される。Further, a concave portion is formed in the vicinity of the central portion of the rope supporting protrusion, and the wire rope is fitted into the concave portion. Therefore, the wire rope slides vertically in the U-bolt and the concave portions on both sides thereof. Will be blocked.
【００１２】そして、凹部の底部は板状金具の表面中央
部よりも突出しているため、ワイヤロープは両側の凹部
間でＵボルトにより屈曲状態で止着されるので、横方向
への滑り動きも阻止される。Since the bottom of the recess protrudes from the central portion of the surface of the plate-like metal fitting, the wire rope is fixed in a bent state by U bolts between the recesses on both sides, so that the sliding movement in the lateral direction is also possible. Be blocked.

一体性が増し、ワイヤロープの固定も堅固となる。[0013] Further, since the back surface of the bolt insertion hole of the plate-shaped metal fitting is formed in a fitting projection that fits into the hole of the rope fixing support, the work of attaching the plate-shaped metal fitting to the rope fixing support is easy. In addition to this, the integrity of the rope fixing support column and the plate-like metal fitting is increased, and the fixing of the wire rope is also firm.

ことのできる有用な発明である。According to the present invention, the rope supporting projection is not formed directly on the rope fixing support column as in the prior art, but is formed on the plate-shaped metal fitting separately from the rope fixing support column. The wire rope can also be fixed to a thick steel plate rope fixing post or a pipe-shaped rope fixing post in which it is difficult or impossible to form the wire rope so that the wire rope does not move in the horizontal and vertical directions. Since the fitting projection on the back surface of the plate-shaped metal fitting is fitted in the hole of the rope fixing column, the integrity of the plate-shaped metal fitting and the rope column is also strong. Therefore, even if a large impact is applied to the rock fall, the vertical spacing of the wire rope is prevented from expanding, and there is no fear of breaking the wire mesh, which is a useful invention capable of preventing the danger.
