Description
【０００１】[0001]
本考案は、山間部の法面又は斜面に面した道路、鉄道の線路等に設置する落石 防止柵に於けるワイヤロープの固定装置に関するものである。 The present invention relates to a wire rope fixing device for a rockfall prevention fence installed on a road or a railway line facing a slope or slope in a mountain area.
【０００２】[0002]
従来、この種の落石防止柵に於けるワイヤロープの固定装置として、落石防止 用ワイヤロープを有する落石防止柵に於けるロープ保持部材に、ワイヤロープを 嵌入したＵボルトが挿通され、そのロープ保持部材にＵボルトの両側に於いてロ ープ支承用突出部が設けられ、両側の突出部の間でＵボルトによりワイヤロープ が屈曲状態で締付固定されているものが既に存在する（実公平１ー４４５８０号 公報）。 Conventionally, as a wire rope fixing device for a rockfall prevention fence of this type, a U bolt in which the wire rope is inserted is inserted into a rope holding member in a rockfall prevention fence having a wirefall prevention wire rope, and the rope holding There is already a member with rope support protrusions on both sides of the U-bolt, and the wire rope is clamped and fixed in a bent state by U-bolts between the protrusions on both sides (actual fairness). 1-444580).
【０００３】[0003]
上記装置は、ワイヤロープが屈曲状態で締付固定されているので、Ｕボルトの 両側の支承用突出部によりワイヤロープをロープ止着用支柱に対し、ワイヤロー プの横方向に滑り動かないように固定することはできるが、ワイヤロープの上下 方向（縦方向）への滑りに対しては固定が不可能である。 In the above device, since the wire rope is clamped and fixed in a bent state, the wire protrusions on both sides of the U-bolt are used to fix the wire rope to the rope fixing column so that it will not slide in the lateral direction of the wire rope. It is possible, but it is impossible to fix the wire rope against sliding in the vertical direction (longitudinal direction).
【０００４】 そのため、落石によってはワイヤロープに大きな衝撃が加わり、ワイヤロープ が伸び、ワイヤロープ間隔が落石により上下方向に広がって、落石により落石防 止柵の金網が破られる恐れがあった。Therefore, depending on the rockfall, a large impact is applied to the wire rope, the wire rope stretches, the wire rope interval spreads in the vertical direction due to the rockfall, and there is a risk that the wire mesh of the rockfall prevention fence is broken by the rockfall.
【０００５】 上記点より本考案は、落石防止柵の落石防止用のワイヤロープを横方向のみな らず、上下方向へ滑り動くことのないようロープ止着用支柱に止着することので きる固定装置を提供しようとするものである。From the above point of view, the present invention is a fixing device capable of fixing a wire rope for rockfall prevention of a rockfall prevention fence to a rope fixing strut so that it does not move in the vertical direction regardless of the lateral direction. Is to provide.

【課題を解決するための手段】 上記課題を解決するため本考案装置は、落石防止用のワイヤロープを有する落 石防止柵のロープ止着用支柱に、ワイヤロープを嵌入したＵボルトが挿通され、 そのロープ止着用支柱にＵボルトの両側に於いてロープ支承用突出部が設けられ 、両側の突出部の間でＵボルトによりワイヤロープが屈曲状態で締付固定されて いる落石防止柵に於いて、両側のロープ支承用突出部の中央部付近に凹部が設け られ、該凹部にワイヤロープが嵌入されると共に、凹部の底部は前記ロープ止着 用支柱の表面よりも突出していることを特徴とするものである。Means for Solving the Problems In order to solve the above problems, the device of the present invention is such that a U-bolt in which a wire rope is fitted is inserted into a rope fixing column of a rockfall prevention fence having a wire rope for rockfall prevention, In the rockfall prevention fence in which the rope fixing columns are provided with protrusions for rope support on both sides of the U bolt, and the wire rope is clamped and fixed in a bent state by the U bolt between the protrusions on both sides. A recess is provided in the vicinity of the center of the rope bearing protrusions on both sides, and a wire rope is inserted into the recess, and the bottom of the recess protrudes from the surface of the rope fastening column. To do.
【０００７】[0007]
本考案装置の作用を説明すれば、Ｕボルトの両側に設けたロープ支承用突出部 の中央部付近に凹部を形成し、その凹部にワイヤロープが嵌入しているため、ワ イヤロープはＵボルト及びその両側の凹部により上下方向への滑り動きを阻止さ れる。 The operation of the device of the present invention will be described. Since a concave portion is formed in the vicinity of the central portion of the rope supporting protrusions provided on both sides of the U bolt, and the wire rope is fitted into the concave portion, the wire rope is formed by the U bolt and The recesses on both sides prevent vertical sliding movement.
【０００８】 又、凹部の底部はロープ止着用支柱の表面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。Further, since the bottom of the recess protrudes from the surface of the rope fastening strut, the wire rope is fixed in a bent state by U bolts between the recesses on both sides, so that the wire rope slides in the lateral direction. Is also blocked.

以下、本考案装置の一実施例を図面に基づき説明する。 図１は本考案装置の一実施例を示す一部縦断側面図、図２は同上の横断平面図 、図３は同上の正面図、図４は本考案装置を施した落石防止柵の一部正面図であ る。 An embodiment of the device of the present invention will be described below with reference to the drawings. 1 is a partially longitudinal side view showing an embodiment of the device of the present invention, FIG. 2 is a transverse plan view of the same as above, FIG. 3 is a front view of the same as above, and FIG. 4 is a part of a rockfall prevention fence to which the device of the present invention is applied. It is a front view.
【００１０】 而して、図中１は端末支柱、２は中間支柱であり、端末支柱１及び中間支柱２ は下部が基礎３に埋め込まれて立設されている。 ４は中間支柱２に一定間隔を於いて配置したロープ止着用支柱である。ロープ 止着用支柱４は端末支柱１間に存在する中間支柱、補助中間支柱等の総ての支柱 状体を含み、これ等支柱の必要部に配置すればよい。In the figure, 1 is a terminal support, 2 is an intermediate support, and the lower ends of the terminal support 1 and the intermediate support 2 are embedded in a foundation 3 and are erected. Numeral 4 is a rope fastening strut that is arranged on the intermediate strut 2 at regular intervals. The rope fastening columns 4 include all column-shaped members such as intermediate columns and auxiliary intermediate columns existing between the terminal columns 1, and may be arranged at necessary parts of these columns.
【００１１】 ５は各中間支柱２の横方向にわたって張り渡された落石防止用のワイヤロープ であり、中間支柱２の上下方向に一定間隔を於いて設けられている。 又、各ワイヤロープ５の端部に索端金具６が設けられ、索端金具６に連結する ロット７が端末支柱１に挿通され、ナット８によりワイヤロープ５が緊張されて いる。Reference numeral 5 is a wire rope for rockfall prevention which is stretched across the lateral direction of each of the intermediate columns 2, and is provided at regular intervals in the vertical direction of the intermediate column 2. A wire end fitting 6 is provided at the end of each wire rope 5, a lot 7 connected to the wire end fitting 6 is inserted into the terminal support 1, and the wire rope 5 is tensioned by a nut 8.
【００１２】 又、ロープ止着用支柱４のワイヤロープ５との交叉部に上下一対のボルト挿通 孔９が穿設され、該ボルト挿通孔９の両側に中央部付近に凹部１０を設けたロー プ支承用突出部１１が形成されている。 そして、ワイヤロープ５を嵌入したＵボルト１２がボルト挿通孔９に挿通され 、Ｕボルト１２及びナット１３によりワイヤロープ５が左右のロット支承用突出 部１１の凹部１０に嵌入した状態で緊締されている。In addition, a pair of upper and lower bolt insertion holes 9 are formed in the intersection of the rope fastening support column 4 with the wire rope 5, and a recess 10 is provided on both sides of the bolt insertion hole 9 near the center. A bearing protrusion 11 is formed. Then, the U bolt 12 into which the wire rope 5 is inserted is inserted into the bolt insertion hole 9, and the U rope 12 and the nut 13 tighten the wire rope 5 in the recesses 10 of the left and right lot bearing protrusions 11. There is.
【００１３】 そして、凹部１０の底部１０Ａはロープ止着用支柱４の表面よりも突出してい る。よって、ワイヤロープ５は両側の凹部１０間にＵボルト１２及びナット１３ により屈曲状態で緊締される。 尚、図中１４はワイヤロープ５を中間支柱２との交叉部に止着するＵボルト、 １５は金網である。The bottom portion 10 A of the recess 10 projects beyond the surface of the rope fastening column 4. Therefore, the wire rope 5 is tightened in a bent state between the concave portions 10 on both sides by the U bolt 12 and the nut 13. In the figure, 14 is a U bolt for fixing the wire rope 5 to the intersection with the intermediate support 2, and 15 is a wire mesh.
【００１４】[0014]
本考案によれば、落石防止用のワイヤロープが、ロープ止着用支柱に止着した Ｕボルトの両側のロープ支承用突出部の凹部に嵌入しているため、上下方向に滑 り動くことはないと共に、凹部間に屈曲状態で緊締されるため、横方向にも滑り 動くことはなく、不動にロープ止着用支柱にワイヤロープは固定される。 よって、落石により大きな衝撃が加わっても、ワイヤロープの上下方向への間 隔が広がることが阻止され、金網が破られる恐れもなく、危険を未然に防止する ことのできる有用な考案である。 According to the present invention, since the wire rope for rock fall prevention is fitted in the concave portions of the rope bearing protrusions on both sides of the U bolt fixed to the rope fixing column, it does not slide vertically. At the same time, since the recesses are tightened in a bent state, they do not slide laterally, and the wire rope is fixedly fixed to the rope fastening column. Therefore, even if a large impact is applied by falling rocks, the vertical gap of the wire rope is prevented from widening, and there is no fear of breaking the wire mesh, and it is a useful device that can prevent danger in advance.
