本考案は線条体とりわけガードケーブル、歩道用ガードケーブル、市街地の自 動車衝突等からの歩行者保護フェンス、建築物の道路に面した壁補強補助材、ブ テックなどにおけるインテリアケーブル、物干しなどの物品の吊り部材などに使 用するのに適した張力調整可能な線条体に関する。 INDUSTRIAL APPLICABILITY The present invention is applicable to strips, especially guard cables, guard cables for sidewalks, pedestrian protection fences from collisions of automobiles in urban areas, auxiliary materials for wall reinforcements facing roads in buildings, interior cables in buttes, etc. The present invention relates to a linear member with adjustable tension suitable for use as a hanging member for articles.

線条体とりわけ引張り強さが１７０kg/cm2を越えるワイヤロープ、鋼より線、 鋼線などは、ガードケーブル、歩道用ガードケーブル、市街地のフェンス、建築 物の補強材、物干しなどの物品の吊り部材などに利用されている。 この場合、線条体は両端が物体に留められることが必要であるが、棒材などと 違ってそれ自体に端末機構を持てないため、端末加工が施される。その端末加工 はアイスプライス、シングルロック、ソケット(くさびどめ)など種々の方法があ る。しかし、これらは線条体を他物に取付けることは可能であっても、線条体の 張力を任意に調整することができない。このため、従来では現場で適正長さを計 測し、それに応じて端末加工を施すことが必要であり、大がかりで時間がかかる という問題や、加工に特殊な技術を要し、したがってバラツキが大きいという問 題があった。 実公昭３７−８７２７号公報には、ワイヤロープの端末をくさびどめした端末 金具の後端に取付けボルトを嵌めて抜け止め用ナットを螺合し、取付けボルトの 先端側を支柱などに通した後、締付けナットを螺合し、その締付けナットの回動 によって端末金具を牽引しワイヤロープの張力を調整することが提案されている 。しかしこの構造では、端末金具から取付けボルトが長く突出するため、全体が 大型化する点と、外観や体裁が悪い点に問題があった。 本考案は前記のような問題点を解消するために考案されたもので、その目的と するところは、コンパクトな構造で、かつ線条体本体に不当なねじりを与えずに 簡単に張力の調整を行うことができる張力調整可能な線条体を提供することにあ る。Wires, especially wire ropes with a tensile strength of over 170 kg / cm 2 , stranded steel wires, steel wires, etc., guard cables, sidewalk guard cables, urban fences, building reinforcements, clothes hanging etc. It is used for materials. In this case, it is necessary for both ends of the filament to be fastened to the object, but unlike a bar or the like, since it cannot have a terminal mechanism itself, it is subjected to terminal processing. There are various methods for processing the terminal such as ice price, single lock, and socket (wedge). However, although they can attach the filament to other objects, they cannot adjust the tension of the filament arbitrarily. For this reason, conventionally, it is necessary to measure an appropriate length on site and perform terminal processing accordingly, which is a large and time-consuming problem, and requires special technology for processing, resulting in large variations. There was a problem. In Japanese Utility Model Publication No. 37-8727, a mounting bolt is fitted to the rear end of a terminal metal fitting of a wire rope that is wedged, a retaining nut is screwed, and the tip end of the mounting bolt is passed through a column or the like. After that, it is proposed that the tightening nut is screwed and the terminal metal fitting is pulled by rotating the tightening nut to adjust the tension of the wire rope. However, in this structure, since the mounting bolts project from the terminal fittings for a long time, there are problems in that the overall size becomes large and the appearance and appearance are not good. The present invention was devised to solve the above-mentioned problems, and its purpose is to have a compact structure and to easily adjust tension without giving undue twist to the filament body. The purpose of the present invention is to provide a filament body whose tension can be adjusted.

次に実施例に示すものの使用法と作用を説明する。 図４は本考案を自動車等の衝突のエネルギーをケーブルおよび支柱で吸収して 歩道の歩行者の安全を確保する歩道用のガードフェンスに適用した例を示してい る。７は地面に下部が埋設された支柱、８は支柱７，７間に張設された金網であ る。 この実施例に適用した場合、取付け金具３，３’の反支壁側はブラケットとし て任意の方法たとえばボルト９などにより支柱７，７に固定される。 そして、線条体本体１の張力を調整するには、図１のように、端末定着部２の 突起部２ｂが取付け金具３の異形穴３１に合致するように方向を調整し、角ナッ ト４をスパナやレンチなどの工具でつかみ回動すればよい。この操作は取付け金 具３内に工具を挿入する必要がないため容易である。 角ナット４を回動すれば、角ナット４は雄ねじ４０が取付け金具３の雌ねじ３ ０に螺合するため取付け金具３の軸線方向に進入して行く。これにより角ナット ４の支持穴４１にはめられている端末定着部２は角ナット４の回転に応じて軸線 方向に移動し、線条体本体１に張力が与えられる。 Next, the usage and action of the one shown in the embodiment will be described. Fig. 4 shows an example in which the present invention is applied to a sidewalk guard fence that secures the safety of pedestrians on the sidewalk by absorbing the energy of the collision of an automobile or the like with cables and columns. Reference numeral 7 is a pillar whose lower part is buried in the ground, and 8 is a wire net stretched between the pillars 7, 7. When applied to this embodiment, the anti-support wall side of the fittings 3, 3'is fixed as a bracket to the columns 7, 7 by an arbitrary method such as a bolt 9. Then, in order to adjust the tension of the filamentous body 1, as shown in FIG. It suffices to grasp 4 with a tool such as a spanner or a wrench and rotate it. This operation is easy because it is not necessary to insert a tool into the mounting tool 3. When the square nut 4 is rotated, the male screw 40 of the square nut 4 is screwed into the female screw 30 of the fitting 3, so that the nut 4 moves in the axial direction of the fitting 3. As a result, the terminal fixing portion 2 fitted in the support hole 41 of the square nut 4 moves in the axial direction according to the rotation of the square nut 4, and the tension is applied to the filament body 1.
【０００８】 このとき、端末定着部２は、端面が支持穴４１の座金ないしベアリング５に接 しているため、角ナット４の回転を妨げず、しかも、端末定着部２は少なくとも ２面に直線面を持つ断面形状の突起部２ｂが取付け金具３の支壁３０に設けた異 形穴３１に嵌合しているため、端末定着部２は回転しない。したがって、線条体 本体１にねじれが生じず、良好な特性が確保される。 工場生産で端末定着部２，２’が作られ、これが角ナット４と組み合わされて いるため品質や寸法精度のバラツキが少なく、取付け先の形状に合った取付け金 具３，３’を選択することで簡単かつ確実に張力調整を行える。At this time, since the end fixing portion 2 is in contact with the washer or bearing 5 of the support hole 41 at the end surface, the rotation of the square nut 4 is not hindered, and the terminal fixing portion 2 is linear on at least two surfaces. Since the protruding portion 2b having a cross-sectional shape having a surface is fitted into the irregular hole 31 provided in the support wall 30 of the mounting member 3, the terminal fixing portion 2 does not rotate. Therefore, the filament main body 1 is not twisted and good characteristics are secured. The terminal fixing parts 2 and 2'are made by factory production, and since these are combined with the square nut 4, there is little variation in quality and dimensional accuracy, and the mounting metal fittings 3 and 3'that match the shape of the mounting destination are selected. This allows tension adjustment to be performed easily and reliably.
