本発明を実施するための形態について、図面を参照しながら説明する。
ここでは、本発明による弾性緩衝部材を係留材Aに適用した場合を例に挙げて、以下詳細に説明する。例えば、図3に示すように、浮桟橋などの浮揚構造物Cを海底に設置されたアンカーBに係留する場合や、図4に示すように、フローティングネットなどの浮揚構造物C’を陸上に設置されたアンカーB’に係留する場合に、本係留材Aを用いる。
Embodiments for carrying out the present invention will be described with reference to the drawings.
Here, the case where the elastic buffer member according to the present invention is applied to the mooring material A will be described in detail as an example. For example, as shown in FIG. 3, when a floating structure C such as a floating pier is moored to an anchor B installed on the seabed, or as shown in FIG. 4, a floating structure C ′ such as a floating net is placed on land. The mooring material A is used when mooring to the installed anchor B ′.

この係留材Aは、摺れる長さや伸縮させるべき長さに応じて適宜の長さにして用いることができる。この係留材Aの内部構造を示す図2に示すように、係留材Aの中心部分には芯材1を備え、この芯材1に1本の補強材2が螺旋状に巻き付けられており、前記芯材1と螺旋状の補強材2の周囲を弾性材3で被覆してある。   The mooring material A can be used in an appropriate length according to the length to be slid and the length to be expanded and contracted. As shown in FIG. 2 showing the internal structure of the mooring material A, the mooring material A includes a core material 1 at the center thereof, and one reinforcing material 2 is wound around the core material 1 in a spiral shape. The core material 1 and the spiral reinforcing material 2 are covered with an elastic material 3.

一体構造のこの係留材Aによれば、芯材1と螺旋状の補強材2の周囲を弾性材3で被覆してあるので、弾性を有するのみならず、耐摩耗性、耐衝撃性に優れ、さらに、緩衝機能にも優れており、極めて簡易な一体構造のものである。   According to the mooring material A having an integral structure, the periphery of the core material 1 and the spiral reinforcing material 2 is covered with the elastic material 3, so that it not only has elasticity but also has excellent wear resistance and impact resistance. Furthermore, it has an excellent buffering function and has an extremely simple integrated structure.

また、浮桟橋などの浮揚構造物CをアンカーBに係留するために本係留材Aを用いた場合において、本係留材Aに耐摩耗性と耐衝撃性を付加したことにより、浮揚構造物Cの安全性を向上させることもできる。   In addition, when the mooring material A is used to moor the floating structure C such as a floating pier to the anchor B, the floating structure C is obtained by adding wear resistance and impact resistance to the mooring material A. It is also possible to improve safety.

ところで、この係留材Aの緩衝機能は、本係留材Aへの引張荷重作用時において、ワイヤからなる補強材2が螺旋状から直線状になってその外側を被覆している弾性材3が変形することによるものであり、それによってこの係留材Aが緩衝機能を十二分に発揮する。引張力が小さくなると、元の状態に戻る。   By the way, the buffering function of the mooring material A is that the elastic material 3 covering the outside of the reinforcing material 2 made of wire is deformed from a spiral shape when the tensile load is applied to the mooring material A. As a result, the anchoring material A fully exhibits a buffering function. When the tensile force decreases, the original state is restored.

前記芯材1をゴム製とすることができる。また、補強材2をワイヤからなるものとすることができる。さらに、弾性材3を合成ゴム製とすることができる。芯材1、補強材2、弾性材3をこのような材質とした場合には、ゴム製の芯材1とこの芯材1に螺旋状に巻き付けられているワイヤからなる補強材2と両部材の周囲を被覆している合成ゴム製の弾性材3とが相俟って、一体構造の係留材Aの耐摩耗性能と耐衝撃性能とが大幅に向上する。
ゴムとしては、硬質ゴムあるいは軟質ゴムを用いることができる。硬質ゴムであれば、例えば硬度75、70、65程度のものを、軟質ゴムであれば、例えば硬度50、45、30程度のものを用いることができる。
The core material 1 can be made of rubber. Further, the reinforcing material 2 can be made of a wire. Furthermore, the elastic material 3 can be made of synthetic rubber. When the core material 1, the reinforcing material 2, and the elastic material 3 are made of such materials, the reinforcing material 2 composed of a rubber core material 1 and a wire spirally wound around the core material 1 and both members In combination with the elastic material 3 made of synthetic rubber covering the periphery of the rubber, the wear resistance performance and impact resistance performance of the monolithic mooring material A are greatly improved.
As rubber, hard rubber or soft rubber can be used. For example, a hard rubber having a hardness of about 75, 70, 65 may be used, and a soft rubber having a hardness of, for example, about 50, 45, 30 may be used.

このように、本係留材Aは、ゴム製の芯材1とこの芯材1に螺旋状に巻き付けられているワイヤからなる補強材2と両部材の周囲を被覆している合成ゴム製の弾性材3とからなるので、いわゆるゴムライニングワイヤと呼ぶこともできる。
なお、ゴム製の芯材1と合成ゴム製の弾性材3の硬度を適宜変えることにより、一体構造の係留材Aの変位量(伸縮量)、ならびに耐摩耗性能を適宜調整することができる。
As described above, the mooring material A is composed of a rubber core material 1, a reinforcing material 2 made of a wire spirally wound around the core material 1, and an elastic material made of synthetic rubber covering the periphery of both members. Since it consists of the material 3, it can also be called what is called a rubber lining wire.
In addition, by appropriately changing the hardness of the rubber core material 1 and the synthetic rubber elastic material 3, the displacement amount (stretching amount) of the monolithic mooring material A and the wear resistance can be adjusted as appropriate.

ここには、ワイヤからなる補強材2の両端を、合成ゴム製の弾性材3の両側から露出させてループ2a状とした場合が例示されている。このようにした場合には、一体構造の係留材A両端のループ2a部分を利用して、図3あるいは図4に示すように、係留すべきもの(浮桟橋などの浮揚構造物Cやフローティングネットなどの浮揚構造物C’)をアンカーB、B’に簡単に係留することができる。   Here, a case where both ends of the reinforcing material 2 made of a wire are exposed from both sides of the elastic material 3 made of synthetic rubber to form a loop 2a is illustrated. In this case, as shown in FIG. 3 or FIG. 4 using the loop 2a portions at both ends of the monolithic mooring material A, what is to be moored (floating structure C such as a floating bridge, floating net, etc. The floating structure C ′) can be easily moored to the anchors B and B ′.

このように、本発明による弾性緩衝部材の両端にはループ2aが形成されているので、上述したように係留材Aとして係留すべきものをアンカーB、B’に簡単に係留することができるほか、橋梁の落橋防止のために橋梁を本弾性緩衝部材で支えたり、耐震構造物を支持するに当ってそれらを本弾性緩衝部材で緊縛するのに、極めて便利である。   As described above, since the loop 2a is formed at both ends of the elastic cushioning member according to the present invention, what is to be anchored as the anchoring material A as described above can be easily anchored to the anchors B and B ′. It is very convenient to support the bridge with the elastic buffer member to prevent the bridge from falling down, and to bind them with the elastic buffer member when supporting the earthquake-resistant structure.
