Description

本発明は、継ぎ手補助部材、継ぎ手構造部材、可動柵、継ぎ手補助部材および継ぎ手構造部材の製造方法に関するものであり、より特定的には、繊維強化プラスチック部材の他の部材との連結部に配置される継ぎ手補助部材、当該継ぎ手補助部材を備えた継ぎ手構造部材、継ぎ手構造部材を用いた可動柵、上記継ぎ手補助部材および継ぎ手構造部材の製造方法に関するものである。   The present invention relates to a joint auxiliary member, a joint structural member, a movable fence, a joint auxiliary member, and a method for manufacturing a joint structural member, and more specifically, disposed in a connecting portion with another member of a fiber reinforced plastic member. The present invention relates to a joint auxiliary member, a joint structural member provided with the joint auxiliary member, a movable fence using the joint structural member, the joint auxiliary member, and a method of manufacturing the joint structural member.

金属製品において構造部材を連結する方法としては、重ね合わせた構造部材をボルト、ピン、リベットなどの連結部材を用いて連結する方法が用いられている。また、近年では、設置性や作業性の向上という観点から構造部材のさらなる軽量化が求められている。その中で、構造部材に用いる材料として、金属製の材料に代わりより軽量な繊維強化プラスチックを用いることが進められている。繊維強化プラスチックと他の部材とを連結する方法としては、金属製の構造部材の場合と同様に、ボルト、ピンおよびリベットなどの連結部材を用いる方法が用いられている（たとえば、特許文献１参照）。しかし、繊維強化プラスチックは金属製の材料と比べて耐摩耗性が低いという特性を有するため、ネジ切り加工を施したり摺動部材を挿入することができない。そのため、繊維強化プラスチックと他の部材との継ぎ手部分には金属製の継ぎ手補助部材が挿入される。   As a method of connecting structural members in metal products, a method of connecting stacked structural members using connecting members such as bolts, pins, and rivets is used. In recent years, there has been a demand for further weight reduction of structural members from the viewpoint of improvement in installation property and workability. Among them, as a material used for the structural member, a lighter fiber-reinforced plastic is being used instead of a metal material. As a method of connecting the fiber reinforced plastic and another member, a method using a connecting member such as a bolt, a pin, and a rivet is used as in the case of a metal structural member (see, for example, Patent Document 1). ). However, since fiber reinforced plastic has a characteristic of low wear resistance compared to a metal material, it cannot be threaded or a sliding member cannot be inserted. Therefore, a metal joint auxiliary member is inserted into a joint portion between the fiber reinforced plastic and another member.

特開２００３−１８１８５０号公報JP 2003-181850 A

繊維強化プラスチックと他の部材との継ぎ手部分には、継ぎ手補助部材を挿入するための円孔部が形成される。この円孔部は、繊維強化プラスチックを成形した後に穴あけ加工を施すことにより形成される。また、繊維強化プラスチックと他の部材とを連結すると、この円孔部の壁面には、繊維強化プラスチックを圧縮する向きに外力が負荷される。さらに、円孔部を形成するために穴あけ加工を施すことにより、繊維強化プラスチック内の強化繊維が不連続となる。そのため、繊維強化プラスチックの円孔部の壁面の強度は、外力を受ける側に位置する壁面の圧縮特性（圧縮強度）が支配的となる。一般に、繊維強化プラスチックは引張強度に比べて圧縮強度が小さいという特性を有する。そのため、繊維強化プラスチックの継ぎ手部分に十分な強度を持たせるためには、継ぎ手部分において繊維強化プラスチックの厚みを増加させる必要が生じる。その結果、繊維強化プラスチック全体の重量の増加を招くという問題点が生じる。   A circular hole for inserting the joint auxiliary member is formed in the joint portion between the fiber reinforced plastic and the other member. This circular hole is formed by forming a fiber reinforced plastic and then drilling it. When the fiber reinforced plastic is connected to another member, an external force is applied to the wall surface of the circular hole portion in the direction in which the fiber reinforced plastic is compressed. Furthermore, the reinforced fiber in the fiber reinforced plastic becomes discontinuous by performing a drilling process to form a circular hole. Therefore, the strength of the wall surface of the circular hole portion of the fiber reinforced plastic is dominated by the compression characteristics (compression strength) of the wall surface located on the side receiving the external force. In general, fiber-reinforced plastic has a characteristic that its compressive strength is smaller than its tensile strength. Therefore, in order to give sufficient strength to the joint portion of the fiber reinforced plastic, it is necessary to increase the thickness of the fiber reinforced plastic at the joint portion. As a result, there arises a problem that the weight of the entire fiber reinforced plastic is increased.

本発明は上記の課題に鑑みてなされたものであり、繊維強化プラスチック部材の重量の増加を抑制しつつ、繊維強化プラスチック部材の他の部材との連結部の強度を向上させることができる、継ぎ手補助部材、当該継ぎ手補助部材を備えた継ぎ手構造部材、継ぎ手構造部材を用いた可動柵、上記継ぎ手補助部材および継ぎ手構造部材の製造方法を提供することを目的としている。   The present invention has been made in view of the above problems, and is a joint that can improve the strength of a connecting portion with another member of a fiber reinforced plastic member while suppressing an increase in the weight of the fiber reinforced plastic member. It is an object of the present invention to provide an auxiliary member, a joint structural member provided with the joint auxiliary member, a movable fence using the joint structural member, a method of manufacturing the joint auxiliary member, and the joint structural member.

本発明に従った継ぎ手補助部材は、繊維強化プラスチック部材の他の部材との連結部に配置される継ぎ手補助部材である。この継ぎ手補助部材は、環状部を有するベース部材と、環状部の外周面にその一部が巻き付けられた強化繊維束とを備えている。強化繊維束は環状部の外周面に巻き付けられた固定部と、外周面から離れるように延在する延在部とを含んでいる。固定部には、樹脂が含浸硬化されている。   The joint auxiliary member according to the present invention is a joint auxiliary member disposed at a connection portion with another member of the fiber reinforced plastic member. The joint auxiliary member includes a base member having an annular portion and a reinforcing fiber bundle having a part thereof wound around the outer peripheral surface of the annular portion. The reinforcing fiber bundle includes a fixed portion wound around the outer peripheral surface of the annular portion, and an extending portion extending away from the outer peripheral surface. The fixing portion is impregnated and cured with resin.

本発明に従った継ぎ手補助部材によれば、繊維強化プラスチック部材の重量の増加を抑制しつつ、繊維強化プラスチック部材の他の部材との連結部の強度を向上させることができる。   According to the joint auxiliary member according to the present invention, it is possible to improve the strength of the connecting portion with another member of the fiber reinforced plastic member while suppressing an increase in the weight of the fiber reinforced plastic member.

In the following drawings, the same or corresponding parts are denoted by the same reference numerals, and the description thereof will not be repeated.

（実施の形態１）
以下、本発明の実施の形態１について説明する。はじめに、実施の形態１に係る継ぎ手補助部材１の構造について図１〜４に基づいて説明する。実施の形態１に係る継ぎ手補助部材１は、繊維強化プラスチック部材の他の部材との連結部に配置される継ぎ手補助部材である。図１を参照して、継ぎ手補助部材１は、環状部を有するベース部材としてのボビン部材１０と、環状部の外周面１５にその一部が巻き付けられた強化繊維束２０とを備えている。強化繊維束２０はボビン部材１０の環状部の外周面１５に、張力が負荷されつつ少なくとも一周巻き付けられている。また、複数本の強化繊維束２０がボビン部材１０の環状部の外周面１５に巻き付けられていてもよい。 (Embodiment 1)
Embodiment 1 of the present invention will be described below. First, the structure of the joint auxiliary member 1 according to the first embodiment will be described with reference to FIGS. The joint auxiliary member 1 according to Embodiment 1 is a joint auxiliary member that is disposed at a connection portion with another member of the fiber-reinforced plastic member. Referring to FIG. 1, the joint auxiliary member 1 includes a bobbin member 10 as a base member having an annular portion, and a reinforcing fiber bundle 20 partially wrapped around an outer peripheral surface 15 of the annular portion. The reinforcing fiber bundle 20 is wound around the outer peripheral surface 15 of the annular portion of the bobbin member 10 at least once while tension is applied. A plurality of reinforcing fiber bundles 20 may be wound around the outer peripheral surface 15 of the annular portion of the bobbin member 10.

図２を参照して、ボビン部材１０は、環状部１１Ｂを有する第１ベース部材としてのメス型ボビン部材１１と、環状部１２Ｂを有し第１ベース部材に連結された第２ベース部材としてのオス型ボビン部材１２とを含んでいる。具体的には、ボビン部材１０はメス型ボビン部材１１とオス型ボビン部材１２との二つの部材より構成されている。そのため、たとえば継ぎ手補助部材１の製造においては、メス型ボビン部材１１およびオス型ボビン部材１２の各々の構成部材を別々に分けて取り扱うことができる。   Referring to FIG. 2, a bobbin member 10 has a female bobbin member 11 as a first base member having an annular portion 11B, and a second base member having an annular portion 12B and connected to the first base member. A male bobbin member 12. Specifically, the bobbin member 10 includes two members, a female bobbin member 11 and a male bobbin member 12. Therefore, for example, in manufacturing the joint auxiliary member 1, the constituent members of the female bobbin member 11 and the male bobbin member 12 can be handled separately.

メス型ボビン部材１１およびオス型ボビン部材１２はそれぞれ金属材料からなっており、たとえばアルミニウムやステンレス鋼からなっている。また、メス型ボビン部材１１とオス型ボビン部材１２との嵌め合わせ面１６を構成するメス型ボビン部材の嵌め合わせ表面１１Ａ、およびオス型ボビン部材の嵌め合わせ表面１２Ａのそれぞれには、嵌め合わせたメス型ボビン部材１１とオス型ボビン部材１２とが軸方向に抜けることを抑制するための加工が施されている。たとえば、メス型ボビン部材の嵌め合わせ表面１１Ａおよびオス型ボビン部材の嵌め合わせ表面１２Ａには、ネジ切り加工が施されている。メス型ボビン部材１１の環状部１１Ｂおよびオス型ボビン部材の環状部１２Ｂは、ボビン部材１０の環状部１０Ｂを構成する。   The female bobbin member 11 and the male bobbin member 12 are each made of a metal material, for example, aluminum or stainless steel. Further, the fitting surface 11A of the female bobbin member constituting the fitting surface 16 of the female bobbin member 11 and the male bobbin member 12 and the fitting surface 12A of the male bobbin member were fitted to each other. Processing is performed to prevent the female bobbin member 11 and the male bobbin member 12 from coming off in the axial direction. For example, threading is applied to the fitting surface 11A of the female bobbin member and the fitting surface 12A of the male bobbin member. The annular portion 11B of the female bobbin member 11 and the annular portion 12B of the male bobbin member constitute an annular portion 10B of the bobbin member 10.

なお、図３を参照して、メス型ボビン部材１１の環状部１１Ｂの外周面１５において、外周側に突出する突起部１３が形成されていてもよい。これにより、継ぎ手補助部材１の製造時においてメス型ボビン部材１１の環状部１１Ｂの外周面１５に巻き付けられた強化繊維束２０が軸方向に抜けることを抑制し、強化繊維束２０をより強固に固定することができる。   In addition, with reference to FIG. 3, the protrusion part 13 which protrudes in the outer peripheral side may be formed in the outer peripheral surface 15 of the annular part 11B of the female bobbin member 11. This suppresses the reinforcing fiber bundle 20 wound around the outer peripheral surface 15 of the annular portion 11B of the female bobbin member 11 during the manufacture of the joint auxiliary member 1 from being pulled out in the axial direction, thereby strengthening the reinforcing fiber bundle 20 more firmly. Can be fixed.

図２および図４を参照して、強化繊維束２０はメス型ボビン部材１１の環状部１１Ｂの外周面１５に巻き付けられた固定部２１と、その外周面１５から離れるように延在する延在部２２とを含んでいる。また、図４を参照して、強化繊維束２０の固定部２１には樹脂３０が含浸硬化されている。これにより、強化繊維束２０の固定部２１はメス型ボビン部材１１の環状部１１Ｂの外周面１５において強固に固定されている。   Referring to FIGS. 2 and 4, reinforcing fiber bundle 20 includes a fixed portion 21 wound around outer peripheral surface 15 of annular portion 11 </ b> B of female bobbin member 11, and an extension extending away from outer peripheral surface 15. Part 22. In addition, referring to FIG. 4, resin 30 is impregnated and cured on fixing portion 21 of reinforcing fiber bundle 20. Thereby, the fixing portion 21 of the reinforcing fiber bundle 20 is firmly fixed on the outer peripheral surface 15 of the annular portion 11B of the female bobbin member 11.

以上のように、実施の形態１に係る継ぎ手補助部材１において、強化繊維束２０はメス型ボビン部材１１の環状部１１Ｂの外周面１５に巻き付けられており、樹脂３０を含浸硬化することにより強固に固定された固定部２１と、メス型ボビン部材１１の環状部１１Ｂの外周面１５から離れるように延在する延在部２２とを含んでいる。この強化繊維束２０の延在部２２は、継ぎ手補助部材１を繊維強化プラスチック部材の他の部材との連結部に配置する場合、繊維強化プラスチック部材内にて連結部に負荷される外力の方向に沿った方向に延在するように固定される。これにより、繊維強化プラスチック部材の他の部材との連結部に負荷される外力に対して、延在部２２にはその外力に沿った向きの張力が発生する。そのため、繊維強化プラスチック部材の他の部材との連結部に配置された継ぎ手補助部材１は、負荷される外力に対して延在部２２に発生する張力により支持される。これにより、繊維強化プラスチック部材と他の部材との連結部への外力の負荷に対する強度向上のための対応として、繊維強化プラスチックの連結部付近の厚みを増加させる必要性が小さくなる。したがって、実施の形態１に係る継ぎ手補助部材１によれば、繊維強化プラスチックの重量の増加を抑制しつつ、繊維強化プラスチック部材の他の部材との連結部の強度を向上させることができる。   As described above, in the joint auxiliary member 1 according to the first embodiment, the reinforcing fiber bundle 20 is wound around the outer peripheral surface 15 of the annular portion 11B of the female bobbin member 11, and is firmly formed by impregnating and curing the resin 30. And a extending portion 22 that extends away from the outer peripheral surface 15 of the annular portion 11B of the female bobbin member 11. The extending portion 22 of the reinforcing fiber bundle 20 has a direction of an external force applied to the connecting portion in the fiber reinforced plastic member when the joint auxiliary member 1 is arranged at the connecting portion with another member of the fiber reinforced plastic member. It is fixed so as to extend in the direction along. Thereby, with respect to the external force applied to the connection portion with the other member of the fiber reinforced plastic member, a tension in the direction along the external force is generated in the extending portion 22. Therefore, the joint auxiliary member 1 disposed at the connection portion with the other member of the fiber reinforced plastic member is supported by the tension generated in the extending portion 22 with respect to the external force applied. This reduces the need to increase the thickness in the vicinity of the connection portion of the fiber reinforced plastic as a measure for improving the strength against the load of the external force applied to the connection portion between the fiber reinforced plastic member and the other member. Therefore, according to the joint auxiliary member 1 according to the first embodiment, it is possible to improve the strength of the connection portion with another member of the fiber reinforced plastic member while suppressing an increase in the weight of the fiber reinforced plastic.

次に、実施の形態１に係る継ぎ手構造部材２の構造について、図５〜１０に基づいて説明する。実施の形態１に係る継ぎ手構造部材２は、繊維強化プラスチック部材４２と、繊維強化プラスチック部材４２内に配置された継ぎ手補助部材１とを備えている。継ぎ手補助部材１は、上記の実施の形態１に係る継ぎ手補助部材１である。図５を参照して、継ぎ手補助部材１を構成するボビン部材１０の環状部１０Ｂの外周面１５には強化繊維束２０の一部が巻きつけられている。また、ボビン部材１０の内周側領域１４は貫通孔を構成している。この貫通孔は、ボルト、ピン、リベットなどの連結部材を挿入することが可能に構成されている。この貫通孔に連結部材を挿入することにより、継ぎ手構造部材２と他の部材とが連結される。   Next, the structure of the joint structural member 2 according to Embodiment 1 will be described with reference to FIGS. The joint structure member 2 according to Embodiment 1 includes a fiber reinforced plastic member 42 and a joint auxiliary member 1 disposed in the fiber reinforced plastic member 42. The joint auxiliary member 1 is the joint auxiliary member 1 according to the first embodiment. Referring to FIG. 5, a part of the reinforcing fiber bundle 20 is wound around the outer peripheral surface 15 of the annular portion 10 </ b> B of the bobbin member 10 constituting the joint auxiliary member 1. Further, the inner peripheral side region 14 of the bobbin member 10 constitutes a through hole. The through hole is configured to allow insertion of a connecting member such as a bolt, a pin, and a rivet. By inserting the connecting member into the through hole, the joint structure member 2 and the other member are connected.

図６を参照して、上記の継ぎ手補助部材１は繊維強化プラスチック部材４２内に埋め込まれるように配置されている。繊維強化プラスチック部材４２は、樹脂からなる母材部４０と母材部４０内に積層して配置された複数枚の強化繊維クロス４１とを含んでいる。また、強化繊維束２０の延在部２２は強化繊維クロス４１の層間に延在している。これにより、強化繊維束２０の延在部２２は繊維強化プラスチック部材４２内にて強固に固定される。   With reference to FIG. 6, the joint auxiliary member 1 is arranged so as to be embedded in the fiber reinforced plastic member 42. The fiber reinforced plastic member 42 includes a base material portion 40 made of a resin and a plurality of reinforcing fiber cloths 41 arranged in a stack in the base material portion 40. The extending portion 22 of the reinforcing fiber bundle 20 extends between the layers of the reinforcing fiber cloth 41. Thereby, the extending part 22 of the reinforcing fiber bundle 20 is firmly fixed in the fiber reinforced plastic member 42.

また、強化繊維束２０の延在部２２は、繊維強化プラスチック部材４２の他の部材との連結部に加えられる外力Ｆによる負荷を効率的に軽減するような方向に延在していることが好ましい。すなわち、図７および図８を参照して、強化繊維束２０の延在部２２は、繊維強化プラスチック部材４２の他の部材３との連結部に負荷されるべき外力Ｆの方向に沿った方向に延在していることが好ましい。より具体的には、強化繊維束２０の延在部２２は外力Ｆと逆の向きである矢印Ｄの向きに延在するように配置されることが好ましい。   Further, the extending portion 22 of the reinforcing fiber bundle 20 may extend in a direction that efficiently reduces the load caused by the external force F applied to the connecting portion with the other member of the fiber reinforced plastic member 42. preferable. That is, referring to FIG. 7 and FIG. 8, the extending portion 22 of the reinforcing fiber bundle 20 is a direction along the direction of the external force F to be applied to the connecting portion with the other member 3 of the fiber reinforced plastic member 42. It is preferable that it extends. More specifically, the extending portion 22 of the reinforcing fiber bundle 20 is preferably arranged so as to extend in the direction of the arrow D that is opposite to the external force F.

図６〜図１０を参照して、継ぎ手構造部材２と他の部材３とをたとえばボルト５０およびナット５１により連結した場合について説明する。この場合、連結部に外力Ｆが加えられると、継ぎ手構造部材２の連結部においては当該外力Ｆによる負荷に耐え得るための強度が必要となる。これに対して、強化繊維束２０の延在部２２を外力Ｆが負荷される向きと逆の向きに延在させることにより、延在部２２にて、外力Ｆが負荷される向きと逆の向きに張力Ｔを発生させることができる。これにより、繊維強化プラスチック部材４２の他の部材との連結部に加えられる外力Ｆによる負荷を効率的に軽減することが可能になる。その結果、継ぎ手構造部材２に外力Ｆによる負荷に耐え得るための強度を付与することが容易になる。   With reference to FIGS. 6 to 10, a case where the joint structural member 2 and the other member 3 are connected by, for example, a bolt 50 and a nut 51 will be described. In this case, when an external force F is applied to the connecting portion, the connecting portion of the joint structure member 2 needs to have strength to withstand a load caused by the external force F. In contrast, by extending the extending portion 22 of the reinforcing fiber bundle 20 in a direction opposite to the direction in which the external force F is loaded, the extending portion 22 has a direction opposite to the direction in which the external force F is loaded. A tension T can be generated in the direction. Thereby, it becomes possible to reduce efficiently the load by the external force F applied to the connection part with the other member of the fiber reinforced plastic member 42. As a result, it becomes easy to give the joint structure member 2 strength sufficient to withstand the load caused by the external force F.

次に、実施の形態１に係る継ぎ手補助部材の製造方法について、図１１〜１６に基づいて説明する。実施の形態１に係る継ぎ手補助部材１の製造方法は、繊維強化プラスチック部材の他の部材との連結部に配置される継ぎ手補助部材の製造方法であり、以下に示す工程により実施される。はじめに、環状部を有するベース部材としてのメス型ボビン部材１１および強化繊維束２０を準備する工程が実施される。メス型ボビン部材１１は少なくとも二つ準備される。強化繊維束２０は一本のみ準備されてもよいし、複数本準備されてもよい。   Next, a method for manufacturing the joint auxiliary member according to the first embodiment will be described with reference to FIGS. The method for manufacturing the joint auxiliary member 1 according to Embodiment 1 is a method for manufacturing a joint auxiliary member that is disposed at a connecting portion with another member of the fiber-reinforced plastic member, and is performed by the following steps. First, a step of preparing the female bobbin member 11 and the reinforcing fiber bundle 20 as a base member having an annular portion is performed. At least two female bobbin members 11 are prepared. Only one reinforcing fiber bundle 20 may be prepared, or a plurality of reinforcing fiber bundles 20 may be prepared.

図１１および図１２を参照して、準備された各々のメス型ボビン部材１１は、強化繊維束取付冶具６０に備えられた円柱部材６１に挿入される。これにより、各々のメス型ボビン部材１１は強化繊維束取付冶具６０上に保持される。   Referring to FIGS. 11 and 12, each prepared female bobbin member 11 is inserted into a cylindrical member 61 provided in a reinforcing fiber bundle attachment jig 60. Accordingly, each female bobbin member 11 is held on the reinforcing fiber bundle attachment jig 60.

次に、強化繊維束２０に張力αを負荷しつつ、メス型ボビン部材１１の環状部１１Ｂの外周面１５に強化繊維束２０の一部を巻き付ける工程が実施される。具体的には、図１３および図１４参照して、たとえば強化繊維束２０は一のメス型ボビン部材１１の環状部１１Ｂの外周面１５に少なくとも一周巻き付けられた後、隣り合うメス型ボビン部材１１の環状部１１Ｂの外周面１５に少なくとも一周巻き付けられる。この工程は少なくとも二回繰り返して実施されることが好ましい。これにより、強化繊維束２０には、メス型ボビン部材１１の環状部１１Ｂの外周面１５に巻き付けられた固定部２１と、外周面１５から離れるように延在する延在部２２と、端部２３とがそれぞれ形成される。また、複数本の強化繊維束２０が準備されている場合には、各々の強化繊維束２０がメス型ボビン部材１１の環状部１１Ｂの外周面１５に巻き付けられてもよい。   Next, a step of winding a part of the reinforcing fiber bundle 20 around the outer peripheral surface 15 of the annular portion 11B of the female bobbin member 11 while applying the tension α to the reinforcing fiber bundle 20 is performed. Specifically, referring to FIG. 13 and FIG. 14, for example, the reinforcing fiber bundle 20 is wound around the outer peripheral surface 15 of the annular portion 11 </ b> B of one female bobbin member 11 at least once, and then the adjacent female bobbin member 11. It is wound at least once around the outer peripheral surface 15 of the annular portion 11B. This step is preferably carried out at least twice. As a result, the reinforcing fiber bundle 20 has a fixed portion 21 wound around the outer peripheral surface 15 of the annular portion 11B of the female bobbin member 11, an extending portion 22 extending away from the outer peripheral surface 15, and an end portion. 23 are formed. When a plurality of reinforcing fiber bundles 20 are prepared, each reinforcing fiber bundle 20 may be wound around the outer peripheral surface 15 of the annular portion 11B of the female bobbin member 11.

なお、上記の工程において、たとえば強化繊維束２０を十分な張力αを負荷することなくメス型ボビン部材１１の環状部１１Ｂの外周面１５に巻き付けた場合には、固定部２１において強化繊維束２０の緩みが生じ、そのため外周面１５と固定部２１との間に隙間が生じる。また、この隙間には後に実施される工程にて樹脂３０が含浸硬化されて樹脂リッチ部が形成される。この樹脂リッチ部は負荷される外力Ｆにより塑性変形するため、発生すべき張力Ｔが低下する。そのため、上記のようにメス型ボビン部材１１の環状部１１Ｂの外周面１５と強化繊維束２０の固定部２１との隙間に樹脂リッチ部が形成された場合、継ぎ手補助部材１を採用することによる強度向上の効果が十分に得られない。そのため、固定部２１が外周面１５に沿って接触した状態で樹脂３０が含浸硬化されるように、十分な張力αを負荷することが好ましい。   In the above process, for example, when the reinforcing fiber bundle 20 is wound around the outer peripheral surface 15 of the annular portion 11B of the female bobbin member 11 without applying a sufficient tension α, the reinforcing fiber bundle 20 is fixed at the fixing portion 21. Loosening occurs, so that a gap is formed between the outer peripheral surface 15 and the fixed portion 21. In addition, the resin 30 is impregnated and cured in the gap in a process performed later to form a resin rich portion. Since the resin-rich portion is plastically deformed by the applied external force F, the tension T to be generated is reduced. Therefore, when the resin rich portion is formed in the gap between the outer peripheral surface 15 of the annular portion 11B of the female bobbin member 11 and the fixing portion 21 of the reinforcing fiber bundle 20 as described above, the joint auxiliary member 1 is employed. The effect of strength improvement cannot be obtained sufficiently. Therefore, it is preferable to apply a sufficient tension α so that the resin 30 is impregnated and cured in a state where the fixing portion 21 is in contact with the outer peripheral surface 15.

次に、強化繊維束２０に張力αを負荷しつつ、強化繊維束２０においてメス型ボビン部材１１の環状部１１Ｂに巻き付けられた部分である固定部２１に樹脂３０を含浸させ硬化させる工程が実施される。これにより、強化繊維束２０の固定部２１はメス型ボビン部材１１の環状部１１Ｂの外周面１５にて強固に固定される。樹脂３０としては、たとえばビニルエステル樹脂、エポキシ樹脂を用いることが可能であって、これら以外の樹脂を用いることもできる。   Next, the step of impregnating the resin 30 with the fixing portion 21 that is a portion of the reinforcing fiber bundle 20 that is wound around the annular portion 11B of the female bobbin member 11 while applying the tension α to the reinforcing fiber bundle 20 is performed. Is done. Thereby, the fixing portion 21 of the reinforcing fiber bundle 20 is firmly fixed on the outer peripheral surface 15 of the annular portion 11B of the female bobbin member 11. As the resin 30, for example, a vinyl ester resin or an epoxy resin can be used, and other resins can be used.

次に、図１５および図１６を参照して、固定部２１に含浸された樹脂が硬化した後、強化繊維束２０の延在部２２の一部である線分βに沿った領域にて強化繊維束２０を切断する工程が実施される。この場合、強化繊維束２０の端部２３は必要に応じて切除されもよい。その後、各々のメス型ボビン部材１１は円柱部材６１より取り外される。そして、これにオス型ボビン部材１２を組み合わせることにより、継ぎ手補助部材１が完成する。   Next, referring to FIG. 15 and FIG. 16, after the resin impregnated in the fixing portion 21 is cured, the resin is reinforced in a region along the line segment β which is a part of the extending portion 22 of the reinforcing fiber bundle 20. A step of cutting the fiber bundle 20 is performed. In this case, the end portion 23 of the reinforcing fiber bundle 20 may be cut as necessary. Thereafter, each female bobbin member 11 is removed from the cylindrical member 61. And the joint auxiliary member 1 is completed by combining the male bobbin member 12 with this.

次に、実施の形態１に係る継ぎ手構造部材２の製造方法について、図１７〜２２に基づいて説明する。実施の形態１に係る継ぎ手構造部材２の製造方法では、まず複数枚の強化繊維クロス４１と、実施の形態１に係る継ぎ手補助部材１とを準備する工程が実施される。   Next, a method for manufacturing the joint structural member 2 according to Embodiment 1 will be described with reference to FIGS. In the method for manufacturing the joint structure member 2 according to the first embodiment, a step of preparing a plurality of reinforcing fiber cloths 41 and the joint auxiliary member 1 according to the first embodiment is first performed.

次に、複数枚の強化繊維クロス４１に、厚み方向に貫通する貫通穴を形成する工程が実施される。この貫通穴は継ぎ手補助部材１を挿入可能に形成される。   Next, a step of forming through holes penetrating in the thickness direction in the plurality of reinforcing fiber cloths 41 is performed. This through hole is formed so that the joint auxiliary member 1 can be inserted.

次に、貫通穴に継ぎ手補助部材１が挿入されるように、貫通穴が形成された複数枚の強化繊維クロス４１を積層する工程が実施される。図１７および図１８を参照して、この工程では、まず強化繊維束２０の一部が巻き付けられ、樹脂３０が含浸硬化されたメス型ボビン部材１１が、継ぎ手補助部材取付冶具６２に備えられた円柱状突起６３に挿入される。次に、図１９を参照して、上記の工程により強化繊維クロス４１に形成された貫通穴にメス型ボビン部材１１および強化繊維束２０の延在部２２が通るようにして、強化繊維クロス４１が継ぎ手補助部材取付冶具６２の上に配置される。次に、図２０を参照して、強化繊維クロス４１の上に一の延在部２２がメス型ボビン部材１１の環状部１１Ｂの外周面１５から離れて延在するように配置される。強化繊維クロス４１上に配置された一の延在部２２の上には、さらに強化繊維クロス４１が積層される。次に、図２１を参照して、他の延在部２２が一の延在部２２と同様に、積層された強化繊維クロス４１上にてメス型ボビン部材１１の環状部１１Ｂの外周面１５から離れて延在するように配置される。強化繊維クロス４１上に配置された他の延在部２２の上には、さらに強化繊維クロス４１が積層される。   Next, a step of laminating a plurality of reinforcing fiber cloths 41 each having a through hole is performed so that the joint auxiliary member 1 is inserted into the through hole. Referring to FIGS. 17 and 18, in this step, first, a part of reinforcing fiber bundle 20 is wound, and female bobbin member 11 impregnated and cured with resin 30 is provided in joint auxiliary member mounting jig 62. It is inserted into the cylindrical protrusion 63. Next, referring to FIG. 19, the reinforcing fiber cloth 41 is formed such that the female bobbin member 11 and the extending portion 22 of the reinforcing fiber bundle 20 pass through the through holes formed in the reinforcing fiber cloth 41 by the above-described process.

Arranged so as to extend away from. A reinforcing fiber cloth 41 is further laminated on the other extending portion 22 arranged on the reinforcing fiber cloth 41.

次に、図２２を参照して、最上層の強化繊維クロス４１が積層された後にオス型ボビン部材１２が円柱状突起６３に挿入される。円柱状突起６３に挿入されたオス型ボビン部材１２はメス型ボビン部材１１と組み合わせられ、ボビン部材１０が形成される。   Next, referring to FIG. 22, the male bobbin member 12 is inserted into the columnar protrusion 63 after the uppermost reinforcing fiber cloth 41 is laminated. The male bobbin member 12 inserted into the columnar protrusion 63 is combined with the female bobbin member 11 to form the bobbin member 10.

最後に、積層された強化繊維クロス４１に樹脂を含浸させ、硬化させる工程が実施される。この工程では、積層された強化繊維クロス４１および強化繊維クロス４１の層間に延在している強化繊維束２０の延在部２２の全体にわたり、樹脂が含浸され硬化される。樹脂を硬化する方法としては、たとえば真空圧樹脂含浸（Vacuum assisted Resin Transfer Molding）法などを用いることができる。この方法では、まず継ぎ手補助部材取付冶具６２に積層された強化繊維クロス４１、強化繊維クロス４１の層間に延在している強化繊維束２０の延在部２２および円柱状突起６３に挿入されたメス型ボビン部材１１とオス型ボビン部材１２の全体が真空バッグによりバギングされる。そして、積層された強化繊維クロス４１および強化繊維クロス４１の層間に延在している強化繊維束２０の延在部２２の全体に樹脂が注入され硬化されることにより繊維強化プラスチックが形成される。以上のプロセスにより、継ぎ手構造部材２が完成する。   Finally, a step of impregnating the cured reinforcing fiber cloth 41 with a resin and curing it is performed. In this step, the resin is impregnated and cured over the entire extending portion 22 of the reinforcing fiber bundle 20 extending between the laminated reinforcing fiber cloth 41 and the reinforcing fiber cloth 41. As a method for curing the resin, for example, vacuum assisted resin impregnation (Vacuum assisted Resin Transfer Molding) method or the like can be used. In this method, first, the reinforcing fiber cloth 41 laminated on the joint auxiliary member attaching jig 62, the extending portion 22 of the reinforcing fiber bundle 20 extending between the layers of the reinforcing fiber cloth 41, and the columnar protrusion 63 were inserted. The whole female bobbin member 11 and male bobbin member 12 are bagged by the vacuum bag. Then, resin is injected into the entire extending portion 22 of the reinforcing fiber bundle 20 extending between the laminated reinforcing fiber cloth 41 and the reinforcing fiber cloth 41, and a fiber reinforced plastic is formed by curing. . The joint structure member 2 is completed by the above process.

（実施の形態２）
以下、本発明の実施の形態２について説明する。実施の形態２に係る継ぎ手補助部材は、基本的には実施の形態１に係る継ぎ手補助部材と同様の構造を有している。しかし、実施の形態２に係る継ぎ手補助部材においては強化繊維束が複数の延在部を有し、かつ各々の延在部が異なった方向に延在しているという点において実施の形態１に係る継ぎ手補助部材とは異なっている。 (Embodiment 2)
The second embodiment of the present invention will be described below. The joint auxiliary member according to the second embodiment basically has the same structure as the joint auxiliary member according to the first embodiment. However, in the joint auxiliary member according to the second embodiment, the reinforcing fiber bundle has a plurality of extending portions, and the first embodiment is different from the first embodiment in that each extending portion extends in a different direction. It is different from the joint auxiliary member.

はじめに、図２３および図２４を参照して、実施の形態２に係る継ぎ手補助部材１の構造について説明する。実施の形態２に係る継ぎ手補助部材１はボビン部材１０と、ボビン部材１０を構成するメス型ボビン部材１１の環状部１１Ｂの外周面１５に巻き付けられた強化繊維束２０を備えている。強化繊維束２０は、メス型ボビン部材１１の環状部１１Ｂの外周面１５に巻き付けられ樹脂３０により含浸硬化された固定部２１と、メス型ボビン部材１１の環状部１１Ｂの外周面１５から離れるように延在した複数の延在部２２を含んでいる。ここで、一本の強化繊維束２０がメス型ボビン部材１１の環状部１１Ｂの外周面１５に巻き付けられる場合は、その両端が延在部２２となっていてもよい。また、複数本の強化繊維束２０がメス型ボビン部材１１の環状部１１Ｂの外周面１５に巻き付けられる場合は、それらの一端または両端が延在部２２となっていてもよい。   First, the structure of the joint auxiliary member 1 according to the second embodiment will be described with reference to FIGS. 23 and 24. The joint auxiliary member 1 according to the second embodiment includes a bobbin member 10 and a reinforcing fiber bundle 20 wound around the outer peripheral surface 15 of the annular portion 11B of the female bobbin member 11 constituting the bobbin member 10.

At least three female bobbin members 11 are prepared. Next, each prepared female bobbin member 11 is inserted into a columnar member 61 provided in the reinforcing fiber bundle attachment jig 60. Here, with reference to FIG. 25, the columnar member 61 is arranged in the reinforcing fiber bundle mounting jig 60 so that two straight lines L and L ′ passing through the axial center form an angle a. The angle a is preferably substantially equal to the angle formed by the external forces F and F ′ to be applied to the single female bobbin member 11 inserted into the cylindrical member 61. In the present embodiment, the angle a is 90 °.

次に、強化繊維束２０に張力αを負荷しつつ、各々のメス型ボビン部材１１の環状部１１Ｂの外周面１５に強化繊維束２０の一部を巻き付ける工程が実施される。これにより、強化繊維束２０には、メス型ボビン部材１１の環状部１１Ｂの外周面１５に巻き付けられた固定部２１と、外周面１５から離れるように延在する延在部２２と、端部２３とがそれぞれ形成される。次に、強化繊維束２０の固定部２１に樹脂３０を含浸させ硬化させる工程が実施される。次に、固定部２１に含浸された樹脂３０が硬化した後、強化繊維束２０の延在部２２の一部にて、強化繊維束２０を切断する工程が実施される。そして、各々のメス型ボビン部材１１は円柱部材６１より取り外される。これにオス型ボビン部材１２を組み合わせることにより、実施の形態２における継ぎ手構造部材１が完成する。   Next, a step of winding a part of the reinforcing fiber bundle 20 around the outer peripheral surface 15 of the annular portion 11B of each female bobbin member 11 is performed while applying the tension α to the reinforcing fiber bundle 20. As a result, the reinforcing fiber bundle 20 has a fixed portion 21 wound around the outer peripheral surface 15 of the annular portion 11B of the female bobbin member 11, an extending portion 22 extending away from the outer peripheral surface 15, and an end portion. 23 are formed.

Of the plurality of extending portions 22, one extending portion 22 and the other extending portion 22 extend in different directions. Further, each extending portion 22 can be extended in a direction opposite to the direction of each of the plurality of external forces F and F ′ loaded on one female bobbin member 11.

また、実施の形態４に係る可動柵７０がたとえば可動式駅ホーム柵などに用いられる場合には、可動柵７０を構成する扉パネル７１に外力が負荷されることが想定される。図２８を参照して、たとえば扉パネル７１が閉じた状態にてホームにいる乗客が扉パネル７１に寄り掛かることなどにより、扉パネル７１に荷重Ｇが負荷されることも想定される。この場合には、継ぎ手構造部材２とリニアガイド７２との連結部においても同様に荷重Ｇが負荷される。   Moreover, when the movable fence 70 which concerns on Embodiment 4 is used for a movable station platform fence etc., it is assumed that external force is loaded on the door panel 71 which comprises the movable fence 70, for example. Referring to FIG. 28, it is assumed that a load G is applied to door panel 71, for example, when a passenger at the platform leans against door panel 71 with door panel 71 closed. In this case, the load G is similarly applied to the connecting portion between the joint structure member 2 and the linear guide 72.

図２９を参照して、実施の形態２に係る可動柵７０に含まれる継ぎ手構造部材２は、繊維強化プラスチック部材４２と繊維強化プラスチック部材４２内に配置された複数の継ぎ手補助部材１を備えている。また、繊維強化プラスチック部材４２の内部には荷重Ｇの負荷される方向に沿った方向に強化繊維束２０の延在部２２が延在している。そのため、延在部２２において、荷重Ｇによる負荷を軽減するような張力を発生させることができる。これにより、継ぎ手構造部材２とリニアガイド７２との連結部に負荷される荷重Ｇによる負荷を効率的に軽減することが可能になる。結果として、可動柵７０を可動式駅ホーム柵などに用いる場合において、可動柵７０に負荷されるべき荷重Ｇに耐え得るための強度を付与することが容易になる
今回開示された実施の形態はすべての点で例示であって、制限的なものではないと考えられるべきである。本発明の範囲は上記した説明ではなくて特許請求の範囲によって示され、特許請求の範囲と均等の意味、および範囲内でのすべての変更が含まれることが意図される。 29, the joint structure member 2 included in the movable fence 70 according to the second embodiment includes a fiber reinforced plastic member 42 and a plurality of joint auxiliary members 1 disposed in the fiber reinforced plastic member 42. Yes. Further, the extending portion 22 of the reinforcing fiber bundle 20 extends in the direction along the direction in which the load G is applied inside the fiber reinforced plastic member 42. Therefore, tension that reduces the load due to the load G can be generated in the extending portion 22. As a result, it is possible to efficiently reduce the load caused by the load G applied to the connecting portion between the joint structure member 2 and the linear guide 72. As a result, when the movable fence 70 is used as a movable station platform fence or the like, it is easy to give strength to withstand the load G to be applied to the movable fence 70. The embodiment disclosed this time It should be considered as illustrative in all respects and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
