Description

本発明は、フランジ付カラーを含む締結構造体に関する。   The present invention relates to a fastening structure including a flanged collar.

従来より、ＦＲＰプレートに形成した取付け穴にフランジ付カラーを挿入し、ＦＲＰプレートに対してボルトを用いて金属製の被締結部材を締結固定した、フランジ付カラーを含む締結構造体が提案されている（例えば、特許文献１参照）。フランジ付カラーの先端（フランジ部と反対側の端）は、ＦＲＰプレートの表面と面一に設定されている。   Conventionally, a fastening structure including a flanged collar has been proposed in which a flanged collar is inserted into a mounting hole formed in the FRP plate, and a metal fastening member is fastened and fixed to the FRP plate using a bolt. (For example, refer to Patent Document 1). The front end (end opposite to the flange portion) of the flanged collar is set flush with the surface of the FRP plate.

しかし、従来のフランジ付カラーを含む締結構造体にはつぎの問題点がある。   However, the conventional fastening structure including the flanged collar has the following problems.

ＦＲＰプレートの厚みを一定に製作することは困難である。そのため、フランジ付カラーの先端がＦＲＰプレートの表面と面一にならない場合がある。ＦＲＰプレートの厚みが厚くなってしまうと、フランジ付カラーの先端がＦＲＰプレートの取付け穴内に位置し、ボルトの締結力がカラーでなくＦＲＰプレートにかかってしまう。ボルト締結力がＦＲＰプレートにかかると、ＦＲＰプレートにクリープが生じて荷重抜けが生じてしまう。
特開２００４−２２５８０２号公報 It is difficult to manufacture the FRP plate with a constant thickness. Therefore, the front end of the flanged collar may not be flush with the surface of the FRP plate. When the thickness of the FRP plate is increased, the end of the flanged collar is positioned in the mounting hole of the FRP plate, and the fastening force of the bolt is applied to the FRP plate instead of the collar. When the bolt fastening force is applied to the FRP plate, creep occurs in the FRP plate and load loss occurs.
JP 2004-225802 A

本発明の目的は、樹脂製部材にクリープが生じることを従来に比べて抑制できる、フランジ付カラーを含む締結構造体を提供することにある。   The objective of this invention is providing the fastening structure containing the collar with a flange which can suppress that creep arises in resin-made members compared with the past.

上記目的を達成する本発明はつぎの通りである。
（１） 樹脂製部材に形成した取付け穴にフランジ付カラーを挿入し、前記樹脂製部材に対して被締結部材を、前記樹脂製部材と前記被締結部材との間にワッシャを配置した状態でボルトを用いて締結固定する、フランジ付カラーを含む締結構造体であって、
前記フランジ付カラーは、フランジ部と、該フランジ部から前記フランジ付カラーの軸方向に延びており延び方向先端が前記樹脂製部材から突出している軸部と、を備えており、
前記ワッシャは、前記樹脂製部材側の面に前記フランジ付カラーの軸部の延び方向先端が当接する座ぐり部を備えており、
前記樹脂製部材と前記ワッシャの前記樹脂製部材側の面のうち前記座ぐり部が形成されていない面部分との間に接着剤が配置されている、
フランジ付カラーを含む締結構造体。 The present invention for achieving the above object is as follows.
(1) In a state where a collar with a flange is inserted into an attachment hole formed in the resin member, a member to be fastened with respect to the resin member, and a washer is disposed between the resin member and the member to be fastened A fastening structure including a flanged collar that is fastened and fixed using a bolt,
The flanged collar includes a flange portion, and a shaft portion extending from the flange portion in the axial direction of the flanged collar and extending in the extending direction, and protruding from the resin member.
The washer includes a counterbore part that a front end of the shaft part of the collar with flange comes into contact with the surface on the resin member side,
An adhesive is disposed between the resin member and the surface portion of the washer where the counterbore portion is not formed, on the resin member side surface.
Fastening structure including flanged collar.

上記（１）のフランジ付カラーを含む締結構造体によれば、以下の効果を得ることができる。   According to the fastening structure including the flanged collar (1), the following effects can be obtained.

（ａ） フランジ付カラーの軸部の延び方向先端が樹脂製部材から突出しているため、ボルトの締結力はカラーにかかり、ボルトの締結力が樹脂製部材にかかることを抑制できる。そのため、樹脂製部材にクリープが生じることを抑制できる。 (A) Since the extension direction front-end | tip of the axial part of the collar part with a flange protrudes from a resin-made member, the fastening force of a volt | bolt is applied to a collar and it can suppress that the fastening force of a volt | bolt is applied to a resin-made member. Therefore, it is possible to suppress the occurrence of creep in the resin member.

（ｂ） （ｂ−１）樹脂製部材と被締結部材との間にワッシャが配置されており、フランジ付カラーの軸部の延び方向先端が樹脂製部材から突出してワッシャに当接しているため、フランジ付カラーの軸部の延び方向先端を被締結部材に直接当接させる場合に比べて、被締結部材を保持する面積を大にすることができる。したがって、被締結部材にボルト軸方向と直交する方向の力がかかったときに、被締結部材がワッシャに対して傾くことを抑制できる。
また、（ｂ−２）樹脂製部材とワッシャの樹脂製部材側の面のうち座ぐり部が形成されていない面部分との間に接着剤が配置されているため、被締結部材にボルト軸方向と直交する方向の力がかかり、その力がワッシャに伝わった場合であっても、ワッシャが樹脂製部材に対して傾くことを抑制できる。
上記（ｂ−１）、（ｂ−２）より、被締結部材にボルト軸方向と直交する方向の力がかかった場合であっても、被締結部材が樹脂製部材に対して傾くことを抑制できる。 (B) (b-1) Since the washer is disposed between the resin member and the member to be fastened, the distal end of the flanged collar portion in the extending direction protrudes from the resin member and is in contact with the washer. As compared with the case where the front end of the shaft portion of the flanged collar is brought into direct contact with the fastened member, the area for holding the fastened member can be increased. Therefore, when the force of the direction orthogonal to a volt | bolt axial direction is applied to a to-be-fastened member, it can suppress that a to-be-fastened member inclines with respect to a washer.
Moreover, since the adhesive is arrange | positioned between the surface parts in which the spot facing part is not formed among the surface made of the resin member and the resin member side of the washer, the bolt shaft is attached to the member to be fastened. Even when a force in a direction orthogonal to the direction is applied and the force is transmitted to the washer, the washer can be prevented from being inclined with respect to the resin member.
From the above (b-1) and (b-2), even when a force in a direction orthogonal to the bolt axis direction is applied to the fastened member, the fastened member is prevented from being inclined with respect to the resin member. it can.

（ｃ） 樹脂製部材とワッシャの樹脂製部材側の面のうち座ぐり部が形成されていない面部分との間に接着剤が配置されているため、樹脂製部材の厚みがばらついても、接着剤の厚みでばらつきを吸収することができる。 (C) Since the adhesive is disposed between the resin member and the surface portion of the washer where the counterbore portion is not formed, even if the thickness of the resin member varies, Variations can be absorbed by the thickness of the adhesive.

（ｄ） ワッシャの樹脂製部材側の面に座ぐり部が形成されているため、ワッシャの樹脂製部材側の面のうち座ぐり部が形成されていない面部分と座ぐり部の底面との間に段が存在する。そのため、ワッシャに座ぐり部が設けられていない場合に比べて、接着剤が、フランジ付カラーの軸部の延び方向先端と座ぐり部の底面との間およびネジ部に入り込みにくくなる。したがって、樹脂製部材とワッシャとの間に配置した接着剤がボルト締結力に影響を及ぼすことを抑制できる。 (D) Since the spot facing portion is formed on the surface of the washer on the resin member side, the surface portion of the face on the resin member side of the washer where the spot facing portion is not formed and the bottom surface of the spot facing portion There are steps in between. Therefore, compared with the case where the counterbore portion is not provided on the washer, the adhesive is less likely to enter between the front end of the shaft portion of the flanged collar and the bottom surface of the counterbore portion and the screw portion. Therefore, it can suppress that the adhesive agent arrange | positioned between resin-made members and a washer influences bolt fastening force.

In the fastening structure 10 according to the embodiment of the present invention, the following effects can be obtained.
(A) Since the extending direction tip 22a of the shaft portion 22 of the flanged collar 20 protrudes from the resin member 30, the fastening force of the bolt 60 is applied to the collar 20, and the fastening force of the bolt 60 is applied to the resin member 30. This can be suppressed. Therefore, it is possible to suppress the occurrence of creep in the resin member.

（ｂ） （ｂ−１）樹脂製部材３０と被締結部材５０との間にワッシャ４０が配置されており、フランジ付カラー２０の軸部２２の延び方向先端２２ａが樹脂製部材３０から突出してワッシャ４０に当接しているため、フランジ付カラー２０の軸部２２の延び方向先端２２ａを被締結部材５０に直接当接させる場合に比べて、被締結部材５０を保持する面積を大にすることができる。したがって、被締結部材５０にボルト軸方向と直交する方向の力がかかったとき、被締結部材５０がワッシャ４０に対して傾くことを抑制できる。
また、（ｂ−２）樹脂製部材３０とワッシャ４０の面部分４２との間に第１の接着剤７１が配置されているため、被締結部材５０にボルト軸方向と直交する方向の力がかかり、その力がワッシャ４０に伝わった場合であっても、ワッシャ４０が樹脂製部材３０に対して傾くことを抑制できる。
上記（ｂ−１）、（ｂ−２）より、被締結部材５０にボルト軸方向と直交する方向の力がかかった場合であっても、被締結部材５０が樹脂製部材３０に対して傾くことを抑制できる。 (B) (b-1) The washer 40 is disposed between the resin member 30 and the fastened member 50, and the distal end 22 a in the extending direction of the shaft portion 22 of the flanged collar 20 protrudes from the resin member 30. Since it is in contact with the washer 40, the area for holding the fastened member 50 is made larger than in the case where the front end 22a of the shaft portion 22 of the flanged collar 20 is brought into direct contact with the fastened member 50.

Therefore, when the force of the direction orthogonal to a volt | bolt axial direction is applied to the to-be-fastened member 50, it can suppress that the to-be-fastened member 50 inclines with respect to the washer 40. FIG.
Further, (b-2) since the first adhesive 71 is disposed between the resin member 30 and the surface portion 42 of the washer 40, the force in the direction orthogonal to the bolt axis direction is applied to the fastened member 50. Even when the force is transmitted to the washer 40, the washer 40 can be prevented from being inclined with respect to the resin member 30.
Even if it is a case where the force of the direction orthogonal to a volt | bolt axial direction is applied to the to-be-fastened member 50 from said (b-1) and (b-2), the to-be-fastened member 50 inclines with respect to the resin-made members 30. This can be suppressed.

（ｃ） 樹脂製部材３０とワッシャ４０の面部分４２との間に第１の接着剤７１が配置されているため、樹脂製部材３０の厚みがばらついても、第１の接着剤７１の厚みでばらつきを吸収することができる。 (C) Since the first adhesive 71 is disposed between the resin member 30 and the surface portion 42 of the washer 40, the thickness of the first adhesive 71 even if the thickness of the resin member 30 varies. Can absorb variations.

（ｄ） ワッシャ４０に座ぐり部４１が形成されているため、座ぐり部４１の底面４１ａとワッシャ４０の面部分４２との間に段４３が存在する。そのため、ワッシャ４０に座ぐり部４１が設けられていない場合に比べて（段４３がない場合に比べて）、第１の接着剤７１が、フランジ付カラー２０の軸部２２の延び方向先端２２ａと座ぐり部４１の底面４１ａとの間およびネジ部に入り込みにくくなる。したがって、第１の接着剤７１がボルト締結力に影響を及ぼすことを抑制できる。 (D) Since the counterbore portion 41 is formed on the washer 40, a step 43 exists between the bottom surface 41 a of the counterbore portion 41 and the surface portion 42 of the washer 40. Therefore, compared with the case where the counterbore portion 41 is not provided on the washer 40 (as compared to the case where the stepped portion 43 is not provided), the first adhesive 71 is applied to the distal end 22a of the shaft portion 22 of the flanged collar 20 in the extending direction. And the bottom face 41a of the counterbore part 41 and the screw part is difficult to enter. Accordingly, it is possible to suppress the first adhesive 71 from affecting the bolt fastening force.

（ｅ） フランジ付カラー２０の延び方向先端２２ａが樹脂製部材３０の第２の面３２から突出しているので、延び方向先端２２ａが第２の面３２から突出していない場合に比べて、フランジ付カラー２０を樹脂製部材３０の取付け穴３１に挿入した後、延び方向先端２２ａに異物が付着しているか否かを容易に判別できる。また、延び方向先端２２ａに異物が付着している場合であっても、該異物を、延び方向先端２２ａが第２の面３２から突出していない場合に比べて、容易に除去できる。 (E) Since the distal end 22a in the extending direction of the flanged collar 20 protrudes from the second surface 32 of the resin member 30, the flanged collar 20 has a flange as compared with the case where the extending end 22a does not protrude from the second surface 32. After the collar 20 is inserted into the mounting hole 31 of the resin member 30, it can be easily determined whether or not a foreign substance is attached to the extending direction tip 22a. Further, even when foreign matter is attached to the extending direction tip 22a, the foreign matter can be easily removed as compared with the case where the extending direction tip 22a does not protrude from the second surface 32.
