Abstract

<P>PROBLEM TO BE SOLVED: To provide a fastening structure having a flanged collar, which allows adhesive to be applied to the entire outer peripheral surface of a collar part when bonding and fixing the flanged collar onto a resin member. <P>SOLUTION: Besides forming a groove 23 in the outer peripheral surface 21c of a shaft part 21 in a flanged collar 20, adhesive 60 is disposed on the groove 23. In comparison with the case where no groove 23 is formed, therefore, the application of the adhesive 60 to the shaft part 21 increases a bonding area of the adhesive 60 and shaft part 21 to enhance bonding force of the adhesive 60 to the shaft part 21. When the flanged collar 20 in which the adhesive 60 is applied to the shaft part 21 in advance is fitted in a resin member 30, the adhesive 60 is prevented from being taken away to the inner peripheral surface 31a of a mounting hole 31 in comparison with the case where the shaft part 21 has no groove 23, so that the adhesive 60 is drawn into the depth of the mounting hole 31 by the flanged collar 20. <P>COPYRIGHT: (C)2008,JPO&INPIT

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、フランジ付カラーを接着固定したＦＲＰプレートに対してボルトを用いて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）。フランジ付カラーは、フランジ部のみでＦＲＰプレートに接着固定されている。   Conventionally, a fastening structure including a flanged collar has been proposed in which a fastened member is fastened and fixed to a FRP plate to which the flanged collar is bonded and fixed using a bolt (see, for example, Patent Document 1). The flanged collar is bonded and fixed to the FRP plate only at the flange portion.

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.

被締結部材にボルト軸直交方向の力がかかると、その力は、ボルトからフランジ付カラーに伝わりフランジ付カラーからＦＲＰプレートに伝わる。したがって、フランジ付カラーがＦＲＰプレートに対して動くこと（がたつくこと）を防止しフランジ付カラーからＦＲＰプレートに確実に力を伝えるために、フランジ付カラーのフランジ部だけでなくフランジ付カラーの軸部（筒部）にも接着剤を配置しておくことが望ましい。   When a force in the direction perpendicular to the bolt axis is applied to the fastened member, the force is transmitted from the bolt to the flanged collar and from the flanged collar to the FRP plate. Therefore, in order to prevent the flanged collar from moving (shaking) with respect to the FRP plate and to transmit the force from the flanged collar to the FRP plate reliably, not only the flange part of the flanged collar but also the shaft part of the flanged collar. It is desirable to arrange an adhesive also on the (cylinder part).

しかし、特許文献１に開示された締結構造体では、フランジ付カラーのフランジ部のみをＦＲＰプレートに接着しているため、フランジ付カラーの軸部に接着剤が配置されていない。   However, in the fastening structure disclosed in Patent Document 1, since only the flange portion of the flanged collar is bonded to the FRP plate, no adhesive is disposed on the shaft portion of the flanged collar.

フランジ部だけでなく軸部にも接着剤を配置するために、フランジ部だけでなく軸部にも接着剤を塗布したフランジ付カラーをＦＲＰプレートに挿入することも考えられるが、フランジ付カラーをＦＲＰプレートに挿入する際に、軸部に塗布した接着剤がＦＲＰプレートのカラー取付け孔の内周面に付着して持っていかれてしまい、フランジ付カラーで孔の奥まで接着剤を引きずり込むことが困難である。   In order to place adhesive on the shaft as well as on the flange, it is possible to insert a flanged collar coated with adhesive not only on the flange but also the shaft, into the FRP plate. When inserting into the FRP plate, the adhesive applied to the shaft is stuck to the inner peripheral surface of the collar mounting hole of the FRP plate, and the flanged collar can drag the adhesive to the back of the hole. Have difficulty.

また、上記対策として、フランジ部の分だけでなく軸部の分の接着剤をもフランジ部に塗布して、フランジ付カラーをＦＲＰプレートに取付ける（嵌め込む）ことも考えられるが、図５に示すように、軸部２ａとＦＲＰプレート３とのカラー半径方向隙間が狭いため、接着剤６の大部分は軸部２ａに行き届かずにフランジ部２ｂの外にはみ出してしまう。軸部２ａとＦＲＰプレート３とのカラー半径方向隙間を大にすることも考えられるが、単純に隙間を大にしても、フランジ付カラー２がＦＲＰプレート３のカラー取付け孔３ａに対して軸ズレを起こしてしまう。
したがって、軸部の外周面全体に接着剤を配置することが困難である。
特開２００４−２２５８０２号公報 In addition, as a countermeasure, it is possible to apply not only the flange portion but also the shaft portion adhesive to the flange portion and attach (fit) the flanged collar to the FRP plate. As shown, since the collar radial direction gap between the shaft portion 2a and the FRP plate 3 is narrow, most of the adhesive 6 does not reach the shaft portion 2a and protrudes outside the flange portion 2b. Although it is conceivable to increase the gap in the collar radial direction between the shaft portion 2a and the FRP plate 3, the flanged collar 2 is displaced from the collar mounting hole 3a of the FRP plate 3 even if the gap is simply increased. Will be caused.
Therefore, it is difficult to arrange the adhesive on the entire outer peripheral surface of the shaft portion.

本発明の目的は、樹脂製部材にフランジ付カラーを接着固定する場合に、軸部の外周面全体に接着剤を配置できる、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 arrange | position an adhesive agent to the whole outer peripheral surface of a shaft part, when fixing a flanged collar to a resin-made member.

上記目的を達成する本発明はつぎの通りである。
（１） 樹脂製部材の取付け孔にフランジ付カラーを嵌合してボルトを用いて被締結部材を締結固定してなる、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軸部とフランジ部を備えており、前記フランジ付カラーの軸部の外周面に溝を形成するとともに該溝に接着剤を配置した、フランジ付カラーを含む締結構造体。
（２） 前記溝の断面形状は略Ｖ字状をなしており、該溝角度が鈍角に設定されている（１）記載の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) A fastening structure including a flanged collar, wherein a flanged collar is fitted into a mounting hole of a resin member and a fastening member is fastened and fixed using a bolt,
A fastening structure including a flanged collar, wherein the flanged collar includes a shaft portion and a flange portion, and a groove is formed on an outer peripheral surface of the shaft portion of the flanged collar and an adhesive is disposed in the groove.
(2) The fastening structure including the flanged collar according to (1), wherein the cross-sectional shape of the groove is substantially V-shaped, and the groove angle is set to an obtuse angle.

上記（１）のフランジ付カラーを含む締結構造体によれば、フランジ付カラーの軸部の外周面に溝を形成するとともに該溝に接着剤を配置しているため、軸部の外周面に接着剤を塗布した場合、溝が形成されていない場合に比べて、接着剤と軸部との接着面積が増加し接着剤の軸部への接着力が増加する。そのため、軸部の外周面に接着剤を予め塗布しておいたフランジ付カラーを樹脂製部材に嵌める際、軸部に溝が形成されていない場合に比べて、樹脂製部材の取付け孔の内周面に接着剤が持っていかれ難くなり、取付け孔の奥までフランジ付カラーで接着剤を引きずり込むことができる。したがって、従来に比べて、フランジ付カラーの軸部の外周面全体にムラなく接着剤を配置することができる。   According to the fastening structure including the flanged collar of (1) above, the groove is formed on the outer peripheral surface of the shaft portion of the flanged collar and the adhesive is disposed in the groove. When the adhesive is applied, the adhesive area between the adhesive and the shaft portion is increased and the adhesive force of the adhesive to the shaft portion is increased as compared with the case where no groove is formed. For this reason, when a flanged collar whose adhesive has been applied to the outer peripheral surface of the shaft portion is fitted to the resin member, the inner diameter of the mounting hole of the resin member is smaller than when no groove is formed in the shaft portion. It becomes difficult for the adhesive to be carried around the peripheral surface, and the adhesive can be dragged with a flanged collar to the back of the mounting hole. Therefore, compared with the past, an adhesive agent can be arrange | positioned uniformly in the outer peripheral surface of the axial part of a collar with a flange.

上記（２）のフランジ付カラーを含む締結構造体によれば、溝角度が鈍角に設定されているため、溝角度が鋭角に設定されている場合に比べて、溝深さが浅くなり、軸部に溝を形成した場合でも軸部の強度低下を抑えることができる。   According to the fastening structure including the flanged collar of (2) above, since the groove angle is set to an obtuse angle, the groove depth becomes shallower than when the groove angle is set to an acute angle, and the shaft Even when a groove is formed in the portion, a decrease in strength of the shaft portion can be suppressed.

以下に、図１〜図４を参照して、本発明実施例のフランジ付カラーを含む締結構造体を説明する。   Below, with reference to FIGS. 1-4, the fastening structure containing the collar with a flange of this invention Example is demonstrated.

本発明実施例のフランジ付カラーを含む締結構造体１０は、図１に示すように、樹脂製部材３０の取付け孔３１にフランジ付カラー２０を嵌合（挿入、圧入、取付けを含む）してボルト５０を用いて被締結部材４０を締結固定してなる締結構造体である。締結構造体１０は、フランジ付カラー２０と、樹脂製部材３０と、金属製の被締結部材４０と、ボルト５０と、フランジ付カラー２０を樹脂製部材３０に接着固定する接着剤６０と、を有する。   As shown in FIG. 1, the fastening structure 10 including the flanged collar according to the embodiment of the present invention is configured by fitting the flanged collar 20 into the mounting hole 31 of the resin member 30 (including insertion, press-fitting, and mounting). This is a fastening structure in which the fastened member 40 is fastened and fixed using bolts 50. The fastening structure 10 includes a flanged collar 20, a resin member 30, a metal fastened member 40, a bolt 50, and an adhesive 60 that bonds and fixes the flanged collar 20 to the resin member 30. Have.

フランジ付カラー２０は、金属製である。フランジ付カラー２０は、接着剤６０を用いて樹脂製部材３０に接着固定される。フランジ付カラー２０は、軸部２１と、フランジ部２２と、を備える。   The flanged collar 20 is made of metal. The flanged collar 20 is bonded and fixed to the resin member 30 using an adhesive 60. The flanged collar 20 includes a shaft portion 21 and a flange portion 22.

軸部２１は、フランジ付カラー２０の軸方向でフランジ部２２が設けられていない部分である。軸部２１は、ボルト５０が挿入されるボルト挿入用穴２１ａを備える。ボルト挿入用穴２１ａは、フランジ付カラー２０をカラー軸方向に貫通する貫通孔であってもよく、袋穴であってもよい（図示例では袋穴である場合を示している）。軸部２１の内周面に、ボルト５０がねじ込まれる雌ネジ２１ｂが形成されている。ボルト５０がねじ込まれる雌ネジ２１ｂが形成されているため、フランジ付カラー２０は、フランジ付カラーナット２０といってもよい。   The shaft portion 21 is a portion where the flange portion 22 is not provided in the axial direction of the flanged collar 20. The shaft portion 21 includes a bolt insertion hole 21a into which the bolt 50 is inserted. The bolt insertion hole 21a may be a through-hole penetrating the flanged collar 20 in the collar axis direction, or may be a bag hole (in the illustrated example, the case is a bag hole). A female screw 21 b into which the bolt 50 is screwed is formed on the inner peripheral surface of the shaft portion 21. Since the female screw 21b into which the bolt 50 is screwed is formed, the flanged collar 20 may be referred to as a flanged collar nut 20.

軸部２１の、外周面２１ｃには、溝２３が形成されている。溝２３は、（ｉ）図２に示すように、カラー軸方向と直交する方向に軸部２１の全周にわたって形成されていてもよく、（ｉｉ）図４に示すように、らせん状に形成されていてもよく、（ｉｉｉ）図示略のクロス（Ｘ）状に形成されていてもよく、（ｉｖ）その他の形状に形成されていてもよい。なお、溝２３がらせん状またはクロス状に形成されている場合（上記（ｉｉ），（ｉｉｉ）の場合）には、接着剤６０が軸部２１の外周面２１ｃと取付け孔３１の内周面３１ａとの間Ａから被締結部材４０側に流出することを防止するために、溝２３の被締結部材４０側端が閉塞端になっていることが望ましい。以下、本発明実施例では、溝２３が、図２に示すように、カラー軸方向と直交する方向に軸部２１の全周にわたって形成されている場合（上記（ｉ）の場合）を例にとって説明する。   A groove 23 is formed on the outer peripheral surface 21 c of the shaft portion 21. The groove 23 may be (i) formed over the entire circumference of the shaft portion 21 in a direction orthogonal to the collar axis direction as shown in FIG. 2, and (ii) formed in a spiral shape as shown in FIG. (Iii) It may be formed in a cross (X) shape not shown, or (iv) may be formed in other shapes. When the groove 23 is formed in a spiral shape or a cross shape (in the case of (ii) and (iii) above), the adhesive 60 is applied to the outer peripheral surface 21c of the shaft portion 21 and the inner peripheral surface of the mounting hole 31. In order to prevent the end of the groove 23 from flowing from A to the fastened member 40 side, it is preferable that the fastened member 40 side end of the groove 23 is a closed end. Hereinafter, in the embodiment of the present invention, the case where the groove 23 is formed over the entire circumference of the shaft portion 21 in the direction orthogonal to the collar axis direction as shown in FIG. 2 (in the case of (i) above) is taken as an example. explain.

溝２３は、軸部２１において、カラー軸方向に所定間隔ごとに(間隔をおいて)設けられている。溝２３の横断面形状は、図３に示すように、Ｖ字形状またはほぼＶ字形状であり、溝角度ａが鈍角に設定されている。溝２３の断面形状において、溝２３の最奥部からカラー軸方向一側の開口縁までの距離ｂと、溝２３の最奥部からカラー軸方向他側の開口縁までの距離ｃとは、等しい。溝２３の深さは、軸部２１の強度に影響がないかまたはあっても無視できる程度に、設定されている。   The grooves 23 are provided in the shaft portion 21 at predetermined intervals (with an interval) in the collar axis direction. As shown in FIG. 3, the cross-sectional shape of the groove 23 is V-shaped or substantially V-shaped, and the groove angle a is set to an obtuse angle. In the cross-sectional shape of the groove 23, the distance b from the innermost part of the groove 23 to the opening edge on one side in the color axis direction and the distance c from the innermost part of the groove 23 to the opening edge on the other side in the color axis direction are: equal. The depth of the groove 23 is set to such an extent that the strength of the shaft portion 21 is not affected or can be ignored.

樹脂製部材３０は、たとえばＣＦＲＰなどのＦＲＰ（繊維強化樹脂）製である。樹脂製部材３０は、１枚構成であってもよく、複数枚を樹脂製部材３０の厚み方向（カラー軸方向と同方向）に重ねた複数枚構成であってもよい。なお、図示例では１枚構成である場合を示している。   The resin member 30 is made of, for example, FRP (fiber reinforced resin) such as CFRP. The resin member 30 may have a single-sheet configuration, or may have a multiple-sheet configuration in which a plurality of layers are stacked in the thickness direction of the resin member 30 (the same direction as the color axis direction). In the illustrated example, the case of a single sheet configuration is shown.

樹脂製部材３０は、軸部２１が嵌め込まれる取付け孔３１を備える。樹脂製部材３０は、さらに、フランジ部２２を収容する図示略の座ぐり部を備えていてもよい。   The resin member 30 includes a mounting hole 31 into which the shaft portion 21 is fitted. The resin member 30 may further include a counterbore portion (not shown) that accommodates the flange portion 22.

軸部２１の、フランジ部２２と反対側の端面２１ｄは、樹脂製部材３０の端面３０ａと、面一または略面一になっている。そのため、被締結部材４０と軸部２１の端面２１ｄとを面接触させることができ、ボルト５０の軸力による樹脂製部材３０のクリープによる締結力抜けは生じない。   An end surface 21d of the shaft portion 21 opposite to the flange portion 22 is flush with or substantially flush with the end surface 30a of the resin member 30. Therefore, the to-be-fastened member 40 and the end surface 21d of the shaft portion 21 can be brought into surface contact with each other, and a fastening force drop due to creep of the resin member 30 due to the axial force of the bolt 50 does not occur.

被締結部材４０と樹脂製部材３０は、ワッシャ５１（またはボルト５０の頭部裏面）とフランジ部２２とにより、ボルト軸方向に挟まれる。   The fastened member 40 and the resin member 30 are sandwiched between the washer 51 (or the back surface of the head of the bolt 50) and the flange portion 22 in the bolt axial direction.

接着剤６０は、軸部２１の外周面２１ｃと取付け孔３１の内周面３１ａとの間Ａと、フランジ部２２のうち軸部２１からカラー半径方向外側に延びている部分の裏面（下面）２２ａと樹脂製部材３０の端面３０ｂとの間Ｂに、配置される。接着剤６０は、接着剤６０を軸部２１の外周面２１ｃ（溝２３を含む）とフランジ部２２の裏面２２ａに塗布したフランジ付カラー２０を樹脂製部材３０の取付け孔３１に嵌めることで、間Ａ、Ｂに配置される。なお、接着剤６０を軸部２１の外周面２１ｃのみに塗布した場合であっても、フランジ付カラー２０を樹脂製部材３０の取付け孔３１に嵌めるときに、接着剤６０の一部が樹脂製部材３０の取付け孔３１の開口により掻き落とされて間Ｂに配置されるため、フランジ付カラー２０に接着剤６０を予め塗布しておく部位は軸部２１の外周面２１ｃのみであってもよい。   The adhesive 60 is formed between the outer peripheral surface 21c of the shaft portion 21 and the inner peripheral surface 31a of the mounting hole 31, and the back surface (lower surface) of the portion of the flange portion 22 that extends outward from the shaft portion 21 in the collar radial direction. It arrange | positions in B between 22a and the end surface 30b of the resin-made members 30. FIG. The adhesive 60 is obtained by fitting the flanged collar 20 in which the adhesive 60 is applied to the outer peripheral surface 21c (including the groove 23) of the shaft portion 21 and the back surface 22a of the flange portion 22 into the mounting hole 31 of the resin member 30. Arranged between A and B. Even when the adhesive 60 is applied only to the outer peripheral surface 21c of the shaft portion 21, when the flanged collar 20 is fitted into the mounting hole 31 of the resin member 30, a part of the adhesive 60 is made of resin. Since it is scraped off by the opening of the mounting hole 31 of the member 30 and is disposed in the middle B, the part where the adhesive 60 is previously applied to the flanged collar 20 may be only the outer peripheral surface 21c of the shaft portion 21. .

ここで、フランジ付カラー２０を含む締結構造体１０の締結方法を説明する。   Here, a fastening method of the fastening structure 10 including the flanged collar 20 will be described.

フランジ付カラー２０を含む締結構造体１０の締結方法は、（ａ）軸部２１の外周面２１ｃのみに、または軸部２１の外周面２１ｃとフランジ部２２の裏面２２ａの両方に、接着剤６０を全周にわたって塗布する工程と、（ｂ）接着剤６０が塗布されたフランジ付カラー２０を、取付け孔３１に、軸部２１の端面２１ｄが樹脂製部材３０の端面３０ａと面一または略面一になるまで嵌め込み、接着剤６０を間Ａ、Ｂに配置する工程と、（ｃ）接着剤６０が硬化した後に、被締結部材４０の一面４０ａが軸部２１の端面２１ｄに接触するようにして被締結部材４０の他側（フランジ付カラー２０と反対側）から、ボルト５０を、被締結部材４０のボルト挿通孔４１を挿通させて雌ネジ２１ｂにねじ込む工程と、を有する。   The fastening structure 10 including the flanged collar 20 includes: (a) the adhesive 60 only on the outer peripheral surface 21c of the shaft portion 21 or on both the outer peripheral surface 21c of the shaft portion 21 and the back surface 22a of the flange portion 22; And (b) the flanged collar 20 to which the adhesive 60 is applied, the mounting hole 31, and the end surface 21d of the shaft portion 21 is flush with or substantially flush with the end surface 30a of the resin member 30. (C) After the adhesive 60 is cured, the one surface 40a of the fastened member 40 is brought into contact with the end surface 21d of the shaft portion 21. The bolt 50 is inserted into the female screw 21b through the bolt insertion hole 41 of the fastened member 40 from the other side of the fastened member 40 (the side opposite to the flanged collar 20).

つぎに、本発明実施例の作用を説明する。
本発明実施例では、フランジ付カラー２０の軸部２１の外周面２１ｃに溝２３を形成するとともに該溝２３に接着剤６０を配置しているため、軸部２１の外周面２１ｃに接着剤６０を塗布した場合、溝２３が形成されていない場合に比べて、接着剤６０と軸部２１との接着面積が増加し接着剤６０の軸部２１への接着力が増加する。そのため、軸部２１の外周面２１ｃに接着剤６０を予め塗布しておいたフランジ付カラー２０を樹脂製部材３０に嵌める際、軸部２１に溝２３が形成されていない場合に比べて、樹脂製部材３０の取付け孔３１の内周面３１ａに接着剤６０が持っていかれ難くなり、取付け孔３１の奥までフランジ付カラー２０で接着剤６０を引きずり込むことができる。したがって、従来に比べて、フランジ付カラー２０の軸部２１の外周面２１ｃ全体にムラなく接着剤６０を配置することができる。 Next, the operation of the embodiment of the present invention will be described.
In the embodiment of the present invention, the groove 23 is formed in the outer peripheral surface 21c of the shaft portion 21 of the flanged collar 20 and the adhesive 60 is disposed in the groove 23. Therefore, the adhesive 60 is applied to the outer peripheral surface 21c of the shaft portion 21. Is applied, the adhesive area between the adhesive 60 and the shaft portion 21 is increased and the adhesive force of the adhesive 60 to the shaft portion 21 is increased as compared with the case where the groove 23 is not formed. For this reason, when the flanged collar 20 in which the adhesive 60 is applied in advance to the outer peripheral surface 21c of the shaft portion 21 is fitted to the resin member 30, the resin is compared with the case where the groove 23 is not formed in the shaft portion 21. It becomes difficult for the adhesive 60 to be held on the inner peripheral surface 31 a of the mounting hole 31 of the manufacturing member 30, and the adhesive 60 can be dragged by the flanged collar 20 to the back of the mounting hole 31. Therefore, the adhesive 60 can be disposed evenly over the entire outer peripheral surface 21c of the shaft portion 21 of the flanged collar 20 as compared with the conventional case.

溝２３の角度ａが鈍角に設定されているため、溝２３の角度が鋭角に設定されている場合に比べて、溝２３の深さが浅くなり、軸部２１に溝２３を形成した場合でも軸部２１の強度低下を抑えることができる。   Since the angle a of the groove 23 is set to an obtuse angle, the depth of the groove 23 becomes shallower than when the angle of the groove 23 is set to an acute angle, and the groove 23 is formed in the shaft portion 21. The strength reduction of the shaft portion 21 can be suppressed.

溝２３の角度ａが鈍角に設定されているため、溝２３の角度が鋭角に設定されている場合に比べて、溝２３の深さが浅くなり、溝２３を形成したことによる接着面積増加が軸部２１と樹脂製部材３０との接着力増加に効きやすくなる。   Since the angle a of the groove 23 is set to an obtuse angle, the depth of the groove 23 becomes shallower than when the angle of the groove 23 is set to an acute angle, and an increase in the adhesion area due to the formation of the groove 23 is increased. It becomes easy to increase the adhesive force between the shaft portion 21 and the resin member 30.

溝２３は、軸部２１部分においてカラー軸方向に所定間隔ごとに(間隔をおいて)設けられているため、溝２３を設けた場合でも軸部２１で取付け孔３１の内周面３１ａを傷つけることを防止できる。 Since the grooves 23 are provided at predetermined intervals (intervals) in the collar axis direction in the shaft 21 portion, even when the grooves 23 are provided, the shaft 21 damages the inner peripheral surface 31a of the mounting hole 31. Can be prevented.
