＜構造の概要＞
本発明に係る板材締結構造の実施形態を図１〜図４に従って説明する。 <Outline of structure>
An embodiment of a plate material fastening structure according to the present invention will be described with reference to FIGS.

なお、各図において、図中矢印ＦＲは車体前部方向を、矢印ＲＥは車体後方方向を、矢印ＵＰは車体上方方向を、矢印ＩＮは内側を、矢印ＯＵＴは外側を示す。   In each figure, the arrow FR indicates the front direction of the vehicle body, the arrow RE indicates the rear direction of the vehicle body, the arrow UP indicates the upward direction of the vehicle body, the arrow IN indicates the inner side, and the arrow OUT indicates the outer side.

図１には、本発明が適用された第１実施形態に係る板材締結構造を備えた車体フレーム１０が示されている。   FIG. 1 shows a vehicle body frame 10 having a plate material fastening structure according to a first embodiment to which the present invention is applied.

すなわち車体上下方向に延設されたＦＲＰ製のセンターピラー３０に、車体幅方向に設けられた同じくＦＲＰ製のアンダーリンフォース３２が締結部分１１で接合され、車体フレーム１０を構成している。このとき、閉断面で中空の略角パイプ構造をしたセンターピラー３０の車体幅方向内側面に対して、アンダーリンフォース３２の車体幅方向端部が車体上下方向に立ち上がり、両者に設けられた貫通口を継手で締結することで締結部分１１を構成している。   In other words, the FRP center pillar 30 extending in the vertical direction of the vehicle body is joined to the underlink force 32 made of the same FRP provided in the vehicle body width direction at the fastening portion 11 to constitute the vehicle body frame 10. At this time, with respect to the inner side surface of the center pillar 30 in the vehicle width direction of the center pillar 30 having a hollow cross section with a closed cross section, the end portion in the vehicle width direction of the under reinforcement 32 rises in the vertical direction of the vehicle body. The fastening portion 11 is configured by fastening the mouth with a joint.

図２には、図１に示す締結構造のＡ−Ａ断面が示されている。   FIG. 2 shows an AA cross section of the fastening structure shown in FIG.

図２に示すように、センターピラー３０とアンダーリンフォース３２との締結部分１１において、略角パイプ形状をしたセンターピラー３０の車体幅方向内側部分の板材３０Ｂに設けられた貫通口３０Ａと、センターピラー３０の車体幅方向内側面に沿うように車体上下方向に立ち上がったアンダーリンフォース３２の板材３２Ｂに設けられた貫通口３２Ａとを、継手１２で締結している。   As shown in FIG. 2, in the fastening portion 11 between the center pillar 30 and the under reinforcement 32, a through-hole 30 </ b> A provided in a plate member 30 </ b> B in the vehicle body width direction inner portion of the center pillar 30 having a substantially square pipe shape, A joint 12 is fastened to a through-hole 32A provided in a plate member 32B of an under reinforcement 32 that rises in the vertical direction of the vehicle body along the inner surface of the pillar 30 in the vehicle width direction.

継手１２は、ゴムのような弾性部材で形成され、車体幅方向内側からアンダーリンフォース３２（板材３２Ｂ）を支持する第１のフランジ１４と、アンダーリンフォース３２側から貫通口３２Ａ、３０Ａを貫通するように挿入されたボデー部１６と、センターピラー３０の内部でボデー部１６が拡張し、内部からセンターピラー３０の板材３０Ｂを支持する第２のフランジ１８と、で構成されている。   The joint 12 is formed of an elastic member such as rubber, and penetrates the first flange 14 that supports the under reinforcement 32 (plate material 32B) from the inner side in the vehicle body width direction and the through holes 32A and 30A from the under reinforcement 32 side. The body portion 16 is inserted into the center pillar 30, and the body portion 16 extends inside the center pillar 30, and the second flange 18 supports the plate 30B of the center pillar 30 from the inside.

図３（Ａ）、図３（Ｂ）には、図２に示す締結構造に用いられる継手の構造および締結の工程が示されている。   FIGS. 3A and 3B show the structure of a joint used in the fastening structure shown in FIG. 2 and the fastening process.

図３（Ａ）に示すように、継手１２のボデー部１６は、センターピラー３０に設けられた貫通口３０Ａと、アンダーリンフォース３２に設けられた貫通口３２Ａとを貫通するように、アンダーリンフォース３２側（車体幅方向内側）から挿入される。   As shown in FIG. 3 (A), the body portion 16 of the joint 12 passes through the through hole 30 </ b> A provided in the center pillar 30 and the through hole 32 </ b> A provided in the under link force 32. Inserted from the force 32 side (inner side in the vehicle body width direction).

第１のフランジ１４がアンダーリンフォース３２の板材３２Ｂに車体幅方向内側から当接するまでボデー部１６が貫通口３２Ａ、３０Ａに挿入された状態で、開口部２０より空気、接着剤などの流体が注入される。   In the state where the body portion 16 is inserted into the through holes 32A and 30A until the first flange 14 comes into contact with the plate member 32B of the under reinforcement 32 from the inner side in the vehicle body width, fluid such as air and adhesive is passed through the opening 20. Injected.

図３（Ｂ）に示すように、注入された流体５０はバルブ部２２を経由してボデー部１６内に充填される。ボデー部１６をも含めた継手１２は弾性素材で形成されており、注入された流体５０は継手１２の内部より矢印５２のように継手１２を加圧する。   As shown in FIG. 3B, the injected fluid 50 is filled into the body portion 16 via the valve portion 22. The joint 12 including the body portion 16 is formed of an elastic material, and the injected fluid 50 pressurizes the joint 12 as indicated by an arrow 52 from the inside of the joint 12.

内部からの圧力により膨張する継手１２は、貫通口３２Ａ、３０Ａへの挿入部分においてはボデー部１６が拡大して貫通口３２Ａ、３０Ａの内壁に圧接し、貫通口３０Ａより板材３０Ｂの内部に突出したボデー部１６の先端部分は更に拡大して第２のフランジ１８を形成する。   In the joint 12 that expands due to the pressure from the inside, the body portion 16 expands at the insertion portion to the through holes 32A and 30A, presses against the inner walls of the through holes 32A and 30A, and protrudes into the plate member 30B from the through hole 30A. The front end portion of the body portion 16 is further enlarged to form the second flange 18.

継手１２は第１のフランジ１４と第２のフランジ１８とで、車体幅方向両側から板材３２Ｂ、３０Ｂを保持し、また第１のフランジ１４、第２のフランジ１８ともに矢印５２に示す内部からの圧力で膨張するため、車体幅方向両側から板材３２Ｂ、３０Ｂを加圧し、締結する。   The joint 12 includes the first flange 14 and the second flange 18, and holds the plate materials 32 </ b> B and 30 </ b> B from both sides in the vehicle body width direction. Both the first flange 14 and the second flange 18 are from the inside indicated by the arrow 52. In order to expand by pressure, the plate members 32B and 30B are pressurized from both sides in the vehicle body width direction and fastened.

バルブ部２２はボデー部１６と同じ弾性を持つ素材で形成されたチューブ形状の部材であり、図３（Ａ）に示すようにフランジ１４の裏面からボデー部１６の途中まで延設されている。   The valve portion 22 is a tube-shaped member made of a material having the same elasticity as that of the body portion 16, and extends from the back surface of the flange 14 to the middle of the body portion 16 as shown in FIG.

バルブ部２２は流体５０がボデー部１６内に外部から注入される際には抵抗とならず、且つボデー部１６内部の圧力が高くなれば径方向に潰れるので、ボデー部１６内部から外部への流体５０の流出を阻止する。これにより、一旦注入された流体５０はボデー部１６内部に留まり、継手１２を内部から加圧し続けることになり、膨張・拡大した第１のフランジ１４および第２のフランジ１８の形状が維持される。   The valve portion 22 does not become a resistance when the fluid 50 is injected into the body portion 16 from the outside, and collapses in the radial direction when the pressure inside the body portion 16 increases. The outflow of the fluid 50 is prevented. As a result, the fluid 50 once injected remains in the body portion 16 and continues to pressurize the joint 12 from the inside, so that the shapes of the first flange 14 and the second flange 18 expanded and expanded are maintained. .

＜作用効果＞
次に本発明の第１実施形態の作用および効果について説明する。 <Effect>
Next, the operation and effect of the first embodiment of the present invention will be described.

図２および図３（Ｂ）に示すように、継手１２は締結される板材３０Ｂ、３２Ｂを一方向から締結することができる。すなわち、中空パイプ形状のセンターピラー３０のように工具が入らない箇所であっても、予め受けナット等を設けずに、外側（この場合は車体幅方向内側）から開口部２０に流体５０を注入して締結作業を行うことができる。   As shown in FIGS. 2 and 3B, the joint 12 can fasten the plate members 30B and 32B to be fastened from one direction. That is, the fluid 50 is injected into the opening 20 from the outside (in this case, the inside in the vehicle width direction) without providing a receiving nut or the like in advance even in a place where a tool does not enter, such as the hollow pipe-shaped center pillar 30. Thus, the fastening work can be performed.

また継手１２はゴムなどの弾性を備えた素材で形成されているため、板材３０Ｂ、３２Ｂの板厚、あるいは貫通口３０Ａ、３２Ａの開口径が異なっている場合であっても、素材の弾性でこれを吸収し、柔軟に締結を行うことが可能となる。   Further, since the joint 12 is formed of a material having elasticity such as rubber, even if the plate thickness of the plate materials 30B and 32B or the opening diameters of the through holes 30A and 32A are different, the elasticity of the material is sufficient. This can be absorbed and the fastening can be performed flexibly.

さらに、弾性のある素材で形成された継手１２の第１のフランジ１４、第２のフランジ１８、および貫通口３０Ａ、３２Ａ内のボデー部１６により板材３０Ｂ、３２Ｂを締結するので、板材３０Ｂ、３２Ｂへ過大な締め付けトルクがかかる事態を回避できる。これにより板材３０Ｂ、３２ＢがＦＲＰなどのような樹脂であっても、荷重によるクリープなど塑性変形の発生を防ぐことができる。   Further, since the plate members 30B and 32B are fastened by the first flange 14 and the second flange 18 of the joint 12 formed of an elastic material and the body portion 16 in the through holes 30A and 32A, the plate members 30B and 32B are fastened. The situation where excessive tightening torque is applied can be avoided. Thereby, even if the plate members 30B and 32B are resin such as FRP, it is possible to prevent the occurrence of plastic deformation such as creep due to a load.

また、継手１２が貫通口３０Ａ、３２Ａの内径・形状に応じて膨張・拡大するので、貫通口３０Ａ、３２Ａに対する封止性に優れ、従来のリベット止め等に比較して良好な止水性を得ることができる。   In addition, since the joint 12 expands and expands according to the inner diameter and shape of the through-holes 30A and 32A, it has excellent sealing performance with respect to the through-holes 30A and 32A, and provides better water-stopping performance than conventional riveting. be able to.

さらに、継手１２はゴム等の素材で形成されているため、リベット止め等の金属による締結構造に比較して耐腐食性に優れ、被締結材（板材３０Ｂ、３２Ｂ）が金属であった場合でも、被締結材との間で電食が発生しないので、被締結材の耐腐食性を高めることができる。   Further, since the joint 12 is formed of a material such as rubber, it has superior corrosion resistance compared to a metal fastening structure such as riveting, and even when the material to be fastened (plate members 30B and 32B) is a metal. Since no electrolytic corrosion occurs between the material to be fastened, the corrosion resistance of the material to be fastened can be improved.

また、流体５０に空気を用いた場合は、バルブ部２２を開放し、継手１２より流体５０を抜くことにより第２のフランジ１８が縮小あるいは消滅するので、必要に応じて締結された板材３０Ｂ、３２Ｂを取り外すことができる。流体５０に空気を用いた場合、工程に備え付けのエアーガン等を用いて締結作業を行えるので、専用の工具が不要となりコスト削減を行うことができる。   Further, when air is used as the fluid 50, the second flange 18 is reduced or eliminated by opening the valve portion 22 and removing the fluid 50 from the joint 12, so that the plate member 30B fastened as necessary, 32B can be removed. When air is used as the fluid 50, the fastening operation can be performed using an air gun or the like provided for the process, so that a dedicated tool is not necessary and cost can be reduced.

一方、流体５０に接着剤などの硬化剤を用いた場合は、継手１２の内部で硬化剤が硬化することにより、継手１２は内側から保持されるので貫通口３０Ａ、３２Ａの内壁および近傍の板材３０Ｂ、３２Ｂの表面を強固に締結することができる。この場合も工程に備え付けの接着ガン等を用いて締結作業を行えるので、専用の工具が不要となりコスト削減を行うことができる。   On the other hand, when a curing agent such as an adhesive is used for the fluid 50, the coupling 12 is held from the inside by curing the curing agent inside the coupling 12, so that the inner wall of the through holes 30A and 32A and the adjacent plate material The surfaces of 30B and 32B can be firmly fastened. Also in this case, since the fastening work can be performed using an adhesive gun or the like provided for the process, a dedicated tool is not required and the cost can be reduced.

Yes. The body portion 16 of the joint 13 is inserted into the through-holes 32A and 30A, and fluid such as air and adhesive is injected from the opening portion 20 with both end portions in the longitudinal direction protruding from the surfaces of the plate members 30B and 32B.

図４（Ｂ）に示すように、注入された流体５０はバルブ部２２を経由してボデー部１６内に充填される。ボデー部１６をも含めた継手１２は弾性素材で形成されており、注入された流体５０は継手１２の内部より矢印５２のように継手１２を加圧する。   As shown in FIG. 4B, the injected fluid 50 is filled into the body portion 16 via the valve portion 22. The joint 12 including the body portion 16 is formed of an elastic material, and the injected fluid 50 pressurizes the joint 12 as indicated by an arrow 52 from the inside of the joint 12.

内部からの圧力により膨張する継手１２は、貫通口３２Ａ、３０Ａへの挿入部分においてはボデー部１６が拡大して貫通口３２Ａ、３０Ａの内壁に圧接し、貫通口３２Ａから板材３０Ｂより挿入方向手前側に突出したボデー部１６の後端部分は、拡大して第１のフランジ１４を形成する。また貫通口３０Ａより板材３０Ｂの挿入方向奥側に突出したボデー部１６の先端部分は拡大して第２のフランジ１８を形成する。   In the joint 12 that expands due to the pressure from the inside, the body portion 16 expands at the insertion portion to the through holes 32A and 30A, presses against the inner wall of the through holes 32A and 30A, and is in front of the plate material 30B from the through hole 32A. The rear end portion of the body portion 16 protruding to the side is enlarged to form the first flange 14. Further, the distal end portion of the body portion 16 that protrudes from the through-hole 30 </ b> A to the back side in the insertion direction of the plate material 30 </ b> B is enlarged to form the second flange 18.

第１実施形態の継手１２と同様、継手１３は第１のフランジ１４と第２のフランジ１８とで、車体幅方向両側から板材３２Ｂ、３０Ｂを保持し、また第１のフランジ１４、第２のフランジ１８ともに矢印５２に示す内部からの圧力で膨張するため、車体幅方向両側から板材３２Ｂ、３０Ｂを加圧し、締結する。   Similar to the joint 12 of the first embodiment, the joint 13 includes the first flange 14 and the second flange 18, and holds the plate materials 32 </ b> B and 30 </ b> B from both sides in the vehicle body width direction, and the first flange 14 and the second flange 18. Since both the flange 18 expands with the pressure from the inside indicated by the arrow 52, the plate members 32B and 30B are pressurized from both sides in the vehicle body width direction and fastened.

バルブ部２２は流体５０がボデー部１６内に外部から注入される際には抵抗とならず、且つボデー部１６内部の圧力が高くなれば径方向に潰れるので、ボデー部１６内部から外部への流体５０の流出を阻止することで、一旦注入された流体５０はボデー部１６内部に留まり、継手１２を内部から加圧し続けることにより、膨張・拡大した第１のフランジ１４および第２のフランジ１８の形状が維持される点も第１実施形態と同様である。   The valve portion 22 does not become a resistance when the fluid 50 is injected into the body portion 16 from the outside, and collapses in the radial direction when the pressure inside the body portion 16 increases. By preventing the fluid 50 from flowing out, the once injected fluid 50 stays inside the body portion 16 and continues to pressurize the joint 12 from the inside, thereby expanding and expanding the first flange 14 and the second flange 18. The point that the shape is maintained is the same as in the first embodiment.

さらに本実施形態において、継手１３は流体５０の注入前の段階ではフランジが存在しないため、被締結部材（板材３０Ｂ、３２Ｂ）の厚さ変化に対して柔軟に対応可能であり、また例えば円筒形状の収納部材に収められた継手１３を、複数の締結箇所に対して連続して使用するなどの使用方法が可能となる。   Furthermore, in this embodiment, since the joint 13 has no flange before the fluid 50 is injected, the joint 13 can flexibly cope with a change in the thickness of the fastened members (plate members 30B and 32B). The joint 13 housed in the housing member can be used continuously for a plurality of fastening locations.

以上、実施形態を挙げて本発明の実施の形態を説明したが、これらの実施形態は一例であり、要旨を逸脱しない範囲内で種々変更して実施できる。また、本発明の権利範囲がこれらの実施形態に限定されず、本発明の要旨を逸脱しない範囲において種々なる態様で実施し得ることは言うまでもない。   The embodiments of the present invention have been described above with reference to the embodiments. However, these embodiments are merely examples, and various modifications can be made without departing from the scope of the invention. Further, it goes without saying that the scope of rights of the present invention is not limited to these embodiments and can be implemented in various modes without departing from the gist of the present invention.

すなわち、上記実施形態ではＦＲＰ製のセンターピラーとアンダーリンフォースとの締結部分を例としたが、これに限定せず貫通口が設けられた部材同士の締結構造であれば、本発明を応用することができる。また被締結部材の素材についても、金属あるいはその他の素材であっても本発明を適用することができる。   That is, in the said embodiment, although the fastening part of the center pillar made from FRP and an under reinforcement was taken as an example, if it is the fastening structure of the members provided with the through-hole without being limited to this, the present invention is applied. be able to. Further, the present invention can be applied to the material of the fastened member even if it is a metal or other material.

さらにバルブ部２２の先端は、図３（Ａ）に示すように貫通口３０Ａを通過しボデー部１６の先端近くに位置していれば、流体注入によるフランジ１４の厚み増加の影響を受けず、また十分な長さを備えていれば、ボデー部１６の内圧で確実に径方向に潰れることでより効果的に流体の漏出防止を行える。   Furthermore, if the tip of the valve portion 22 passes through the through-hole 30A and is positioned near the tip of the body portion 16 as shown in FIG. Moreover, if it is provided with a sufficient length, the fluid can be more effectively prevented from leaking by being reliably crushed in the radial direction by the internal pressure of the body portion 16.

あるいはバルブ部２２をボデー部１６と同様の弾性部材とする代わりに別途、開口部２０の内側または外側に種々の構造を備えた逆止弁を設け、ボデー部１６内部に充填された流体の漏出を防止する構造としてもよい。   Alternatively, instead of using the valve portion 22 as an elastic member similar to that of the body portion 16, a check valve having various structures is provided inside or outside the opening portion 20, so that the fluid filled in the body portion 16 is leaked. It is good also as a structure which prevents.
