【発明の属する技術分野】
この発明は人工衛星構体などに用いられる継手具及び継手具とパネルとを接合する方法に関するものである。
【０００２】
【従来の技術】
コ字形状の単一部品として製造し、これをパネルに取付け、両者を接着剤によって接着して結合する際、継手具内部の厚さ寸法を、パネルの厚さ寸法よりも大きく設計しておき、継手具をパネルに差し込むようにして接着するが、接着層に位置決めピンを貫通させてパネルと継手具を位置決めした後、接着剤で接合することが開示されている（例えば、特許文献１参照。）。
【０００３】
【特許文献１】
特公平５―２３５８７号公報（第３―４頁、第２図）
【０００４】
【発明が解決しようとする課題】
以上の従来の継手具とパネルの接着接合方法によれば、パネルおよび継手具の製造公差によって、パネルと継手具の隙間寸法にばらつきが生じ、このため、安定した接着層の厚さが得られない。また、継手がコ字形状の剛性体であるため、接着面に圧力をかけることができない。従って、安定した接着強度が得られないという問題点があった。
【０００５】
また、安定した接着強度が得られない場合、強度設計において安全余裕を大きく見積らねばならず、結果として、より大きな接着強度を得るため、継手具の接着面積を大きく設計することになり、重量の増加を招くという問題点もある。
【０００６】
また、継手具をパネルに差し込むので、パネルに予め塗布しておいた接着剤が継手具にかき取られ、かき取られた接着剤が接着部以外に侵入してしまうという問題点もある。
【０００７】
この発明は、前記問題を解決するためになされたものであり、パネルおよび継手具の製造公差によらず、接着層の厚さが安定し、従って、安定した接着強度が得られ、かつ、パネルと継手具を接着する際に接着剤をかき取らない接合方法を提供することを目的とする。
【０００８】
【課題を解決するための手段】
第１の発明の継手具は、パネルの端部に結合されるコ字形状の継手具において、パネルの端部と上下面の一方の面に対向して設置されるＬ字形状の継手具と、パネルの上下面の他方の面に対向して設置されＬ字形状の継手具と別体に形成された板形状の継手具とから成り、Ｌ字形状の継手具と板形状の継手具でコ字形状を形成するように配置し、Ｌ字形状の継手具と板形状の継手具は嵌合されて互いに結合されているものである。
【０００９】
第２の発明の継手具とパネルの接着接合方法は、Ｌ字形状の継手具と板形状の継手具を、パネルの端部に結合する接合方法において、これらの継手具とパネル、ならびにこれらの継手具同士とを、その接着層に高精度の厚さ寸法を有するスペーサをはさみ込んで接着するものである。
【００１０】
【発明の実施の形態】
実施の形態１．
図１はこの発明の実施の形態１であり、１はサンドイッチパネル、２は表皮、３はコア材、４はＬ字形状の継手具、５ははめ込み接着部を有する板形状の継手具である。
【００１１】
図１において、サンドイッチパネル１は、コア材３の上下面に表皮２を有し、サンドイッチパネル１の端部及び上下面の三面を覆うように取り付けられた継手具で構成され、この継手具は端部と下面に対向して設置されるＬ字形状の継手具４とサンドイッチパネル１の上面に対向して設置され、Ｌ字形状の継手具と別体に形成されたはめ込み接着部を有する板形状の継手具５から構成されており、Ｌ字形状の継手具４と板形状の継手具５はサンドイッチパネル１との間を接着剤により接合して使用されるものである。
【００１２】
図２はこの発明の継手具の斜視図をに示し、６はねじ穴、７はＬ字形状の継手具４に設置された凸部嵌合部、８は板形状の継手具５に設置された凹部嵌合部であり、４、５は図１と同じものである。
【００１３】
図２に示すように、従来のコ字形状の継手具に相当する部分はねじ穴６を有するＬ字形状の継手具４と、これにはめ込み接着部を有する板形状の継手具５に分けて製造される。
【００１４】
Ｌ字形状の継手具４と板形状の継手具５でコ字形状を形成するように配置し、Ｌ字形状の継手具４と板形状の継手具５は嵌合されて互いに結合させて使用する。
【００１５】
Ｌ字形状の継手具４と板形状の継手具５は、Ｌ字形状の継手具４の凸部嵌合部７と板形状の継手具５の凹部嵌合部８により結合され、板形状の継手具５はサンドイッチパネル１の厚さ方向にＬ字形状の継手具４との間隔を自由に可変できる構造であり、サンドイッチパネル１の厚さに対応した所定の厚さに設置されて使用される。
【００１６】
また、Ｌ字形状の継手具４の凸部嵌合部７と板形状の継手具５の凹部嵌合部８により結合された板形状の継手具５はサンドイッチパネル１の表面上で横方向への移動に対しては、Ｌ字形状の継手具４の凸部嵌合部７と板形状の継手具５の凹部嵌合部８を嵌合させた後は横方向へは移動することができなくなるように一体化して剛性力が生ずる結合構造である。
【００１７】
なお、用途によっては、ねじ穴６が無いＬ字形状の継手具４にはめ込み接着部を有する板形状の継手具５とを使用する場合も良い。
【００１８】
図３は図１のＢ−Ｂ断面を示し、９ａは厚さ方向接着層、９ｂはたて接着層、１０はスペーサ、１１は継手具内部の厚さ寸法、１２はサンドイッチパネルの厚さ寸法、１３はサンドイッチパネルと継手具の隙間寸法、１４はＬ字型継手部内部の厚さ寸法であり、１〜５は図１同じ、６は図２と同じものである。
【００１９】
図３において、上下面に表皮２を有するサンドイッチパネル１の下面とＬ字形状の継手具４との間、および、サンドイッチパネル１の上面と板形状の継手具５との間を、接着層９ａにサンドイッチパネル１の厚さ方向にスペーサ１０をはさみ込んで、さらに、サンドイッチパネル１の端部とＬ字形状の継手具４との間隙に、上下横の三方向から充填された接着剤を硬化させる。
【００２０】
サンドイッチパネル１の厚さ方向の寸法は、Ｌ字形状の継手具４とサンドイッチパネル１と板形状の継手具５とを、それぞれの接着層９ａにサンドイッチパネル１の厚さ方向に所定の厚さ寸法で精度に加工されたスペーサ１０をはさみ込むようにして上下方向から加圧して接着層９ａに充填された接着剤を硬化させるため、サンドイッチパネル１の厚さ方向での寸法及び接着層９ａの厚さ寸法や接着層９ａの上下面の厚さ寸法のバランスが精度良く製造することができる。
【００２１】
ここで、スペーサ１０は、サンドイッチパネル１の厚さに対応して、所定の厚さ寸法で精度良く加工されたものであり、Ｌ字形状の継手具４及び板形状の継手具５の幅方向の長さに対応した長さを有する丸棒または、角材等を使用する。
【００２２】
ここで、丸棒を使用する場合は、径方向の寸法を精度良く管理して製作されたものを使用し、角材を場合、サンドイッチパネル１の厚さ方向の寸法に対応した高さ方向の寸法を精度良く管理して製作されたものを使用する。
【００２３】
また、スペーサ１０としては、球状のものを使用し、Ｌ字形状の継手具４及び板形状の継手具５の接着面積の範囲内全体に任意の配置で全体をカバーするように配置させて使用することも可能である。
【００２４】
Ｌ字形状の継手具４内部の厚み寸法１４はサンドイッチパネル厚み寸法１０より充分に大きいことも良い。
【００２５】
これにより、サンドイッチパネル１、Ｌ字形状の継手具４、板形状の継手具５の製造公差によらず、接着層９ａの厚さがスペーサ１０の厚さと同じになる。
【００２６】
なお、Ｌ字形状の継手具４は、サンドイッチパネル１の端部およびサンドイッチパネル１の上下面に形成された表皮２の下面接着層９ａを介在させて置くようにし、板形状の継手具５をサンドイッチパネル１の上下面に形成された表皮２の上面に接着層９ａを介在させて設置して加圧接着すれば良い。
【００２７】
これは、従来のコ字型状の継手具を接着材の塗布されたサンドイッチパネル１に差し込んで接着する必要がなくなり接着剤をかき取らないで製造が可能になるということである。
【００２８】
この実施の形態による製造方法は、ねじ穴６を有するコ字形状の継手具を、サンドイッチパネル１の端部に接着剤により接着する接合方法において、コ字形状の継手具を、ねじ穴６を有するＬ字形状の継手具４と板形状の継手具５に分割して製造する。
【００２９】
次に、Ｌ字形状の継手具４と板形状の継手具５は、Ｌ字形状の継手具４の凸部嵌合部７と板形状の継手具５の凹部嵌合部８により結合され、板形状の継手具５はサンドイッチパネル１の厚さ方向にＬ字形状の継手具４との間隔を自由に可変できる構造であり、サンドイッチパネル１の厚さに対応した所定の厚さに設置して接着し、加圧して硬化させることによって製造するものである。
【００３０】
また、Ｌ字形状の継手具４の凸部嵌合部７と板形状の継手具５の凹部嵌合部８により結合された板形状の継手具５はサンドイッチパネル１の表面上で横方向への移動に対しては、Ｌ字形状の継手具４の凸部嵌合部７と板形状の継手具５の凹部嵌合部８を嵌合させた後は横方向へは移動することができなくなるように一体化して剛性力が生ずる結合構造であり、さらに、各々の間隙を接着し、加圧して硬化させることによって製造するものである。
【００３１】
この製造方法によって、サンドイッチパネル１、表皮２、Ｌ字形状の継手具４および板形状の継手具５の製造公差によらず、接着層９の厚さが安定し、従って、安定した接着強度を得られ、かつ、サンドイッチパネル１とＬ字形状の継手具４および板形状の継手具５を接着する際に、接着剤をかき取られないという効果のある接合方法が可能である。
【００３２】
Ｌ字形状の継手具４および板形状の継手具５をサンドイッチパネル１、表皮２に結合する方法として、接着剤の代わりに、ビス、ネジ等により、Ｌ字形状の継手具４および板形状の継手具５とサンドイッチパネル１に結合する場合も良い。
【００３３】
以上説明したように、この発明によれば、サンドイッチパネル１とＬ字形状の継手具４、サンドイッチパネル１と板形状の継手具５、および、Ｌ字形状の継手具４と板形状の継手具５とを接着し、接着剤を加圧して硬化させることができるので、サンドイッチパネル１、Ｌ字形状の継手具４、および、板形状の継手具５の製造公差によらず接着層９の厚さが安定する、従って、安定した接着強度が得られるという効果がある。
【００３４】
また、従来のように、継手がコ字形状の剛性体であるため、接着面に圧力をかけることができないので、強度安全余裕を大きく見積もるために、必要以上に大きな接着面積を確保する必要がなくなるので、従来よりも重量を低減できるという利点がある。
【００３５】
また、Ｌ字形状の継手具４と板形状の継手具５は、サンドイッチパネル１の上下に置くようにして加圧接着すればよいので、サンドイッチパネル１に予め塗布しておいた接着剤がかき取られることがなく、従って、接着部以外に接着剤が侵入することもない。
【００３６】
【発明の効果】
この発明は、以上述べたように構成されているので、パネルおよび継手具の製造公差によらず、接着層の厚さが安定し、従って、安定した接着強度が得られ、かつ、パネルと継手具を接着する際に接着剤をかき取らない接合方法を提供できる。

A plate having an in-adhesion bonded portion formed separately from the L-shaped joint tool, which is disposed facing the upper surface of the sandwich panel 1 and the L-shaped joint tool 4 installed facing the end and the lower surface. The L-shaped coupling tool 4 and the plate-shaped coupling tool 5 are used by joining the sandwich panel 1 with an adhesive.
[0012]
FIG. 2 shows a perspective view of the coupling tool of the present invention, wherein 6 is a screw hole, 7 is a convex fitting portion installed in the L-shaped coupling tool 4, and 8 is installed in the plate-shaped coupling tool 5. 4 and 5 are the same as those in FIG.
[0013]
As shown in FIG. 2, a portion corresponding to a conventional U-shaped joint is divided into an L-shaped joint 4 having a screw hole 6 and a plate-shaped joint 5 having a fitting portion fitted therein. Manufactured.
[0014]
The L-shaped joint tool 4 and the plate-shaped joint tool 5 are arranged so as to form a U-shape, and the L-shaped joint tool 4 and the plate-shaped joint tool 5 are fitted and used together. To do.
[0015]
The L-shaped joint tool 4 and the plate-shaped joint tool 5 are coupled by the convex fitting part 7 of the L-shaped joint tool 4 and the concave fitting part 8 of the plate-shaped joint tool 5, and are plate-shaped. The joint tool 5 has a structure in which the distance from the L-shaped joint tool 4 can be freely changed in the thickness direction of the sandwich panel 1, and is used by being installed at a predetermined thickness corresponding to the thickness of the sandwich panel 1. The
[0016]
Further, the plate-shaped joint tool 5 coupled by the convex fitting part 7 of the L-shaped joint tool 4 and the concave part fitting part 8 of the plate-shaped joint tool 5 is laterally moved on the surface of the sandwich panel 1. Can move in the lateral direction after fitting the convex fitting part 7 of the L-shaped fitting 4 and the concave fitting part 8 of the plate-shaped fitting 5. It is a coupling structure that is integrated so as to be eliminated and a rigid force is generated.
[0017]
Depending on the application, it is also possible to use a plate-shaped joint tool 5 having an inset adhesive portion in the L-shaped joint tool 4 without the screw hole 6.
[0018]
3 shows a BB cross section of FIG. 1, wherein 9a is a thickness direction adhesive layer, 9b is a vertical adhesive layer, 10 is a spacer, 11 is a thickness dimension inside the fitting, and 12 is a sandwich panel thickness dimension. , 13 is the gap dimension between the sandwich panel and the fitting, 14 is the thickness dimension inside the L-shaped joint, 1 to 5 are the same as in FIG. 1, and 6 is the same as in FIG.
[0019]
In FIG. 3, an adhesive layer 9a is provided between the lower surface of the sandwich panel 1 having the skin 2 on the upper and lower surfaces and the L-shaped joint tool 4, and between the upper surface of the sandwich panel 1 and the plate-shaped joint tool 5. The spacer 10 is inserted in the thickness direction of the sandwich panel 1 and the adhesive filled in the gap between the end portion of the sandwich panel 1 and the L-shaped joint tool 4 from the three directions up and down is cured. Let
[0020]
The dimension of the sandwich panel 1 in the thickness direction is such that the L-shaped joint tool 4, the sandwich panel 1, and the plate-shaped joint tool 5 have a predetermined thickness in the thickness direction of the sandwich panel 1 on the respective adhesive layers 9a. In order to harden the adhesive filled in the adhesive layer 9a by pressing the spacer 10 processed with precision in the dimensions so as to be sandwiched, the dimension in the thickness direction of the sandwich panel 1 and the thickness of the adhesive layer 9a The balance between the dimensions and the thickness dimensions of the upper and lower surfaces of the adhesive layer 9a can be manufactured with high accuracy.
[0021]
Here, the spacer 10 is precisely processed with a predetermined thickness dimension corresponding to the thickness of the sandwich panel 1, and the width direction of the L-shaped joint tool 4 and the plate-shaped joint tool 5. A round bar or a square bar having a length corresponding to the length is used.
[0022]
Here, when a round bar is used, a product manufactured by accurately controlling the radial dimension is used. When a square bar is used, the height dimension corresponding to the thickness dimension of the sandwich panel 1 is used. Use the one manufactured with high precision.
[0023]
Further, as the spacer 10, a spherical one is used, and the spacer 10 is arranged so as to cover the entire bonding area of the L-shaped joint tool 4 and the plate-shaped joint tool 5 so as to cover the whole. It is also possible to do.
[0024]
The thickness dimension 14 inside the L-shaped joint tool 4 may be sufficiently larger than the sandwich panel thickness dimension 10.
[0025]
Thereby, the thickness of the adhesive layer 9a is the same as the thickness of the spacer 10 regardless of manufacturing tolerances of the sandwich panel 1, the L-shaped joint tool 4, and the plate-shaped joint tool 5.
[0026]
The L-shaped joint tool 4 is placed with the lower surface adhesive layer 9a of the skin 2 formed on the end of the sandwich panel 1 and the upper and lower surfaces of the sandwich panel 1 interposed therebetween, and the plate-shaped joint tool 5 is placed. What is necessary is just to press-bond and install it on the upper surface of the skin 2 formed on the upper and lower surfaces of the sandwich panel 1 with the adhesive layer 9a interposed.
[0027]
This means that it is not necessary to insert and bond a conventional U-shaped joint tool to the sandwich panel 1 to which an adhesive is applied, and manufacturing can be performed without scraping off the adhesive.
[0028]
The manufacturing method according to this embodiment is a joining method in which a U-shaped joint tool having a screw hole 6 is bonded to the end of the sandwich panel 1 with an adhesive. It is divided into an L-shaped joint tool 4 and a plate-shaped joint tool 5.
[0029]
Next, the L-shaped joint tool 4 and the plate-shaped joint tool 5 are coupled by the convex fitting part 7 of the L-shaped joint tool 4 and the concave fitting part 8 of the plate-shaped joint tool 5, The plate-shaped joint tool 5 has a structure in which the distance from the L-shaped joint tool 4 can be freely changed in the thickness direction of the sandwich panel 1, and is installed at a predetermined thickness corresponding to the thickness of the sandwich panel 1. It is manufactured by adhering and pressing to cure.
[0030]
Further, the plate-shaped joint tool 5 coupled by the convex fitting part 7 of the L-shaped joint tool 4 and the concave part fitting part 8 of the plate-shaped joint tool 5 is laterally moved on the surface of the sandwich panel 1. Can move in the lateral direction after fitting the convex fitting part 7 of the L-shaped fitting 4 and the concave fitting part 8 of the plate-shaped fitting 5. It is a joint structure that produces a rigid force by being integrated so as to disappear, and is manufactured by adhering each gap and curing it by applying pressure.
[0031]
By this manufacturing method, the thickness of the adhesive layer 9 is stabilized regardless of the manufacturing tolerances of the sandwich panel 1, the skin 2, the L-shaped joint tool 4 and the plate-shaped joint tool 5, so that a stable adhesive strength can be obtained. The obtained bonding method is effective in that the adhesive cannot be scraped off when the sandwich panel 1 is bonded to the L-shaped joint tool 4 and the plate-shaped joint tool 5.
[0032]
As a method of connecting the L-shaped joint tool 4 and the plate-shaped joint tool 5 to the sandwich panel 1 and the skin 2, the L-shaped joint tool 4 and the plate-shaped joint tool 4 are replaced by screws, screws or the like instead of the adhesive. It may be coupled to the joint tool 5 and the sandwich panel 1.
[0033]
As described above, according to the present invention, the sandwich panel 1 and the L-shaped joint tool 4, the sandwich panel 1 and the plate-shaped joint tool 5, and the L-shaped joint tool 4 and the plate-shaped joint tool. 5 and can be cured by pressurizing the adhesive, so that the thickness of the adhesive layer 9 does not depend on the manufacturing tolerances of the sandwich panel 1, the L-shaped joint tool 4, and the plate-shaped joint tool 5. Therefore, there is an effect that a stable adhesive strength can be obtained.
[0034]
In addition, since the joint is a U-shaped rigid body as in the past, pressure cannot be applied to the bonding surface, so it is necessary to secure an unnecessarily large bonding area in order to estimate the safety margin for strength. Therefore, the weight can be reduced more than before.
[0035]
Further, since the L-shaped joint tool 4 and the plate-shaped joint tool 5 may be pressure-bonded so as to be placed on the top and bottom of the sandwich panel 1, the adhesive previously applied to the sandwich panel 1 is scraped. Therefore, the adhesive does not enter other than the bonded portion.
[0036]
【The invention's effect】
Since the present invention is configured as described above, the thickness of the adhesive layer is stable regardless of the manufacturing tolerances of the panel and the joint, and thus stable adhesive strength can be obtained, and the panel and joint can be obtained. It is possible to provide a joining method that does not scrape off the adhesive when the tools are bonded.
