Description

本発明は、広域な壁面構造体、例えば、鉄道車両の各部構体をダブルスキン構造にて形成するのに好適な摩擦接合用の中空形材対に関するものである。   The present invention relates to a hollow shape material pair for friction joining suitable for forming a wide-area wall structure, for example, each structure of a railway vehicle with a double skin structure.

鉄道車両では、一層の高速化のための軽量化と、安全などに対応するための高剛性化とが要求され、併せ低コスト化も望まれている。これに応えるのに、表板と裏板との間が複数の連結板によって連結されたアルミニウム製の中空形材が採用され、これを摩擦接合によって接合し所定の広さの構体がダブルスキン構造にて形成されている（例えば、特許文献１〜４参照。）。摩擦接合は主としてＦｒｉｃｔｉｏｎ Ｓｔｉｒ Ｗｅｌｄｉｎｇと称されるもので、摩擦攪拌接合ないしは摩擦攪拌溶接と和訳されている。その具体的な方法は先端にプローブといわれる突起物のあるツールを回転させながら突き合わせた接合部に押し込み、摩擦熱によって軟化した材料を攪拌（塑性流動化）し接合する。つまり、溶解溶接でなく固相接合なので金属組織は強加工された微細化した組織となり機械的性質に優れている。例えば、材料を溶かさない低歪み接合ができ、作業環境も改善され、省エネが図れる。また、熟練が不要である。   Railway vehicles are required to be lighter for higher speed and to have higher rigidity to cope with safety, and cost reduction is also desired. In response to this, a hollow aluminum material is used in which the front and back plates are connected by a plurality of connecting plates, which are joined by friction bonding to form a structure with a predetermined width. (For example, refer to Patent Documents 1 to 4). Friction welding is mainly called Friction Stir Welding and is translated into friction stir welding or friction stir welding. The specific method is that a tool having a projection called a probe at the tip is rotated and pushed into the joined part, and the material softened by frictional heat is stirred (plastic fluidized) and joined. In other words, since it is not solid-state welding but solid phase bonding, the metal structure becomes a strongly processed and refined structure and is excellent in mechanical properties. For example, low strain bonding that does not melt the material can be achieved, the working environment can be improved, and energy can be saved. Moreover, skill is unnecessary.

しかし、このような接合方法を採用して中空形材の表板どうし、裏板どうしを突き合わせて摩擦接合するには、表板どうし、裏板どうしを突き合わせて、その突き合わせ部に外面側からプローブを持ったツールを回転させて押し付けながら、突き合わせ部に沿って互いを相対移動させることになるが、表板どうし、裏板どうしの突き合わせ部に逃げがあると十分な摩擦効果、攪拌効果が得られない。そこで、特許文献１〜４はいずれも、中空形材の表板どうし、裏板どうしを突き合わせて摩擦接合するのに、それら突き合わせ部を中空形材の表板および裏板間を連結する連結板の突っ張り、つまり座屈強度によって支えるようにした摩擦接合用の中空形材を提供している。
特許第３２２８４６８号公報 特許第３２２８４６７号公報 特許第３２８２７２５号公報 特許第３４５９１９７号公報 However, in order to frictionally weld the front and back plates of hollow shapes by using such a joining method, the front and back plates are butted against each other, and the probe is connected to the butted portion from the outer surface side. While rotating and pressing a tool with a lip, the tool moves relative to each other along the abutting part.However, if there is clearance between the abutting parts of the front and back plates, sufficient friction and stirring effects can be obtained. I can't. Therefore, in all of Patent Documents 1 to 4, in order to frictionally join the hollow shape front plates and the back plates to each other, the connecting plate is used to connect the butted portions between the front and back plates of the hollow shape material. We provide a hollow material for friction bonding that is supported by the tension, that is, buckling strength.
Japanese Patent No. 3228468 Japanese Patent No. 3228467 Japanese Patent No. 3282725 Japanese Patent No. 3459197

しかし、上記いずれの先行技術も、摩擦接合負荷を連結板の突っ張り作用によって受け止め、突き合わせた一対の中空形材どうしが摩擦接合負荷の方向に逃げ合うのを防止することはできても、摩擦接合初期においては回転しているツールの押し付けは突き合わせている一対の中空形材どうしをしばしば押し離すように働くことには効果がなく、摩擦接合する一対の中空形材の突き合わせ状態に狂いやずれが生じやすい。   However, in any of the above prior arts, the friction welding load can be received by the tensioning action of the connecting plate, and the pair of hollow shaped members can be prevented from escaping in the direction of the friction welding load. In the initial stage, the pressing of the rotating tool is not effective in often pushing the pair of hollow shapes to push apart, and the butt state of the pair of hollow shapes to be frictionally joined is not correct. Prone to occur.

このため、従来、摩擦接合し合う一対の形材を突き合わせ状態にクランプしておいたり、突き合わせ部の複数箇所を前もって溶接するなどし仮止めしたりすることを余儀なくされ、付帯設備や付帯作業に経費が嵩んでいる。   For this reason, conventionally, it has been necessary to clamp a pair of profiles that are friction-bonded in a butted state, or to temporarily fix a plurality of locations of the butted portion in advance, for example, for ancillary equipment or incidental work. Expenses are increasing.

また、これらに代えて一対の中空形材どうしに突き合わせ状態を保つ嵌め合わせ部を押出し成形時に設けるようにしてもよいが、長手方向での嵌め合いであると長尺な中空形材をその長さ分動かさないと嵌め合わせができず実用的ではない。そこで、簡単な仮止め構造の実現が望まれるが、表板どうしの突き合わせ部、裏板どうしの突き合わせ部において前記間擦接合負荷を支持する構造と強度が必要なことから、そのような技術はまだ提供されていない。   Instead of these, a fitting portion that keeps the butted state between the pair of hollow shapes may be provided at the time of extrusion molding, but if the fitting is in the longitudinal direction, a long hollow shape is long. If it does not move a little, it can not be fitted and is not practical. Therefore, it is desired to realize a simple temporary fixing structure, but such a technique is necessary because the structure and strength that support the interstitial joint load are required at the abutting portion between the front plates and the abutting portion between the back plates. Not yet provided.

本発明の目的は、このような現状に鑑み、一対の中空形材の突き合わせと同時に簡単に仮止めして、しかも、表板どうしおよび裏板どうしの各突き合わせ部での摩擦接合負荷を従分に受け止め、首尾よく容易かつ安価に摩擦接合することができる摩擦接合用の中空形材対を提供することにある。   In view of such a current situation, the object of the present invention is to simply temporarily fix a pair of hollow shapes at the same time as the butting of the pair of hollow shapes, and to appropriately determine the friction welding load at each butting portion between the front and back plates. It is an object of the present invention to provide a pair of hollow members for friction joining that can be easily and inexpensively and smoothly joined.

上記のような課題を達成するために、本発明の摩擦接合用の中空形材対は、表裏の板間が複数の連結板によって連結されて中空とされた中空形材を一対組合せ備え、それらの表裏の板どうしを互いに突き合わせて面直角方向からの回転子の押し当てにより摩擦接合される接合端部を有し、これら接合端部に、前記表板どうしの突き合わせ部と、裏板どうしの突き合わせ部とで、それらの少なくとも表板どうしの一方と裏板どうしの一方とに連結板から延びた自由端片を有して突き合わさり、互いが突き合わせ方向に弾性嵌合して反突き合わせ方向に引っ掛かり合い一対の中空形材を突き合わせ状態に仮止めする仮止め嵌合部と、表板どうしの突き合わせ部と裏板どうしの突き合わせ部との間での突っ張り、にて、前記各自由端片の自由を阻害しないように位置して対応する表板どうしまたはおよび裏板どうしの突き合わせ部に働く摩擦接合負荷を受け止める突っ張り部と、を設けたことを１つの特徴としている。 In order to achieve the above-described problems, the pair of hollow members for friction bonding according to the present invention includes a pair of hollow members in which the front and back plates are connected to each other by a plurality of connecting plates and are hollow. The front and back plates of each other are joined to each other and frictionally joined by pressing the rotor from the direction perpendicular to the surface, and the joined end portions of the front plate and the back plates are joined together. At the abutting portion, at least one of the front plates and one of the back plates have a free end piece extending from the connecting plate and abut each other. a temporary fixing fitting portion is temporarily fixed in a state abutting a pair of hollow profile mutual caught, bracing between the abutting portions of the front plate to each other and back plate each other in the butted portions, boiled, of the respective free end pieces Hinder freedom Position to have a bracing portion receive the friction bonding load acting on the butt of each other corresponding table plate each other or and back plate, one of the features in that a so no.

このような構成では、一対の中空形材の接合端部を、それらの少なくとも表板どうしの一方と裏板どうしの一方とに連結板から延びた自由端片を有して、突き合わせるのと同時に、表板どうしの突き合わせ部と裏板どうしの突き合わせ部との仮止め嵌合部が、それらの自由端片の突っ張り部による邪魔のない表裏でバランスのとれた弾性変形を伴い突き合わせ方向に表裏で偏りなく嵌まり合って反突き合わせ方向に引っ掛かり合うことで、一対の中空形材を突き合わせ状態に簡単に仮止めし、摩擦接合時に一対の中空形材どうしの突き合わせ状態に狂いやずれが生じるのを防止することができる。また、一対の中空形材の接合端部における表板どうしの突き合わせ部および裏板どうしの突き合わせ部間、または、表板どうしの突き合わせ部と裏板間および裏板どうしの突き合わせ部と表板間での突っ張り部の突っ張りによって、それら突き合わせ部に働く摩擦接合負荷を受け止め、どの突き合わせ部においても逃げのない適正な摩擦接合が行われるようにする。   In such a configuration, the joining end portions of the pair of hollow profiles have a free end piece extending from the connecting plate on at least one of the front plates and one of the back plates, and abut each other. At the same time, the temporarily fixed fitting part between the abutting part of the front and back plates and the abutting part of the back plates is front and back in the abutting direction with elastic deformation balanced between the front and back by the stretched part of the free end pieces. By fitting together and catching in the anti-butting direction, the pair of hollow shapes can be easily temporarily fixed to the butted state, and the abutting state of the pair of hollow shapes will be distorted or displaced during friction welding. Can be prevented. In addition, between the butted parts of the front plates at the joining end of the pair of hollow profiles and the butted parts of the back plates, or between the butted parts of the front plates and the back plate, and between the butted parts of the back plates and the front plate The frictional load acting on the abutting parts is received by the tensioning of the abutting parts, and proper frictional joining without any escape is performed in any of the abutting parts.

本発明の摩擦接合用の中空形材対は、また、表裏の板間が複数の連結板によって連結されて中空とされた中空形材を一対組合せ備え、それらの表裏の板どうしを互いに突き合わせて面直角方向からの回転子の押し当てにより摩擦接合される接合端部を有し、これら接合端部における表板どうしの突合せ部と、裏板どうしの突合せ部とに、一対の中空形材の一方における表板および裏板の連結板から延びる自由端片と、他方における表板および裏板の連結板が突っ張り部として位置する端部との間で、前記自由端片の弾性変形を利用して突き合わせ方向に嵌まり合い反突き合わせ方向に引っ掛かり合って、一対の中空形材を突き合わせ状態に仮止めする仮止め嵌合部を設け、表板どうしの突き合わせ部と裏板どうしの突き合わせ部とに働く摩擦接合負荷をそれら突き合わせ部間の連結板が突っ張り部となって受け止めるようにしたことを別の特徴としている。   The pair of hollow members for friction welding according to the present invention also includes a pair of hollow members in which the front and back plates are connected to each other by a plurality of connecting plates so as to be hollow, and the front and back plates are brought into contact with each other. It has joint end parts that are friction-bonded by pressing the rotor from a direction perpendicular to the plane, and a pair of hollow profile members are connected to the butted parts of the front plates at the joined end parts and the butted parts of the back plates. Utilizing elastic deformation of the free end piece between the free end piece extending from the connecting plate of the front plate and the back plate on one side and the end portion where the connecting plate of the front plate and the back plate on the other side is positioned as a tension portion. Are fitted in the butting direction and hooked in the anti-butting direction to provide a temporary fitting part that temporarily holds the pair of hollow profiles in the butted state, with the abutting part between the front plates and the abutting part between the back plates Working friction Is another characterized in that the engagement load connecting plate between them butted portion was set to receive in a strut section.

このような構成では、１つの特徴における、表板どうしの突き合わせ部と裏板どうしの突き合わせ部との仮止め嵌合部で、突き合わせ方向に嵌まり合って反突き合わせ方向に引っ掛かり合うことが、これら接合端部における表板どうしの突合せ部と、裏板どうしの突合せ部とで、一対の中空形材の一方における表板および裏板の連結板から延びる自由端片の表裏でバランスのとれた弾性変形にて偏りなくなされ、一対の中空形材を突き合わせ状態に簡単に仮止めし、摩擦接合時に一対の中空形材どうしの突き合わせ状態に狂いやずれが生じるのを防止することができる。また、前記連結板が、表板どうしの突き合わせ部と裏板どうしの突き合わせ部との間に位置して、これら突き合わせ部に働く摩擦接合負荷を突っ張り部となって受け止め、どの突き合わせ部においても逃げのない適正な摩擦接合が行われるようにする。   In such a configuration, in one feature, in the temporarily fixed fitting portion of the butted portion of the front plates and the butted portion of the back plates, it can be fitted in the butting direction and hooked in the anti-butting direction. Elasticity balanced at the front and back of the free end piece that extends from the front plate and the back plate connecting plate in one of the pair of hollow shape members, with the butted portion between the front plates at the joining end and the butted portion between the back plates It is made uniform by deformation, and the pair of hollow profiles can be simply temporarily fixed to the butted state, and it is possible to prevent deviation and deviation from occurring in the butted state of the pair of hollow profiles at the time of friction welding. In addition, the connecting plate is located between the abutting portions of the front plates and the abutting portions of the back plates, receives the frictional joint load acting on these abutting portions as a strut portion, and escapes at any abutting portion. Make sure that proper friction welding is performed.

突っ張り部が、中空である、さらなる構成では、
突っ張り部が中空であると、摩擦接合熱を奪う蓄熱容量を大きくしたり、あまり重量化しないで摩擦接合負荷に対する支持強度を高められる。 In a further configuration, where the struts are hollow,
If the strut is hollow, the heat storage capacity for depriving the frictional joint heat can be increased, and the supporting strength against the frictional joint load can be increased without increasing the weight.

突っ張り部が、一対の中空形材の接合端部における表板どうし、裏板どうしの仮止め嵌合を伴なう突き合わせに際して、突っ張り位置に組合わさるよう一方の中空形材に設けられた一方側突っ張り部と、他方の中空形材に設けられた他方側突っ張り部とがなす、さらなる構成では、
突っ張り部は、表板どうしの仮止め嵌合部を持った突き合わせ部と裏板どうしの仮止め嵌合部を持った突合せ部との間に位置するが、それらの一方側に設けられた一方側突っ張り部と他方側に設けられた他方側突っ張り部とに互いに分かれた非連結部として、それらを接合端部に持つ表板および裏板の自由を拘束せずに自由端片であることを可能にして、自由端片を表裏バランスよく増設できるようにしながら、互いの突っ張り位置への組み合わせにて、各突き合わせ部に働く摩擦接合負荷を受け止めることができる。また、表板どうしの突き合わせ部および裏板どうしの突き合わせ部とが摩擦接合負荷が働く方向に対向し合う構成と、側方へずれ合う構成とが採用でき、側方へずれ合う構成では一方側突っ張り部と他方側突っ張り部との突っ張り位置が斜め配置となるのを利用して、一方側突っ張り部を有する一方の中空形材における表板の突き合わせ部と裏板の途中部とを連結した斜め配置の連結板と、他方側突っ張り部を有する他方の中空形材における裏板の端部と表板の途中とを連結した斜め配置の連結板とが、組み合わせ構造の突っ張り部と分担し合って摩擦接合負荷を受け止める支持構造、および正立三角形部と倒立三角形部とが交互に並ぶトラス構造が実現する。 One side provided on one hollow profile so that the stretched portion is combined with the stretched position at the time of abutment involving temporary fixing fitting between the front and back plates at the joint end of the pair of hollow profiles In a further configuration formed by the tension part and the other side tension part provided in the other hollow shape member,
The struts are located between the abutting part with the temporary fixing fitting part between the front plates and the abutting part with the temporary fixing fitting part between the back plates, but one provided on one side of them It is a free end piece without constraining the freedom of the front plate and the back plate having the joint end portion as a non-connecting portion separated from each other in the side stretch portion and the other side stretch portion provided on the other side. In this manner, the free end pieces can be added with a good balance between the front and back sides, and the friction joining load acting on each abutting portion can be received in combination with the tensioned positions. In addition, a configuration in which the butted portion of the front plates and the butted portion of the back plates face each other in the direction in which the friction welding load works and a configuration in which the side plates are displaced in the lateral direction can be adopted. Using the fact that the stretched position of the stretched portion and the stretched portion on the other side is obliquely arranged, the diagonally connecting the butted portion of the front plate and the middle portion of the back plate in one hollow profile having the one-side stretched portion The connecting plate of the arrangement and the connecting plate of the diagonal arrangement in which the end portion of the back plate and the middle of the front plate in the other hollow shape member having the other side tension part are shared with the tension part of the combination structure.

The hollow shape members 11 and 12 can be simply temporarily fixed to the abutting state shown in the figure, and it is possible to prevent the butt state between the pair of hollow shape members 11 and 12 from being distorted or displaced during friction welding. At the same time, such as the example shown in FIG. 1, the example shown in FIG. 2, the example shown in FIG. 4, the example shown in FIG. 5, and the example shown in FIG. Between the front plate 1, the butted portion 13 and the back plate 2, between the butted portions 14, or between the front plate 1, the butted portion 13 and the back plate 2 as in the example shown in FIG. By receiving the striking portion 16 and the back plate 2, between the butting portion 14 between the two back plates 2, 2 and the striking portion 17 between the middle portions 14b of the front plate 1, the friction joining load acting on these butting portions 13, 14 is received. Appropriate friction welding is performed so that there is no escape at any butt.

これらの結果、一対の中空形材１１、１２の接合端部１１ａ、１２ａ間の表板１、１どうしの突き合わせ部１３と裏板２、２どうしの突き合わせ部１４とを摩擦接合するのに、各突き合わせ部１３、１４の仮止め嵌合部１８、１９が表裏板１、２の自由端片２１による表裏でのバランスのとれた弾性変形を伴い嵌合し合って突き合わせ状態に簡単に仮止めして互いの位置に狂いやずれが生じるのを防止するのに併せ、各突き合わせ部１３、１４ではそこに働く摩擦接合負荷を突っ張り部１５、１６、１７の突っ張りによって受け止めて、逃げのない適正な摩擦接合が行える。なお、自由端片２１の連結板３からの延び長さは、前記仮止め嵌合部１８、１９の嵌合が無理無く行えて、しかも、不用意には嵌合が外れない程度の弾性変形が得られる範囲が好適であり、例えば、表裏板１、２の厚みの５倍程度以上が１つの目安になるが、これに限られることはない。   As a result, in order to frictionally join the front plate 1 between the joining end portions 11a and 12a of the pair of hollow shape members 11 and 12, the butted portion 13 between the back plate 2 and the butted portion 14 between the two, The temporarily fixed fitting portions 18 and 19 of the respective butted portions 13 and 14 are fitted together with balanced elastic deformation on the front and back sides by the free end pieces 21 of the front and back plates 1 and 2 and are simply temporarily fixed to the butted state. In addition, in order to prevent deviations and deviations from occurring in each other's position, the abutting portions 13 and 14 receive the frictional joint load acting on the abutting portions by the thrusting of the thrusting portions 15, 16 and 17, and do not escape Frictional welding can be performed. The extension length of the free end piece 21 from the connecting plate 3 is such that the temporary fixing fitting portions 18 and 19 can be easily fitted, and the elastic deformation is such that the fitting cannot be removed carelessly. Is suitable. For example, about 5 times or more the thickness of the front and back plates 1 and 2 is one guideline, but is not limited thereto.

図１に示す例、図２に示す例では、特に、中空形材１１、１２の接合端部１１ａ、１２ａにおける表板１、１どうしの突合せ部１３と、裏板２、２どうしの突合せ部１４とに、一方の中空形材１２における表板１および裏板１の連結板３から延びる自由端片２１、２１と、他方の中空形材１１における表板１および裏板２の連結板３が突っ張り部１５として位置する端部との間で、表裏の自由端片２１、２１の弾性変形を利用して突き合わせ方向に嵌まり合い反突き合わせ方向に引っ掛かり合って、一対の中空形材１１、１２を突き合わせ状態に仮止めする仮止め嵌合部１８、１９を有したものとし、表板１、１どうしの突き合わせ部１３と裏板２、２どうしの突き合わせ部１４とに働く摩擦接合負荷をそれら突き合わせ部１３、１４間の連結板３が突っ張り部１５となって受け止めるようにしている。   In the example shown in FIG. 1 and the example shown in FIG. 2, in particular, the front plate 1, the butting portion 13 between the front plates 1 and 12, and the butting portion between the back plates 2 and 2, at the joint ends 11 a and 12 a of the hollow shape members 11 and 12. 14, free end pieces 21, 21 extending from the connection plate 3 of the front plate 1 and the back plate 1 in one hollow shape member 12, and the connection plate 3 of the front plate 1 and the back plate 2 in the other hollow shape member 11. Are fitted in the abutting direction and hooked in the opposite abutting direction using elastic deformation of the free end pieces 21 and 21 on the front and back sides, and a pair of hollow profiles 11, It is assumed that there are provisional fitting portions 18 and 19 for temporarily fastening 12 to the butted state, and the friction bonding load acting on the front plate 1, the butted portion 13 between the front plate 1 and the back plate 2, and the butted portion 14 between the two is applied. The connection between these butting parts 13 and 14 Plate 3 is as receive become Brace portion 15.

これにより、表板１、１どうしの突き合わせ部１３と裏板２、２どうしの突き合わせ部１４での仮止め嵌合部１８、１９が、突き合わせ方向に嵌まり合って反突き合わせ方向に引っ掛かり合うことが、一方の中空形材１２における表板１および裏板２の連結板３から延びる自由端片２１、２１の表裏でバランスのとれた弾性変形にて偏りなくなされる。併せ、他方の中空形材１１の連結板３が突っ張り部１５をなして、表板１、１どうしの突き合わせ部１３と裏板２、２どうしの突き合わせ部１４との間に同心関係で位置して、これら突き合わせ部１３、１４に働く摩擦接合負荷に対して偏りなく突っ張って十分に受け止め、どの突き合わせ部１３、１４においても表裏同じ位置にて逃げのない適正な摩擦接合が行われるようになる。   Thereby, the temporarily fixed fitting parts 18 and 19 in the abutting part 13 and the back plate 2 and the abutting part 14 between the front plates 1 and 1 are fitted in the abutting direction and hooked in the anti-abutting direction. However, there is no bias due to balanced elastic deformation on the front and back of the free end pieces 21, 21 extending from the front plate 1 and the connecting plate 3 of the back plate 2 in one hollow shape member 12. In addition, the connecting plate 3 of the other hollow shape member 11 forms a stretched portion 15, and is positioned concentrically between the front plate 1, the butted portion 13 between the back plate 2 and the butted portion 14 between the back plate 2 and 2. Thus, the friction welding load acting on the abutting portions 13 and 14 is stretched without any bias and is sufficiently received, and any of the abutting portions 13 and 14 can perform appropriate friction joining without any escape at the same front and back positions. .

この結果、各突き合わせ部１３、１４間の連結板３は、突っ張り部１５として働くものの、他の連結板３との配置や補強のバランスが採れやすく、構造が簡単で安価に実現する。また、突っ張り部１５としての連結板３は場合により、図１に示す例のように他の位置の連結板３よりも厚くして支持強度を高められるし、図２に示す例のように中空の突っ張り部１５とすると、摩擦接合熱を奪う蓄熱容量を大きくしたり、あまり重量化しないで摩擦接合負荷に対する支持強度を高められる。   As a result, although the connecting plate 3 between the butted portions 13 and 14 functions as the stretched portion 15, it is easy to balance the arrangement and reinforcement with the other connecting plates 3, and the structure is simple and inexpensive. In some cases, the connecting plate 3 as the stretched portion 15 can be made thicker than the connecting plate 3 at other positions as in the example shown in FIG. 1 to increase the support strength, and it can be hollow as in the example shown in FIG. If the tension portion 15 is used, it is possible to increase the heat storage capacity for depriving the frictional joint heat and to increase the support strength against the frictional joint load without increasing the weight.

図３に示す例、図６に示す例では、特に、一対の中空形材１１、１２の接合端部１１ａ、１２ａにおける表板１、１どうしの突き合せ部１３と、裏板２、２どうしの突き合せ部１４とに、一方の中空形材１２の表板１の連結板３から延びる自由端片２１と他方の中空形材１１における裏板２の連結板３が突っ張り部１５をなして位置する端部との間、および他方の中空形材１１における裏板２の連結板３から延びる自由端片２１と一方の中空形材１２における表板１の連結板３が突っ張り部１５をなして位置する端部との間に、仮止め嵌合部１８、１９を有して、自由端片２１、２１の弾性変形を利用して突き合わせ方向に嵌まり合い反突き合わせ方向に引っ掛かり合って一対の中空形材１１、１２を突き合わせ状態に仮止めすることができ、併せ、表板１、１どうしの突き合わせ部１３に働く摩擦接合負荷は、一方の中空形材１１における表板１の突き合わせ部１３と裏板２の途中部１３ｂとの間に位置する連結板３がなす突っ張り部１６の突っ張りによって、裏板２、２どうしの突き合わせ部１４とに働く摩擦接合負荷は、他方の中空形材１２の裏板２の突き合わせ部１４と表板１の途中部１４ｂとの間に位置する連結板３がなす突っ張り部１７の突っ張りによって、それぞれ個々に受け止めることができる。   In the example shown in FIG. 3 and the example shown in FIG. 6, in particular, the front plate 1, the butted portion 13 of the pair of hollow shape members 11, 12 at the joining end portions 11 a, 12 a, and the back plates 2, 2 are mutually connected. The free end piece 21 extending from the connecting plate 3 of the front plate 1 of one hollow shape member 12 and the connecting plate 3 of the back plate 2 of the other hollow shape member 11 form a butt portion 15. The free end piece 21 extending from the connecting plate 3 of the back plate 2 in the other hollow shape member 11 and the connecting plate 3 of the front plate 1 in the one hollow shape member 12 form the tension portion 15. A pair of temporary fastening fittings 18 and 19 that are fitted in the butting direction and hooked in the counter-butting direction using the elastic deformation of the free end pieces 21 and 21. The hollow shape members 11 and 12 can be temporarily fixed to the butted state. In addition, the friction bonding load acting on the abutting portion 13 between the front plates 1 and 1 is a connecting plate 3 located between the abutting portion 13 of the front plate 1 and the middle portion 13b of the back plate 2 in one hollow shape member 11. The friction bonding load acting on the back plate 2 and the butting portion 14 between the back plate 2 and the butting portion 14 between the back plate 2 and the two butting portions 16 is formed between the butting portion 14 of the back plate 2 of the other hollow profile 12 and the middle portion 14b of the front plate 1. The connecting plate 3 positioned between the two can be individually received by the protrusions 17 formed by the connecting plate 3.

この結果、表板１、１どうしの突き合わせ部１３と裏板２、２どうしの突き合わせ部１４とを、図示するように摩擦接合負荷が働く方向に対して自由端片２１を設けた長さに対応して左右に位置ずれした構成として、各突き合わせ部１３、１４での摩擦接合負荷を支持する突っ張り部１５の配置が突き合わせ部１３、１４の位置ずれによって分散し、他の連結板３との配列バランスが取りやすいものとなる。   As a result, the front plate 1 and the butted portion 13 between the back plate 2 and the butted portion 14 between the back plate 2 and the two butted portions 14 have a length in which the free end piece 21 is provided in the direction in which the frictional bonding load acts as shown in the figure. Correspondingly, the arrangement of the struts 15 that support the friction welding load at each of the abutting portions 13 and 14 is dispersed due to the misalignment of the abutting portions 13 and 14 as a configuration shifted to the left and right. Arrangement balance is easy to take.

図４に示す例、図５に示す例、図６に示す例では、さらに、突っ張り部１５が、一対の中空形材１１、１２の接合端部１１ａ、１２ａにおける表板１、１どうし、裏板２、２どうしの仮止め嵌合部１８、１９での嵌合を伴なう突き合わせに際して、突っ張り位置に組合わさるよう一方の中空形材１１に設けられた一方側突っ張り部１５ａと、他方の中空形材１２に設けられた他方側突っ張り部１５ｂとがなしている。これにより、突っ張り部１５は、表板１、１どうしの仮止め嵌合部１８を持った突き合わせ部１３と裏板２、２どうしの仮止め嵌合部１９を持った突合せ部１４との間に位置するが、それらの一方側に設けられた一方側突っ張り部１５ａと他方側に設けられた他方側突っ張り部１５ｂとに互いに分かれた非連結支持板３ａとして機能し、それらを接合端部１１ａ、１２ａに持つ表板１および裏板２の自由を拘束せずに自由端片２１であることを可能にして、図４に示す例、図５に示す例のように自由端片２１を表裏バランスよく増設、具体的には倍加できるようにしながら、互いの突っ張り位置への組み合わせにて、各突き合わせ部１３、１４に働く摩擦接合負荷を受け止めることができる。   In the example shown in FIG. 4, the example shown in FIG. 5, and the example shown in FIG. 6, the struts 15 further include the front plates 1, 1, and the back of the joint ends 11 a, 12 a of the pair of hollow shapes 11, 12. When the plates 2 and 2 are mated together with the temporarily fixed fitting portions 18 and 19, the one-side stretched portion 15a provided in one hollow shape member 11 is combined with the stretched position, and the other The other side protruding portion 15b provided in the hollow shape member 12 is formed. Thus, the strut 15 is between the abutting portion 13 having the front plate 1 and the temporary fixing fitting portion 18 between the front plate 1 and the abutting portion 14 having the temporary fixing fitting portion 19 between the back plate 2 and two. However, it functions as an unconnected support plate 3a that is divided into a one-side protruding portion 15a provided on one side thereof and an other-side protruding portion 15b provided on the other side, and these are connected to the joining end portion 11a. , 12a can be the free end piece 21 without restricting the freedom of the front plate 1 and the back plate 2, and the free end piece 21 is turned upside down as in the example shown in FIG. 4 and the example shown in FIG. While being able to add in a balanced manner, specifically, to double, it is possible to receive the frictional joint load acting on each of the abutting portions 13 and 14 by a combination to the tension position.

また、表板１、１どうしの突き合わせ部１３および裏板２、２どうしの突き合わせ部１４とが、図４に示す例、図５に示す例のように摩擦接合負荷が働く方向に対向し合う構成と、図６に示す例の側方へずれ合う構成とが採用でき、図６に示す例の側方へずれ合う構成では一方側突っ張り部１５ａと他方側突っ張り部１５ｂとの突っ張り位置が斜め配置となるのを利用して、一方側突っ張り部１５ａを有する一方の中空形材１１における表板１の突き合わせ部１３と裏板２の途中部１３ｂとを連結した斜め配置の連結板３と、他方側突っ張り部１５ｂを有する他方の中空形材１２における裏板２の突き合わせ部１４と表板１の途中部１４ｂとを連結した斜め配置の連結板３とが、組み合わせ構造の突っ張り部１５と分担し合って摩擦接合負荷を受け止める支持構造が実現するし、図７に示すような正立三角形部と倒立三角形部とが交互に並ぶトラス構造が実現する。   Moreover, the butting part 13 of the front plate 1 and 1 and the butting part 14 of the back plate 2 and 2 face each other in the direction in which the friction welding load acts as in the example shown in FIG. 4 and the example shown in FIG. The configuration and the configuration in which the example shown in FIG. 6 is shifted to the side can be adopted. In the configuration in which the configuration is shifted to the side in the example shown in FIG. 6, the extension position between the one-side extension unit 15a and the other-side extension unit 15b is oblique. Utilizing the arrangement, the connecting plate 3 in an oblique arrangement in which the butting portion 13 of the front plate 1 and the middle portion 13b of the back plate 2 in the one hollow shape member 11 having the one side protruding portion 15a are connected, In the other hollow shape member 12 having the other side protruding portion 15b, the diagonally arranged connecting plate 3 connecting the butted portion 14 of the back plate 2 and the middle portion 14b of the front plate 1 is shared with the protruding portion 15 of the combined structure. Friction welding load It support structure to receive is realized, an erecting triangular section as shown in FIG. 7 and the inverted triangular section truss structure is realized alternating.

このような組み合わせ突っ張り部１５によっては、また、この嵌め合いでの一方側突っ張り部１５ａおよび他方側突っ張り部１５ｂが突っ張り合う位置に進入する際に組み合わせ突っ張り部１５に表板１および裏板２間の拡張作用を得て前記仮止め嵌合部１８、１９の嵌め合わせでの隙間をなくして摩擦接合時の逃げになるのを回避し摩擦接合が首尾よく達成されるようにすることができる。このような拡張をもたらしやすくするために図４に示す例、図５に示す例、図６に示す例では一方側突っ張り部１５ａと他方側突っ張り部１５ｂとの突っ張り合い位置への進入境界部に、表板１および裏板２の面に平行な進入方向に対して傾斜した傾斜部１５ｃを設けて、突っ張り合う位置への進入にさいして楔作用を営み組み合わせ突っ張り部１５を拡張させるようにしている。また、この楔作用は一方側突っ張り部１５ａおよび他方側突っ張り部１５ｂの突っ張り合い位置への進入初期の引っ掛かりや干渉無しに容易に突っ張り合い位置に進入できるようにして、しかも、その後の一層の進入によって前記組み合わせ突っ張り部１５の拡張を生んで仮止め嵌合部１８、１９の隙間をなくす圧入状態が得られるようにする。特に、図６に示す例では、一方側突っ張り部１５ａおよび他方側突っ張り部１５ｂは突っ張り位置への進入し合って後、突っ張り位置ではその進入方向に対して斜めの方向に突っ張り合う関係から、鉤型の突っ張り端部１５ｄ、１５ｅを設けて、突っ張り合い位置から外れるのを防止している。   Depending on the combination struts 15, when the one side struts 15 a and the other side struts 15 b in this fitting enter the position where the struts are struggling, the combination struts 15 may be placed between the front plate 1 and the back plate 2. Thus, it is possible to eliminate the gap in the fitting of the temporary fixing fitting portions 18 and 19 to avoid the escape at the time of friction welding, and to achieve the friction welding successfully. In order to facilitate such expansion, in the example shown in FIG. 4, the example shown in FIG. 5, and the example shown in FIG. 6, at the entry boundary to the striking position between the one-side strut 15 a and the other-side strut 15 b In addition, an inclined portion 15c that is inclined with respect to the approach direction parallel to the surfaces of the front plate 1 and the back plate 2 is provided so that the combined thrust portion 15 is expanded by performing a wedge action when entering the striking position. Yes. Further, this wedge action allows the one side strut 15a and the other side strut 15b to enter the striking position easily without any initial catch or interference with the striking position of the other side striking section 15b. As a result, the combination struts 15 are expanded so that a press-fitted state in which the clearance between the temporarily fixed fitting portions 18 and 19 is eliminated can be obtained. In particular, in the example shown in FIG. 6, the one-side stretched portion 15 a and the other-side stretched portion 15 b enter the stretched position, and then in the stretched position, they are stretched in an oblique direction with respect to the entry direction. Protruding end portions 15d and 15e of the mold are provided to prevent the mold from being removed from the striking position.

一方、図５に示す例での、他方の中空形材１２に設けた他方側突っ張り部１５ｂは、表板１、裏板２の一方、具体例では表板１の裏面から断面鉤型に突出した部分として形成することで、他方の中空形材１２の接合端部１２ａの表板１および裏板２の双方に自由端片２１が得られるようにしているが、仮想線や破線で示すように表板１および裏板２間の連結板３の途中から突出したものとしても、一方の中空形材１１の接合端部１１ａの表板１および裏板２に自由端片２１が得られているので、嵌合部１８、１９での嵌合を困難にすることはない。また、仮想線で示すような位置の連結板３を組み合わせ突っ張り部１５と併せても、２つの連結板３が隣接場合よりは局部的な高剛性化は軽減されるし、例え、それが有益でなく、問題になる程度の局部的な高剛性部をなす場合はそのような問題にならない位置にある破線や実線で示すような摩擦接合位置から適度に離れた連結板３から他方側突っ張り部１５ｂを延ばすなどすれば対応できる。   On the other hand, in the example shown in FIG. 5, the other-side protruding portion 15 b provided on the other hollow shape member 12 protrudes from one of the front plate 1 and the back plate 2, in a specific example, from the back surface of the front plate 1 in a cross-sectional shape. The free end piece 21 is obtained on both the front plate 1 and the back plate 2 of the joint end 12a of the other hollow shape member 12 by forming as a part that has been formed as shown by an imaginary line or a broken line. Even if it protrudes from the middle of the connecting plate 3 between the front plate 1 and the back plate 2, the free end piece 21 is obtained on the front plate 1 and the back plate 2 of the joining end portion 11 a of one hollow shape member 11. Therefore, the fitting at the fitting portions 18 and 19 is not difficult. Further, even when the connecting plate 3 at the position shown by the phantom line is combined with the combined stretch portion 15, the local high rigidity is reduced as compared with the case where the two connecting plates 3 are adjacent to each other, and for example, it is useful. In the case of forming a locally high-rigidity part that is not a problem, the other side of the connecting plate 3 that is moderately separated from the friction joining position as indicated by a broken line or a solid line that does not cause such a problem This can be dealt with by extending 15b.
