【考案の詳細な説明】
本考案は特に車体のスポット溶接部分などに好適な金属
板の重ね合せ結合構造に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a metal plate overlapping joint structure particularly suitable for spot welding parts of vehicle bodies.
通常の車体では金属板相互の結合が突出長さ１０〜２０
ＷＬｒＬ程度のフランジで互いに重ね合され、スポット
溶接されている。In a normal car body, the metal plates are connected to each other with a protruding length of 10 to 20 mm.
They are overlapped with each other with flanges of about WLrL and spot welded.
スポット溶接点の間隔は３０〜５０ｍｍ程度であり、そ
の間に溶接されないにもかかわらず、２枚のフランジが
連続して重ね合されている。The spacing between the spot welding points is approximately 30 to 50 mm, and the two flanges are continuously overlapped even though no welding is performed between them.

相互に容易に変形されて確実な溶接が得られるようにし
たものが提案されている。Conventionally, as shown in Japanese Utility Model Publication No. 45-25237, a metal plate having a complex three-dimensional shape has been fabricated by providing slits at a predetermined interval in one or both flanges that are overlapped and welded together. A method has been proposed in which the overlapping flanges can be easily formed and the flanges overlapping each other can be easily deformed so that reliable welding can be achieved.

これにより溶接物の軽量化を可能にしたものである。In order to achieve the above object, the structure of the present invention is such that each flange is spot welded at regular intervals in the longitudinal direction.
In the overlapping joint structure of two metal plates, a notch is provided in the flange of at least one metal plate at each spot welding interval, and the width of the notch is approximately the same as the circumferential width of the protrusion to be spot welded. or more, and the protruding piece is joined to the flange of the other metal plate by spot welding,
This makes it possible to reduce the weight of the welded product.
本考案の構成を実施例に基づいて説明すると、第１図は
一般的な重ね合せ継手の実施例を示すものであり、板１
及び２がその端縁部即ちフランジ１ａ、２ａを互いに重
ね合され、重ね合せ部分が長手方向に一定の間隔を存し
て点溶接ないしスポット溶接される。To explain the structure of the present invention based on an example, FIG. 1 shows an example of a general overlap joint, in which a plate 1
and 2 are overlapped with each other at their end edges, that is, the flanges 1a and 2a, and the overlapped portions are spot welded at a constant interval in the longitudinal direction.

形成し、この突片３をＸ印で示すように板１のフランジ
１ａにスポット溶接により結合したものである。According to the present invention, as shown in FIG. 2, trapezoidal notches 4 are provided on the flange 2a of one plate 2 at the same intervals as the spot welding intervals, thereby forming protrusions 3 on the flange 2a. The piece 3 is joined to the flange 1a of the plate 1 by spot welding as shown by the X mark.

折曲げて互いに重ね合せ、一方のフランジ２ａについて
前述の実施例の場合と同様に切欠４を設け、突片３をフ
ランジ１ａにスポット溶接するものである。In the case shown in Fig. 3.4, the flanges 1a and 2a are bent at approximately right angles and overlapped with each other so that the surfaces of the plate 1.2 are on the same plane. In the same way as in the above case, a notch 4 is provided and the projecting piece 3 is spot welded to the flange 1a.

に前述の場合と同様に切欠４を設けることによって突片
３を形威し、この突片を板１に重ね合せスポット溶接に
よって結合する。As shown in FIG. 5, when the plate 2 is coupled and supported at a certain angle to the plane of the flat plate 1, the edge of the plate 2 is bent at the required angle to form a flange 2a. This flange 2a
The projecting piece 3 is shaped by providing a notch 4 in the same manner as in the previous case, and this projecting piece is overlapped and joined to the plate 1 by spot welding.
切欠４の幅（すなわちフランジの周方向の寸法）は突片
３の幅とほぼ同等にかつラック状に形成することが好ま
しい。It is preferable that the width of the notch 4 (that is, the dimension in the circumferential direction of the flange) is approximately the same as the width of the protruding piece 3, and that it is formed into a rack shape.
しかし、スポット溶接間隔が大きい場合には、切欠４の
幅を突片３の幅よりも広くしても差支えない。However, if the spot welding interval is large, the width of the notch 4 may be made wider than the width of the protruding piece 3.
本考案は上述のように、互いに重ね合されるフランジの
少なくとも一方について、フランジに切欠を設け、残る
突片を他方のフランジにスポット溶接によって結合した
ものであるから、切欠４の幅が突片３の幅と等しい場合
には、従来のようにフランジが全面で重ね合されている
溶接継手に比べて約２５φ程度の重量軽減を図ることが
できる。As described above, in the present invention, a notch is provided in at least one of the flanges stacked on top of each other, and the remaining protrusion is joined to the other flange by spot welding, so that the width of the notch 4 is If the width is equal to No. 3, the weight can be reduced by about 25φ compared to a conventional welded joint in which the flanges are overlapped on the entire surface.
車体の組立て部分ではほとんど壁面材相互の結合や、壁
面に対する付属部品の結合が、スポット溶接によって行
われている現状からして、本考案のような重ね合せ結合
構造とすれば、車体の軽量化に役立つ。Given the current situation where almost all wall materials are joined to each other and accessory parts are joined to the wall surface by spot welding in the assembled parts of the car body, the overlapping joint structure of this invention can reduce the weight of the car body. useful for.
特に第３図に示す場合のように、板１．２が互いに同一
平面内で連続するように接合する場合には、フランジ１
ａ、２ａの両方に切欠４を設けても差し支えないので、
この場合はさらに重量の軽減に役立つ。In particular, when the plates 1.2 are joined in succession in the same plane, as in the case shown in FIG.
It is okay to provide notches 4 in both a and 2a, so
In this case, it helps to further reduce the weight.
