Description
【考案の詳細な説明】
本考案は自動車の車体構造部材等として用いられるフレ
ームの接続構造に関するものである。[Detailed Description of the Invention] The present invention relates to a frame connection structure used as a structural member of an automobile body.
自動車の車体構造部材として略コ字状断面の両端縁を外
方に屈曲させてフランジ部を形成したハツト形状断面の
フレームが一般に用いられている。2. Description of the Related Art A frame having a substantially U-shaped cross section and having a flange portion formed by bending both ends of a substantially U-shaped cross section outward is generally used as a body structural member of an automobile.
このようなハツト形状断面のフレーム同志を、強度を低
下させることなく結合固定することはなかなか厄介で、
手数のかかるものである（実開昭５５−２５５８３号公
報、実開昭５５−２５５８５号公報参照）。It is quite difficult to connect and fix frames with such a hat-shaped cross section together without reducing their strength.
This method is time-consuming (see Japanese Utility Model Application No. 55-25583 and Japanese Utility Model Application No. 55-25585).

。FIG. 1 shows the structure of the joining ends of the frames to be joined. At the end of the frame 1, which has a hat-shaped cross section and has a bottom part 11, both side parts 12.13 and flange parts 14.15, a bottom part A notch 16 is formed over a predetermined range 1 in the longitudinal direction from the end, from the center of the 11 to the side surface 13 on one side and the flange 15, and the tip edge of the side surface 13 on the notched side is An inwardly projecting wall 13a is formed by bending the frame 1 so as to be perpendicular to the longitudinal direction of the frame 1.
上記切欠き部１６が設けられていない側の底面部及びフ
ランジ部にはほぼ板厚程度の段差部１１ａ及び１４ａが
形成されている。Step portions 11a and 14a having approximately the thickness of a plate are formed on the bottom surface portion and flange portion on the side where the notch portion 16 is not provided.
上記フレーム１に接続固定されるべきフレーム１′も上
記フレーム１と全く同じ構造となっており、フレーム１
と同じ部分には該当符号にダッシュを附して示している
。The frame 1' to be connected and fixed to the frame 1 has exactly the same structure as the frame 1.
The same parts are indicated by adding a dash to the corresponding code.

が完了する。The frames 1, 1' are arranged so that the side surface 13.13' provided with the notch 16 is inside the other side surface 12.12' of the other side, and the stepped portions 11a, ila' of the bottom surface are Fit it so that it is on the outside (lower side) of the bottom surface parts 11', 11 of the other side, and the stepped parts 14a, 14a' of the flange parts 14.14' are on the lower side of the other side flange parts 15', 15, and then With the protruding walls 13a and 13a' abutting each other, as shown in FIG. 2, the joint portions of both frames 1, 1' are fixed by spot welding, and the connection of both frames 1.1' is completed.
このような結合構造をもった本考案によれば両フレーム
１，１′の結合に際し、結合端部を嵌め合せるときその
嵌め合せ深さは内方突出壁１３ａ、１３ａ’により位置
決めされるので結合作業の著しい簡易化をもたらし得る
と同時に、両フレーム１，１′の底面部９両側面部及び

ものである。According to the present invention having such a joining structure, when the two frames 1 and 1' are joined, the depth of the fitting is determined by the inwardly protruding walls 13a and 13a' when the joining ends are fitted together, so that the joining is prevented. This can greatly simplify the work, and at the same time, in addition to mutually joining and fixing the bottom part 9 both side parts and the flange part of both frames 1 and 1', the inwardly protruding wall 13a,
By joining and fixing 13a' (fixing by spot welding or the like), the inwardly protruding walls 13a, 13a' function as joint plates, and the torsional rigidity can be greatly improved.
