る。Generally, a galvanized steel sheet is used as a material for the plate member, but when the plate member is arc-welded, gas is generated from the zinc material due to welding heat, which easily causes blowholes in the welding line. In order to prevent the occurrence of blow holes, it is effective to provide a gap of about 0.5 mm between both plate members to be overlap-welded and let the generated gas escape to the side opposite to the welded part. When welding the flanges 03 and 04 as shown in FIG. 1 (a), as shown in FIG. 2, the protrusion 06 formed on one flange 03 is brought into contact with the mating flange 04, so that a predetermined distance is provided between them. It has been conventionally proposed to secure the gap g of.

However, a large space is required to dispose this, and the weight becomes heavy. From this point of view, the item (b) is superior.

There is a problem that it is difficult to correctly determine the vertical position of both plate members when connecting 1.02. On the other hand, in (a), vertical positioning can be easily performed by overlapping the flanges with each other, but there is a difficulty in horizontal positioning.

ずしも容易ではない。Further, in (a), by maintaining the gap g between the flanges 03 and 04 at a predetermined value as shown in FIG. 2, it is possible to easily suppress the generation of blow holes, but in (b), In order to provide a predetermined gap evenly in the overlapping portions on both sides, it is not enough to provide the projections as shown in FIG. 2 on the inner surfaces of the side plate portions 01a on both sides of the plate member 01, respectively. Since it is necessary to precisely set the distance between the inner surfaces of 01a and the outer surface of both side plate portions 02a, it is not always easy to take measures against blowholes.

溶着する。The present invention has been made in view of such circumstances, and in the present invention, two plate members formed in a groove shape are connected to each other with their groove-shaped open surfaces. In a structural member having a closed cross-sectional shape formed by welding and facing each other, a flange is formed so as to project along an edge of one side plate portion of each of the two plate members, and both plate members are
The flanges are overlapped with each other and the edge portions of the other side plate are overlapped with each other inside and outside, and the flanges of both plate members cooperate with each other to regulate the relative lateral position of both plate members. Positioning means for
As a result, a predetermined gap is formed between the edge portions of the other side plate portion, and the edge portions are welded by arc welding.

置決めが極めて容易である。In the above structural member according to the present invention, when the two plate members are joined together, the flanges provided on one of the side plate portions are overlapped with each other to determine the vertical position of the two plate members, and the lateral position is determined by the positioning means. Since the directional position is determined, the positioning of both plate members at the time of connection is extremely easy.

ペースでも設置が可能であり、かつ重量も軽減する。Further, the flange is provided only on one side portion of the structural member, and at the other side portion, the edge portions of the side plate portions of both plate members are overlapped with each other inside and outside and welded by arc welding. The width is narrower than that of the conventional structural member in which the flanges are projected on both sides, so that the flange can be installed in a relatively narrow space and the weight is reduced.

なるので、アーク溶接の電流／電圧が安定する。However, since the lateral positions of the plate members are restricted by the positioning means, the overlapping portions of the side plate end edges on the other side are overlapped with each other.
Since the predetermined gap can be formed with high precision, the gap can be precisely set to a value effective for preventing the blowhole, and a good arc weld portion free from the blowhole can be secured. Moreover, since the above-mentioned gap becomes constant along the welding line, the current / voltage of arc welding becomes stable.
