掛り、コスト高を招く欠点もある。Problems to be Solved by the Invention This girder member A has flat plate portions 11b and 12b of the mounting plate portions 11 and 12.
Is attached to the inner panel or the pillar of the door panel P, but in the girder member A, since the mounting plate portions 11 and 12 are fixed to the main body portion 10 by spot welding, they are impacted and destroyed with a lower strength than the main body portion. In addition, the mounting plate portion 11,
If a load is applied to the flat plate portions 11b and 12b of the twelve fixed to the door inner panel or the pillar, the flat plate portions tend to bend easily, which is not satisfactory as a reinforcing member. Moreover, not only a large number of spot welding points are required to maintain the strength, but also the mounting plate 1
Since 1 and 12 are formed by separate pieces, there is also a drawback that assembly work takes time and costs increase.

でもない。The girder member shown in FIG. 1 is for reinforcing a door panel of an automobile, and can be formed by cold rolling or press forming using a metal steel plate. As the metal steel sheet, it is preferable to use a cold-rolled high-tensile steel material having a tensile strength of about 100 Kg / m 2 , and this steel sheet can maintain the necessary strength and reduce the overall plate thickness and facilitate bending as described later. You will be able to. In the forming, first, as shown in FIG. 2, a flat steel plate is roll-formed in a substantially wavy cross section so that peaks 1a and valleys 1b are alternately arranged over the entire length. In this corrugation, the main body 1 of the girder member can be formed, and the main body 1 may be bent so that the peaks 1a have two or three peaks. After that, each mountain portion 1a is press-molded so as to gradually collapse toward the terminal near the left and right ends. In this depression forming, the flat surface of the mountain portion 1a is bent in the same direction as the valley portion 1b from the plane of the side surface to form the mounting plate portions 2 and 3 for the door panel of the automobile in cooperation with the bottom surface 1b of the valley portion. become able to. At the time of the recess forming, fold so that the bottom surface is aligned with the bottom surface of the valley portion 1b, or, depending on the shape of the door inner panel or pillar, fold until it protrudes from the bottom surface of the valley portion 1b to the rear side. It can also be molded. Also,
In this depression molding, the rising ribs 4 and 5 can be formed between the ribs 1b. The rising ribs 4 and 5 are formed by folding the side faces of the mountain portion 1a in two, and are formed so that the sum of the heights of the two side faces at the end is approximately equal to the height of the mountain portion. It is advisable to fix them by spot welding or the like. Further, in the present embodiment, the case where the adjacent ridges 1a are depressed and formed from the same position in the longitudinal direction has been described, but depending on the shape of the door inner panel or the pillar, the ridges may be formed from different positions in the longitudinal direction. Needless to say.

When the girder member is attached to the door panel, the auxiliary plates 6 and 7 may be fixed to the top surface or the back surface of the mountain portion of the main body portion 1 by spot welding or the like. It can be fixed to the door inner panel or pillar by spot welding or arc welding.

補強桁部材を提供できる。EFFECTS OF THE INVENTION As described above, according to the reinforcing girder member for a door panel of an automobile according to the present invention, since it is formed of one part, it can be manufactured at low cost and can be easily attached. Since there is no such structure and the ribs are reinforced by the rising ribs, the strength of the door panel can be greatly improved. Even when the main body is usually formed from cold-rolled high-strength steel plate, which has poor formability, the mounting plate can be formed by a process that is closer to so-called bending than drawing, so ordinary press processing should be applied. In addition, it is possible to provide a lightweight and high-strength reinforcing girder member.
