[Problems to be solved by the invention]
However, in this case, the joining of the horizontal beam and the vertical beam depends on the deformation by the punch for the protrusion of the joint strip to the expanded part of the expanded notch. Considering the thickness of the material, the above-mentioned deformation of the ridge is a shallow point of about 1 mm or less if it is performed on one side and about 0.5 mm or less if it is performed on both sides. Therefore, the insertion joint by deformation is performed when the point-shaped deformed portion is caught at the edge of the expanded portion in a very shallow state. Insufficient bonding strength cannot be ensured in the body, especially when the deformation position by the punch is out of order, or when the deformation width by the punch is small relative to the size of the spread site. To ensure the bonding strength There is a problem that it becomes impossible to obtain, and further, the notch processing of the expanded notch part becomes complicated, and it is necessary to precisely position the deformation position by the punch, so that there is a problem that the insertion joint is also easily complicated. .

The standing fin 5 and the vertical beam 2 are provided with a pair of joining strips 9 on both sides thereof, and the standing fin 5 and the joining strip 9 are integrated with the horizontal beam 1 and the vertical beam 2 to form the aluminum thin plate. It is formed by a bending polymerization forming material.
[0009]
That is, the horizontal beam 1 of this example is 0.5 mm thick, for example, and the vertical beam 2 is formed by roll forming on a thin aluminum alloy plate of 0.15 mm thickness, for example, to form a roll forming molded outer skin 3. A nozzle is inserted from the unjoined opening of the bent joint immediately before the aluminum sheet is bent and joined at the final stage of roll forming, and a foamable synthetic resin material 4 made of, for example, urethane foam resin is injected and molded. By foam filling in the outer skin 3, this is used as a core of strength elements in the horizontal beam 1 and the vertical beam 2 bonded and cured to the molded outer skin 3.

At this time, the horizontal beam 1 is formed by roll forming the outer shell 3 with the center of one of the opposing surfaces of the upper and lower surfaces as the bent joint, and the standing fin 5 having a thickness of 1 mm is inserted into the vertical beam at the bent joint. 2, roll forming of the molded outer skin 3 is performed with the center of one side surface of the both side surfaces being the same as the bent joint portion, and the joint strips 9 are respectively provided at the bent joint portion and the other side surface center corresponding thereto. The standing fin 5 is formed by roll forming integrally with the molded outer shell 3, and one end of the aluminum thin plate is erected in an up-and-down shape in the form of a goby fold, and the tip thereof is connected to the other end of the aluminum thin plate. Is bent up in the shape of a letter in the molded outer shell 3 and is elastically locked to the locking portion installed to stand upright in the longitudinal direction. smell Both sides of the aluminum thin plate are similarly folded in the left-right direction to form the front and rear ridges 10 each having a thickness of 0.3 mm at intervals of 1 mm corresponding to the thickness of the standing fin 5 and the tip of one side end. The other end is bent elastically with respect to a locking portion which is installed by bending the other end into a letter-like shape within the molded skin 3 to thereby insert a fitting groove 11 having a width of 1 mm between the front and rear protrusions 10. A joint strip 9 having a U-shape or an approximate shape thereof is formed so as to protrude in the entire length in the longitudinal direction, and the joint strip 9 having the same shape is formed on the other side surface so as to project in the longitudinal direction by roll forming. .
