Description of the Related Art As a vertical frame member a having a function as a pillar, for example, as shown in FIG. 18, a metal plate is provided along a longitudinal direction as a vertical frame member a of a frame such as an outer wall panel used for a prefabricated building or the like. In some cases, a building frame member b having an H-shaped cross section is bent.

Since the work of notching the notch portion d as a space for screwing the n to the screw shaft g is also required,
This has led to a decline in productivity.

どの構造上の弊害が生じる危険性がある。Further, since the connecting members such as the screw shaft g and the nut n are all separate from the building frame member b, the connection strength with other members, here, the supporting bracket e becomes unstable. The permissible proof strength of the connection portion with respect to a force from a direction substantially perpendicular to the longitudinal direction of the building frame member b, the limit value of the connection strength is reduced, and when an instantaneous impact force particularly during an earthquake or the like acts, There is a risk that a structural adverse effect may occur, such as the mounting plate c, and eventually the architectural frame member b moving relative to the connection tool or the support fitting e.

も向上する。The architectural frame member composed of one layer of metal plate has a lower rigidity than that of the present embodiment, and
Because the holding strength of the book is also limited, it is conceivable to design special special hardware for joining and to join the ends, but because the number of special hardware increases, workability deteriorates and structural It becomes complicated. On the other hand, in the present embodiment, as described above, the main body 5 is formed of the metal plate 2 having a plurality of layers (double layers), and the rigidity, bending strength, and buckling strength are increased, and the holding strength of one fixing tool is increased. Because it is also large, there is no need to use special hardware for joining, and the structure can be streamlined and the workability can be improved.

Since the screw hole 9 is previously formed between the two at a factory or the like,
When the screw shaft 36 is screwed, the force of the connection portion is directly supported by the metal plate 2 itself constituting the building frame member 1, and the connection strength with another member, in this example, the support fitting 34 is reduced. It is reinforced and stabilized, it can increase the resistance to impact force in the event of an earthquake and the like, and can prevent the adverse effects on the structure without impairing the workability and cost performance. There is no need to attach a connection tool such as this, and productivity can be increased.
