Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a box column mounting structure which has good workability and is low in cost.

[0002]

2. Description of the Related Art Conventionally, box pillars are increasingly used as pillars of buildings instead of steel pillars. As an advantage of applying the box column, since a rigid frame structure can be adopted in both directions, the degree of freedom in planning can be increased when a building is designed and a long span can be achieved.

[0003]

However, since the box column has a closed cross-section with no unevenness on the surface, it is not only a beam, but also a secondary member such as a canopy or a hanging member, and a brace, etc. In order to transfer stress smoothly except for things,
It was necessary to weld the diaphragm within the closed column cross section. Above all, the joining of the secondary member occurs not only in the joint with the beam but also in the middle of the column, so it is necessary to cut the column and weld the diaphragm each time, and it takes time and labor to process and weld. At the same time, the cost was high.

In view of the above circumstances, it is an object of the present invention to provide a box column mounting structure which has good workability and is low in cost.
