Description

{INDEPENDENCE SUPPORTING PILLAR STRUCTURE}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an independent load supporting column structure, and more particularly, to an independent load supporting column structure for supporting a structure composed of a plurality of layers by constituting a plurality of unit column member bundles.

The column members of the multi-layer structure support the cumulative load from the upper layer toward the lower layer, so that the vertical load supported by the lower layer becomes larger in the case of a high-rise building.

Therefore, the column member used in the multi-layer structure is a member that transmits the load of each layer to be laminated, and the member becomes larger as the number of layers increases. That is, since the load of the lowermost pillar member increases in proportion to the number of laminated layers (N layer), the member N times larger than the uppermost pillar member is used.

Conventionally, as a method for solving such a problem, there is a method of increasing the thickness of the H-shaped steel. In other words, it is a method to increase the thickness of the flange and the web which form the H-shaped steel to support the accumulated load toward the lower layer of the building. Such a method can solve an increase in the area of the column member.

However, when a column having the same cross section to the upper layer is used to support the accumulated load on the lower layer, the cross-sectional area of the upper-layer column is unnecessarily increased, and the material used for the column member may be wasted.

In addition, the size of the cross section of the pillar member is significantly increased in the lower layer, thereby reducing the actual use area of the multi-layer structure.

The present invention is realized by recognizing at least one of the requirements or problems generated in the conventional column structure.
