However, in order to securely install the center pillar in the frame of the house, a special tool is used (see PVC pipe and iron pipe fixed to the upper part of Non-Patent Document 1). Therefore, for the cross-sectional shape of the central pillar, a special tool corresponding to one shape was used. Therefore, once the equipment was prepared, the degree of freedom in selecting the center pillar was significantly lost.

For example, if the center pillar is thick, the strength increases, but it becomes difficult to install and the cost increases. On the other hand, if it is thin, the strength is low, but it can be easily installed and the cost can be suppressed. Conventionally, since the cross-sectional shape of the central pillar is fixed, it has been difficult to take measures such as changing the thickness of the central pillar to be installed according to the degree of snowfall. As a result, excessive strength is dealt with, which increases costs and work.

Therefore, an object of the present invention is to provide a pillar or the like that allows the cross-sectional shape of a central pillar to be installed in a house to be selected by using the same tool.

The support portion corresponding to the smallest shape of the lower end of the columnar portion is on the innermost side corresponding to the different shape of the lower end of the columnar portion, and the support portion corresponding to the larger shape of the lower end of the columnar portion is formed. It is on the outside of the support that corresponds to the smaller shape.

The second aspect of the present invention is the support column of the first aspect, and the columnar portion includes an upper columnar portion, a hollow lower cylindrical portion, a lower end side of the upper columnar portion, and the lower cylinder portion. The upper columnar portion is provided with a connecting portion for connecting to the upper end side of the shaped portion, and the cross section of the outer surface of the upper columnar portion is included in the cross section of the inner surface of the lower tubular portion. Part or all of the above can be stored in the hollow space of the lower tubular portion, and when installed in the house, the upper end of the upper columnar portion is inserted into the ceiling installation portion, and the lower tubular portion The lower end is supported by the support portion.

The third aspect of the present invention is the support column of the first or second aspect, and the support portion includes the first support portion that supports the inner surface side corresponding to the small shape of the lower end of the columnar portion, and the support portion. It is a second support portion that supports the outer surface side corresponding to the large shape of the lower end of the columnar portion, and the columnar portion is between the first support portion and the second support portion regardless of whether the lower end has a small shape or a large shape. It is something that can be supported.

The fourth aspect of the present invention is a support column from any one of the first to third aspects, and the support portion supports the outer surface side or the inner surface side of the lower end of the columnar portion on the side surface. The side surface of the support portion is inclined from the outside to the inside if the outer surface is supported, and is inclined from the inside to the outside if the inner surface is supported.

A fifth aspect of the present invention is a method of installing a support column in a house, wherein the support column includes a columnar portion, a ceiling installation portion into which the upper end of the columnar portion is inserted, and a lower end of the columnar portion. The columnar portion is provided with a base portion into which the columnar portion is inserted to support the columnar portion, and the columnar portion includes an upper columnar portion, a hollow lower tubular portion, a lower end side of the upper columnar portion, and an upper end side of the lower tubular portion. The base portion is provided with a plurality of support portions that project to support the inner surface and / or the outer surface of the lower end of the columnar portion, and the plurality of support portions are the lower end portions of the columnar portion. Corresponding to different shapes, the ceiling installation portion is installed in a state where the upper end of the columnar portion is not inserted into the ceiling in the house, and a part of the upper columnar portion is installed in the hollow space of the lower tubular portion.
