And a joint is formed on the upper end side, and the lower support is composed of a steel pipe pile, a concrete PC pile or an iron pile, and the upper support is composed of a steel pipe pole, a concrete pole or an iron pole.

A standing method for solving the problem is a standing method for standing a plurality of columns in order to suspend a ball-proof net or a tent sheet along a space, and the column is placed on the lower column and the upper column. Select the lower strut made of steel pipe pile, concrete PC pile or iron pile according to the standing condition, and bury the lower end side of the lower strut in the ground and form it on the upper end side of the lower strut The upper strut made of a steel pipe pole, a concrete pole or an iron pole is selected and connected to the connected joint.

Effects and effects of the invention

Next, the operational effects of the column and the column standing method of the present invention will be described.

First, a plurality of support columns of the present invention are erected along the outer periphery of the space, and a ball-proof net or a tent sheet is suspended.

The support column is composed of a lower support column embedded in the ground and an upper support column connected to the lower support column. The lower support column is formed on the upper end side of the lower support column after being fixed by embedding the lower end side of the lower support column in the ground. The upper column is connected to the joint to form the column.

At this time, by dividing the support column into a lower support column and an upper support column according to the road conditions up to the space and the condition of the standing ground, it is possible to improve the work efficiency at the time of transfer and standing of the support column.

Moreover, it can fix to the ground firmly by comprising a lower support | pillar with a steel pipe pile, a concrete PC pile, or an iron pile according to the hardness conditions of the ground.

And the optimal support | pillar according to the height of a support | pillar can be erected by comprising an upper support | pillar with a steel pipe pole, a concrete pole, or an iron pole.

That is, by forming the lower support column with a steel pipe pile, the flange can be formed on the steel pipe to increase the ground contact area, and the burial work can be performed in a narrow place as compared with the concrete PC pile.

Moreover, a high support | pillar can be easily formed by comprising an upper support | pillar with a steel pipe pole.

Moreover, it can be comprised economically compared with the case where a steel pipe is used that an upper support | pillar is comprised with a concrete pole.

Thus, the structure of the support | pillar of this invention can be changed freely, and the optimal support | pillar according to the objective can be erected.

An embodiment of the column and the column standing method of the present invention will be described.
