CONSTITUTION: A pillar in which a reinforcing material comprises a lower column (1), an upper column (2), a coupler (3), and a reinforcing material (4). The reinforcing material reinforces the upper column by being installed inside the upper column. The reinforcing material includes an inner pipe, a flange, and a support. The inner pipe is inserted into the upper column in the axial direction of the upper column. The flange is arranged on the outer circumference of the inner pipe to fix the inner pipe to the inner circumference of the upper column. The support is inserted into between the upper column and the inner pipe. |
