3. The movable mechanism has a shaft having a screw portion at one end connected to the clamping portion and screwed into the base portion, and an operating portion for rotating the screw portion relative to the base portion. The segmented column guide according to claim 2, wherein the clamping portion approaches or moves away from the guide pin by operating the operating portion to rotate the shaft relative to the base portion.

4. The segmented column guide according to claim 3, wherein the gripping portion also serves as the operating portion.

5. The gripping portion extends in a direction perpendicular to the extending direction of the guide pin, The segmented column guide according to claim 4, which is located on the outside of the second flange portion when the second flange portion is being clamped.

6. The segmented column guide according to claim 1, wherein the outer circumferential surface of the base end of the guide pin, which is located inside the second screw insertion hole when inserted into the second screw insertion hole, has irregularities formed on it.

7. The segmented column guide according to claim 1, wherein the guide pin has a tapered tip.

8. The segmented column guide according to claim 1, wherein the guide pin is detachably attached to the base.

9. A method for guiding a divided column, comprising guiding a second flange portion, which is provided on the lower end of an upper divided column suspended above the lower divided column and has a plurality of second screw insertion holes formed along the circumferential direction, to a first flange portion provided on the upper end of a lower divided column erected on the ground and having a plurality of first screw insertion holes formed along the circumferential direction, The base and, A guide pin protruding from the base and inserted into the second screw insertion hole, Using a segmented column guide having a gripping portion provided at the base, Insert the guide pin through the second screw insertion hole, The gripping portion is grasped and the second flange portion is displaced, A method for guiding a divided column, characterized by inserting the guide pin into the first screw insertion hole.

10. Using the pair of first and second segmented column guides, which are the segmented column guides, The guide pin of the first segmented column guide is inserted through one of the two second screw insertion holes, which are located on opposite sides of each other, and the guide pin of the second segmented column guide is inserted through the other. With the upper segment column inclined with respect to the vertical, the gripping portions of the first segment column guide and the second segment column guide are gripped and the second flange portion is displaced, such that the second screw insertion hole through which the guide pin of the first segment column guide is inserted is located lower than the second screw insertion hole through which the guide pin of the second segment column guide is inserted. The method for guiding a divided column according to claim 9, wherein after inserting the guide pin of the first divided column guide into a predetermined first screw insertion hole, the inclination of the upper divided column is reduced, and the guide pin of the second divided column guide is inserted into another first screw insertion hole.

11. The method for guiding a divided column according to claim 10, wherein the guide pin of the first divided column guide is longer than the guide pin of the second divided column guide.
