Further, in the wall structure according to the present invention, the upper fixing portion, the lower fixing portion, and the intermediate contact portion are all located on the same side of the base material on any one side in the wall thickness direction. It may be arranged.
With such a configuration, the straightening column can be easily installed because the work is performed from only one side in the wall thickness direction with respect to the base material.
In addition, when the wall is warped and a straightening column is installed as a repair work to correct the warp, the straightening column is installed from only one side of the wall thickness direction with respect to the base material. Therefore, the straightening column can be installed by removing only one of the pair of plate materials or forming an opening in only one of the pair of plate materials.
As a result, after installing the straightening column, the work of installing the removed plate material or a plate material in place of the removed plate material, or closing the opening formed in the plate material may be performed on only one plate material of the pair of plate materials. Therefore, even in the case of wall repair work, the straightening pillar can be easily installed.

Further, in the wall structure according to the present invention, the intermediate contact portion may be in contact with the base material via packing.
With such a configuration, the magnitude of the force received by the base material from the intermediate contact portion can be adjusted by adjusting the thickness dimension of the packing.
Further, when the base material is pressed from the intermediate contact portion, it is possible to prevent the base material from being damaged.

Further, in the wall structure according to the present invention, the straightening column has a column portion extending in the vertical direction, and the intermediate contact portion is joined to the column portion so as to project from the side surface of the column portion, and the column is formed. The portion may be joined with an anti-rotation portion that protrudes in the direction opposite to the direction in which the intermediate contact portion protrudes and comes into contact with a member constituting the wall portion.
With such a configuration, the straightening column is prevented from rotating around the axis of the column portion due to the reaction force from the base material, and the intermediate contact portion is in contact with the base material or the intermediate contact portion. Can maintain the state of pressing the base material.

Further, in the wall structure according to the present invention, the rotation prevention portion may be in contact with a member constituting the wall portion via packing.
With such a configuration, the rotation prevention portion can be reliably brought into contact with the member constituting the wall portion by adjusting the thickness dimension of the packing.
Further, when the member constituting the wall portion is pressed from the rotation prevention portion, it is possible to prevent the member constituting the wall portion from being damaged.
