The lower end of the pillar is received by the pillar supported by the seat plate, and the inclination of the pillar is corrected by rotating the screw shaft.

[0006]

By the way, in the above column supporting device, three screw shafts for correcting the inclination of the column are screwed upward into the seat frame. Engagement is difficult, rotation of each screw shaft is troublesome, and the inclination of the column cannot be easily adjusted.

[0007] In addition, since the rotation of the three screw shafts pushes up the periphery of the lower surface of the pillar, the pillar is greatly inclined by a slight rotation of the screw shaft, and it is difficult to make fine adjustments.

SUMMARY OF THE INVENTION An object of the present invention is to provide a level adjusting device for a base stand which can finely adjust the inclination of a column and which can be easily adjusted.

[0009]

In order to solve the above problems, the present invention has a pair of side frames on both sides,
An anchor bolt fixed to the foundation, a base mount fixed on the base by a nut screwed into the bolt, and a sill stone fixed on the base mount,
In the level adjusting device of the base gantry at the gate adapted to support the lower end of each of the pair of pillars at both ends of the upper surface of the sill stone, at least four corners of the base gantry with adjusting bolts for level adjustment facing the upper surface of the base. The screwed configuration is adopted.

Here, instead of supporting the pillar with a threshold stone,
At both ends of the sill stone, pillars may be mounted on the base frame, and the pillars may be supported by the pillars.

[0011]

With the above construction, the level of the upper surface of the base can be adjusted by rotating the adjusting bolt and moving the adjusting bolt forward and backward with respect to the base. The inclination can be corrected.
