[Action]

 Next, the operation (construction and adjustment method) of the present invention will be described.

After the foundation concrete is constructed, a base concrete is usually constructed thereon by using mortar or the like.

When the base concrete thus constructed (hereinafter simply referred to as the “base concrete horizontal surface”) is hardened, the leveling device is installed on the base concrete horizontal surface at the same time as the holes for inserting the anger bolts. Drill a hole for.

[0016] In this case, the horizontal surface of the base concrete is hardened, and it is convenient and convenient that it does not require preparation such as scaffolding and that it can be formed at the same time as the hole for inserting the post-installed anchor bolt.

After the hole is formed, the hole is filled with, for example, an adhesive, and then the inserting cylinder is inserted, and then the collar body is brought into contact with the horizontal surface of the base concrete. As described above, several post-installed anchor bolts are simultaneously inserted (hereinafter the same).

Since the insertion of the leveling device and the post-installed anchor bolts is completed by this, the next leveling device and the rearing device are usually installed at another place through the same operation and procedure as described above. Insert the anchor bolts.

Thereafter, the same operation and procedure are repeated as necessary.

As described above, when the level of the steel column is to be raised through the leveling device inserted, the lock nut is opened and the adjuster bolt is adjusted to determine the position.

Thereafter, the lock nut is tightened to fix the adjuster bolt position. Adjuster bolts as described above and lock nut tightening, etc. provided on each of the other inserted cylinders are also subjected to the same operation and procedure.Adjuster bolts fixed in this position By using, for example, the leveling of each steel column is performed.

If the leveling position cannot be ensured by inserting one insertion cylinder, first insert the square bolt of the insertion cylinder into the hole for inserting the leveling device. After the tubular bodies are integrated by fitting, welding or the like, they are inserted into the holes with an adhesive material or the like, for example.

After that, when the insertion cylinder is held, the lower end of the extension cylinder is fitted into the square bolt of the insertion cylinder, and the extension cylinder is extended to the flange body of the insertion cylinder. Abut the lower end surface of the cylinder.

Then, an adjuster bolt is screwed onto the screw of the extension cylinder. As a result, the insertion of the leveling device is completed, so that the next leveling device is usually installed at another location through the same operation and procedure as described above.

As described above, when the level of the steel frame column is to be raised through the leveling device provided respectively, for example, the lock nut of any adjuster bolt is opened and the adjuster bolt is adjusted. To a predetermined position.

After that, the lock nut is tightened to fix the adjuster bolt position. Further, the same operation and procedure are not performed for the other insertion cylinders, the extension cylinders provided on the insertion cylinders, and the adjuster bolts provided on the extension cylinders. Utilizing the adjuster bolts fixed in this position, for example, the leveling of each steel column is performed.

The handling of the post-installed anchor bolts is the same and will be omitted.
