Abstract

PURPOSE: To facilitate operations on the dislocation adjustment and inclination remedy of a column by providing a column plumbing jig clamped to a lower column upper part, a dislocation adjusting bolt, an inclination remedial bolt of a column horizontally held by the upper column, and a plumbing arm respectively. CONSTITUTION: Each mounting piece 2 is clamped to both front sides and the back inside of a lower column 1, while column plumbing jigs 3 are clamped to the pieces 2, and each adjusting bolt 6 is screwed in these jigs 3. Next, each base of two plumbing arms 7 is connected to the jigs 3 via a universal joint 8 at a position corresponding to both sides of a lower end corner part of an upper column 5. Successively these arms 7 are made to advance or retreat to or from the jigs 3 with the bolts 6, imparting a reaction to the piece 2, and a horizontal position of the column 5 is adjusted relatively with the column 1. When a column inclination remedial bolt 10 is rotated, the arms 7 rise or fall due to separation or access of both c.w. and c.c.w. rotational nuts 11a and 11b with each other, whereby the column 5 moves up and down relatively with the column 1, and thus any inclination in the column 5 is remedied in this way.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a column installation adjusting device for a structure, and more particularly to a column installation adjusting device for an existing steel column in a steel building construction.

[0002]

2. Description of the Related Art In recent years, a method for adjusting the installation of a steel column without using a wire rope has been developed and implemented. One of the methods is to attach a guide for the upper pillar to the upper part of the lower pillar in advance, and use the guide as a reaction force to adjust the erection of the upper pillar when the pillar is connected. Pieces are provided on the upper and lower pillars, and turnbuckle type bolts are connected between the pieces to adjust the installation.

[0003]

However, in the case of the former, it is necessary to construct the guide itself with a height of about 600 mm, and the manufacturing cost becomes considerably large as compared with the conventional pillar erection piece. There was a cost drawback.

In the latter case, since the pillar itself is pushed up by the turnbuckle type bolt, it is difficult to adjust the installation of the pillar when the weight of the pillar is large.
There was a drawback that adjustment could not be done unless the upper crane was responsible for the column load to some extent.

The present invention is intended to eliminate the above drawbacks.

[0006]

SUMMARY OF THE INVENTION A structure column-installation adjusting device of the present invention comprises a column-installation jig fixed to an upper part of a lower column, and its tip is in contact with both side surfaces of a lower corner of the upper column. As described above, a misalignment adjusting bolt screwed in the jig so as to be capable of advancing and retracting in the horizontal direction, and a post straightening bolt that is horizontally held by an upper post and has right and left screws respectively on left and right parts,
A nut screwed to each of the right-hand screw and the left-hand screw, and an erection arm pivotally supported on the nut so that the upper end thereof is rotatable and the lower end is pivotally and tiltably supported on the jig. It is characterized in that the misalignment can be adjusted by rotating the misalignment adjusting bolt, and the four sides of the pillar can be moved up and down to correct the inclination by rotating the tilt correcting bolt of the pillar. To do.

[0007]

Embodiments of the present invention will be described below with reference to the drawings.

In the present invention, as shown in FIGS. 1 and 2, mounting pieces 2 are fixed to both front and rear sides of the lower pillar 1 by welding, and a pillar-installing jig extending upward to the mounting piece 2 is installed. The tool 3 is fixed by the fixing bolt 4.

Adjustment jigs 6 for adjusting the misalignment of the upper and lower pillars are horizontally screwed onto the jigs 3 so that the tips of the jigs 3 are in contact with both side surfaces of the lower end corners of the upper pillar 5.

Further, as shown in FIG. 3 and FIG.
The base portion of the building arm 7 is connected to the jig 3 via the universal joint 8 at positions corresponding to both sides of the lower end corner portion.

Further, a jack mounting block 9 is fixed to the center of the side surface of the upper pillar 5 at a portion slightly above the lower end thereof, and right and left screws 10a and 10b are formed on the left and right portions, respectively, to correct the inclination of the pillar. 10 is provided so as to horizontally penetrate the jack mounting block 9, and a forward rotation nut 11a and a reverse rotation nut 11b are screwed into the right-hand screw 10a and the left-hand screw 10b, respectively. The upper end of the building arm 7 at the corresponding position is rotatably supported by a pin 12.

The universal joint 8 has a joint block 8a rotatably supported by a pin 13 on a side wall 3a of a pillar erection jig 3 as shown in FIGS.
The joint block 8a is constituted by a shaft 8b provided so as to extend in a direction perpendicular to the rotation axis of the joint block 8a. The base of the construction arm 7 is rotatably supported on the shaft 8b. To do.

Since the structure column installation adjusting device of the present invention has the above-mentioned structure, as shown in FIGS. 7 and 8, the horizontal deviation of the upper and lower columns is adjusted, that is, the misalignment is adjusted. In order to carry out the above, the adjusting bolt 6 is turned to move it back and forth with respect to the jig 3, and thereby the reaction force is applied to the mounting piece 2 fixed to the lower pillar 1 to make the horizontal position of the upper pillar 5 relative to the lower pillar 1. Adjust.

When the inclination of the upper column 5 with respect to the lower column 1 is to be corrected, if the column inclination correcting bolt 10 is rotated, the nut 11 screwed to the bolt 11 depending on the rotation direction.
As a and 11b come apart from each other or come close to each other, as a result, the building arm 7 rises and falls, and the upper column 5 moves up and down relatively to the lower column 1.

Therefore, if the above operation is performed on at least two of the four columns, the verticality of the upper column 5 can be finely adjusted.

Further, if the above-mentioned operation is carried out on all the surfaces of the pillar 4, it becomes possible to finely adjust the top end level of the upper pillar 5.

When the straightening bolts 10 on one surface of the pillar are rotated to raise the one surface of the pillar, if the building arms 7 on both sides are fixed, the building arms are fixed. There is a risk that the lifting action will be suppressed by the resistance of 7, but this is to make the pin joint part of the building arm 7 slightly loose, tolerable to a certain length against the pulling force, and not to resist You can deal with it by leaving it.

[0018]

As described above, according to the structure column adjusting device of the present invention, it is possible to adjust the misalignment of the upper and lower columns and correct the inclination very easily and easily. Since the column is raised by rotating the column straightening bolt 10 and horizontally moving the nuts 11a and 11b screwed thereto, when the upper column 5 is lifted by, for example, 5 mm, the horizontal movement of the nut is performed. This can be achieved by setting the distance to, for example, 15 mm, and there is a great advantage that the required torque can be reduced to about 1/3 as compared with the case where the upper column 5 is directly lifted.
