〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.
FIGS. 1 (A), (B), and (C) are explanatory views showing a main part of a column building device. FIG. 1 (A) is a perspective view thereof, FIG. 1 (B) is a schematic front view thereof, and FIG. 1 (C) is a sectional view showing a connection state between columns. Here, reference numeral 1 is a column erection device, and this column erection device 1 is provided between an existing column 2 made of H-section steel and a new column 3 also made of H-section steel to be constructed. Angle adjustment device 4 installed
And an angle detector 5 previously attached to the new pillar 3,
In order to set the new column 3 vertically, the control device 6 controls the operation amount of the angle adjusting device 4 based on the detection signal of the angle detector 5.

Here, the existing pillar 2 is preliminarily vertically attached, for example, by fastening the underside of this pillar to another pillar or to an anchor bolt (not shown) embedded in a base (not shown) as a base joint portion with a nut. It is fixed to. Then, a new lower side of the pillar 3 is placed and mounted on the upper side of the pillar 2. As shown in FIG. 1 (C), the mounting state is such that a joining plate 7 for joining these to the upper side of the existing pillar 2 and the new pillar 3 is applied, and here, these are manually tightened with bolts and nuts. Temporarily tighten the two pillars. Especially for the existing pillar 2 on the lower side,
As shown in FIG. 1 (C), the new column 3 is fixed by hand-tightening with a high tension bolt through the joining plate 7 at one end of the H-shape, and this is used as a fulcrum S for the new column 3. It means that the pillar 3 is temporarily fixed to the existing pillar 2 so as to be movable in the inclination direction.

The existing columns 2 and the new columns 3 are made of steel columns in this embodiment, but may be made of wood or other members in place of them. As the angle adjusting device 4, here, two hydraulic jacks 4a and 4b (hereinafter simply referred to as jacks) using hydraulic pressure are used. This jack 4a, 4
Although b uses hydraulic pressure as its operating force, it may be gas pressure.

The jacks 4a and 4b are arranged so that the fulcrum, the jacks 4a, and the jacks 4b respectively form the vertices of a triangle when viewed from the horizontal plane, and the two directions in the right angle direction on the horizontal plane,
The tilt angle with respect to the vertical direction is adjusted, and the directions perpendicular to each other on the horizontal plane are assumed to be the X direction and the Y direction here (see FIG. 1 (C)). The jacks 4a, 4b are provided with operating rods 4c, 4b. These operating rods 4c and 4d are respectively on the side surfaces of the new pillar 3 and the jacks 4a and 4b.
The main body is fixed to the side surface of the existing pillar 2, and as a result, the jacks 4a and 4b are attached by being bridged between the upper and lower pillars 2 and 3. Therefore, the inclination angle of the new column 3 with respect to the existing vertical column 2 is adjusted according to the operation amount of the operating rods 4c, 4d. At first, the new pillar 3 is fixed by bolts etc. by hand, so the jack 4
It can be adjusted to a desired angle by a and 4b. The angle detector 5 is composed of a vertical sensor 5a that detects the X and Y directions here. The vertical sensor 5a is attached to a new column 3, and is composed of, for example, a rotary encoder and a weight, and the vertical sensor 5a is responsive to the tilt angle of the new column 3 in the X and Y directions from the vertical direction according to the rotation amount of the weight. It also generates detection signals in the X and Y2 directions, respectively. The control device 6 operates the angle adjusting device 4 according to the detection signal of the angle detector 5 which generates a detection signal corresponding to the inclination angle of the new column 3 from the predetermined reference position, and the operating rod thereof. By controlling the operation amounts of 4c and 4d, the control for vertically setting the new column 3 is performed.

The control device 6 includes two hydraulic pumps P ₁ and P ₂ , motors M ₁ and M ₂ for driving the hydraulic pumps P ₁ and P ₂ , and motors M ₁ and M ₂ and a hydraulic valve (first valve). (See Fig. 2) Controller 6a for controlling
Is equipped with. Where hydraulic pumps P ₁ and P ₂ and jack 4
Between a and 4b, a tube for inputting / outputting liquid such as oil
8a, 8b, 8c and 8d are connected. Controller 6a and vertical sensor 5
A lead wire 9 for sending a detection signal is connected between a and a. The controller 6a has a built-in circuit (not shown) that sounds a buzzer when the signal from the angle detector 5 reaches the vertical angle position.

When the new pillar 3 is inclined with respect to the vertical direction with respect to the existing pillar 2, the vertical sensor 5a supplies a detection signal corresponding to the amount to the controller 6a of the control device 6. To be done.
Here, the control device 6 drives the accommodated motors M ₁ and M ₂ to actuate the hydraulic pumps P ₁ and P ₂ in response to the detection signal to actuate the rods 4c and 4d of the jacks 4a and 4b. Is moved up and down to adjust the angle of the new column 3 to a position perpendicular to the direction opposite to its inclination. Ie new pillar 3
Of the jack 4a, 4b is first adjusted by, for example, the jack 4a, and the angle of inclination is detected by the angle detector 5, and again according to the detection signal (for example, the detection signal in the X direction at first). Then, the jack 4a is actuated to correct the inclination of the column 3 which is temporarily installed. That is, a certain direction (for example, the X direction at first) is first constructed, and then, in the direction perpendicular to this direction (the next Y direction), the jack 4b is operated and the same procedure is performed according to the detection signal in the Y direction. New pillar 3
The inclination of was corrected, this was erected, and it returned to the X direction again and adjusted the amount distorted by the erection work in the Y direction,
Also, return to the adjustment in the Y direction. By repeating this several times, the new pillar 3 is set vertically.
In this way, when the new pillar 3 is set in the vertical position in each of the X and Y directions, the detection amount of the vertical sensor becomes X,
Each time it becomes "0" in the Y direction, the operation of the control device 6 ends. At this time, the controller 6a sounds a buzzer at each vertical position in the X and Y directions to notify that it has been installed vertically. In this way, the new pillar 3 which is made vertical in each direction is then finally tightened and fixed via the joining plate 7. Thus, the new pillar 3 is erected in a vertical state with respect to the existing pillar 2, and is joined and built.
