JPS63217212A - Automatic detector for perpendicularity - Google Patents

Abstract

PURPOSE:To detect perpendicularity speedily through easy operation by driving and rotating an adjusting screw which engages with a telescope base threadably by a servo-motor and generating a signal for servo-motor driving with an inclination signal from a level on the telescope base. CONSTITUTION:An automatic perpendicularity detector 10 is fitted to a base or existent lower-layer steel column 11 and a fixation base 1 is fixed. A target 13, on the other hand, is fitted to the upper part of another steel column 12 built in the column 11. Further, the center position of the vertical cylinder body 5a of the telescope 5 of the device 10 and the position of the collimation point of the target 13 are set to specific positions of the column 11 and 12, e.g. at the same distance from the center points. Then, a perpendicularity correction unit 9 receives inclination signals (a) from levels 8 and 8 to generate a pulse (b) and the servo-motor 2 operates according to the signal to adjust the telescope base 4 horizontal, whose accurate perpendicularity is calculated. Here, the column 12 is adjusted through an ocular 7 so that the collimation point of the target 13 meets a collimation point, thereby obtaining the perpendicularity.

[Detailed Description of the Invention] [Industrial Application Field 1] The present invention relates to the construction of construction materials such as steel frames and curtain walls;
Pile driving, installation of sliding 7-frame and other formwork,
This invention relates to an automatic verticality detection device for earthworks, etc.

[Prior art and its problems 1 In the United States, for example, as a construction method for steel-frame columns, as shown in Fig. 3, a transillar} T is installed in the X direction and Y direction of the steel column S under construction, respectively. The verticality of the steel column S was detected by visually observing the inclination of the steel column S in both directions.

However, such a method using transshift requires: (a) Two transshifts are required, which requires additional equipment.

(b) Two observers are also required for transshifting, which increases the labor cost.

(c) It is necessary to install the transit at a considerable distance from the steel column, making it impossible to install the transit, especially if the surrounding area is narrow.

(d) Installation of the trans shift is complicated and requires skill, and the verticality of the F run shift itself is likely to be disturbed.

(e)) When observing by installing Runshift inside a building,
If the building is subject to vibration or shaking, transshift measurements may be inaccurate or impossible.

There were problems such as.

Conventionally, as shown in Fig. 4, there is also a method of detecting verticality by hanging a plumb swing 1) W from the top of a steel column S and measuring its distance from the steel column S using a ruler M at the bottom. Ta.

However, this method using a plumb bob is particularly difficult when the wind speed is 3 m
/sec, it becomes impossible to carry out the work, and there are problems such as the work is greatly restricted due to weather conditions and the construction period is hindered.

Furthermore, as shown in FIG. There was a device that detected the verticality of

However, this vertical sensor method also has (a)
A person had to visually orient the telescope in the X and Y directions and align it with the center of the tarded, which was a time-consuming task.

(b) Only the inclination is detected, and the absolute amount of displacement is not detected.

There were problems such as.

It is characterized by being configured as follows.

[Embodiment 1] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a fixed base, which is attached and fixed as appropriate to materials that require verticality, such as construction materials, piles, formwork, and retaining walls.

Three servo motors 2 are arranged on the fixed base 1, each r14! The jk screw 3 is rotated by the required amount in the left and right rotational directions.

These adjustment screws 3 are screwed together to support the telescope base 4 at three points.

Reference numeral 5 denotes a telescope, which is configured in an L-shape in which a vertical cylinder 5a and a horizontal cylinder 5b are orthogonal to each other, and a reflection fi6 is housed within the bent portion at an inclination angle of 45°. .

7 is a #:1llll lens.

8 is a spirit level, which is arranged at 2@ in mutually orthogonal directions (X, Y directions).

Both of these spirit levels 8, 8 are located at the
, the tilt state in the Y direction is electrically measured, and the tilt signal a is input to the verticality correction unit 9.

The verticality correction unit 9 calculates a correction value for determining the horizontality of the telescope base 4, that is, the verticality of the telescope 5, based on the two tilt signals a, and generates a servo motor driving pulse signal S.

The servo motor 3 is actuated by a servo drive pulse signal from the verticality correction unit 9 to rotate the adjustment screw 3 and give accurate verticality to the telescope 5.

Since the device of this embodiment is configured as described above, when handling it, as illustrated in PIS 2, the verticality automatic detection device W is attached to the foundation or existing lower steel column 11.

The device shown in FIG. #42 has a cover, but essentially fixes the fixed base 1 shown in FIG. 1 to the steel column 11.

On the other hand, a tarded 13 is attached to the upper part of another steel column 12 to be erected on the steel column 11.

The center position of the vertical cylinder 5a of the telescope 5 and the position of the reference point of the tarded 13 of the automatic verticality detection device 10 are as follows:
The steel columns 11 and 12 are set at specific positions, for example, at the same distance from the center line.

As described above, the verticality automatic detection device 10 and the tarded 1
When setting 3 is completed, the verticality correction unit 9 receives the tilt signal a from the spirit levels 8, 8, and emits a pulse signal.Based on this, the servo motor 2 operates to adjust the telescope base 4 horizontally. , As a result, accurate verticality of the telescope 5 is obtained.

In this state, look through the eyepiece lens 7 of the telescope 5, or move the steel column 12 so that the reference point of the tarded 13 coincides with the reference point I11! I to find the verticality.
