Description

Description: [Industrial field of use] The present invention relates to a verticality measuring device for a column when assembling a column steel frame.

[Conventional technology]

Normally, bolt joints are often used to construct steel frames, and in that case, the verticality of the columns is corrected by first assembling a certain range of steel members and temporarily tightening them with bolts. Is measured using a surveying instrument such as transit.
If necessary, the wire and turnbuckle are used.

[Problems to be Solved by the Invention]

By the way, in such a conventional method, since the range in which the column is left in the temporarily tightened state is assembled, the assembled column steel frame is not measured while measuring the verticality and correcting the column collapse. There were problems that it was stable and that it could not be applied to all welded joints.

INDUSTRIAL APPLICABILITY The present invention is for solving the above-mentioned problems, and the verticality can be measured at the same time when the column is erected, and as a result, it can be applied to welded joints, which can improve the working efficiency and safety. An object of the present invention is to provide a steel frame verticality measuring device.

[Means for solving the problem]

Therefore, the verticality measuring device of the pillar steel frame of the present invention, the disk-shaped target in which the sensor is arranged concentrically with the center attached to the portion where the pillar steel frame is hung, and the pillar steel frame lower end side same surface, The laser light receiving position of the disc target is provided with two laser oscillators arranged concentrically with the center of the pillar steel frame at intervals of 90 degrees and irradiating the disc target with laser light. The feature is that the verticality of the column steel frame is obtained by.

[Action]

The present invention receives a laser beam from a laser oscillation device installed at a known position at the lower end of the column by a disk-shaped target in which a sensor is arranged concentrically with the center being attached to a portion where the column is suspended, Since the verticality of the pillar is measured by the light receiving position, the verticality of each pillar can be measured at the same time when the pillar is erected. Therefore, it can be applied to welded joints, resulting in improved construction efficiency and safety. It is possible to improve the property.

〔Example〕

 Embodiments will be described below with reference to the drawings.

FIG. 1 is a diagram for explaining one embodiment of the verticality measuring device for a pillar steel frame of the present invention, in which 101 is a laser oscillator and 103
Is a target, 105 is an automatic sling device, 107 is a rope, 10
9 is a pillar member.

In the figure, a pillar member 109 is hung by a rope by an automatic slinging device 105 and hung by a crane robot (not shown) to be joined to a lower pillar. Automatic sling device 10
Reference numeral 5 is a known one, and a pin is remotely inserted into a hole of an ear (not shown) provided at the upper end of the pillar member and is hung by a rope. After inserting this pillar into the lower pillar, it is necessary to correct the collapse of the pillar. Therefore, in this embodiment, the automatic slinging device 105 is provided with a target including a two-dimensional sensor including a photodiode array, for example.
103 is installed, and laser light is emitted from the laser oscillator 101 installed at a known position at the lower end of the pillar member 109. At this time,
Since the light receiving position of the target changes depending on the inclination of the pillar member, the inclination can be measured depending on which position of the sensor receives the light. In this case, by calculating in advance for each sensor how many times the pillar tilts when receiving light, it is possible to immediately detect in which direction and how many times the pillar tilts depending on the light receiving position.

Further, as shown in FIG. 2, the crane 203 is controlled by the control signal obtained by the arithmetic processing by the arithmetic processing control device 201 by the detection signal from the verticality measuring device 207, whereby the inclination of the pillar member is automatically controlled. Fix it. In this way, by calculating the control amount by the arithmetic processing control device from the detected verticality data and controlling the crane, the building of the pillar,
Since the vertical alignment can be automatically performed, it is possible to improve the operation efficiency and the safety.

FIG. 3 is a diagram showing another embodiment of the present invention, in which the same numbers as in FIG. 1 indicate the same contents. Incidentally, 101a, 101b
Is a laser oscillator, 111 is a disk-shaped target, 113 is a hanging wire, 115 is a hook, and 117 is a rope.

In the present embodiment, the target has a disk shape so that it can be applied to a case where the position where the target is mounted is swung, for example, when the target is mounted on a crane hook.

The hook 115 is designed to be able to rotate freely so that abnormal force is not concentrated. If a target as shown in Fig. 1 is attached to this part, the laser light may not hit the target depending on the rotation condition. I will end up. Therefore, a plurality of sensors are arranged concentrically on the disk-shaped turret 111, and the center position of the sensors is attached to the crane hook 115. By doing so, as long as the inclination does not change even if the hook rotates, the same sensor is irradiated with the laser light. On the other hand, on the lower end side of the pillar member, two laser oscillators 10 are arranged at a known position at an angular interval of 90 degrees on a concentric circle with respect to the center of the pillar.
1a and 101b are provided. Therefore, if the pillar is tilted in a certain direction, the light beams of the lasers 101a and 101b will be received by the sensors at different radial positions, and it is possible to know which and how much the lens is tilted by the combination.

〔The invention's effect〕

As described above, according to the present invention, since the verticality detecting device is attached to the crane hook or the automatic slinging device, it is possible to measure the verticality at the same time when the column is installed, and as a result, the column is temporarily Since the verticality is already maintained when fixing, it can also be applied to welded joints. In addition, since the detection signal from the verticality measuring device is arithmetically processed by the arithmetic processing control device and the result is used as the control signal of the crane, the erection of the pillar and the verticality can be automatically performed. It is possible to improve efficiency and safety.
