Description

Description: TECHNICAL FIELD The present invention relates to a method for constructing a building material such as a steel structure, a steel reinforced concrete structure, or a steel tower or a curtain wall.

[Prior Art] Conventionally, for example, as a method of constructing a steel frame, as shown in FIG. 4, a steel column that has been processed with a few layers in a factory as one node is constructed at a construction site such as a tower crane. It is installed by a square machine, and a horizontal member such as a steel beam is laid over it, and each joint is temporarily tightened with 1/5 to 1/3 of the final tightening bolts.
After that, bracing was carried out at the key points of the steel frame with wires to correct the distortion by transit, plumbing, etc., and the main tightening, welding, riveting or bolting was performed.

When building the above-mentioned steel columns, there are guidance workers at the positions of the joints and use the handset, whistle, flag, etc. to signal the operator of the construction machine, and guide using a transceiver or other radio. Was.

[Problems to be Solved by the Invention] However, the guidance of the above-mentioned site worker by hand, whistle, flag, radio, etc. is particularly difficult to delicately guide and requires considerable skill. There was a risk of damage and danger, especially when the wind was strong, it was not possible to do the construction work.

Further, in the above-mentioned conventional erection method, since it is temporarily tightened and then the work is re-distorted, it takes a lot of time and labor to complete the erection, the work efficiency is poor and the construction cost becomes expensive, and the construction period is high. There was a problem that it became longer.

In particular, in the case of a skyscraper, the span adjustment is insufficient, and corrections have been made using large-scale equipment in order to fit within the construction error range.

The present invention has been made in order to solve the above-mentioned conventional problems, and the purpose thereof is to make it possible for an operator of a erection machine to accurately grasp the installed state of a construction material such as a steel column and to remotely Operate quickly and accurately to the prescribed installation position,
By maintaining the erection position and posture of the construction material, temporary tightening and re-distorting work can be omitted and main tightening can be performed directly, reducing the burden on the guide operator and the work process, and significantly reducing the construction cost, It is to provide a construction method of a construction material that can dramatically improve the construction efficiency.

[Means for Solving the Problems] The method of erection of a structure of the present invention provides a vertical point monitoring device including two two-dimensional compensators for automatically adjusting the vertical collimation direction in the XY axis direction and a CCD camera. , Removably attached near the head connection of the existing building material, and hung by a construction machine such as a crane and connected to the above building material near the upper hanging part of another building material, in the center Attach the target with the pinhole opened, capture the pinhole image of the target with the CCD camera and display it on the monitor, while watching the deviation state of the pinhole of the target projected on the monitor, It is characterized in that the construction material is connected vertically by automatic or manual operation.

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

In FIG. 1, reference numeral 1 is a head of a foundation or an existing lower-layer steel column, and another steel column 2 connected thereto is suspended by a building machine (not shown) such as a tower crane or a truck crane. It is embedded.

As shown in FIG. 2, a vertical point monitoring device A is attached to one side of the head of the steel column 1.

The vertical point monitoring device A is mainly composed of a first two-dimensional compensator 3, a second two-dimensional compensator 4, and a CCD camera 5.

The two-dimensional compensators 3 and 4 are for automatically adjusting the vertical collimation directions in the X-axis direction and the Y-axis direction, respectively.

Further, the CCD camera 5 is adapted to electrically detect the collimation point imaged through the optical system.

5'is an eyepiece. Reference numeral 6 is a fixture such as a magnet base or a clamp, which is detachably attached to the steel frame column 1.

The target 7 shown in FIG. 2 has a pinhole 7a at the center.
And light passing through the pinhole 7a and the target 7
The light reflected from the base material can be discriminated, and as shown in FIG. 1, it can be detachably attached to the upper portion of the steel column 2 under construction.

Next, the steel frame construction work by the above-described device will be described.

First, the vertical point monitoring device A and the target 7 are set on the steel columns 1 and 2, respectively. At this time, the light receiving reference position of the vertical point monitoring device A and the pinhole of the target 7
Set so that the position of 7a is at the same position from the reference planes of the two steel columns 1 and 2 to be connected.

When the above preparatory work is completed, the suspension wire 8 is hung on the upper end portion of the steel frame column 2 and moved to a predetermined suspension position by a erection machine such as a crane.

In this case, it is preferable to suspend the steel frame column 2 so as to maintain the vertical state as much as possible.

When the steel column 2 is moved almost directly above the steel column 1 to be connected and is brought into a state close to the connection posture, the image of the target 7 is captured by the vertical sensor A, and the target image received by the CCD camera 5 is As shown in FIG. 3, the image is displayed on the monitor 10 via the image processing device 9, and it is confirmed that the steel column 2 is suspended almost directly above the steel column 1.

Then, the steel column 2 is dropped onto the steel column 1 and the connection work is immediately started.

In the connection work, first, after tightening the bolts in a temporarily tightened state, while watching the collimation point projected on the monitor 10, that is, the deviation state of the pinhole 7a of the target image, the collimation point (pin Correct the steel column 2 vertically so that the rotational runout of the hole 7a) comes to the center of gravity, and then fully tighten it. In this case, an operator near the lower vertical point monitoring device A looks at the monitor and sends a signal to the crane operator.
The monitor may be further placed in the operator's seat, and the operator himself may make corrections while looking directly at the monitor. This correction work may be automatically performed by calculating the barycentric position of the rotational shake of the collimation point by a computer.

In FIG. 3, reference numeral 11 denotes an arithmetic unit such as a personal computer or a pocket computer, which is designed to digitally display the collimation point, that is, the deviation amounts X and Y of the pinhole 7a. ing.

When the connection of the steel frame 2 is completed, the vertical point monitoring device A and the target 7 are removed as necessary, and the next erection work is started.

If a plurality of sets of the vertical point monitoring device A and the target 7 are prepared and the erection work is performed by another set while one set is attached and detached, the efficiency is improved.

The present invention can also be applied to the construction of curtain walls, towers, and the like.

[Advantages of the Invention] (1) Since a target with only a pinhole opened in the center is attached near the upper suspension part of another building material that is connected to the existing building material, on the upper part of the steel column There are advantages that there is no need to arrange a power source or power cable, there is no need to attach and detach it, and maintenance is unnecessary.

(2) Since the vertical point monitoring device is provided on the side of the existing steel column to concentrate the collimation information, there is an advantage that the information can be easily provided to the operator surely by the wired cable which avoids the radio wave which causes many obstacles.
