And at least.

The vertical device 37 as the positioning device is
The vertical device can be set by focusing on the reference black marked on the beam or the deck plate and setting the vertical device. At this time, as shown in FIGS. In the case where a dedicated jig 44 or a setting plate 45 having a mounting screw portion 44a at the center of the base or a column building work has proceeded to the upper floor, as shown in FIG. L-shaped angle piece 36b holding the
Is used as it is, and a metal or synthetic resin setting plate 45 attached with bolts and nuts is used.

The vertical device 37 is a vertical device which can also focus on a mark 36a of a target 36 which is about 10 m above a lower portion of a pillar 34 to be built. As an example, FPM
FG-L made by Holding GmbH (Germany)

In the control device 39, for example, when the setting adjustment jigs 32 are set at four places around the pillar 34 to be set, one setting adjustment jig 32 is set. Only and only the adjusting jig 32
Is operated such that the screw rod 8 and the locking member 3 are raised, in particular, the control.

The procedure of the method for erection of a pillar according to the present invention will be described using the column erection system 33 according to the present invention thus configured.

First, as shown in FIG.
The reference black ink is printed. Next, as shown in FIG. 11B, the lifting jig 1 for erection is temporarily attached to each of the erection pieces 7 welded at four places around the pillar 35.

For this, as shown in FIG. 12, a bolt 5 having a retaining function is used. That is, a through hole 5a having a step in the radial direction is drilled at the tip of the bolt 5,
A retaining pin 5b is loosely fitted in the through hole 5a so as to be able to protrude and retract from the surface of the bolt shaft. The hole of the erection piece 7 and the through hole 4 of the locking member 4 of the lifting jig 1 are formed.
a, 4a and the bolt 5 is inserted therethrough,
When the bolt 5 is rotated around its axis, as shown in FIG. 3, the retaining pin 5b falls naturally and projects to prevent it from falling off.

The retaining pin 5b has a retaining ring on its head side for preventing the falling off from being inserted into the through hole 5a so that it does not fall off. This eliminates the need to use nuts and wainspins to prevent the bolt 5 from coming off, and saves time and effort.

Further, as shown in FIG. 13, a retaining plate 5 which is rotatable about a radial axis and has a tapered end surface on the bolt head is provided at the tip of the bolt 5c.
By providing d, when inserting into the through hole, insert it in the state of (a) and when preventing it from falling out, rotate the bolt head by 180 ° as shown in (b) and rotate it by its own weight. Protruding the retaining plate 5d from the outer periphery of the bolt,
You may make it act as a retainer.

The locking member 4 is rotatable around the bolt 5 or the bolt 5c.
Of the erection piece 7 or a part of the connecting plate 42 described later,
It is preferable that the lifting jig 1 is held in an inclined state because it is easy to handle in operation.

Next, as shown in FIGS. 14A to 14D, pillars 34 to be built brought into the building site by trucks or the like.
The target 36 is attached to a predetermined position on the head of the device, and is suspended by a crane. Then, the column 34 is placed on the column 35 of the lower section.

A pair of upper and lower erection pieces 6 and 7 are respectively provided at four places around the pillars 34 and 35 for building.
Then, a metal plate-like connecting plate 42 is attached so as to be sandwiched from both sides, and temporarily fixed with bolts and nuts.

Then, the lifting jig 1 for each building, which has been waiting in an inclined state, is raised, and the locking member 3 is fixed to the erection piece 6 of the column 34 with a bolt 5 to prevent the bolt 5 from being removed. The pins 5b are protruded downward and locked. Thereafter, the sling of the crane is removed from the column 34, and the crane is used for the next column.

Next, as shown in FIGS. 15A and 15B, the driving jig 2 is attached to each lifting jig 1 for mounting, and the mounting member 14 of the locking member 4 in the lifting jig 1 is attached. , 15 are engaged with the attachment means 29, 30 of the driving jig 2 and attached. Thereby, the spur gear 13 of the lifting jig 1 and the spur gear 24 of the driving jig 2 mesh with each other, so that rotation can be transmitted.

The electric motor 26 of each of the driving jigs 2
And the electromagnetic brake 27 is electrically connected to the control device 39 by a cable. Further, the vertical device 37 is set via the setting jig 44 in accordance with the reference black marked on the beam 41. When there is reference black on the deck plate, it is convenient to use the setting plate 45.

A CCD camera 38 a is attached to the vertical device 37, and the camera cable is connected to the image processing device 38. The image processing device 38 and the control device 39 are electrically connected in a device frame provided with them. Also,
A monitor 38b (see FIG. 5) is also connected to the image processing device 38.

After the pillar installation system 33 is constructed around the pillar 34 to be installed in this way, FIG.
As shown in (5), the control device 39, the image processing device 38, and the CCD camera 38a are operated to perform a later-described construction adjustment.

After the completion of the installation adjustment, FIG.
As shown in the figure, the bolts and nuts in the connection plate 42 are fully tightened, and
Hold 4. Then, the pillar installation system 33 is removed. After welding and connecting the column 34 and the column 35,
The erection pieces 6 and 7 are cut from the pillar and removed together with the connection plate 42.

The method for adjusting the building will be described. As shown in FIG. 5 and FIGS.
The location adjustment jigs 32 (hereinafter, also simply referred to as jacks) are A, B, C, and D, and the four quadrants defined by the X-Y orthogonal coordinates on the monitor screen 38c are A and B correspondingly. , C, D.

An example in which the mark 36a is first in the D quadrant on the monitor screen 38c will be described according to an adjustment flow as shown in FIGS.

When the installation adjustment is started, as shown in FIG. 18, the control device 39 recognizes that it is in the D quadrant based on the position data from the image processing device 38, and operates the jack at the D position of the column 34. Let it.

Then, since the mark 36a is lifted at the position D of the pillar 34, the mark 36a always moves within a certain range (a direction approaching the allowable range 40) toward one of the quadrants A and C. Then, it is determined whether the mark 36a has reached either the X axis or the Y axis.

For example, when the mark 36a moves in the direction of the arrow shown in FIG. 17 (b) and reaches the Y axis, the process proceeds to the adjustment flow shown in FIG. 19, and the D jack is once operated. Stop.

Then, the absolute value of the Y coordinate value of the position data is limited to the limit Y3 (here, Y3 means that the position is adjusted in three steps, specifically, Y3 = 5 m).
m, Y2 = 3 mm, Y1 = 1 mm, or Y3 = 3 m
m, Y2 = 2 mm, Y1 = 1 mm, etc. can be set arbitrarily. This limit value is also represented by an absolute value. The X coordinate value is handled in the same way.)
If it is "large", the jack of D is further operated, and the jack of D is operated until the limit X3 or the limit Y3 is reached.

If it is "small", the jack D is operated to reach the next limit X2 or Y2.

Next, when the mark 36a reaches, for example, the limit X3, the D jack is stopped. Then, the flow of the flow returns to the adjustment start position in FIG.
When the control device 39 recognizes that the position data of the mark 36a is in the quadrant A, the jack at the position A is operated by the control device 39 this time.

The mark 36a moves toward any one of the quadrants B and D, and operates the jack A until the X-axis or the Y-axis is reached. Determine if it has arrived.

Next, when the mark 36a reaches the Y-axis, for example, as shown in FIG. 19, "D jack" is replaced with "A jack" in this figure, and the A jack is once stopped. Let it. The controller 39 determines whether the X or Y coordinate value of the mark 36a is "larger" than the limits X2 and Y2.

If the value is larger than the limit X2 or Y2, the jack A is operated to limit the limit X2.
2 or Y2. If it is "small", the jack of A is operated as it is to reach the next limit X1 or Y1. When the mark 36a reaches each limit, the A jack is stopped, and the process returns again to the start of the adjustment. By repeating such a procedure, the mark 36a is allowed to reach the allowable range 40, and the installation adjustment is completed.

Up to now, the case where the mark 36a has reached the Y axis has been described with reference to FIG.
If the X-axis is reached, the adjustment flow is as shown in FIG. FIG. 20 shows a flow in which Y in FIG. 19 is replaced with X.

When the adjustment is started and the mark 36a is located in a quadrant other than the D quadrant, the "D jack" shown in FIGS. 19 and 20 is replaced by the "C jack" shown in FIGS. The adjustment flow is read as "B jack" for a quadrant and "A jack" for an A quadrant.

In this manner, the jacks, which are the four adjusting jigs 32, are operated for each position under the control of the control device 39, and the mark 36a is moved from a certain quadrant in the XY orthogonal coordinates. The jack is moved to another quadrant, and the limit (X, Y) value is reduced every time the user moves to another quadrant. And converge toward.

Although there are various methods for narrowing down the marks 36a depending on the program, in the present invention,
In order to obtain a reliable and stable operation, the lifting jig 1 for erection at one place is always operated.
Further, since the convergence (convergence) method is performed in three stages, the method is the most suitable method of the present embodiment. Of course, two lifting jigs 1 may be operated at the same time so as to approach the allowable range 40 at the shortest distance.

Another embodiment of the building system according to the present invention relates to an improvement of a vertical device 37 which is a positioning device which is positioned to the reference black.

As shown in FIG. 24, the positioning device 4
8, at least one or more image pickup device (for example, a CCD camera) 50 is provided inside a cylindrical container 49, and this positioning device is fixed to a setting jig 44 or a tripod stand 53. The image processing device 38 directly captures the reference black and the mark 36a of the target 36, and uses the captured image as image data in the image processing device 38, for example, a wired transmission method using a cable 51 or a transmitter in the image pickup device 50.
8 is provided with a receiver so as to be transmitted by a wireless transmission method.

In another embodiment, as shown in FIG. 25, two CCD cameras as an image pickup device 50 are arranged in series inside the cylindrical container 49, and both CCD cameras 5
The 0,50 optical axes are aligned. In order to make the optical axes coincide with each other, an adjusting means 50a for finely adjusting the left / right position and the inclination of each CCD camera 50 is provided. The adjustment of the optical axis is adjusted in advance at the manufacturing plant of the positioning device or the like so as to match.

An appropriate interchangeable lens 55 is attached to the CCD camera 50 so that the focus can be focused on the reference black or the mark 36a of the target 36 by, for example, an auto iris (auto focus). The image processing device 38 includes a remote control device for the interchangeable lens 55, and the exposure of the interchangeable lens 55 is adjusted by the image processing device 38. Also,
It is preferable that the cylindrical container 49 is provided with a handle for transportation. Further, depending on the situation at the site, the CCD camera 5
The transmitter 51b can be set to 0.

The target 36 captured by the CCD camera
After the image data of the mark 36a is transmitted to the image processing device 38, it is displayed on the monitor 38. This monitor is changed to a liquid crystal monitor 38d provided near the positioning device 48 as shown in FIG. As shown in FIG. 27, a goggle type monitor (for example, a personal LCD monitor; manufactured by SONY) provided in front of the worker's eyes
52.

According to the goggle-type monitor 52, the ordinary monitor 38b may be difficult to see due to sunlight, its reflection, etc. because the work is performed outside, but such inconvenience is solved. It is. The exchange of image data between the monitor 52 and the image processing device 38 can be transmitted by wire or wirelessly. In this way, the action of the worker becomes free.

Further, as shown in FIG. 28, the operation of the control device 39 electrically connected to the image processing device 38 is controlled by the remote control device 54 at hand of the operator. It is preferable that the operator can start the installation work from a place remote from the control device 39.

According to such another embodiment, the positioning device 48 can be replaced by the C vertical without using the expensive vertical device 37.
The cost can be reduced because the CD camera 50 can make up for the delay. Further, by transmitting the image data between the image processing device 38 and the positioning device in a wireless manner, for example, the positioning device 48 is set in accordance with the reference black on the first floor of the building, and the upper floor is kept as it is. Without moving the positioning device 48, the other image processing devices 38 and the control device 39 in the building system can be moved to the upper floor as the building progresses.

As shown in FIG. 29, the column 34 at the node 0
In order to set the driving jig 2 for installation, the mounting jig can be adjusted by preparing a mounting device so that the driving jig 2 can be set on the upper side in the vertical direction. The mark 36a of the target 36 attached to the pillar 34 to be built on the third floor or the fourth floor, for example, is visually recognized from below from the floor of the first floor on which the positioning device 48 is set. In this case, a space or an opening necessary for the operation is provided.

Further, by remotely controlling the control device 39 by radio, the degree of freedom of the worker's action is increased, and the installation can be adjusted by one worker until the pillars are fully tightened.

Then, in the control device 39, the image data from the CCD camera 50 in the positioning device 48 can be stored in a magnetic recording device such as an FD floppy disk, a hard disk, or a magnetic tape. later,
By reproducing the image data with a reproducing device such as a personal computer, it is possible to confirm the state of building the pillars.

In addition, a vertical device 3 as a positioning device
In the setting plate for moving the positioning device 48 shown in FIG. 7 or FIG. 24 to the pillar 34 on which the pillar is to be installed on the upper floor, when the pillar 34 is narrowed down toward the upper floor, It is preferable that the mounting hole is a long hole in which the mounting hole is lengthened by the narrowed column so that one set plate can be used.

As described above, according to the method of erection of the pillar of the present invention, the pillar 34 can be erected reliably and quickly. In this embodiment, about one to two minutes from the start of the adjustment of the erection. Is completed. By the way, in the method of adjusting by a skilled person according to the conventional method, an adjustment time of about 5 minutes is required.
