JP7742326B2 - Plumbing adjustment device and plumbing adjustment method for pillar members - Google Patents

Description

The present invention relates to a plumbing adjustment device and method for pillar members, and more specifically to a device and method for adjusting the inclination of pillar members installed successively above and below as designed when assembling the pillar members (erection).

When installing steel columns or other column components one above the other in succession, if their axes are tilted relative to the vertical, various problems can occur, such as the resulting structure tilting. Therefore, when assembling the column components, workers (marking technicians) would conduct surveying and adjust the tilt of the column components to ensure that the axial tilt was within the acceptable range. This plumbing adjustment work relies heavily on the skills of the workers (marking technicians), and because adjustment methods differ for each site (contractor), strict management was required to ensure that the accuracy of the plumbing adjustment was not affected.

A variety of technologies have been disclosed to reduce the burden of such plumbing adjustments. In particular, a technology has been disclosed that links a total station with an erection jig, thereby reducing the number of skilled workers required to erect steel columns to a single blacksmith and eliminating the need for marking work during plumbing measurement, thereby saving labor (see Patent Document 1).

The technology described in Patent Document 1 involves attaching a total station fixture to one end of a steel column, using a two-axis X- and Y-axis lifting platform to keep the suspended object always vertical. A total station is then attached to the total station fixture, and the steel column is lifted using a lifting device and installed in a designated position on the building. A measuring device is then used to adjust the plumbing of the steel column so that it fits within the standard. Next, the steel column with the total station attached is used as the column in the initial standard position, and the positions of other steel columns brought in subsequently are measured using the total station, and the plumbing adjustments of those other steel columns are then repeated in sequence.

JP 2016-121438 A

The technology described in the aforementioned Patent Document 1 presupposes the use of an erection jig for plumbing adjustments, and involves installing erection pieces at the joints (four locations on the four faces of each column) between a lower steel column installed below and an upper steel column installed continuously above this steel column. Then, an erection jig equipped with Z-axis adjustment bolts (tilt adjustment bolts), anti-tip bolts, misalignment adjustment bolts, fine adjustment cams (vertical position adjustment cams), and adjustment wedges is attached to a pair of erection pieces facing each other vertically.

A drive unit that rotates the Z-axis adjustment bolt (tilt adjustment bolt) is also attached to the erection jig. This drive unit is equipped with a motor , a reducer, a rotating shaft, and a universal shaft that fits onto the head of the adjustment bolt. By rotating the Z-axis adjustment bolt (tilt adjustment bolt) while controlling the drive unit, the position of the steel column is kept within the standard range for erection.

Incidentally, with an erection jig configured as described above, when the Z-axis adjustment bolt (tilt adjustment bolt) is rotated so that it moves downward, the tip of the adjustment bolt (tilt adjustment bolt) presses against the fine adjustment cam (vertical position adjustment cam), which operates on the principle of leverage and pushes the erection piece upward, allowing the steel column located above to move upward. On the other hand, when the Z-axis adjustment bolt (tilt adjustment bolt) is rotated so that it moves upward, the fine adjustment cam (vertical position adjustment cam) against which the tip of the adjustment bolt (tilt adjustment bolt) is pressing operates on the principle of leverage and pushes the erection piece downward, allowing the steel column located above to move downward.

At this time, the tip of the adjustment bolt (tilt adjustment bolt) presses against the fine adjustment cam (vertical position adjustment cam), causing the tilt of the adjustment bolt (tilt adjustment bolt) to fluctuate as the fine adjustment cam (vertical position adjustment cam) moves.

However, in the erection jig described in Patent Document 1, the Z-axis adjustment bolt (tilt adjustment bolt) and the drive unit for rotating it are fixedly attached to the erection jig. Therefore, even if the adjustment bolt (tilt adjustment bolt) tilts, the rotation shaft of the drive unit remains roughly vertical, resulting in different axial tilts between the adjustment bolt (tilt adjustment bolt) and the rotation shaft of the drive unit.

In this erection jig, the rotating shaft of the drive unit is connected to the adjustment bolt (tilt adjustment bolt) via a universal shaft. Patent Document 1 does not provide any detailed explanation of the universal shaft, so it is unclear what kind of structure the universal shaft is.

Even if the universal shaft has a universal joint in the middle of the shaft, or is a flexible shaft with a shaft made of a flexible material, if the adjustment bolt (tilt adjustment bolt) tilts, the rotating shaft of the drive unit will not be able to follow the tilt of the adjustment bolt, and the connection between the rotating shaft of the drive unit and the adjustment bolt (tilt adjustment bolt) may come loose. Even if the connection between the rotating shaft of the drive unit and the adjustment bolt (tilt adjustment bolt) does not come loose, an oblique force is applied to the connection between the rotating shaft of the drive unit and the adjustment bolt (tilt adjustment bolt), which could cause wear or damage to the connection.

Furthermore, universal shafts with a universal joint in the middle of the shaft have a complex structure, which not only increases the size of the device but also poses other disadvantages, such as the need for frequent maintenance. Furthermore, flexible shafts are unable to withstand large rotational torque and are at risk of breaking.

In this state, the integrity of the erection jig cannot be maintained, which in turn affects the accuracy of the plumbing adjustment. Therefore, the object of the present invention is to provide a plumbing adjustment device and adjustment method for pillar members that can adjust the vertical and horizontal positions of pillar members installed one above the other according to design without compromising the integrity of the erection jig.

The plumbing adjustment device and method for pillar members according to the present invention have the following features in order to achieve the above-mentioned objectives. Specifically, the plumbing adjustment device and method for pillar members according to the present invention relate to a device and method for adjusting the tilt of the upper pillar member (upper joint pillar) when connecting a pair of pillar members vertically and continuously.

The plumbing adjustment device for pillar members according to the present invention comprises an erection jig attached to multiple locations on the outer periphery of the pillar member, an error measurement means for measuring the error between the reference installation position of the pillar member (upper section pillar) located above and the actual installation position, and an inclination adjustment control means for controlling the operation of the erection jig so that the error measured by the error measurement means is within the allowable range.

The erection jig is equipped with erection pieces attached to multiple locations on the outer surface of each of a pair of vertically arranged column members to temporarily secure the pair, a connection means (erection jig main body) for connecting the opposing erection pieces of the pair of vertically arranged column members, and a vertical position adjustment means provided in the vertical middle of the connection means (erection jig main body) for adjusting the vertical position of the upper column member (upper joint column).

The vertical position adjustment means includes a vertical position adjustment cam that moves the column member (upper section column) located above up and down in the vertical direction, a tilt adjustment bolt that operates the vertical position adjustment cam and has a connecting hole on its top surface, and a tilt adjustment bolt operating means that operates the tilt adjustment bolt.

The tilt adjustment bolt operating means includes a rotating shaft that engages with a connecting engagement hole provided on the top surface of the tilt adjustment bolt, a rotation drive means that rotates the rotating shaft, and a power supply means that supplies power to the rotation drive means.

The tilt adjustment control means controls the tilt adjustment bolt operating means so that the error measured by the error measuring means falls within a tolerance range. The tilt adjustment bolt operating means tilts in accordance with the tilt of the tilt adjustment bolt .

The plumbing adjustment device for column members configured as described above is equipped with a pair of anti-rotation means that clamp the support steel plates protruding from the erection jig on both the left and right sides. These anti-rotation means are used to prevent the inclination adjustment bolt operating means from rotating in response to the rotation of the inclination adjustment bolt (rotating shaft). Furthermore, the connecting engagement hole and rotating shaft are provided with connecting and fixing means that connect and fix the rotating shaft to the connecting engagement hole.

The pillar member plumbing adjustment method of the present invention uses a pillar member plumbing adjustment device configured as described above to adjust the tilt of the upper pillar member (upper section pillar) when connecting a pair of pillar members vertically in succession. It includes an erection jig attachment process in which erection jigs are attached to multiple locations on the outer periphery of the pillar member; an error measurement process in which the error between the installation reference position and the actual installation position of the upper pillar member (upper section pillar); and an inclination adjustment process in which the erection jig is used to adjust the error between the installation reference position and the actual inclination position to within a tolerance range.

Then, in the tilt adjustment process, the operation of the erection jig is controlled so that the error measured by the error measurement means is within the allowable range, and the tilt adjustment bolt operating means is tilted to follow the tilt of the tilt adjustment bolt. Controlling the operation of the erection jig means controlling the tilt adjustment bolt operating means with the tilt adjustment control means.

In addition, in the plumbing adjustment method for column members that includes the above-mentioned steps, in the erection jig installation step, the tilt adjustment bolt operating means of the erection jig and the tilt adjustment bolt are integrally connected by using a connecting and fixing means to connect and fix the rotating shaft portion to the connecting engagement hole. In addition, in the tilt adjustment step, a rotation prevention means is used to prevent the tilt adjustment bolt operating means from rotating in conjunction with the rotation of the tilt adjustment bolt.

In the pillar member plumbing adjustment device and adjustment method of the present invention, the tilt of the pillar member (upper section pillar) is adjusted using an inclination adjustment bolt operating means to adjust the plumbing of the pillar member (upper section pillar). That is, the inclination of the pillar member (upper section pillar) is adjusted by rotating the inclination adjustment bolt using a rotary drive means. In this case, the inclination adjustment bolt operating means equipped with a rotary drive means tilts in accordance with the inclination of the inclination adjustment bolt used to adjust the inclination, thereby ensuring that the drive force from the rotary drive means is transmitted reliably to the inclination adjustment bolt.

Therefore, the pillar member plumbing adjustment device and adjustment method of the present invention make it possible to adjust the inclination of pillar members (upper section pillars) installed one above the other in succession as designed, without adversely affecting the operation of the jig (erection jig) used to perform the plumbing adjustment.

<Outline of the plumbing adjustment device>
The plumbing adjustment device according to an embodiment of the present invention is a device for adjusting the tilt of the upper section column 11 when connecting a pair of column members 10 (hereinafter, the column member 10 arranged on the upper side is referred to as the upper section column 11, and the column member 10 arranged on the lower side is referred to as the lower section column 12) in succession vertically, and is a device used, for example, when assembling steel columns.

As shown in Figure 1, this plumbing adjustment device mainly comprises an erection jig 100, an error measurement means 200, and an inclination adjustment control means 300. The erection jig 100 is a jig attached to multiple locations on the outer surface of the column member 10 to perform plumbing adjustments; for example, a Technos Corporation-made erection ace is used. The error measurement means 200 is a means for measuring the error between the installation reference position of the upper section column 11 and the actual installation position, and although not shown, is configured using, for example, a total station and its associated equipment.

As shown in FIG. 1, the erection jig 100 comprises an erection piece 20, a connection means (erection jig main body 30), and a vertical position adjustment means 40. The vertical position adjustment means 40 comprises a vertical position adjustment cam 41, an inclination adjustment bolt 42 having a connection hole 42a on its upper surface, and an inclination adjustment bolt operating means 43. The inclination adjustment bolt operating means 43 comprises a rotation shaft portion 43a, a rotation drive means 43b, and a power supply means 43c. The connection means (erection jig main body 30) is provided with a rotation prevention means 50. The connection hole 42a and the rotation shaft portion 43a are provided with a connection fixing means 60 that connects and fixes the rotation shaft portion 43a to the connection hole 42a.

<Erection jig>
The erection jig 100 is a jig used for erecting column members 10 such as column columns, round columns, and H-shaped steel columns, and temporarily fixes the column members 10 (upper section columns 11 and lower section columns 12) connected above and below to prevent them from falling over, and can also perform misalignment adjustments, tilt adjustments, level adjustments, etc. As shown in Figures 2 and 3 , this erection jig 100 includes erection pieces 20 attached to the lower part of the upper section column 11 and the upper part of the lower section column 12 so as to face each other, an erection jig main body 30 that functions as connection means by being attached so as to span the pair of erection pieces 20 facing each other above and below, and vertical position adjustment means 40 (vertical position adjustment cam 41, inclination adjustment bolt 42, inclination adjustment bolt operating means 43) that is provided in the vertical middle of the erection jig main body 30 (connection means) and adjusts the vertical position of the upper section column 11.

As shown schematically in Fig. 4, this erection jig 100 includes a control unit 70, a power supply means 43c , a power unit 80, and a rotation prevention means 50. The power unit 80 is a unit made up of a rotation shaft portion 43a and a rotation drive means 43b that constitute the inclination adjustment bolt operation means 43. The control unit 70, the power unit 80, the power supply means 43c (battery), and the rotation prevention means 50 will be described in detail later.

<Erection jig body>
2 and 3, the erection jig body 30 has an upper vertical groove 31 into which the erection piece 20 attached to the upper node column 11 is inserted, and a lower vertical groove 32 into which the erection piece 20 attached to the lower node column 12 is inserted. A space is provided between the erection piece 20 attached to the upper node column 11 and the erection piece 20 attached to the lower node column 12 for attaching a vertical position adjustment cam 41. In addition, a support steel plate 33 is provided that protrudes outward from the column member 10 so as to come into contact with the erection piece 20 attached to the upper node column 11.

A tilt adjustment bolt 42 is also attached so as to penetrate the support steel plate 33, with the tip of the tilt adjustment bolt 42 pressing against one end of the vertical position adjustment cam 41. An arrow pile 34 is inserted between the lower end surface of the vertical position adjustment cam 41 and the erection piece 20 attached to the lower section pillar 12. The lower end surface of the vertical position adjustment cam 41 abuts against the arrow pile 34, and the other end of the vertical position adjustment cam 41 presses against the lower end of the erection piece 20 attached to the upper section pillar 11. In other words, one end of the vertical position adjustment cam 41 serves as the force point, the lower end surface serves as the fulcrum, and the other end serves as the point of action, and the tilt adjustment bolt 42 adjusts the vertical position of the erection piece 20 attached to the upper section pillar 11.

Furthermore, as shown in Figures 2 and 3, the erection jig main body 30 is equipped with fixing bolts 35 for fixing the erection jig main body 30 to the erection piece 20 inserted into the upper vertical groove 31 by pressing them from the side, misalignment adjustment bolts 36 for adjusting the misalignment between the upper node column 11 and the lower node column 12 by pressing them from both the left and right sides against the erection piece 20 inserted into the lower vertical groove 32, and tip-over prevention bolts 37 for preventing the upper node column 11 from tipping over by pressing them from below against the erection piece 20 inserted into the lower vertical groove 32. In this embodiment, these components are operated by the worker.

<Erection Piece>
As shown in Figures 2 and 3, the erection piece 20 is a member attached to the lower part of the upper node column 11 and the upper part of the lower node column 12, and in a column member 10 having multiple side surfaces, multiple pairs of opposing side surfaces are attached as a set. For example, in the case of a column member 10 with a square cross section, an erection piece 20 is attached to each side surface (four side surfaces). This erection piece 20 is a plate-shaped member and is attached in the vertical direction on the side surface of each column member 10 so as to protrude outward from each column member 10.

In addition, a space is provided between the lower end of the erection piece 20 attached to the upper section pillar 11 and the upper end of the erection piece 20 attached to the lower section pillar 12 to allow for the placement of components such as the vertical position adjustment cam 41. The attachment locations and number of erection pieces 20 (the attachment locations and number of erection jigs 100) are set appropriately depending on the shape, size, weight, etc. of the pillar member 10.

<Vertical position adjustment means>
As described above, the vertical position adjustment means 40 is provided in the vertical middle of the erection jig body 30 (connection means), and adjusts the vertical position of the upper section column 11 by adjusting the vertical position of the erection piece 20 attached to the upper section column 11. The vertical position adjustment means 40 mainly comprises a vertical position adjustment cam 41, an inclination adjustment bolt 42, and an inclination adjustment bolt operating means 43.

In this embodiment, the tilt adjustment bolt operating means 43 (rotating shaft 43a, rotation drive means 43b), which is the power unit 80, the power supply means 43c (battery), and the control unit 70 are housed in the storage case 44. These units and devices are also integrated with the rotation prevention means 50. That is, as shown in Figure 4, these components are housed in the storage case 44 as the control unit 70, power unit 80, and power supply means 43c (battery), and the storage case 44 and the rotation prevention means 50 are integrated.

<Up/down position adjustment cam>
The vertical position adjustment cam 41 has a plate-shaped portion 41a that comes into contact with the tip of the tilt adjustment bolt 42 to become the force point, and a cylindrical portion 41b that presses against the lower end of the erection piece 20 attached to the upper joint column 11 to become the point of action, and presses against the sheet pile 34 inserted into the upper end of the erection piece 20 attached to the lower joint column 12 to become the fulcrum (the upper surface is the point of action, and the lower surface is the fulcrum). In other words, the vertical position adjustment cam 41 is a lever with a cylindrical bulge at the tip side and a plate-shaped base end side.

<Tilt adjustment bolt>
The inclination adjustment bolt 42 is screwed so as to vertically penetrate the support steel plate 33 that protrudes outward from the erection jig main body 30. When the tip of the inclination adjustment bolt 42 is rotated so that it protrudes downward, the tip of the inclination adjustment bolt 42 presses against the upper surface of the plate-shaped portion 41 a (one end) of the vertical position adjustment cam 41, pushing the plate-shaped portion 41 a (one end) downward. On the other hand, when the inclination adjustment bolt 42 is rotated so that it protrudes upward, the weight of the upper section pillar 11 pushes back the plate-shaped portion 41 a (one end) of the vertical position adjustment cam 41. In other words, the upper section pillar 11 can be moved up and down in response to the rotation of the inclination adjustment bolt 42.

Furthermore, multiple sets of erection jigs 100 with inclination adjustment bolts 42 are attached to a column member 10 with multiple side faces, with each set consisting of a pair of opposing side faces. Therefore, by operating the inclination adjustment bolts 42, the vertical position adjustment cams 41 operate, allowing the inclination of the upper section column 11 to be adjusted.

<Connection hole>
A connecting hole 42a that engages with the rotation shaft portion 43a of the tilt adjustment bolt operating means 43 is provided on the top surface of the tilt adjustment bolt 42. This connecting hole 42a is provided at a position that becomes the center of rotation on the top surface of the head of the tilt adjustment bolt 42. This connecting hole 42a and the rotation shaft portion 43a are provided with a connecting and fixing means 60 that connects and fixes the rotation shaft portion 43a to the connecting and fixing hole 42a. The connecting and fixing means 60 will be described in detail later.

<Tilt adjustment bolt operating means>
The tilt adjustment bolt operating means 43 is a means for rotating the tilt adjustment bolt 42, and is composed of a rotary shaft portion 43a, a rotary drive means 43b, and a power supply means 43c.

<Rotating shaft>
The rotating shaft 43a is a member for transmitting the rotational force of the rotation drive means 43b (electric motor), and is adapted to engage with a connecting hole 42a provided on the upper surface of the tilt adjustment bolt 42. In this embodiment, the connecting hole 42a is a recess with a circular cross section, and therefore the rotating shaft 43a is cylindrical and fits into the recess.

<Rotational driving means>
The rotation drive means 43b is a means for rotating the rotation shaft portion 43a and is constituted by, for example, an electric motor. By connecting and fixing the rotation shaft portion 43a of the rotation drive means 43b (electric motor) to the connecting hole 42a, the tilt adjustment bolt 42 can be rotated by driving the rotation drive means 43b (electric motor). This rotation drive means 43b (electric motor) is stored in the storage case 44 together with the power supply means 43c (battery).

<Power source>
The power supply means 43c is a means for supplying power to the rotation drive means 43b (electric motor) and is made up of, for example, a battery. There are no particular limitations on the type of battery, but it is preferable that the battery has sufficient drive voltage, current, and capacity to rotate the rotation shaft 43b and is highly durable. In this embodiment, the power supply means 43c is a battery, but power may also be supplied directly from a power line.

<Rotation prevention means>
The rotation prevention means 50 is a means for preventing the inclination adjustment bolt operating means 43 and associated devices from rotating in response to the rotation of the inclination adjustment bolt 42. The rotation prevention means 50 is composed of a pair of rotation prevention plates 51 arranged to sandwich the support steel plate 33 of the erection jig main body 30 from both sides. The pair of rotation prevention plates 51 are positioned outside the inclination adjustment bolt 42 with respect to the column member 10 and are each arranged to protrude downward from the erection jig main body 30. The distance between the pair of rotation prevention plates 51 is set to be slightly (e.g., approximately 2 mm) larger than the width of the support steel plate 33. As described above, the rotation prevention means 50 is integrated with the control unit 70, the inclination adjustment bolt operating means 43 (rotation shaft portion 43a, rotation drive means 43b) which is the power unit 80, and the power supply means 43c (battery).

When the storage case 44 is placed over the tilt adjustment bolt 42 from above the erection jig 100, the rotating shaft 43a engages with the connecting hole 42a of the tilt adjustment bolt 42, and the pair of anti-rotation plates 51 clamp the support steel plate 33. In this state, when the connecting and fixing means 60 is used to connect and fix the rotating shaft 43a to the connecting hole 42a, the tilt adjustment bolt 42 and storage case 44 are integrally connected. Furthermore, the anti-rotation means 50 prevents the storage case 44 from rotating in conjunction with the rotation of the rotating shaft 43a. With this configuration, the erection jig main body 30, including the storage case 44, tilts in accordance with the tilt of the tilt adjustment bolt 42.

<Tilt Adjustment Control Means>
The tilt adjustment control means 300 is a means for controlling the operation of the erection jig 100 (specifically, the tilt adjustment bolt operation means 43) so that the error measured by the error measurement means 200 is within the allowable range, and as shown in Figure 1, it is composed of a control unit 70 with computer functions and a control PC that sends and receives data to and from this control unit 70 using wireless LAN.

The control unit 70 is housed in a storage case 44 together with the tilt adjustment bolt operating means 43 (rotating shaft 43a, rotary drive means 43b), which is the power unit 80, and a battery, which is the power supply means 43c. The storage case 44 also contains wireless LAN means (not shown), and the control unit 70 uses the wireless LAN to send and receive data with a control PC. In other words, the control unit 70 controls the tilt adjustment bolt operating means 43 by operating based on signals received from the control PC.

<Control PC>
The control PC can be configured, for example, as a laptop computer, and transmits and receives data to and from the total station. A program is installed in the control PC for controlling the tilt adjustment bolt operating means 43 so that the tilt error of the upper section column 11 measured by the total station, which is the error measurement means 200, falls within the allowable range. The control PC then transmits a control signal to the control unit 70 via wireless LAN based on the error data received from the total station, and controls the tilt adjustment bolt operating means 43 via the control unit 70, thereby keeping the tilt error of the upper section column 11 within the allowable range.

<Coupling and fixing means>
The connecting and fixing means 60 will be described with reference to Figures 5 and 6. Figure 5(a) is a side view of the connecting and fixing means 60, Figure 5(b) is a top view of the tilt adjustment bolt 42, and Figure 6 is a side view of the connecting and fixing means 60 in an exploded state.

The connecting and fixing means 60 is a means for connecting and fixing the rotating shaft portion 43a to the connecting and fixing hole 42a. As shown in Figures 5 and 6, the connecting and fixing means 60 in this embodiment consists of keyways 61a, 61b provided on the inner surface of the connecting and fixing hole 42a and the outer peripheral surface of the rotating shaft portion 43a, respectively, facing each other; a parallel key 62 that fits into the facing keyways 61a, 61b; multiple fixing screw insertion holes 63 that extend from the outer peripheral surface of the head of the tilt adjustment bolt 42 toward the connecting and fixing hole 42a; and fixing screws 64 that are screwed into the fixing screw insertion holes 63 so that their tips abut against the parallel keys 62 or the outer peripheral surface of the rotating shaft portion 43a.

Although not shown, the fixing screw 64 has a male thread on its outer surface and a wrench insertion hole in its head for inserting a wrench (e.g., a hex wrench). In this embodiment, three adjacent fixing screw insertion holes 63 are provided, evenly spaced 120° apart.

Then, the key groove 61a on the inner surface of the coupling hole 42a is aligned with the key groove 61b on the outer surface of the rotating shaft portion 43a, and the rotating shaft portion 43a is inserted into the coupling hole 42a so that the parallel key 62 fits into both key grooves 61a and 61b. In this state, the fixing screw 64 is inserted into the fixing screw insertion hole 63 and screwed in so that the tip of the fixing screw 64 abuts against the parallel key 62 or the outer surface of the rotating shaft portion 43a, thereby coupling and fixing the rotating shaft portion 43a to the coupling hole 42a.

<Error measurement means>
The error measurement means 200 of this embodiment is a means for measuring the error between the reference installation position of the upper section column 11 and the actual installation position, and its main component is, for example, a total station (not shown). The total station is a device that combines an electronic distance meter, which measures distance by emitting a beam of light toward a measurement target point and electronically analyzing the beam of light reflected from the measurement target point, with a digital theodolite, which measures angles. The total station can simultaneously measure angles (vertical angle and horizontal angle) and distance, and can also transmit measurement result data to a calculation device (control PC).

This embodiment will be described using a total station as the error measurement means 200. In this embodiment, the total station is connected to a control PC (notebook computer) so that data can be communicated. Therefore, the operation of the total station can be controlled by the control PC, and distance measurement result data can be imported into the control PC. The display screen of the control PC (the liquid crystal display screen of the notebook computer) displays various operation icons for controlling the operation of the total station, and the operation of the total station is controlled using these operation icons.

The distance measurement results data are also displayed on the display screen of the control PC (the LCD screen of a laptop computer). Since the total station has computer functions and a display device, control and data display can also be performed within the total station itself.

The total station is installed in an appropriate position, and targets (prisms) are installed at two reference points with known coordinates. The installation position (self-position) of the total station can be calculated by measuring the distance between the targets (prisms) installed at the two reference points. Only one target (prism) is required, and the target (prism) is moved and installed at the reference point each time the distance to each reference point is measured. In addition, a dedicated target sticker 90 is installed in an appropriate position on the upper section column 11.

To measure the tilt error of the upper section column 11, the target seal 90 of the upper section column 11 is sighted and positioned using a total station, and the deviation (error) from pre-stored reference position data is calculated. Based on the calculation results, the control PC controls the operation of the vertical position adjustment means 40 attached to the upper section column 11, thereby adjusting the tilt of the upper section column 11 so that the tilt error of the upper section column 11 falls within the reference value range. For example, if an erection jig 100 is attached to each side (four faces) of the upper section column 11, which is a square column, the tilt of the upper section column 11 is adjusted by adjusting the vertical position of the upper section column 11 in three mutually orthogonal axial directions (the vertical Z axis, and the horizontal X and Y axes).

In addition, 3D CAD model data, which is the design value, can be stored, and the 3D CAD model data can be displayed in AR. The image recognition function can then be used to detect the edges of the upper section pillar 11, and the error between the edge data detected by image recognition and the coordinate data selected in AR can be calculated to measure the tilt error of the upper section pillar 11.

<Outline of the Pitch Adjustment Method>
The plumbing adjustment method according to the present invention is a method for adjusting the tilt of the upper column member 10 (upper section column 11) when connecting a pair of column members 10 vertically in succession using the plumbing adjustment device described above, and as shown in FIG. 7, includes the following main steps: an erection jig installation step (S100), an error measurement step (S200), and an inclination adjustment step (S300).

<Erection jig installation process>
The erection jig attachment process (S100) is a process for attaching the erection jig 100 to multiple locations on the outer peripheral surface of the column member 10. In this erection jig attachment process (S100), the connecting and fixing means 60 is used to connect and fix the rotation shaft portion 43a to the connecting and fixing hole 42a, thereby integrally connecting the inclination adjustment bolt operating means 43 of the erection jig 100 and the inclination adjustment bolt 42.

<Error measurement process>
The error measurement step (S200) is a step for measuring the error between the installation reference position and the actual installation position of the upper section column 11. In this error measurement step (S200), a total station is used to perform surveying and error measurement. Note that the total station may only perform surveying, and the survey result data may be transmitted to a control PC, where the error may be calculated.

<Tilt adjustment process>
The tilt adjustment process (S300) is a process for adjusting the error between the installation reference position and the actual installation position using the erection jig 100 (tilt adjustment bolt operating means 43) under the control of the tilt adjustment control means 300 so that it falls within a tolerance range. In this tilt adjustment process (S300), the rotation shaft portion 43a and the rotation drive means 43b are connected and fixed by the connecting and fixing means 60, so that the tilt adjustment bolt operating means 43 can be tilted in accordance with the tilt of the tilt adjustment bolt 42. Furthermore, in the tilt adjustment process (S300), the rotation prevention means 50 is used to prevent the tilt adjustment bolt operating means 43 from rotating in accordance with the rotation of the tilt adjustment bolt 42.

<Control flow (main routine)>
The error measurement step (S200) and the inclination adjustment step (S300) will now be described in detail. As described above, the error measurement means 200 (total station) and the inclination adjustment control means 300 (control PC) are connected via a connection cable so as to be able to send and receive data, and the control PC and the plumbing adjustment device (vertical position adjustment means 40) are connected via a wireless LAN so as to be able to send and receive data.

The following explanation assumes that an erection jig 100 is attached to each side (four faces) of the column member 10 (upper section column 11 and lower section column 12) consisting of a square column, and describes three mutually perpendicular axial directions (the vertical direction is the Z axis, and the horizontal directions are the X axis and Y axis), with each plumbing adjustment device (vertical position adjustment means 40) being A, B, C, and D. As shown in Figure 12, A and C (X axis direction), and B and D (Y axis direction) are plumbing adjustment devices installed on opposing side faces.

As shown in Figure 8, when the "Start Plumbing" button is pressed on the control PC's operation screen to instruct the error measurement means 200 (total station) and plumbing adjustment device (vertical position adjustment means 40) to start plumbing (S1), a surveying start signal is sent to the total station (S2), and the total station sights in on the target (target seal 90 installed on the upper section pillar 11) and performs a survey (S3, S4), and compares the surveyed position data with the reference position data, which is the design value, to calculate an error value (S5).

When the control PC receives the error value (S6), it performs the Z-axis adjustment process (S7), the X-axis adjustment process (S8), and the Y-axis adjustment process (S9), and then performs the Z-axis adjustment process again (S10) to determine whether the errors on all three axes are within the allowable range (S11). If the errors on all three axes are within the allowable range, the plumbing adjustment process ends.

On the other hand, if the error on any of the three axes exceeds the tolerance range, the process returns to the initial Z-axis adjustment step (S7), and each adjustment step (S7-S10) is repeated until the error on all three axes is within the tolerance range.

<Subroutine (Z-axis adjustment)>
Next, the Z-axis adjustment subroutine will be described. As shown in Figure 9, in the Z-axis adjustment subroutine, the plumbing adjustment device is operated, and once its operation has been confirmed (S7a), a survey instruction signal is sent to the total station (S7b), as described in the main routine. The total station then sights the target (the target seal 90 attached to the upper section pillar 11) and measures it (S7c, S7d), and compares the measured position data with the reference position data, which is the design value, to calculate an error value (S7e).

When the control PC receives the error value (S7f), it determines whether the Z-axis error is within the allowable range (S7g), and if the Z-axis error is within the allowable range, it ends the Z-axis adjustment subroutine.

On the other hand, if the Z-axis error exceeds the tolerance, it is determined whether the error is positive or negative (S7h). If the error is positive, an UP command (raise command) is sent to all of the plumbing adjustment devices (A, B, C, D) ( S7i ). If the error is negative, a DOWN command (lower command) is sent to all of the plumbing adjustment devices (A, B, C, D) (S7j). The plumbing adjustment device performs a plumbing adjustment operation (S7k) to attempt to eliminate the Z-axis error. The Z-axis adjustment process is then repeated until the Z-axis error is within the tolerance, and once the Z-axis error is within the tolerance, the Z-axis adjustment subroutine is terminated.

<Subroutine (X-axis adjustment)>
Next, the X-axis adjustment subroutine will be described. As shown in Figure 10, in the X-axis adjustment subroutine, the plumbing adjustment device is operated, and once its operation has been confirmed (S8a), a survey instruction signal is sent to the total station (S8b), as described in the main routine. The total station then sights the target (the target seal 90 attached to the upper section pillar 11) and measures it (S8c, S8d), and compares the measured position data with the reference position data, which is the design value, to calculate an error value (S8e).

When the control PC receives the error value (S8f), it determines whether the X-axis error is within the allowable range (S8g), and if the X-axis error is within the allowable range, it ends the X-axis adjustment subroutine.

On the other hand, if the X-axis error exceeds the tolerance, it is determined whether the error is positive or negative (S8h). If the error is positive, an UP command (raise command) is sent to the plumbing adjustment device A, and a DOWN command (lower command) is sent to the plumbing adjustment device C (S8i). If the error is negative, an UP command (raise command) is sent to the plumbing adjustment device C, and a DOWN command (lower command) is sent to the plumbing adjustment device A (S8j). The plumbing adjustment device performs plumbing adjustment (S8k) to attempt to eliminate the X-axis error. The X-axis adjustment process is then repeated until the X-axis error is within the tolerance. Once the X-axis error is within the tolerance, the X-axis adjustment subroutine is terminated.

<Subroutine (Y-axis adjustment)>
Next, the Y-axis adjustment subroutine will be described. As shown in Figure 11, in the Y-axis adjustment subroutine, the plumbing adjustment device is operated, and once its operation has been confirmed (S9a), a survey instruction signal is sent to the total station (S9b), as described in the main routine. The total station then sights the target (the target seal 90 attached to the upper section pillar 11) and measures it (S9c, S9d), and compares the measured position data with the reference position data, which is the design value, to calculate an error value (S9e).

When the control PC receives the error value (S9f), it determines whether the Y-axis error is within the allowable range (S9g), and if the Y-axis error is within the allowable range, it ends the Y-axis adjustment subroutine.

On the other hand, if the Y-axis error exceeds the allowable range, it is determined whether the error is positive or negative (S9h). If the error is positive, an UP command (raise command) signal is sent to the plumbing adjustment device B, and a DOWN command (lower command) signal is sent to the plumbing adjustment device D (S9i). If the error is negative, an UP command (raise command) signal is sent to the plumbing adjustment device D, and a DOWN command (lower command) signal is sent to the plumbing adjustment device B (S9j). The plumbing adjustment device performs plumbing adjustment operations (S9k) to attempt to eliminate the Y-axis error. The Y-axis adjustment process is then repeated until the Y-axis error is within the allowable range. Once the Y-axis error is within the allowable range, the Y-axis adjustment subroutine is terminated.

<Specific examples of control methods>
A specific example of the above-mentioned inclination adjustment step (S300) will be described using the schematic diagram shown in Fig. 12. In Fig. 12, (a) is a plan view showing the target posture of the column member 10, (b) is an elevation view showing the posture of the column member 10 before adjustment, and (c) is an elevation view showing the target posture of the column member 10 after adjustment. As shown in Fig. 12(a), the upper section column 11 has a rectangular cross section, and the plumbing adjustment devices attached to the side surfaces opposite each other in the X-axis direction are designated as A and C, and the plumbing adjustment devices attached to the side surfaces opposite each other in the Y-axis direction are designated as B and D, respectively.

In Figure 12(b), assume that the upper section column 11 is tilted to the right in the X-axis direction (the error Δx in the X-axis direction is 10 mm, the error Δy in the Y-axis direction is 0 mm, and the error Δz in the Z-axis direction is 1 mm, within the allowable range). In this case, the left side of the upper section column 11 is lowered by plumbing adjustment device A, and the right side of the upper section column 11 is raised by plumbing adjustment device C, thereby eliminating the tilt of the upper section column 11 in the X-axis direction, as shown in Figure 12(c). The same applies to adjusting the tilt in the Y-axis direction, but plumbing adjustment devices B and D are used for this adjustment. In addition, in the Z-axis direction, all of the plumbing adjustment devices (A, B, C, D) are raised or lowered to adjust the position of the upper section column 11.
