As a result, the center of gravity is located on the rotation axis 35 on the PQ line.
In the laser oscillator 31 in which the weight is distributed so as to be positioned below A and B, the upper surface portion 31A is always horizontally upward P
It is balancedly supported by the gantry 32 so as to be zero. As a result, the laser light L1 is always stably emitted vertically upward from the laser light emitting port 31B. The laser oscillator 31 and the pedestal 32 are housed in a main body case 39 shown in FIG. On the side surface of the main body case 39, three support members 39A that support the main body case 39 are installed so as to project.

As shown in FIG. 10, the laser device 20 is housed in the insertion jig 40 and is suspended by the suspension wire 21 on the bottom portion 8A of the guide pipe 8 or the bottom portion 9A of the guide pipe 9. The insertion jig 40 is made of stainless steel, and is fixed on a disk-shaped base 41 with the laser emission port 31B of the laser device 20 facing upward. On the pedestal 41, the peripheral portion 41A is sized so as to come into contact with the inner wall of the guide pipe 8 or 9 with a slight gap, whereby the center position of the pedestal 41 is the center line G2 of the guide pipe 8 or the center line of the guide pipe 9. Located on G3. Accordingly, the laser device 20 is installed on the pedestal 41 so that the laser emission port 31B coincides with the center position of the pedestal 41.

On the pedestal 41, there are three parts around the laser device 20.
The support member 42, which is arranged at a predetermined interval at a certain position, has the bottom portion 4
2A is bent at a right angle and welded. Support member 42
A notch 42B is provided in the upper part of the main body case 39, and a support member 39A protruding from the outer periphery of the main body case 39 accommodating the laser oscillator 31 is fitted therein, thereby supporting the main body case 39. Further, on the support member 42, screws 43A and 43B are screwed into a notch 42B and a screw hole 42C formed in the lower portion thereof, respectively. This screw 4
The main body case 39 is finely adjusted by 3A and 43B so that the main body case 39 is installed on the pedestal 41 substantially vertically, and the main body case 39 is fixed to the insertion jig 40.

Peripheral portion 41B on the base 41 of the insertion jig 40
The guide members 44 are arranged at three locations at equal intervals and are welded to the peripheral portion 41B of the pedestal 41. Guide member 4
The lower end of 4 penetrates the base 41 and supports the insertion jig 40 as a tripod of the base 41. Further, the hanging wires 21 are attached to the wire holes 44A formed in the guide member 44 by the fasteners 45, respectively, whereby the insertion jig 40 on which the laser device 20 is mounted is attached to the inner wall of the guide pipe 9. It is hung down by the hanging wire 21 so as to trace. As a result, the laser device 20 has the laser emission port 3
1B is installed in an upright state substantially vertically with respect to the bottom 8A of the guide pipe 8 or the bottom 9A of the guide pipe 9, respectively.

3 attached to the guide member 44 here
One of the two suspension wires 21 is set to be short, and
The position where the two wires are bound together is set not to be located above the laser emission port 31B located at the center of the pedestal 41. This prevents the laser beam L1 emitted from the laser emission port 31B from being interrupted by the suspension wire 21 in the optical path.

The base 41 has three air vent holes 46 at three positions.
Has been opened. The air vent hole 46 allows the air trapped between the pedestal 41 and the bottom portion 9A to escape when the insertion jig 40 is inserted into the guide pipe 8 or 9, so that the insertion jig 40 is moved to the pedestal 41 and the bottom portion 9A. The air enclosed with 8 or 9A is released, and air resistance is reduced, so that the suspension wire 21 unreeled from a winch (not shown) can be smoothly landed on the bottom 8A or the bottom 9A. Has been done.

Here, as shown in FIG. 11, a guide pipe 8 is installed on the inner side surface of the guide box 5 along the vertical direction of the guide box 5, and the central coordinate position B of the light receiving sensor 23 of the laser light detecting section 22 is set. It is arranged so as to be located right above the center O of the opening 8B. Here, the laser light L1 emitted vertically upward from the bottom portion 8A of the guide pipe 8 is detected by the light receiving sensor 23, and XY from the position B of the laser light L1 emitted from the position C of the laser emission port 31B is detected. The vertical of the guide box 5 can be measured by measuring the displacement of the insertion tube with respect to the center line G3 on the coordinates. Furthermore, based on this measured displacement, the guide box 5 can be installed vertically using the jack 16. These four jacks 16 are arranged around the guide box 5 in correspondence with the XY coordinates of the light receiving sensor 23 above the guide pipe 8, and the coordinates on the monitor 29 are displaced in the X axis direction and the Y axis direction. The position of the guide box 5 can be adjusted according to ΔX and ΔY.

Further, as shown in FIG. 12, the guide pipes 9 are installed along the side surface of the true column 4 in parallel at predetermined intervals L. At this time, the horizontal movement direction and the horizontal movement distance of the center line G2 of the guide pipe 9 (hereinafter referred to as the movement amount) become the same amount as the movement amount of the center line G1 of the false column 4. The center O of the opening 9B of the guide pipe 9 is set vertically below the position B of the coordinate center on the light receiving sensor 23 of the laser light detector 22. That is, when the true column 4 is hung vertically downward from the position A of the column cradle 5, the laser emission port 31B of the laser device 20 installed on the bottom 9A of the guide pipe 9 is provided.
The position C is located vertically below the position B.

Here, in the guide pipe 9 installed on the side surface of the true post 4, the center line G1 of the true post 4 suspended from the excavation hole 2A of the post stand 2 on which the laser beam detector 22 is installed is set. Assuming that the position A of the excavation hole 2A on the horizontal plane 2B is the origin coordinate ( ₀ , ₀ ) and the center coordinate (X ₀ , Y ₀ ) of the light receiving sensor 23 located on the column pedestal 2 is the position B, the position A The horizontal distance L to the position B is

[Equation 1] Is obtained by

Further, the distance from the position B to the bottom portion 9A of the guide pipe 9 located vertically below is defined as d, and the bottom portion 9 is further defined.
Assuming that the height from A to the laser emission port 31B is h, the distance d'from position B to position C is

[Equation 2] Represented by Here, the guide pipe 9 has a horizontal distance L from the position C to the position D when the position D is located vertically below the position A on the center line G1 of the true column 4 and has a distance d '. As described above, the fixing members 10 and 11 are installed on the true post 4. As a result, the laser beam L1 emitted vertically upward from the laser emission port 31B installed in the vertical guide pipe 9 is applied to the position B on the light receiving sensor 23. That is, the displacements ΔX and ΔY in the X-axis direction and the Y-axis direction on the XY coordinate at the position D are the XY at the position C.
The displacements coincide with the displacements ΔX and ΔY in the X-axis direction and the Y-axis direction on the coordinate, and further, the X-axis direction and the Y on the XY coordinate at the position B.
It becomes equal to the displacements ΔX and ΔY in the axial direction, whereby the displacements ΔX and Δ on the XY coordinate of the position D on the light receiving sensor 23.
Y is detected as displacements ΔX and ΔY on the XY coordinate at the position B.

Here, the inclination Δa of the true column 4 is determined by the position D (X
_10, the displacement ΔX in X-Y coordinates in the Y _10), the following equation movement amount [Delta] L _D from ΔY horizontal direction H

(Equation 3) From the movement amount ΔL _D and d ′

[Equation 4] Obtained by Since d ′ is sufficiently long and the movement amount ΔL _D is sufficiently small here, the distance from the position A to the position D and the distance from the position A to the position D to which the movement amount ΔL _D is added are approximately Considered the same.

In the above structure, the laser device 20 is inserted into the guide pipe 8 installed on the inner side surface of the guide box 5, and the vertical displacements ΔX and ΔY of the guide box 5 detected by the laser light detector 22 are detected. Jack 16
When the guide box 5 is vertically installed in the pile hole EH by this adjustment, the true pillar 4 is built in the pile hole EH by being guided by the guide box 5. A guide pipe 9 is fixed in parallel to the true post 4 suspended from the post stand 2 along the outer peripheral side surface of the true post 4, and the center position O of the opening 9B of the guide pipe 9 is the light receiving sensor. 23
The position of the light receiving sensor 23 is set so as to be located vertically below the center coordinate position B of.

When the guide pipe 9 is fixed, the column pedestal 2
The laser device 20 placed on the insertion jig 40 is suspended by the suspension wire 21 on the bottom portion 9A of the guide pipe 9. Visible laser light L1 is emitted vertically upward from the laser emission port 31B from the suspended laser device 20, and the visible laser light L1 is received by a light receiving sensor 23 installed on the column support 2. It

At this time, as shown in FIG. 13, when the true posts 4 are built with an inclination of Δa with respect to the vertical direction, they are located vertically below the hanging position A on the center line G1 of the true posts 4. The position D of the predetermined distance d ′ causes the displacements of ΔX and ΔY in the X-axis direction and the Y-axis direction, respectively, in the XY coordinate.
As a result, the true post 4 is at the position D ′ in the horizontal direction H from the position D.
A shift of the movement amount ΔL _D occurs. At this time, the position C of the laser emission port 31B of the laser device 20 installed in the guide pipe 9 moves to the position C'with the inclination of the true column 4. Where X- from position C to position C '
The displacements ΔX and ΔY in the X-axis direction and the Y-axis direction in the Y coordinate and the movement amount ΔL _C in the horizontal direction H associated therewith are equal to the displacements ΔX and ΔY from the position D to the position D ′ and the movement amount ΔL _D , respectively. Displacement and movement amount.

As a result, when the true post 4 is built vertically, the visible laser light L1 received at the position B on the light receiving sensor 23 is displaced by the same value as when it reaches the position C'from the horizontal position C. The light is received at a position B ′ that is deviated by ΔX and ΔY. Accordingly, if the guide boxes 5 are moved so as to cancel the detected displacements ΔX and ΔY by using the respective jacks 16 installed around the guide box 5 along the axial direction of the XY coordinates, the true column will be obtained. 4 can be adjusted vertically.

The position B on the light receiving sensor 23 at this time
If ′ is the coordinates (X ₁₀ , Y ₁₀ ), the movement amount ΔL _B from position B to position B ′ is

(Equation 5) And then

(Equation 6) Thus, the horizontal movement amount ΔL _{D of the} true column 4 can be obtained. Furthermore,

(Equation 7) Thus, the inclination Δa of the true column 4 can be obtained.

In this way, the irradiation position of the visible laser light L1 detected on the light receiving sensor 23 is on the XY coordinates of the monitor 29 of the personal computer 25, and the origin coordinates (X ₀ , Y).
₀ ) together with position D ′ and displacement Δ from position D to position D ′
Numerical values of X and ΔY are displayed. As a result, the displacements ΔX and ΔY of the true column 4 equivalent to the inclination of the guide pipe 9 are immediately detected, and the vertical build-up of the true column 4 can be easily adjusted based on the displacements ΔX and ΔY. . Further, the inclination Δa of the true post 4 can be immediately calculated by the personal computer 25.

According to the above construction, the laser light L1 emitted vertically upward from the bottom portion 9A of the guide pipe 9 installed in parallel along the side surface of the true column 4 is received by the light receiving sensor 23. By doing so, the guide pipe 9
The vertical deviation of the true post 4 parallel to the vertical axis can be immediately detected as the displacements ΔX and ΔY in the XY coordinates. On this occasion,
In particular, even when the position where the vertical direction is measured is deep in the foundation pile hole, the operator can get down to the foundation pile hole and measure the displacement of the true column 4 in the horizontal direction H. Can improve. Further, the measurement result is immediately sent to the personal computer 25, the displacements ΔX and ΔY are displayed on the monitor 29, and the inclination is calculated, so that the time required for the vertical measurement and adjustment can be greatly shortened.

In the above embodiment, the case where the laser device 20 is hung on the bottom of the guide pipe after the guide pipe 9 is installed on the side surface of the true column is described, but the present invention is not limited to this. Alternatively, the guide pipe may be installed on the side surface portion of the false column to be measured with the laser device 20 originally arranged at the bottom portion of the guide pipe.

Further, in the above-mentioned embodiment, the case where the guide pipe for guiding the laser device 20 to the lower portion of the false column 4 is one-stage type has been described, but the present invention is not limited to this, and the object to be measured is not limited thereto. It may be a two-stage type according to the length of the product. That is, as shown in FIG. 14, the cylindrical guide pipe 44 is constructed by joining two stages of pipes 44A and 44B. The joint portion 45 of the guide pipe 44 has a flange shape, and a water-stopping packing 46 is inserted in a connecting portion between the flanges and is joined by a bolt 47. Since the guide pipe 44 has the two-stage structure as described above, the guide pipe 44 can be adjusted to a desired length according to the length of the true column 4.

A plurality of skirts 48 made of triangular plate-shaped steel material are installed above the flange of the joint portion 45.
By installing this skirt 48, a crane (not shown) is provided after the vertical measurement and adjustment of the true post 4 are completed.
Thus, when the guide pipe 44 is lifted up and pulled out, the wire 11A of the fixing member 11 can be easily cut. After the wire 11A is cut, the guide pipe 44 having the flange at the joint can be easily recovered by slightly shifting the position of the guide pipe 44 laterally.

As a result, the applicable range of the length of the false column subject to vertical measurement and the range of depth of the measurement position can be expanded. Further, if the guide pipe is disassembled and the length of the guide pipe is shortened, it is possible to obtain convenience for carrying the guide pipe. Furthermore, the number of stages of the guide pipe may be increased according to the length of the column to be measured, and if several types of pipes with different lengths are prepared, the range of the measurement target can be set even finer. it can.

Further, in the above-mentioned embodiment, the guide box 5 and the true column 4 are provided by the guide pipe 8 installed inside the guide box 5 and the guide pipe 9 installed parallel to the side surface of the true column 4. However, the present invention is not limited to this, and by accurately guiding the guide box 5, the vertical axis of only the guide box 5 is measured and adjusted to obtain the true column. 4 may be vertically guided and built.

Further, in the above-mentioned embodiment, the case where the vertically built object is the true pillar which is the pillar of the underground structure of the building has been described, but the present invention is not limited to this, and for example, the pillar on the ground. Alternatively, the present invention may be applied to a case where a wall or the like is built vertically, that is, the present invention can be applied to a case where a pillar or a wall is built in the vertical direction between two points separated by a predetermined distance.
