The mounting bolt 32 is fixed upward on the upper surface of the horizontal piece 35 c, and the mounting bolt 32 projects upward from the steel pipe foundation pile 20.

The pair of level mounts 40 are formed with bolt insertion portions, for example, long holes 41 in the longitudinal direction, near both ends in the longitudinal direction.
The mounting bolt 32 is inserted into the long hole 41, the lower surface of the level mount 40 abuts against the lower nut 33, and the upper nut 34 is pressed against the upper surface of the level mount 40 to fix the level mount 40 to the mounting bolt 32. The level mount 40 is located above the steel pipe foundation pile 20.
Since it is like this, by adjusting the position of the lower nut 33, the attachment height of the level mount 40 can be adjusted and it can position in a height direction. Since this operation is performed above the steel pipe foundation pile 20, the operation is easy and can be positioned in the height direction with high accuracy.
An abutting tool 42 is attached to the pair of level mounts 40 so that the position thereof can be adjusted in the longitudinal direction (Y direction) of the level mounts 40.
For example, a long hole 43 is formed in the abutting tool 42, a bolt 45 is inserted into the hole 44 and the long hole 43 of the level base 40, and a nut 46 is screwed to the bolt 45 and attached.

As shown in FIG. 2, the positioning cross member 50 is positioned in the height direction on one side vertical plate 11 a and the other side vertical plate 11 b of the hanging jig 10, and is attached parallel to each other and horizontally. Then, it is placed on the level mount 40 and positioned and fixed in the Y direction. For example, the positioning cross member 50 has a cross-sectional shape of a horizontal piece 50a and a vertical piece 50b, and a first hole 51 is formed in the horizontal piece 50a, and a second hole 52 is formed in the vertical piece 50b. A bolt 55 is inserted from the second hole 52 through the hole 19 of the one side vertical plate 11a and the other side vertical plate 11b, and a nut 56 is screwed and attached.
A bolt 53 is inserted through the first hole 51 and the hole 41 of the level mount 40, and a nut 54 is screwed to attach the positioning cross member 50 to the level mount 40.
The positioning cross member 50 is located above the steel pipe foundation pile 20 and is easy to perform the positioning and fixing operations described above.
3 and 4, the positioning cross member 50 is shown and the hanging jig 10 is not shown. However, as will be described later, the positioning cross member 50 attached to the hanging jig 10 is actually used. It is mounted on the level mount 40.

Next, the operation | work which installs the member 1 for column fixation in the steel pipe foundation pile 20 is demonstrated.
First, an operation of attaching the positioning cross member 50 to the hanging jig 10 will be described.
As shown in FIG. 5, the surface plate 60 is horizontal.
For example, height adjustment bolts 61 are screwed into the four corners of the surface plate 60, and the heights of the four corners of the surface plate 60 are adjusted by the height adjustment bolts 61, and the first level 62 moves in the X direction. The horizontal level is confirmed by the second level 63 and the level in the Y direction is determined to be horizontal.
As shown in FIG. 6, the lower surface plate 12 of the hanging jig 10 is placed on the surface plate 60 and the hanging jig 10 is placed upright.
As a result, the lower surface plate 12 becomes horizontal.
Width H ₁ one side vertical plate 11a and side portions that bordering the connecting longitudinal plate 11c of the other side vertical plate 11b of Tsukomi jig 10 described _above, H ₂ was measured, the width H _1, H _{If the two} are different, the nut 18 screwed into the bolt 17 is tightened and loosened as described above so that the width dimensions H ₁ and H ₂ are the same, and the pair of positioning cross members 50 can be attached in parallel. .
That is, when the hanging jig 10 is H-shaped steel or the like, the aforementioned width dimensions H ₁ and H ₂ may differ depending on the strain of the H-shaped steel. In this case, the pair of positioning cross members 50 are parallel to each other. Therefore, an error may occur in positioning described later, so that the width dimensions H ₁ and H ₂ are made the same as described above.
The mounting height position of the positioning cross member 50 of the hanging jig 10 is determined according to the embedding depth of the column fixing member 1 on the basis of the upper surface (that is, the horizontal plane) of the surface plate 60, as described above. Then, the positioning cross member 50 is fixed to the predetermined height position in parallel and attached.
In addition, since the embedding depth of the column fixing member 1 is variously different, the plurality of holes 19 are formed in the above-described longitudinal agent 11 on the one side longitudinal plate 11a and the other side longitudinal plate 11b with the positions shifted in the height direction.
The adjustment of the mounting height position of the positioning cross member 50 described above is performed, for example, as shown in FIG. 6, the distance S ₁ between the bottom surface of each positioning cross member 50 in the longitudinal direction and the top surface of the surface plate 60, S ₂ is measured and adjusted so that the distances S ₁ and S ₂ have predetermined values.
Further, as shown in FIG. 6, the pair of positioning cross members 50 is parallel to the dimension L ₁ between one end in the longitudinal direction of the pair of positioning cross members 50 and the dimension L ₂ between the other ends. It was measured, to confirm on whether the dimension L ₁ and dimension L ₂ are identical.

  Thereafter, the hanging jig 10 and the column fixing member 1 are connected as shown in FIG.

Next, attachment of the positioning jig will be described.
First, the attachment jig 30 is positioned and attached to the upper end portion of the steel pipe foundation pile 20 using the panel ruler 21.
For example, as shown in FIGS. 7A and 7B, a mark a that matches the center X in the X direction is attached to the upper end surface 20 a of the steel pipe foundation pile 20.
And as shown to Fig.8 (a), (b), the panel ruler 21 is mounted in the upper end surface 20a of the steel pipe foundation pile 20, and the X direction reference line 23 is match | combined with the said mark a, and the panel ruler 21 is used. Position in the Y direction.
Thereafter, the mounting jig 30 is attached to the pair of Y-direction reference lines 24 of the panel ruler 21. Thereby, the attachment jig 30 is positioned in the X direction and the Y direction.
The above-mentioned center in the X direction is a center line passing through the center of the steel pipe foundation pile 20 in the X direction, and is obtained using a light wave transit or the like, and is marked with a mark a. When there are a plurality of steel pipe foundation piles 20 in the X direction, the center line in the X direction is made continuous over each steel pipe foundation pile 20.

The mounting jig 30 is mounted on both sides of the panel ruler 21 so that the mounting bolt 32 matches the Y-direction reference line 24.
Since the X-direction reference line 23 of the panel ruler 21 passes through the pair of notches 22, the panel ruler 21 can be positioned by matching the pair of notches 22 with the mark a, and the X-direction reference line The X-direction reference line 23 can also be formed by the notch surfaces 22 a of the pair of notch portions 22 without continuously attaching 23 to the surface of the panel ruler 21.
The pair of Y-direction reference lines 24 may be attached after the panel ruler 21 is positioned and placed.

When the attachment jig 30 has been attached as described above, as shown in FIGS. 9A and 9B, the pair of level mounts 40 are placed on the attachment jig 30 in a horizontal posture at a predetermined height. Install each one.
For example, the long holes 41 of the level mount 40 are respectively inserted into the mounting bolts 32 of the two mounting jigs 30 adjacent to each other in the Y direction on both sides in the X direction to contact the lower nut 33, and the lower nut 33 is tightened and loosened. By moving up and down, the height of the level mount 40 is adjusted to be horizontal at a predetermined same height, and the upper nut 34 is screwed and fixed.
Thereby, the pair of level mounts 40 are positioned in the X direction.

Since the mounting bolt 32 is inserted into the long hole 41 of the level mount 40 described above, the mounting bolt 32 can be inserted in a different position in the longitudinal direction of the level mount 40, and the mounting jig 30 is attached to the upper end portion of the steel pipe foundation pile 20. Since it is sandwiched and attached, the attachment jig 30 can be attached to any position of the steel pipe foundation pile 20.
Therefore, the mounting position of the level mount 40 can be arbitrarily changed, and the level mount 40 can be mounted on the steel pipe foundation piles 20 having different sizes.

When the pair of level mounts 40 is completely attached as described above, the abutting tool 42 is positioned and attached in the Y direction.
For example, as shown in FIGS. 9A and 9B, a ruler 47 with a magnet is placed across the pair of level mounts 40, and the front and rear of the outer surface 47a of the ruler 47 are viewed in transit. issue X _2. That is, the X direction passing through the above-mentioned mark a and the center X are separated by a predetermined distance from the center X ₂ and the outer surface 47a of the ruler 47 are made to coincide, and the inner side surface 47b of the ruler 47 is aligned in the X direction X Match ₁
The abutment tool 42 is placed on the inner surface 47 b of the ruler 47 for positioning, and fixed with bolts and nuts 45 and 46. After this, the ruler 47 is removed.

As described above, the hanging jig 10 to which the column fixing member 1 is attached is suspended by a crane or the like, and the column fixing member 1 and the hanging jig 10 are suspended in the steel pipe foundation pile 20 to be suspended. Ten positioning cross members 50 are placed on a pair of level bases 40, and one of the positioning cross members 50 is in contact with the abutting tool 42 and positioned in the Y direction as shown in FIGS. 10 (a) and 10 (b). To do.
The distance from the reference point in the X direction to the hanging jig 10 is measured by transit, and the hanging jig 10 is moved along the level frame 40 through the positioning cross member 50 so as to be a predetermined distance in the X direction. To position in the X direction.
That is, by positioning the suspending jig 10 in the X direction and the Y direction, the column fixing member 1 is positioned and suspended in the steel pipe foundation pile 20 in the X direction and the Y direction.

When positioning the hanging jig 10 as described above, the square holes 49 of the panel ruler 48 are inserted into the vertical member 11 of the hanging jig 10 as shown by phantom lines in FIGS. 10 (a) and 10 (b). Based on the center line b of the panel ruler 48 in the X direction and the line c in the X direction separated from the center line b by a predetermined distance in the Y direction, the hanging jig 10 is repositioned in the Y direction. To do. The line c is consistent with previously described X _2, Y direction one of the inner surfaces of the rectangular hole 49 matches the previously described X _1.
In the X direction, the panel ruler 48 is perpendicular to the center line b in the X direction and is centered in the Y direction, and the center line d in the Y direction is separated from the center line d by a predetermined distance in the X direction. Position it.
That is, the center line d to match the base line Y in the Y direction, the X direction using the transit to match the street Y ₁ and line e of the street in the Y direction center Y and a predetermined distance away Y direction Position it. This line e coincides with one inner surface of the square hole 49 in the X direction.
The panel ruler 48 is formed with a notch 48 a for viewing the abutting tool 42 and the positioning cross member 50.
The positioning by the panel ruler 48 is the confirmation of the positioning described above, and therefore it is not always necessary to perform the positioning.

By positioning as described above, the column fixing member 1 is suspended in the steel pipe foundation pile 20 in the X and Y directions at a predetermined height position as shown in FIG.
In this state, the pair of positioning cross members 50 are fixed to the pair of level mounts 40, respectively.
And concrete 60 is laid in steel pipe foundation pile 20, and as shown in Drawing 11, pillar fixing member 1 is embedded by predetermined depth. At this time, if the column fixing member 1 is completely embedded, it is difficult to fix the column. Therefore, an upper portion of the column fixing member 1, for example, a portion from the upper surface to 50 mm is projected upward from the concrete 60, and a lower portion than that is projected. It is embedded so that the positioning protrusions 2 and the screw holes 3 protrude above the concrete. .

When the curing period of the concrete 60 elapses, the suspension jig 10 and the column fixing member 1 are separated, and the suspension jig 10, the level mount 40, and the mounting jig 30 are removed to fix the column in the steel pipe foundation pile 20. Installation of member 1 is completed.
The bolt 15 is loosened to separate the suspension jig 10 and the column fixing member 1 described above, but it is difficult for a person to enter the steel pipe foundation pile 20 and loosen the bolt 15, so that FIG. The bolt 15 is loosened from above the steel pipe foundation pile 20 by using a tool comprising a ratchet wrench 61 and a long box 62 shown in FIG.
At this time, since the ratchet wrench 61 and the box 62 may interfere with the one side vertical plate 11a and the other side vertical plate 11b of the vertical member 11 of the hanging jig 10, the notch portion 16 is formed as described above. There is no interference.

Next, an operation for installing the pillar will be described.
As shown in FIGS. 12, 13, and 14, the column 70 has an H-shaped cross section with one vertical plate 71, another vertical plate 72, and a connecting vertical plate 73, and a plate 74 is fixed to the lower end surface.
The plate 74 has a positioning hole 75 and a hole 76 formed therein.
The column 70 is placed in the steel pipe foundation pile 20 and the positioning hole 75 is fitted to the positioning projection 2 to be positioned, and the bolt 77 is screwed into the screw hole 3 from the hole 76 to thereby fix the column 70 to the column fixing member 1. It sticks to.
Thereafter, concrete is cast up to the upper end portion of the steel pipe foundation pile 20, and the column fixing member 1 and the lower end portion of the column 70 are embedded in the steel pipe foundation pile 20 and installed.

When the pillar 70 is installed as described above, a support member for stably supporting the pillar 70 is used.
This support member includes a first support member 80, a second support member 81, a first metal fitting 82, and a second metal fitting 83.
The first support member 80 has a substantially trapezoidal shape having an oblique vertical surface 80a, and the second support member 81 has a substantially triangular shape having an oblique vertical surface 81a.
The first receiving bracket 82 and the second receiving bracket 83 are obtained by fixing flanges 82b and 83b on both side surfaces of the upward U-shaped receivers 82a and 83a, and the flanges 82b and 83b are attached to the steel pipe foundation pile 20.
