[Construction method of frame structure]
Next, a construction method of the frame structure will be described.
<1> Placing Support Pile As shown in FIG. 5 (a), the support pile 10 is driven at a predetermined interval.

<2> Suspension set of horizontal truss As shown in FIG. 5B, the prefabricated horizontal truss 20 is brought into the site, lifted with a crane or the like and dropped from above the support pile 10, and the horizontal truss 20 A plurality of sheath pipes 40 attached to the outer side of the support piles 10 adjacent to each other.

Since the sheath tube 40 is formed to have a larger diameter than the support pile 10 and a gap for position adjustment is formed between the members 10 and 40 due to the difference in diameter, the manufacturing tolerance of the horizontal truss 20 and the support pile Even if there is some error in the placement accuracy of 10, the horizontal truss 20 can be smoothly suspended and set across the plurality of support piles 10 without the sheath tube 40 interfering with the support piles 10.
The sheath tube 40 and the support pile 10 are in an unfixed state due to the difference in diameter. Therefore, the horizontal truss 20 is fixed to the support pile 10 by a simple operation described below.

<3> Fixing Pile Hold Tool As shown in FIG. 5C, the suspended truss 20 is kept suspended by a crane or the like, and the pile hold tools 50 and 50 are fixed to the support pile 10. The lower connecting device 30 supports the weight of the horizontal truss 20, and the upper connecting device 30 restrains the upward displacement of the horizontal truss 20.

That is, by fastening the fastening bolts 56 shown in FIGS. 6 and 7 and gripping them on the peripheral surfaces of the chuck portion 51 and the support pile 10, the pile holding tools 50 and 50 are fixed to a predetermined height of the support pile 10.
Since the pile holding tool 50 is only gripped and fixed to the peripheral surface of the support pile 10, a screw hole for screwing a bolt into the support pile 10 itself is formed, or a protrusion is integrally projected. There is no need for special processing.

<4> Fixing of the sheath pipe and the pile holding tool In FIGS. 6 and 7, the center of the pile holding tool 50 fixed to the support pile 10 is always in agreement with the center O ₁ of the support pile 10. center O ₂ of the sheath pipe 40 which is exterior to 10, the support not necessarily coincide with the center O ₁ of the pile 10, and or there is an error in punching設精of the horizontal bridging support piles 10 or have manufacturing tolerances in the truss 20 In some cases, the centers O ₁ and O ₂ of the both are displaced.

In the present invention, one of the bolt holes 45 and 54 formed in the flanges 43 and 52 of the sheath tube 40 and the pile holder 50 is formed as a long hole directed in the frame axis direction of the frame structure or in the orthogonal direction of the frame axis. Thus, even if the centers O ₁ and O _{2 of the two} do not coincide, the connection between the sheath tube 40 and the pile holder 50 can be easily fixed with the connecting bolt 57.
That is, the elongated bolt hole 45 absorbs the deviation (bias) of the centers O ₁ and O ₂ of the frame structure in the frame axis direction or the orthogonal direction of the frame axis.
In other words, both the centers O ₁ and O _{2 of} the support pile 10 and the sheath tube 40 due to the manufacturing tolerance of the horizontal truss 20 and the placement error of the support pile 10 due to the long hole and the position adjusting gap. It is possible to absorb the deviation.

  The frame structure constructed in the above process is loaded between each support pile 10 and the horizontal truss 20 via the connection device 30 while leaving a gap formed between the sheath tube 40 and the support pile 10. Can be firmly connected so as to be able to communicate with each other.

<5> Other Assembling Methods of Pile Hold Tool Note that the pile hold tool 50 of the connection device 30 may be temporarily attached with the connecting bolt 57 and slidably assembled to the upper and lower portions of the sheath tube 40.
If the pile holding tool 50 is assembled to the sheath pipe 40 in advance, the pile holding tool 50 can be externally mounted on the support pile 10 together with the sheath pipe 40 when the horizontal truss 20 is suspended, and then the pile holding tool 50 is supported by the support pile. After fixing to 10, the connection bolt 57 that has been temporarily fixed is tightened to fix between the sheath tube 40 and the pile holder 50, thereby shifting the center O ₁ , O ₂ between the support pile 10 and the sheath tube 40. The horizontal truss 20 can be fixed to the support pile 10 while absorbing.

<6> Other Combinations of Long Holes FIG. 8 shows a form in which the bolt holes 45 and 54 formed in the flanges 43 and 52 of the sheath tube 40 and the pile holder 50 are both long holes.
As shown in the figure, by crossing the elongated bolt holes 45 and 54, the displacement absorption direction when the sheath tube 40 and the pile holding tool 50 are bolted together is the frame axial direction of the frame structure and the frame structure. There is an advantage that the shift absorption range becomes wider in the direction perpendicular to the axis.

[Removal method of frame structure]
When the purpose of use of the frame structure is completed, the frame structure can be removed by a simple operation by simply lifting the horizontal truss 20 after removing the pile holding tool 50 constituting the connection device 30 from the support pile 10. it can.
