(Advantageous Effects of Invention) The support structure for a support according to the present invention is such that the lower end of the support inserted into the tubular body is clamped by a plurality of adjusting bolts that are horizontally screwed through the tubular body from the outside. The position of the pillar can be adjusted by supporting the pillar and changing the screwing amount of the adjusting bolts corresponding to the front and rear sides in the direction of adjustment in inverse proportion. (Embodiment) An embodiment of the present invention will be described below with reference to FIGS. That is, when supporting the support P, the foundation (second
The cylindrical body 1 is provided at the center of the bottom of the basic hole H formed in B). The cylindrical body 1 in this embodiment has a square pole shape by combining two plates 2 bent into an L shape. Both plates 2 and 2 are the same part. The plate 2 has a flange 2c formed at a side end of one piece 2a in a state where both pieces 2a, 2b are erected.
A bolt through hole 2d and a circular opening 2e are formed vertically near the upper end of 2b, and both pieces 2a, 2
An anchor through hole 2f is formed on each of both sides of the bottom end of b. At this time, in both pieces 2a and 2b, the height of the bolt through hole 2d is the same, but the height of the opening 2e and the anchor through hole 2f has a dimensional difference corresponding to the diameter of the anchor through hole 2f. It is provided. In addition, a nut 3 is coaxially fixed to the inner portion of the cylinder of each bolt through hole 2d. In both the plates 2 and 2, the abutting portion of the flange 2c and the other piece 2b of the mating plate is coupled by a plurality of screws 8 to form a cylinder body 1, and the bolt facing hole 2d is formed between the facing pieces. , Opening 2e and anchor through hole 2f
Are facing each other. The pillar P in this embodiment is formed by fitting and fixing a reinforcing member 5 having a rectangular cross section inside the lower end of a main body 4 having a rectangular cross section. The reinforcing member 5 has an upper through hole 5 that communicates with a portion protruding from the main body portion 4 between facing surfaces.
Two a and two lower through holes 5b are formed. At this time, the through holes 5a, 5b provided on one of the opposing surfaces
And the through holes 5a and 5b provided on the other facing surface have the same height difference as the anchor through hole 2f described above.
The lower through hole 5b is provided at a height position corresponding to the opening 2e. In order to support the support P, first, the cylindrical body 1
The anchors 6 made of, for example, deformed steel bars are passed through the respective anchor through-holes 2f, and the four anchors 6 form a cross beam so as to pass through the cylindrical body 1, and the cylindrical body 1 is positioned at the center of the bottom portion of the foundation hole H. Then, concrete C is poured into the outside of the cylinder 1 to a height slightly lower than the opening 2e. Further, an adjusting bolt 7 that is screwed into the nut 3 is provided in each bolt through hole 2d. At this time, the four adjusting bolts 7 are screwed into the cylindrical body 1 from the outside at 90 degree intervals in the horizontal direction. Next, when the concrete C is hardened, the lower end of the pillar P is inserted into the center of the tubular body 1, and each adjustment bolt 7 is tightened to bring the tip into pressure contact with the pillar side surface (reinforcing member 5). The anchors 6 are passed through the openings 2e and the lower through holes 5b so that the two anchors 6 cross each other and penetrate the cylindrical body 1 and the support P. Thereby, the support P
Are sandwiched by the adjusting bolts 7 from all sides, and are self-supporting and temporarily supported. Therefore, there is no need to use a projecting rod that hinders other work. When adjusting the position of the column P along with connecting a girder (see FIG. 4) or the like to the upper end of the column P, the adjustment bolt 7 which is the adjustment direction is loosened and at the opposite side. Tighten the adjusting bolt 7 of.
