摘要： PROBLEM TO BE SOLVED: To provide an erection adjusting tool for a pillar and a pillar erecting method using the same, which does not deteriorate the use efficiency of work spaces, improve the safety of erection works, shortens a construction period, and enables delicate adjustment in a easy manner. SOLUTION: The erection adjusting tool 1 has an upper mounting steel plate 10 corresponding to an upper erection piece 5, and a lower mounting steel plate 11 corresponding to a lower erection piece 3, wherein the mounting plates are temporarily mounted on the erection pieces, respectively, by screwing down bolts 9 into respective holes and fastening them with nuts. In this manner, the erection adjusting tool 1 is mounted on every side of upper and lower steel pipe pillars 2, 4. Then, while the verticality of the upper steel pipe pillar 4 is checked, the handle 7 of an adjusting bolt 6 is rotated clockwise or counterclockwise in a proper manner to make a wedge 8 on the extremity of the adjusting bolt 6 move forward or retreat in the gap between the upper and lower erection pieces 3, 5 so that the slope of the upper steel pipe pillar 4 is adjusted.

摘要： PROBLEM TO BE SOLVED: To provide a temporary joint method for a column during jack system which is capable of improving the safety of demolition work, of easily corresponding with the column to be jointed, of reducing construction cost. SOLUTION: Angles 6 are installed with anchor bolts 5 on four surfaces of a foundation column 3. Next, at the upper portion of the angles 6, a pair of channel-shaped jointing steel members 4 are jointed with bolts 8 so as to form a steel pipe column, and the joint member 4 is arranged by straddling the vicinity of the column 2 and the foundation column 3. An opening at the lower portion of a pair of jointing steel member 4 which becomes a form of steel pipe column is closed at the upper surface of the angle 6, and an opening at its upper part is covered with a form 9. Within this closed space, mortar grout 12 is filled from a grunt filling hole 11 at the lower portion of the joint steel member 4 and hardened. After hardening of the grout, when the jointing steel member 4 jointed by the bolts is removed, the space between the bottom end of the column 2 and the foundation column 3 is connected with the mortar grout 12.
