INSTALLATION METHOD OF FRAME BODY HAVING COLUMN

PROBLEM TO BE SOLVED: To provide an installation method of a frame body having columns opposite to each other in the span direction and a beam disposed between the columns so as to form, for example, a gate shape, which includes sliding the constructed frame body in the span direction and fixing a column base to a fixing part at an installation position, such that the column base of the column to be fixed is not subject to a pull-out force during sliding for securing stability of the frame body (block) during sliding and that the column is installed in an original stress state when fixed at the fixing position after sliding.SOLUTION: A frame body 1 includes columns 2 and 3 opposite to each other and a beam 4 disposed between the columns 2 and 3, as fundamental elements. At least the column 3 which is at least one of the columns 2 and 3 opposed to each other of the frame body 1 is composed of column components 31 and 32 arranged in parallel with the span direction. In a state that the leg part of the column component 32 which is one of the column components subject to a vertical upward force in a fixed state at the installation position of the column 3 which is at least one of the columns is floated, the frame body 1 is slid while the columns 2 and 3 opposite to each other are left on tracks 5 and 5. The column components 31 and 32 arranged in parallel of the column 3 which is one of the columns having the column component 32 in the floated state are then lowered, and subsequently the other column 2 (column component 21) is lowered.
