PROBLEM TO BE SOLVED: To provide a reaction support member installed in a column upper part used for constructing a building and disassembling an existing building, and a disassembling method of the existing building of using this reaction member.SOLUTION: A support tool installed in a column top part comprises a cylindrical member 4 for storing the column top part, a suspension base 5 for supporting a suspension material 7 by joining to the cylindrical member 4 and a cover-shaped member for blocking up at least a part of an upper part of the cylindrical member 4, and provides a reaction support member 1 capable of releasing the cover-shaped member. A disassembling method of an existing building comprises an initial process of suspending-supporting a work floor skeleton from the reaction support member 1 installed in the column top part, by leaving a column up to a predetermined height of penetrating through an existing floor skeleton, with a floor skeleton of the predetermined floor of the existing building as a work floor skeleton, and with at least a partial column of the building as a column, a disassembling process of disassembling a floor height quantity of the column on its skeleton by descending the work floor skeleton after disassembling the existing building except for the column in a space just under the floor skeleton and a repetition process of the disassembling process.SELECTED DRAWING: Figure 1 |
