PROBLEM TO BE SOLVED: To provide an existing-column cutting and holding method which can reduce damage to an existing column, which can reduce labor and costs, associated with construction work, and which can enhance the safety of work in a narrow space; and to provide a load bearing member. SOLUTION: In this method for cutting and holding the existing column 1 of a building, the existing column 1 is arranged between opposed apex-angle portions 30 and 32 of inclined planes of a pair of brackets 12 and 14 having the end inclined planes 24 and 26; a deformation-resistant and load-resistant member 16 is arranged between the end inclined planes 24 and 26 and the existing column 1; apex angle-side lateral surfaces 34 and 36 are bound together by a binding means 18 which detours around the existing column 1 in the state of sandwiching the existing column 1 in between; longitudinal-load bearing jacks 80 and 82 for the existing column 1 are arranged on the apex angle-side lateral surfaces 34 and 36 of the brackets 12 and 14; and the existing column 1 on the sides of the apex angle-side lateral surfaces 34 and 36 of the brackets 12 and 14 is cut. The load bearing member 10 is used for the existing-column cutting and holding method. COPYRIGHT: (C)2009,JPO&INPIT
