PROBLEM TO BE SOLVED: To provide a temporary support structure of a building capable of supporting upper building load without needing to reinforce existing columns and beams while allowing easy attachment/detachment and also diversion of a support tool. SOLUTION: First bearing parts 5u, 5u are mounted to both side faces of an upper part of a column 8, and second bearing parts 5d, 5d are mounted to both side faces of a lower part of the column 8. A pair of link mechanisms 2, 2 connecting the first bearing parts 5u, 5u and second bearing parts 5d, 5d are mounted symmetrically with respect to the column center. The link mechanisms 2, 2 are composed of the first bearing parts 5u, 5u, the second bearing parts 5d, 5d, first arms 2u, 2u with one ends turnably supported to the first bearing parts 5u, 5u, second arms 2d, 2d with one ends turnably supported to the second bearing parts 5d, 5d, and connecting parts 3, 3 turnably connecting the other ends of the first arms 2u, 2u to the other ends of the second arms 2d, 2d. The connecting parts 3, 3 are connected to each other by a prestressed concrete steel bar 4. COPYRIGHT: (C)2005,JPO&NCIPI
