External reinforcement structure and a method of reinforcing the existing building of the existing building

摘要

PROBLEM TO BE SOLVED: To provide an outer-equipped reinforcement structure of an existing building, capable of being simply constructed at low cost, and a method for reinforcing the existing building.;SOLUTION: An outer-equipped reinforcement structure of an existing building 30 comprises: horizontal members 31 attached to a periphery of the existing building 30; and a reinforcement frame 10 installed on the outside the periphery of the existing building 30. The reinforcement frame 10 is constituted of: reinforcement columns 11 disposed while penetrating through penetrating parts 32 formed in the horizontal members 31; and reinforcement beams 12 extended from side faces of the reinforcement columns 11 in the direction orthogonal to the reinforcement columns 11. A contact joint member 20 is arranged in the penetrating part 32 so as to abut with the side face of the reinforcement column 11. The outer-equipped reinforcement structure is constructed to be a junction structure which supports the existing building only in the horizontal direction against earthquake horizontal force applied in the material axial direction of the reinforcement beams 12 without making the horizontal members bent and resistant.;COPYRIGHT: (C)2014,JPO&INPIT
