PROBLEM TO BE SOLVED: To provide a seismic reinforcement structure for an existing building and a seismic reinforcement method for an existing building that suppress decline in unity between a plurality of shaft members or a steel member and a concrete body, while maintaining high workability when fitting the steel member on the plurality of shaft members inserted into an existing building.SOLUTION: A seismic reinforcement structure for an existing building includes: a plurality of shaft members 22 having a tip part inserted into the existing building; a steel member 23 having a plurality of insertion holes 28 into which a base end part of the plurality of the shaft members 22 may be loosely inserted; a holding part 31 fitted on the base end part of the shaft material 22A inserted into the insertion hole 28A, for holding the steel member 23; a stopper member 34 disposed on the base end part of the shaft member 22B inserted into the insertion hole 28B, at a location closer to the base end than the steel member 23; and a concrete body 24 enclosing the steel member 23 inside and unified with the existing building.SELECTED DRAWING: Figure 3 |
