Seismic reinforcement method of seismic reinforcement structure and existing buildings of existing buildings

摘要

The present invention, while satisfactorily ensuring the workability of mounting the steel material to a plurality of shaft member plugged into existing buildings, in existing buildings where a decrease in the integrity of the shaft member and the concrete body of the steel can be suppressed to provide a seismic reinforcement method of seismic reinforcement structure and existing buildings. Seismic reinforcement structure of An existing building includes a plurality of shaft member 22 tip to the existing building is plugged in, the steel having a plurality of through holes 28 base end portion of the multiple possible loosely fits of shaft member 22 23 If, is attached to the proximal end of the shaft member 22A which is inserted into the insertion hole 28A, a clamping portion 31 for clamping the steel material 23, at the proximal end of the shaft member 22B which is inserted into the insertion hole 28B, from the steel 23 also includes a stop portion 34 to exit is provided in a position closer to the base end, the concrete body 24 to be integrated with the existing building comprises a steel 23 inside the. .BACKGROUND
