COLUMN REINFORCING METHOD AND COLUMN REINFORCING STRUCTURE
PROBLEM TO BE SOLVED: To provide a column reinforcing method and a column reinforcing structure in which seismic reinforcement of a column member such as an electrification column is made possible by easier work.SOLUTION: A column reinforcing structure 100 has an electrification column 10 vertically divided in a portion provided with a second filler 40, and therefore a disconnected portion of the electrification column 10 of the inside of a tubular reinforcing material 20 is plastically deformed on the occurrence of a large-scale earthquake, and thereby the seismic energy acting on the electrification column 10 can be absorbed. Alternatively, the electrification columns 10 of upper and lower sides more than the second filler 40 are surrounded and reinforced by the tubular reinforcing material 20 and a first filler 30, and therefore can resist the large-scale earthquake. Particularly, according to this column reinforcing method, the cutting work of PC steel 11 requiring carefulness as a conventional technology is not performed, but the PC steel 11 is cut every electrification column 10, and the second filler 40 is filled in the gap where the electrification column 10 is divided by the cutting. The column reinforcing structure 100 can be constructed by relatively simple work as stated in the above.SELECTED DRAWING: Figure 1
【課題】より容易な作業で電化柱など柱体の耐震補強を図ることを可能にする柱体補強方法及び柱体補強構造を実現する。【解決手段】柱体補強構造１００は、第２の充填材４０が設けられた部分で電化柱１０が上下に分断されているため、大規模地震発生時には筒状補強材２０の内側の電化柱１０の分断部分を塑性変形させることで、電化柱１０に作用する地震エネルギーを吸収することができる。一方、第２の充填材４０よりも上側と下側の電化柱１０は、筒状補強材２０及び第１の充填材３０で囲われて補強されているため、大規模地震に抗することができる。特に、この柱体補強方法によれば、従来技術のような慎重を要するＰＣ鋼１１の切断作業を行うのではなく、ＰＣ鋼１１を電化柱１０ごと切断し、その切断によって電化柱１０が分断された隙間に第２の充填材４０を充填するという比較的簡便な作業によって柱体補強構造１００を構築することができる。【選択図】図１
