REINFORCEMENT STRUCTURE OF COLUMNAR STRUCTURE
PROBLEM TO BE SOLVED: To provide a reinforcement structure of a columnar structure, easy in installation with a simple structure, without requiring maintenance work, and capable of improving earthquake-resistant performance.SOLUTION: A reinforcement structure 13 reinforces an electric pole 9. A rigidity imparting part 14 imparts rigidity to this electric pole 9 with a clearance Δ between an outer peripheral surface of this electric pole 9 and itself for restraining deformation by vibration of the electric pole 9. When an earthquake occurs, the electric pole 9 vibrates, and when a wire 14a of the rigidity imparting part 14 in the vicinity of a place deformed in a convex shape of the electric pole 9 is pulled, tension of the wire 14a increases. As a result of it, the tension of the wire 14a acts on the electric pole 9 as compressive force, and the wire 14a restrains deformation of the electric pole 9. When the electric pole 9 is deformed in a concave shape by vibration, the wire 14a of the rigidity imparting part 14 in the vicinity of the place deformed in this concave shape deflects. Thus, the tension of the wire 14a of the rigidity imparting part 14 does not act on the electric pole 9 as the compressive force, so that the deformation of the electric pole 9 does not become large.
【課題】構造が簡単で取り付けが容易であり保守作業の必要がなく耐震性能を向上させることができる柱状構造物の補強構造を提供する。【解決手段】補強構造１３は、電柱９を補強する。剛性付与部１４は、電柱９の振動による変形を抑制するために、この電柱９の外周面との間に隙間Δをあけてこの電柱９に剛性を付与する。地震発生時に電柱９が振動して電柱９の凸状に変形した箇所付近の剛性付与部１４のワイヤ１４ａが引っ張られると、ワイヤ１４ａの張力が増加する。その結果、ワイヤ１４ａの張力が圧縮力となって電柱９に作用して、ワイヤ１４ａが電柱９の変形を抑制する。電柱９が振動によって凹状に変形したときには、この凹状に変形した箇所付近の剛性付与部１４のワイヤ１４ａが撓む。このため、剛性付与部１４のワイヤ１４ａの張力が圧縮力となって電柱９に作用することがなく、電柱９の変形が大きくなることがない。【選択図】図２
