MEMBER REPLACEMENT METHOD FOR TRUSS STRUCTURE
To provide a member replacement method for truss structure capable of replacing members with minimum equipment while maintaining the self-standing property of the truss structure.SOLUTION: While attaching a temporary chord member 7 between an upper chord member 1 and a lower chord member 2, the temporary chord member 7 and the upper chord member 1 are connected by a plurality of temporary diagonal members 8 to form a temporary truss. The lower end of the lower chord member 2 and the lower end of a diagonal member 4 connected thereto are removed and the lower end of a new lower chord and a new diagonal member are attached. Thus, the lower end of the lower chord member 2 and the lower end of the diagonal member 4 can be removed while maintaining the truss shape with the temporary truss. Therefore it is possible to replace members with minimum equipment while maintaining the self-standing property of a bridge having a truss structure.SELECTED DRAWING: Figure 3
【課題】トラス構造物の自立性を保持しながら最小限の設備で部材を取り替えることのできるトラス構造物の部材取替方法を提供する。【解決手段】上弦材１と下弦材２との間に仮弦材７を取り付けるとともに、仮弦材７と上弦材１とを複数の仮斜材８で連結して仮トラスを形成し、下弦材２及びこれに連結する斜材４の下端側を取り除いて新たな下弦材及び新たな斜材の下端側を取り付けるようにしたので、仮トラスによってトラス形状を保持したまま下弦材２及び斜材４の下端側を取り外すことができ、トラス構造物である橋体の自立性を保持しながら最小限の設備で部材を取り替えることができる。【選択図】図３
