TRUSS BRIDGE MEMBER REPLACEMENT METHOD AND REBUILDING METHOD
To provide a member replacement method and a rebuilding method for a truss structure capable of replacing a member or rebuilding with minimum equipment while maintaining the independence of a bridge body as being a truss structure.SOLUTION: A temporary truss is formed by installing a temporary chord material 7 between an upper chord material 1 and a lower chord material 2, while connecting the temporary chord member 7 and the upper chord member 1 with a plurality of temporary diagonal members 8, so that the lower chord member 2 and the lower end sides of diagonal members 4 connected thereto are removed to attach a new lower chord member and the lower end sides of new diagonal members. Therefore, the lower chord member 2 and the lower end sides of the diagonal members 4 can be removed while maintaining the truss shape with the temporary truss, and the members can be replaced with minimal equipment while maintaining the independence of the bridge body as being a truss structure.SELECTED DRAWING: Figure 3
【課題】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の取り替えまたは架け替えを行うことのできるトラス構造物の部材取替方法及び架替方法を提供する。【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
