EXTENSION STRUCTURE ADDED ON STEEL STRUCTURE USING STRUCTURE MEMBER AND EXTENSION METHOD
PROBLEM TO BE SOLVED: To provide a structure and method, which can easily and definitely add necessary structure member at construction site on an existing steel structure that requires application change or has partial loss of cross section due to corrosion without bolt connection or welding connection.SOLUTION: In an extension structure added on a steel structure using a structure member, the steel structure and the structure member that is added on the steel structure are connected through a joint layer that is formed by impregnating a strengthened fiber base material with resin and hardening the resin. An extension method can add the structure member on the steel structure at construction site.SELECTED DRAWING: Figure 5
【課題】用途変更を必要とする既設の鋼構造物や腐食等により断面欠損した既設の鋼構造物に対して、ボルト接合や溶接接合を実施せずに、施工現場でも容易にかつ確実に必要な構造用部材を増設可能な構造および方法を提供する。【解決手段】鋼構造物と該鋼構造物に増設される構造用部材とが、強化繊維基材に樹脂が含浸、硬化されて形成された接合層を介して接合されていることを特徴とする、鋼構造物への構造用部材による増設構造、およびその構造用部材の増設を施工現場で実施可能な増設方法。【選択図】図５
