REINFORCEMENT CONSTRUCTION METHOD AND REINFORCEMENT STRUCTURE
PROBLEM TO BE SOLVED: To provide a reinforcement construction method and a reinforcement structure with simple and little work burden of construction, suppressing the extension of cracks etc. happened in steel members of a steel structure, and restoring the strength degradation by the section decrease occurred by cracks and corrosion.SOLUTION: The reinforcement construction method for reinforcing a partially damaged steel structure 8, comprises: a removing process of removing a surface treatment 4 from a steel member 2 used for the steel structure 8; and a coating process of applying a fiber reinforced paste 5 to a surface 20 of the steel member 2. In the removing process, the steel member 2 is exposed by removing the plating or painting provided as the surface treatment 4 of the steel member 2 around a defect portion 3 where the steel member 2 is partially damaged. In the coating process, the fiber reinforced paste 5 is applied so as to cover the defect portion 3 in an exposure range R1 where the surface treatment 4 is removed and the steel member 2 is exposed.SELECTED DRAWING: Figure 5
【課題】鋼構造物の鋼材に発生したき裂等の進展を抑制し、き裂、腐食等で生じた断面減少による強度低下を回復するものとして、簡便で施工時の作業負担の少ない補強工法及び補強構造を提供する。【解決手段】本発明を適用した補強工法は、部分的に欠損した鋼構造物８を補強するためのものであり、鋼構造物８に用いられた鋼材２から表面処理４を除去する除去工程と、鋼材２の表面２０に繊維強化ペースト５を塗布する塗布工程とを備える。除去工程では、鋼材２が部分的に欠損した欠損部３の周囲で、鋼材２の表面処理４として設けられためっき又は塗装を除去することで鋼材２を露出させる。塗布工程では、表面処理４を除去して鋼材２を露出させた露出範囲Ｒ１で、欠損部３を覆うように繊維強化ペースト５を塗布することを特徴とする。【選択図】図５
