摘要

[Solution];A reinforcement device to reinforce a boiler tube having a weld portion includes : a strip- shaped first steel plate configured to be wound and fixed by welding in a region including the weld portion; a first reinforcement member having a shape to make surface contact with an outer peripheral surface corresponding to one semi-circumference of the boiler tube in an outer peripheral surface of the first steel plate wound around the boiler tube; a second reinforcement member having a shape to make surface contact with an outer peripheral surface corresponding to another semi-circumference of the boiler tube in the outer peripheral surface of the first steel plate, the second reinforcement member configured to cover the outer peripheral surface of the first steel plate together with the first reinforcement member; and a coupling member configured to couple the first and second reinforcement members together around the boiler tube.
