In-situ reinforcing device and method for rusted steel bars
The invention provides an in-situ reinforcing device and method for rusted steel bars. The in-situ reinforcing device comprises a shaping mold which is formed by splicing two parts and is used for accommodating the rusted steel bars, an aluminothermy welding flux and a high-temperature match. The rusted steel bars are directly reinforced in situ on site, additional steel bars are not needed, the reinforcement ratio of the steel bars is guaranteed, and the problem that the original structural strength is affected by aging and rusting of the steel bars is solved. The problem that the strength of an original structure is affected by aging and rusting of the steel bars is solved, and iron oxide is reduced to the steel surface without rust through the aluminum replacement reaction.
本发明提供了一种锈蚀钢筋原位加固装置及方法，包括：两部分拼装的定型模具，用来内置锈蚀钢筋、铝热焊剂和高温火柴。本发明通过直接在现场原位将锈蚀钢筋加固的方式，不需要额外增加钢筋，保证钢筋的配筋率，解决钢筋老化锈蚀影响原结构强度的问题。本发明解决了钢筋老化锈蚀影响原结构强度的问题，通过铝置换反应将铁的氧化物还原没有铁锈的钢材表面。
