After assembling the steel frame, a refractory material mixed with rock wool, cement slurry or the like is sprayed on the steel frame. At that time, for example, when a refractory material is sprayed on the bottom surface of the bottom wall of the steel frame facing the ground side, such as the bottom surface part of the beam, when the steel frame part is sprayed, the rust peels off from the steel frame due to the weight of the sprayed refractory material The refractory material comes off the steel frame along with the rust. Therefore, when the refractory material is sprayed on the bottom surface of the bottom wall of the steel frame, an operator has scraped off the rust in advance using a tool such as a scraper or a wire brush below the steel frame surface portion.

効率よく行えるサビ落とし装置を提供することにある。However, in scraping off rust with a tool such as a scraper or a wire brush, it is necessary to bring the scraper and the wire brush into contact with the entire lower surface of the bottom wall of the steel frame. There was a very bad defect. Also, when a worker scrapes off rust with a tool such as a scraper or a wire brush below the steel frame, the scraped rust scatters and hits the worker, which adversely affects the working environment and adversely affects the human body. was there. In addition, in order to scrape off rust from steel beams at relatively high places such as beams, workers must ride on a stepladder, ladder, or a self-propelled simple elevator to perform scraping work in an unstable posture. Since it does not happen, there was a problem with danger. The present invention has been made in view of the above circumstances, and an object of the present invention is to scrape off rust from the steel surface of a structure having a steel structure, which can improve the work environment and the steel frame is located at a high place. Even so, it is to provide a rust removing device that can safely and efficiently perform a rust removing operation.

However, the present invention is, for example, a steel frame made of I-shaped steel or a cross section having an approximately inverted T-shape. Needless to say, it can be widely applied when scraping off the rust adhering to the lower surface of the bottom wall of the steel frame made of shaped steel. Further, in this embodiment, the case where the rust adhering to the lower surface 701 of the lower flange 7 of the H-shaped steel 1 extending in the horizontal direction is scraped off is described, but the steel frame extending in the vertical direction or the diagonal extension Of course, it can be applied to the case where the rust is scraped off by adhering to the steel surface of the installed steel frame.
