    • PURPOSE:To enhance fire resisting performance by applying fire resisting paint to the internal surface of U-shape section which consists of a web and a flange of a steel column made of wide flange beam, mounting a fire resisting outer side plate to the outside and spraying a fire resisting material into the steel column. CONSTITUTION:A web 2a of a steel column 2 made of wide flange beam is used so that it may run in parallel to the outside of a building. Fire resisting paint 3 is applied to the internal surface of a U-shaped section formed with the web 2a and flanges 2b on both sides. Then, after the steel column 2 has been erected, a tieback material 4 is mounted with a small machine screw and a fire resisting adhesive agent between a fire resisting outer side plate 1 and the flanges 2b of the steel column 2 so that the fire resisting outer side plate 1 may be fixed. Then, after metal laths 5 have been applied to the outside of the tieback material 4, a fire resisting material 6 is sprayed to the steel column 2 from the inside of a building. A curtain wall 7 is mounted to the outside of the fire resisting outer side plate 1.
