The steel material has the advantages of high strength, light dead weight, good integral rigidity, strong deformation resistance and the like, so the steel material is widely applied to the building industry. However, the fire endurance of steel without the sprayed refractory is only 15 minutes, and when a fire occurs, the steel is quickly deformed and failed due to the rapid reduction of the yield strength of the material, and personnel in a building do not have enough escape time and rescue time, so that the steel must be protected against fire when used in a high-rise building.

At present, a fireproof isolation layer is often sprayed on the surface of a steel column to improve the fireproof performance of the steel column, and the fireproof isolation layer is mainly divided into a thin-coating type steel structure fireproof coating, a thick-coating type steel structure fireproof coating and an ultra-thin type steel structure fireproof coating, wherein the thick-coating type steel structure fireproof coating is a coating with the thickness of 8-45 mm, and the fireproof limit of the fireproof coating can reach two hours. In fire, the temperature rise of steel is delayed and the steel is protected by means of the incombustibility, low thermal conductivity or heat absorption of the material in the coating.

The internal and external corners on the building comprise internal corners of the wall and external corners of the wall, wherein the internal corners of the wall refer to the recessed corners, the external corners of the wall refer to the protruded corners, in the building construction process, the processing of the internal corners and the external corners is always a difficult point, and after the construction is finished, the internal corners and the external corners are often measured by adopting an internal corner ruler, so that whether the construction of the internal corners and the external corners is qualified or not is judged.
