Steel structure building outer wall I-shaped steel beam coating structure

The invention relates to the technical field of steel structure building outer wall enclosure systems, in particular to a steel structure building outer wall I-shaped steel beam coating structure which comprises a metal panel located on the outer side of an I-shaped steel beam, a steel keel component connected to the inner side of the metal panel and a fireproof heat preservation structure installed on the I-shaped steel beam. The two ends of the metal panel abut against an external heat preservation decoration structure arranged on the outer side of the wall, the I-shaped steel beam is connected with the steel keel component through a first connecting assembly, and the metal panel is connected with the steel keel component through a second connecting assembly. The construction technology is simple and rapid, the number of wet operation steps is small, construction quality is easier to guarantee, the connecting strength between the I-shaped steel beam and the external envelope system is improved, construction
