NOVELTY - The utility model claims a track steel structure based on graphene anti-corrosion fireproof coating, comprising a main body; an anti-corrosion layer and a fixing block; the bottom end of the main body is fixedly connected with a fixing block; the outer part of the main body is provided with an anti-corrosion layer; and the surface of the anti-corrosion layer is provided with a fireproof layer; two sides of the top end of the main body are provided with a protective structure; one end of the main body is provided with a splicing structure; the second slot is set in the inner part of one end of the protective structure; the third slot is set in the other end of the rail baffle. The utility model is provided with a splicing structure; when the two rail steel structures are spliced, firstly placing the two rail steel structure together, and making the third clamping block and the third clamping groove and the second clamping block and the second clamping groove are completely overlapped; when completely clamped and then fixed by the fixing bolt in the through hole matched with the next step, so as to realize the track steel structure convenient for splicing.
