The invention relates to the technical field of building steel structure fire prevention, in particular to a lightweight concrete fireproof construction method for a building steel structure. The fireproof construction method comprises the following steps that scaffolds are erected, specifically, the scaffolds are erected around a to-be-constructed steel member; smearing glue: smearing a layer of glue on the surface of the steel member, and air-drying; net hanging construction is conducted, specifically, reinforcing meshes are hung on the surfaces of the steel members through connecting pieces; spraying lightweight concrete: spraying the stirred lightweight concrete to the surface of the steel member, and enabling the sprayed lightweight concrete to submerge the reinforcing mesh in the step 3; curing the lightweight concrete; paint spraying: spraying a layer of paint on the surface of the lightweight concrete; and dismantling the scaffold. The lightweight concrete fireproof material is low in cost, the cost i
