Lightweight concrete fireproof construction method for building steel structure
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 input is reduced, the construction method is simple, air environment pollution and fire hazards are avoided, and construction is safe; the lightweight concrete cementing agent or the fireproof glue can increase the adhesiveness of the lightweight concrete and the steel structure and prevent falling off; the hanging net is laid, so that the firmness of the concrete is improved.
本发明涉及建筑钢结构防火技术领域，具体为一种用于建筑钢结构的轻质混凝土防火施工的方法。该防火施工的方法，包括以下步骤：搭设脚手架：在待施工的钢构件周围搭设脚手架；抹胶：在钢构件表面涂抹一层黏胶，并风干；挂网施工：将钢筋网片通过连接件挂在钢构件表面；喷涂轻质混凝土：将搅拌好的轻质混凝土喷涂到钢构件表面，使喷涂的轻质混凝土没过步骤三中的钢筋网片；固化轻质混凝土；喷涂油漆：在轻质混凝土表面喷一层油漆；拆除脚手架。轻质混凝土防火材料成本低，减少了成本投入，施工方法简单，无空气环境污染、火灾隐患，施工安全；轻质混凝土胶结剂或防火胶可增加轻质混凝土和钢结构粘着性，防止脱落；铺设挂网，增加混凝土的牢固性。
