Construction method for wrapping fireproof concrete outside steel pipe column
The invention discloses a construction method for wrapping a fireproof concrete outside a steel pipe column. The construction method comprises the steps that a reinforcing mesh is laid on the periphery of the steel pipe column, and the reinforcing mesh comprises annular reinforcing steel bars and vertical reinforcing steel bars; cushion blocks are installed, the inner walls of the cushion blocks make contact with the outer wall of the steel pipe column, and the annular reinforcing steel bars and vertical reinforcing steel bars of the reinforcing mesh are correspondingly connected into transverse openings and vertical openings of the cushion blocks; a formwork is erected on the periphery of the reinforcing mesh, and the inner wall of the formwork abuts against the outer walls of the cushion blocks; and concrete is poured between the formwork and the steel pipe column. According to the technical scheme of the construction method for wrapping the fireproof concrete outside the steel pipe column, it can be guaranteed that the distance between the formwork and the steel pipe column is equal through the cushion blocks, it is guaranteed that the thickness of a protection layer is uniform, and the concrete pouring quality is high; the pouring time is shortened, the concrete shelving time is shortened, and the quality of wrapping the concrete outside the steel pipe column is guaranteed; and the single-layer reinforcing mesh is adopted, so that a vibrating rod can conveniently penetrate into the interior for vibrating.
本申请公开了一种钢管柱外包防火混凝土的施工方法，包括在钢管柱的外周铺设钢筋网，所述钢筋网包括环形钢筋和竖钢筋；安装垫块，垫块的内壁与钢管柱的外壁接触，钢筋网的环形钢筋和竖钢筋分别连接于垫块的横开口和竖开口内；在钢筋网的外周支设模板，所述模板的内壁顶于所述垫块的外壁上；在所述模板和钢管柱之间浇筑混凝土。应用本申请实施例所提供的技术方案，通过垫块可以保证模板距离钢管柱的距离相等，保证保护层厚度均匀，混凝土浇筑质量较高；浇筑时间缩短，减少混凝土搁置时间，保证了钢管柱外包混凝土质量；采用单层钢筋网，方便振动棒深入内部振捣。
