The invention discloses a reinforced concrete self-curing device for winter construction in a cold region and a curing method thereof. In winter construction in a cold region, existing reinforced concrete curing measures are large in energy consumption, high in economic cost and difficult to match with reinforced concrete curing in the cold region, and due to the fact that the concrete curing temperature fluctuates and is difficult to stabilize under the condition of long-time negative temperature, curing quality is difficult to unify. According to the device provided in the invention, a heat preservation layer is arranged on the outer wall of a formwork frame body, a reinforcement cage is arranged in the formwork frame body, the formwork frame body is filled with conductive concrete, when the reinforcement cage is in a power-on state, the reinforcement cage and the conductive concrete form a conductive reinforced concrete structure body, and the conductive reinforced concrete structure body achieves the self-curing process through the voltage difference. According to the curing method, finite element software is adopted to establish a quantitative relation between the electrifying power and the curing temperature of the conductive reinforced concrete structure body, the curing power in the curing process is controlled in real time through the quantitative relation, so that the whole heating curing process of the conductive reinforced concrete structure body is realized.
用于寒区冬季施工的钢筋混凝土自养护装置及其养护方法。在寒区冬季施工中，现行钢筋混凝土养护措施耗能量消耗大，经济成本高，难以匹配寒区钢筋混凝土养护，因长时间负温情况下混凝土养护温度出现波动，难以稳定，导致养护质量难以统一。本发明中模板框体的外壁上设有保温层，模板框体内设有钢筋笼，模板框体内填充有导电混凝土，当钢筋笼处于通电状态时，钢筋笼和导电混凝土形成导电钢筋混凝土结构体，导电钢筋混凝土结构体通过电压差实现对自身养护过程；养护方法为采用有限元软件建立导电钢筋混凝土结构体通电功率与养护温度间的量化关系，通过该量化关系对养护过程中养护功率的实时控制，实现对导电钢筋混凝土结构体全程加热养护过程。
