Common support-free permanent formwork frame and preparation method thereof
The invention discloses a common support-free permanent formwork frame and a preparation method thereof. The common support-free permanent formwork frame comprises formworks, opposite-pull connectingpieces and reinforcing steel bars. The formwork materials comprise common Portland cement, natural sand, silica fume, fly ash, a water reducing agent, a defoaming agent, rubber powder and an early strength agent. The common support-free permanent formwork frame has the beneficial effects that the permanent formwork is thinner and higher in strength, the distance between the opposite-pull connecting pieces can be larger, the number of the connecting pieces can be reduced to a large extent, and the cost of the opposite-pull connecting pieces is reduced; the early strength is higher, that is, theformworks can be removed within 24 hours, and the production efficiency is improved to a large extent; the fluidity is high, self-leveling can be achieved, and vibration is not needed during templateforming; and the ordinary Portland cement is used, so that the cost is lower.
本发明公开了一种普通免支撑永久模板框架及其制备方法，包括模板、对拉连接件、钢筋，模板材料包括普通硅酸盐水泥、天然砂、硅灰、粉煤灰、减水剂、消泡剂、胶粉以及早强剂。本发明的有益效果是：该永久模板更薄，具有更高的强度，可以使对拉连接件间距更大，能够很大程度上降低连接件的数量，降低对拉连接件成本。更高的早期强度，即24小时拆模，较大程度上提高生产效率。流动度大，可自流平，模板成型时无需振捣。使用普通硅酸盐水泥，成本更低。
