Steel fiber quick-hardening template frame and preparation method thereof
The invention discloses a steel fiber quick-hardening template frame and a preparation method thereof. The steel fiber quick-hardening template frame comprises a template, reinforcing steel bars and opposite-pull connecting pieces, and template materials comprise cement, natural sand, steel fibers, silica fume, a retarder, polycarboxylate superplasticizer powder, a defoaming agent, rubber powder and an accelerator. The frame has the beneficial effects that the thickness of the formwork is 20 mm, the formwork has higher strength, the distance between the opposite-pull connecting pieces can be set to be 40 cm, the number of the connecting pieces can be reduced to a large extent, the cost of the opposite-pull connecting pieces is reduced, the compressive strength and breaking strength of formwork materials can be improved to a large extent by arranging the steel fibers, and meanwhile brittle failure of the formwork materials can be avoided. The produced template material is high in fluidity and can be self-leveled, vibration is not needed during template forming, the requirements of building industrialization are met in the aspects of saving on-site labor, saving turnover materials and the like, and the production efficiency of components can be greatly improved.
本发明公开了一种钢纤维快硬型模板框架及其制备方法，包括模板、钢筋、对拉连接件，模板材料包括水泥、天然砂、钢纤维、硅灰、缓凝剂、聚羧酸减水剂粉剂、消泡剂、胶粉、速凝剂。本发明的有益效果是：该模板厚度为20mm，具有更高的强度，可以使对拉连接件间距设置为40cm，能够很大程度上降低连接件的数量，降低对拉连接件成本，设置钢纤维能够较大程度的提高模板材料的抗压、抗折强度，同时也可避免模板材料脆性破坏。所生产的模板材料流动度大，可自流平，模板成型时无需振捣，在节省现场人工、节省周转料等方面适应了建筑工业化的需求，能极大提高构件生产效率。
