Steel fiber quick-hardening template frame and preparation method thereof

Abstract

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.

Description

technical field [0001] The invention relates to a support-free permanent formwork, in particular to a steel fiber rapid-hardening formwork frame and a preparation method thereof, belonging to the technical field of building materials. Background technique [0002] Permanent formwork means that when making reinforced concrete structural members, the forming formwork used is one-time. After the concrete is formed, the formwork and concrete become one. [0003] As a kind of permanent formwork, rapid-hardening formwork needs to be able to be rapidly formed to meet special construction requirements. For the rapid-hardening formwork currently on the market, first, the thickness of the formwork material is relatively thick, and it occupies a large building area. 1. The distance between the connecting parts is small, resulting in many connecting parts and high cost. Thirdly, the formwork contains glass fiber mesh cloth or steel wire mesh, which leads to a long time for formwork remo...
