Steel fiber common template frame and preparation method thereof

Abstract

The invention discloses a steel fiber common type template frame and a preparation method thereof. The steel fiber common type template frame comprises a template, reinforcing steel bars and opposite-pull connecting pieces, and the template comprises the following materials: cement, natural sand, steel fibers, silica fume, fly ash, polycarboxylate superplasticizer powder, an antifoaming agent, rubber powder and an early strength agent. The template frame has the beneficial effects that: the thickness of the template frame is 20 mm, the template frame 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 the breaking strength of the template material can be improved to a large extent by arranging the steel fibers, and meanwhile brittle failure of the template material can be avoided.The produced template material is high in fluidity, can be self-leveled, does not need to be vibrated during template forming, uses ordinary Portland cement, is lower in cost, adapts to the requirements of building industrialization in the aspects of saving field labor, saving turnover materials and the like, and can greatly improve the production efficiency of components.

Description

technical field [0001] The invention relates to a support-free permanent formwork, in particular to a steel fiber ordinary formwork frame and a preparation method thereof, belonging to the technical field of building materials. Background technique [0002] Permanent formwork refers to some prefabricated panels that act as formwork during construction and are one of the components of the structure itself after pouring concrete. Nowadays, special-shaped (corrugated, ribbed, etc.) metal sheets (also known as profiled steel plates), prestressed concrete sheets, glass fiber cement formwork, small beam filler blocks, steel truss concrete panels, etc. are commonly used at home and abroad. [0003] The support-free permanent formwork has been used in some high-rise buildings in our country. After laying, it is slightly supported, and then the reinforced concrete is laid on it to form the floor slab, which is easy to construct. [0004] For the formwork materials currently on the m...

AI Technical Summary

Problems solved by technology

[0004] For the formwork materials currently on the market, firstly, the formwork material is thicker and occupies a large building area; secondly, the distance between the two-way connectors is small, resulting in many connectors and high cost; thirdly, the formwork contains glass fiber mesh grid cloth or steel wire mesh, resulting in a longer time for formwork removal, based on this, the application proposes a steel fiber ordinary formwork frame and its preparation method
