What is the general material used for the mold frame?

With the rapid development of the construction industry, the selection and use of mold materials has become a topic of increasing concern in the industry. Mold frame is an indispensable temporary support structure in building construction, which is mainly used for concrete pouring. Choosing the right material can not only ensure the safe and smooth construction, but also reduce the cost of the project and improve the quality of the project. So, what is the general use of mold materials? This article will start from different types of mold materials for you to analyze in detail.

1. Steel

As a traditional mold material, steel has the advantages of high strength, high stiffness, wear resistance, convenient construction, etc., and is widely used in the construction of various types of concrete structures. Steel mold frame can be divided into Angle steel mold frame, groove steel mold frame, round steel mold frame, H-type steel mold frame, etc. Among them, Angle steel mold and groove steel mold are suitable for small and medium-sized projects, and round steel mold and H-type steel mold are suitable for large projects.

However, the steel mold frame also has some problems. First of all, steel prices are greatly affected by market fluctuations, which increases the uncertainty of project costs. Secondly, the recycling rate of steel is low, which is not conducive to resource conservation and environmental protection. Finally, the steel mold frame is easy to produce noise and sparks in the construction process, which has a certain impact on the safety and environment of the construction site.

Two, wood

Wood, as a natural molding material, has a long history in our country. Wood mold frame has the advantages of low cost, convenient processing, light weight, simple construction and so on. In the construction of small and medium-sized concrete structures, wood formwork is an ideal choice. Wood mold frame can be divided into wood fang mold frame, plywood mold frame, wood formwork, etc. Among them, the wooden square molding is suitable for large projects, and the plywood molding and wood formwork are suitable for small and medium-sized projects.

However, there are also some problems with wood molding. First of all, the strength and stiffness of the wood is relatively low, and it is easy to be deformed by moisture, which reduces the construction quality. Secondly, the wear resistance and weather resistance of wood are poor, and the service life is limited. Finally, due to the limited resources of wood, overuse can lead to deforestation and environmental damage.

Third, aluminum alloy

As a new type of mold material, aluminum alloy has been widely used in China in recent years. Aluminum alloy mold frame has the advantages of light weight, high strength, high stiffness, wear resistance, corrosion resistance, convenient construction and so on. Aluminum alloy mold frame can be divided into aluminum alloy Angle steel mold frame, aluminum alloy groove steel mold frame, aluminum alloy round steel mold frame. Among them, aluminum alloy corner steel mold frame and aluminum alloy groove steel mold frame are suitable for small and medium-sized projects, and aluminum alloy round steel mold frame is suitable for large projects.

However, there are also some problems with aluminum mold frames. First of all, the price of aluminum alloy is relatively high, which increases the engineering cost. Secondly, the processing of aluminum alloy is more difficult, and the production equipment and technical requirements are higher. Finally, the recycling rate of aluminum alloy mold frame is low, which is not conducive to resource conservation and environmental protection.

Fourth, composite materials

Composite material refers to the combination of two or more different materials with new properties of the material. In recent years, with the continuous development of composite technology, composite mold frame has gradually become a new mold frame material. The composite mold frame has the advantages of light weight, high strength, high stiffness, wear resistance, corrosion resistance, etc., which is suitable for various types of concrete structure construction.

Composite mold frame can be divided into glass steel mold frame, carbon fiber mold frame, aramid fiber mold frame, etc. Among them, the glass steel mold frame has the advantages of low cost, convenient processing, etc., which is suitable for small and medium-sized projects; Carbon fiber mold frame and aramid fiber mold frame have the advantages of high strength and high stiffness, which are suitable for large-scale engineering.

In summary, what is the general use of mold materials? In fact, the choice of mold materials should be considered according to the needs of specific projects, costs, construction conditions and other factors. In practical application, according to the characteristics and advantages and disadvantages of different types of mold materials, combined with the actual situation of the project, the most suitable mold materials can be selected, so as to ensure the safety and smooth construction and improve the quality of the project.
