With the construction industry moving towards green and environmental protection, it will be the development trend of the mold base industry in China to provide mold base products with 'low emission, low loss, automation and lightweight' for green construction. as Plastic mold Plate aluminium alloy The formwork has won the recognition and high evaluation of the market due to its advantages of portability, durability, environmental protection and high efficiency. Jianda hollow plastic construction formwork, a new type of plastic construction formwork produced by the industry using imported polypropylene resin as the base material, has been chemically restructured, melted and extruded, and has excellent performance. It uses plastic instead of wood, tasteless, harmless, and pure. It does not produce any toxic and harmful substances in the use process. The new hollow plastic construction formwork is widely used, which saves both resources and costs, And the construction quality is improved.
"In China, the cost of formwork engineering accounts for 25% - 35% of the total cost of cast-in-place concrete structure engineering, and 50% - 60% of the total construction period. The cost accounts for about 5% of the total engineering cost." Gao Feng, secretary-general of China Formwork and Scaffolding Association, said, "It is expected that the total output of formwork related industries will reach 1 trillion yuan in the future." It can be seen that, Formwork related industries account for a large proportion of output value in both developed countries and China's construction industry. Since entering the new century, with the upgrading of new construction technology, rate and high quality demand in the construction industry, coupled with the national requirements for environmental protection and the increasing labor costs, the development and application of new construction templates has become an important way to promote the technological innovation of template engineering, reduce project costs, and help the modernization of the construction industry. Plastic building formwork is the fourth generation of new environment-friendly building materials after wood formwork, bamboo formwork and steel formwork, which has been strongly supported and encouraged by the Ministry of Housing and Urban Rural Development of the People's Republic of China. According to relevant statistical data, 11 tons of standard coal can be saved for every ton of plastic building formwork used in production, which is of great significance to energy conservation and emission reduction.
The new hollow plastic construction formwork of Fangyuantong is a typical demonstration of "replacing wood with plastic". Compared with traditional steel formwork, wood formwork, aluminum alloy formwork and plastic solid formwork, it has the advantages of environmental protection, corrosion resistance, reusability, etc. Its use cost is only a fraction of that of wood formwork, while retaining the original wood formwork that can be nailed, sawed, drilled, cut and has strong nail holding force Lignocellulose It is characterized by improving construction difficulty, light construction, labor and time saving, and is widely applicable to high-rise buildings and bridge construction; High strength, impact resistance, abrasion resistance, long service life, high turnover rate, more than 50 times of turnover, light weight, long service life.
The surface of Fangyuantong new hollow plastic building formwork is made of polymer material, which is smooth and clean, without the need to apply release agent, reducing cleaning and maintenance costs. The surface of the poured objects is smooth and beautiful. After concrete pouring, it can meet the requirements of the clean wall. By subtracting the secondary plastering process of the wall, it can directly stick to the surface, reduce the construction period by 30%, and effectively save construction costs, The square and round hollow plastic building formwork greatly improves the turnover times, solves the secondary pollution problem of wood formwork, meets the national requirements for energy conservation and environmental protection, and is also the direction of national industrial policy development. With superior performance and higher comprehensive economic benefits, it is widely used in families, shopping malls, office buildings, libraries, exhibition halls, stations, factory buildings, warehouses, underground garages Civil air defense projects and other types of construction projects.
In a word, the square, round and hollow plastic construction formwork has the common use characteristics of conventional construction formwork and more characteristics than conventional formwork. The square and round hollow plastic building formwork will certainly become the ideal building formwork product in the 21st century in which plastic is used to replace wood, plastic is used to replace steel, and plastic is used to replace bamboo. It is an engineering formwork board A complete revolution in materials.
