What Is Aluminum Formwork?
The aluminum formwork is called an aluminum formwork for construction. It is a new generation of formwork system after wood formwork and steel formwork. The aluminum template is designed according to the modulus, extruded by special equipment, and can be freely combined according to different structural sizes. The design, development and application of aluminum formwork is a major development in the construction industry. The application of the aluminum formwork system in the construction industry has improved the construction efficiency of housing construction projects, including construction materials and manual arrangements, which have greatly saved a lot.
Aluminum formwork
- Aluminum formwork is a building template made of aluminum alloy, also known as
- Since its birth in the United States in 1962, aluminum formwork has a history of 55 years. It has been widely used in buildings in developed countries such as the United States, Canada, and emerging industrial countries such as Mexico, Brazil, Malaysia, South Korea, and India.
- The largest application builder of aluminum formwork is Vanke, one of the leaders in the real estate industry. Almost all high-rise buildings of Vanke have specified the use of aluminum formwork systems. When the Vanke Dream Factory was built, an aluminum formwork system was used. This symbolizes a big progress in our country in the construction industry.
- The Dongguan Vanke Songhu Legend Garden project is also a green construction system. In addition to green building materials, an aluminum formwork system is also used. This project held a study tour as a green construction demonstration unit. application.
Green construction building
- The components of the aluminum formwork system need to be designed in accordance with the characteristics of the floor, and the ability of design technicians is high. About 80% of the modules in the aluminum formwork system can be recycled in multiple projects, while the remaining 20% can only be recycled in a class of standard floors. Therefore, the aluminum formwork system is suitable for super-high-rise buildings or multi-storey buildings with a high degree of standardization And villa complex. The following technical advantages are particularly reflected in regions with a high degree of urbanization:
1) Short construction period. The aluminum formwork system is a quick-release formwork system. The normal construction of a set of formwork can reach one level in four days, and the pipeline construction can be better carried out, which greatly improves the construction progress and saves management costs.
2) There are many times of repeated use, and the average use cost is low. The aluminum formwork system uses the aluminum alloy profile formed by the overall extrusion as the raw material, and a set of formwork can be used over 300 times for standard construction. The purchase price of a set of templates is amortized, which saves a lot of cost than traditional templates.
3) Convenient construction and high efficiency. The aluminum formwork system is simple and convenient to assemble, with an average weight of about 20kg. It is completely handled and assembled by hand without the assistance of any mechanical equipment. Moreover, the system design is simple, and the workers can get up to speed quickly. Skilled installers can install 20-30 square meters per person per day, greatly saving labor costs.
4) Good stability and high bearing capacity. The bearing capacity of most aluminum formwork systems can reach 60KN per square meter, which is sufficient to meet the supporting capacity requirements of most residential building groups.
5) Wide application range. Aluminum formwork is suitable for the use of walls, horizontal floors, columns, beams, stairs, windowsills, flaps and other positions. It is also useful for secondary structural support such as ring beams, structural columns, and anti-bumps.
6) Less joints, high precision, good concrete surface effect after demoulding. After demolishing the aluminum building formwork, the surface quality of the concrete is smooth and smooth, which can basically meet the requirements of facing and clear concrete, without the need for batching, which can save the batching costs.
7) The construction site has less waste and the supporting system is simple. All the accessories of the aluminum formwork system can be reused. After the construction is demolished, there is no garbage on the site. The support system has a simple structure and is easy to remove, so the entire construction environment is safe, clean and tidy.
8) Standard and universal. There are many specifications of aluminum formwork, which can be assembled with different specifications according to the project. When the used formwork is used to rebuild a new building, only about 20 non-standard boards need to be replaced, which can reduce costs.
9) High recycling value. After the aluminum formwork is discarded, when the residual value of the waste treatment is high, the cost sharing advantage is obvious.
10) Low carbon emission reduction. All materials of the aluminum formwork system are renewable materials, which meet the national regulations on energy conservation, environmental protection, low carbon and emission reduction of construction projects.
- Many formwork accessories are relatively easy to make it difficult to install and classify; noise during the installation process; high thermal conductivity; poor elasticity of the molding pad; more seams than large formwork; swaying;
- Aluminum formwork construction is popular, mainly because the technical indicators are more advanced and can better meet the national and social requirements for construction projects.
- The whole process of construction preparation of aluminum formwork system is as follows:
- The design of architectural drawings and structural drawings is completed the drawings are reviewed and quoted by the aluminum formwork technicians the content of the cooperation is negotiated, and the contract is signed the technical personnel design the model drawing (template assembly drawing) production according to the drawing factory preassembly qualified inspection delivery , Delivery site construction.
- Construction process of aluminum formwork:
- Wall formwork beam formwork staircase formwork formwork acceptance concrete pouring quality acceptance mold removal (first installation and then demolition) transport to the previous layer for construction.
