Aluminum alloy formwork is an important technology for energy conservation and emission reduction in the construction industry, which can improve the construction efficiency and quality of housing construction. It has been widely promoted and applied in current construction projects.

　　Compared with steel formwork, aluminum alloy formwork has greater strength, is not afraid of water, and does not rust. At the same time, compared to bulky steel, aluminum alloy has a much lighter weight, which is conducive to the construction of construction projects. It is also particularly suitable for areas lacking labor sources and high labor costs.

Overview of aluminum alloy templates

　　The aluminum alloy template adopts a new type of template and support system with high efficiency, modularization, and high reusability, as well as a corresponding new construction method that effectively saves construction site labor costs. Try to handle and complete as many problems that have traditionally occurred on construction sites and many tasks that have been handled on site as possible in the factory. This is the concept of building construction industrialization.

　　Before construction, professional personnel will use computer-aided design to standardize, modularize, and systematize all templates required for the building project. Apply the latest technology in the fields of materials and building structures, integrating wall formwork, top formwork, and support systems. The support system adopts a new design concept of early dismantling system, which is perfectly integrated with the top mold to improve template turnover rate and reduce template usage.

　　Using the template system working diagram designed from this as a guide, a list of templates and accessories required for the project is listed. Production is completed in the factory through strict quality management system and process control, and each template and accessory is coded. Before transportation to the construction site, a 100% overall trial assembly will be carried out in the factory based on the construction site situation, and any possible errors and omissions will be resolved outside the construction site.

　　This effectively ensures the construction quality and efficiency on site. With a little training, manual workers can complete on-site construction quickly, efficiently, and safely through simple assembly operations according to the drawings.

　　Although the country is currently vigorously promoting it, there are still many people who have doubts about the practical application of aluminum alloy templates. The editor will discuss these questions with everyone:

　　Question 1: How much weight can aluminum alloy templates reduce?

　　Made of high-strength aluminum alloy, with an average weight of 25 kilograms per square meter. A large template of approximately 2.5 square meters can be easily carried by one person.

　　Question 2: Aluminum is lighter, is it unsafe?

　　The construction of aluminum formwork can reduce the external load on it. Due to the large contact surface of the aluminum formwork itself, it can greatly reduce some pressure effects, and then differentiate into external loads, making the construction process safer.

　　Question 3: How to control the cost of replacing traditional templates with aluminum templates?

　　Good design is the key to reducing the flexible cost of aluminum templates, and because design is the primary link in the production process of aluminum templates, a precise and high-quality design can smoothly guide production, assembly, and construction. The integrated, standardized, and modular system design can facilitate the implementation of one-time pouring, making on-site operations simple and feasible, and greatly saving on-site labor and labor costs. Effectively shorten the construction period, usually completing the assembly and pouring of one floor every 3-4 days, saving labor costs.

　　Question 4: What are the advantages of aluminum templates?

　　1. Long service life, with an average lifespan of 300 to 500 cycles or more for aluminum alloy templates.

　　2. All structures are assembled using aluminum alloy templates, and after assembly, they form an overall framework with good stability and high bearing capacity.

　　3. The top mold and support system have achieved integrated design, integrating early dismantling technology into the top plate support system, greatly improving the turnover rate of the template.

　　4. The aluminum template support rods are relatively few, with large on-site operation space, smooth personnel flow, and convenient material handling, greatly improving on-site management efficiency.

　　5. After the removal of the aluminum alloy formwork system, the surface quality of the concrete is flat and smooth, achieving the effect of finishing with plain concrete.

　　6. Wide application range, suitable for housing construction, infrastructure, water channels and tunnels, etc.

　　Question 5: What projects are suitable for aluminum templates?

　　Generally speaking, projects that meet the following 5 requirements are very suitable for using aluminum templates

　　1. Floor height

　　Priority should be given to selecting aluminum alloy templates with a layer height of 2.8-3.2 meters, and if the layer height exceeds 3.2 meters, traditional support methods such as horizontal bars and diagonal braces should be used.

　　2. Outer frame

　　The combination of aluminum formwork and external climbing frame is a good construction method. If the outer frame is a cantilever frame, special treatment is required during template design, manufacturing, and on-site installation, resulting in high cost and increased construction difficulty.

　　3. Structural form

　　The shear wall structure and frame shear structure are the best, while other structures have more masonry walls, and the advantage of using aluminum molds is not obvious.

　　4. External structure

　　There are not many exterior lines and the changes are not complex.

　　5. Comprehensive economy

　　A single building is used for about 30 times, which is the first time it is used in a building with more than 30 floors. Multiple buildings of the same type have been used more than 30 times in total.
