What are the technical parameters of aluminium column formwork?

Aluminium column formwork has become an increasingly popular choice in the construction industry due to its numerous advantages such as lightweight, high strength, and recyclability. As a leading supplier of aluminium column formwork, I am often asked about the technical parameters of our products. In this blog post, I will delve into the key technical parameters of aluminium column formwork to help you better understand its performance and suitability for your construction projects.

Material Composition

The primary material used in our aluminium column formwork is high - strength aluminium alloy. The most commonly used alloy is 6061 - T6. This alloy is composed of approximately 97.9% aluminium, 0.6% silicon, 1.0% magnesium, 0.28% copper, 0.2% chromium, and small amounts of other elements. The 6061 - T6 alloy offers an excellent combination of strength, corrosion resistance, and weldability. Its yield strength is typically around 276 MPa, and the ultimate tensile strength can reach up to 310 MPa. These strength properties ensure that the formwork can withstand the high pressures exerted by the wet concrete during the pouring process.

Dimensions and Sizes

One of the significant advantages of our aluminium column formwork is its flexibility in dimensions. We can customize the formwork according to the specific requirements of your project. The standard panel sizes range from 200mm x 200mm to 1200mm x 2400mm. The thickness of the formwork panels usually varies from 4mm to 6mm, depending on the height and load - bearing requirements of the columns. For taller columns or columns with higher concrete pressures, we recommend using thicker panels to ensure stability.

In addition to the panel dimensions, the connectors and accessories also play a crucial role in determining the overall size and shape of the column formwork. Our formwork system uses a variety of connectors, such as pins, wedges, and bolts, which allow for easy assembly and disassembly. The connection points are designed to be precise, ensuring a tight fit between the panels and minimizing the risk of concrete leakage.

Surface Finish

The surface finish of the aluminium column formwork is an important factor that affects the quality of the concrete surface. Our formwork is treated with a special anti - adhesion coating, which not only makes it easy to remove the formwork after the concrete has set but also gives the concrete surface a smooth and uniform finish. The coating also protects the aluminium surface from corrosion, extending the service life of the formwork.

The smooth surface finish of the formwork reduces the need for additional surface treatment of the concrete, such as plastering, which can save both time and cost in the construction process. Moreover, the anti - adhesion coating is environmentally friendly, complying with all relevant environmental regulations.

Load - Bearing Capacity

The load - bearing capacity of the aluminium column formwork is determined by several factors, including the material strength, panel thickness, and the design of the support system. Our formwork is designed to withstand the lateral pressure exerted by the wet concrete during pouring. The maximum lateral pressure of fresh concrete depends on factors such as the concrete density, pouring rate, and temperature.

For normal concrete pouring conditions, our formwork can withstand a lateral pressure of up to 60 kN/m². However, for special projects with higher concrete pressures, we can provide reinforced formwork or additional support systems to ensure the safety and stability of the formwork. The support systems include Aluminum Formwork Support Connection Strips, which are used to connect the formwork panels and transfer the loads to the ground or other support structures.

Assembly and Disassembly

Ease of assembly and disassembly is a key advantage of our aluminium column formwork. The formwork system is designed to be modular, which means that the panels can be quickly assembled on - site using simple tools. The connectors are easy to install and remove, reducing the labor time and cost.

On average, a team of two to three workers can assemble a set of column formwork within a few hours, depending on the size and complexity of the columns. The disassembly process is even faster, as the anti - adhesion coating allows the formwork to be easily separated from the concrete surface. This rapid assembly and disassembly feature not only speeds up the construction process but also reduces the overall construction time and cost.

Compatibility with Other Formwork Systems

Our aluminium column formwork is designed to be compatible with other formwork systems, such as Exterior Wall Aluminum Formwork and Form Aluminium Formwork. This compatibility allows for a more integrated and efficient construction process. For example, the same connectors and accessories can be used for both the column formwork and the wall formwork, reducing the need for additional inventory and simplifying the construction management.

Durability and Reusability

Aluminium is a highly durable material, and our column formwork is designed to last for a long time. With proper maintenance, the formwork can be reused up to 200 times or more. The anti - corrosion coating and the high - strength alloy ensure that the formwork can withstand the harsh construction environment, including exposure to moisture, chemicals, and physical impacts.

The reusability of the aluminium column formwork not only reduces the cost of construction but also has a positive impact on the environment. By using reusable formwork, we can reduce the consumption of natural resources and minimize the amount of construction waste.

Conclusion

In conclusion, our aluminium column formwork offers a wide range of technical parameters that make it a superior choice for construction projects. From the high - strength material composition to the flexible dimensions, smooth surface finish, and easy assembly and disassembly, our formwork is designed to meet the diverse needs of the construction industry.
