How to install aluminium formwork?

As a trusted supplier of aluminium formwork, I'm excited to share a comprehensive guide on how to install aluminium formwork. Aluminium formwork has gained significant popularity in the construction industry due to its durability, reusability, and cost - effectiveness. In this blog, I'll walk you through the step - by - step process of installing aluminium formwork, ensuring that you can achieve a smooth and efficient construction project.

1. Preparation

Before starting the installation, thorough preparation is crucial. This stage sets the foundation for a successful installation process.

Site Inspection

First, conduct a detailed site inspection. Check the ground level to ensure it is flat and stable. Any unevenness can lead to problems during the formwork installation and may affect the quality of the final concrete structure. Measure the dimensions of the construction area accurately. This will help you determine the quantity and type of aluminium formwork panels required.

Material and Tool Gathering

Gather all the necessary materials and tools. As an aluminium formwork supplier, we offer a wide range of products such as Kumkang Aluminium Formwork, Aluminium Wall Formwork, and Aluminium Column Formwork. Make sure you have the correct panels, connectors, braces, and other accessories. Tools like wrenches, hammers, and measuring tapes are essential for the installation process.

Panel Cleaning and Assembly Planning

Clean the aluminium formwork panels to remove any dirt, debris, or rust. This will ensure a smooth surface for the concrete pour. Then, plan the assembly of the panels. Lay out the panels on the ground according to the construction plan, and mark the positions of the connectors and braces. This pre - planning will save time during the actual installation.

2. Installation of the Base Formwork

The base formwork provides the support and stability for the entire structure.

Setting the Corner Panels

Start by setting the corner panels. These panels are the key to defining the shape of the structure. Use a spirit level to ensure they are perfectly vertical. Secure the corner panels to the ground using appropriate fasteners. This will prevent them from shifting during the installation of the remaining panels.

Connecting the Side Panels

Once the corner panels are in place, connect the side panels to them. Use the provided connectors to join the panels together. Make sure the connections are tight and secure. Check the alignment of the panels regularly using a measuring tape and a straightedge. Adjust the panels as needed to ensure a straight and even surface.

Installing the Braces

After connecting the panels, install the braces. Braces are used to provide additional support and stability to the formwork. Place the braces at the appropriate intervals and secure them to the panels and the ground. This will prevent the formwork from collapsing or deforming under the weight of the concrete.

3. Installation of Wall and Column Formwork

Wall and column formwork are critical components of the construction.

Wall Formwork Installation

For wall formwork, start from the bottom and work your way up. Connect the wall panels to the base formwork using the connectors. Use vertical and horizontal braces to support the wall formwork. Make sure the wall formwork is plumb and level. This will ensure that the concrete walls are straight and have the correct dimensions.

Column Formwork Installation

Column formwork installation requires precision. First, assemble the column panels around the column reinforcement. Use special column clamps to secure the panels together. Check the alignment of the column formwork using a plumb bob. Make sure the column formwork is centered and vertical. Then, install the braces to support the column formwork and prevent it from tilting.

4. Installation of Beam and Slab Formwork

Beam and slab formwork are used to create the horizontal surfaces of the structure.

Beam Formwork Installation

Install the beam formwork after the wall and column formwork. Place the beam panels on the supporting brackets. Connect the beam panels together and secure them to the wall and column formwork. Use props to support the beam formwork at the appropriate intervals. Check the level of the beam formwork to ensure that the concrete beams will have the correct slope and elevation.

Slab Formwork Installation

For slab formwork, lay the slab panels on the supporting beams. Connect the slab panels together to create a continuous surface. Use props to support the slab formwork. The spacing of the props should be determined based on the load - bearing capacity of the formwork and the thickness of the slab. Check the level of the slab formwork to ensure a flat surface for the concrete pour.

5. Checking and Adjusting the Formwork

After installing all the formwork, a thorough check and adjustment are necessary.

Alignment and Level Check

Use a measuring tape, a straightedge, and a spirit level to check the alignment and level of the formwork. Make sure all the panels are in the correct position and that the formwork is level. Adjust the formwork as needed by tightening or loosening the connectors and braces.

Connection Check

Check all the connections between the panels, braces, and connectors. Make sure the connections are tight and secure. Replace any damaged or loose connectors. This will ensure the integrity of the formwork during the concrete pour.

Reinforcement Check

If there is any reinforcement inside the formwork, check its position and spacing. Make sure the reinforcement is properly placed and tied. This will ensure the strength and durability of the concrete structure.

6. Concrete Pouring

Once the formwork is installed and checked, it's time to pour the concrete.

Pouring Process

Pour the concrete into the formwork slowly and evenly. Use a concrete pump or a chute to transfer the concrete to the formwork. Avoid pouring the concrete too quickly, as this can cause the formwork to deform or collapse. Use a vibrator to compact the concrete and remove any air bubbles.

Monitoring the Formwork

During the concrete pouring process, monitor the formwork closely. Check for any signs of deformation, such as bulging or shifting. If any problems are detected, stop the pouring immediately and make the necessary adjustments.

7. Formwork Removal

After the concrete has cured, the formwork can be removed.

Curing Time

The curing time of the concrete depends on various factors, such as the type of concrete, the temperature, and the humidity. Generally, the formwork can be removed after the concrete has reached a certain strength. Consult the concrete supplier or a structural engineer to determine the appropriate curing time.

Removal Process

Start by removing the braces and connectors. Then, carefully remove the panels from the concrete structure. Be careful not to damage the concrete surface or the formwork panels. Store the removed formwork panels in a dry and safe place for future use.
