The various types of wall formwork can be classified based on their structure and materials. However, their installation process is generally similar. Taking aluminum wall formwork panels as an example, we will provide a more detailed explanation of the construction process to assist users in their construction.

● wall formwork system installation requirements

1、 Once assembled, check if the numbers on the wall formwork system match those on the installation drawings.

2、 To ensure a successful installation and adjustment of the wall formwork system, it is important to establish the axis line of the column or wall before starting the installation process.

3、 During the installation of the wall formwork system, it is necessary to install push pull prop according to the wall formwork drawing. Additionally, anchor bolts should be embedded before pouring concrete to enhance the strength and stability of the support structure.
4、If the wall formwork system is damaged, it should not be used. A thorough inspection and evaluation must be conducted to develop an appropriate repair plan, ensuring construction quality and safety.
5、 When storing the wall formwork system, make sure to follow the specified guidelines. If you need to stack them, place wooden spacers between layers to prevent damage or distortion caused by an uneven balance. The bottom layer of the wall formwork system should be elevated at least 10 centimeters from the ground, which helps avoid problems such as moisture damage or contamination.
6、Conduct an acceptance check on the reinforcement bars and embedded components to ensure that the installation meets construction standards.
7、 Ensure that the construction joints for concrete have been cleaned. Additionally, remove any excess slurry to ensure that the concrete surface is smooth and even

● formwork for wall installation

1. When you start installing formwork for wall, you need to draw control lines and install boundary lines for shear walls according to the building's axis line.

2. Before installing the formwork for wall, it is important to thoroughly clean the contact surfaces and edges of the formwork for wall and apply a release agent to prevent cement adhesion.

3. Install one side of the formwork for wall according to the positioning lines. Then, install wall formwork accessories(including concrete formwork wall ties, concrete wall formwork spacers, pins and wedges, and plastic sleeves). The specifications and spacing of concrete formwork wall ties should comply with the regulations specified in the wall formwork calculation.

4. Install the other side of the formwork for wall and adjust the push-pull prop to ensure that the formwork for wall is vertical. Tighten the nuts to ensure horizontal alignment.

5. Make necessary adjustments to the positioning of the reinforcement bars within the formwork for wall, and confirm that the protective layer has the appropriate thickness.

6. After the installation of formwork for wall, inspect whether the wall formwork accessories are securely fastened and if the joints are tightly sealed.

Note: Please remember to install the formwork for wall in the following order: start with the internal walls before moving on to the external walls, and prioritize horizontal walls before vertical walls.

● wall kickers formwork installation

1. wall kickers formwork is utilized to create a connection between different floors In certain areas like elevator shafts and exterior walls.

2. Before the completion of concrete pouring on the first floor, it is necessary to install wall kickers formwork as the starting point for the next layer of girder wall.

3. To connect wall kickers formwork with girder wall formwork, pins and wedges are used. Install M16 bolts at the bottom position of wall kickers formwork for securing, and these bolts will be anchored in the hardened concrete.

4. After the concrete is poured, if needed, The levelness of wall kickers formwork can be adjusted by adjusting the bolts. These adjustments significantly improve the quality of the wall.

● shear wall formwork remove

1. In general, after 12 hours of concrete pouring, the shear wall formwork can be removed. Start by removing the push-pull prop first, and then proceed to remove the wall tie for formwork.

2. Loosen the nuts with a wrench, remove the washers and steel waler, and tap one end of the wall tie for formwork gently until it comes out of the concrete.

3. Remove the pins and wedges that connect the shear wall formwork, then use a crowbar to pry and detach the shear wall formwork from the wall.

4. Clean up the removed shear wall formwork and wall formwork accessories, and promptly transport them to the same position on the previous floor, neatly stacked and laid flat.

● formwork for wall construction acceptance

1. After finishing the installation of all formwork for concrete wall, it's important to carefully examine and repair joints to ensure no leakage occurs. To avoid any weak spots due to leakage during concrete pouring, mortar should be used to seal the perimeter of the formwork for concrete wall.
2. The surface of formwork for concrete wall needs to be coated with a release agent.
3. During the installation of formwork for concrete wall and shoring props, it is necessary to set up temporary stabilization measures to prevent overturning.
4. The installation of embedded components such as plumbing and electrical equipment must be handled by a designated person. They should ensure accurate positioning, avoid omissions or misplacements, and ensure secure installation.
5. During concrete pouring, a designated person should be assigned to constantly monitor the support system of the formwork for concrete wall and make necessary adjustments and reinforcements as needed.

● wall formwork for sale Maintenance

1. If the wall formwork for sale encounters any issues, it must be immediately stopped and promptly repaired. Additionally, make sure to prevent the surface of wall formwork for sale from being affected by dust or other pollutants to maintain its proper functioning.
2. If you frequently use wall formwork for sale in high temperatures and humid environments, it can damage its structure and reduce its performance. Therefore, pay attention to the environment in which it is used, particularly with regard to storage in high-temperature and humid conditions. If you notice any signs of aging or damage to the wall formwork for sale, make sure to replace it right away.
3. Do not pour any liquids onto the surface of wall formwork for sale. This can cause cracks inside and reduce its effectiveness
