Aluminum Wall Formwork is a modern construction system for forming cast in place concrete structure, widely used for casting concrete walls in buildings and structures. It is known for its lightweight, durability, and reusability, making it a cost-effective and efficient solution for construction projects.
Advantages of aluminium wall formwork
(1) Short construction period. Aluminium wall formwork is a quick-disassembly formwork system. One set of formwork can be completed in four to five days (one set of plate and three to six sets of support system). Moreover, it can be well implemented in assembly line construction, greatly improving construction progress and saving management costs.
(2) High number of reuses and low average cost of use. Aluminium wall formwork uses aluminum alloy materials formed by integral extrusion as raw materials. A set of aluminum wall formwork formwork can be flipped and used more than 300 to 500 times under standard construction.
(3) Convenient construction and high efficiency. Aluminium alloy building formwork system is simple and convenient to assemble. It can be assembled manually without the assistance of mechanical equipment.
(4) Good stability and high bearing capacity. At present, the bearing capacity of most aluminum wall formwork systems can reach 60kN/m2, which is sufficient to meet the formwork bearing capacity requirements of most residential buildings and has strong anti-deformation ability.
(5) Wide range of construction applications. Aluminium wall formwork is suitable for use in structural walls, horizontal floor slabs, frame columns, beams, stairs, window sills, floating boards and other locations. It can also be used for secondary structural formwork such as ring beams and structural columns.
(6) Few joints, high precision, and good concrete surface effect after demoulding. After the aluminium wall formwork is demoulded, the concrete surface quality is smooth and can meet the requirements of decorative finishes and plain concrete, reducing the consumption of raw materials such as finishing plastering and the man-hours for plastering.
(7) Less on-site construction waste and a simple support system. All aluminium wall formwork accessories can be reused. After construction and demoulding, there is no waste on site. The support system is simple in structure and easy to dismantle, making the entire construction environment safe, clean and tidy.
(8) Strong standardization and versatility. Aluminium wall formwork has many specifications and can be assembled with different specifications of panels according to the project; when the used formwork is used to renovate a new building, only about 20% of the non-standard aluminium wall formwork needs to be replaced, which can reduce costs.
(9) High recycling value. After the aluminium wall formwork is scrapped, the waste treatment residual value is high, and the cost amortization advantage is obvious.
(10) Low carbon emission reduction and energy conservation. All materials of the aluminum alloy building formwork are renewable and recyclable materials, which comply with the national regulations on energy conservation, environmental protection, low carbon and emission reduction of construction projects.
Technical points of aluminium wall formwork installation sequence
The installation sequence of aluminum wall formwork follows a systematic process to ensure precision and stability. The installation begins with the inner wall, followed by the outer wall. After placement, the vertical and horizontal elevations are adjusted to ensure accuracy.
For the inner wall formwork, installation starts either from the inner corner formwork or the wall head cover plate. Once the aluminum wall formwork is positioned along the control line, a release agent is applied to the wall formwork. It is then temporarily fixed using supports, with both sides of the wall formwork being installed simultaneously.
When installing aluminum alloy beam and slab formwork, the process involves assembling the beam bottom plate, beam side plate, top corner formwork, and wall top corner formwork in sequence according to the trial assembly drawing. This assembly is completed on the ground and then installed as a single unit. The formwork is fixed to the wall formwork on both sides through the corner formwork.
During installation, the bottom formwork is installed first, followed by the side formwork. The beam side formwork is mounted onto the beam bottom formwork and securely connected to the wall column using pins. After the beam side formwork is in place, the C groove at the bottom of the slab and the slab formwork keel are installed. This step-by-step approach ensures a seamless and efficient installation process.
