Architectural Aluminum Formwork

Speed of Construction
Aluminum formwork enables faster construction cycles, as the panels can be quickly assembled and disassembled. This speed is particularly advantageous in multi-story buildings where repetitive construction cycles are common.

High-Quality Finishes
The use of aluminum formwork ensures a smooth and high-quality finish for concrete surfaces. This reduces the need for additional plastering or finishing, leading to cost savings and a better aesthetic appearance.

Durability and Reusability
Aluminum formwork is highly durable and can be reused multiple times, making it cost-effective over the long term. In multi-story buildings, where uniformity and repetition are key, this feature is especially valuable.

Precision and Accuracy
The formwork system is designed to precise measurements, ensuring that each floor of the building is constructed with uniformity and consistency. This precision helps in maintaining structural integrity and quality control.

Reduced Labor Dependency
Aluminum formwork systems are relatively easy to assemble and require less skilled labor compared to traditional formwork systems. This is beneficial in regions where skilled labor may be scarce or expensive.

Lightweight and Easy Handling
Aluminum panels are lightweight, making them easy to handle and transport on-site. This reduces the strain on workers and improves safety, particularly in high-rise construction.

Structural Strength
The use of aluminum formwork allows for monolithic concrete structures, meaning walls, floors, and columns can be cast in a single pour. This results in stronger and more stable structures, which is critical in multi-story buildings.

In formwork erection
– The difficult weakness of aluminum formwork is that it cannot prevent the horizontal pushing pressure on the wall on the boundary beams of the project, only connecting the 3-sided latch, while the top edge is free. According to practical experience, the following measures have been applied:

+ Pulling the edge to the edge of non-ferrous steel welded to the floor steel (applicable to all projects)
+ Reduce the size of the top steel rod (tie) by 5mm (FEV project – 04 block, District 2, Ho Chi Minh city)
+ Pull the end of the side wall made of 8mm steel welded to a section of steel bar, then anchor the anchor to the inner floor plate
+ Getting the steel bar to be pierced from the side wall, diagonally down to the inner plate (rarely used)
+ The phenomenon of floor expansion (usually from the second floor): common for large floor areas (post-stressed floors, load-bearing flat floors …. When installing full-floor formwork, the floor system is swollen. or failure to install the end panels There are many causes, the most common being:
+ After many floors of construction, the formwork is soiled with concrete between the edges, when connecting the components will no longer be tight and lead to errors, so many panels, the error rate increases => need cleaning , immediately after concreting and dismantling.
+ The excessive use of old recycled panels.
+ Construction and maintenance work is not good.
+ The most optimal remedy is still in the stage of ensuring construction techniques, preserving and cleaning aluminum formwork. Avoid damage caused by disassembly. Oil must be applied to the concrete contact surface and also to the bonding edges. When installing the floor, it is recommended to install it from the edge to the inside, from the edge to the center.
+ Gathering aluminum formwork in the wrong position, wrong item, prolonging construction time.
+ Aluminum formwork panels are warped due to improper removal by workers.
+ Damaged concrete and formwork due to forgetting to insert steel rollers, installing mules in insufficient quantity, not following approved measures.
+ Spilled concrete at the landing, due to improper construction techniques and forgetting to seal the steel mesh, the position of the landing on the stairs intersects with the adjacent wall.
+ Concrete clings to the formwork surface due to inadequate and untimely cleaning.
+ Workers often forget or intentionally do not oil the formwork surface before installation.
+ Faulty mounting steel (fired steel), affecting the installation progress of formwork.
+ A part or the whole of the formwork is broken, the formwork or the tool falls from a height, the cause can be:
+ Due to the leveling and compaction of the ground to prevent settlement and ensure good drainage.
+ Because the columns or scaffolding frames are not vertical, bracing is not required by the design.
+ Because the foot of the column has no anti-sink, anti-slip board, the footrest made of stone bricks or wood chips is not enough to prevent settlement.

In the dismantling of formwork
– Removed earlier than specified and calculated, leading to impact on concrete and structure.
– While dismantling the formwork, the person who is not supposed to walk under the removed formwork should not be immediately transferred to the ground, piled on the scaffolding, may slide down or break the scaffolding because of the heavy weight. .
– Plunging the formwork from above even if there are no people on the ground is also very dangerous.

Construction projects utilize two popular types of formwork systems: steel frame formwork and aluminum formwork. Although both have their own advantages and disadvantages, they differ significantly in terms of properties and applications. A significant distinction between steel frame formwork and aluminum formwork lies in the materials used for their construction. Steel frame formwork boasts steel frames, providing exceptional strength and durability, making it suitable for heavy-duty projects like high-rise buildings, bridges, and dams.

Aluminum formwork is composed of lightweight aluminum panels, making it more suitable for low-rise and mid-rise constructions. The weight of the formwork system differs. Steel frame formwork is relatively heavier than aluminum formwork. This can be advantageous in situations where additional weight is necessary to counteract external forces such as wind or seismic loads.the weight of steel frame formwork can pose difficulties in handling and transportation, requiring more labor and machinery. In terms of versatility, steel frame formwork offers more flexibility in customizability and adaptability. Steel frames can be easily modified or adjusted to accommodate various shapes, sizes, and complex architectural designs.aluminum formwork is limited in terms of customization due to its lightweight nature, making it better suited for standard-sized structures or repetitive construction patterns. Cost is another important factor to consider. Steel frame formwork tends to be more expensive due to the higher cost of steel and the additional labor required for handling and installation.steel formwork offers a longer lifespan and can be reused multiple times, offsetting the initial investment over multiple projects. Initially cheaper, aluminum formwork may need to be replaced more frequently due to wear and tear, making it a more costly option in the long run.the choice between steel frame formwork and aluminum formwork depends on the specific requirements of the construction project. Factors such as project scale, complexity, budget, and desired lifespan should all be taken into account when selecting the appropriate formwork system. Consulting with construction professionals and engineers is advisable to determine the most suitable formwork system for each unique project.
