Type C Alu Formwork

Short construction period. The aluminum formwork system is a quick-release formwork system. The normal construction of a set of formwork can reach one level in four days, and the pipeline construction can be better carried out, which greatly improves the construction progress and saves management costs.

There are many times of repeated use, and the average use cost is low. The aluminum formwork system uses the aluminum alloy profile formed by the overall extrusion as the raw material, and a set of formwork can be used over 300 times for standard construction. The purchase price of a set of templates is amortized, which saves a lot of cost than traditional templates.

Convenient construction and high efficiency. The aluminum formwork system is simple and convenient to assemble, with an average weight of about 20kg. It is completely handled and assembled by hand without the assistance of any mechanical equipment. Moreover, the system design is simple, and the workers can get up to speed quickly. Skilled installers can install 20-30 square meters per person per day, greatly saving labor costs.

Good stability and high bearing capacity. The bearing capacity of most aluminum formwork systems can reach 60KN per square meter, which is sufficient to meet the supporting capacity requirements of most residential building groups.

Wide range of applications. Aluminum formwork is suitable for the use of walls, horizontal floors, columns, beams, stairs, windowsills, flaps, etc., and it is also useful for secondary structural support such as ring beams, structural columns, and anti-bumps.

Less joints, high precision, good concrete surface effect after demoulding. After demolishing the aluminum building formwork, the surface quality of the concrete is smooth and smooth, which can basically meet the requirements of facing and clear concrete, without the need for batching, which can save the batching costs.

The construction site has less waste and the supporting system is simple. Aluminium Formwork Accessories can be reused. After the construction is demolished, there is no garbage on site. The support system has a simple structure and is easy to remove. Therefore, the entire construction environment is safe, clean and tidy.

Strong standard and universality. There are many specifications of aluminum formwork, which can be assembled with different specifications according to the project. When the used formwork is used to rebuild a new building, only about 20 non-standard boards need to be replaced, which can reduce costs.

High recycling value. After the aluminum formwork is discarded, when the residual value of the waste treatment is high, the cost sharing advantage is obvious.

Low carbon emission reduction. All materials of the aluminum formwork system are renewable materials, which meet the national regulations on energy conservation, environmental protection, low carbon and emission reduction of construction projects. 

Question: The strength of aluminium formwork profile may not meet the requirements and they are prone to deformation during the construction process.

Solve: Prior to installation, it is imperative to conduct a strength acceptance test on the aluminium formwork profile to ensure its compliance with prescribed standards. It is recommended to employ aluminium materials from the 5-series or 6-series due to their heightened strength and durability.acceptance tests should be conducted on weld seams, joint widths, pins and wedges. Weld seams need to undergo a thorough inspection of welding processes and quality to ensure strong and reliable joints. Joint widths should conform to design requirements to avoid construction difficulties or quality issues caused by excessive or insufficient widths. The quality and dimensions of pins and wedges should also be verified to ensure the effective connection of components of aluminium formwork.

Question: The aluminium formwork system might suffer from inadequate overall rigidity due to the large number of small panels used in construction.

Solve: The aluminium formwork system(aluminium formwork system) is assembled with aluminium alloy plates to form a complete framework, featuring a high bearing capacity reaching 30-40kn per square meter. However, the use of a large number of small plates may result in inadequate overall rigidity, leading to structural deformation. During the aluminium formwork design calculation, non-standard formworks design should be attention such as beam-column and beam-wall joints as well as the formwork design for the lower edges of wall corners to optimize the overall structural rigidity and reduce the risk of deformation.

Question: The concrete surface detachment after the formwork for aluminium was dismantled

Solve: Before using formwork for aluminium, it is essential to apply form release agents every time. This practice effectively prevents adhesion between concrete and formwork for aluminium, ensuring a smooth concrete surface during dismantling. We recommend choosing a water-based form release agent as it is environmentally friendly and easy to clean. When applying the form release agent, it should be brushed from top to bottom. This method ensures thorough penetration of the release agent and minimizes waste and ineffectiveness during application.

Question: During aluminium formwork in construction, leakage at the joints will result in honeycombing on the surface of the concrete, which seriously affects the appearance of the structure.

Solve: In aluminium formwork in construction, if the cement residue is not properly cleaned or if the joints are not tightly sealed, it may lead to leakage. Therefore, immediate cleaning is necessary after the removal of aluminium formwork panels. The purpose of cleaning aluminium formwork panels is to ensure optimal construction results and prevent the occurrence of grout leakage issues during future use. The cleaning process involves the thorough removal of residual cement and other contaminants from the edges, as well as addressing any joint-related concerns. Furthermore, any deformed or damaged used aluminium formwork should be promptly sent back to the manufacturer for repairs, in order to prolong its service life and reduce subsequent maintenance costs.

Question: the columns, walls, and stairs were displacement.

Solve: If the displacement is within the allowed range (≤5mm for columns and ≤3mm for walls), no further treatment is needed. If the displacement exceeds the allowed range (5mm ≤ column ≤25mm and 3 mm ≤ wall ≤15mm), To address this issue, it is possible to install kicker in aluminium formwork, which should be affixed to the structure. When dismantling the lower wall panels, it is crucial to refrain from removing kicker in aluminium formwork.
