Aluminum formwork

 

 

Part one :Introduce of Aluminum formwork 

The Aluminium formwork born in the United States in 1962 has been widely used nowadays for global concrete structure in developed countries such as America and Canada newly industrialized countries such as Mexico, Brazil, Malaysia, South Korea and India after 50 years of development. Aluminium Formwork can be used more times compared with the traditional formwork. It is light with the average wight of 23 - 27 kg/m2, convenient to use and easy to install, thus saving the labor cost and shortening the working period. Meanwhile it makes the concrete surface flat smooth basically reaching the demand of veneer and water coagulation, which greatly improves the project quality.


Part two : Advantage of Aluminum formwork

Reusable

Antai Formwork can be used more than 300 times so ROI is maximised with multiple projects.

Lightweight

Average weight is only 23 - 27 kg M2 so no heavy lifting or cranes are required.

Simple to use

Can be assembled with non-skilled labour with simple training and no special tools required.

Fast build cycles

Typical cycle time of 1 floor every 4-5 days or 1 single storey house a day are achieved with Antai Formwork solutions.

Fully recyclable

Aluminium formwork is 100% recyclable at the end of its usability.

Reduce site rubbish

Constant reuse keeps the construction clean, safe and tidy.

Design flexibility

Antai design team are highly experienced in designing formwork solutions for multiple types of building and applications.

Strength & Stability

High load bearing capacity of up to 60 KN per M2 when assembled.

Finish quality

Achieves a high quality finish after formwork removal with only minimum "skim" coat required and no heavy plastering.

ECO-Friendly

Low carbon emissions

Reduce building costs

Substantial direct and indirect building cost reduction is achieved with Antai aluminium formwork solutions.

Part five : Components of Aluminum formwork

Wall Panel


 blob.png

Slab panel

The Slab panel will be used to support the concrete weight during concrete
pouring and casting

blob.png

 

Beam bottom
 slab panel

soffit Panel will be used to cover the
 bottom of the beam

Setting process of Aluminum formwork

Standard aluminum construction process:

Wall formwork → beam formwork → staircase formwork → formwork acceptance → concrete pouring → quality acceptance → demolition of the mold (first installed after the demolition) → transported to the next layer of construction.

Step of make Aluminum formwork

Aluminum formwork system construction preparation process is as follows:

The drawings completed→ drawings audit by the aluminum formwork technical engineers, offer → contract content confirmed, signed a contract → technical engineers design with mold designs (formwork assembly designs) → produciton according to the drawings → pre-assembled in factory → inspection qualified → delivery to construction site → working site construction.


(1) Standard production period of aluminum formwork from the deepening drawing design to trial assembly need 60 days;

 

(2) The drawings and plans provided to the aluminum formwork factory include: architectural drawings, structural drawings, decoration plans, hydropower plans, outer racks, laying holes etc .; drawings should be issued by the project department and have issued recording;

 

(3) After completion of the deepen drawing, the aluminum formwork factory should send the drawings to the project department, design department, wall panel factory, General contractor etc., the project department is responsible for organizing each department participate in the joint audit confirmation;

 

(4) After trial assembly aluminum formwork , the project department, the general contractor, the supervision and the engineering and technical department shall confirm the aluminum formwork node, the fastening system, the size deviation, the window (beam and wall) pressure groove etc.. If there have problem should email to related personnel;


(5) Aluminum formwork factory establish their own serial number coding map and number for each part of formwork ;


(6) The transfer of the aluminum formwork must be handled for three parties, the aluminum formwork transfer data: Die drawing, aluminum formwork serial number coding map, aluminum formwork fastening system drawing , aluminum formwork, three parties signed the receiving report, aluminum formwork construction technique hand-over.

 

(7) The first three floors of aluminum formwork must be carried out aluminum formwork precision inspection by third party before pouring concrete, aluminum formwork comprehensive accuracy are not less than 90%, single not less than 80%.
