How Are Aluminium Formwork Systems Made?

Must read

Aluminum formwork is a newer addition to the construction industry, and its primary components are, unsurprisingly, aluminum. Its resistance to dampness is a key feature that ensures the concrete keeps its structure from the moment it’s poured till it dries completely. Aluminum formwork systems are strong and long-lasting, but you can also use them multiple times.

What Is an Aluminum Formwork System?

The building industry has coined the term “aluminum formwork” to refer to aluminum alloy formwork. It’s the next step in formwork technology following wooden and metal systems. The aluminum framework is calculated by the modulus, is extruded using specialized machinery, and may be freely assembled in various configurations to accommodate a wide range of structural dimensions.

The building industry has seen significant change thanks to the design, development, and implementation of aluminum formwork. Housing construction ventures have benefited substantially from the aluminum formwork system’s increased efficiency, reducing costs.

The Aluminum Formwork Construction Requirements

Aluminum formwork reinforcement is by far the most popular option, and for a good reason: aluminum alloy formwork has several benefits, including easing the complexity of construction, cutting down on energy consumption and emissions, and protecting the environment. Remember this since it’s crucial. Let’s examine the need for aluminum formwork in the building process.

  • Measuring and releasing construction progress: the wall column’s axis, sideline, and thirty control lines were calculated and marked. If your wall reinforcement appears on the sideline after the wire has been loosened, leave a protective layer along that line.
  • You can use a level to determine if the floor is kept level to be within 8 mm. If it’s too long, it needs to be shortened. In addition, the base of an aluminum mold easily rots and leaks when filling it with concrete.
  • Chiseling, leakage, and cleaning the concrete surface poured at the construction junction are all necessary steps before setting up the formwork. The incorporated sections of the slanted roof are held in place by horse stool iron, which consists of 16-inch steel bars.
  • To begin situating the exterior walls, lighting shafts, and elevator shafts, you must enlarge the join layer in between the aluminum mold and wooden mold at an oblique angle, and you must punch the steel rods, particularly bay windows, which are very easily deformed).
  • Before the template is supported, a standard brush-release compound should be utilized. The release agent must be brushed evenly and freely across the top and bottom half of that template to prevent runoff into the ground. Remove the waste oil from an aluminum mold by any means other than scraping it off.
  • Wall positioning ribs, specifically their placement, should be welded and adhere to the following guidelines:

At each end and wall corner, there must be positioning ribs with a minimum pitch of 10 and no more than 450 mm between them horizontally.

Solid inner support should be installed every 900 millimeters at the shear wall’s terminal to ensure the shear wall’s required height.

Three durable high-wire metal rod positioning piles should be used to hold the aluminum mold along the outer walls, elevator shafts, and lighting shafts at the joint between the aluminum and wooden molds.

To ensure that the aluminum formwork will not be flawed during construction, it must undergo a thorough inspection beforehand. The aluminum formwork requires careful adherence to the implementation requirements during operation due to the high assembly accuracy required.
