Five Types Of Formwork Systems Used For Different Purposes Formwork systems are moulds and support structures that make use of liquid concrete poured into moulds to build architectural structures when the concrete is hardened. Different types of constructions require the use of different types of formworks. The strength of a building, the speed at which it is made, and the cost of construction will depend to a great extent upon the type of formwork used in the construction. Read on to understand the differences between the five major types of formwork systems used for construction work.
Traditional Timber Formwork Systems: A combination of plywood and timber are used to create these traditional formwork systems at the construction location. Moisture resistant particleboards are prefab house
often used as a substitute for plywood for making formworks of this type. If you use traditional formwork for larger architectural structures, then it will take you a lot of time to complete the construction, even though it's very easy to produce. Re-Usable Plastic Formwork Systems: This type of formwork can be used again and again for constructing different types of architectural structures. These systems are modular and interlocking and are simple to use as compared to other types of formwork systems. Houses built under mass housing schemes often utilize plastic formworks as they are robust and lightweight. They help to incredibly lower the cost of construction as they can be re-used.
Engineered Formwork Systems: These types of formworks use metal frames for the prefabricated modules. Aluminium and steel are the common choices for metal frames used in engineered formwork systems. The use of engineered formworks can highly speed up any construction project, as compared to traditional formworks. The life-cycle cost of such formworks is low compared to other types of formworks as their metal frames cannot be damaged easily. Permanent Insulated Formwork Systems: Insulating concrete forms (ICF) are typically used to construct permanent insulated formwork systems. Such formwork is usually assembled at the construction site container house
. Once the concrete has been cured, this formwork stays in place. It is much stronger than other types of formworks and also enhances the speed of construction. Acoustic and thermal insulation offered by such formworks are higher compared to other types. Stay-In-Place Structural Formwork Systems: These formworks are assembled on location using plastic forms that have been reinforced with fibre and prefabricated for use. Piers and columns are often built using stay-in-place structural formwork systems. They are usually available in the shape of hollow tubes. As the name suggests, the formwork stays where it is following concrete cure. Shear and axial reinforcement is provided by these concrete formworks. They also protect the structure from environmental hazards such as freeze-thaw cycles and corrosion.
Now that you know about the different types of formwork systems, you must consult a professional formwork contractor or formwork supplier to select the right type of formwork suitable for your construction needs. The strength and durability of a building depends upon the formwork used, so make sure that the contractor you hire has in-depth knowledge and experience in this field and is able to give you the right advice.
