Formwork and scaffolding are used in construction for different purposes. Formwork holds wet concrete in place until it hardens, while scaffolding is a temporary work platform used to reach heights. Scaffolding is made of panels, joints, and tubes and must be safe and sturdy. Formwork must be strong enough to support the weight of the concrete. Different types of scaffolding and formwork exist and are essential in civil engineering projects.
Formwork and scaffolding are used extensively in the construction industry for very specific functions. When construction crews need to shape wet concrete or hold it in place until it hardens into the desired shape, they use formwork. It can be defined as permanent or temporary casings or molds that hold concrete securely until it hardens enough to support its own weight. Scaffolding differs significantly from formwork; are temporary structures used as work platforms to support people during construction, maintenance or repair work and allow workers to reach heights that are otherwise not easily accessible.
Scaffolding is a modular system made up of panels, joints and tubes made from materials such as metal, wood or bamboo. Its design can be simple or complex, but in all cases its construction is done with great care because it supports groups of people on the go. It must be safe and sturdy and is used for a variety of purposes such as a platform for painting the exteriors of structures, acting as a temporary bridge or walkway, and for reinforcing props. Provides safety by providing handrails, acting as a ramp, or as a stabilizing or support structure for a building.
It allows workers to move around structures easily by giving them access to flat roofs and overhangs. Scaffolding is widely used to create stage sets for movies, make suspended platforms, or erect billboards. Formwork and scaffolding are indispensable in the construction industry due to the myriad ways they are used.
The formwork must have the required strength and be able to support the weight of the concrete it supports as the material sets. Wet concrete puts a lot of pressure on the formwork, putting more pressure at the bottom than at the top. If the formwork is not designed to support the required weights, it can bend or break as the concrete is filled.
Accidents can also occur when formwork is removed before the concrete has completely dried. Because of this, the formwork can remain in place for a number of days after the wet concrete is poured. Sometimes, a damp blanket is placed outside the molds for a while. Formwork is also known as shuttering or forms.
The two structures, formwork and scaffolding, are used for completely different purposes and have completely different needs. Scaffolding must be easy to construct, simple to dismantle and convenient to transport. Platforms built in scaffold must have areas large enough for people to walk freely and for materials to be easily moved and transported. The whole structure must be strong enough not to be affected by climatic conditions and not to shake, deform or tilt over time.
Scaffoldings are generally dependent structures; they are typically connected to a building or to a metal carpentry with the use of tie rods for stability purposes. Formwork and scaffolding also differ in type. These systems can be classified as reusable, structurally stable, engineered plastic formwork. Permanent insulated formwork and traditional timber formwork are other types of forms.
Birdcage, tethered freestanding, and saddle and roof pile are some types of scaffolding used. Scaffold towers, hanging bracket and putlog are other popular types of scaffolding structures. Formwork and scaffolding are vital structures in civil engineering projects and are used by millions of people worldwide.
