In construction, a concrete formwork is used to support a structure and mould in order to create structures out of concrete that is poured into the mould.
There are various kinds of formwork that are often used in construction area. Each of them differs according to the challenges in the area, as ell as building requirements. It is used by creating a mold out of steel, wood, aluminum, or some prefabricated forms to which the concrete is then poured. This is left to harden and set. After that, it will be stripped. But in the case of stay-in-place types of formwork, it will be left as part of the structure.
With the help of a formwork, contractors are able to cast and construct the main parts of a building which need to be strong and be capable of supporting other structures like the walls and floors, as well the other smaller parts like the stairs.
Different Types of Formwork
There are various kinds of concrete formwork to choose from. One is the traditional timber type which makes use of plywood and timber to form mould for pouring. Choosing this method is cheaper compared to other methods. However, it may not be as effective because wood, compared to steel or metal is not that strong. But if there are complicated sections of buildings that need careful attention to detail, then timber formwork is good to use.
An engineered formwork system makes use of a prefabricated mould from a metal frame. It can either be aluminum or steel. This type of formwork is cheaper and easier to use than a traditional one. The frame is highly strong and does not require so much replacement which equates to more savings. Additionally, since it is engineered, the construction is so much faster and needs lesser manpower, which again, means saving money. Using a reusable plastic formwork system, simple structures can be built and this consists of lightweight yet strong interlocking systems.
This type is generally used to support parts of a whole structure. It consists of insulating concrete forms that are filled with reinforced concrete. Once they are set, they are left in place.
Today, formworks are widely used in the field of construction. Given that there are so many types available that one can choose from, building any project is made possible because of the various methods that can be applied to obtain the desired results. When properly reinforced, concrete can be a virtually indestructible material which will be prefect for any major construction work, whether it’s small, complex, or detailed structure. This is why it has been a must in construction as it has been very instrumental in achieving projects and quality results.
