Formwork is a sort of complex technique that comes in handy in the construction sector. If you need to get such work done the best option for you would be the formwork companies in Sydney. These are specialists in such work and you can be sure that you would not be able to get such work done without their help. The term denotes certain receptacles as well as moulds. It is into these that the construction professionals pour the concrete. The main intention here is to create slabs for construction. In fact, actual components for buildings are also built by using formworks.
After the concrete becomes sufficiently hard the construction professionals take the forms away. The formwork contractors in Sydney refer to this particular process as stripping:
- Various kinds of formworks:
These days, construction professionals use various types of formworks in buildings. It also needs to be said that these people use them for various other purposes as well. There are three main materials that are useful for such purposes.
- We may count them as below:
- timber formwork
- engineered formwork
- stay in place formwork systems
The timber formworks are the traditional options in this regard. The engineered formworks are basically metal frames. The stay-in-place formwork systems are basically concrete systems that happen to be premade.
It is by using these frameworks that formwork companies in Sydney come up with various ways in which they create various structures and slabs:
- A brief history of these formworks:
The process of making formworks was started by Roman engineers. They did this in order to finish major constructions where they needed concrete. The engineers in that era used the likes of arches and domes in order to support their construction for the simple reason that concrete is not highly resistant to stress. It was only after reinforced concrete was invented that concrete became a popular material as such.
- The traditional formworks:
The three main kinds of formworks used by formwork contractors in Sydney have already been enumerated above.
Conventional slab formwork uses ingredients such as the following in order to complete the construction work:
- timber
- masonry
- carpentry
In this particular method supporting rows of stringers made up of materials such as tree trunks and other forms of lumber are used. They are normally placed at a distance of 6 feet or a couple of metres apart from each other. Normally joints are placed between the stringers as well.
- The metal formworks:
The slab formworks made of metal beams are pretty much the same as their conventional counterparts. The only difference of note between the both of them is that in the case of the earlier steel is used rather than timber. They also use metal props rather than stringers as is the case with the latter – yet another major point of difference. You would find a lot of formwork companies in Sydney using them for the simple reason that they happen to be capable of being used time and again. It is also a lot more methodical than the traditional method.
