Formwork or moulds are an integral part of the construction industry. This casting material is generally made from wood. You can find these moulds made of different materials like steel, aluminum, plastic. The other commonly used word in the industry is called shuttering.
The primary parameter is that it should have the strength to carry the weight of the concrete once it is poured so that the structure does not collapse under the enormous weight. It has to be supported with enough framework at the bottom to give sufficient strength.
What Makes An Ideal Formwork?
In the beginning, we have talked about the prominent use of the formwork construction industry. Well, these not only work as a mould to define the structure but also choose the ideal formwork is paramount to get a strong finished product. There is a certain key characteristic that one must look into a formwork before choosing it:
The framework must be supportive of the weight of the concrete
It has to have enough supporting pillars such as timber pillars and supporting frames to ensure that the structure is stable for the two or three days when the concrete is setting down.
The sealing of the joints should be flawless, or else it can result in leakage of cement
The surface should be smooth
It should be light in weight
The material should be easily accessible
Detailed Overview Of The Key Features Of Formwork
After all, you don’t want any mishappenings, right? The contractor pays special attention to the framework and its supporting frames and edges to easily bear the weight of the concrete.
Easy Demetallation Of The Framework After Pouring The Concrete
Of course, the framework should be supporting enough, but then the formwork structure should be such that it is easy dismantled. This is why you will generally see plastic laid on top of the structure to ensure that the concrete, once it dries out, does not stick onto the surface of the concrete structure.
It should be easy to dismantle without any harassment. Talk to your concrete contractor about this to not cause any damage to the concrete structure.
The Concrete Should Have A Well-Defined Structure For Supporting The Individual Framework Weights
The structure of the formwork, as we have talked about, should be supporting the individual areas. See, as per the construction design of the structure being made, there will be more weight and less weight.
The civil contractors and engineers working on the basic foundation and structure design should choose the right structure to support the weight.
Thus the areas of more concrete weight have to be identified, and then the formwork construction shape and structure should be more supportive and immaculately planned.
Choose the Material Of The Framework As Per The Dimensions Of The Structure
The material of the formwork plays an important role in creating the final structure. Hence the contractor must choose the right material. The ideal choices are wood and metal.
You will see that the larger structures, such as larger several storied buildings, will have their formwork made out of stronger steel frames and rods. On the other hand, the smaller buildings, which are generally two to three-storied high, will have a structure made out of wood only.
Deflection in Shape And Structure Should Be Minimum While Pouring The Concrete On It Due To Weight
The deflection of the formwork has to be less when the construction or pouring of concrete is going on. This is one of the most important criteria when the actual work is going on.
