Exploring Innovative Formworks Inspired by Modern Construction Trends
Formworks have long been an integral part of remarkable concrete constructions. Be it the ancient Roman architects or the modern builders, everyone associated with the task of erecting magnificent structures finds formworks indispensable.
Over the centuries, the methods and requirements of construction have changed. Therefore, the formworks have also undergone significant changes to meet the evolved and altered construction requirements.
Builders and designers today can work with experimental ideas and unique architectural designs because there exist suitable formworks for those construction works. The history of formworks began ages ago.
But, initially, timber forms were more dominant in use. Even the architectural marvels of the ancient world like the Pantheon or the aqueducts made by the Romans depended on timber forms for their construction. But, timber forms also have a downside – they are not sustainable. Timber forms feature wood that essentially comes from trees.
Therefore, felling trees remain intrinsically associated with timber forms. With the current rate of green cover loss in the world, felling trees would only mean aggravating the problem. Therefore, the formwork manufacturers invented new ways to make durable formworks.
This effort, combined with scientific advancement resulted in the manufacturing of metal formworks, Mivan Shuttering, alloy forms, fabric forms, and plastic forms.
Modern Construction Requirements
The best formwork for any construction project is the one that helps build the structure flawlessly and faster. Therefore, speed and accuracy are the two aspects the modern builders keep in mind while using formworks.
Keeping this consideration in mind, the best formwork manufacturers came up with plastic formworks. These formworks are durable, recyclable, and can be used for several projects.
Traditional Vs. Modern Forms
Timber forms were extremely useful but they were susceptible to erosion due to climatic conditions. Of late, construction works go on everywhere and builders need formworks that can withstand heat, moisture, rain, and cold. Initially, timber was replaced by aluminum, steel, etc. However, metals were not corrosion-resistant and alloys sometimes failed to meet multiple construction site requirements.
- Expandable Modular Forms: This is why the formwork manufacturers came up with plastic forms that are lightweight, easy to install, and can withstand extreme weather conditions.
Making modular formworks that could meet the varying requirements of multiple construction sites at the same time became easier with plastic forms. A few easy-to-use clasps and locks are enough to extend a plastic formwork.
- Eco-friendly: Unlike earlier, people are now becoming more aware of the dangers of exploiting natural resources indiscriminately. Therefore, felling trees or mining metals are gradually becoming unpopular ways to collect materials for manufacturing formworks.
As an alternative, plastic has replaced these materials quite efficiently. Plastic forms are way more eco-friendly and generate negligible amounts of construction site waste.
- Reusable: Compared to any other traditional formwork variety, plastic forms are way more reusable. A single formwork can remain useful for 200+ projects.
Once the service life of the form is over, it does not end up in landfills. Instead, these discarded formworks undergo recycling and modification to gain refreshed utility.
NovaFormWorks is a reputed plastic formwork manufacturer in India. They also deal in aluminum formworks. You can check the collection of plastic forms in its collection to buy one. Customization options are also available with Nova.
Loads and Pressure on Concrete Formworks – An Understanding
Forms bear a lot of pressure and exertion throughout their service life. The construction sites generally keep the forms exposed to harsh and challenging conditions both externally and internally.
From withstanding the gusts of wind to bearing the load of machinery, drilling friction and more, the best formworks need a sturdy build to remain intact and perform optimally. The following is a list of different loads a form might experience during a construction process.
Vertical Load
The vertical load experienced by a formwork can be of two varieties – dead load and live load. Formwork load, moulded fresh concrete, and steel enforcements are a few varieties of dead loads that a formwork might experience. The dead loads are permanent loads which result from the weight of the structure itself or from other permanent attachments, for example, drywall, roof sheathing and weight of the truss.
On the other hand, the weight of the equipment, tools,material storage, and runways, and accelerating and braking forces from buggies and other placement equipment, and workers are some of the live loads the structure experiences. Therefore, the best formworks must be strong enough to withstand all these and more. According to the specific guidelines, forms made for allowing labours to use screeds, hoses, and vibrators should bear 2.4Kpa live load.
If the construction process involves buggies or motorized vehicles, the load should be 3.6 Kpa. The guidelines further specify that the combined load of dead and live load should be between 4.8 Kpa and 6 Kpa for sites using motorized instruments.
Lateral Pressure Of Concrete
Lateral pressure is another critical factor for calculating the overall load requirement of a form structure. Forms made of any material remain exposed to several types of pressures and loads of which lateral pressure remains an unavoidable one.
Mostly, when concrete placing takes place, the friction generated increases the lateral pressure. Additionally, lateral pressure may alter due to several other factors such as concrete temperature, placement rate, and internal frictions.
Therefore, different construction sites require different lateral load adjustments for specific forms. Formwork in construction remains indispensable and to make durable and pressure-resistant forms, the manufacturers should take care of the lateral pressure calculation diligently.
Horizontal Loads
Wind, equipment stopping and starting, concrete dumping, and inclined supports remain some of the most common sources of horizontal loads. Therefore, the best form manufacturer in India pays enough attention to the fact that the structures remain braced against such loads.
Generally, for a large building, the horizontal load remains 2% of the entire dead load or 1.5 KN/mtr., of the edge of every floor. Depending on the pressure a particular form is expected to experience at a certain location or area, the form bracing should be done.
Special Loads
All construction sites do not operate the same way. Therefore, the load experienced by the form also remains substantially different for different sites.
A few varieties of construction conditions like loads due to reinforcement concentrated, machine-delivered concrete impact, unsymmetrical concrete placement, loads due to form handling, uplift, etc., remain quite uncommon.
However, if a construction site deals with any of these conditions, the forms need to be constructed accordingly.
NovaFormWorks is one of the formwork manufacturers in India. Its range of eco-friendly, reusable, durable, and modular plastic forms remains one of the most popular choices of modern construction companies.
Can Plastic Formwork Replace Wood And Steel Formwork?
Formwork in construction is undoubtedly an indispensable element. Traditionally, wood forms, metal forms, etc., dominated the market. However, today, plastic formworks have gained adequate popularity due to their superior features.
Several construction sites have switched from conventional varieties to the latest plastic alternatives. The following are a few aspects that make plastic formworks a perfect and often a superior alternative to the conventional wood or steel form.
1. Easily Stackable
Stacking one plastic formwork atop another is hassle-free. These lightweight structures do not transfer much pressure down the piles. Additionally, you can store these piles of forms inside or outside the site. Plastic does not erode easily when exposed to climatic conditions.
Therefore, you do not have to bother about protecting these piles from rain or sunlight. These UV-resistant forms remain in perfectly good shape and condition even when you keep them in basements that often get flooded with water.
2. Easy Access Tie-Rods Opening
Plastic formworks save you the effort of drilling as they come with several caps and plugs for easy installation. This is the best shuttering for Foam concrete as foam concrete is liquid and due to the good locking system there is no leakage between the panels. Nova Formworks have a prefixed frame which acts as a stiffener which is hollow and light weight , in cases where load taking capacity is to be increased the thickness of these stiffeners can be increased.
3. No Need For Shuttering Oil
One of the most beneficial features of plastic form remains that these do not stick to the concrete surface as it hardens. Therefore, you do not need extra hands or time to detach the concrete surface from the forming surface. Consequently, the construction process becomes hassle-free, faster, and cleaner. As one of the best formworks available today, plastic forms offer a smooth and uniform cement-rich concrete surface finish that lasts for a longer life.
4. Easy-To-Use
Plastic forms weigh less and feature easy-to-lock wedges and pins that make using them hassle-free. Therefore, even labours with no prior experience in handling forms can handle these forms without much difficulty. Thus, plastic formwork in construction reduces the overall labour cost and saves a lot of time.
5. Reduced Surface Tension
Plastic formworks come with very low-level surface tension. Since plastic forms do not stick to the hardened concrete surface, removing and reusing the form becomes an easier, labour-saving, cost-effective, and time-saving option. Nova Formworks increases the strength and quality of Concrete as there is no leakage, no water absorption thereby enhancing the curing of Concrete
6. No Plastering
When construction sites used wood or steel forms, plastering used to be an unavoidable work before painting the concrete surface. With plastic forms, the surface becomes so smooth that you do not need plastering at all. This reduces the overall cost substantially.
7. Cost Effective
Plastic forms are considered the best formworks as these ensure low-cost construction. You can reuse a plastic form more than one hundred times if you handle it properly. Nova Formwork System does not require heavy machinery like a crane for lifting as this system is lightweight and can be easily handled by labour at site.
8. Scrap Value
Even after using the plastic form over 200 times, the structures do not get eroded. Given the resilience of plastic, Nova Formworks System reduces on-site wastage and shuttering debris and keeps the construction site clean and safe.
9. Carbon Credits
Many companies and construction sites prefer using greener alternatives keeping the carbon credits of a process in mind. A plastic form is indeed a green formwork that finds numerous rounds of exhaustive use over several years.
