What is formwork system and what makes a good formwork？
The construction formwork system is a formwork system used to form various elements of reinforced concrete structures (walls, columns, beams, shears, etc.). Formwork systems are specially designed according to the shapes of the structures and are used in the construction process along with processes such as placing the formwork, pouring the concrete, hardening the concrete and removing the formwork.
Formwork systems can be produced from wood, steel, aluminum or plastic materials and each material has different advantages. For example, wood formwork systems are inexpensive and can reduce labor costs, but are limited in durability. While aluminum molds are preferred because they are light and easily transported, steel molds are more durable and long-lasting.
Construction formwork systems help complete construction projects faster and more efficiently. In addition, formwork systems are environmentally friendly by using less material and producing less waste during construction.
What Makes a Good Formwork?
In order to obtain the results you desire, it is imperative that you choose the best and most reliable formwork. Although sound formwork systems differ by material or the build-ing elements they support, they share specific qualities that make them worthy of your time and investment.
Here are the qualities that your preferred system should possess:
1. Exceptional load capacity
The formwork system should be strong enough to withstand any dead (e.g. the weight of the concrete structure itself and other permanent loads) and live (e.g. the weight of building occupants, vehicle traffic, equipment, and other temporary elements) loads.
2. Outstanding shape retention capability
The formwork should be constructed rigidly and supported correctly by props and braces so it can retain its shape.
3. Leak-proof joints
The joints should be tightly sealed to prevent any cement leakage
4. Does not damage the concrete
If the formwork is removable, it should be constructed in such a way that the various parts can be removed easily without damaging the concrete.
5. Made from reusable material
A formwork system that can be repaired and reused multiple times, such as one made of steel or aluminum, will help you minimize your costs and maximize savings. In addition, it will be friendlier to the environment
6. Lightweight
Formworks made of lightweight materials are easier and faster to transport and assemble, allowing you to save on time and labor.
7. Free from warping and distortion
To ensure optimum reliability, the formwork should not warp or become distorted when exposed to the elements.
