Main Functions of Formwork
Reinforced concrete formwork generally consists of two parts. The first part is used as the sections obtained on the surfaces of reinforced concrete elements. The second part is the scaffolding that holds the formwork at the desired heights and also supports the concrete inside until it sets. The materials used at this point are wood, metal, and plastic. According to construction methods and techniques, there are classic systems, which are used in low-rise buildings. For covered surfaces, wood is used, and metal pipes are used for scaffolding parts. Steel panel and modular systems are also used multiple times in constructions that are not very high-rise. Climbing systems are mostly used for wall formwork, and panels of 75*250 cm are used in structures to be built upwards. Formwork is generally used effectively to give the necessary dimensions and shapes to reinforced concrete elements. They are used to carry the fresh concrete weights, fresh concrete pressures, and additional loads that arise during concrete pouring. The formwork must also be resistant to the impact and vibration effects that may occur during concrete pouring. It is also useful to use them as working and transfer decks in all necessary situations.
What to Know About Formwork Costs
Today, as a result of all developments in concrete technologies, building elements can be made more slender and detailed. In these cases, the costs of formwork for processed unit concrete will start to increase. In formwork costs, the labor cost of formwork is approximately three times the cost of the formwork material. Since the costs of concrete and all reinforcement are not changed much, an economy in rough construction costs can be achieved by reducing formwork costs. For these reasons, instead of the classic formwork systems where all formwork boards, planks, props, nails, and all connecting elements are assembled on-site according to the dimensions of the elements to be formworked and then dismantled, they should be replaced. In these formwork systems, all formwork elements are manufactured industrially in specific shapes and standards and are used on-site according to a work program, and the formwork surfaces, support structures, and auxiliary elements are formed.
