Steel formwork systems commonly utilize various types of formwork ties to secure the formwork panels together and maintain the formwork structure's stability and strength.
1. The wedge tie, which is the most commonly employed formwork tie in steel formwork, involves inserting a wedge-shaped metal piece into a hole in the formwork panel. By tightening the wedge, a robust connection is established, firmly holding the panels in place.
2. The pin and wedge tie is another type of tie that consists of a pin and a wedge. The pin is inserted into a hole in the formwork panel, and subsequently, the wedge is driven into the pin, creating a tight connection.
3. The wing nut and tie rod tie system employs a wing nut and a tie rod to secure the formwork panels together. The tie rod is threaded through the panels and secured by wing nuts on both sides. This tie system allows for the convenient removal and reassembly of the formwork.
4. A coil tie is utilized when the formwork panels need to be fastened to the steel reinforcement bars. The tie is threaded through the formwork panel and then wrapped around the reinforcement bar, establishing a secure connection.
5. Flat ties are employed to tightly connect formwork panels in situations where a secure fit is required. These ties are flat metal strips inserted into holes in the formwork panels and then tightened.
These examples illustrate only a few of the various formwork ties employed in steel formwork systems. The choice of tie depends on factors such as the specific formwork design, load requirements, and ease of installation and removal. It is essential to select the appropriate tie system to ensure the stability and safety of the formwork structure.
There are several different types of formwork ties that are commonly used in steel formwork systems. These ties are essential for holding the formwork panels together and ensuring the stability and strength of the formwork structure.
1. Wedge Tie: This is the most common type of formwork tie used in steel formwork. It consists of a wedge-shaped metal piece that is inserted into a hole in the formwork panel. The wedge is then tightened, creating a strong connection and holding the panels in place.
2. Pin and Wedge Tie: This type of tie consists of a pin and a wedge. The pin is inserted into a hole in the formwork panel and then the wedge is driven into the pin, creating a tight connection.
3. Wing Nut and Tie Rod: This tie system uses a wing nut and a tie rod to hold the formwork panels together. The tie rod is threaded through the panels and secured with a wing nut on each side. This type of tie allows for easy removal and reassembly of the formwork.
4. Coil Tie: A coil tie is a type of tie that is used when the formwork panels need to be secured to the steel reinforcement bars. The tie is threaded through the formwork panel and then wrapped around the reinforcement bar, creating a secure connection.
5. Flat Tie: Flat ties are used to connect the formwork panels in situations where the panels need to be secured tightly against each other. These ties are flat metal strips that are inserted into holes in the formwork panels and then tightened.
These are just a few examples of the different types of formwork ties used in steel formwork systems. The choice of tie will depend on factors such as the specific formwork design, the load requirements, and the ease of installation and removal. It is important to select the appropriate tie system to ensure the stability and safety of the formwork structure.
Some of the different types of formwork ties used in steel formwork include snap ties, wedge ties, coil ties, and flat ties. These ties are used to secure the formwork panels together and provide stability during the concrete pouring process.
