There are several different types of formwork pins that are commonly used in steel frame formwork systems. These pins are essential for securing the formwork panels and ensuring the stability of the entire structure. Some of the different types of formwork pins used in steel frame formwork systems include:
1. Wedge pins: These are the most commonly used formwork pins and are designed to secure the formwork panels together. They have a wedge shape that allows them to be easily inserted and removed. Wedge pins are typically made of steel and are available in various sizes to accommodate different thicknesses of formwork panels.
2. Flathead pins: These pins have a flat head and are used to hold the formwork panels in place. They are inserted through holes in the formwork panels and secured with a nut or washer on the opposite side. Flathead pins provide a secure connection and are often used in combination with other types of pins for added stability.
3. Connecting pins: These pins are used to connect two or more formwork panels together. They typically have a threaded end that allows them to be screwed into the panels. Connecting pins are commonly used in situations where a tight and secure connection is required, such as when forming corners or curved walls.
4. Tapered pins: These pins have a tapered shape, with one end being larger than the other. They are used to align and secure formwork panels by inserting the larger end into pre-drilled holes in the panels. Tapered pins provide a tight fit and are often used in conjunction with other types of pins for added stability.
5. Snap pins: These pins have a snap-on design that allows them to be easily attached and detached from the formwork panels. They are typically made of plastic or metal and are used in situations where frequent assembly and disassembly of the formwork is required.
Overall, the different types of formwork pins used in steel frame formwork systems serve the purpose of securing the formwork panels and ensuring the stability of the entire structure. The specific type of pin used will depend on factors such as the formwork system being used, the thickness of the panels, and the desired level of stability and security.
