Formwork pins are essential components in steel frame formwork systems, serving to secure formwork panels and ensure stability while pouring concrete. Here are several types of formwork pins commonly utilized:
1. Wedge pins: The most widespread formwork pins, they possess a steel composition with a wedge-shaped end. By inserting the wedge into the formwork panel slot and using a hammer, the pin is driven into place. This wedging action tightly secures the formwork panels, effectively preventing movement during concrete pouring.
2. Straight pins: Similar to wedge pins, straight pins are also made of steel, but with a cylindrical shape. These pins are inserted into pre-drilled holes in the formwork panels and secured using a hammer. Straight pins are suitable when wedge pins cannot be easily inserted or when additional reinforcement is required.
3. Snap ties: This formwork pin type consists of a metal rod with a button-like head. The rod is inserted through the formwork panels, and the head is snapped into place, firmly securing the panels together. Snap ties are commonly employed in formwork systems that necessitate quick assembly and disassembly.
4. Coil ties: Coil ties serve as another formwork pin option for connecting formwork panels. They feature a metal rod with a spiral coil at one end. The coil is inserted into pre-drilled holes in the formwork panels, and the rod is twisted to tightly secure the panels. Coil ties provide a robust and secure connection between the formwork panels.
5. Flat ties: Utilized specifically in wall formwork systems, flat ties secure formwork panels in a flat orientation. These pins consist of a metal rod with a flat plate-like head. By inserting the rod through the formwork panels and twisting the head, the panels are securely fastened together.
In summary, the diverse range of formwork pins employed in steel frame formwork systems offers various options to ensure secure and stable connections between formwork panels during concrete pouring.
There are several different types of formwork pins that are commonly used with steel frame formwork systems. These pins are used to secure the formwork panels and ensure stability during the concrete pouring process.
1. Wedge pins: These are the most commonly used formwork pins. They are made of steel and have a wedge shape at one end. The wedge is inserted into the slot on the formwork panel, and the pin is then driven into place using a hammer. The wedge shape helps to secure the formwork panels tightly, preventing any movement during the concrete pouring process.
2. Straight pins: Straight pins are also made of steel and are used in a similar way as wedge pins. However, instead of a wedge shape, these pins have a straight, cylindrical shape. They are inserted into pre-drilled holes in the formwork panels and secured in place using a hammer. Straight pins are often used in situations where a wedge pin cannot be easily inserted or where additional reinforcement is needed.
3. Snap ties: These are a type of formwork pin that consists of a metal rod with a button-like head at one end. The rod is inserted through the formwork panels, and the head is then snapped into place, securing the panels together. Snap ties are commonly used in formwork systems where quick assembly and disassembly are required.
4. Coil ties: Coil ties are another type of formwork pin that are used to secure formwork panels together. They consist of a metal rod with a spiral coil at one end. The coil is inserted into pre-drilled holes in the formwork panels, and the rod is then twisted to secure the panels tightly. Coil ties provide a strong and secure connection between the formwork panels.
5. Flat ties: Flat ties are formwork pins that are used to secure formwork panels together in a flat orientation. They consist of a metal rod with a flat plate-like head at one end. The rod is inserted through the formwork panels, and the head is then twisted to secure the panels tightly. Flat ties are commonly used in wall formwork systems.
Overall, the different types of formwork pins used with steel frame formwork systems provide a variety of options to ensure that the formwork panels are securely connected and stable during the concrete pouring process.
There are several types of formwork pins commonly used with steel frame formwork systems, including flat head pins, wedge pins, pin and wedge systems, and snap tie pins. Each type serves a specific purpose in securely connecting and aligning the formwork panels, ensuring stability and accuracy during the concrete pouring process.
