The rod is inserted through holes in the formwork panels, and the plate is attached to secure the panels. Snap ties are quick and easy to install and can be easily removed after the concrete cures. 2. Tie rods are long steel rods with threading on both ends. They are used to connect the formwork panels by passing them through the panel holes and securing them with nuts and washers. Tie rods provide robust and stable connections that can withstand high pressure and loads. 3. She-bolts are similar to tie rods but have a fixed female thread at one end. Used in combination with wing nuts and washers, she-bolts hold the formwork panels together. They are particularly useful when tie rods need to be quickly and easily removed. 4. Flat ties are flat-shaped steel wires or bars. They are inserted through the formwork panel holes and secured with cones or washers. Flat ties establish a secure connection between the panels and are commonly used in large-scale construction projects. 5. Coil ties are flexible steel wires coiled at one end and threaded at the other. They are inserted through the formwork panel holes and secured with cones or washers. Coil ties are especially advantageous in curved or irregular-shaped structures. 6. Combination ties merge the characteristics of snap ties and tie rods. They consist of a metal rod with a flat plate at one end and a threaded end at the other. Combination ties are versatile and can be utilized in diverse formwork applications. Choosing the appropriate tie type is crucial for steel formwork construction projects. Factors such as the structure's size and shape, required load-bearing capacity, and ease of installation and removal influence the tie selection.
