Coil ties are an essential component in concrete forming systems. They are used to hold the formwork together while concrete is being poured, ensuring the structure maintains its shape. They provide tensile strength and stability to the poured concrete.
Begin by setting up the concrete formwork as per the project specifications. Make sure the panels are positioned correctly and aligned with the desired dimensions.
Use a measuring tape to mark the points where the coil ties will be installed. Typically, these should be spaced evenly and in accordance with the engineering guidelines.
Using a drill and suitable drill bit, drill holes at the marked points through the form panels. Ensure that the holes align with each other across opposing walls of the formwork.
Insert the coil ties through the drilled holes. The spiral feature should face towards the outside of the formwork. This will help to grip the concrete as it cures and adds strength to the structure.
Once the coil ties are in place, secure them using the appropriate forming accessories (such as nuts and washers) on either side of the form panels. Ensure that these are tightly fastened to maintain stability.
Before pouring the concrete, check the alignment of the formwork using a level. Adjust the panels as necessary to ensure they are straight and properly positioned.
Once everything is aligned and secured, you are ready to pour the concrete. Carefully pour it into the form, ensuring even distribution to avoid any displacement of the panels.
After the concrete has adequately cured (typically 24 to 48 hours), you can safely remove the formwork. Carefully detach the coil ties using the appropriate tools, making sure not to damage the newly formed concrete.
Using coil ties properly will ensure the structural integrity of your concrete forms. Follow these steps closely for a successful pour and durable outcome.
