The anchoring device is used to connect the rail steel supports to concrete foundations. Consisting of a bolt, washer, nut and adhesive, the standard anchor bolts are installed by drilling holes in the concrete deck, mixing the resin before filling the hole and inserting the anchor bolt. The mixed resin works as an adhesive, suspending the bolt in place until it cures to complete the process. Anchor types are conditional on a range of varying factors including, but not limited to civil engineering constraints, performance or installation practices, and as such are provided in a range of steel grades and shapes and with varying adhesive products.
