T-slot plate installation

Before installing the plate onto the foundation, it is necessary to pour the anchor wells (cups) with cement mortar. At the same time, it is essential to ensure there are no external vibrations, which may be caused by nearby operating machines or other equipment. During the installation work, their operation should be temporarily suspended for 12–15 hours to prevent any negative impact on the quality of the concrete bonding.

The cast iron base may consist of different numbers of installation plates (from two to several dozen). During installation, it is necessary to consider the time required to install each plate. A rational approach to pouring the cement mortar involves filling the wells step by step as the plates are installed, thus avoiding premature setting of the mixture and additional labor and material costs.

Immediately after pouring the cups, the plate is suspended above its actual position using a crane so that the anchor holes align precisely with the wells. To prevent accidents and reduce static load on the lifting mechanisms, the plate should be temporarily rested on special support stands during anchoring. When securing the anchors, it is important to allow for a technological thread margin, as the leveling of the overall working surface of the cast iron base will be performed after the concrete fully sets.

Once the anchors are secured, the plate is lowered onto the foundation. It is essential to ensure that the anchor does not touch the bottom of the cup. Therefore, the installation procedure includes special 25 mm thick steel shims, which are placed around the perimeter of the plate and remain in place. After the cast iron plate is fixed in the cups, the transport eye bolts are unscrewed, and the next plate is installed. The concrete mixture fully sets in approximately 3 days. After this period, leveling can begin.
