HK panel ties for vertical pour (VP) applications are specifically designed for use in cast-in-place and modular precast applications. They provide a fast, efficient method of insulating concrete structures without compromising the low-maintenance/high durability of concrete walls.
Each sheet of insulation should be marked on one side with dots on 305mm (12-inch) centers, indicating where ties would normally be inserted into the foam.
The HK VP tie is designed to work with two clips per tie to hold the foam in place during casting. The clips fit into recessed areas on the tie.
The HK VP ties may be used in most modular precast and cast-in-place applications where the following conditions apply:
Repeat the above steps for each tie.
Ties should be no closer than 100mm (4″) and no further than 200mm (8″) from the edge of the foam. In these cases, you may need to either shift ties away from the panel edges or openings or add extra ties so this spacing is maintained.
While placing the concrete inside the forms, place the concrete on either side of the foam as equally as possible. Make certain the concrete level on one side does not vary from the level on the opposite side by more than 18 inches.
