PVL^® Connecting Loops are single-wire loops used for connecting precast wall panels to one another or to a column. PVL^® Connecting Loops simplify the wall installation process, as they only require the removal of a protecting tape and bending of the loop out from the box.

Prior to the casting of the elements, wire loop boxes are installed onto the formwork at the necessary spacing to bear shear loads. Once the formwork is removed, the protective tape covering the loops can be taken off, and the loops can be bent open using a hammer or a pin. The wall panels are then installed and supported as per the construction plans. A vertical rebar is inserted through the loops, ensuring structural integrity. The horizontal position of the loops is checked to ensure proper alignment. Finally, after the completion of the formwork, concrete grout is poured or pumped into the joint to complete the installation.

PVL^® Connecting Loops are available in standard wire lengths of 60 mm, 80 mm, 100 mm, 120 mm, and 140 mm, suitable to joint depths ranging from 80 mm to 140 mm.
