Connector Pins

PPI and PDQ Connector Pins are used to connect the concrete layers of sandwich walls together. Connector pins are used together with diagonal ties. The product range allows to use connector pins with various insulation thicknesses.

PPI and PDQ Connector Pins are single connectors typically used in combination with diagonal ties to restrain deformation perpendicular to the concrete layer, such as warping. The connector pins are placed along the edges of the sandwich wall element.

 Connector pins require an anchoring depth of 50 mm. The anchoring depth is ensured by installing the pin through the insulation up to the limiter in the pin. The product range covers insulation thicknesses from 80 mm to 360 mm. The minimum connector pin length is 90 mm + insulation thickness.
