Abstract

A concrete sandwich panel (10) is provided with a first dry-cast hollowcore concrete layer (12) having pre-stressing strands (24), and a second concrete layer (14), and an insulation layer (16)sandwiched therebetween. The insulation layer (16) includes pre- formed holes (26). A tool is used to form holes in the first concrete layer (12) aligned with the insulation holes (26). Adhesive (40) is injected into the concrete holes (28). The adhesive (40), when cured, locks the connector (18) in the hollowcore concrete layer (14). The upper concrete layer (12) is cast over the insulation layer (16) so as to embed the upper ends of the connectors (18). The plasticity of the upper concrete layer (12), which may result from vibration energy input to low-slump concrete, allows the concrete to consolidate around the upper ends of the connectors (18). When the concrete layers (12, 14) cure, the connectors tie the layers together to preclude excessive shear displacement between the concrete.
