Sandwich Panel Connector – Reliable Anchoring for Precast Concrete Panels
The sandwich panel connector, also known as a forged panel anchor or butterfly plate, is a crucial element used in the production of insulated precast concrete sandwich panels. These connectors securely fasten the inner and outer concrete layers while maintaining the correct spacing and ensuring reliable load transfer across the insulation layer.
Made from high-strength forged steel, these panel anchors are designed to meet the demanding structural and thermal performance requirements of modern precast construction. The unique butterfly-shaped plate improves stability and ensures firm bonding between the concrete layers while minimizing thermal bridging.

- Butterfly Plate Design: Provides excellent concrete anchorage and shear load resistance
- Secure Multi-Layer Connection: Fixes the inner and outer concrete layers while spanning insulation
- Available in Multiple Sizes: Lengths and angles available to fit various panel thicknesses
- Used in Vertical and Horizontal Wall Panels: Ideal for large precast façade and wall systems
Applications
-
Precast concrete sandwich wall panels
-
Insulated architectural façades
-
Modular precast building systems
-
Load-bearing and non-load-bearing wall elements
-
Suitable for both factory-cast and site-erected precast panels
How It Works:
The forged panel anchor is placed during casting to link the outer concrete layer (exterior) and inner structural concrete layer (interior) of a sandwich panel, which includes insulation between them. The butterfly-shaped plate ensures the connector locks firmly into both layers, transferring loads and preventing separation while maintaining the correct spacing and insulation performance.
This anchoring system ensures:
-
Reliable shear and tensile load transfer
-
Structural integrity during handling, transportation, and erection
-
Maintained thermal performance of the insulation layer
