Tie connectors for large panel construction

Intended use

Tie connectors for large panel construction are intended for connecting the internal and external wythes of insulated sandwich wall panels.

Design

The tie connector for large panel construction comprises the following elements:

For the use in a bearing panel:
  • BFRP bar with a uniform sand coating,
  • Plastic restrainer,
  • Stainless steel collar.
For the use in a non-bearing panel:
  • BFRP bar with a uniform sand coating,
  • Plastic restrainer.
Tie connectors with a restrainer installed at 45 - designed to transfer vertical loads from an external concrete wythe and thermal insulation to a reinforced wythe of a panel.

Tie connectors with a restrainer installed at 90 - designed for fixing reinforced concrete wythes and thermal insulation against each other as well as for taking compressive and tensile loads caused by wind and other impacts acting perpendicularly to a facade surface.
  • Tie connectors with a restrainer installed at 45
  • Tie connectors with a restrainer installed at 45
  • Tie connectors with a restrainer installed at 90
  • Tie connectors with a restrainer installed at 90
