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.
- BFRP bar with a uniform sand coating,
- Plastic restrainer.
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.
Marking
| BPA 300-60-6-P-90, where BPA – BFRP bar; 300 – tie connector length, mm; 60 – distance from the end of the tie connector to the plastic restrainer, mm; 6 – bar diameter, mm; P – bar sand coating; 90 – restrainer installation angle, angle degree. | BPA-V 420-90-6-P-45, where: BPA – BFRP bar; V – tie connector with stainless steel collar; 420 – tie connector length, mm; 90 – distance from the end of the tie connector to the plastic restrainer, mm; 6 – bar diameter, mm; P – bar sand coating; 45 – restrainer installation angle, angle degree. |
