Helifix BowTie and BowTie HD
The Helifix BowTie is used only for end joist applications. It utilises the 8mm Helibar material in varying lengths and is able to connect either directly into the end grain of timber, or by installing at an angle to either side of the joist to create a cross pinning effect, see plan view below.The Helifix BowTie HD is used to assist the lateral restraint of masonry walls by connecting, or reconnecting floor joists, ceiling joists and/or roof members back to masonry walls.
It utilises a 12mm heavily profiled stainless steel rod with a self-drilling tip and is able to connect into several timber members through the side grain of the timbers. The Helifix BowTie HD can also be tested for pullout resistance.Helifix BowTie and Bowtie HD installation normally takes place from the outside of the building. Some adjacent floorboards are lifted internally, allowing good visibility in the floor void to ensure that any services are not damaged.
When the Helifix BowTie installation is complete, floorboards are refixed securely. This is to ensure that the diaphragm action of the floor is fully utilised.
With either of the applications of the Helifix BowTie and BowTie HD, the conventional use of strapping, bolting or pattress plates is no longer necessary.
