DEFLOK® range.
Seismic actions come in all directions and although as an industry we mostly account for horizontal deflections, in some instances vertical deflection needs to be taken into consideration.
Vertical deflection has traditionally been taken up in the head track of a wall system, where a deflection head track slips over the steel studs but is not connected to the studs or plasterboard.
This allows the head track to move up and down relative to the rest of the wall, allowing for +/- 20mm of vertical deflection, which is arguably more than enough in most cases.
Traditionally vertical movement from the floor or structure above is accounted for in this way, stopping damage occurring to the top of the wall.
Certain projects require more vertical deflection allowance than a deflection head track is capable of providing for. The reasons for vertical action include high wind or snow loading on purlin roofs, seismic conditions in the area the building is situated or where a project has been engineered to a high vertical deflection requirement.
TRACKLOK® Flat has provided an simple and robust way to deal with vertical deflection issues, by bracing walls against each other and not connecting to the structure over, allowing for unlimited vertical deflection. Since 2017, our technical design team have been working with our engineering team and industry professionals to develop the DEFLOK® vertical deflection solution.
The DEFLOK® solution is an elegant and proven way of accounting for +/– 35mm of vertical movement.
DEFLOK® has been physically tested to have 241 KGF of capacity through the full range of the unit’s vertical movement. DEFLOK® can take all lateral loading the industry has come to expect from the TRACKLOK® range of wall braces, while operating at the full extension of the brace.
DEFLOK® has also been designed as a sealed unit, so there is no way the brace can come apart at maximum deflection, this is critical when dealing with high deflection projects.
DEFLOK® also employs spring technology to hold the brace in the neutral position, making installation simple, while also bringing the unit back to neutral after a vertical movement has occurred.
With the deserved reputation as the leader in commercial wall and ceiling bracing worldwide, you can specify DEFLOK® with confidence.
