Movement During Seismic Event
The VertiBrace ensures that interior partition walls will not be crushed or pulled apart. It will prevent interior glazing from popping out of the aluminium pockets and support safe egress. More routinely, once the floors are loaded and deflect with the weight, there is no downward pressure experienced by the partition.
- A lining sleeve inside the cylinder reduces noise associated with relative movement of two metal surfaces. This greatly reduces footfall vibrations from transferring down through the partition walls, therefore VertiBrace creates an improved acoustic separation between upper and lower levels.
- When installed, the VertiBrace allows for +/- 25mm deflection. The amount of movement can be increased by extending the stem where required.
- The lateral strength has been tested up to 15mm of uplift.
- The VertiBrace is suitable for ceiling height and full height partition walls in commercial interiors.
The VertiBrace has been extensively tested to exceed the New Zealand building Code using sound engineering principles. The performance and capacity of all brackets has been quantified by extensive physical testing.
The VertiBrace is a partition wall bracket comprising a cylinder that connects to the upper surface of a wall and a stem that connects to the building structure above. The stem is designed to move within the cylinder along the longitudinal axis of the body. The VertiBrace is installed in the neutral position. The neutral position is held by a cable tie that is cut once it’s installed, and once free, the VertiBrace will allow for a nominal 25mm up and 25mm downward movement. It completely removes the need for deflection head-track. For larger movement allowance, the stem can be extended.
Most commercial buildings need their interior partitions to allow for some vertical movement.
Vertical actions on partition walls may be the result of frame deflections caused by inter-storey drift. These actions can be experienced
during seismic or wind loading events. Another contributor to vertical movement are live and/or dead loads on the level above.
