ABOUT ABC ARMLOCK
The ABC Armlock is Patented Device No.GB2399832, all Design
Rights Reserved and are manufactured, sold and distributed under
licence.
HOW IT WORKS
Used as a retrofitted system to provide lateral
restraint to walls, the ABC Armlock is fixed to the external wall with a
suitable anchor, such as the Cintec system, and the Armlock is simply secured
to the side of the two adjacent joists with coach screws or bolts. The ABC
Armlock has been load tested to 10kN tensile load without any observed affects
upon the device.
No matter what spacing the joists are set at,
up to a maximum of 500mm, the ABC Armlock will fit.
Additionally, the joist fixing is set back from
the end of the joist, thereby avoiding any soft timber which may exist adjacent
to the wall.
This creates a mechanical connection with the
floor plate. The floor coverings, such as plywood, chipboard or other boarding,
must be screwed to the joists. Having done this the floor acts as a diaphram
and provides restraint to the wall. A qualified structural engineer should be
consulted in all cases of structural defects.
