The Joist end LRT is a thickened, heavy duty helical tie supplied in two lengths: 220mm and 350mm
The joist end helical Lateral Restraint Tie is designed to drive into end grain timber, side grain timber, and to all forms of masonry.
The tie can be installed from the outside of the wall into the end grain of the timber, or through the side grain of an end bearing joist into the surrounding masonry.
Ties are installed through pilot hole in brickwork or side grain wood, and directly driven into end grain wood.
70mm embedment into ingrain timber will achieve 1.0 to 2.0 kN tensile proof load in the wood and 2.5 to 3.5kN tensile proof load in the masonry.
Pilot hole diameters are typically between 5 and 6.5mm diameter dependent on density of the brick and wood.
The installed tie locks the masonry and timber together preventing further lateral movement.
