FLOORLOCK for Optimizing and Increased Floor Load Sharing
FLOORLOCK bracing is engineered to spread heavy loads over the whole floor area reducing floor deflection and bounce.
I-Joists are susceptible to Lateral Torsional Buckling (LTB) Failure
The slender nature of wood I-joists is desirable for flexural resistance but comes at the price of lateral instability as they become susceptible to lateral torsional buckling (LTB) failure. When an I-Joist floor system is not restrained against lateral and angular displacements, it develops a tendency to undergo lateral torsional buckling when it is bent about its major axis.
Without Floorlock: The I-Joist flange carries the bending moments whilst the I-Joist web collects the sheer force. The sheer force is then transferred to the end of the I-Joist on the wall and to the foundation.
Lateral Instability Problems
- Bucking of web under heavy point loads
- Knifing through Flange
- I-Joist Roll Over from Racking forces
- Floor softness and bounce
- Deflection of floor resulting in cracking tiles
- Squeaky floors
- Vibration and rattling furniture
With Floorlock: The Floorlock bracing system disperses the bending moments and the sheer force across multiple I-Joists, providing superior load bearing capacity over the entire floor.
Improved Performance
- Sheer forces are spread over the whole floor - not just at the ends on the wall
- Improved floor performance under heavy point loads
- I-Joist Flance is cradled and supported from both sides
- Reduces the risk of roll over of I-Joists during high winds and earthquakes
- Lateral support over the whole floor
- Floors are stiffer, stronger and safer
