Tji Floor Joist Bridging

Bridging allows each joist to share weight with its neighbors and can cut deflection how much the joists flex by half.

Tji floor joist bridging.

Install with two 6d common nails per end. Tji joist benefits easily drilled and cut for plumbing and ductwork. Unless you specify the 360 or 560 series tji joists and the span is not excessive open to debate or discussion the slenderness ratio for the 110 210 or 230 series is not much. Even if your floor already has a row of bridging running down the center you can stiffen it substantially by adding two more rows.

Featuring trus joist tji joists for floor and roof applications uniform and predictable lightweight for fast installation resource efficient resists bowing twisting and shrinking significantly reduces callbacks available in long. I ve been told for many years that the typical tji system does not require bridging or blocking because of their structural integrity or similar expression. However bridging is one of the least effective solutions for bouncy floors. The catch of course is that the bouncy floor joists must be accessible from below.

Our code report icc esr 1153 specifically states that bridging is not required for floor and roof tji joist applications. Tji 110 tji 210 tji 230 tji 360 tji 560 and tji 560d joists. Proper bridging distributes the load on the floor to other joists and over time prevents floors from sagging and squeaking do to floor joists twisting and warping. Consequently they do not see any significant benefit from bridging.

Trus joist tji joists are made with no observable twist and have minimal material variation between joists within any joist series depth. Tji joists are lightweight and come in long lengths which makes them faster and easier to install than traditional framing and saves you both time and money. The most obvious solution is to add a beam supported by posts under the floor joists. Thd sku 205173.

Floor joist bridging is critical to the structural strength of a floor as shown in figure 1. Simpson strong tie tension bridging galvanized steel the ltb s are used in floor systems to resist the overturning of floor joists and features a staggered nail pattern.
