Floor Truss Bridging

The 2x6 serves the same purpose as bridging in a standard floor distributing concentrated loads over a wider area.

Floor truss bridging.

Truss two runs for longer trusses. Floor joist bridging vs blocking i like laying 1 1 8 super flat easy to pound t g together dropping a 2x6 from a floor above doesn t put a hole in it. Ansi tpi 1 2002 includes information in the commentary to section 7 5 2 4 regarding the use of strongback bridging to reduce the effects of differential deflection in floor trusses. Floor joist bridging is critical to the structural strength of a floor as shown in figure 1.

If span is greater than 8 install on 2x8 or larger joists. Even if your floor already has a row of bridging running down the center you can stiffen it substantially by adding two more rows. Strongback bridging system dampens floor vibrations. Floor truss is designed and produced to your specific needs and delivers reliable performance.

The load sharing element is typically considered to be the floor diaphragm. If span is greater than 16 use more than one pair. 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. All open joist truss layout plans include strongback bridging specification and location.

Underneath 2x6 strongbacks laid on edge should run continuously through the webs of all the trusses at 10 ft. Details to minimize the chance of future squeaks and to help secure the new floor sheath ing start by spreading a generous amount of construction adhesive over the old planks. I ve always used a lift for upper floors though. Floor truss open concept allow the installation of strongback bridging which actively contribute to reduce floor vibration.

Support floor joists with a depth to thickness ratio of six or more with bridging at intervals not exceeding 8. Bottom of the floor joists instead of or in addition to being installed on top. The catch of course is that the bouncy floor joists must be accessible from below. Lay the new sheets perpendicular to the floor joists and orient panel ends over joists.

Intervals one run for a 20 ft. U section bridge under hung floor beam generally for shorter spans. Tension bridging works only in tension so must be used in cross pairs. Pony or pratt truss bridges are half through truss bridges no overhead members box or full through truss overhead members two types of pony truss configurations.

The addition of this important structural component allow the individual.
