Roof Truss Tension Rods

That load needs to be transferred from the rod to the timber truss.

Roof truss tension rods.

The more complex the truss framework is the greater quantity of these joints will be required. Our in house deep hole drilling capability allows atm to incorporate this technology into its truss design and fabrication. The tension members in the web of the truss are 1 25 inch 3 2 cm diameter wrought iron rods. The trusses are tensioned between the concrete floor slab and the steel roof structure.

Swc can source these rods in a variety of diameters lengths and materials along with appropriately sized clevises to create a clean pinned connection to attachment points. Trusses having a more contemporary appearance may utilize steel tie rods for some members. Oct 29 2015 this project involves tied rafter trusses tie rod trusses multiple angle steel tie rod truss connections wood and steel truss system fin plate and pin connections and hinge and pin connections. The common news media comment about a truss roof or floor having collapsed suddenly without.

Custom fabricated steel brackets were installed at the heel joints to transfer the top chord loads into the new steel tension rods. The detail on the left shows ones solution. These steel joints are needed to support the overall truss. Steel tension rod connection.

The main feature of this repair was the installation of post tensioned steel rods designed to relieve the truss bottom chords of overstress due to code prescribed snow loads. The same thing is true for the bridge of the truss. Tie rods are supplied with left hand and right hand threads so that they may be. A boot is attached to the timber tie with bolts and shear plates transferring the load.

The system pretension loading and sizing of the tension rod is determined from the thermal load dead load creep seismic and wind loading conditions specific to the supporting structure.
