Roof Truss Tension Rods

The axially connected truss utilizes hidden steel rods to provide tension sufficient to allow greater open spans.

Roof truss tension rods.

The more complex the truss framework is the greater quantity of these joints will be required. The same thing is true for the bridge of the truss. 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. These steel joints are needed to support the overall truss.

Steel tension rod connection. The detail on the left shows ones solution. Steel tension rods can carry in excess of 35 000 pounds of tension in large timber trusses. Tie rods are supplied with left hand and right hand threads so that they may be.

Finally the truss calculator will compute the best dimensional method to connect the pieces of the truss with steel joints and a bridge. The tension members in the web of the truss are 1 25 inch 3 2 cm diameter wrought iron rods. A boot is attached to the timber tie with bolts and shear plates transferring the load. 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.

Our in house deep hole drilling capability allows atm to incorporate this technology into its truss design and fabrication. 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. Custom fabricated steel brackets were installed at the heel joints to transfer the top chord loads into the new steel tension rods. The trusses are tensioned between the concrete floor slab and the steel roof structure.

Trusses having a more contemporary appearance may utilize steel tie rods for some members.
