Installation

Lay-On Gables are an opportunity for component manufacturers.

Open web trusses are the ideal match with a sprinkler system, maximizing use of space and making installation easy.

NFC Executive Director Chris Tatge and SBCA staff member Jim Vogt demonstrated on the BCMC show floor just how quickly a structure comes together with wall panels.

When Jim’s Apple Barn, the largest candy store in Minnesota, wanted to expand by way of adding a confection-filled planetarium to the end of a blazing yellow barn already bursting with sweets, it had a difficult time finding a truss company willing to take on the project. “We were the only ones that said yes,” recalled Trevor Ebinger, a member of the Manion Lumber & Truss sales staff. “It was quite an undertaking.”

When Mandere Construction couldn’t get the trusses it needed to frame its projects, owner John Mandere went looking for the best truss folks he could find—and hired them

We recently received bids on a school project, which referenced UL P523. This assembly used light-gauge steel trusses. We noted on the drawing that we could accept an alternate design using wood trusses in lieu of light-gauge steel framing, if the alternate design could meet the fire ratings.

Some building designers believe that gable end webs need to be L-braced to 90% of the web length, which sounds fine. However, they spec that scissors gable end webs need to be braced to 100% of the web length. That means that in the field they are notching the braces to fit around top and bottom chords – you can imagine how difficult that can be. Is that necessary or even the intent of the web L-bracing?

If trusses blew down from insufficient temporary bracing and the contractor put them back up without the knowledge of the truss manufacturer and gave the truss manufacturer a letter stating that the trusses were okay, is that sufficient? Do you know of any truss manufacturer who would accept this?

I was wondering if you have any information or anecdotes relating to the deflection performance of long span scissors trusses? We recently sold a job with 70 ft. long scissors trusses. The customer is in the process of installing the trusses and doesn't like the deflections he is seeing. To make matters worse, the scissors trusses are framing into a valley set (which we provided) that is erected on 35 ft. Howe trusses. The Howe trusses are exhibiting very little deflection. Any ideas?

I am remodeling a 16-year-old ranch style home. The roof consists of 4/12 26 ft. span trusses, 24 in. O.C., over 2x4 stud walls. What is the recommended means of affixing the top plate of new interior partitions to provide the lateral support needed for the partition? Also, I want to hang a soffit above and overhanging the new kitchen cabinets (recessed lighting placed within). What is the recommended means of attaching the soffit to the underside of the trusses so as not to interfere with the designed movement of the trusses under the variable live load experienced (snow load)?
