Are You Making Correct Substitutions and Placements When Upsizing Connectors?

Glenn Traylor

Sometimes it is necessary to deviate from the truss design drawing and use a different connector. This may happen when a specific size connector is not available or when the original connector has been removed. Per ANSI/TPI 1 Section 3.6.3, a metal connector can be substituted if the new...

The Last Word: The Current State of Robotics

Joe Kannapell

I’ve been covering the industry’s evolution toward robotics, but I’d like to stop for a minute and recall the days of corrugated fasteners. These clever clips proved themselves whenever trusses were flipped or ejected. Now, perhaps ironically, they still have a role to play...

The Development of the Truss Plate, Part V: Frenetic First Get-Together

Joe Kannapell

Twelve competitors faced one another for the first time—but only because they had to. Each of their fledgling plate businesses was threatened by a July 31 deadline from the Federal Housing Administration (FHA), and they had less than three weeks to put together a design criterion for...

Why Do I Need the Software Polygons?

Glenn Traylor

When completing an in-house inspection, a critical plate inspection is required for each truss inspected. This requirement is from ANSI/TPI 1–2014. Specifically, per section 3.7.1: No less than one critical joint per Truss selected for inspection, on average across all operational...

Understanding Plate Tooth Count and Placement

Russell Tangren, PE

Imagine a third-party truss inspector is in the yard checking truss plates as part of quality control. The plate placement diagram indicates the web needs twenty-five teeth; however, the inspector counts twenty. Even though the shop positioned the plates as designed, is the plate placement...

The Last Word: The Last Word on Automated Material Handling

Joe Kannapell

With automated saws and auto-jigging tables, what remains is automated material handling, and that’s what we find at Builders FirstSource’s (BFS) Austin plant. House of Design’s (HoD) robotic roof line there extends the floor truss pre-plating methodology found at their Atlanta...

The Development of the Truss Plate, Part IV: Competition Intensifies

Joe Kannapell

After Cal Jureit’s impressive debut at the 1958 NAHB Show, lumberyards and builders across America were anxious to start trussing, but they encountered several obstacles. Their deluge of inquiries couldn’t all be answered, and most were far away from the South Florida source of...

Are You Removing the Connectors Carefully When Replacing Them?

Glenn Traylor

Face the facts—occasionally, it is necessary to replace connectors. It’s part of the manufacturing process. In my May 2016 article, Is There a Reduction For Plating in a Previously Plated Area?, we discuss the limitations and considerations of removing a plate, including upsizing the...

The Last Word: The Last Word on Pre-Plating

Joe Kannapell

Just as Trussmatic brought back hydraulic plate pressing, House of Design has resurrected pre-plating. Both practices proved themselves in the early days of our industry, but both required disciplined shop floor management, and each had limitations. [For all images, See PDF or View in Full...

The Development of the Truss Plate, Part III: The Ingenuity of Carol Sanford and Cal Jureit

Joe Kannapell

Carol Sanford’s invention didn’t equal Cal Jureit’s, but he made up for it with his head start and his aggressive marketing. Sanford had filed for his patent in March 1954, two years ahead of Jureit’s September 1956 filing, and had a plate design that was relatively...
