The simplest way to become familiar with how the Stavebolt has been utilized to date in post and beam, timber frame and truss work is to visit the PROJECTS section of this web site, which is summarized briefly below.

The Collingwood Stavehouse and the Midhurst Stavebarn projects are basic post and beam applications, which lend themselves to repetitive uses of the device. The Log Home at Midhurst demonstrates how the device can be married with traditional log work where post and beam and heavy timber trussing is also part of the package. The Essa Homes Project illustrates some of the more complicated joinery associated with prow posts and multiple beam-to-post connections, etc, while the Winterwood Project shows heavy truss construction with large logs.

Our Home Page photo shows a timber truss assembled with extensive Stavebolt hardware. These trusses were designed for installation on a stick-framed wall system with large glass openings. The device was used at the high-tension locations, including the slope-cut ends of the lower chord and at the bottom of the kingpost. It was also used at both ends of the hammer post and at the inboard ends of the hammer beams.

The following CAD drawing illustrates many of the ways in which the Stavebolt hardware has been or may be applied to log and timber framing and truss construction. Whether installed in dimensional timber or round logs, the applications are basically similar.

Typical Truss Applications

  1. Ends of lower chord or tie beam: Here the tie beam is lightly housed or dapped into the lower face of the upper truss chord to transfer shear loads while the Stavebolt handles the high tension loading.

  2. Bottom of Kingpost: A typical post to beam (tension) connection. To help resist twisting of the kingpost and to provide some shear value to the connection, the post-end can be lightly housed or dapped into the top edge of the tie beam.

  3. Top of Kingpost: An effective way to attach a ridge pole or beam to the top end of a truss post while providing defined resistance to counteract uplift forces. Note that the through-bolting from the truss principals can be run through the centre of the Stavebolt device. A 3 or 4-pin Stavebolt could be used at this apex connection to provide multiple stitch bolt passages for the crossing hardware.

  4. Compression Strut: Although this member is normally exposed to compression loading, there are times when some tension capacity may be desirable. When the installation of a roof purlin coincides with the location of the strut or where substantial reverse loading might occur, the connector may be used to advantage. In such cases, the smaller Stavebolt model may provide ample performance.

  5. Hardware Crossings: Aside from the apex of the truss mentioned above, other typical hardware crossing areas may frequently be tie-beam at its meeting with the hammer post illustrates the crossing of the 5/8" tie bolt hardware of a small Stavebolt (installed in the hammer beam) through the body of the standard unit, housed in the end of the collar tie.

  6. Post through Wall Plate to Truss: The wall posts, shown on both sides of the structure, demonstrate a typical method of connecting post to wall plate, then continuing through the truss member to produce a very effective tie with a long bolt or threaded rod. This technique may be particularly useful in hurricane zones.

  7. Post to Foundation: Where uplift forces exist, it is a simple matter to continue the foundation anchor bolting directly into the bottom end of the wall post. This can be accomplished by threading the Stavebolt over the extended anchor bolt then lowering the post (or pre-assembled bent) over the device, followed by the insertion of the stitch bolts or pins.

  8. Beam to Post to Beam: Where a single pair of beams must meet intermediate support columns or posts, the Stavebolt may be utilized to tie the pair together through the post, as per the example at the bottom centre of the CAD drawing.

  9. Multiple Beam to Post to Beam: Where more than two beams must meet a support post at the same elevation, the stacking of the connecting pairs of Stavebolt hardware (connecting opposing beam ends) can be offset to accommodate the crossing of the 3/4" or 5/8" tension bolts (or all-thread) passing through the post. See sample at CAD centre.

  10. Other Hardware: The CAD drawing also mentions such items as split rings, shear plates and shear pins, in some connection area. These hidden steel devices have been utilized in heavy framing for almost a century and are still available. Many of these hidden devices are well suited for use with the Stavebolt. Refer to the Wood Reference Handbook or the Wood Design Manual published by the Canadian Wood Council, for a complete overview. See photo & notes re the 4" Split ring in the INSTALLATION section of this web site.

  11. Other Carpentry & Framing: In some situations such as where a cluster of beams meet the sides of a load bearing column, it may be impractical to reduce the vertical component to provide the necessary housing or dap to carry the beam loads. In such a situation, simple ledgers, decorative brackets, in-fill framing or other forms of support may be added beneath the connection area as required.

  12. Stavebolt Device in Shear Performance: (not illustrated) Although the Stavebolt device has not specifically been performance tested to resist shear loads, in some instances we have extended the pipe section several inches into the abutting member to transfer shear loads between the members. This may work well, for example, where several Stavebolt units are to be installed in the same end of a deep glulam post or beam, where shrinkage in the timber is not a factor.

  13. Shrinkage in the timber: (not illustrated) Various methods of adjusting for shrinkage in the timbers may be applicable to some Stavebolt installations. Where tension rods or tie bolt-ends are left exposed for later tightening, the solution is simple, even when hidden by counter-boring. In situations where the end of the tie-bolt is not accessible following assembly, various die springs and/or spring-washers positioned under the nut or head of the bolt and compressed during installation, may be used to take up a measurable amount of the slack. In some situations, a Stavebolt with a HD die-spring built into the pipe section have been used successfully to maintain tight contact between shrinking members.
