Brackets and Hangers for Post and Beam Construction.....
Post and Beam, joist hangers and brackets, were designed and used in the late 1800’s and into the 1900’s. Most of the buildings were of the commercial type. Ware houses, carriage barns and cow barns. In northern New Hampshire, and New York State, structures still stand , showing example of the durability of the old style,over built, strong, hangers and brackets.
At the Rocks Estate, in Bethlehem New Hampshire, stands a Carriage Horse Barn, designed by Isaac Elwood Scott, in 1884. The barn and other structures at the Estate are still in perfect shape, as the pictures illustrate.
My own home was built from brackets, I recovered from a horse carriage built in 1910 at the Mount Washington Hotel. I modeled the brackets I have had manufactured from these. With the advent of Stress skin Panels, residential homes can be built that are very energy efficient.
- Recently, it has become common practice to entirely surround the timber structure in manufactured panels, such as SIPs (Structural Insulated Panels). This method has benefits: the timbers can only be seen from inside the building, but is less complex to build and provides more efficient insulation. Structural Insulated Panels are commonly two rigid composite materials usually wood-based like OSB or plywood with a foamed insulation material innard, between either gluing billets as in EPS (Expanded Polystyrene) or formed in place with foaming polyurethane. Another advantage is less of a dependency on extraneous bracing and auxiliary members, minor joists and rafters, as the panels can span considerable distances and add greater rigidity to the basic timber frame.
- Post and lintel, “prop and lintel” or “trabeated” is a simple construction method using a lintel, header, or architrave as the horizontal member over a building void supported at its ends by two vertical columns, pillars, or posts. This architectural system and building method has been commonly used for centuries to support the weight of the structure located above the openings created by windows and doors in a bearing wall. Post and lintel is different than a beam joined between two posts, it must pass over the tops of the supports. Post-and-beam is a general term for any kind of timber framing.
