Definitions

  • This disclosure generally relates to using timber in building construction. Specifically, this disclosure relates to a wood joint for joining wood planks together in the construction of a building or other structure.
  • Wood has been used as a construction material for more than a thousand years.
  • Horyu-ji Temple in Japan is believed to be the oldest wooden building in the world, which was built more than 1,300 years ago.
  • nonresidential buildings have mainly been constructed utilizing reinforced concrete and steel, such as post-tensioned concrete and steel framing.
  • nonresidential buildings built out of timber or engineered wood were relatively uncommon for most of the twentieth century.
  • CLT cross-laminated timber
  • Mass timber is a family of engineered wood products and is also known as a type of building (similar to a steel building or a concrete building). Mass timber includes but is not limited to CLT (cross-laminated timber), NLT (nail-laminated timber), GLT (glue- laminated timber), MPP (mass-plywood panel), DLT (dowel-laminated timber), and other similar materials.
  • CLT is a mass timber product that is a multilayer wood panel consisting of several overlying board layers. As a result, mass timber is becoming an increasingly popular material for the structural systems and other portions of buildings.
  • mass timber panels facilitate improved quality and speed of construction by enabling prefabrication workflows.
  • Wall, floor, and roof elements may be manufactured in a climate-controlled facility and transported to construction sites for rapid assembly.
