Definitions

  • This invention relates to a connection between a steel I-beam member and a wooden panel, preferably in the form of a cross-laminated timber panel.
  • the connection is made by providing openings in the top flange of the steel I-beam and then using angled washers inserted in the openings to direct screws at a selected angle through the openings and through the washes and into the wooden panel.
  • the present invention is particularly useful for creating composite roof or floor panels in a building. Combining one or more steel beams with the wooden panel strengthens the wooden panel which allows the wooden panel to be made larger and thus to allow for a single panel to span a greater distance.
  • the panel taught in Longpre et al is connected to the trusses by embedding the trusses in cement panel during the setting of the concrete.
  • the panel taught in Sattler is connected to the I beam by embedding studs which are welded to the I- beam in the concrete panel.
  • connection of the present invention provides a reliable means by which the strength of a panel can be improved.
  • the connection of the present invention improves on the prior art by incorporating a number of design features that make it lighter and cheaper to produce while withstanding sufficiently high loads.
  • the present invention is a connection made between a panel made from wood and a beam, which is generally made from steel.
  • the beam is an I-beam.
  • the connection is made with a plurality of separate fasteners and angled washers.
