Definitions

  • the objective of the invention is to provide a quick cost effective connector for connecting timber frame walls or wall panels to a range of floor and roof constructions and which acts as a structural distributor for wind and earthquake loadings, inclusive of in-service loads.
  • the connector is economic in material content and simple to install and inspect.
  • the connector is lightweight , is made of commonly available sustainable materials of standard sizes, resulting in minimum waste for maximum efficiency and its manufacture is low in energy use.
  • the connector can be made in a range of modular lengths of various widths and thicknesses to be used for a range of wall layouts and configurations.
  • the connector is ideally suited for use where standardised componentry is required as in modular or prefabricated single or multi-storey buildings.
  • bottom and top plates of walls are vital components of a building, particularly where they act as bracing elements against the three forces of tension (uplift), in-plane and out-of-plane shear, the last two being defined as lateral loads.
  • Tension under wind loading is required to fix down the roof in both braced and non-braced situations and to prevent wall overturning (wracking) for braced situations.
  • Walls supporting multiple storeys have greater lateral load than those supporting only a roof.
  • Lower storey walls serve to resist an accumulation of lateral load from upper storey levels.
  • anchors or a method of fixing the top and bottom plates of walls to distribute these forces to floors down to foundations and then to earth, is a vital component of a building, the most important being the anchorage of bottom wall plates.
  • the invention is a connector comprising a grooved plate which can be of solid timber, finger-jointed timber or engineered lumber such as glue-laminated timber or laminated veneer lumber or structural composite lumber such as parallel strand lumber or oriented strand lumber, or fibre-reinforced cementitious materials, with a strip of an engineered panel product glued into the plate's groove to form an engineered timber section.

  • the grooved plate acts as a wall's top and/or bottom plate and the strip, glued into the plate's groove, fixes the plate to the side of the floor and/or roof structure, with both components working in unison to absorb and distribute lateral loads and tension, from wind and/or earthquake forces, to floor systems, foundations and to earth.
  • the groove is made in the bottom face of the bottom plate and in the top face of the top plate.
  • the groove can be centred in the plate or offset towards the wall's outer face to achieve a higher degree of contact restraint of the wall to lateral loadings.
  • the strip provides lateral load and tension distribution to predetermined and drilled, evenly distributed or specific anchorage points of the wall for both roof and floor systems and allows easy visual inspection of the fixings,
  • the connector being a standardised component, with predetermined parameters, simplifies the decision-making process as to the type of anchorage to use, its positioning, installation method and fixing penetration.
  • finger-jointed timber, engineered lumber or structural composite lumber allow long plate runs and provide straightness and continuity and negate the use of in-line structural fixings.
  • Engineered lumber or structural composite lumber impart a higher degree of stiffness and resistance to bending stress in the axial line of the member.
  • the plywood strip When required the plywood strip can be thickened increasing the limit to stress tolerance.
  • the strength of the plywood in the plate groove is because plywood is always made up of an unequal number of veneers.
  • the two veneers on the outside are parallel in fibre or grain direction and the next inner veneer or veneers have a fibre direction transverse to this. It follows that maximum adhesion of the plywood strip into the plate groove is achieved when the outer

Abstract

L'invention porte sur un raccord de mur servant à fixer des murs (10) aux systèmes de plancher (7) et de toit (6) pour bâtiments mono- et multi-étages à ossature en bois. Le raccord comporte une plaque en bois ou en dérivé du bois (la), en forme soit carrée ou rectangulaire en coupe transversale, comportant une rainure continue (3) sur une face. Une bande (2) est insérée et liée à d'aide d'une colle dans la rainure de la plaque et s'étend suffisamment à partir de la face vers les fixations de support structurelles (9) destinées à assembler le raccord aux systèmes de toit (6) et de plancher (7). La bande est éventuellement collée (4, 5) au toit (6) ou au plancher (7) au niveau de leur point de contact. La plaque et la bande agissent de concert afin d'absorber et de distribuer des charges agissant sur le mur et le toit au système de plancher du bâtiment, augmentant ainsi la capacité de charge de cisaillement du bâtiment.
