Definitions

  • This invention relates to a joint and to components of such a joint for joining drywall panels and plasterboards of wall and ceiling structures in such a manner that it at least partially eliminates the need for nails, screws or the like fasteners.
  • Drywall which commonly consists of a thin layer of gypsum between two layers of heavy paper, is widely used for walls and ceilings in most buildings today because it is both faster and cheaper to install than brick, mortar and plaster. Drywall panels are commonly fastened to inside wall and ceiling frameworks of residential houses, offices and other buildings. In particular, edges of adjacent drywalls are butted together and fastened to the framework by means of nails or drywall screws to form so-called butt joints between adjacent panels.
  • a further disadvantage is that nails or screws can be forced too deeply into the drywall, causing the paper to break.
  • the fasteners must be set just a little below the surface to leave a shallow dimple without breaking the paper on the drywall. This dimple gets filled with joint compound later.
  • fastener heads are not sunk deeply enough into the drywall, leaving an unsightly hump after application of the tape coat.
  • joint compound over the screw and nail heads shrink a little, and as such joint compound must be applied repeatedly to screw and nail heads to cover the same properly.
  • apertures resulting from nails and screws where they protrude through a drywall generally decrease fire performance of drywall structures at these locations. It is, inter alia, for this reason that manufacturers have very strict regulations about how many fasteners need to be used to attach drywall.
  • a drywall joint suitable for joining drywall panels of wall and ceiling structures wherein each drywall panel has an outer surface and an opposite inner surface, the joint comprising an outer joint section extending at least partially the height of and being disposed against the outer surface of the drywall panels; an inner joint section extending at least partially the height of and being disposed against the inner surface of the drywall panels; and connectors for coupling the outer and the inner joint sections together to sandwich the drywall panels between the outer and inner joint sections, the connectors comprising first engagement formations on one of the outer and inner joint sections, and correspondingly positioned second engagement formations on the other of the inner and outer joint sections, the first engagement formations being so positioned and shaped that they pass through the drywall panels to inter- engage with the second engagement formations in the other of the inner and outer joint sections when the outer and inner joint sections are coupled together.
  • a plurality of panels may be joined in the above fashion.
  • drywall should be interpreted also to include and refer to plasterboard, sheetrock, wallboard, gypsum board, and the like.
  • panels should be interpreted to include panels commonly used in the art for example wood panels and Nutec panels.
  • the joint may be adapted to adjoin adjacent drywall panels in a side-by-side fashion wherein one drywall panel forms a junction with another drywall panel, the joint arrangement being such that the outer joint section is disposed against the outer surface of the drywall panels at the junction; the inner joint section is disposed against the inner surface of the drywall panels at the junction; and the first engagement formations of the connectors are so positioned and shaped that they pass through the junction intermediate the drywall panels to inter-engage with the second engagement formations in the other of the inner and outer joint sections for coupling the outer and the inner joint sections together.
  • the joint may be adapted to adjoin adjacent drywall panels in an angular fashion relative to each other wherein one drywall panel forms a junction with another drywall panel at a corner zone.
  • two outer joint sections may extend at least partially the height and be disposed against the outer surfaces of the two drywall panels at the corner zone;
  • the inner joint section may extend at least partially the height and be disposed against the two inner surfaces of the drywall panels at the corner zone; and the first and second engagement formations may inter-engage such that the inner joint section is nestled in the corner zone.
  • the first engagement formations may comprise tongue formations on one of the outer and inner joint sections
  • the second engagement formations may comprise grooves on the other of the inner and outer joint sections that are complimentary dimensioned to receive the tongue formations therein.
  • the second engagement formations may be grooves on the inner joint section
  • the first engagement formations may be tongue formations that extend from the outer joint section and engage in the grooves in the inner joint section.
  • the engagement formations may comprise a single engagement formation, such as a single tongue formation and/or a single groove formation or may comprise a plurality of tongue formations and/or groove formations.
  • the tongue formations may define lateral hook or barb elements, lugs, or beads that engage the second engagement formations.
  • the first and second engagement formations of the joint may engage in the form of a snap-fit.
  • the inner joint section may be separate from the outer joint section. In a preferred form of the invention the inner joint section extends the height of the drywall panel.
  • the inner joint section may comprise an elongate body having a substantially U- shaped or square transverse cross-sectional profile.
  • the inner joint section may include at least one groove, extending the height of the inner joint section, in at least two legs, but preferably three legs of the U-shaped or square elongate body.
  • the inner joint section may be reinforced at each corner zone between adjoining legs of the elongate body.
  • the inner joint section may include a spacer dimensioned to locate between and space the free ends of the inner joint section to prevent the same from bending towards each other in use.
  • the inner joint section may be dimensioned matingly to engage a neighboring inner joint section, thus increasing the spacing between two parallel walls in a double- walled structure.
  • the outer joint section may include the tongue formation and two legs laterally extending from the tongue formation, the tongue formation being dimensioned to locate in the grooves on the inner joint section, and the legs being dimensioned to locate against the outer surface of drywall panels.
  • the arrangement may be such that the drywall panels are sandwiched between the legs of the outer joint section and the inner joint section.
  • the outer joint section may include a double-beaded tongue formation having a first bead, which is dimensioned to locate in the grooves on the inner joint section, a second bead following the first bead, and the two legs laterally extending from the second bead of the tongue formation, the arrangement being such that the second bead serves as a groove for receiving the tongue formation of an abutting other outer joint section.
  • the arrangement may be such that the legs of a first outer joint section may be forced open by the tongue formation of a second outer joint section such that the first bead of the tongue formation of the second outer joint section locates in the second bead of the tongue formation of the first outer joint section.
  • the joint may be adapted also to join at least two, but possibly more, parallel and abutting drywall panels to each other to form a double-walled structure, wherein each drywall panel has an outer surface and an opposite inner surface and wherein the panels are positioned such that the outer surface of a first drywall panel abuts the inner surface of a parallel second drywall panel, the arrangement being such that a first outer joint section is disposed against the outer surface of the first drywall panel; an inner joint section is disposed against the inner surface of the first drywall panel; connectors are disposed for coupling the first outer joint section to the inner joint section to sandwich the first drywall panel between the first outer joint section and the inner joint section, particularly the tongue formation of the first outer joint section passing through the first drywall panel to inter-engage with the grooves on the inner joint section; a second outer joint section is disposed against the outer surface of the second drywall panel; the tongue formation of the second outer joint section passing through the second drywall panel to inter-engage with the tongue formation of the first outer joint section,
  • the joint may be adapted also to join at least two parallel drywall panels, as described in the immediately preceding paragraph, in spaced relationship to each other to form a double-walled structure, wherein each drywall panel has an outer surface and an opposite inner surface and wherein the panels are positioned such that the inner surfaces face each other, the arrangement being such that a first outer joint section is disposed against the outer surface of one drywall panel; a second outer joint section is disposed against the outer surface of the other drywall panel; the inner joint section is disposed intermediate and against the inner surfaces of the two drywall panels; the connectors are disposed for coupling the two outer joint sections to the intermediate inner joint section to sandwich each of the drywall panels between an outer joint section and the intermediate inner joint section, the connectors comprising first engagement formations on either of the outer and the inner joint sections, and correspondingly positioned second engagement formations on the other of the inner and outer joint sections, the first engagement formations being so positioned and shaped that they pass through the drywall panels to inter- engage with the second engagement formations in the other of
