  • the example provided above is typical for wall, floor and roof construction. While the embodiment connector of the first type is composed of a fibre reinforced plastic, any rigid block composition of sufficient strength is within the broadest scope.
  • the holes in the connector in the broadest aspect are limited to holes in which bolts are slidingly passed therethrough or threaded holes able to accept screws or unthreaded holes able to accept screws - in its broadest aspect
  • the invention extends to connectors with any holes suitable for receiving a fastening element of any type.
  • bolt refers in its broadest sense, unless the context requires otherwise, to a fastening element being adapted to engage with a constant diameter threaded nut, free or embedded, or an embedded threaded sleeve. Accordingly, while it is preferred to use nut receiving slots for removable nuts in the embodiment shown above, alternative embodiments with restricted functionality can use embedded threads which cannot be removed.
  • the term “screw” refers to a tapered fastening element adapted to screw into the hole of the connector, typically able to tap its own thread in the hole.
  • side and side faces in the claims are intended to be interpreted in terms of the different functions of the described sides or side faces rather than visually and extend to surfaces which may not be recognisably distinct or uniformly flat and which may continuously curve into adjacent sides or faces.
  • the invention in its broadest aspect extends to systems where the one or more holes on one or more faces include one set of holes for performing the function of fastening the connector to the C-channel members and another set of holes for performing the function of fastening the connector to other connectors, as well systems where some or all of the holes can form both functions .
