Definitions

  • the present invention relates to a structural node joint of the kind set forth in the preamble of claim 1.
  • Such a structural node joinT is known inter alia from US Patent Specification No. 4.353.662.
  • the access opening has a substantial size in relation to the hollow connecting member as a whole, and is closed by a relatively large cap-shaped cover, which is secured to the remainder of the connecting member by means of a through-going bolt.
  • the substantial size of the access opening results in a considerably reduction in the mechanical strength of the connecting member, and hence of the mechanical strength of the complete joint comprising this connecting member.
  • the embodiment set forth in claim 2 makes it possible to use also the closure member for attaching a rod-shaped or tubular element included in the joint.
  • This element may e.g. be provided with or end in a threaded stub, that may be screwed into a corresponding threaded bore in the closure member.
  • the embodiment set forth in claim 6 makes it possible to give all those members, with which the various rod-shaped or tubular elements are attached to the connecting member, identical shape, as when used with the attachment holes, the screw heads function in the normal manner as abutment means, whilst the screw heads securing elements facing the access openings are screwed into the threads in these openings.
  • the present invention also relates to a hollow connecting member for a structural node joint according to the invention.
  • This connecting member is of the kind set forth in the preamble of claim 7, and according to the present invention, it exhibits the features set forth in the characterizing clause of claim 6.
  • the structural node joint shown in Figure 1 comprises a hollow connecting member 1, which in the example shown is spherical, but generally may have any shape suitable for the particular application in question.
  • a hollow connecting member 1 which in the example shown is spherical, but generally may have any shape suitable for the particular application in question.
  • an attachement screw 7 and 8 has been inserted in the hole 3 and one of the holes 4 respectively, the heads 9 of said attachment screws being tightened up against the inside of the wall 2, their shafts 10 being screwed into the ends of two structural rod elements 5 and 6 respectively, of which only the ends are shown.
  • the structural rod elements 5 and 6 may be contructed in any manner and from any material being suitable to the particular application in question, but they will not be described in more detail in the present application, since their construction and shape have no direct bearing upon the present invention, with the exception of what is required for the cooperation with the connecting member 1.
  • the wall 2 has an access opening 11, which is somewhat larger than the attachment holes 3, viz. just large enough to make its clear diameter 13 a trifle larger than the largest diameter of the screwheads 9 and their associated washers 19, so that all those attachment screws 7 and 8, that are to be used for attaching the rod elements 5 and 6, may be introduced through the access opening 11 and be placed in the attachment holes 3 and 4 and screwed into the ends of the rod elements 5 and 6 respectively using suitable tools (not shown).
  • the latter may be closed by a threaded plug (not shown), that is screwed into the thread 14 in the opening 11, but in the exemplary embodiment shown in Figure 1 the access opening 11 has screwed into it a closure bushing 12 with an external thread 15 corresponding to the thread 14 in the opening 11.
  • the ball in the closure bushing 12 has a thread 20 cooperating with a corresponding thread 21 on a threaded stub 22, the latter constituting part of or being secured to a further structural rod element 16.
  • the attachment screws 7 and 8 shown in Figure 1 have hexagonal recesses 18 for cooperation with a correspondingly hexagonal spanner.
  • the screws may e.g. be of the kind marketed under the trade mark "Unbrako", and the use of these or other standard screws results in the advantage that the joint may be based on the use of ready-made, possibly heat-treated and/or corrosion-protected screws, that would be relatively costly to produce in small numbers, with the exception of the possible attachment of a further structural rod element 16 to one ore more closure bushes 12.
  • spherical washers 19 are placed between these parts in a manner known per se.
  • the attachment screw 7 extending through the attachment hole 4 to the right in Figure 1 may be introduced through the access opening 11 relatively easily, before this opening is closed by the closure bushing 12, e.g. by using a straight hexagonal spanner, which can also be used for tightening the screw.
  • a straight hexagonal spanner which can also be used for tightening the screw.
  • the introduction of each screw may require the use of special tools (not shown), while the tightening in many cases may be achieved by introducing a straight hexagonal spanner through an oppositely situated attachment hole. In other cases it will be necessary to use a hexagonal spanner with an articulated shaft when tightening the attachment screws.
  • the connecting member 1 may comprise further attachment holes and possibly also one or more further access openings in front and behind the sectional plane.
  • connection member 1 As material for the connecting member 1 proper, steel of a strength suited to the particular application may suitably be used. Before the last opening - normally the access opening 11 - is closed completely, a suitable rust-protecting agent may be introduced or injected into the cavity in the connecting member 1.
  • the screw 25 securing the rod element 16 may in the manner shown be provided with an annular spacer 30, that ensures that the thread engagement between the head 26 and the opening 11 is situated suitably far into the latter.
  • the rod element 16 is attached by simply first screwing the screw 25 into the rod, preferably with the annular spacer 30 in place as shown in Figure 2, whereupon the unit consisting of the rod element 16 and the screw 25 and possibly the spacer 30 is screwed into the opening 11 until the abutment surface 17 abuts against the outside of the wall 2.
  • central ducts my be formed in the rod elements 5, 6 and 16 and in the attachment screws 7 and 8 or 23-25, said ducts making it possible to blow dry air through the grid structure and/or to draw e.g. electrical wires for lamps, loudspeakers and the like, which are suspended in or secured to the grid structure.
