Definitions

  • the invention relates to a truss-like busbar arrangement, as has become known from DE-A-29 15 502.
  • two busbars are held together in an upright arrangement on the foot and head side by means of special foot and head connectors.
  • Two such double-track busbars are fastened to one another via two equally long, horizontally extending binders composed of two half-shells. This is done in such a way that insert pieces provided at the end face of each binder engage in the slot of the busbar, that is to say in the adapter receiving channel, which, as is known, receives the relatively sensitive insulating material carrier containing copper conductor rails.
  • the adapters of spotlights are plugged into the adapter receiving channel between the attachment points on the binder side and are intended to illuminate exhibits held on the binders, for example.
  • the truss-like busbar arrangement known from DE-A-29 15 502 is both in terms of their load-bearing capacity and their usability are limited.
  • this known truss-like busbar arrangement a basic way has already been shown of not only using busbars as a supporting element of lights, but also integrating them into a truss-like supporting structure.
  • the invention is based on the object of further developing the known truss-type busbar arrangement so that, with expanded application options, it also has a significantly higher load capacity with the possibility of also having large spans free to bridge. This object has been achieved in accordance with the features of patent claim 1.
  • the fastening grooves of the two hollow profiles face each other, the two fastening grooves serving to attach connecting parts which fasten the two hollow profiles to one another, the adapter receiving channel of the conductor rail is available solely for electrical feeding or removal purposes.
  • the invention therefore creates a separation of the carrying or fastening function and the electrical supply function, the latter in particular of lights. In this way, both functions can not hinder each other, as is the case, for example, with the subject of DE-A-29 15 502.
  • the adapter receiving channel serves both for current consumption by means of an adapter and for fastening two slotted tube-like hollow profiles of a pair of hollow profiles to one another.
  • the conductor rail according to DE-A-29 15 502 has an axial fastening groove on its outside diametrically opposite the axial slot opening (adapter receiving channel), but this fastening groove only serves to hold fastening parts for the ceiling-side cable or pendulum tube holder, but not for fastening two Busbars to each other (S.DE-A-29 15 502 p.5 paragraph 3; p.9 paragraph 4) Fastening grooves on power rails are known per se from DE-C2-28 10 681.
  • a rigid connecting part is created according to the invention have been, the fastening areas are arranged at least in a square, so - in contrast to the truss module according to DE-A-29 15 502 - are widely spaced apart in a statically favorable manner with respect to one and the same hollow profile.
  • the rigid connecting part can either be plate-shaped or cross-shaped in accordance with other features of the invention, in particular in the manner of a St. Andrew's cross containing oblique struts.
  • a truss module according to the invention is therefore constructed such that in the horizontal arrangement of such a module, in which, however, the two hollow profiles of the pair of hollow profiles lie vertically one above the other or next to one another (comparable to an I-beam), e.g. the upper hollow profile forms the compression belt when loaded and the lower hollow profile forms the tension belt.
  • Truss modules according to the invention can be arranged axially one after the other and can be coupled to one another on the end faces of their hollow profiles in a tensile and compressive manner. By inserting tensile and pressure resistant into the hollow profiles and also fastened there insert pieces ensures that with the invention Truss modules can span very large spans.
  • the truss modules according to the invention can overall form a truss structure or, in a parallel arrangement of similar truss modules next to one another, can form box-like supports with a corresponding cross connection.
  • the truss modules according to the invention can be used, for example, to create portals or portal groups or truss-like ceiling structures.
  • the truss modules according to the invention can be used with particular advantage in exhibition halls.
  • individual room structures with an additional supporting function can be created, which allow even larger exhibits to be illuminated from all directions, in particular also from above - and also allow a room separation function.
  • a truss module with larger transverse width with M1 and a truss module with smaller transverse width are designated with M2.
  • the truss modules M1, M2 (see M2 meet at the joints marked with S against each other.
  • Each truss module M1 and M2 has a pair of hollow sections, which consists of two busbars 10. These busbars 10 are attached according to the different cross-sections W 1 (larger cross section) and W 2 (smaller cross section) by means of different connecting parts K 1, K 2 spaced apart.
  • the connecting parts of the truss modules M1 are designated with K1 and the connecting parts of the truss modules M2 with K2.
  • Each connecting part K1, K2 consists of two oblique struts 11, 12 arranged in the manner of a St. Andrew's cross, which are arranged in the same plane and represent an overall rigid component because of their integral, integral connection in the central node region 13.
  • connecting crosses K1 large connecting cross
  • K2 small connecting cross
  • the connecting parts are integrally-integrally connected light metal die-cast parts, the cross section of the oblique struts 11, 12 being approximately I-shaped, as is e.g. 3, that is to say each has two flanges 14 and a web 15 connecting them.
  • the webs 15 are provided with openings 16 (as in a Vendeel beam, for example).
  • each fastening foot 17 carries at the end a foot plate 18 with a support surface 53, which is supported on a filler 19, which is accommodated relatively snugly in the approximately omega-shaped fastening groove 20 of the respective busbar 10 (see also hollow profile 10a of FIGS. 4 and 5) .
  • each slotted tube-like busbar 10 has a slot, i. an adapter receiving channel 21.
  • the adapter receiving channel 21 contains axially extending and oppositely arranged insulating material profiles 22, each of which receives a metal conductor, for example a copper flat conductor 23.
  • a metal conductor for example a copper flat conductor 23.
  • the fastening feet 17 of the connecting crosses K1 and K2 contain accessible internal thread receptacles 24 for fastening screws 25 from the support surface 53.
  • the fastening screws 25 penetrate the bottom 26 of an elongated, approximately U-shaped Steel connector 27 and also the bottom 28 of the busbar 10 from the adapter receiving channel 21.
  • the joints S are fastened to one another in the longitudinal direction x successive busbars 10 in a tensile and compressive manner, while at the same time a firm connection of great force absorption capacity is achieved between the mounting feet 17 and the omega-shaped mounting grooves 20 of the busbars 10.
  • the steel connecting pieces 27 with cams 29 arranged above their base 26 correspondingly form coupling holes 59 of the same shape within the base 26.
  • the coupling holes 59 are designated in more detail in FIG. 6 .
  • FIG. 1 leads to a larger grid-like connection according to FIG. 2.
  • vertically standing truss modules M1 supports or columns, which rest with feet 30 on an installation level and remove a grid-like truss structure on the top side via a flat articulated connection 31, in which the modules M 1 with larger cross width W 1 are penetrated by modules M 2 with smaller cross width W 2 are.
  • spotlights 32 are connected on the lower busbars 10 of the modules M1 but also on the lower busbars 10 of the truss modules M2, spotlights 32 are connected.
  • rope braces 33 can also be provided - in the present case running in a cross shape.
  • spacer tubes 34 can be provided in the upper corner region. Instead of these spacer tubes 34, it is also possible, for example in the upper third of the column-like truss modules M 1, that is to say at the penetration points designated 35, to let truss modules M 2 pass through, the connecting crosses K 2 of which then extend in a horizontal plane would, while the smaller connecting crosses K2 shown in Fig. 2 extend in a vertical plane.
  • the truss modules M1 each with four meters of axial individual length in the axial direction x follow each other, so that in this case the free span (portal width) in the direction x between two opposite joint supports 31 is twelve meters.
  • FIG. 3 Analogously, a portal half is shown in the embodiment according to FIG. 3 jur.
