Definitions

  • the invention relates to a corner connection in a support system, which is formed from at least two angled truss girders, the respective truss having main supporting parts and supporting elements connecting them, which have bars or are formed by bars.
  • Support systems with corner connections are used for the most diverse Purposes used, for example in connection with traffic and signposting facilities.
  • the support systems have, for example, a support anchored in the floor in the manner of a support, to which, in particular at a right angle, another support in the form of a cantilever arm is connected, which supports the traffic or signpost device.
  • the support system can, for example, also consist of three supports, namely two vertical supports anchored in the floor, which are connected in the manner of a bridge by means of a horizontal support, with which the support system has two corner connections.
  • Such U-shaped support systems are used when traffic routes have to be bridged.
  • a corner connection in a support system of the type mentioned is known from practice.
  • the respective girders are designed as truss girders and the supporting elements are formed directly by rods which are welded to the main supporting parts.
  • the corner connection of the angled trusses is also done by welding them.
  • the truss girders are made of steel.
  • the object of the present invention is to provide a construction of a corner connection which is simple in terms of construction and assembly in a support system of the type mentioned at the outset.
  • the object is achieved with a corner connection of the type mentioned at the outset in that the main supporting parts which form a corner and are arranged at an angle to one another are connected to one another by means of an angle element.
  • the main support parts are connected there via an angle element.
  • the angle element is preferably connected to the respective main supporting part by means of separate fastening elements, for example by means of a secured screw connection, a bolt connection etc.
  • a non-welded corner connection of the Support systems offer the basic possibility of assembling the support system as a whole from individual components, i.e. connecting the main support parts and the support elements connecting them to one another via fastening elements, thus also dispensing with a welded connection here and thus being able to loosen the angle elements if necessary.
  • Aluminum or an aluminum alloy is regarded as the preferred material for the essential components of the support system, namely the main support parts, the rods and the angle elements, which means that the support system is relatively light compared to steel and also takes into account the problem that aluminum or an aluminum alloy can only be welded with increased effort.
  • a special design provides that the respective main support part is designed as a tubular extruded profile, into which the respective angle element with its end attachment assigned to it can be inserted.
  • the outer dimensions of the annular end lug are matched to the inner dimensions of the main support part in such a way that the end lug can be inserted into the tubular opening of the main support part with little play.
  • the permanent connection between the angle element and the main supporting parts is, as described above, preferably via a secure screw or bolt connection.
  • the angle element is preferably used to connect two main support parts angled at an angle of 90 °.
  • the angle elements according to the invention are also suitable for connecting main support parts which are arranged at an angle which deviates from a right angle to one another.
  • the respective truss has four main supporting parts arranged parallel to one another and supporting elements connecting them, the corner connection of two angled trusses being made by means of four angle elements. Each angle element thus connects those arranged adjacent to one another Main supporting parts of different trusses.
  • a special embodiment of the invention provides that the respective angle element has at least one receptacle for fastening a rod, with which this rod is connected on the one hand to the said angle element and on the other hand to another angle element or another main supporting part.
  • the angular element is thus also forcefully integrated into the support system via the at least one rod and thus stiffens it in the area of the corner connection.
  • the respective angular element has a plurality of receptacles for fastening rods, at least one of the rods having its end remote from the angular element being connected to a main support part and another of the rods having its end remote from the angular element being connected to another angular element.
  • the first-mentioned angular element not only introduces forces into another angular element, but also into a truss girder assigned to the corner connection.
  • the respective angle element has a plurality of receptacles for fastening the rods in different planes.
  • an arrangement of the rods in three perpendicular directions x, y and z is intended.
  • the corner connection described above makes it possible to design support systems that consist of largely standardized components that do not have to be welded.
  • the support system can also be installed in a modular system.
  • the pivotable articulation of the support elements, in particular the rods, on the main support parts makes it possible to generate different, statically desired angles of attack of the rods on the main support parts.
  • the constructions can be pushed together or pulled apart as desired.
  • the support system shown in Figures 1 to 3 in a highly simplified representation is essentially formed by three truss girders, namely the vertical truss columns 1 and 2 and the horizontal truss bridge 3 connected to them, on which, shown with dashed lines, a sign 4 in is not shown in more detail, which includes the traffic or signpost device, which is also not illustrated.
  • the two truss columns 1 and 2 and the truss bridge 3 are constructed identically in principle, that is to say they have identical main supporting parts 5, which extend over their entire length, as well as identical rods 28 and identical connecting elements 27.
  • the truss support 1 or 2 has a bearing plate 8 connected to it, and the two ends of the truss bridge 3 are connected to the truss supports 1 and 2 via the corner connections 64 according to the invention.
