Definitions

  • the invention relates to a welding corner connector of hollow chamber profiles, with one on the outside of a hollow chamber adapted insert body, the one at a first end has weldable connection surface and that at a second end is formed with cross-expandable end sections, and with one between the end sections on this when actuated spreading expansion element.
  • a welding corner connector with the aforementioned features is known from EP-A-0 288 756.
  • the well-known expansion element is an expansion dowel, an expansion wedge or the like, which either by tightening a screw and / or by moving it axially achieved the spread that is necessary for itself the welding corner connector sticks in the hollow chamber profile.
  • the Extent of the axial fixation required Axial movement is dependent on the tolerances of the involved components differently. There may therefore be irregularities when fixing the corner connector axially different parts of the hollow chamber profile come which may affect connection security.
  • the invention is therefore based on the object Welding corner connector with the characteristics mentioned above to improve that improved, especially the welded corner connector sits more securely in the hollow chamber profile results.
  • the expansion element is exclusive adjustable and only a rotary adjustment of the Spreading element leads to the desired spreading of the end sections of the insert body.
  • the welding corner connector trained such that an unintended Turning back of the expansion element is excluded. It is as a result not possible that the clamp of the welded corner connector is unwanted loosened in the hollow chamber profile.
  • a rotary adjustment of the expansion element Advantage that the jamming takes place on a short angle of rotation can. So there are no significant rotary adjustments required, for example as a result of one used for the spread flat screw thread to the expansion element to fix. In conjunction with a torque wrench can be ensured that a secure clamping under structurally predetermined conditions of a single Axial position is reached.
  • the welding corner connector consists of only two components. These components are structurally coordinated so that the actuation of only the expansion element is sufficient, So a single element to fix the weld corner connector to achieve in the hollow chamber profile.
  • the stake another component causing an adjustment, for example a screw is avoided.
  • a use of metal can be superfluous. This can also lead to weight loss contribute.
  • the welding corner connector can be designed such that the expansion element with the insert body in a predetermined Axial position is locked rotatably.
  • the latch causes the expansion element and the insert body always take the same axial relative position to each other, so that the spreading element is always spreading in the same axial position acts on the end portions.
  • the assembly of the Spreading element and the plug-in body takes place via a advantageous latching in terms of assembly.
  • the welded corner connector is expediently designed in such a way that that the locking of the expansion element with a longitudinally slotted pin is made with a pin head engages behind a collar of the plug-in body.

  • the pin on the connection surface side one, if necessary, arranged with an interchangeable insert has non-circular actuation recess.
  • Non-circular actuation recesses are special for achieving rotary adjustments suitable. They also allow significant operating forces to transfer, namely with accordingly out of round Operating tools. It is particularly advantageous if the pin is provided with an interchangeable insert, so that for example an internal hexagon recess through an internal square recess can be replaced to different Operating tools and / or operating forces to be able to.
  • the welding corner connector In order to save weight, it is advantageous to Design the welding corner connector so that the insert body at least in the area of its end sections and / or that Spreading element at least in the area of its actuating arms is / are thin-walled hollow. Even with this configuration the corner connector is the required strength and to achieve stiffness and in particular the required deformations of the cross-expandable end sections facilitated.

  • the welding corner connector can be in the area of its end sections be specially adapted. It is particularly advantageous if provide the end sections of the insert body with ramp surfaces are those with increasing angle of rotation of the actuating arms of the expansion element increasingly protrude into their outer circumferential path. With the contact surfaces, the contact pressure can be between the end sections and the hollow chamber profile for a predetermined expansion element in relation to the actuation angle of rotation be determined.
  • the run-up surfaces are expedient trained so that the largest possible and necessary Clamping force between the end sections and the hollow chamber profiles for maximum tolerances of the components involved is reached at the end of the ramp area.
  • the ramp surfaces have thin walls protrude from the end portions and with their end edges the end sections are supported.
  • the ramp surfaces can be shaped according to the clamping conditions without doing so to increase the mass of the weld corner connector over the fee.
  • the end support of the ramp surfaces ensures that required stabilization and can be trained that the clamping forces introduced in the desired direction act on the end sections.
  • the welding corner connector can be designed so that the run-up surfaces of a rectangular insert body each are assigned to one of the side surfaces, the narrow Ramp surfaces assigned to side surfaces each by one longer actuating arm matched to half the long side and the ramp surfaces assigned to the wide side surfaces each from one to the half narrow side shorter actuating arm are applied.
  • the expansion element remains with its axis coaxial or axially parallel to Hollow chamber profile or to the insert body. A tilt of the Spreader element is avoided and resulting impairments the clamping of the end sections in the hollow chamber profile do not occur.
  • the welding corner connector in such a way that that the ramp faces towards the pad are inclined towards the connector axis. With the help of inclination the ramp surfaces can be achieved that the expansion element can be inserted without disabilities and without play sits in the insert body by the spring action of the end portions is used for this.
  • ends of the operating arms are spherical, act these ends and the run-up surfaces also in the case of production-related Tolerances in the shape without abrasion are flawless together.
  • the expansion element is not unintentionally turns back. If this is the case with the given Forming the expansion element and insert body or ramp surfaces cannot be easily achieved, it is advisable the weld corner connector so that at least a ramp surface and / or at least one actuating arm Provide friction-increasing agents on the contact surface is.
