Definitions

  • the invention relates to a welding corner connector of hollow chamber profiles, with an outside of a hollow chamber adapted male body, which at a first end a weldable pad and has a second end is formed with transversely expandable end portions, and with one between the end portions of these on actuation spreading spreading element.
  • a welded corner connector with the aforementioned features is known from EP-A-0 288 756.
  • the known spreading element is an expansion dowel, a wedge or the like., Either by tightening a screw and / or by axial displacement achieves the spread necessary for it to the welding corner connector fixed in the hollow chamber profile.
  • the Extent of each required in this axial setting Axial movement is dependent on the tolerances of the different components involved. It can therefore lead to irregularities when setting the corner connector to axial different locations of the hollow chamber profile come, which can affect the connection security.
  • EP 0 897 047 A a document under Art. 54 (3) EPC, also discloses a welded connector of the beginning mentioned type, in which the expansion element in the male body only rotatably mounted and in one Spread of the end sections effecting position against unintentional Reverse rotation is secured.
  • the invention is therefore based on the object, a Weldable connector with the features mentioned in the introduction to improve that an improved, in particular Safer fit of the welded corner connector in the hollow section profile results.
  • the welding corner connector so designed such that the latching of the expansion element with a longitudinally slotted pin is made with a pin head engages behind an annular collar of the male body.
  • the assembly the expansion element and the male body takes place by simply pushing together until it clicks into place. Further Measures to assemble the from only two components existing welding corner connector are not required.
  • any Axial adjustment when attaching the welding corner connector is waived. Rather, the spreader is exclusive rotatable and only a rotational adjustment of the Spreizelements leads to the desired spreading of the end portions of the male body.
  • the welding corner connector designed such that an unintentional Reverse rotation of the expansion element is excluded. It is as a result not possible, that the clamping seat of the welding corner connector in the hollow chamber profile unintentionally loosened.
  • a rotational adjustment of the expansion element has the Advantage that the deadlock take place on a short rotation angle can. So there are no significant rotational adjustments required for example, as a result of a spread used flat-threaded thread to the spreader increase. In conjunction with a torque wrench can be ensured that a secure clamping under constructively predetermined conditions of a single Axial position is achieved.
  • the welded corner connector it is that it consists of only two components. These components are structurally coordinated that the actuation of only the expansion element is sufficient, So a single element to the setting of the welding corner connector to achieve in the hollow section profile.
  • the use another adjustment causing component, for example a screw is avoided. It can about it Be achieved in that the welding connector exclusively can be made of plastic. A use of metal may be unnecessary. That can also lead to a weight reduction contribute.
  • the welding corner connector may be formed so that the expansion element with the male body in a predetermined Axial ein is locked in rotation adjustable.
  • the locking causes the expansion element and the male body always take the same axial relative position to each other, so that the expansion element always in the same axial position spreading acting on the end sections.
  • the assembly of the Spreizelements and the male body takes place via a montageorial advantageous locking.
  • the pin connection surface side a if necessary arranged with a change of use Has non-circular actuating recess.
  • Unround operating recesses are special for achieving rotational adjustments suitable. They also allow considerable operating forces to transfer, namely with corresponding non-round Operating tools.
  • the pin is provided with a removable insert, so that so For example, a hexagon recess by a mecanicvierkantaus predominantlyung can be replaced to different Actuation tools and / or operating forces fair to be able to.
  • weld connectors so that the male body at least in the area of its end sections and / or the Spreading element at least in the region of its actuating arms thin-walled hollow is / are formed. Also in this embodiment of the corner connector are the required strengths and to achieve rigidity and in particular the required deformations of the transverse spreadable end sections facilitated.
  • a stiffening of the expansion element can be achieved when the welding connector is formed so that the expansion element between the pin and the actuating arms Has stiffening ribs. Which is between the pin and the actuating arms each extending stiffening ribs avoid an otherwise more massive and more material requiring Training of the expansion element and can also in Sensing a formation of the expansion element as a hollow body be used.
  • the welding connector is connected to several Setting the hollow chamber profile fixed or spread.
  • the welding corner connector it is advantageous to the welding corner connector in such a way that the expansion element four actuating arms each associated with one of four end sections are.
  • the end sections become even over 360 ° arranged distributed, as well as the actuating arms, so that a clamping action in four of each other accordingly results in different directions. That means one optimal clamping of the welded corner connector at comparatively low design effort.
  • the welding connector in the region of its end sections be specially adapted. It is particularly advantageous if provided the end portions of the male body with ramp surfaces are, with increasing angle of rotation of the actuating arms of the expansion element increasingly protrude into the outer circumferential path. With the ramp surfaces, the contact forces between the end sections and the hollow chamber profile for a predetermined spreading element in relation to the operating rotation angle be determined. Conveniently, the ramp surfaces It is designed 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 casserole. Accordingly become the maximum clamping forces with smaller tolerances already reached when the spreader is not yet reached the complete theoretically possible rotation angle Has. In any case, it can be ensured that the required clamping forces are achieved by twisting of the expansion element used a torque wrench becomes.
  • the ramp surfaces are thin-walled project from the end sections and with their end edges the end sections are supported.
  • the ramp surfaces can be formed according to the clamping conditions, without doing so To increase the mass of the weld connector about the charge.
  • the end support of the ramp surfaces ensures the required stabilization and can thus be formed that the introduced clamping forces in the desired direction act on the end sections.
  • the welding connector can be formed so that the ramp surfaces of a rectangular male body respectively associated with one of the side surfaces, wherein the narrow Side surfaces associated with each run-up surfaces of one on the half long side tuned longer operating arm and the ramp surfaces associated with the wide side surfaces each from one to half the narrow side tuned shorter actuating arm are acted upon.
  • the spreader remains with its axis coaxial or parallel to the axis Hollow chamber profile or to the male body. A canting of the Spreizelements is avoided and resulting impairments the clamping of the end sections in the hollow chamber profile do not occur.
  • the welding connector in such a way that the ramp surfaces in the direction of the pad the connector axis are inclined. With the help of inclination the ramp surfaces can be achieved that the expansion element disability-free can be inserted and play sitting in the male body by the spring action of the end portions is exploited for this.
  • the spreader is not unintentionally reversed. If this is the case Forms of expansion element and male body or ramp surfaces can not be achieved without further ado, it is appropriate form the welding connector such that at least a ramp surface and / or at least one actuating arm ramp surface provided with friction increasing means is.
