Definitions

  • the invention relates to a composite profile bar, in particular for casement frames, window frames, facades with an inner and an outer partial profile bar, both of which are connected to one another by spaced-apart connectors made of a heat-insulating material, the connectors being designed as two web-like intermediate pieces hooked into grooves in the partial profile bars are which are pushed apart by at least one wedge-shaped section inserted between them and braced in the grooves of the section bars and in which section section bar the heat-insulating air chambers are expediently covered by strips or strips.
  • a known composite profile rod of this type (FR-PS 23 20 412) at least one wedge piece is also inserted between two connectors or intermediate pieces in the longitudinal direction. It is a simple wedge connection with only one effective wedge surface. Due to thermal tensions and mechanical twists, the wedged pieces can move against each other and thus loosen the connection.
  • the known profile rod provides a toothing on the wedge surfaces. When driving in the wedge-shaped sections, especially when applying greater forces, this toothing will shear off easily; because the size and strength of these teeth is very limited, unless you want to do without a stepless adjustment of the spline connection.
  • the known composite profile rod is therefore not suitable for absorbing large forces.
  • the invention is therefore based on the object of improving a composite profile rod of the type mentioned in such a way that the wedge connection between the intermediate pieces can withstand even the highest thermal and mechanical influences and can also absorb greater forces.
  • a composite profile bar of the type mentioned according to the invention is characterized in that the intermediate pieces and the wedge-shaped section are designed in the cross section of the composite profile bar as a step wedge with at least one wedge step, the wedge step rising obliquely in the longitudinal views of the intermediate pieces and the section to allow the connectors to be clamped in the grooves of the partial profiled bars by moving the partial section along the wedge step.
  • the step wedge formed by the intermediate pieces and the section with at least one wedge step causes a transverse movement during longitudinal displacement and thereby wedges all the wedge surfaces to form a fixed wedge connection.
  • FIG. 1 shows a cross section through a composite profile rod in the region of the connector, of which FIG. 2 shows a section along line 11-11 and FIG. 3 shows a view according to arrow I.
  • Fig. 4 shows the connector alone in side view
  • Fig. 5 shows a section along the line III-III of Fig. 4.
  • FIGS. 7 to 10 illustrate the connector in mutually associated cracks before and after tensioning.
  • 11 shows a section through the composite profile bar with a modified connecting piece
  • FIG. 12 shows a side view thereof
  • FIGS. 13 and 14 illustrate the individual parts in an exploded perspective view.
  • FIG. 15 the connector is shown in side view in the clamped state, for which purpose Fig. 16 shows a longitudinal view. 17 and 18 show the same connector in the unstressed state in mutually associated cracks.
  • An embodiment with a double wedge step is shown in FIGS. 19 and 20, the left half of FIG. 20 representing a section in the rear part and the right half in the front part.
  • the composite profile rod preferably consists of light-metal extruded partial profile rods 17, 18, which have undercut grooves on the facing surfaces for anchoring the intermediate pieces 1, 2 of connectors.
  • these connectors also consist of a partial piece 3, which is driven between the intermediate pieces 1, 2 and presses them into the grooves of the partial profiled bars 17, 18, thereby a dimensionally stable connection even without additional fasteners such as adhesives, rivets, screw connections and the like. is guaranteed.
  • the space between the partial profile bars 17, 18 is then closed by cover profiles 19, 20 made of heat-insulating material.
  • the section 3 and the intermediate pieces 1, 2 are fixed against one another in the non-clamped state by co-located dowel pins 11, these dowel pins being sheared off or broken off when the individual parts are shifted and thus braced.
  • the length and width of the individual sections of the connector is chosen so large that there is complete coverage of the wedge surfaces in different positions after tensioning (FIGS. 7 to 10) and thus a favorable pressure distribution and uniform pressure prevent the distortions.
  • 7 and 8 show intermediate pieces 1, and the section 3 in a weakly tensioned state, while FIGS. 9, 10 illustrate the strongly tensioned state.
  • the shift can be carried out by a device with a metered force in order to avoid excessive deformations which could lead to deviations from the tolerance limits.
  • the invention is not restricted to the exemplary embodiments shown.
  • Fig. 11 to 18 two extruded aluminum profile bars 17, 18 are mechanically fixed together by a three-part connector made of heat-insulating material.
  • the connector consists of the two intermediate pieces 1 and 2, which are pressed into the grooves of the section bars 17, 18 by a wedge-shaped section 3. Since the connectors are arranged at intervals, the grooves or cavities between them are closed by cover profiles 19, 20.
  • the two web-like intermediate pieces 1, 2 are secured with additionally attached, interlocking claws 21, 22 against the fact that the two web-like intermediate pieces, seen in the longitudinal axis of the profile, can move against one another.
  • the invention is not limited to the illustrated embodiment, but single or multiple toothing is possible with straight tooth flanks or curved or shaped tooth flanks, which additionally form a cohesion of the parts before insertion into the profile grooves.
  • circular-cylindrical tooth flanks are provided, which engage in one another in a form-fitting manner, so that not only a displacement in the longitudinal direction but also transversely to it is prevented, so that the intermediate pieces 1, 2 can only move in the direction of the grooves of the partial profiles 17, 18 .
  • a wedge step 25 is arranged on a rib 24 parallel to the wedge step 9 'on the section 3.
  • This rib 24 engages in a groove 23 of the intermediate piece 1 or 2 and also has a lower wedge-shaped guide surface 26.
  • This further toothing not only ensures better cohesion of the parts of the connector before or during insertion, but also a larger contact area and thus achieves lower specific surface pressure, which in turn leads to better load distribution and thus less deformation or long-term creep behavior.
  • Rib 24 or groove 23 are arranged approximately at the height of the dowel pins 11.
