  • connection between Frame structure 7 and heat-insulating material 14 is next to it the aforementioned shape in the area of the connection between Frame structure and heat-insulating material possible through Application of adhesive material in addition to the connection consolidate.
  • the shape, the connection in addition secures in the connection area between frame structure 7 and Foam material 14 can, as shown in Fig. 7, also from a Interlocking on the frame structure and a corresponding one There are teeth on the insulating material. This increases the liability between insulating material and Frame structure 7 and thus ensures a form-fitting Connection.
  • connection profile 12 shown in FIGS. 5, 6 and 7 to the Holding contour of a metal profile is on both sides of the insulation strip 2 as one piece Swallowtail trained in a corresponding Cutout on a holding contour of a metal profile intervenes.
  • Shapes according to the holding contour of the metal profile conceivable.
  • FIGS. 5, 6 and 7 shown in FIGS Insulation strips have an interrupted frame structure 7. Because no direct connection through the Frame structure exists, and the heat flow only through that Insulating material takes place, the heat flow in the Insulation strip severely limited. Thus, good ones Thermal insulation properties achieved.
  • FIG. 5 8 Another embodiment, that of FIG. 5 8 is shown.
  • the insulation material 14 is here glued between two parts of the frame structure 7. in the Contrary to the previously shown embodiments, closes the thermal insulation material between the frame structure 7 is glued, but not flush with the frame structure 7 and in particular from the longitudinal walls 4, but is laterally extended.
  • this can be advantageous because higher thermal insulation is achieved.
  • the Heat exchange by radiation hampers, which also leads to Achieving good insulation properties is exploited.
  • a Reduction of the convection space also ensures improved insulation properties.
  • Figures 9, 10 and 11 show various aspects of another Embodiment of the present invention.
  • the frame structure 7 from an im essentially continuous longitudinal wall 4 and two on their End arranged transverse webs 6 formed. These crossbars serve to absorb the insulating material and cause it Desired and required stabilization of the insulation strip.
  • the insulating material 14 is on the side of the longitudinal wall on both Pages arranged, symmetrical in the case of Figure 9, in the case of Figures 10 and 11 asymmetrical.
  • the one shown in Fig. 9 Longitudinal wall 4 has interruptions 13, which are in Fig. 10 and 11 longitudinal walls 4 not shown.
  • connection profile 12 to the holding contour of a metal profile (not shown) each a dovetail that is centered on the outside the cross sections 6 is attached.
  • the Interruptions in the longitudinal wall have the advantage that when Foaming the insulation material through the Recesses extends in the longitudinal wall and thus the two Areas of the insulation material on both sides of the longitudinal walls are formed from a single piece. This increases the mechanical stability of the insulation material.
  • the insulating material is attached to the side of the longitudinal wall 4.
  • This insulating material 14, for. B. foam material can either be glued to the frame structure 7, the in 9, 10 and 11 shown cross profiles an arcuate Have shape and thus hold the foam mass 14 in addition and secure against loosening in relation to the frame structure.
  • the insulating material can also be similar to that in FIG. 5 described, introduced in that first a closed hollow profile is formed, in which the Foam material 14 is poured, and then the outer Longitudinal walls are milled away in order to achieve the final shape come, which is shown in Fig. 9.
  • Figures 10 and 11 show Similar to FIG. 8, an insulation strip 2, in which at least one Part of the heat insulating material 14, which in connection with stands the frame structure 7, protrudes from this.
  • This Projection of the insulating material 14 can over the entire length of the Insulation strip may be present, or only over partial areas. As mentioned above, it serves as far as there is space allow in the overall arrangement, the additional insulation by reducing the convection space and as Radiation barrier.
  • the insulation strip 2 in one of those shown in FIGS. 9, 10 and 11 Embodiments offers good insulation and Thermal insulation properties because the frame structure is thin can be formed because the heat-insulating material 14 a Absorbs part of the mechanical load. Thin profiles ensure low heat conduction and therefore good Thermal insulation properties.
  • FIGS. 12, 15, 16th and 17 are further embodiments of the present invention shown. These embodiments common that, as from the side views (Fig. 12, 15, 16th and 17) can be seen the insulation strip along its Cross-sections changing in the longitudinal direction.
  • at least one of the longitudinal walls 4 of the Insulation strip 2 is provided with recesses 15, which to the Leads to cross-sectional changes. Otherwise these recesses reduce closed hollow profile of this embodiment additionally the heat flow.
  • the longitudinal wall can only be in one limited area serve as a thermal bridge.
  • the course of the Heat flow is indicated by an arrow Q in FIGS. 12, 15, 16 and 17 indicated.
  • the recesses 15 in the longitudinal wall 4 of the Insulation strips can have different shapes (circle, rectangle, Triangle etc.).
  • FIGS. 13 and 14 Cuts through the insulation strip according to FIG. 12 are shown in FIGS. 13 and 14.
  • 13 corresponds to a section the position marked with A-A from FIG. 12, FIG. 14 a cut at the point marked B-B.
  • the insulation strip additionally an area protruding from the main profile having.
  • this is not absolutely necessary but a flush formation of the foam filling 14 in the Insulation strip 2, the cutouts in at least one of their Longitudinal walls 4 is conceivable and in Fig. 18th shown.
  • FIGS. 19 and 20 Another essential feature is shown in FIGS. 19 and 20 shown.
  • the illustrated embodiment of the invention is based on the embodiment shown in FIG. 2.
  • Insulated material 18 attached to the insulation strip 2.
  • this additional insulation material 18 is generally stuck on.
  • a bracket 19 for this Additional insulation in the frame structure should be integrated in the form of projections that additionally increase the radiation area, as shown in Fig. 20, the additional insulation area without further guidance be glued on.
  • Attaching one Holding structure 19 offers an additional security against slipping of the insulating material the advantage that Insulation material can also be clamped in this holding area can, or the holding area with the insulating material can form-fit connection.
  • the essential aspect of the insulation strip according to the invention lies in that, since it was recognized that the thermal insulation material absorbs part of the mechanical load that Frame structure of the insulation strip may be thin-walled can or in some areas recesses or May have interruptions. This leads to the fact that Thermal insulation properties of the insulation strip can be improved without to forego mechanical strength properties have to.
  • the frame structure of the insulation strip is not open certain embodiments limited, but all conceivable Frame structures can be combined with thermal insulation Material that is attached so that it is part of the absorbs mechanical stress.
