Insulating bridge with Folienisolierkörper

description

The present invention relates to an insulating web for connecting two profile parts of a window, door or façade element or a composite profile having at least one such insulating web.

The inner profile and the outer profile of a thermally-separated composite profile, such as, e.g. an aluminum composite profile, for window, door or facade elements are connected by one or more insulating bars. The inner and outer profile parts often have different temperatures. In addition to heat conduction through the insulating bars, heat is also transmitted or conducted by convection and by radiation between the profiles. To minimize the heat conduction of the cavity between the profiles can be divided into several chambers or filled with foam material. The composite profile can also be painted for visual reasons.

From DE 195 28 498 Cl a composite profile is described which has an insulating core. The insulating core has at least two insulating ribs, which connect the metal profiles of the composite profile with each other and form a chamber on. At the insulating webs transverse webs are provided, each projecting into the chamber interior. In the assembled state, the transverse webs overlap one another flat, so that gas-tight sub-chambers are formed between the insulating webs.

DE 42 03 758 AI also shows a composite profile consisting of two metal profile parts, which are interconnected by Kunststoffisolierstege. It is further described that the space defined by the metal profile parts and the Kunststoffisolierstege with a heat-insulating material which is at least a flexible garland, which conforms to the metal profile parts, is filled.

From DE 198 43 742 AI a plastic profile is known in which at least one of the stiffening serving profile core, which has a honeycomb-shaped cross-sectional structure is provided between two hollow profile elements. From DE 28 09 1 19 a thermally insulated composite profile is known, in which insulating intermediate layers, the axially perpendicular or parallel to the profile parts extending air chambers are arranged between the profile parts.

From DE 202 01 670 Ul a multi-chamber profile made of plastic is known, are provided in which extending within an outer shell in the longitudinal extent of the profile hollow chambers with a polygonal structure with a homogeneous structure with equal size cells.

From WO 02/057582 AI profile parts are known, which are connected by a thin-walled network forming hollow chambers between the profile parts.

From DE 30 42 838 AI a composite profile is known, in which intermediate walls are provided for forming chambers in the intermediate space between the profile parts.

EP 0 764 756 A1 discloses composite profiles in which two profile parts are connected to one another by two connecting webs, wherein the cavity formed by the profile parts and connecting webs is subdivided by an intermediate wall which has a V-shape.

From DE 195 12 317 C1 a precursor for the production of metal / plastic composite profile bars is known, which consist of a metallic inner profile bar, a parallel to the inner profile rod metallic outer profile bar and at least two cooperating distance profile rods made of thermoplastic material, the form-fitting and / or adhesive and longitudinal chamber forming with the inner profile bar and the outer profile bar are united. The longitudinal chamber forming spacer profile rods are connected by at least one longitudinal connecting element to a spacer profile rod pair. The spacer profile bars and the connecting elements have a rectangular quadrangular functional outline when installed in cross-section. The spacer profile rods of the Distanzprofilstab- pairs are deformed cross-section with deformation of the connecting element for transport and storage to the intermediate product. A hollow profile made of plastic is known from EP 0 828 052 A2, in which an inner space of the hollow profile enclosed by outer walls is subdivided into chambers by support webs and a chamber at a distance from the longitudinal side wall and parallel to the longitudinal side wall is provided in the interior or in at least one chamber associated with a longitudinal side wall extending barrier film is arranged.

From AT 372 491 a composite profile is known in which a thin-walled non-bearing PVC fabric profile is used in an air chamber between two insulating webs to increase the thermal insulation, which divides the air chamber into two or more longitudinal sub-chambers.

It is an object of the present invention to provide an insulating web for a composite profile for window, door or facade elements for connecting two profile parts of the composite profile, which has improved thermal insulation, and a composite profile with such an insulating web.

This object is achieved by an insulating web according to claim 1 or a composite profile according to claim 14.

Further developments of the invention are specified in the dependent claims.

It is given an insulating bar for a composite profile with an insulator attached thereto. The insulating body can be made regardless of the insulating bar in a simple manner and attached to this.

The insulating body may have different shapes, which allow easy adaptation to the profile parts used and the desired insulation.

The insulating body can be made separately from the Isolierstegprofil. The insulator can therefore be made in a unit size and cut to size prior to attachment to the insulating web profile. It is a modular insulating bridge system allows for the same Isolierstegprofilen different insulator heights and widths possible.

The insulating body may be formed of the same material as the Isolierstegprofil, so that the entire Isolierstegprofil can be recycled or recycled without further material separation steps and the like.

By using plastic film material, the insulating body can be made extremely light. The film material allows a simple and quick production of the insulating body by welding or gluing. The lightweight film material makes it possible to form the insulating body self-supporting and structurally rigid. This allows the Isolierstegprofil can be formed with a smaller wall thickness than conventional Isolierstegprofile the same load to be absorbed, since a portion of the load can be absorbed by the preferably structurally rigid insulating web.

The insulating web profile can be assembled and / or calibrated separately from the insulating body. As a result, an insulating web profile can be created with low manufacturing tolerances. Advantageously, the insulating web profile is first made of a suitable material as a profiled part with a constant cross-section, e.g. manufactured by extrusion. Furthermore, the insulating body is preferably formed of sheet material by means of welding or gluing. Subsequently, both parts are assembled as needed and combined or attached to each other.

1 shows a composite profile 1 (eg a window frame) with a first profile part 2 in the form of a window frame profile outer part and a second profile part 4 in the form of a window frame. terrahmenprofilinnenteils. The first profile part 2 and the second profile part 4 each extend in the longitudinal direction Z. The two profile parts 2, 4 are located in the height direction Y, which is perpendicular to the longitudinal direction Z, opposite. The profile parts 2, 4 are connected to each other by two insulating webs 6, which extend in the height direction Y between the profile parts 2, 4 and in the longitudinal direction Z. By the profile parts 2, 4 and the insulating webs 6, a cavity 100 is formed, which extends in the longitudinal direction Z. The insulating webs 6 have a first height hl in the height direction Y on. The cavity 100 in this embodiment also extends in the height direction Y with the first height hl. In the transverse direction Y, the cavity 100 is limited by the first distance a1 of the insulating ribs 6 from each other.

The first profile part 2 and the second profile part 4 may have different temperatures or be exposed to different temperatures. A heat conduction or heat transfer between the profile parts therefore takes place mainly in the height direction Y. The heat conduction takes place, as described above, on the one hand directly through the insulating webs 6 and on the other hand by convection and radiation through the cavity 100th

One of the insulating webs 6 according to a first embodiment, which connects the profile parts 2, 4 of Fig. 1 together, is shown in Fig. 2 in an enlarged view. The insulating web 6 has an insulating web profile 8, which extends in the longitudinal direction Z and is adapted for fixed connection to the first profile part 2 and the second profile part 4 for connecting the same in the height direction Y. The Isolierstegprofil 8 has a longitudinal direction Z constant cross-sectional shape. At the edges in the height direction Y, the insulating web profile 8 in each case has roll-on projections in the form of rolling-in strips 8a. The Einrollleisten 8a have a dovetail shape in cross-section perpendicular to the longitudinal direction Z. The Einrollleisten 8a are each connected via an angled (cranked) portion 8b with a central portion 8c of the Isolierstegprofils 8. The central portion 8c extends perpendicular to a transverse direction X, which is perpendicular to the longitudinal direction Z and the height direction Y, between the angled portions 8b. The relevant for the heat conduction middle section 8c has a first thickness (thickness) dl in the transverse direction X. The insulating web profile 6, and thus the insulating web 6 has the first height hl in the height direction Y. The middle section 8c has a second height h2 in the height direction Y. As can be seen from Fig. 1, the profile parts 2, 4 recordings 2a, 4a for rolling the Einrollleisten 8a of the insulating webs 6. The recordings 2a, 4a are each bounded by a roll-in hammer 2b, 4b and a roller bearing 2c, 4c. The recordings 2a, 4a of the profile parts 2, 4 have a complementary dovetail shape in the rolled-up state. The insulating bars 6 are therefore connected in a known manner with the profile parts 2, 4 by rolling. The profile parts 2, 4 and the insulating webs 6 define a closed in cross-section perpendicular to the longitudinal direction Z cavity 100th

A Isolierstegprofil 8 according to the first embodiment further has an inner side 8d, which faces the cavity 100 and the opposite Isolierstegprofil 8. On the inside 8d of the insulating web profile 8, an insulating body 10 is attached or formed. The insulating body 10 extends in the longitudinal direction Z with a constant cross section perpendicular to the longitudinal direction Z. The insulating body 10 extends in the transverse direction X away from the inner side 8d with a second width b2. That is, the insulator protrudes into the cavity 100 having the second width b2. The insulating body 10 has a third height h3 in the height direction Y. Preferably, the third height h3 is smaller than the first height hl of the insulating strip profile 8, more preferably smaller than the second height h2 of the middle section 8c. The third height h3 is therefore preferably selected so that the insulating body 10 does not touch the profile parts 1, 2 in the assembled state of the composite profile.

3 shows an enlarged cross-sectional view perpendicular to the longitudinal direction Z of such an insulating body 10. The insulating body 10 has a first base wall 12 (first insulating body wall) and a second base wall 14 (second insulating body wall). The base walls 12, 14 are planar and extend perpendicular to the height direction Y (ie in the transverse direction X) with the second width b2 and in the longitudinal direction Z with a constant cross section perpendicular to the longitudinal direction Z. The first base wall 12 is at a second distance a2 is arranged in the height direction Y parallel to the second base wall 14. The base walls have a first thickness (wall thickness) dl.

On one of the inner side 8d of the Isolierstegprofils 8 facing edge of the first base wall 12, the first base wall 12 has a first angled mounting portion 12a. The first angled mounting portion 12 a extends perpendicular to the transverse direction X with a constant cross section perpendicular to the longitudinal direction Z in the longitudinal direction Z. The The first angled fastening region 12a of the first base wall 12 extends with a fourth height h4 in the height direction Y from the side of the first base wall 12 facing away from the second base wall 14.

Accordingly, the second base wall 14 has a second angled mounting region 14a. The second angled mounting portion 14a is also formed on the inner side 8d of the Isolierstegprofils 8 facing edge of the second base wall 14 and extends perpendicular to the transverse direction X with a constant cross-section perpendicular to the longitudinal direction Z in the longitudinal direction Z. The second angled connecting portion 14a extends on the side facing away from the first base wall 12 of the second base wall 14 with a fifth height h5 in the height direction Y.

Between the first base wall 12 and the second base wall 14, a first partition wall 16 is formed or arranged. The first partition wall 16 extends in the longitudinal direction Z with a constant cross section perpendicular to the longitudinal direction Z. The first partition wall 16 is alternately connected in its transverse direction X with the first base wall 12 and the second base wall 14. That is, in this embodiment, the first partition wall 16 extends "zigzag" between the first base wall 12 and the second base wall 14 in the transverse direction X. In other words, the partition wall 16 is over a plurality (here five) first connection areas 18 with the first one Each adjacent first connecting portions 18 have a third distance a3 to each other in the transverse direction X. The transverse outer portions 18 are near or on the respective edge of the first base wall 12 in the transverse direction X. Further, the partition is 16 are connected to the second base wall 14 through a plurality of (here four) second connection portions 22 which are offset in the transverse direction X between the first connection portions 18 but offset in the height direction Y due to the arrangement on the second base wall 14. Also, the second connection portions 22 are arrange with the third distance a3 in the transverse direction X to each other et, wherein each second connection region 22 has a distance (a3) / 2 in the transverse direction X to the respectively adjacent first connection region 18. Each of the first connection portions 18 and the second connection portion 22 extends straight in the longitudinal direction Z. Due to the described arrangement, between each two adjacent to the first base wall 12 first connecting portions 18 by the first base wall 12 and the first partition wall 16, a first cavity 20 is limited.

Furthermore, between each two adjacent to the second base wall 14 second connecting portions 22 through the second base wall 14 and the first partition wall 16, a second cavity 24 is defined.

Depending on the number of connection areas, a plurality of first and second cavities 20, 24 can thus be formed.

Both the first cavities 20 and the second cavities 24 extend in the longitudinal direction Z with a constant cross section perpendicular to the longitudinal direction Z. The cavities have in this embodiment, seen in cross section to the longitudinal direction Z, the shape of an isosceles triangle, in which the base is formed respectively by a portion of the base wall 12, 14 between two adjacent connection portions 18, 22 having a length in the transverse direction X corresponding to the third distance a3, and the equilateral legs are formed by the partition wall 16, respectively. The height of this equilateral triangle corresponds essentially to the second distance a2 between the first base wall 12 and the second base wall 14 in the height direction Y. An angle α between the partition wall 16 or the legs and the base wall 12, 14 is approximately 60 ° here so that an equilateral triangle is formed.

At the outer edges in the transverse direction X of the insulating body 10 thus assembled, a further end cavity 26, 28 is formed due to the "zigzag" shape of the partition, which corresponds to half of one of the first or second cavities 20,24.

Furthermore, in each case a cover or a closure cap (not shown) can optionally be placed on the end faces of the insulating body 10 in the longitudinal direction Z, which serves to close the cavities 20, 24. This can prevent that, for example, in a pretreatment for powder coating of the insulating bars in a bath liquid in the cavities 20, 24 penetrates. The base walls 12, 14 are made of a first film of a first plastic film material or are a first film of the first film material and have a first thickness dl. The partition wall 16 is formed of a second film of a second plastic film material or a second film of the second film material, which corresponds to the first in this embodiment, and has a second thickness d2. The first connection regions 18 and second connection regions 20 in this embodiment are welded joints, which are preferably produced by laser welding. Here, the base walls 12, 14 and / or the partition wall 8 wholly or partially of laser light absorbing and / or laser light permeable or in transparent and / or transparent plastic material can be prepared so that a welding by means of a laser by melting the partition wall 16 and / or the base walls 12, 14 can be made. The welding is preferably continuous in the longitudinal direction. But it is also possible to provide these only in sections.

The insulating body 10 formed as described is designed to be self-supporting and structurally rigid due to the described structure of base walls 12, 14, which are connected to one another by the "zigzag" -shaped partition 18. The individual cavities or connecting areas are preferably made airtight.

The insulating body 10 is fixed to the inner side 8d of the insulating rib profile 8 by the first fixing portion 12a and the second fixing portion 14a. The second end cavity 28 of the insulating body 10 in the transverse direction X is thus bounded by the second base wall 22, the partition wall 16 and the Isolierstegprofil 8 and extends in the longitudinal direction Z with a constant cross section perpendicular to the longitudinal direction Z. The shape of the second end cavity 28 corresponds the mirrored at a plane perpendicular to the transverse direction X shape of the first end cavity 26. The mounting portions 12 a, 14 a are also preferably connected by welding to the Isolierstegprofil 8. Again, welding may preferably be accomplished by forming the attachment regions 12a, 14a of light-absorbing or non-absorbent plastic film material.

Through the first cavities 20, the second cavities 24 and the end cavities 26, 28, an insulating space 32 with a rectangular cross section is formed between the base walls transversely to the longitudinal direction Z, which in the longitudinal direction Z with constant transverse section perpendicular to the longitudinal direction Z and having a fifth height in the height direction Y and the second width b2 in the transverse direction X. The fifth height corresponds to the second distance a2.

As shown in Fig. 1, the composite profile 1 is formed from the profile parts 2, 4 and two of the insulating webs 6 described above. The insulating webs 6 are arranged so that the insulating body 10 are arranged in the defined by the profile parts 2, 4 and the Isolierstegprofile 8 cavity 100.

In this embodiment, the insulating webs 6 are arranged in mirror image with respect to a plane perpendicular to the transverse direction X extending plane of symmetry. That is, the insulators 10 are arranged in the height direction Y at the same height. The maximum second width of the insulating body is therefore al / 2 in this embodiment.

Due to the arrangement of the insulating body 6, which each form one of the above-described isolation spaces 32, in the cavity 100, a heat radiation transmission and heat transfer by convection within the cavity 100 in particular in the height direction Y can be prevented or reduced. Furthermore, a heat transfer within each isolation space 32 or through each isolation space 32 is reduced or prevented, since each isolation space 32 itself is divided by the partition wall 16 into individual hollow chambers 20, 24, 26, 28. The insulating body 10 therefore forms an insulating wall, in particular in the height direction, in the cavity 100. Since the insulating body 10 is formed so that it is not in contact with the profile parts 2, 4 and is fastened exclusively to the central region 8c of the Isolierstegprofils 8, no direct heat conduction between the profile parts 2, 4 takes place through the insulating body 10 therethrough.

The insulating body 10 is formed by the described arrangement preferably self-supporting and structurally stiff at the same time very light weight. Thus, the Isolierstegprofil 6 may be formed with a smaller first width bl in the transverse direction X, since on the one hand, the weight of the insulator is very low and on the other, the structural rigidity of the insulating body 10 contributes to stiffen the Isolierstegprofil 8. By producing the insulating body 10 alone made of plastic film, the insulator can be made very inexpensively and easily. Furthermore, the plastic film material of the insulating body 10 may correspond to the first plastic material of the insulating web profile 8, so that the insulating web 6 is made entirely of one and the same material.

As a result, the insulating bar can be recycled or utilized "in one piece" without the need for further separation or sorting steps.

Hereinafter, a method for producing the above-described insulating bar or composite profile according to the first embodiment will be described.

The insulating web profile 8 is preferably produced by extrusion with predetermined, desired dimensions and assembled or cut to length. Separately, the insulator 10 can be manufactured. For this purpose, conventional or special plastic films with a desired length are used. By way of example, a first film which forms the partition wall 16 is inserted in a "zigzag" shape and welded to the first base wall 12 in the first connection regions 18. The "zigzag" shape is formed in accordance with the desired width and height of the insulating body. Subsequently, the second base wall 14 is welded to the partition wall 16 in the second connection regions 22. The "insulating mat" thus obtained is then sawed off or cut to the desired width in the transverse direction X so that at least one end coincides with a first or second connecting region 18, 22. This achieves the result that the dividing wall 16 on the insulating web profile 8 opposite end of the insulating body is not cut off between the base walls 12, 14 and is "loose". The desired width is made up of the second width b2 of the trainees insulating body 10 and the third and fourth height h3, h4 of the mounting portions 12a, 14a together. Subsequently, the attachment areas 12a, 14a of the base walls 12, 14 are optionally angled. This can be done for example by kinking with simultaneous heating. Furthermore, the "loose" remainder of the dividing wall 16 existing between the fastening areas 12a, 14a is cut off as far as the closest connecting area 18, 22.

Subsequently, the thus formed, self-supporting and structurally rigid insulating body 10 by means of the mounting portions 112a, 14a on the insulating body 5 by welding or Glued attached. In a last step, the insulating web thus formed is inserted into the receptacles 2 a, 4 a formed in the profile parts 1, 2. The insulating bars 6 are then connected by rolling the rolling hammer 2b fixed to the profile parts 2, 4 for producing the composite profile according to the first embodiment.

In the following, with reference to FIGS. 4 to 18, composite profiles or insulating bars according to a second to fifteenth embodiment will be described. Components and sizes corresponding to those of the first embodiment will be hereinafter referred to by the same reference numerals and will not be described again. That Essentially, the differences from the first or between the embodiments will be described.

Figures 4 and 5 show an insulating web 6 according to a second embodiment. The insulating bar 6 according to the second embodiment has an insulating body 10, which has three Isolierkörperwände. The insulating body walls lying in the vertical direction are referred to as base walls 12, 14, while the further insulating body wall arranged between them is referred to as intermediate wall 34. The base walls 12, 14 are, as in the first embodiment, arranged at a first distance al in the height direction Y. The intermediate wall 34 extends in the longitudinal direction Z parallel to the base walls 12, 14 with a constant cross section perpendicular to the longitudinal direction Z. The intermediate wall 34 has a third thickness d3, which corresponds in this embodiment, the first thickness dl of the base walls. The intermediate wall 34 is arranged in the vertical direction Y in the middle in this embodiment with a fourth distance a4 to the first base wall 12 and a fifth distance a5 to the second base wall 14 between the base walls 12, 14. The intermediate wall 34 in this embodiment has a width which corresponds to the width of the base walls 12, 14 in the first embodiment.

The intermediate wall 34 divides the insulating space 32 of the first embodiment delimited by the base walls 12, 14 into two partial insulating spaces 32a and 32b (see FIG. 4). The first partial insulating space 32 a corresponds to the insulating space 32 of the first embodiment and is formed between the first base wall 12 and the intermediate wall 34. The second partial insulation space 32 b is formed between the second base wall 14 and the intermediate wall 34. The height of the Teilisolierräume 32a, 32b corresponds to the distance a4, a5 of the respective walls. Between the first base wall 12 and the intermediate wall 34, ie in the first Teilisolierraum 32 a, a first partition wall 16 a is formed, which is connected according to the partition wall 16 of the first embodiment via a plurality of first connecting portions 18 a with the base wall 12 and a plurality of second connecting portions 22 a with the intermediate wall 34 is connected. The first connection regions 18a correspond to those in the first embodiment. The second connection portions 22a on the intermediate wall 34 are formed straight in the longitudinal direction Z like the second connection portions 22 of the first embodiment. That is, between the first base wall 12 and the intermediate wall 34, the first partition wall 16a is alternately connected to the first base wall 12 and the intermediate wall 34 via first and second connection portions 18a, 22a so that the first partition wall 16a has a zigzag shape and in FIG the transverse direction X runs.

By the first partition 16a, the base wall 12 and the intermediate wall 34 cavities 20, 24 are formed, which according to the first embodiment in cross section perpendicular to the longitudinal direction Z have a triangular shape and in the longitudinal direction Z with a constant cross section perpendicular to the longitudinal direction Z and extend in the same.

Between the intermediate wall 34 and the second base wall 14, a second partition 16 b is arranged or formed. The second partition wall 16b is arranged between the intermediate wall 34 and the second base wall 14 such that the intermediate wall 34 forms a plane of symmetry with respect to the first partition wall 16a. That is, the second partition wall 16b is connected to the second base wall 14 by first connection portions 18a in the transverse direction X at the same position as the first partition wall 16a is connected to the first base wall 12. Accordingly, the second partition wall 16b is also connected to the partition wall 34 through second connection portions 22a at the same position in the transverse direction X (only just on the side facing away from the first base wall 12 side of the intermediate wall 34) as the first partition 16a connected.

According to the first embodiment, at the front ends, ie at the ends of the insulating body 10 in the longitudinal direction Z such cover (not shown) may be placed, that the cavities 20, 24 are closed. Through the first base wall 12, the first partition wall 16a, the intermediate wall 34, the second partition wall 16b and the second base wall 14, an insulating body 10 is formed in the same order in the height direction Y. As described above, the insulating body 10 is divided into the first partial insulating space 32a extending between the first base wall 12 and the intermediate wall 34 and the second partial insulating space 32b extending between the intermediate wall 34 and the second base wall 14. The Teilisolierräume 32 a, 32 b are each divided by a partition 16 a, 16 b in the cavities 20, 24 which extend perpendicular to the height direction Y.

The insulating body 10 thus formed, like that of the first embodiment, is self-supporting and structurally rigid.

In contrast to the insulating body 10 described in the first embodiment, the insulating body 10 according to the second embodiment may be formed higher in the height direction Y with a constant size of the cavities 20, 24. In this embodiment, the insulating body 10 has twice as many cavities 20, 24 as that of the first embodiment. Therefore, the insulating properties of the insulating body 10 are further improved.

Further, because of its greater extent in the height direction Y, the insulating body 10 is stiffer with respect to a bend in the height direction Y and the longitudinal direction Z, respectively. Thus, the insulating bar 6 can be formed wider in the transverse direction X as well. That is, the insulator 10 may have a larger second width b2 than the insulator 10 of the first embodiment.

The insulating body 10 is fastened to the inner side 8d of the insulating strip profile 8, preferably by welding, by means of the fastening regions 12a, 14a provided on the base walls 12, 14 in accordance with the first embodiment.

As described, in the second embodiment, the insulator 10 may have a larger width b2 in the transverse direction X. In the event that 1 Isolierstege 6 are to be used in the composite profile, in which the insulating body 10 are arranged at the same height in the height direction Y and in which the insulating body 10 have a second width b2, which is more than half of the first distance al between the insulating bars 6 carries, the insulator 10 must be placed on the insulating bars 6 in the vertical direction Y offset from each other so as not to touch or abut each other. In the embodiment shown in Fig. 4, the Isolierstege 6 are formed identical but automatically arranged during installation due to the opposite mounting position so that the insulating body overlap (in Fig. 4 right insulating bar 6 is 180 ° about an axis in the vertical direction Y. twisted to the left insulating bar 6).

Due to the overlap or overlap in the transverse direction X of the cavity 100 is filled despite relatively small third height h3 of the insulating body 10 itself with a high degree by the insulating body 10. Thereby, the heat conduction by heat radiation and convection is further reduced as compared with the first embodiment. As in the first embodiment, the insulating body 10 does not touch the profile parts 2, 4, so that no direct heat transfer takes place by heat conduction.

Hereinafter, a third embodiment will be described with reference to FIG. In the third embodiment, the insulating bar 6 has an insulating rib profile 8, on the inside of which 8d two of the insulating bodies 10 according to the first embodiment are fixed at different positions in the height direction Y. In a composite profile (not shown), which is assembled with such a Isoliersteg 6, the limited by the profile parts 2, 4 and the Isolierstegprofile 8 cavity is filled on the one hand by a plurality of insulator 10 and divided on the other in a plurality of sub-cavities between the insulators 8. As a result, the heat conduction through the cavity can be reduced. Alternatively, with such insulating webs 6, an "overlapping" arrangement, as shown in Fig. 4, are formed.

In the following, a composite profile 1 and an insulating bar 6 according to a fourth embodiment will be described with reference to FIGS. 7a and 7b. The insulating bar 6 according to the fourth embodiment is substantially an extension of the insulating bar 6 according to the second embodiment. In contrast to the insulating bar 6 according to the second embodiment (see FIG. 5), the insulating bar 6 according to the fourth embodiment has not only one but a plurality (here four) of partitions 34 (base walls that are sandwiched between two base walls lying in the height direction 12, 14 are formed), which according to the intermediate wall 34 in the second embodiment in the longitudinal direction tion Z parallel to the base walls 12, 14 extend. The sixth distance a6 between two adjacent intermediate walls 32 in this embodiment corresponds to the fourth or fifth distance a4, a5 between the base wall 12, 14 and the corresponding adjacent intermediate wall 34. As in the previous embodiments limit the outer base walls 12, 14 in the Height direction Y an insulating space 34. This isolation space 32 is divided by the partitions 34 in Teilisolierräume 32 a, 32 b, 32 c, which are limited in the height direction Y by the distance between adjacent partitions 32 and / or base walls 12, 14.

Between the base walls 12, 14 and in each case in the height direction Y adjacent intermediate wall 34 is formed as in the second embodiment, in each case a partition wall 16a, 16b according to the second embodiment. Between each adjacent partition walls 34 is also a partition wall 16c, which also according to the partition walls 16a, 16b zigzag-shaped extending between the intermediate walls and is connected via first and second connecting portions with them arranged. In the height direction Y adjacent partitions 16a, 16b, 16c are each arranged so that each arranged between them intermediate wall 34 represents a plane of symmetry. Also in this embodiment, between the base and intermediate walls respectively cavities 20, 24 through the partition walls 16a, 16b, 16c and the base walls 12, 14 and partitions 32 which extend in the longitudinal direction Z and the respective Teilisolierräume 32a, 32b , 32c subdivide, trained.

The insulating body 10 shown in Fig. 7a extends in the height direction Y almost over the entire second height h2 of the central portion 8c of the Isolierstegprofils 8 (see Fig. 2). For this reason, if, as shown in Fig. 7b, in a composite section 1, two insulating ribs 6 according to the fourth embodiment are used, the second width b2 of the insulating body 10 in the transverse direction X may not be greater than al / 2. Only in this way can it be ensured that the insulating webs 6 do not interfere with one another during the assembly of the composite profile, as shown in FIG. 7b.

Due to the large third height h3 of the insulating body in the height direction Y and the division by a plurality of intermediate walls 34 and partitions 16a, 16b, 16c, an insulating body 10 is provided, which is particularly stable, and when inserted into a composite profile as shown in FIG. 7b fills the cavity 100 to a high degree. As can be seen from Fig. 7b, although the second width b2 of the insulating body 10 on the insulating fin profile 6 according to the fourth embodiment is relatively short, by using the insulating ribs 6 according to the fourth embodiment, the cavity 100 is almost completely filled.

8 shows a fifth embodiment of an insulating bar 6. The insulating bar 6 according to the fifth embodiment has an insulating body 10 different from the insulating body 10 according to the second embodiment in that the first and second connecting areas 18a, 22a between the partition walls 16a , 16b are made wider in the transverse direction X. The respective connection portions 18a, 22a have a third width b3 in the transverse direction X in the insulating fin according to the fifth embodiment. Due to the greater width of the connecting regions 46, the angle α between the base walls 12, 14 or the intermediate wall 42 and the partition walls 161, 162 is increased at a constant number of connecting regions 18a, 22a with respect to the second embodiment. Alternatively, the number of connection regions 18 a, 22 a and thus of the cavities 20, 24 can be reduced.

Due to the widened design of the connecting regions 18a, 22a, the connection between the dividing walls 16a, 16b and the base walls 12, 14 or the intermediate wall 34 is reinforced. The insulating body can therefore be made more stable.

Fig. 9 shows an insulating bar 6 according to a sixth embodiment. In the sixth embodiment, the insulator 10 has two intermediate walls 34 between the two base walls 12, 14. Between the intermediate walls 34 and between the intermediate walls 34 and the corresponding base walls 12, 14, that is, in the Teilisolierräumen a partition 16d is arranged as well as in the previous embodiments. Each partition wall 16d is connected to the intermediate walls 34 and the base walls 12, 14 via first and second connection areas 18a, 22a, which extend in a straight line (only) in the transverse direction X, contrary to the previous embodiments. Thus, in this embodiment, the triangular cavities 20a, 24a defined in the transverse direction X by the base walls 12, 14 and partitions 34 and partitions 16d, respectively, extend across the second width b2 of the insulator of uniform cross section perpendicular to the transverse direction X. Partitions 16d thus extend in the transverse direction X with a constant cross-section perpendicular to the transverse direction X and in the longitudinal direction Z zigzag.

Also in the sixth embodiment, the cavities 20a, 24a formed in the insulator extend perpendicular to the height direction Y in which heat is transmitted through the insulator 6. Thus, insulating webs of this embodiment, with which a composite profile is formed (not shown) can effectively prevent heat conduction by convection or thermal radiation, since the longitudinal direction of the cavities 20a, 24s are formed perpendicular to the direction of heat conduction.

In Fig. 10, a seventh embodiment of the insulating bar 6 is shown. The insulating bar 6 according to the seventh embodiment is a combination of the insulating bar 6 according to the sixth embodiment and one of the insulating bars described above. In the insulating fin 6 according to the seventh embodiment, both cavities 20 a, 24 a are provided, which extend in the transverse direction X according to the sixth embodiment, as well as cavities 20, 24 are provided, which extend in the longitudinal direction Z.

The insulating bar 6 according to the seventh embodiment is particularly advantageous because it can be made particularly structurally stiff due to the "mixed" structure.

Fig. 11 shows an insulating bar 6 according to an eighth embodiment. In the insulating bar 6 according to the eighth embodiment, unlike the insulating bar 6 according to the fourth embodiment, the partition walls 16c are not disposed in all the partial insulating spaces 32c formed between the intermediate walls 34. Instead, foam or a foam body 36 is respectively formed in two of the partial insulation spaces 32c. Here are the Teilisolierräume 32c, in which the foam body 36 is formed in each case adjacent to a Teilisolierraum 32a, 32b, 32c disposed in which a partition wall 16a, 16b, 16c is arranged. The foam body 36 are each firmly glued or welded to the intermediate walls 34. Thus, it follows that intermediate walls 34, between which a foam body 36 is arranged, are held together only via the foam body 36 or connected to each other.

In the manufacture of an insulating bar 6 according to the eighth embodiment, the insulating body 10 is enclosed, the foam body completely formed and then with connected to the insulating bar 6. Also in this embodiment, the insulating body 10 is a self-supporting structurally rigid body.

Fig. 12 shows an insulating bar 6 according to a ninth embodiment. The insulator 6 according to the ninth embodiment differs from the insulator 6 according to the eighth embodiment in that the foamed bodies 36 serve as partitions. That is, in the eighth embodiment with the intermediate walls 34, which with a

Foam body 36 are connected, connected zigzag partition walls 16a, 16b, 16c are respectively directly connected to the foam body 36 and secured thereto. The attachment is also preferably by welding or gluing.

Both of the insulating bar 6 described in the eighth embodiment and the ninth embodiment have the advantage that they are particularly structurally rigid and have particularly good insulating properties, but at the same time are very light. By the foam body 36, the insulating property of Isolierköpers 10 is further improved.

Fig. 13 is a perspective view of a portion of a partition wall 16e as may be employed in each of the first to seventh embodiments. The partition wall 16e extends against the previously described partitions 16, 16a, 16b, 16c not with constant cross-section in the direction of the respective connecting portions 18, 18a, 22, 22a in the longitudinal direction Z and transverse direction X but points between three-dimensional input or Bulges or dents 38, which are alternately in the direction of the straight connection region 18, 18a, 22, 22a in or bulged. The dents 38 are in each case in the "legs" or portions of the partition 16e, which extend between two walls 12, 14, 34 and two connecting portions 18, 18a, 22, 22a, is provided.

The "wave" or delta shape of the partition shown in Fig. 13 is obtained, for example, by a heat treatment in a coating of the insulating strip 8. The mold may also be formed by rolling or by placing the film in a mold that dictates the appropriate shape or as known in the art. By such a three-dimensional indentation or bulge 38, the stability or structural rigidity of each partition wall 16e in the insulating body 10 can be further increased.

The insulating bar 60 shown in Fig. 14 according to a tenth embodiment is formed of two fixedly connected Isolierstegprofilen 8 (4-head insulating bar). The two Isolierstegpro file 8 are connected by an insulating body 10 similar to that of the sixth embodiment. That is, the insulating body 10 described in the fourth embodiment is provided on both sides with fixing portions 12a, 14a, and thus connected to an insulating rib profile 8 on both sides in the transverse direction X.

In a composite profile (not shown) which is formed with an insulating bar 6 according to this embodiment, the defined by the Verbundpro profile cavity 100 is already almost completely filled by the insulating bar 6. Since the insulating webs 6 are connected to each other perpendicular to the heat conduction direction, heat transfer by direct convection between the two profile parts 2, 4 is excluded.

Also shown in FIG. 15 insulating strip 6 according to an eleventh embodiment consists of two firmly interconnected Isolierstegprofilen 8 (4-head insulating bar). In contrast to the tenth embodiment, the insulating webs 8 are connected here by one or more of the insulator 10 described in the third embodiment (see FIG. 6). Again, in the cavity 100 of a composite profile (not shown), which is formed with such a Isoliersteg 6, no direct convection take place, since the insulating bars are connected to each other perpendicular to the heat conduction direction by the insulating body 10.

Fig. 16 shows an insulating bar 6 according to a twelfth embodiment. This insulating bar 6 also has two Isolierstegprofile 8. The insulating bodies 10 used in this embodiment are different from those of the eleventh embodiment in that the base walls 12, 14 of the insulating bodies 10 are not formed continuously between the insulating rib profiles 8 in the transverse direction X. That is, in a central region 40 no base walls are formed. In other words, two Isolierstegprofile 8 according to the third embodiment each have two in the transverse direction X opposite insulating body 10. The insulating bodies 10 located opposite one another are in each case interconnected by the zigzag-shaped partition 16 in a central area 40 (interruption area) connected. In the central area 40, no first or second base wall 12, 14 is formed.

The zigzag shape and the flexibility of the sheet material of the partition walls 16 in this embodiment enables the first distance a in the transverse direction X between the insulating ribs to be varied by stretching the zigzag profile in the central area 40. This allows tolerance compensation during assembly of the composite profile and simplifies assembly.

17 shows another exemplary embodiment of an insulating body 10. In this embodiment, a partition wall 16f is formed between the base walls 12, 14 in the form of a sine wave extending in the transverse direction X. The partition wall 16f also extends in this embodiment with a constant cross section perpendicular to the longitudinal direction Z and in the same.

In the following, further possible embodiments of an insulating web according to the invention are given by way of example.

The base walls may have any desired attachment areas. For example, the outwardly angled mounting portions may also be turned inward, i. be angled in the direction of the opposite base or intermediate wall. In this case, the attachment areas are preferably adhered.

In such an embodiment, the Isolierstegprofil has suitable lugs or projections into which the at least parts of the base or intermediate walls are inserted or clamped, or to which the base or intermediate walls are fixed by gluing or welding. In other words, the insulating bodies can be fastened to the insulating web profile in accordance with the known fastening of foam bodies to insulating web profiles.

Furthermore, one or more of the intermediate walls 34 can be connected to the Isolierstegprofil. The insulating web 6 shown in Fig. 6 may have any number of insulating bodies 10 which are fixed to the insulating web 8. The insulating body 10 may, depending on whether they are in the composite profile 1, as shown in Fig. 4, overlapping or, as shown in Fig. 1, installed opposite, ie, depending on their second width b2 and the width of the composite professional 1 at different heights in the height direction Y to the Isolierstegpro- fil 8 are attached.

In other words, the dividing walls may extend in a zigzag, meandering, wave-shaped or in any other way between respectively adjacent base or intermediate or foam walls and thus form any shaped cavities
