Description

The invention relates to an insulator profile between a pressing strip which is supported on the outer edge of a facade element and a supporting profile of a supporting profile construction, for example a façade or light roof construction.

The invention further relates to an existing support profiles, in particular posts and bars support profile construction, for example, for facades and the like. In this case, facade elements are held by a pressing bar on the support profile construction and between the support profile and the facade element, an inner seal is provided.

Input support structures described above, for example for facades are well known. As façade elements, for example, opaque facade filling elements or insulating glass panes are used. The facade elements are attached in the edge region of the support profile construction, for which a pressing bar or the like is provided. This connection area is important in terms of thermal insulation, since the good thermal insulation properties of the insulating glass ends in the edge region.

The European patent 1 020 578 describes an insulating element which is arranged in the gap space between two adjacent glass panes or filler panels of a facade. The insulating element disclosed herein is inserted in the receiving channel, which receives the fastening means of the pressing bar. A disadvantage of this configuration is that the inner seal is interrupted and forms a Ausspa tion in the region of the receiving channel, and therefore in the interior of the facade no continuous sealing level is available.

From the German utility model DE 299 18 219 U1 is a facade known for a low energy house. The facade described therein consists of a support structure with a plurality of carriers, the facade elements between them, such as panels, glass panes and so on record, with a pressure bar is provided which presses the facade part against the carrier and a thermal insulation in the pressure bar, where This facade is characterized in that the thermal insulation consists of at least two Dämmkörpern.

From the publication GB 2 137 673 Another facade construction is known, which seals the facade elements by means of a seal, which is guided over a fastening web to the outside. In this case, the fastening web has a head which has to be arranged between sealing parts. The design is quite complicated and involves the risk of slippage of the seal when mounting the facade elements. Furthermore, the shape or the design of the sealing arrangement is chosen so that it can be used only on the special facade structure, namely the profile shown there. Thus, there is the problem that different sealing elements must be maintained for each different facade design.

From the publication EP 1 643 049 A2 (According to the art according to Article 54 (3) EPC) a supporting profile construction of the applicant is known. In this case, a seal arrangement is described, which is characterized in that a plurality of sealing elements are provided. The support profile construction of the embodiment shown here can be used in particular in so-called two-part facade profiles.

From the publication EP 0 971 081 A2 is a building facade or roof facade with a framework of posts and bars known. From this document it is known to put a fastening profile as an insulator profile over a screw. The insolator profile then engages behind the inner seal. Even with such an embodiment, the risk of slipping of the seal is present, so that the inside between the support profile construction and the facade elements is not as tight as necessary. This leads to heat loss and possibly also to corresponding condensation. To eliminate such shortcomings, the facade elements must be solved again, and then align the seal accordingly. This also leads to increased expenses.

It is an object of the present invention to realize an arrangement which leads both to a well-insulated as possible support profile construction and on the other on the inside, in particular between the support profile construction and the

Facade elements is as tight as possible.

This object is achieved by the features described in claims 1 and 12.

To solve this problem, it is assumed that an insulator profile as described above, wherein the insulator has a U-shaped or H-shaped lower portion and an inner seal provided on the support profile at least partially overlaps and a positive or cohesive connection for holding the insulator profile on the inner seal is provided.

By the proposal according to the invention it is achieved that on the inside of the facade element, which the support profiles facing, a continuous sealing level exists. This sealing plane is formed either by a continuous inner seal or the insulator profile is part of the inner seal. For this purpose, it is provided that the insulator profile at least partially overlaps or covers the inner seal, the term "overlap" is to be understood here so that the insulator profile between the inner seal and the pressing bar is arranged, so the insulator profile in the installed state, the inner seal at least partially covers. However, the term "overlapping" is also very broadly to be understood, especially in the manner in which it is formed in the drawing, in which the insulator profile and the inner seal, especially in the hut- or U-shaped structure, at least laterally partially covered.

The proposed positive or cohesive connection between the insulator profile and the inner seal two synonymous synergistic supporting effects are achieved. The positive or cohesive bond between insulator profile and inner seal improves the sealing effect in any case, especially when the insulator profile has to take over sealing tasks, for example, if the inner seal consists of several elements. Furthermore, however, the positive-fit or cohesive bond also leads to a significant improvement in the mechanical stability. The simple frictional attachment of the insulator profile is uncertain, since the clamping forces are insufficient to ensure that the insulator profile remains in position. The dimensional tolerances in the seals are too large to be able to use a reliably functioning, only frictional composite between inner seal and Insolatorprofil with reasonable certainty. However, an exact alignment of the insulator profile is necessary for a proper sealing or thermal insulation effect, by a correspondingly firm connection, the is achieved by the inventively proposed positive or cohesive connection is ensured.

In a preferred variant of the invention, it is proposed that the positive connection is produced directly or indirectly between insulator profile and the inner seal. Under a direct positive connection is understood an arrangement in which the insulator profile and the inner seal itself, without additional aids, learn a direct positive locking. Such a configuration is, for example, a clip connection arranged between the insulating profile and the inner seal. In an indirectly realized positive engagement of the positive engagement by means of an additional element, for example, a screw, clamp or the like is achieved, which positively with at least one and / or other part.

Various examples of a direct or indirect form closure are given below.

For example, it is provided that a direct positive connection is realized by a arranged between the insulator profile and the inner seal clip connection. A clip connection is realized in such a way that an often spring-bearing element, for example a nose, engages in a corresponding recess, snaps, engages or clipping. The advantage of such a compound is that it is on the one hand solid and stable and on the other hand, if necessary, can be solved without destruction again. In the embodiment, for example, also realized in the drawing, the insulator profile carries a protruding nose without thickening, which engages in a corresponding recess of the inner seal. Since the nose is arranged on the strip-like leg of the insulator profile, the nose is also somewhat resilient or held under prestress. It is therefore able to lock into the recess. Of course, one also belongs

reverse arrangement to the invention, in which, for example, the inner seal has a corresponding thickening or nose, which engages in a corresponding recess on the insulator profile. In this case, the necessary for the latching elasticity of the two aforementioned variants can be derived either from the elasticity of the inner seal or from the elasticity of the Isolatorprofiles. Of course, these two can also interact with their elasticity in the context of the invention.

In another variant of the invention, the insulator profile is provided on its side facing the inner seal with a toothing and thus achieves a direct positive connection with the inner seal. For example, the insulator profile is formed as a reversed U, which engages over the inner seal, for example in the region of the receiving channel. The insides of this U of the insulator profile now have a toothing, preferably a barb-like toothing and claw or bite into the elastic sealing material of the inner seal. The multiple row of teeth causes an additional sealing effect, especially if in the U, the gap of the two abutting seal parts of the inner seal is located.

Furthermore, the solution according to the invention also comprises at least one screw, clamping bolt, nail and / or clamp, which is provided by which the insulator profile is held on the inner seal, wherein the screw, clamping bolt, nail and / or clamp either a connection between the insulator profile and the inner seal produces or the screws, clamping bolt, nail and / or clamp the insulator profile attached to the support section or to elements of the support profile or between the insulator profile and inner seal a Velcro is provided. The aforementioned variants are part of the advance, which is realized indirectly as with other aids. The The invention leaves it open whether the screw, clamping bolt, nail and / or clamp between the insulator and the inner seal are used for a positive connection or with the aforementioned fasteners, for example, a connection of the insulator profile on the inner seal in the support section or for example Receiving channel takes place as part of the supporting profile. The term "positive engagement" is also understood that a sufficient bonding force between the insulator and the inner seal, for example, is impressed by a separate fastener, which leads to a secure hold of the insulator on the inner seal on the one hand and on the other hand to an additional sealing effect , If necessary, this force is so great that a form-fitting bond, that is to say an alignment of the contours of the insulator profile and the inner seal, which interacts accordingly, takes place.

In the sense of the abovementioned definition and within the meaning of the invention, the use of a Velcro connection, that is to say a Velcro strip, which cooperates with a corresponding adhesive tape, is also understood to be indirect form-fitting. The two interacting sides of the insulator profile or the inner seal each have a part of the Velcro strip, which together form the Velcro connection. Due to the Velcro, which is formed by a plurality of barb-like elements that engage in loop elements, here the positive engagement is given. The advantage is that even this composite is non-destructive solvable, for example, during assembly can be implemented.

In a further variant of the invention, it is provided that a material connection between the insulator profile and inner seal by an integral formation of the insulator profile with the inner seal, in particular by a coextrusion or is formed by an adhesive bond. In a cohesive connection, the insulator profile and the inner seal are actually only separated by destruction of one or the other element again. Such an arrangement is of course mechanically stable and easy to position and also tight. Such an arrangement can be achieved, for example, by a coextrusion process in which the inner seal consisting of a relatively softer plastic material is extruded as a profile in a common extrusion process with the insulator profile made of a harder plastic, each of the same type. The processes for coextrusion are well known. In another variant, the insulator profile and the inner seal are each made separately and then joined together, for example by an adhesive bond. For the purposes of the invention, a punctual adhesive connection already suffices. Of course, a variant is included, in which a full-surface longitudinal adhesive bond (parallel to the longitudinal extent of the supporting profile) is used.

By the proposal according to the invention, the gap between the insulating glass panes or between the support section and the pressing bar is reduced and / or subdivided and already thereby deteriorates the heat transfer by convection, which also leads to an improvement of the thermal insulation. The above-described intermediate space is also often described as a rebate space which is arranged between the glass panes or insulating glass panes. Conveniently, care is taken to ensure that the material of the insulator profile has relatively poor thermal conductivity, so as to further improve the thermal insulation. The insulator profile has heat-insulating, ie insulating effects.

The insulator profile also improves the leadership of the fastener for fastening the pressing bar. The insulator profile extends in the direction of the pressing bar parallel to this and is, for example, U- or H-like or similar, whereby a screw inserted into a bore of the pressing strip then already experiences a guide in the longitudinal direction of the profile.

Furthermore, the arrangement according to the invention achieves that, for example when horizontally installed in a latch, a seam separation takes place, which is favorable with regard to the formation or discharge of condensed water. For example, it is provided in this application example that the insulator profile carries a rebate seal, which seals the gap between the pressing bar and the insulator profile.

A significant further advantage of the invention is that the insulator profile is fixed to or on the inner seal. This embodiment of the invention causes a captive in production or on the site. As a captive while the fact is considered that the insulator is reliably arranged on the inner seal, so the assembly of the inner seal with the insulator profile and this can not be accidentally forgotten.

Furthermore, the inventive design leads to the fact that when unscrewing the mounting screws for the pressing bars no lifting of the insulator profile. This creates no gap between the insulator profile and the seal.

Furthermore, this improves the sealing (no capillary effect) when the outside water seeps or condensed water is formed.

The invention is both in one-piece inner seals as well as in multi-part inner seals, for example, two-part or multi-part seals usable.

In a further variant of the invention it is provided that the insulator profile carries an insulating part. The insulating part has the additional task of improving the thermal insulation in the rebate area. For reasons of stability, the insulator profile is often made of a relatively hard material, for example a plastic material. The combination with an insulation part optimized with regard to the heat-insulating property largely reduces the air space or intermediate space or rebate space, whereby the air circulation in this area is prevented or greatly reduced and thus leads to a corresponding improvement of the thermal insulation.

It is proposed according to the invention that the insulating part is formed for example as a sealing lug or as an insulating element. Both variants are part of the invention, that is, the insulating part can be formed both as a sealing lug, so as a strip-like, relatively flexible element, or be formed as, for example, made of foamed material existing insulating element. Through the use of one or more sealing flags as Dämmteil also the space between the insulator profile and the end faces of the facade elements and / or divided between the insulator profile and the pressing bar and the formation of air circulation, which causes a heat transfer, prevents or reduces. Also, the attachment of lateral sealing lugs, for example as a one-piece design on the insulator profile, preferably made of soft material (softer than the hard plastic of the insulator profile), reaches the subdivision of the air space and thus leads to a suppression of air circulation. The soft plastic has on the one hand a certain flexibility and on the other hand a low heat conductivity. The insulating part consists for example of soft plastic or good insulating foam.

In a variant according to the invention it is provided that the insulating part is formed as an insulating element. The insulating element extends in particular between the insulator profile and the pressing bar and fills this area of the intermediate space. The insulating element consists of a material that has a high thermal insulation property, such as polyurethane or polystyrene.

In a preferred variant of the invention it is provided that the support profile is designed as a wood, aluminum or steel profile. The invention can be used in any embodiment of a facade, for example in wood, aluminum or steel facades, the invention is not limited to a special material.

In a preferred variant of the invention it is provided that the support profile has or carries a receiving channel for receiving fastener strip holding fasteners. Usually, the pressing bar is fastened by a plurality of fastening means, for example fastening screws on the support profile. Conveniently, this is a receiving channel provided, said receiving channel is integrally disposed on the support profile, so for example in an aluminum facade in the aluminum support profile, which has been produced in an extrusion process, has been incorporated with. Alternatively, it is possible that the support profile carries a separate second part, namely a receiving channel, which then for example also consists of a different material than the support profile. It is thus possible, for example, to attach a receiving channel made of aluminum to a supporting profile made of wood. Of course, it is also possible that the fastening means engage directly in the support profile, for example, cut corresponding screws in a support profile also formed wood and so hold the press bar.

In a preferred variant of the invention it is provided that the receiving channel is U-shaped. Seen in section, the receiving channel is U-shaped, wherein the opening of the U is oriented in the direction of the pressing bar. Optionally, the inner wall of the U, so the inside of the legs, a corresponding ribbing, which cooperates with the threads of the mounting screw. In addition, however, it is possible that the receiving channel may have any other shape, wherein the receiving channel is formed like a profile, so it should also be referred to as a receiving channel profile in the context of the invention. For example, it is also possible to provide a box-like receiving channel profile in which the fastening screws and other fastening means, for example rivets and so on, intervene.

Conveniently, the receiving channel extends in particular into the intermediate space which exists between the adjacently arranged facade elements. Especially this gap is a weak point in the thermal insulation. The receiving channel is covered by the inner seal and sealed and ultimately carries the insulator profile. Therefore, the receiving channel takes on a variety of tasks, he not only forms the abutment for the mounting screws, but also serves as a "foundation" or mounting base for the insulator profile, which is for example placed clamped on the inner seal and on the outer sides of the U-shaped supported the box-shaped receiving channel profile. Of course, other possibilities according to the invention are also provided, for example separate fastening strips on the inner seal or fastening strips on the support profile, on which the insulator profile is supported, or held and guided.

In a preferred variant of the invention, the insulator profile engages over the inner seal. The insulator profile is fixed in the outer wall of the inner seal. This is done for Example in that a recess is provided on the inner seal and on the inner wall of the insulator profile, whereby a clip mechanism is formed by the resilient movement in particular of the protruding mounting leg of the insulator profile, on which the elevation is arranged.

However, this principle can also be reversed, such that an increase is provided on the inner seal, which engages in a corresponding recess or depression on the plastic profile. Even so, a clip effect is achievable.

Moreover, it is possible to provide, for example, a special bond between the inner seal and the insulator profile.

In a preferred variant of the invention it is provided that the insulator profile has no hollow chambers, that is formed without a chamber. The design of the insulator profile is chosen so that it has such a small cross-section that it sets no air circulation and so no heat transport occurs. But it is also possible that the insulator profile is closed by other elements that do not belong to the insulator profile, and thus forms a closed volume. Alternatively, it is provided that the insulator profile has one or more longitudinal chambers or hollow chambers, but whose cross-section is dimensioned so that a heat transfer by convection does not take place.

Furthermore, the invention proposes that the insulator profile is held on the region of the inner seal which surrounds the attachment channel. By such an embodiment ultimately serves the essay channel at the same time as a base or bearing for the insulator profile and results in an increased stability. In a variant according to the invention it is provided that the inner seal consists of two or more parts. As a result, there is a gap between the two parts. Cleverly, the insulator profile is now arranged so that it covers the gap. As described above, an additional sealing effect is sought by the material or positive connection, which is particularly favorable in a multi-part inner seal. The gap is then below the insulator profile, the insulator profile assumes the task of the sealing level in this area.

Advantageously, it is provided that the inner seal is formed like a hat. This hat-like structure results, for example, in a vertical section to the longitudinal extent of the inner seal. The central region of the inner seal engages over the attachment channel, the seitichen ends or lateral areas form a Fassadenelementabdichtung which is arranged between the facade element and the support profile (in particular on the inside of the facade element). This embodiment is possible both in a one-piece as well as a multi-part inner seal. Cleverly, however, it is sufficient to provide a two-part inner seal, as shown in FIG. The invention is, however, not limited thereto.

In the context of this invention, both independent protection for an insulator profile as well as for a support profile construction are claimed with such an insulator profile. As far as features are described only in connection with the insulator profile, these of course also apply to the arrangement with the support profile construction as co-disclosed and vice versa. This means that features that are mentioned only in connection with the support profile construction, of course, in the same way also refer to the insulator profile. The arrangement of the features is in accordance with the invention interchangeable and as also disclosed according to the invention.

Further advantageous embodiments of the invention are described in the subclaims.

It is understood that the features mentioned above and those yet to be explained not only in the combination specified, but also in other combinations according to the invention can be used.

The invention is illustrated schematically in the drawing.

a detail after Fig. 1a or 6a and

Fig. 2

a vertical section through a support profile according to the invention.

The invention is particularly in Fig. 1a shown schematically. With 1, the support profile is marked. This is designed for example as an aluminum profile, it is designed in one piece with the receiving channel 7, as it is, for example, in an extrusion or extrusion in aluminum feasible. Instead of the aluminum profile shown here but other materials can be used, for example, a steel or wooden support profile. 1

The support profile 1 is located in the support profile construction usually on the inside facing side. The

Support profile 1 carries facade elements 6, which are formed here, for example, as insulating glass panes. The insulating glass panels are usually made of two glass panes, which are spaced by a spacer. Between the facade element 6 and the support section 1, the inner seal 4 is provided.

The facade elements 6 are held by the pressing bar 2 on the support section 1. For this purpose, fastening means 8 are provided, which presses the pressing bar 2 against the facade elements 6 and thus holds on the support section 1. The fastening means 8 is provided, for example, as a fastening screw, it engages in a receiving channel 7 of the support section 1. The receiving channel 7 may be formed integrally with the support section or be realized as a separate element, for example, as a tower-like receiving channel 7 (for Example with a wooden construction). The receiving channel is U-shaped in section.

Between the pressing bar 2 and the facade element or the insulating glass pane 6 is the outer seal 15. On the outside is located on the pressing bar 2, a cover strip. 2

The sides or end faces 16, 16 'of the facade elements bound together with the inner seal 4 and the pressing bar 2 the space (or rebate space) 17th

In the intermediate space 17 projects, sitting on the inner seal 4 or fixed by this, the insulator profile. 5

The inner seal 4 is integrally formed in the embodiment shown here and hat-shaped. In this case, the middle, raised region 18 covers the receiving channel 7, which likewise projects into the intermediate space 17. The construction of the inner seal is substantially symmetrical, in the edge area the sealing area 19 is provided, which in particular seals the intermediate area between the supporting profile 1 and the facade element 6.

The middle area and the sealing area 19 are connected by L-type connecting areas 20. The entire inner seal 4 is formed profiled and strip-like and naturally extends along the edge of the facade element. 6

The hat-like configuration of the inner seal 4 serves to cover the receiving channel 7.

In the embodiment shown here, the receiving channel 7 is U-shaped in section, but it can also be realized differently. By standing in the receiving channel 7 in the intermediate space 17 of this interspace or rebate 17 is already reduced accordingly and thereby reduces the area to be insulated accordingly.

Since, in this embodiment, the receiving channel 7, concealed with the inner seal 4, like a strip into the gap 17, this protruding strip lends itself to fix the insulator profile 5 on this strip-like, central region 18.

The insulator profile 5 is seen in section, at least in the lower region U-shaped, such that this U aufstülpbar or attachable to the central region 18 of the hat seal. On the whole, this is U-shaped or H-shaped or similar, wherein the specific embodiment of a U- or H-shape is derived, or sub-areas U- or H-like.

The fixation of the insulator profile 5 on the inner seal 4 is designed such that the downwardly projecting

Mounting leg 12, 12 'between them receive the hat-shaped central region 18 of the inner seal 4. Since this central region 18 in turn bears against the receiving channel 7, the insulator profile 5 ultimately protects itself indirectly from the receiving channel 7. The central region 18 can not escape, this is applied to (a U-shaped) receiving channel 7 at. The projecting attachment legs 12, 12 'spring slightly opposite to the rest of the insulator profile. 5

At the mounting leg 12, 12 ', a thickening 13 is provided (see FIG. 1c) , This thickening 13 is provided on the inner seal 4 facing side like a nose. The inner seal 4 carries on its side facing the insulator 5 side, in the central region 18 a recess 14 which cooperates with the thickening 13, for example in the manner of a clip connection. The resilient configuration of the attachment leg 12, 12 'facilitates this einklippsen.

The recess 14 is located at the end of the connecting region 20 or at the beginning of the central region 18 in the region of the inner seal 4, which is oriented substantially parallel to the longitudinal extension of the mounted fastener 8 in the installed position.

The arrangement is chosen so that when mounting the insulator profile 5 on the inner seal 4, the insulator 5 is pushed onto the web-like central region 18 until the thickening 13 engages in the recess 14 and holds einkrallend. The advantage of this embodiment is, in particular, that the groove-like recess 14 in the manufacture of the inner seal 4 can be incorporated in a simple manner. The thickening 13, which protrudes as a strip-like heel or nose, can also be provided in the insulator profile produced in an extrusion process. However, this results in a mechanically strong Connection that ensures that the insulator profile is not lost, for example during assembly or transport. In addition to this Einklippsverbindung, which is of course also feasible in the sense of a kinematic reversal, of course, other form-locking connection types are possible, such as screws or rivets. Also, for example, the projecting nose may be provided with a barb or a sharp edge to achieve clawing. In the sense of kinematic reversal is provided that the inner seal 4 has a corresponding thickening, which is able to engage a corresponding recess of the insulator profile 5.

Furthermore, as described, the insulator profile 5 is H-shaped or similar, wherein the upper region of the insulator profile is narrower than the lower region of the seating area that overlaps the central region 18 of the inner gasket 4.

The insulator profile 5 is constructed substantially symmetrically, wherein the guidance of the fastening screw 8 is facilitated by an angular configuration of the intermediate struts 21. The intermediate struts 21 connect the two side parts 22, 22 ', which form the fastening legs 12, 12' in the lower region. The angular configuration of the intermediate struts 21 is chosen so that the angle goes in the direction of the receiving channel 7. The angle is preferably in the middle.

Depending on the thickness of the facade element 6 or the insulating glass pane 6, the height of the insulator profile 5 can be selected. In the left embodiment according to FIG. 1 a shown example, a relatively thin insulating glass pane 6 is provided, in the right ( FIG. 1 b) shown embodiment, this is thicker. The insulator profile 5 is correspondingly adjustable in height. Optionally, it then has a plurality of intermediate struts 21, the lowest Intermediate strut 21 is located at a plurality of points or edges or over the entire area on the central region 18 of the inner seal 4.

The intermediate strut 21 is penetrated in sections by the fastening means 8, usually the fastening means 8, for example the fastening screws 8, are inserted at a distance of 20 to 30 cm.

As far as a plurality of intermediate struts 21 is used, formed between these, laterally bounded by the side parts 22, 22 'hollow chambers 23, wherein the cross section of these hollow chambers is dimensioned so that an air circulation does not set. In this case, a cross-sectional area of approximately 1 to 2 cm ^{2 has} proved favorable.

At the upper end (the pressure bar 2 facing) is located on the side panels 22, 22 'each inwardly projecting edge or edge 24, 24'.

The advantage of these edges or edges 24, 24 'is in particular in the embodiment according to FIG. 2 clear. The insulator profile 5 is U-shaped in the direction of the pressure bar 2 and forms a receptacle 10. In this receptacle 10 is a rebate seal 25 can be used, wherein the rebate seal 25 has a sidecut which cooperates with the inwardly projecting edges 24, 24 'in such a way in that the seam seal 25 is fixed and held. The seam seal 25 seals the insulator profile 5 from the pressure bar 2 down. The seam seal 25 is symmetrical and has two sealing strips 26, 26 '.

Since the construction of the arrangements according to the invention shown is essentially always identical, a repetition of the description of all features in the individual figures is omitted and only described what, in the figure shown was changed. Of course, the variants shown can be combined with each other accordingly, which is clear to the skilled person. The invention is therefore limited to the specific embodiment of the embodiments shown in any way.

In order to achieve a secure connection between the inner seal 4 and the support profile 1, for example, as in FIG. 3 shown on the support profile 1 side, at a relatively large distance from each other, retaining strips 40, 40 'is provided. These retaining strips 40, 40 'engage in corresponding recesses 41, 41' of the inner seal 4, which are provided in the sealing region 19 on the support profile 1 side facing.

The arrangement of the retaining strips 40, 40 'can be provided both on the support section 1 as well as on a receiving channel 7 forming profile, which is carried out independently of the support section 1, so as a separate component.

An essential advantage of the invention is furthermore that the insulator profile 5 carries an insulating part 30. According to the invention, several variants are possible for the embodiment of the insulating part 30. So shows FIG. 3 for example the use of sealing lugs 31, 31 '. The sealing lugs 31, 31 'divide the gap 17 on. The result is a partial gap 33, 33 ', wherein the configuration of this partial gap 33, 33' is dimensioned so that as possible no heat transfer (for example, by convection) sets.

In the embodiment shown here, the sealing lug 31, 31 'in the central region of the mounting leg 12, 12', ie provided at the level of the upper edge of the receiving channel 7. Of course, it is possible to further divide the gap 17 by a plurality of sealing lugs arranged on the side part 22, 22 '.

Another advantage of the invention lies in the fact that between the sealing lug 31, 31 'and the side or end face 16, 16' of the facade elements 6, 6 ', a small gap 35 remains. The arrangement is such that this gap results, whereby a bending stress of the sealing lance 31, 31 'in particular in the connection region 34, where the sealing lug 31, 31' to the side part 22, 22 'and the mounting leg 12, 12' connects, is avoided , Such mechanical stress could otherwise lead to tearing or breaking off of the sealing lug. The gap that results is small so that little or no air circulation results. If the intermediate space 17 is subdivided by a plurality of sealing lugs 31 (not shown here), the result is a type of labyrinth seal with an even lower tendency to convection and higher, that is, better insulating effect.

In the in FIG. 3 the embodiment shown, the insulating part 30 is formed integrally with the insulator profile 5. The insulating part 30, here designed as a sealing lug 31, is for example made of a soft plastic to give a certain flexibility, whereas the cooperating with the inner seal 4 insulator profile 5 made of harder plastic, for example, hard plastic, to a certain mechanical stability For example, to have for screwing the mounting screws 8. The rigidity of the insulator profile 5 also results in a secure connection or fixation of the insulator profile 5 on the inner seal 4.

But it is also possible in the context of the invention, the insulating part 30 as a separate from the insulator profile 5 component, for example as a slip-on form. Such a Aufsteckprofil is attached, for example, to the insulator profile 5 and subdivided in a suitable manner also the gap 17. In such a variant, it is also possible that the insulating part itself is formed in several parts, ie from a Plural of each attachable sealing flags, for example.

In the in FIG. 3 Furthermore, the insulator profile 5 is H-shaped or similar in section and has only one intermediate web 21. According to the invention, therefore, an insulator profile 5 is provided that is equipped with one or more intermediate webs 21. The gap 17 is thereby reduced by further, strip-like elements that can be used with the insulator profile 5, for example, at the receptacle 10. However, such additional parts (not shown) do not count toward the insulator profile 5.

In addition to the in FIG. 3 shown H-type configuration of the insulator profile 5 shows FIG. 4 This U-shaped configuration is oriented with its opening just the other way around, as the U-shaped configuration of the receiving channel 7. The U-shaped configuration of the receiving channel 7 is used for Preßleiste 2 and a preferred variant of Invention.

Due to the U-shaped configuration of the insulator profile 5, this does not extend so far into the gap 17. The insulator profile 5 carries in this embodiment, another variant of the insulating part 30. In the embodiment shown here, the insulating part 30 is formed as an insulating element 32, which seen in cross-section large areas of the intermediate space 17 fills. The strip-like insulating element 32 has lateral ribs 36 which, forming a gap or forming no gap, lie directly against the sides or end faces 16, 16 'of the facade elements 6. The insulating element 32 shown here is also applied to the pressing bar 2 and is optionally pressed by this against the insulator profile 5, or the insulator profile is fixed by the insulating element 32 on the hat-shaped central region 18 of Inner seal 4 postponed. Air gaps are thereby avoided, a circulation suppressed.

The insulating element 32 is preferably made of a foamed material, for example polystyrene or polyurethane and the like, as is customary for example for thermal insulation elements in use.

In the embodiment shown here, the insulator profile 5 and the insulating element 32 are each designed as a separate component and connected to each other, for example, by a bond 37 in the contact surfaces. But it is also possible, even the insulating element 32, as well as the sealing lug 31 shown here, integrally formed with the insulator profile 5 and so that insulating member 30 to realize.

The intermediate space 17 is subdivided by the ribs 36 and the sealing lug 31 into a multiplicity of individual partial intermediate spaces 33, the cross-sectional area of which, if possible, is so small that no air circulation is established. The rib-like design of the insulating element 32 provides a certain tolerance compensation in the insulating element 32, protruding material of the ribs 36 is then pushed away laterally, the resulting partial spaces thereby somewhat reduced, but does not hinder the assembly. Of course, it is also possible to realize relatively complex, for example, single-material, one-piece, an insulating member 30 forming insulator profiles 5, wherein the insulating member 30 as an insulating element 32 as in FIG. 4 is shown formed.

Of course, a combination of the two different variants of the insulating part 30, namely the sealing lug 31 and the insulating element 32 to the invention, as this in FIG. 4 is shown.

The invention can also be realized with a support profile 1 designed as a stretch post 45. In the expansion post 45, the support profile 1 consists of two profile parts 50, 51 which are movable relative to each other so that they can stretch slightly. This is realized in that, for example, a profile part 52 of the first post half 50 engages in a groove-like recess 53 of the second post half 51. Of course, this arrangement can be provided several times on the expansion post 45. The two post halves 50, 51 each also have a retaining strip 40, 40 'for the inner seal 4. In the embodiment shown here, the inner seal 4 is also divided, that is, the inner seal 4 consists of several elements, in the example shown here of two halves. Between the left, first half 47 of the inner seal 4 and the right, second halves 48 of the inner seal 4 is a gap 46. The gap 46 is located in the center plane, in the region of the axis of symmetry. Er.befindet below the web 21 of the insulator profile 5. The arrangement is chosen so that the clip connection or fixation of the insulator profile 5 on the inner seal 4 is so strong and reliable that no moisture can penetrate through the seal. This is achieved by correspondingly narrow tolerances in the design of the insulator profile 5.

Moreover, the insulator profile 5 is formed as in FIG. 1a described. By this proposal, it is possible to use the invention in the field of expansion posts.

Fig. 6a shows a further variant of the invention. With the fastening means 8, for example a screw, it is shown that the pressing bar 2 is held in the receiving channel 7 and thus holds the facade elements 6. Furthermore, the shows Fig. 6a but also the use of an indirect positive connection by the fastening screw 80. The fastening screw 80 is screwed into the insulator profile 5. The insulator profile shown here 5 "rides on the inner seal 4. The hat-shaped inner seal 4 spans the receiving channel 7 and on this saddle-like configuration of the inner seal 4, the Befestigungsschenkenl 12, 12 'of the insulator 5. In the upper area, the insulator profile 5 with respect to the legs 12, 12th 'in the direction of the pressing bar 2 slightly recessed side parts 22, 22' These side parts 22, 22 'are connected by two intermediate struts 21, which are here V-shaped.

At the upper end of the side parts 22, 22 'is followed by a dovetail guide 53 formed by the above c-type endings, in which the insulating element 32 is inserted by clamping with a corresponding training, such that the foot 38 of the insulating element in the dovetail guide 53rd is held. The insulating element 32 fills the gap up to the pressing bar 2 and divides this gap.

In the bottom of the dovetail guide 53, which is formed by the upper web 21, a screw head of the screw 80 is arranged. By this screw 80, the insulator profile 5 is screwed through the inner seal 4 into the receiving channel 7, a parallel to the support profile extending screw. There, the same fastening technique is used as for the pressing bar 2 by the fastening screw 8. By screwing the screw 80, a corresponding holding force between the insulator profile 5 and the inner seal 4 is generated. This solid composite, which results in particular by the cutting of the threads in the walls of the receiving channel 7 (positive engagement), is a possible variant of the indirectly formed positive connection according to the invention.

In the embodiment shown here, a clip connection is additionally arranged. These two measures (clip connection and screw with screw 80) can optionally also be used simultaneously, but often only one or the other variant is provided.

Although the screw 80, the inner seal 4 injured, the sealing properties are not reduced, since this injury is below the Isolatorprofiles, ie between insulator and inner seal and the elasticity of the inner seal 4 causes it closely conforms to the screwed screw 80. In addition, the sealing plane is still protected, since in addition the side parts 22, 22 'participate as a sealing plane in this case. Penetrating water is reliably retained and can not reach the inside, behind the inner seal 4 on the side of the supporting profile 1.

This in Fig. 6b shown detail corresponds to the arrangement according to Fig. 1c , The double design with direct and indirect positive locking can be favorable, for example, for mounting purposes.

Of course, the V-shaped configuration of the intermediate strut 21 leads to a corresponding guidance of the fastening screw 8 or 80 to be screwed, since it wishes to penetrate this at the lowest point of the V-shaped intermediate strut 21 and thus experiences a corresponding guidance. Also, the underlying intermediate strut 21, which rests directly on the inner seal 4 is also V-shaped and aligns in the same way the einzudrehende screw 8, 80 from. This allows the screw 8, 80 safely and reliably in the screw of the receiving channel 7. The same is of course possible with appropriate nails or bolts.

It can also be provided in principle that between the central region 18 and the web 21, a certain spacing is provided, which further subdivides the gap 17 and thus improves the thermal insulation accordingly. A holding one Connection between the inner seal 4 and the insulator profile 5 is then carried out, for example, by a clip connection, a Velcro or adhesive.
