Description

Insulating web

The present invention relates to an insulating web for connecting two profile parts of a door, window, or facade element.

The inner profile and the outer profile of a thermally separated composite profile, such as an aluminum composite profile, for window, door or facade elements are connected by one or more insulating bars. The inner and outer profiles often have different temperatures. In addition to heat conduction through the Isolierstege heat is also passed through convection and 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 be painted for visual reasons.

From EP 1 531 228 A1, a composite profile is known, in which an outer profile and an inner profile are connected by two insulating webs. A present between the profiles and the insulating web cavity is filled by heat-insulating moldings, which are each attached directly to the insulating bars.

From DE 196 22 278 Al a Verbundpro profile is known in which a Außenprofü and an inner profile are connected by two insulating bars. On the insulating bars insulating body are arranged, which partially fill the cavity between the profile parts and the insulating webs.

EP 1 347 141 A1 discloses a method for producing a heat-insulating and connecting web and an insulating and connecting web produced by this method. In the method, first a plastic profile with a trough-shaped area is produced. Subsequently, an insulating foam is introduced in the liquid state in the trough-shaped area. The foam with simultaneous connection with the plastic profile foamed to a above the trough-shaped area beyond the insulating strip.

From DE 100 63 894 Al an insulating strip is known, is attached to the insulating strip in the self-foaming plastic. The Dämmleiste may be integrally formed with a one or two hollow chambers forming web arrangement on which the self-foaming plastic is applied.

From DE 195 04 601 Al a composite profile is known in which webs are formed on the composite profile for holding self-foaming plastic. These webs are spread apart during foaming of the self-foaming plastic.

From DE 296 21 419 Ul a composite profile is known, in which the Dämmstege have at least one pointing into the interior of Dämmzonenhohlkammer hollow profile body.

From EP 1 215 360 A a composite pro fϊl is known in which an outer profile and an inner profile are connected by two insulating webs. The insulating bars are connected by a diagonal strut.

From EP 1 154 115 Al a composite profile is known, in which the cavity between the profile parts and the insulating bars is filled with foam.

It is an object of the present invention, an insulating web for a composite profile for door, window, or facade elements for connecting two profile parts of the composite profile, which improves the provision of thermal insulation, and to provide 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 10.

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

It is given an insulating web for a composite profile with an attached insulating body of connecting web assembly, insulating body profile and foam body, which allows different and / or increased insulator heights at the same foam height.

The foam body can be arranged at a relatively arbitrary distance from the Isolierstegprofil with any orientation. The insulating body can be formed with different shapes that allow easy adaptation to the profile parts used.

It is a modular insulating bridge system allows for the same Isolierstegprofilen and foam bodies allows different insulator heights.

The thermal conductivity of the foam body and that of the Isolierkörperprofils with connecting web may have the same value or very similar values, so that the thermal conductivity of the entire insulating body is substantially homogeneous.

Another advantage is that the Isolierstegprofil can be formed with lower wall thicknesses than conventional profiles for a same load to be absorbed, since a part of the load can be absorbed by the preferably structurally stiff connecting webs.

A thinner insulating web profile further reduces the heat conduction compared to a conventional insulating web profile.

The insulating bar is paintable. He also remains dimensionally stable during the painting process.

The insulating web profile can be assembled and / or calibrated separately from the insulating body. As a result, a Isolierstegprofϊl be created with low manufacturing tolerances.

Advantageously, the insulating web profile and the Isolierkörperprofü are first made of a suitable material as profile parts with a constant cross-section, for example by extrusion. The foam body is attached to the matched insulator profile, i.e., e.g. foamed into the foam body tray. These parts can then be combined as needed. The connecting webs connect the Isolierkörperprofile and Isolierstegpro file e.g. by means of clip connection.

1 b shows a composite profile (for example window frame) with a first profile part 1 in the form of a window frame profile outer part and a second profile part 2 in the form of a window frame profile inner part. The first profile part 1 and the second profile part 2 each extend in a longitudinal direction z. The two profile parts 1, 2 lie in a transverse direction x, which is perpendicular to the longitudinal direction z, opposite. The profile parts 1, 2 have a wall thickness dl.

The first profile part 1 has a second profile part 2 facing the inside. On the inner side, two receivers 13, 14 are formed for curling insulating bars, which are arranged at a distance in a vertical direction y, which is perpendicular to the longitudinal direction z and the transverse direction x, and extend in the longitudinal direction z. The recordings 13, 14 are reflected by a roller hammer 11 and a curl he 12 limited.

The second profile part 2 has an inner side facing the first profile part 1. On the inside, as in the first profile part 1, two receptacles 13, 14 are formed, which extend in the longitudinal direction z. The receptacles 13, 14 are limited as in the first profile part 1 each by a rolling hammer 21 and a retraction abutment 22.

A first insulating web profile 3 and a second insulating web profile 4 are arranged between the profile parts 1, 2 in the transverse direction x. The Isolierstegpro file 3, 4 extend in longitudinal direction z. They have a longitudinal cross-sectional z shape constant. The Isolierstegprofile 3, 4 have at the two edges in the transverse direction x each curl projections in the form of Einrollleisten 31, 41 on. The Einrollleisten 31, 41 have a dovetail shape in cross-section perpendicular to the longitudinal direction z. The Einrollleisten 31, 41 are each connected via an angled (bent) gate 34 with a central portion 35 of the insulating web, which extends in a cross-section in the xy plane straight between the angled portions 34. The relevant for the heat conduction central portion 35 has a thickness (thickness) d2 in the height direction y. The insulating web profile 3 has a width bl in the transverse direction x. The central portion 35 has a width b35 in the transverse direction x.

The receptacles 13, 14 of the profile parts 1, 2 have in the rolled-up state a complementary dovetail shape. The Isolierstegprofile 3, 4 are connected in a known manner with the profile parts 1, 2 by rolling. The profile parts 1, 2 and the Isolierstegprofile 3, 4 limit a (closed) cavity 100th

In that regard, the embodiment corresponds to a conventional composite profile, as shown in Fig. 3.

As shown in Fig. Ia, Ib and 2, the first Isolierstegprofϊl 3, a first side 33 (inside 33), which is turned in the vertical direction y, that is, the second Isolierstegprofil 4 faces. On the inner side 33 of the first insulating strip profile 3, two protruding clip projections 32 are arranged, which extend in the longitudinal direction z. The clip projections 32 are arranged at a distance in the transverse direction x. The clip projections 32 extend with a height h7 in the height direction y from the inside 33, i. here of the central portion 35, the first insulating bar profile. 3

An insulator profile 5 is spaced h5 in the height direction y from the inside 33, i. here of the central portion 35, the Isolierstegprofils 3 arranged. The insulating body profile 5 extends in the longitudinal direction z. The Isolierkörperprofil 5 has a width b4 in the transverse direction x, which is smaller than the width b 1 of the Isolierstegprofils 3.

The Isolierkörperpro fü 5 has on the side facing away from the first Isolierstegprofil 3 page a foam body pan 51 which extends in the longitudinal direction z. The foam body trough 51 has a bottom 54 and two transversely opposed walls 52. The bottom 54 extends in the longitudinal direction z. The bottom 54 has a width b4 in the transverse direction x. The walls 52 of the foam body trough 51 extend from the bottom 54 in the longitudinal direction z. The walls 52 have a height h3 from the bottom of the foam body holding tray 51 in the height direction y. The floor 54 has a wall thickness d3. The walls 52 have a thickness d5, which is preferably equal to d3. The walls 52 are substantially perpendicular, ie, parallel or slightly inclined relative to each other, with respect to the bottom 54 of the foam body holding trough 51.

In the foam body pan 51, a foam body 53 is attached. The foam body 53 extends in the longitudinal direction z. The foam body 53 has a height hl in the vertical direction y. The foam body 53 is connected, for example by direct foaming in the foam body 51 well with this. The shape of the foam body 53 is limited by the bottom 54 and the walls 52 of the foam body 51.

A connecting web arrangement 60 with two connecting webs 61 and a diagonal web 62 is arranged between the insulating body profile 5 and the insulating web profile 3. The connecting web arrangement 60 or the connecting webs 61 each extend in the longitudinal direction z and each have a height h2 in the vertical direction y. The connecting webs 61 have a thickness d4 in the transverse direction x. The connecting webs 61 are arranged in parallel with a distance b3 in the transverse direction x. The connecting webs 61 are connected by the diagonal web 62, which runs diagonally between the connecting webs 61. The diagonal web 62 extends in the longitudinal direction z and over the width b3.

The connecting web arrangement 60 or the connecting webs 61 are connected at their upper edges in the vertical direction y, which face the insulating body profile 5, to the insulating body profile 5. In this embodiment, they are integrally formed with the Isolierkörperprofil 5.

The connecting web arrangement 60 or the connecting webs 61 have clip profiles 63 in the vertical direction y at their lower edges. The clip profiles 63 extend in the longitudinal direction z. The clip profiles 63 are complementary to the clip projections 32 of the first insulating Bar profiles 3 formed. The connecting web arrangement 60 or the connecting webs 61 are connected by the clip profiles 63 with the clip projections 32 of the first insulating web profile 3 by clipping. The height h. 2 is the distance in the vertical direction y between the clip projections 32 and the insulating body profile 5.

The connecting web arrangement 60 connects the insulating body profile 5 with the insulating web profile 3.

A height h5 indicates the distance of the insulating body profile 5 from the inside 33 of the insulating strip profile 3 in the vertical direction y. It is composed of the height h2, i. The height h.5 is thus the extent to which the insulating body profile 5 is separated from the middle section 35 of the insulating strip profile 3 ,

A height h6 indicates the distance of the foam body 53 in from the inside 33 of the Isolierstegprofils 3 in the height direction y.

The connecting web 61 and the Isolierkörperpro fil 5 with the attached thereto foam body 53 have from the inside 33 of the Isolierstegprofils 3 an overall height h4 in the height direction y. This is composed of the height h7 of the clip projections 32, the height h2 of the connecting webs 61, the thickness d3 of the Isolierprofilkörpers and the height hl of the foam body.

To produce an insulating strip according to the first embodiment, the total height h4 of the insulating body must first be determined. The height h3 of the walls 52 is limited in the extrusion of the Schaurnkörperhaltewanne 51 for various reasons such as distortion, the smallest possible wall thickness, etc. The foam body 53 can only be foamed over the walls 52 up to a certain height. This means that the limited height h3 gives a limited height hl. It follows that the height h4 can essentially be set as a parameter advantageously by the heights h7, h2 and d3. After setting the parameters, the first insulating web profile 3, the second insulating web profile 4, the insulating body profile 5 with the connecting web 61, 62 and the foam body holder 51 are produced. Preferably, said parts are extruded and calibrated.

In a further step, the said parts are cut to a length of for example 6m by sawing or cutting.

Subsequently, the foam body 53 is formed in a conventional manner. One possibility is to initially introduce the foam in the foam state 51 in the liquid state. Subsequently, the foam is combined with the simultaneous

Foam holding trough 51 foamed by foaming to form a foam body 53. The foaming takes place in the foam body holding trough 51 without additional limitation. The foam body 53 preferably protrudes beyond the foam holding trough 51 or over the walls 52.

Subsequently or before foaming, the insulating body profile 5 is connected via the connecting webs 61 to the insulating web profile 3 by means of the clip profiles 63 and the clip projections 32. As a result, the insulating body profile 5 and the foam body 53 are connected via the connecting webs 61, 62 with the insulating web profile 3.

To produce a composite profile, the curl projections 31, 41 of the Isolierstegprofile 3, 4 in the receptacles 13, 14 in a conventional manner by rolling the Einrollhammer 1 1, 21 attached. As a result, the firm connection between the profile parts 1, 2 is produced.

Fig. 4 shows a conventional composite profile extending in the longitudinal direction z. The composite profile has the profile parts 1, 2, which are connected in a conventional manner by a first Isolierstegprofil 3a and the second Isolierstegprofil 4. The first insulating web profile 3a has two walls 52a which are perpendicular in the vertical direction y and which delimit a foam body 53a. The walls 52a have a height h9 in the height direction y. The foam body 53a is foamed in a conventional manner between the walls 52a. The foam body 53 a has a height h 10 in the height direction y. As can be clearly seen from a comparison of FIGS. 1a, 1b, 2 with FIGS. 3, 4, the design of the ski body retaining trough 51 and the connecting webs 61, 62 enables combinatorially different insulator heights h4 at freely selectable heights h1 and h6. with freely selectable adaptation to the cavities 100 between the profile parts, a modular system, and highest dimensional accuracy, since parts with different wall thicknesses if necessary. Can be made separately, at the same time very simple foam production.

Fig. 5 shows a second embodiment of the insulating web. Identical components and sizes as in the first embodiment will be referred to below with the same reference numerals and not described again.

The insulating web has, like the insulating web of the first embodiment, an insulating web profile 3 b and an insulating body profile 5b. The insulating web profile 3b and the insulating body profile 5b extend in the longitudinal direction z. The Isolierstegprofil 3b has the width bl in the transverse direction x. The insulator profile has the width b4 in the transverse direction x.

On the inner side 33 of the Isolierstegprofils 3b, which faces the Isolierkörperprofil 5b, a plurality of clip profiles 63 and clip projections 32 are arranged alternately side by side. A clip projection 32 and a clip profile 63 are arranged at the distance b5 in the transverse direction x. In this embodiment, two clip profiles 63 and two clip projections 32 are arranged.

The Isolierkörperprofil 5b is formed except for the connecting webs as in the first embodiment. The insulating body profile 5b has clip profiles 63 and clip projections 32 in the vertical direction y. The clip profiles 63 and clips projections 32 are aligned in the height direction y, opposite the walls 52 of the foam body 51. The clip profiles 63 and clip projections 32 are each arranged alternately side by side in a transverse direction x at a distance b5. In the embodiment shown, two clip profiles 63 and two clip projections 32 are arranged.

A connecting web arrangement 60 with a plurality of parallel arranged connecting webs 61 b and a diagonal web 62 b extends in the longitudinal direction z. The connecting web arrangement 60 or the connecting webs 61b have the height h2. The connection Manure webs 61b are arranged parallel to each other with the distance b5 in the transverse direction x. The number of connecting webs 61b corresponds to the number of clip profiles 63 and clip projections 32 of the insulating body profile 5b or of the insulating web profile 3b. In contrast to the first embodiment, the connecting webs 61b are not integral parts of the insulating body profile 5b. They are integrally connected by a diagonal web 62b in a "package", ie, a separate, inter-connectable component 60b which, when connected to the other components, forms one or more hollow chambers 64 and a stable connection.

The individual connecting webs 61b have a clip profile 63 or a clip projection 32 at both ends in the vertical direction y. The plurality of clip profiles 63 and clip projections 32 is complementary to the clip profiles 63 or clip projections 32 of the insulating body profile 5b or insulating strip profile 3b. The ends of two adjacent on the same side in the vertical direction y connecting webs 61 in the package have a clip profile 63 and a clip projection 32. The package 60b, i. the connecting webs 61b, 62b are connected both to the Isolierkörperpro fü 54 and with the Isolierstegprofil 3 b through the complementary clip profiles 63 and clip projections 32.

During assembly, the components and foam body 53 are manufactured in the same manner as described in the first embodiment.

Insulating bodies with different heights h4 in the height direction y can be produced with this embodiment with the same insulating strip profiles 3b and the same insulating body profiles 5b. For this purpose, connecting webs 61b are produced with different heights h2 in the height direction y, which can be connected to the uniform insulating web profiles 3b and insulating body profiles 5b.

The foam body 53 is then foamed in the frothing cavity bounded by the foam body holding trough 51 and by the lid (EP 1 154 115 A1). For this purpose, an expansion cavity may be provided in the previously Ausschäumhohlraum in an advantageous and known manner, so that the foam can expand without the Isolierkörperprofil 3, 3b to deform.

Foam body 53 may also be aligned obliquely to the height direction y.

The foam body trough 54 may be adapted to the contour of the cavity 100 which is bounded by the profile parts 1, 2 and the Isolierstegprofilen 3, 3b, 4. The foam body holding trough 54 can also be supported on the profile parts 1, 2 and the Isolierstegprofilen 3, 3b, 4. The tie bar assemblies 60, 60b may be configured in a different form. The connecting web arrangements 60, 60b may, for example, have a plurality of diagonal webs 62, 62b, which may also be arranged in different orientations. In the embodiments n connecting webs 61, 61b may be provided. Preferably, the number n is greater than or equal to 2. Preferably, the number n is between 2 and 8, and more preferably between 3 and 6.

By diagonal webs 62, 62b and connecting webs 61, 61b hollow chambers 64 are formed between them. The cavities formed in this or by means of this package form an insulating body.

The connecting bar arrangements may, as in the first embodiment, be formed integrally with the insulating body profile 5. The Verbindungssteganordnungen can also be formed integrally with the Isolierstegprofil and connected to the Isolierkörperprofil by means of clip connection. Advantageously, the Verbindungssteganordnungen are integrally connected at least with the Isolierkörperprofil or Isolierstegprofil.
