Definitions

  • the present invention relates to a composite profile for window, door or facade elements having predetermined fire resistance properties, and a connector and an adapter element for such a composite profile.
  • the fire resistance test prescribes that the structural element will not fail so that the fire resistance compartments are securely separated, and that it will remain air-tight such that the gases generated during a fire are prevented from reaching the side facing away from the fire. It is also important that the temperatures on the side facing away from the fire are not permitted to cause the ignition of easily-ignited materials located there.
  • Aluminum composite profiles are predominantly utilized for the window, door and facade elements. Since the aluminum itself will start to melt at the fire temperatures, a cooling medium (intumescent materials, e.g., gypsum alum, see also, e.g., DE 44 43 762 Al) is often utilized.
  • the aluminum composite profiles are normally comprised of at least two aluminum profile members, the aluminum inner frame and the aluminum outer frame, and one or more insulating strips for thermally separating the aluminum inner frame from the aluminum outer frame.
  • the insulating strips connecting the aluminum inner frame and the aluminum outer frame are normally not exclusively manufactured from thermoplastic synthetic materials. Either the thermoplastic synthetic material is replaced with a non-melting, thermosetting synthetic material, or metal bridges, e.g.
  • Thermosetting synthetic materials have the disadvantage of poor workability.
  • Thermosetting synthetic materials in particular, can be sawed only very poorly when the composite profile must be sawed into segments of specific length during assembly.
  • the use of steel brackets or other metal bridges has the disadvantage of requiring a large amount of manual labour.
  • a further known approach provides the sectional usage of aluminum bridges that conduct a defined amount of heat from the fire side to the side facing away from the fire. It is a disadvantage of this approach that additional mounting portions for connecting the aluminum bridges have to be provided on the aluminum profile members, requiring the manufacturing of modified aluminum systems, resulting in increased costs. In addition, methods of assembly must be modified, and additional processing steps are necessary during the assembly.
  • EP 1 024 243 A2 describes a composite profile having a heat resistant supplemental element in the form of a metal bracket that is adhered to the insulating strip and extends into receiving spaces of the outer profile members in the normal state.

  • EP 0 785 334 A2 describes a composite profile, wherein the outer profile members are connected by insulating strips which are not heat resistant. A heat resistant moulding material is connected to the outer profile members in a form-fitting manner.
  • a composite profile having fire resistance properties is known from DE 44 43 762 Al , wherein the insulating strips are either perforated metal rails or synthetic material rails in which the synthetic material is replaced, in sections, with bridge strips made of metal.

Description

Composite profile for window, door or facade elements having predetermined fire resistance properties, and connector and adapter element for such a composite profile
The present invention relates to a composite profile for window, door or facade elements having predetermined fire resistance properties, and a connector and an adapter element for such a composite profile.
Industrial buildings and public buildings are often subdivided into so-called fire compartments. For this purpose, the doors and windows that are utilized must have fire resistance properties. This is ascertained with a fire resistance test. According to the results of the fire resistance test, a classification into a fire resistance class is performed, e.g., T30, T60, T90. Herein, the alphabetic letter provides the usage (e.g., T = door), and the number provides the length of time in minutes that the structural element has withstood the heat applied thereto during the fire resistance test.
The fire resistance test prescribes that the structural element will not fail so that the fire resistance compartments are securely separated, and that it will remain air-tight such that the gases generated during a fire are prevented from reaching the side facing away from the fire. It is also important that the temperatures on the side facing away from the fire are not permitted to cause the ignition of easily-ignited materials located there.
Aluminum composite profiles are predominantly utilized for the window, door and facade elements. Since the aluminum itself will start to melt at the fire temperatures, a cooling medium (intumescent materials, e.g., gypsum alum, see also, e.g., DE 44 43 762 Al) is often utilized. The aluminum composite profiles are normally comprised of at least two aluminum profile members, the aluminum inner frame and the aluminum outer frame, and one or more insulating strips for thermally separating the aluminum inner frame from the aluminum outer frame. In applications having fire resistance properties, the insulating strips connecting the aluminum inner frame and the aluminum outer frame are normally not exclusively manufactured from thermoplastic synthetic materials. Either the thermoplastic synthetic material is replaced with a non-melting, thermosetting synthetic material, or metal bridges, e.g. steel brackets, are utilized at least in sections. Thermosetting synthetic materials have the disadvantage of poor workability. Thermosetting synthetic materials, in particular, can be sawed only very poorly when the composite profile must be sawed into segments of specific length during assembly. The use of steel brackets or other metal bridges has the disadvantage of requiring a large amount of manual labour.
A further known approach provides the sectional usage of aluminum bridges that conduct a defined amount of heat from the fire side to the side facing away from the fire. It is a disadvantage of this approach that additional mounting portions for connecting the aluminum bridges have to be provided on the aluminum profile members, requiring the manufacturing of modified aluminum systems, resulting in increased costs. In addition, methods of assembly must be modified, and additional processing steps are necessary during the assembly.
EP 1 024 243 A2 describes a composite profile having a heat resistant supplemental element in the form of a metal bracket that is adhered to the insulating strip and extends into receiving spaces of the outer profile members in the normal state.
EP 1 182 317 A2 describes a composite profile having fire resistance properties,wherin the insulating strip is comprised, in sections, of metal instead of a thermoplastic synthetic material.
EP 0 785 334 A2 describes a composite profile, wherein the outer profile members are connected by insulating strips which are not heat resistant. A heat resistant moulding material is connected to the outer profile members in a form-fitting manner.
A composite profile having fire resistance properties is known from DE 44 43 762 Al , wherein the insulating strips are either perforated metal rails or synthetic material rails in which the synthetic material is replaced, in sections, with bridge strips made of metal. A fire resistance strip may be provided on an insulating strip.
Further composite profiles having fire resistance properties are known from EP 1 327 741 A2 and DE 44 04 565 CI.
It is an object of the invention to provide a composite profile for window, door or facade elements having predetermined fire resistance properties, and a connector and an adapter element for such a composite profile, which allow for a secure connection of the outer profile members in case of a fire without requiring a modification the outer profile members, resulting in additional costs.
This object is achieved by a composite profile according to one of claims 1 , 12, 13, a connector according to claim 6, and an adapter element according to claim 10.
Further developments of the invention are recited in the dependent claims.
By providing an adapter element having engagement portions for connecting the outer profile members through a fireproof connecting element between conventional outer profile members and conventional insulating strips, conventional aluminum systems can be connected in a fireproof manner without any modifications. Further, no additional processing steps are necessary during the assembly of the composite profile.
Preferably, the synthetic material insulating strips and the adapter elements are extrusion components, wherein the adapter elements are preferably formed as aluminum adapters made of a softer alloy than the aluminum profile members. This allows for a simple manufacturing process without the need for additional finishing processes, and a smooth assembly of the composite profiles.
Further advantages and purposes are derivable from the description of the exemplary embodiments in view of the Figures. In the Figures:

Fig. 8 shows part of another composite profile having fire resistance properties.
Fig. 1 shows, in a cross-sectional view perpendicular to a longitudinal direction z, a composite profile according to an embodiment of the invention, e.g., for a door leaf frame.
The composite profile includes a first outer profile member 1 and a second outer profile member 2 which extend in the longitudinal direction z. The outer profile members 1 and 2 are aluminum profiles. Herein, outer profile member denotes a profile member that is disposed on an outer side of the composite profile, such as e.g., an inner frame or an outer frame. Even if the composite profile is built into a room on both sides, as in doors between inner rooms of a building, then the outer profile members are nevertheless disposed on an outer side. The outer profile members can be made of another metal, such as steel, or a heat resistant synthetic material, such as a suitable thermosetting plastic.
The two aluminum profile members 1 , 2 are connected through a connector 10 that extends in the longitudinal direction z, wherein an intermediate space 4 is formed between the outer profile members 1, 2. The connector 10 includes adapter elements 16, 17, 18, 19 which serve as adapters and extend in the longitudinal direction z, and a connecting element 15 that extends in the longitudinal direction z, wherein the adapter elements and the connecting element may be made of the same materials as the outer profile members. The connector 10 further includes insulating strips 13a, 13b made of a thermoplastic material having low heat conductivity, such as e.g., PA6, which extend in the longitudinal direction z. The insulating strips 13a, 13b may also be manufactured from other materials suitable for forming insulating strips for the thermal separation of the outer profile members of window, door or facade elements, such as PA66 or PA66 with glass-fiber reinforcements (e.g., PA66GF25) or the like. PA66 has a melting point of about 260° Celsius.
So that the door will not fail in case of a fire, in that the outer profile members 1 , 2 are not mechanically held together due to melting of the insulating strips 13 a, 13b, the connecting element 15 is provided, which is in durable engagement with the outer profile members via the adapter elements 16, 17 and fixedly and durably connects the outer profile members and holds them together even if the insulating strips 13a, 13b melt. So that the insulating properties of the composite profile in the normal state can be assured, the length of the heat transfer path via the connecting element 15 is greater than the length of the heat transfer path via the insulating strips 13a, 13b. Preferably, the length of the heat transfer path via the connecting element is at least two times the length of the heat transfer path through one of the insulating strips. In the embodiment shown in Fig. 1 , the length of the heat transfer path via the connecting element 15 is more than three times the length of the heat transfer path through one of the insulating strips 13a, 13b.
As discussed above, the connector 10 includes the four adapter elements 16, 17, 18, 19. The adapter element 16 includes, on a side facing the first outer profile member 1, a first connecting portion 16c for connecting the adapter element 16 to the outer profile member 1 by rolling-in. For this purpose, the rolling-in hammer of the outer profile 1 is pressed towards an abutment thereof (rolled-on), and the connecting portion 16c (here, a swallow-tail shaped rail) is rolled- in in a known manner. On the side opposite to the connecting portion 16c, the adapter element 16 includes a second connecting portion 16b, 16d for connecting the adapter element 16 to the insulating strip 13a. The connection of the insulating strip 13a to the adapter element 16 is made in the same fashion as the connection of the adapter element 16 to the outer profile member 1 , i.e., by rolling-in a connecting portion 13e (here, a swallow-tail shaped rail) of the insulating strip 13a, wherein a rolling-in hammer 16d of the adapter element 16 is pressed towards an abutment 16b of the adapter element 16.
The end of the insulating strip 13a that is not connected to the adapter element 16 is also connected to the adapter element 18 by rolling-in a connecting portion 13e (here, a swallow-tail shaped rail), wherein the adapter element 18 also includes a first connecting portion 18c for connecting to the outer profile member 2 and a second connecting portion 18b, 18d for con- necting to the insulating strip 13a. The first connecting portion 18c (here, a swallow-tail shaped rail) is connected to the second outer profile member 2 by rolling-in, as described above.
In addition to the connecting portions 16b, 16c, 16d, the adapter element 16 includes an engagement portion 16a that projects from the adapter element 16 in a height direction y perpendicular to the longitudinal direction z and extends parallel to the outer profile member 1 herein. In a cross-sectional view, the engagement portion 16a includes a rounded head and projections that project towards the sides and serve as barbs and/or latching or locking elements.
In the present embodiment, the connecting element 15 is formed as a metal bracket, preferably made from aluminum or, in the alternative, made of steel or another metal. As an alternative, the connecting element 15 may also be comprised of glass fibers or the like. The connecting element 15 has an S-shape in a cross section perpendicular to the longitudinal direction z, wherein two sections, which extend parallel to the outer profile members 1 , 2 in the height direction y, are connected by a section which extends in the transverse direction x perpendicular to the height direction y and to the longitudinal direction z. A first engagement portion 15a is formed on a first end of the connecting element 15. The engagement portion 15a is complementary to the engagement portion 16a of the adapter element 16, so that the first engagement portion 15a can engage the engagement portion 16a for a fixed and durable connection therewith, e.g., by sliding the first engagement portion 15a onto the engagement portion 16a and latching or catching of the same.
On the second end, the connecting element 15 includes a second engagement portion 15b formed identical to the first engagement portion 15a. The second engagement portion 15b is fixedly and durably connectable/connected to the adapter element 17 in the same manner, wherein the adapter element 17 also includes a first connecting portion 17c and a second connecting portion 17b, 17d. The adapter element 17 is formed identical to the adapter element 16. Further, the adapter element 17 is durably connectable/connected to the second outer profile member 2 by rolling-in, in the same manner in which the adapter element 16 is connectable/connected to the first outer profile member 1. One end of the insulating strip 13b is connectable/connected to the second connecting portion 17b, 17d of the adapter element 17 by rolling-in. The other end of the insulating strip 13b is connectable/connected to the adapter element 19 by rolling-in, wherein the adapter element 19 is formed identical to the adapter ele- ment 18. The adapter element 19 is durably connectable/connected to the first outer profile member 1, analogous to the adapter element 18. In this manner, the first and second outer profile members 1 , 2 are fixedly and durably connectable/connected by the connector 10 with the intermediate space 4 formed between them, wherein thermal conduction between the first and second outer profile members 1 , 2 is relatively low due to the low heat conductivity of the insulating strips 13 a, 13b.
The connecting element 15 may extend in the longitudinal direction z continuously with length lo or only sectionally, i.e., in the form of a plurality n of connecting elements 15, each having a length li in the longitudinal direction z. An adjustment of the total length, that is e.g., 10 or n li, of the connecting element or the plurality of connecting elements 15 allows for setting a defined heat transfer from the fire side to the side facing away from the fire in case of a fire. The heat transfer results in a cooling of the outer profile member on the fire side and thus in a longer useful life of the composite profile in case of a fire.
The form of the engagement portions 15a, 15b of the connecting element 15 and of the engagement portions 16a, 17a of the adapter elements 16, 17 is interchangeable. In other words, the engagement portions 15 a, 15b may be formed similar to the engagement portions 16a, 17a, and, accordingly, the engagement portions 16a, 17a may be formed similar to the engagement portions 15a, 15b. Further, the engagement portions 15a, 15b, 16a, 17a may have another form which allows for a secure and durable connection of the connecting element 15 to the adapter elements 16, 17.
Fig. 2 shows a modification of the composite profile of Fig. 1. Like parts are designated by like reference numerals. The composite profile frame shown in Fig. 2 differs from the composite profile frame of Fig. 1 in that the adapter elements 16, 17, 18, 19 are formed differently. While each of the rolling-in hammers 16d, 17d, 18d in Fig. 1 is disposed in the intermediate space 4 when the connector 10 is installed, in the modification shown in Fig. 2, each of the rolling-in hammers 16d, 17d, 18d is formed on the other side, i.e., the outer side, and the abutments 16b, 17b, 18b are disposed in the intermediate space 4. Fig. 3 shows another modification of the composite profile of Fig. 1. In the modification shown in Fig. 3, the adapter elements 16, 17, 18, 19 each include two rolling-in hammers 16d, 17d, 18d instead of a single rolling-in hammer 16d, 17d, 18d and a single abutment 16b, 17b, 18b.
Fig. 4 shows another embodiment of a composite profile. Like parts are again designated by like reference numerals.
In the embodiment shown in Fig. 4, two connectors 10 which extend in the longitudinal direction z are provided. The connectors 10 differ from the connectors described above in that each connector is formed by a connecting element 15 and a corresponding insulating strip 13c and two adapter elements 16, 17, instead of being formed by a connecting element 15, two insulating strips 13a, 13b, and four adapter elements 16, 17, 18, 19. As shown in Fig. 4, an engagement portion 16a, 17a extends into the intermediate space 4 from each of the adapter elements 16, 17, and the first connecting portion 15a and the second connecting portion 15b of the connecting element 15 are in engagement with the engagement portions 16a, 17a in the manner described above. Between the first engagement portion 15a and the second engagement portion 15b, the connecting element 15 includes a section that extends in the transverse direction x. The connection of the outer profile members 1 , 2 by two connectors 10 spaced apart in the height direction y improves the secure and durable connection of the outer profile members 1 , 2.
Fig. 5 shows a modification of the composite profile of Fig. 4.
In the composite profile shown in Fig. 5, only one of the connectors 10 of Fig. 4 is provided. The second insulating strip for the connection of the outer profile members 1 , 2 is a conventional insulating strip 13d that is connected to the first and second outer profile members 1, 2 by rolling-in in a conventional manner.
Fig. 6 shows another modification of the composite profile shown in Fig. 4.
In Fig. 6, the section connecting the first engagement portion 15a with the second engagement portion 15b of one of the connecting elements 15 is convex, i.e., formed such that it bulges into the intermediate space 4 provided between the outer profile members 1, 2, so that a cavity lOh defined by the insulating strip 13c, the adapter elements 16, 17, and the connecting element 15 is enlarged. A foam material 20 may be filled into the cavity 1 Oh formed in such a manner. In this manner, a reinforcement element for reinforcing the composite profile frame of Fig. 6 may be formed. Further, the foam material improves the thermal separation of the first and the second outer profile members.
Fig. 7 shows another modification of the composite profile of Fig. 1.
In Fig. 7, the adapter elements that are not in engagement with the connecting element 15 are omitted. This results in a reduction of the number of parts used and improves the thermal separation of the first outer profile member 1 and the second outer profile member 2.
In the embodiments of the composite profile shown in Figs. 1 to 7, the connecting element 15 is always in engagement with the adapter elements 16, 17 when the outer profile member 1 and the outer profile member 2 are connected through the connector 10. EP 2 136 024 Al discloses a composite profile, wherein a connecting element 15 only connects outer profile members 11 , 12 of this composite profile in case of a fire. This is described in the following with reference to Fig. 8.
An insulating strip 23 that connects the outer profile members 1 1 , 12 includes an insulating strip body 23 k that extends in the longitudinal direction z and has a width b in a transverse direction x perpendicular to the longitudinal direction z and a minimum thickness in a height direction y perpendicular to the longitudinal direction z and the transverse direction x. Connecting elements 23v are provided on the longitudinal edges of the insulating strip 23, which are spaced from each other in the transverse direction x, for connecting the insulating strips with the first and second outer profile members 1 1, 12. The connection takes place, e.g. by rolling-in into the recess 12c. For this purpose, the rolling-in hammer 12e is pressed towards the abutment 12f (rolled-on), and the connecting element is rolled-in in a known manner. Guide walls 23a, 23b are provided parallel to each other and with a predetermined spacing c of the inner sides of the guide walls that face each other at least in segments of the insulating strip 23 in the longitudinal direction z; the guide walls 23a, 23b project from the insulating strip body 23k in the height direction y. The guide walls 23a, 23b can also be formed continuously in the longitudinal direction z. The connecting element 15 has a U-shape in the cross section perpendicular to the longitudinal direction z, wherein the legs 15s, 15s of the U-shape extend in parallel and along the longitudinal direction z. A first engagement portion 15a is formed on the free end of one leg 15s. A correspondingly-formed second engagement portion 15b is formed on the other leg 15s. The first engagement portion 15a and the second engagement portion 15b are separate from each other in the transverse direction x.
The outer profile member 1 1 includes a projection on which a third engagement portion 11a, which is complementary to the first engagement portion 15a, is provided. In an analogous manner, a second projection having a fourth engagement portion 12b, which is complementary to the second engagement portion 15b, is formed on the second outer profile member 12. In addition, the outer profile member 1 1 is connected to the outer profile member 12 by means of a conventional insulating strip.
The outer sides of the legs 15s have a spacing from each other that corresponds to the spacing c of the inner sides of the walls 23a and 23b of the insulating strip 23 with the tolerance necessary for a sliding movability of the connecting element 15 between the walls 23a and 23b. The walls 23a and 23b, which extend in the longitudinal direction z and in parallel to each other, project in the height direction y perpendicular to the transverse direction x. As a result, they can guide the outer profile member connecting element 15 during a movement in the height direction y, having the tolerance necessary for a sliding movement.
The guide walls 23a and 23b, together with the insulating strip body 23k, form a kind of longitudinal trough. An actuating member 26 is disposed on the bottom of this longitudinal trough between the guide walls 23a and 23b. In this embodiment, the actuating member is formed by a self-adhering tape having an epoxy-resin-bound intumescent layer 26a and a self-adhering layer 26b. The actuating member 26 has the form of a self-adhering heat resistant strip. The expoxy-resin-bound intumescent product comprises thermally-expanding components, flame resistant agent and additive. At a temperature of about 200° Celsius, the epoxy-resin-bound intumescent product begins to expand (foam up) and achieves an up-to-20-fold volume increase during a corresponding exposure to heat in case of a fire. Preferably, the heat resistant strip comprises, e.g., a material that releases water by means of a phase transition, so that a cooling is also achieved. A typical thickness is, e.g., 5 mm, so that theoretically up to a 100 mm actuating distance can be achieved with this embodiment of the actuating member 26, depending on the counteracting force,.
As can be easily recognized from Fig. 8, a corresponding volume increase of the layer 26a leads to the outer profile member connecting element 15 being actively moved in the height direction y, towards the third engagement portion 1 la and the fourth engagement portion 12b. As can also be easily envisioned, this leads to an active movement of the first engagement portion 15a into engagement with the third engagement portion 1 1a, and to an active movement of the second engagement portion 15b into engagement with the fourth engagement portion 12b.
In alternative to the adhesive tape having the intumescent product that swells up when exposed to heat, other actuating members are possible, such as bimetal strips or other bimetal elements that bend when exposed to heat and thus apply the actuating force. Other materials that emit gas when exposed to heat, which materials are embedded in the actuating member and then generate the actuating movement through the pneumatic action of the escaping gases, are possible, as well as other actuating members triggered by an exposure to heat.
Now, a modification of the embodiment shown in Fig. 5 is described with reference to Fig. 5 and Fig. 8. Herein, the insulating strip 23 having the connecting element 15 and the actuating member 26 is provided in place of the insulating strip 13d of Fig. 5. The engagement portions 16a, 17a of the adapter elements 16, 17 are formed in an analogous manner to the engagement portions 1 la and 12b shown in Fig. 8 and are aligned with the engagement portions 15a, 15b of the connecting element 15. It is obvious that the shapes of the corresponding engagement portions are interchangeable. In this manner, the above-described effect can also be achieved in the modification of the embodiment shown in Fig. 5.
As an alternative, in a further modification of the embodiment shown in Fig. 5, the insulating strip 23 of Fig. 8 is provided in place of the insulating strip 13c. In this modification, the engagement portions 17a, 17b are formed on a portion of the adapter elements 16, 17 that extends beyond the guide walls 23a, 23b, analogous to the engagement portions 11a, 12b formed on the outer profile members 1 1 , 12 in Fig. 8. As an alternative to the S-shaped or U-shaped connecting elements 15 shown herein, other shapes of the connecting elements 15 are contemplated, e.g., a meandering shape or plural S- shaped sections disposed in series.
In the composite profile, other measures for improving the fire resistance properties can also be provided, such as cooling fire resistance elements, etc. It is particularly advantageous to use a cooling intumescent product that can be simultaneously used as an actuating member by means of a volume increase.
The use of a connecting element made of aluminum, together with adapter elements made of aluminum, makes it possible to saw the composite profile in a known manner during the finishing process.
With the use of the adapter elements formed as adapters, there is no need to alter conventional aluminum composite profile members. Further, their depth can be varied by using different insulating strips, with the adapter elements always having the same form. The use of extrusion components allows for a simple manufacturing process without the need for additional finishing processes. The use of the adapter elements, in particular, makes it possible to avoid additional manufacturing costs for the manufacturer of the aluminum outer profile members.
The use of a slidingly flexible insulating strip (known, e.g., from DE 20 2007 016 649 Ul), as well as an engagement of the connecting element with the adapter that is slidably flexible at least on one side, allows for a slidably flexible structure of the composite profile.
In order to improve the connection of the adapter elements to the outer profile members, the adapter elements may be milled. Further, the adapter elements may be manufactured from a softer alloy than the outer profile members. For a further increase in the strength of the connection between the adapter elements and the outer profile members, wires may also be provided.
The latching of the connecting element may also be achieved through the use of aluminum brackets, sheet metal brackets, wire elements, or framework components. The synthetic material insulating strips may have a connecting portion with a shape that is different from a swallow-tail, e.g., rectangular shapes, polygon shapes, etc.
The connection of the insulating strips to the adapter elements may be designed to be variable. In this manner, synthetic material insulating strips which cannot be rolled-in can also be used for the composite profile. They may be connected to the adapter elements by means other than rolling-in, e.g., casting, gluing, extruding onto, etc. Further, the connection of the connecting element with the adapter elements may be designed to be variable, e.g., by using a process for connecting the same that is selected from one of latching, rolling-in, press-fitting, clamping, gluing, welding, screwing, riveting, or any combination thereof.
