Abstract

A heat insulating profile consists of: (a) a primary profiled section (20a, 20b) made of a material with low thermal conductivity, especially plastic; and (b) at least one secondary profiled section (30) composed of a non-combustible material. Each of the primary profiled sections is connected to at least one secondary profiled section in a longitudinal direction. A band extends longitudinally along the profile and joins the primary and secondary sections.

Description

The invention relates to a thermal insulation profile for Fire protection constructions for attachment between two in Distance between metal profiles, in particular for facades, windows and doors.

In the formation of frames in the area of windows, doors and facades for the lowest possible heat conduction between the outward and the inward Areas of a frame. This will be ensures that for reasons of strength necessarily used through metal profiles Plastic strips are connected together along that their longitudinal edges so widened, for example with a dovetail, hammer head, or the like, that they are equipped in a respective Bracket contour of a metal profile can be inserted and in a direction perpendicular to the longitudinal extension in the Bracket contour can be anchored.

For such frame arrangements there are fire protection requirements to consider. In particular, it must be ensured that in a fire if the plastic of the insulating bridge is the heat development fails at a certain point in time, the metal profiles held by the plastic profile are not can separate from each other.

State of the art

DE 44 43 762 A1 is a multi-part insulating strip known to meet the above requirements between two metal profiles can be used. The Plastic strip is along the longitudinal edges, i.e. in the widened areas, cut out in sections. In these Recesses are corresponding sections of the Plastic bar bridging metal bar used. in the Fire takes over after the failure of the plastic areas the bridging metal bar over the entire length Holder function. In order to nevertheless conduct heat between the to minimize metal profiles arranged inside and outside, the metal bar is made of a material with reduced Thermal conductivity trained.

Furthermore, glass fiber reinforcements are known in the art in a thermal insulation strip designed in the manner described are made of plastic. such Glass fiber reinforcements are expensive, on the one hand, and on the other hand arise during the formation of a plastic insulation strip Machinability problems caused by cutting Method. The tools used wear out due to the resistant glass fiber reinforcements very quickly, so that the economics of making such a Thermal insulation strip made of plastic is significantly reduced.

DE 19 900 793 A1 describes a thermal insulation profile which is provided with a heat-resistant additional element, which is in the installed state in from the mounting grooves Metal profiles separate receiving spaces for the metal profiles extends. This measure allows the unwanted heat flow between the metal profiles decrease; however, there are additional recording areas for to provide the additional elements made of metal.

DE 34 38 861 A1 relates to a thermal insulation profile for Fire protection structures that between the metal profiles conventional insulating bars arranged and in addition at least one of the isolating webs or in the Insulating webs has an integrated bridging element. The Bridging links can be spaced apart arranged short pieces exist. Alternatively, the Bridging links but also in one piece on the length of the Go through composite profile. The insulating bars consist of a material with low thermal conductivity and the Bridging elements consist of a non-flammable Material.

Presentation of the invention

The invention has for its object a thermal insulation profile to propose for fire protection constructions that simple is constructed and easy to assemble.

This problem is solved by a thermal insulation profile for fire protection constructions with the features of the claim 1 or 9.

The invention is based on the idea of a thermal insulation profile for mounting between two at a distance from each other arranged metal profiles so that the strip-shaped thermal insulation profile from a plurality of first Profile sections and at least a second Profile section exists. The first profile sections exist made of a material with low thermal conductivity, especially plastic, while the at least one second profile section made of a non-combustible material exists or contains a non-combustible material. The Arrangement of the first and second profile sections to each other takes the form that this in the longitudinal direction of the Thermal insulation profile arranged to each other and with each other are connected. In other words, one strip-shaped thermal insulation profile a sequence of first and second profile sections provided in the longitudinal direction.

The connection between the first profile sections and second profile sections can be done by at least one continuous band is provided that in The longitudinal direction of the thermal insulation profile extends and the first and connects the second profile sections together. Alternatively, the connection between the first and second Profile sections with the help of mounting tabs. Here, every second profile section has two Fastening tabs that extend from the longitudinal end faces of the second profile section starting in the longitudinal direction extend and in appropriately shaped receiving areas of the first profile sections are attachable.

Preferred embodiments of the invention are characterized by the other claims marked.

According to a preferred embodiment, this can at least a longitudinal band made of metal and Have recesses, preferably in the longitudinal direction arranged holes. This measure will, without the desired holding function to impair the heat conduction reduced in both the longitudinal and transverse directions of the insulation strip.

According to an alternative preferred embodiment, this is at least one tape a plastic tape or a Fiberglass tape. These two alternative embodiments use a lower material for each band Thermal conductivity so that the thermal insulation profile can be optimized thermally. Both that Glass fiber tape as well as the plastic tape must be in the Fire do not take on strength functions, as this completely from the second profile sections from a not flammable material.

According to an alternative embodiment, there is at least one band made of intumescent material. Intumescent material has a heat-consuming effect and reacts to the greatly increased in the event of fire Temperatures with foaming. With a tape Intumescent material can therefore be used in the event of a fire Absorb heat and secondly, depending on the arrangement of the Thermal insulation profile, for example a gap between the Seal metal profiles or one of thermal insulation profiles foam out the limited chamber.

Preferably, the thermal insulation profile is only one continuous band on one long side of the thermal insulation profile Mistake. A single band can be sufficient Grant strength so that the thermal insulation profile consisting of the sequence of first and second profile sections, in corresponding receiving sections of the metal profiles can be inserted without the individual band connected profile sections separate from each other.

The tape or tapes can be on one long side of the Thermal insulation profile may be provided overlying or in a Be integrated along the length of the thermal insulation profile.

When designing the second profile sections with Fastening tabs are preferred Embodiment in milling of the first profile sections inserted. In this way, the connection between perform the first and second profile sections very easily and also make sure that the profile sections in the the correct position to each other and to each other get connected.

The fastening tabs are preferably with the first Profile sections screwed or riveted.

According to an alternative embodiment of the invention the fastening tabs of the second profile sections in the first profile sections hot pressed. The advantage of this Thermal insulation profile is in the manufacturing area. By pressing in the fastening tabs of the second Profile sections in the not yet hardened material of the first profile sections after leaving an extruder will be a very easy to do though viable connection created without separate Fasteners are needed.

According to a preferred embodiment of the invention the at least one second section from a stamped and bent part made of steel or stainless steel, extruded aluminum or Ceramics.

Each of the first sections preferably consists of one Plastic from the group comprising ABS, polypropylene and glass fiber reinforced polyamide 6.6 is selected.

According to a preferred embodiment of the invention the thermal insulation profile receiving sections for attachment between metal profiles. Every second profile section owns at least in the area of this Receiving sections opposite to the adjacent first Profile section / profile sections a reduced contour. A reduced contour is understood here to mean that the cross-sectional area of the second profile sections at one Section perpendicular to the longitudinal extent of the thermal insulation profile in the area of the receiving sections is less than that Cross-sectional area of the first profile sections. simultaneously no second section of the profile rises above that of the or the adjacent first profile sections formed Lateral surface around the receiving sections. By the second profile sections in the recording area is a slight misalignment of the first relative to the second profile sections at their Attachment tolerable as it doesn't get caught or difficult insertion of the thermal insulation profile into the Receiving sections of the metal profiles comes.

According to an alternative, preferred embodiment of the Invention is every second profile section as a plastic part with a heat-resistant insert, preferably made of metal or ceramic. Every second profile section has the same at least in the area of the receiving sections Contour like the first profile sections. Through these measures can the undesirable heat conduction in the area of reduce the second profile sections significantly, because the In the event of fire, the heat-resistant holding function is assumed Deposits are arranged around a plastic layer that with the receiving sections of the inner profile and the receiving profile is in contact. By this measure it is also not required direct contact between the second Profile sections and the recording rooms of the to be connected Avoid profiles. The same material can be used as plastic as used for the first profile sections and the Metal insert as part of the production with this plastic be encapsulated.

Ways of Carrying Out the Invention

In the following figures, identical or mutually corresponding components with the same reference numbers be designated.

FIG. 1 shows a generally with reference number 10 designated thermal insulation profile 10. The thermal insulation profile is generally also as an insulating bridge or fire protection strip denotes and has an elongated shape with two in Longitudinal receiving regions 12 which in all the following exemplary embodiments only are exemplary and the inclusion in accordingly shaped profiles by the Thermal insulation profile 10 serve to connect metal profiles. Instead of the one shown in FIG. dovetail geometry is also different Forms conceivable that the desired form fit between the receiving areas 12 and the corresponding ensure shaped metal profiles.

The thermal insulation profile 10 consists of several first Profile sections 20 or in the illustration according to FIG. 1 (20a and 20b), and at least a second Profile section 30 which in the longitudinal direction of the Thermal insulation profile 10 between the first profile sections (20a and 20b) is arranged. As indicated in FIG. 1, the second profile section 30 essentially has the same cross-sectional shape as the adjacent first Profile sections (20a and 20b), deliberately on in Figure 1 the representation of those described below Attachment alternatives for connecting the first and second Profile sections has been dispensed with. Figure 1 also shows only a short section of a thermal insulation profile where themselves at regular or irregular intervals Alternate first and second profile sections.

The first profile sections are made of plastic, whereby ABS, polypropylene or polyamide 6.6 with glass fiber reinforcement to be favoured. The first sections are made of plastic above all, the heat conduction between the To keep the inner profile and outer profile as low as possible. There the first profile sections in the event of a fire due to the Temperature behavior of plastic its strength lose because the plastic softens, melts or even burns, the second sections are also provided, which are the fire protection properties of the thermal insulation profile to ensure. The second sections are non-flammable and made of metal (steel, stainless steel, aluminum, brass) or Ceramic made.

FIG. 2 shows a section of a thermal insulation profile 10 a first embodiment of the invention, in which the Connection between the second profile section 30 and the first Profile sections (20a, 20b) via a metal strip 24, that is continuous over the length of the thermal insulation profile 10 extends and is mounted in an area between the receiving areas 12. In the embodiment according to Figure 2 is the metal band 24 at first Profile sections as well as second profile sections applied, for example glued on. This form of The surface-mounted attachment of the metal strip 24 is shown in FIG. 3a and shown in Figure 3b, with corresponding in Figure 3a the embodiment of Figure 2 only a single metal strip is attached to one side and in the embodiment 3b two metal strips (24a and 24b) each opposite sides of the thermal insulation profile 10 attached are.

For the heat conduction across the metal strip 24 Possibility to reduce, the metal band can punch out 26, while geometry and arrangement along the Metal strip 24 is shown in FIG. 5 only as an example and can of course be arbitrary. Another possible embodiment, which is not in the figures is shown consists of one or two metal strips to provide that not on the profile sections is or are placed on top, but in appropriate recesses is inserted. It is thus in both the first and second Profile sections provided a recess that after arranging the first and second side by side Profile sections are aligned with each other so that a continuous recess for inserting a metal band forms.

It is also conceivable that the band 24 is not only in the Middle area of the thermal insulation profile between the Recording areas extends, but used as masking tape and the intermediate part through the connection serving masking tape is laminated.

An alternative embodiment of the invention consists in the Provide mounting tabs on the second Profile sections so that every other profile section individually with two adjacent first profile sections is connectable. 1 shows a possible embodiment a second profile section 30 with molded thereon Fastening tabs 28 shown, the two Mounting tabs each in the longitudinal direction of the Basic body of the second profile section and, in Embodiment according to Figure 5, are arranged so that with the side wall 32 facing the viewer in one Complete level. When designing the second 5 are the profile section Mounting tabs (28) in recesses in the adjacent first profile sections inserted and in a suitable manner connected.

The connection between the first and second profile sections done by the mounting tabs 28 in corresponding Milled out of the plastic profile are inserted and then connected to the first profile sections are, for example, glued, screwed, or riveted become hot, or in the first profile sections be pushed in.

An alternative to the embodiment according to FIG. 5 is also one Design conceivable according to Figure 6, in which the One-piece mounting tabs (28a and 28b) 28 are formed, as it were like a continuous belt over the side wall 32 of the second profile section is arranged. The two fastening tabs (28a and 28b) forming band 28 can be integral with the second Profile section be formed or in a suitable manner be connected to the second profile section. The advantage the configuration of the second profile section according to FIG. 6 is that the first to be connected Profile sections no special adjustments with regard to the geometry must be provided, since the first one is adjacent Profile sections the mounting tabs (28a and 28b) themselves extend over the side wall and in a suitable manner with this can be connected. So they can Mounting tabs 28, for example, with the first Profile sections can be glued or via a Screw or rivet connection to be connected to these.

In the embodiment of Figure 7, the side view represents a thermal insulation profile, as can be seen from Figure 7 28, holes 34 are in the fastening tabs provided that serve to accommodate a screw or rivet can. When the fastening tabs are pressed in hot the not yet hardened plastic material of the first Profile sections can also be the holes 34 or also differently shaped punchings on the fastening tabs be advantageous to the positive connection between the fastening tab and the plastic material improve. When using the holes 34 for recording a screw can be on the opposite side of the Thermal insulation profile also a recess in the first Profile sections can be provided to accommodate a Allow countersunk head for a screw connection.

Figure 9 also shows a side view of a Thermal insulation profile 10, in which the second profile section molded mounting tabs 28 according to the Representation according to Figure 5. From the sectional view along the section line B-B shown in Figure 10 , it can be seen that the fastening tab 28 in one Depression of the first profile section 20b is inserted and essentially flush with the side wall 32.

Possible embodiments are shown in FIGS. 11a to 11c for the design of the second profile section 30 as Stamped bent part shown. The stamped and bent part can for example made of steel, stainless steel or brass or one other suitable metal or a metal alloy consist. To the heat conduction in the area of the second To reduce profile section 30, this can, as in Figure 12 is shown, one or more punched have. In the exemplary embodiment according to FIG. 12 as well Figure 13 is punched out as hole 26 in the second Profile part designed. To connect with the adjacent first profile sections to be attached (not shown) are also the alternatives mentioned above Fastening options conceivable. For example, that stamped and bent part shown in Figure 12 using a metal band with the first to be attached Profile sections are connected while at the Embodiment according to Figure 13 mounting tabs 28 on second profile section 30 are provided, optionally with Bores 34 are provided. The illustration according to FIG. 13 is only one possible embodiment in which the side wall 32 of the second profile section 30 with the end wall of the Fastening tabs 28 are aligned. This embodiment is comparable to that shown in FIGS. 5 and 9 Embodiments either in conjunction with a accordingly shaped milling in plastic body of the to use first profile sections or will in that yet uncured plastic material of the first Profile sections pressed in. In the same way it is naturally also with a second profile section conceivable according to Figure 13, the mounting tabs 28 via a Bending fold in a parallel plane that is above the Drawing plane according to Figure 13 and the attachment of first and second profile sections corresponding to the Representation according to Figures 6 to 8 allowed.

FIG. 14 shows a further variant of a thermal insulation profile with a second profile section 30 made of extruded Aluminum or a ceramic molding. at In this embodiment, the mounting tabs 28 can the two long sides of the with a punched out 26th provided base body from the extruded aluminum rod be milled out. Different from the previously shown The fastening tab 28 can be embodied here centered in the cross section of the second profile section 30 be arranged, as can be seen from Figure 15, the one Side view of the second shown in Figure 14 Profile section is. The mounting tabs 28 are at this embodiment arranged so that the one slit-shaped depression in the adjacent first Profile sections inserted or not yet hardened plastic material can be pressed in.

That which can also be seen from the sectional illustration in FIG. 16 Punch 26 can have a different geometry and besides the rectangular shape according to FIG. 17b also circular (Figure 17a) or in the form of two upside down to each other arranged, trapezoidal punched out.

FIG. 18 shows a further embodiment of the invention and provides a section through a second profile section 30 with a first profile section 20 attached to it. As can be seen from the illustration in FIG. 18, the Contour of the second profile section 30 in the Recording areas 12 slightly smaller than that of first profile sections 20. This has the advantage that the second profile section is not in the reception zone of the two metal half-shells to be connected to one another, because the guide when inserting the thermal insulation profile formed exclusively by the first profile sections 20 becomes.

Another advantage of using two profile sections with a slightly smaller contour is that in the contact zones of the metal half-shells no contact and thus no heat conduction takes place. By this measure Therefore, in addition to the improved handling, the Heat loss between the two half shells reduced.

Figures 19 and 20 show an alternative embodiment of the second profile sections, this one Plastic part, in which an insert 40 from a heat-resistant material is embedded. This can be done as in Example of FIG. 19 is a metal profile shown is encapsulated with plastic or a Metal casting or ceramic part as shown in Fig. 20 is shown. The metal or ceramic part is preferably molded with the plastic that the material forms for the first profile sections. This owns the Advantage that the first and second profile sections can be welded or glued together. In in this case the connection could even be via tapes or There are no rags. In the same way you can also use rags be injected with, as in Fig. 19 by the broken lines is indicated.

Another advantage of designing the second Profile sections according to the embodiment of FIGS. 19 and 20 is that the outer contour of the second Profile sections of the outer contour of the first profile sections in the area of the receiving sections. By the Injection molding of the heat-resistant profile inserts can second profile sections with the receiving sections of the connecting profiles come into direct contact without it leads to an increased, undesirable heat flow. Indeed it is not mandatory in this embodiment that the second profile sections not less Can have outer contour in order to connect the allow first and second profile sections tolerances.

The production of the thermal insulation profiles according to the invention preferably takes place immediately after the extrusion the plastic insulation strip in line with the extrusion. By the provision of a suitable insertion aid into which the Profile sections are inserted and then either with the help of a tape or with the help of the described Connection tabs are connected.
