Description

Frame profile and method for assembling a flexible strip with at least one insulating structural material layer into a frame profile

Technical Field

The present invention relates to a frame profile according to the preamble of claim 1 and to a method for assembling a bendable strip with at least one layer of insulating construction material into a frame profile.

Background

The fire-resistant frame profile usually comprises a frame profile with a hollow space into which a fire-resistant plate in the form of a rigid plate, in particular a plasterboard or a profiled plate, is pushed. In this case, it is problematic in the assembly that, when using these fire protection plates, a pretreatment of the fire protection plate, for example a cutting or milling, must be carried out in the fitting chamber, in particular in the fitting chamber, whereby the fitting can be installed.

Furthermore, the use of bendable bands in frame profiles is known (see fig. 10). However, these flexible strips have the disadvantage that they cannot be pushed into the empty space of the frame profile because of the lack of dimensional stability. The band is therefore used during assembly in the area in which it can be inserted without problems.

Disclosure of Invention

The invention is based on the object of providing fire protection measures in the chambers of the frame profiles, in particular the fitting chambers, which are easy to assemble and, in addition, enable a simplified assembly of the fitting parts in the fitting chambers described above.

The invention solves this object by providing a frame profile having the features of claim 1 and by a method having the features of claim 15.

The frame profile according to the invention can be used in particular for fire-resistant frame structures. Typically, such fire rated frame structures have a jamb frame and/or a wing frame of a window, door or facade. In both frames, the frame profile according to the invention can be used.

The frame profile has a recess and two profile elements which bound the recess with respect to their width. The profile elements can be connected to one another by one or more insulating webs. The recess is in particular designed as a hollow space, so that the band cannot be inserted easily, but rather has to be pushed in.

The frame profile comprises a bendable strip arranged in the void. The strip can have at least one insulating structural material layer and in a preferred variant is made of an insulating structural material, in particular based on a textile reinforcement of calcium magnesium silicate.

The band has a width in the flat orientation that is greater than a width of the void. Thereby, a deformation of the band is forcibly generated, so that the band is clampingly disposed in the gap.

The belt is flexible, for example a textile belt, and can be moved within the hollow space when the fitting is assembled, so that the fitting can be assembled without problems.

Advantageous embodiments of the invention are the subject matter of the dependent claims.

Preferably, the recess is designed as a hollow space, in particular as a fitting space.

The tape is preferably designed as a fire-resistant insulating tape and is assigned to the structural material class B2. Under the action of heat, the belt tends to glaze.

The insulating structural material layer of the tape may advantageously have calcium silicate and/or magnesium silicate, preferably calcium magnesium silicate.

The band may be formed of an insulating structural material and configured to be bendable.

Furthermore, the belt may have a textile, preferably a textile reinforcement.

In a further preferred embodiment variant, the strip can have a support layer, preferably a lattice support layer, which is elastically deformable. In this variant, it is thereby advantageously possible to dispense with mounting aids, for example mounting rails, and the belt can be inserted without aids into the frame profile.

The strip may have a curvature, in particular a single curvature, in the recess.

Alternatively, the band may be folded in the gap. In particular, the strip can also be pleated.

The band can advantageously be arranged in the recess in a force-fitting manner, in particular in a clamping manner.

An additional anti-slip protection is achieved in that the profile element has a projection which projects into the recess and on which the band, in particular the end of the band, rests.

In addition, a particular advantage of the strip according to the invention is that, unlike rigid plates, it is not prone to rattling in the hollow space, so that additional fastening means, as are used in the case of rigid plates, for example plasterboard, can be dispensed with in the frame profile according to the invention.

Preferably, the strip may have a thickness of between 1-10mm, preferably 2-6 mm.

In the case where the strip is provided in the void, the strip preferably contacts two profile elements defining the width of the void or void.

In a manner known per se (see fig. 10), the frame profile can have an interface slot, in particular a glass interface slot, and a further strip with at least one layer of insulating structural material, which is arranged in the interface slot.

The method according to the invention for assembling a flexible strip having at least one insulating construction material layer into a frame profile for providing a frame profile according to the invention has the following steps:

i placing the band into an assembly track;

II, pushing the assembling track into the gap;

III temporarily or permanently fixing the tape in or near the void; and is

IV the assembly rail is guided out of the gap.

Detailed Description

Fig. 1 shows a fire protection profile system according to the invention, also referred to in the context of the invention as a fire protection frame structure, comprising frame profiles 1 and wing profiles 2 of window, door and/or facade elements, which are connected to each other by hinges 25. The profile system can particularly preferably be part of a fire door or part of a smoke door. Of course, the frame profile according to the invention, for example in the case of a facade element, can also relate to a frame profile installed in a facade element, comprising a facade panel which is fixedly enclosed in a frame.

The cheek frame profile 1 of fig. 1 has first and

second profile elements

5 and 6, preferably designed as metal profile elements. The two profile elements are preferably oriented parallel to one another. The two

profile elements

5 and 6 are preferably connected to one another by a first and a second

insulating web

3 and 4, for example plastic webs, wherein the two insulating webs are preferably oriented parallel to one another. Non-insulated profiles comprising connecting tabs made of the same material as the

profile elements

5 and 6 are also realizable within the scope of the invention.

In the case of the variant of fig. 1, the first profile element 5 is configured as the long side 9 of the cheek frame profile 1 and the second profile element 6 is configured as the short side 10 of the cheek frame profile 1.

The first profile element 5 also has a hollow space 11 into which a rigid plate, for example a fire protection plate 13, is arranged, in particular pushed. The second profile element 6 also has a hollow space 12, which comprises a rigid plate, in particular a fire protection plate 14, arranged therein. As fire protection plates, shaped element plates (formcell-plastern) or plasterboard known per se or, if appropriate, foam plates can be used within the scope of the invention.

The first profile element 5 embodied as a long side 9 can have a sealing device 15 at the end for bearing on the wing frame profile.

The first and

further profile elements

5 and 6 bound the recess 16, which is preferably designed as a hollow space, at its width B1. The recess 16 is also delimited by the two insulating

webs

3 and 4, so that a space is formed.

Parallel to the insulating

webs

3 and 4, a covering profile 7 also extends between the two

profile elements

5 and 6.

Starting from the

profile elements

5 and 6, in each case a

projection

18, 19, 20, 21 projects into the recess 16, which may be part of a groove for holding the insulating

webs

3 and 4 or the covering profile 7.

In the interspace 16 or in the hollow space, a strip 8 of insulating structural material is arranged. The strip has a width BB1 in the flat orientation that is greater than the width B1 of the void 16 defined by the

profile elements

5 and 6.

Since the strip 8 made of insulating structural material can of course be bent or formed flexibly, it can be deformed such that it produces a "U" or a "V" or an "S" which is turned over at 90 ° in cross section or the like. The strip 8 made of insulating structural material is bent or bent into the recess 16.

In fig. 1, the belt 8 is additionally supported in cross section on its ends on the

projections

20 and 21 and, if appropriate, in the middle section on the

projections

18 and 19.

The belt can be arranged clamped in the recess 16 by a restoring or restoring force into a flat position or into a position with a greater width of the belt 8.

The wing profile 2 shown in fig. 1 also has a first and a

second profile element

30 and 31, in particular a metal profile element, wherein the two

profile elements

30 and 31 also run parallel to one another here and are connected to one another by an insulating web 34.

The first profile element 30 is in this case designed as the long side 32 of the wing profile 2 and the second profile element 31 is designed as the short side 33 of the wing profile 2, wherein the sealing device 15 of the first profile element 5 of the frame 1 designed as the long side 9 rests on the second profile element 31 of the wing frame 2 designed as the short side 33.

The first profile element 30 of the wing frame 2, which is embodied as the long side 32, also has a sealing device 42a at the end, which rests against the second profile element 6 of the frame 1, which is embodied as the short side 10.

The first and

second profile elements

30 and 31 also each have a

hollow space

36, 37, 51, 52, wherein a rigid plate, in particular a

fire protection plate

38, 39, 53, 54, can be arranged, in particular pushed, into the or each hollow space.

On the outer side a, the wing frame profile 2 can be covered by the cheek frame profile 1. On the side B of the frame profile 2 opposite the outer side a, it has an interface channel 40, for example a glass interface channel, which is formed by two

edge sections

43 and 44 and a sealing element arranged thereon.

In fig. 1, the interface slot 40 is configured as a glass interface slot and a fire-proof glass arrangement 41 is arranged in said interface slot.

In addition to the insulating web 34, the two

profile elements

30 and 31 are connected to one another by a covering profile 42.

The

profile elements

30 and 31, the insulating webs 34 and the covering profile 42 define a recess 46 configured as a hollow space. Proceeding from the

profile elements

30 and 31,

projections

47, 48, 49 and 50 project into the recess 46, which projections are designed as parts of a groove for receiving or fastening a sealing element, an insulating web and/or a covering web.

Here, the space 46 extends parallel to the cavity 16 of the cheek frame profile when the cheek frame profile 1 and the fan blade frame profile 2 are in contact and parallel to the edge of the glass unit 41 or the bottom of the interface slot 40.

In the recess 46, a strip 45 made of insulating structural material is arranged, in particular inserted and clamped, in a manner similar to the frame profile 1. In this embodiment variant too, the width BB1 of the strip 45 in the flat orientation is wider than the width B1 of the recess 46 defined by the first and

second profile elements

30, 31. Specifically, in this embodiment variant, the width BB1 of the belt 45 corresponds to the width BB1 of the belt 8 and the width B1 of the gap 16 corresponds to the width B1 of the gap 46. The

belts

8 and 45 have only one bend 17 in the variant of fig. 1. The ends of the strip 45 also lie distally against the

projections

47 and 48.

Fig. 2 shows another embodiment of a profile system 500 ' with a cheek frame profile 1 ', which cheek frame profile 1 ' is connected to a fan wing frame profile 2 ' by a hinge 25 '. In this embodiment variant, the distance of the profile elements of the respective frame profile 1 'or 2' and thus the width B2 of the recesses or chambers 16 'and 46' is smaller. At the same time, the width of the strips 8 ' and 45 ' is the same or greater relative to fig. 1, so that the strips form a more strongly curved portion 17 '.

Within the scope of the invention, a distinction is to be made between the width of the strip and the length of the strip. The length of the strip is understood to be the cut length, which is adapted specifically to the length of the respective profile. The tape may preferably be supplied as a roll of tape, wherein the length of the tape is produced by unwinding of the tape. In contrast, in the case of the leading use, the width is not cut or only partially cut, for example, so that the ends can be introduced better into the hollow space of the profile. To clarify this distinction, the length of the band is also defined in the scope of the invention as the cut length.

Fig. 3 shows a variant of the embodiment of fig. 1 and illustrates the actual use of the

recesses

16, 46 or chambers. The recess or void is typically used to receive an accessory element, such as a lock housing, a lock bar, or the like. The

recesses

16, 46, 16 'and 46' or the empty chambers are therefore also generally referred to as fitting chambers. The fitting chamber is often protected in the frame profile in order to ensure increased security against theft. In fig. 3, two

fitting elements

100 and 200 are shown within the fitting chamber described above.

The use of bendable tapes, in contrast to the hard and rigid panels that have been partially utilized in fire doors to date, is particularly: for assembling the fitting element, the strip can be pushed apart and thereby deformed.

The hardening, in particular the glazing, of the strip under the effect of heat occurs only in the event of a fire, so that the arrangement of the strip as a fire protection measure does not prevent the fitting of the fitting in the frame profile.

Fig. 4 to 9 show in a schematic manner the sequence of a plurality of method steps for assembling the

strips

8, 45, 8 'and 45' in the frame profile.

Fig. 4 shows the placement (step I) of a substantially flat strip 301 into an assembly track 302. The mounting rail has a U-shaped cross section in this embodiment variant, although other variants, for example a V-shaped cross section, are also possible within the scope of the invention.

Fig. 5 shows a preferred variant of the insertion by unwinding the tape of the tape roll 305. The arrows show on the one hand the deployment direction AR and the insertion direction E.

The insertion is carried out by bending the strip 301 towards the opening 303 of the mounting rail 302, wherein the edge 304 of the strip 301 is in or points towards the corner of the mounting rail 302.

Fig. 6 shows the assembly rail pushed (step II) into the

recess

8, 45, 8 'or 45' of the frame profile. The assembly rail 302 is smaller in size in the cross section of the rail than the corresponding recess 8, so that the assembly rail can be inserted into the frame profile.

Fig. 7 shows the fixing of the fabric strip. The fixing can be performed manually by an assembler or by means of a releasable or non-releasable connecting mechanism, such as a clip, rivet, screw or the like.

Fig. 8 shows the removal of the assembly rail from the frame profile by pulling out the assembly rail, wherein the belt is held in the frame profile, optionally by the user or after a certain pull-out travel of the assembly rail by the clamping or friction of the belt itself.

Fig. 9 shows a further embodiment variant of a belt 401 for use in the frame profile according to the invention. The strip has, in addition to a layer 402 of flexible insulating structural material, a flexible support layer 403 which is elastically deformable. This means that the support layer returns to its original shape after bending. A typical example of such a support layer is a rubber grid layer, preferably having a U-or V-shaped profile. The plastic can also be designed as a support layer in this design. A lattice-shaped design of the supporting layer is particularly suitable for the support.

The supporting layer 403 can be deformed during the insertion and can be clamped in the frame profile by a restoring force associated with the material. In this variant, the use of mounting rails can advantageously be dispensed with, since the supporting layer can exert sufficient dimensional stability for the introduction of the insulating structural material layer.

The

strip

8, 45, 8 ', 45', 301, 401 made of insulating structural material can be configured as a fire-resistant insulating strip. Particularly preferably, it is a fire protection insulation tape for use in fires with structural material class B2 according to DIN 4102-1 (normally flammable) and class E according to DIN EN 13501-1 (respectively cited standards of the text of the current version at the time of priority of the invention).

The strip preferably has calcium magnesium silicate as material, in particular as a fire-resistant insulation layer. It is particularly preferred that the belt is a woven material which is provided with the above-mentioned silicate by coating, impregnation or the like.

At least the insulating layer of the tape or the tape as a whole has a preferred tape thickness of between 1 and 10mm, preferably between 2 and 6mm

Or tape thickness (Banddicke).

Typical widths of the strip are at least 5mm, preferably between 8 and 200mm, particularly preferably between 80 and 120 mm.

For the simplest possible assembly according to the method described above, the tape is non-self-adhesive.

The belt may preferably have 200 to 300kg/m under standard conditions³(iii) bulk density of (Rohdichte).

Further, the tape may have a heat resistance of at least 1000 ℃, preferably 1150 to 1300 ℃, and have a melting point of more than 1300 ℃. The tensile strength may be greater than 0.35N/mm²。

Further, the tape may have a thermal conductivity of 0.10 at 400 ℃. Particularly preferably, the tape can also be used as a guide strip (Vorlegeband).

Particularly preferably, a tape (composition at the time of the priority date of the present invention) of Kuhn company having the product name "Kerafix 2000" can be used as the tape of the present invention for the above purpose.

The product "Kerafix 2000" has been used in this connection as a fire protection mechanism in frame profiles. Figure 10 shows a known per se use of a belt. In the current assembly of the frame profile, a first profile element T1, a first strip T2, a glass element T3, a second strip T4 and a further profile element T5 are inserted in succession and connected to form the frame profile.

However, due to its flexible design, the use of the band in empty chambers has not been considered so far, since the band cannot be pushed in easily. The present invention and in particular the method for assembling the belt according to the invention now provides a feasible solution. At the same time, the empty chamber, which is typically formed as a fitting chamber, is provided with a fire protection element without making it difficult to over-assemble the fitting.

Fig. 11 to 13 show a further embodiment variant of a belt 501 for use in the frame profile according to the invention. The tape has, similar to fig. 9, a layer of insulating structural material 502 and a bendable support layer 503, which is elastically deformable. This means that the support layer strives to return into its original shape after bending. Thereby, the supporting layer is at least partially deformed back. The same applies, in particular to a reduced extent, to the layer of flexible insulating structural material and also to the joining of the two layers. Typical examples of such support layers 503 have a U-or V-shaped profile.

Similarly to fig. 9, the insulating structural material layer 502 in fig. 12 and 12a has a supporting layer 503 at least on one side, which is however slotted from two positions, i.e. has two

longitudinal slots

507 and 508 running parallel in the longitudinal direction of the strip 501, so that the insulating structural material layer 502 can be bent, while the supporting layer 503 is interrupted by the two

slots

507 and 508 over the total width b1 of the strip 501. This enables a better deformability of the strip 501, so that it can be rolled up on the one hand into a roll 600 as shown in fig. 11 and on the other hand, after unrolling, is applied autonomously over a large area within the profile over at least 50%, preferably at least 80%, particularly preferably more than 90%, of its respective total width to the

profile elements

515 and 516 of the profile 511 and also to the connecting webs 517 of the connecting profile elements, due to the restoring or erecting force of the insulating structural material layer.

However, the support layer 503 may also be arranged completely outside around the insulating structural material layer 502.

The use of the strip 501 in the profile 511 can be seen in fig. 13.

The slot depth of the

longitudinal slots

507 and 508 may be determined at least such that the support layer is cut along the slots. In particular, the slot depth may be at least 20%, preferably 30-80%, of the thickness of the strip 501. Preferably, the slot depth t can be at least 0.5, particularly preferably between 1 and 3 mm.

The support layer 503 may be formed of a plastic film sheet. Particularly preferably, the membrane can be formed from a thermoplastic, preferably a polyether and particularly preferably polyethylene terephthalate.

The support layer 503 is connected, in particular materially, preferably by lamination, to the insulating structural material layer 502.

The thickness of the support layer 503 is less than 15%, preferably less than 10%, particularly preferably less than 5% of the insulating structural material layer 502.

The

longitudinal slots

507 and 508 divide the strip 501 along its total width b1 into a middle section 509 and two wing sections 510 extending parallel to each other. The added width b2 of the two wing segments 510 is smaller than the width b3 of the middle segment, so that the two wing segments 510 can be arranged on the middle segment folded over and alongside one another. Between the wing segments 510, intermediate spaces 520 can be provided, which are dimensioned according to the dimensioning of the recess 518 of the profile 501, which is delimited by the

profile elements

515, 516 and the connecting webs 517.

Reference is made to fig. 14 as an example of another embodiment variant according to the invention comprising a belt 700 with a differently dimensioned intermediate gap 720 with respect to fig. 11 to 13.

The width b3 of the middle section and thus the width of the strip in the folded state of the wing sections is also smaller than the profile distance of the

profile elements

515 and 516. The variant of the strip of fig. 11 to 13 with respect to fig. 1 to 8 enables a wider contact area with the profile elements and easier introduction into the interspace 518. The strap 501 self-erects in the folded state, for example within the void 518.

The rise time of the wing segments 510 is gradual and here is more than 1 second, preferably more than 5 seconds but less than 5 minutes.

In the assembly method according to the invention as well, the strip 501 can be unwound from the strip coil 600 and, in the folded state of the wing segments 510, is arranged in the recess 518 of the profile 511. Due to the exposure of the intermediate space 520 in connection with the unfolding and/or setting, a separate erection of the segments in the linearly extending recesses 518 takes place until the segments 518 bear against the

profile elements

515 and 516.

The frame profile 501 may for example be used in a fire-proof frame structure with fire resistance of 60 minutes and/or 90 minutes.
