Description

The present invention relates to a frame and / or casement for a fire protection window, a fire protection door and / or a fire protection facade and a fire protection window, a fire protection door and / or a fire protection facade and a method for assembly. With the fire protection structures according to the invention, the fire protection classes are preferably according to DIN 4102 , the European standard EN 1364/1634 and / or a comparable standard for 30, 60 and especially 90 minutes. The aforementioned standards relate to their currently valid version on the filing date of the first filing of the present invention.

It's from the DE 44 43 762 A1 a frame construction for a window, a door and / or a facade in fire protection design is known, which has a cavity for receiving an insulator, for example a plasterboard. This document shows an arrangement of insulators in the hollow chambers of the aluminum profiles. So that the insulators can be positioned and, for example, do not rattle when the elements are operated, they are secured with holders. These holders press the insulators against a wall of the hollow chamber.

The insulators usually lie against the outer wall in order to be able to develop their cooling effect in the best possible way. However, if the limits of the dimensional stability of the aluminum walls are reached, e.g. if the aluminum melts in the event of a fire, the insulators are pushed out of the construction. From now on they offer no support, no statics and no cooling for the construction and even fall out of the construction completely, which means the end of the fire resistance.

Based on the prior art described above, the object of the present invention is to provide a blind and / or casement frame for a window, a door and / or a facade in the form of a fire protection construction, which in the event of a fire increases the service life of the fire resistance of the profile, by holding at least one insulator in a defined position for as long as possible in the event of a fire in order to support and cool the profile.

The present invention solves the problem by means of a blind and / or casement frame with the features of claim 1.

The areas of application are, for example, fire protection windows, fire protection doors and / or fire protection facades including roof structures. These have plate-shaped components. The plate-shaped components are not part of the blind and / or casement frame according to the invention, but are enclosed by this.

A frame and / or casement according to the invention for a window, a door and / or a facade corresponds to the design as a fire protection construction according to DIN 4102-2 and is suitable for framing a panel-shaped component, e.g. a window pane.

The frame and / or sash comprises a first profile element and at least one hollow chamber with a hollow space which extends parallel to the profile element, with at least one first insulator being arranged in the hollow chamber.

The hollow chamber can be arranged in the profile element. In this case one can speak of a hollow chamber profile. The hollow chamber can alternatively or additionally be arranged between two profile elements.

A profile element can in particular be a cut-to-length hollow chamber profile, which is preferably made of metal, in particular steel or aluminum, for fire protection. However, there are also hollow-chamber plastic profiles which meet fire protection requirements and which can be used within the scope of the present invention.

Hollow chamber can have at least one first wall which runs parallel to the visible surface of the plate-shaped component enclosed by the frame and / or casement.

Furthermore, the hollow chamber can have at least one second wall which is inclined or perpendicular to the first wall and which delimits the hollow space of the hollow chamber together with the first wall. The second wall will be perpendicular to the first wall in the majority of applications. However, there are also some applications in which the second wall can deviate from the perpendicular orientation by a small angle, preferably by less than 20 °, particularly preferably by less than 10 °.

A first clamping spring can be arranged in the hollow chamber and clamp the first insulator in the hollow clamp

According to the invention, the clamping spring is arranged in the hollow chamber in such a way that the clamping spring is supported against the second wall of the hollow chamber and presses the insulator away from this second wall.

Since the second wall is inclined or perpendicular to the said visible surface, the insulator becomes In the event of a fire, it is no longer pushed out of the profile, but against the wall or away from the wall against the enclosed component. The insulator therefore also contributes to the stability and cooling of the remaining construction when individual walls of the profile element are melted.

Advantageous refinements of the invention are the subject matter of the subclaims.

The frame and / or casement for enclosing the plate-shaped component is typically formed from a plurality of profiles, the profile element being at least part of one of these profiles, in particular each of these profiles, and the hollow chamber being arranged in the profile element. A profile can also be formed from just one profile element or from several profile elements that are connected to one another, e.g. via insulating bars.

The frame and / or casement can preferably also be formed from a plurality of profiles, the profile being formed by two profile elements which are connected to one another by insulating webs. A hollow chamber in the profile can also be arranged between a first and a second profile element.

The clamping spring can thus, based on the two aforementioned design variants, be arranged in a cavity in the profile element or in a cavity between two profile elements and at this point clamp the insulator in the respective cavity.

The variant of jamming an insulator in a cavity between two profile elements is useful, for example, in constructions in which the profile elements are not designed as hollow chamber profiles, but merely as plate-shaped cover profiles.

It is also advantageous if the hollow chamber has a third wall which delimits the hollow space together with the first wall and the second wall, the third wall being arranged on an opposite side to the second wall and the insulator against the third by the clamping spring Wall is pressed.

It is advantageous if the second wall is part of a storage side of the blind and / or casement frame for the storage of the plate-shaped component. Even if the frame material, e.g. the window or door sash, melts, the insulator still provides a certain level of stability when holding the component in the masonry, since the clamping spring and the insulator hold the component in the masonry or in a frame attached to the masonry or anchor another outer frame.

For an optimal pressure distribution over a wide edge area, it is advantageous if the clamping spring is designed as a flat spring. The flat spring can advantageously be designed as a curved, strip-shaped element with a convex and a concave flat side for an optimized force transmission.

The clamping spring for developing a restoring or clamping force is particularly preferably made from metal, in particular from a spring steel.

For the most energy-saving deformation possible with a simultaneous build-up of a restoring force, the clamping spring has a material thickness of less than 1.5 mm, preferably between 0.2-0.8 mm.

The clamping spring can have a projection for better fixation in the cavity, the projection protruding obliquely, preferably perpendicularly, from a flat side, in particular the convex flat side.

The projection can protrude from the flat side of the clamping spring by at least 5 times, preferably 10-100 times the material thickness.

For a force distribution, it is advantageous if the clamping spring, the clamping spring, has a length of at least 20 mm-150 mm, in particular 30 mm-130 mm. For a broad application of force, it is also advantageous that the clamping spring has a width of at least 20 mm-30 mm, preferably 15 mm-25 mm.

For better fixation against lateral displacement in the cavity, the clamping spring can have at least two tapering end regions in the longitudinal direction at a first end.

However, in order to achieve optimal deformation, it is advantageous if the clamping spring has a straight edge at a second end so that the clamping spring can perform an evasive movement on one side

For additional anchoring in the insulating material of the insulator, the clamping spring can each have a bevel at the tapering end regions for engaging or piercing into the insulator material.

The clamping spring is advantageously bent downwards in the longitudinal direction, the bend on both sides of the spring being at least 15 ° -45 °, particularly preferably 20 ° -40 °.

The bending radius can advantageously be 50-90 mm, particularly preferably at least 60-80 mm.

The projection can be arranged centrally in the longitudinal direction of the clamping spring, so that a force transmission acts centrally on the spring when force is applied to the projection.

The projection can be formed by bending a portion which is delimited by two incisions, each incision being between 20-60% of the width of the clamping spring. As a result, the projection is formed to a sufficient extent, while at the same time the stability of the clamping spring is maintained despite the weakening of the material in the central area.

The second wall of the hollow chamber can have a groove for receiving the projection of the clamping spring. This prevents the clamping spring from being displaced perpendicular to the direction of force or clamping. Alternatively, instead of the groove, only a projection can be provided which forms a stop for the projection of the clamping spring.

The projection can be arranged with play in the groove, the lateral groove walls of the groove being designed as stops for the projection. The play facilitates the insertion of the insulator, with the interaction of the projection and the groove resulting in a certain guidance during the insertion during assembly.

Advantageously for optimal fastening, a second clamping spring, which is identical to the first clamping spring, can be arranged at a distance of at least 0.4 m from the first clamping spring between the insulator and the second wall. The clamping springs are arranged on the same insulator, only offset from one another in the longitudinal direction of the insulator.

A fire protection window, fire door and / or fire protection facade according to the invention comprises a blind and / or casement frame according to the invention and the plate-shaped component which is enclosed by the blind and / or casement, the component preferably being a pane or a front panel, in particular a glass pane, plastic panel , Composite panel and / or decorative panels. In the context of the present invention, a window sash or door sash can also be understood as a fire protection window or fire protection door, which is movable with respect to a frame and / or sash fixed in a masonry or a frame fixed in a masonry. In this case, the fixed frame can preferably also belong to the blind and / or casement frame according to the invention.

1 shows a schematic view of a window 1 . A window within the meaning of the present invention can be used as a casement 2 " or as a combination of a casement 2 " in a frame 2 " be understood. It is therefore also possible that a window frame in a frame in the form of a frame or an outer frame or the like, for example anchored in masonry, to hold the window sash 1 , can be provided. The same applies to door leaves or facade elements.

The window has a sash 2 " for holding a plate-shaped component 3 , also called filling. Said component can be designed, inter alia, as a glass pane, plastic panel, composite panel, decorative panels or the like. This plate-shaped component 3 is of the sash according to the invention 2 " edged. A common case is the framing of a window pane with such a frame.

The casement according to the invention 2 " the 1 sits in 1 from four profiles 4th together, but there are also other less common window constructions, for example in triangular shape, with round arches, hexagonal shapes, etc., in which fewer or more than four profiles are required for the construction of a blind and / or casement frame.

A corner connection made of two identically structured profiles 4th and 4a a frame and / or sash according to the invention is in 2 and 3 shown.

The profile 4th the 2 and 3 is made up of two profile elements 5 and 6th formed, each of which has a hollow chamber 19th feature. The respective hollow chamber 19th has one in the longitudinal direction L. of the respective profile element 5 or 6th extending cavity on which at least three sides of walls 15th , 16 , 17th is limited. Of course you can in the walls 15-17 , for example due to assembly, bores and recesses may be provided. The frame and / or casement has two visible surfaces 13th and 14th which are visually perceived by the viewer of the window. The plate-shaped component also points parallel to the visible surfaces 13th and 14th a visible surface, i.e. the surface of the glass pane.

The walls are arranged in such a way that a first wall 15th is arranged parallel to a visible surface of the plate-shaped component. A second wall is inclined or perpendicular to it 16 arranged. In this context, oblique means any deviation of 90 ° and 180 ° from the wall and particularly preferably includes angles between 70-110 ° to the first wall 15th .

The profile elements 5 and 6th can preferably consist of a uniform material, for example and in terms of fire protection preferably made of metal, in particular steel or aluminum. The insulating bars 8th can consist of a plastic material. The insulating bars 8th engage in the grooves of the two profile elements 5 and 6th and form together with the two profile elements 5 and 6th another hollow chamber 7th the end.

The profile 4th has, in a manner known per se, a storage side which serves as a storage area for the said plate-shaped component 3 is provided. In 3 and 4th the shelf side becomes through the insulating bars 8th and formed by protrusions of the wall 16 for the formation of grooves 12th . The grooves 12th are intended to accommodate retaining strips for the filling of the frame, for example glass panes.

The hollow chambers provide thermal insulation and improve service life in the event of fire 19th a first insulator each 9 on. This can, for example, be made of a plaster of paris material, wollastonite, calcium silicate or the like, or it can be designed as a mineral plate. The isolator 9 is in the hollow chamber 19th inserted, with the insulator 9 for insertion with play in the hollow chamber 19th is present. To fix the isolator in the frame and / or casement 2 becomes a clamping spring 18th between the second wall 16 the hollow chamber 19th and the first isolator 9 used.

The clamping spring 18th is designed in particular as a flat spring and is supported against the second wall 16 and presses the insulator 9 outwards against the third wall 17th . However, the clamping spring is also possible within the scope of the present invention 18th such between the insulator 9 and the third wall 17th to order that the insulator 9 to the inside or to the shelf side 11 towards the second wall 16 is pressed.

In contrast to the prior art, there is therefore no pressure through the isolator 9 against the visible side 14th having first wall 15th which, in the event of a fire, is subject to the greatest heat and is the first to be subject to destabilization and deformation. This would be additionally unfavorably increased by the pressure of the insulator on this wall.

The present invention thus makes it possible by clever positioning of the clamping spring 18th the unwanted rattle of the isolator 9 when moving the frame 2 , 2 ' , 2 " to prevent and at the same time to achieve an increased service life compared to the solutions in the prior art.

The clamping spring 18th is in 2 and 3 recognizable as a flat spring. It can be made of metal, in particular a spring steel. In the relaxed state, it is designed as an arc-shaped strip and each has two flat sides 24 and 25th , as well as two edge sides 26th and 27 and two ends 23 and 29 on.

It is used when assembling the profile 4th before assembling the profiles 4th , 4a to a blind and / or casement frame 2 while inserting the isolator 9 in the profile 4th on the isolator 9 placed, depressed with the formation of restoring forces and with the insulator 9 inserted.

The clamping spring 18th has two pointed end regions at one end 23 on. These also have bevels at the end 30th so that they get caught in the insulator material when the clamping spring is pressed and the clamping spring slips 18th on the insulator material of the insulator 9 additionally prevent.

At the second end 29 can the clamping spring 18th have a continuous edge, which may be slidable on the insulator 9 is.

The clamping spring has in a middle segment 18th a head start 21 on which one from the curved flat side 24 the clamping spring 18th protrudes. The lead 21 is through from the longitudinal edge into one edge side 26th made two incisions 28 and a subsequent bending out of the plane of the flat side.

Accordingly, there is a bending point of the clamping spring 18th at the transition of the projection 21 in the first flat side 24 the clamping spring.

The clamping spring 18th is detailed in the 7-10 shown and described below in a preferred embodiment with regard to their dimensions and design.

The clamping spring has a material thickness d of less than 1.5 mm, preferably between 0.2-0.8 mm.

The lead 21 and the fold 30th define together with the bend of the clamping spring 18th a total height v . This can preferably be between 13.0 mm and 15.5 mm.

The height H which solely by the bending of the clamping spring 18th is formed is preferably between 75% and 85% of the total overall height v .

The height s of the folds 30th is preferably at least twice the material thickness d .

The preferred length I. the clamping spring 18th can be between 20 mm - 150 mm, in particular 30 mm - 130 mm, in particular 80 - 120 mm.

The clamping spring one width b of at least 15 mm - 30 mm, preferably 20 mm - 25 mm.

The length I. the clamping spring is divided into at least two partial lengths l1 and l2 between which the projection 18th is arranged.

The tapered end sections 23 have a maximum distance at the top t on, which can preferably be between 8-12 mm.

4-6 shows different profiles 4th , 4 ' , 4 " with different profile heights with a uniform profile width. The dimensioning of the profile elements varies with the profile height 5 and 6th and the isolators 9 and 10 .

6a shows a groove in detail 20th in which the projection 21 the clamping spring is placed. In this case, the side surfaces of the groove serve as stop surfaces and, apart from a certain amount of play, prevent lateral displacement of the clamping spring.

Instead of a groove, only a projection can be provided which prevents a lateral displacement in a lateral direction.

1-10 shows preferred design variants of a profile 4th , 4 ' , 4 " as a composite profile with clamping springs 18th which are the isolators 9 in the Cavities 19th of the profile elements 5 and 6th jam. The profile elements 5 and 6th are designed as hollow profiles and are also referred to below as external profiles.

The isolator 10 in hollow chamber 7th can alternatively or additionally also be fixed clamped with a clamping spring. The clamping spring is supported against a first of the insulating bars 8th which in this case represents the second wall, and is pressed against the second, opposite insulating bar. In this way, additional stabilization can be achieved in the event of fire protection.

Overall, the design of the aforementioned frame and / or casement can increase the service life of the construction. In particular, the outer chamber insulators, i.e. the insulators 9 in the hollow chambers 19th of the profile elements 5 and 6th , should remain in the hollow chamber for as long as possible in the event of fire 19th remain to a respective profile 4th which is in 3 and 4th is designed as a composite profile to protect and cool for as long as possible. For this purpose, the insulators are held according to the invention by the optimal positioning of the clamping springs in the cavity.

In contrast to previous solutions, in which springs are only used as "rattle protection", the aforementioned positioning of the clamping spring has an additional primary function. In interaction with the applied tension and the upwardly curved projection 21 becomes the isolator 9 Protected against falling out in the event of fire or the falling out of the isolators 9 is significantly delayed as a result.

The assembly of the frame and / or casement is surprisingly simple as such, but with outstanding properties.
