EP2990581B1 - Door or window with fire protection properties - Google Patents

Description

The present invention relates to a door or window with fire protection properties according to the preamble of claim 1.

Such doors or windows with fire protection properties are known from the prior art.

the DE 85 05 873 discloses a prior art door or window.

Composite profiles consist of at least one metallic outer profile and one metallic inner profile, which are connected to one another by at least one element that reduces the passage of heat, for example an insulating bar. The disadvantage of such composite profiles is that they bend at different temperatures on the inside and outside of a component made from them, for example a door. This phenomenon is usually referred to as the so-called bimetallic effect.

This bimetallic effect can easily lead to leaks, which must be avoided at all costs, especially in fire protection constructions. Numerous solutions have already been proposed to eliminate the problem of the bimetallic effect. A solution that has proven particularly useful is in the EP 0 829 609 B1 described.

Fire protection constructions made from thermally separated profile constructions have also been known for a long time. For example, in the EP 0 717 165 B1 describes a profile system in fire protection design, which consists of a metal profile that has a central area in which the heat flow is reduced compared to the outer areas. The disadvantage of such fire protection constructions is that they also bend in the event of a fire, ie at different temperatures on the inside and outside. Here, too, the so-called bimetallic effect occurs as a result of the temperature development in the event of a fire. Due to the bimetallic effect, fire protection constructions can even cause flames to propagate through a corresponding component, such as a door. To remedy this, the sash frames are locked several times to prevent sagging. In addition, in the chambers between the Elements (window frame/casement) fire protection materials are used, which react or foam up with an endothermic reaction when exposed to the appropriate temperature and thus prevent hot gases or flames from penetrating through the chambers.

Both the use of special insulation profiles made of fire protection materials and the use of multiple locking mechanisms are complex and therefore expensive and also prone to repairs.

Based on this state of the art, the invention therefore has the task of creating a door or a window with fire protection properties which at least significantly reduces the disadvantages mentioned above, in particular the bimetallic effect of the profiles, both under ambient temperatures and in the event of a fire. Fire protection means at least observing a fire protection of 30 minutes (T 30).

The present invention solves this problem by the subject matter of claim 1.

Accordingly, it is provided according to the invention that at least one of the vertical wing frame struts is made from a profile that is not thermally separated. A profile that is not thermally separated is preferably a profile made of metal or a metal alloy in which two or more metal profiles or shells are not separated by one or more insulating bars or in which one or more insulating profiles do not separate the metal profiles of a composite profile from one another separate.

The invention deliberately dispenses with the advantages of thermal separation in the casement in order to obtain the greater advantages of a construction according to the invention for doors or windows with fire protection properties—namely the avoidance of the bimetallic effect in the event of a fire. Doors or windows with fire protection properties are understood to be those that comply with at least the T-30 standard (fire protection or fire protection class) or more.

By designing a door or a window with fire protection properties according to the invention with a sash frame without or with only partial thermal separation and a window frame with thermal separation, it is possible in a particularly simple and therefore advantageous manner to use locking devices that are expensive and complex to install and/or special insulating profiles Fire protection properties are dispensed with.

The construction described, which is to be used for fire protection doors or windows, is thus advantageously characterized by a considerable cost advantage compared to the prior art, since expensive multiple locks and a correspondingly complex installation can be dispensed with.

Further advantageous embodiments of the invention can be found in the dependent claims.

Exemplary embodiments of the subject invention are shown in the drawings and are described in more detail below. It shows:

Figure 1:

Figure 2:

A sectional side view of the door 1 ;

Figure 3:

Figure 12 shows a sectional side view of a variant embodiment of the door 1 .

the 1 shows a door 1a, 1b with fire protection properties, which has a leaf frame 2 and a frame 3a, 3b. This is to be understood purely as an example. As an alternative to the in 1 shown door 1a, 1b, the present invention can also be used for windows or other structural elements.

For the present invention, the structure of the movable casement 2 is of particular importance. The sash 2 has a vertical sash spar 6 on the handle side and another vertical sash spar 7 on the hinge side. In addition, the casement 2 has an upper horizontal Casement spar 8 and a lower horizontal sash spar 9 on. The lower horizontal wing frame spar 9 can consist of a sogn. Be made base profile, but it can also be the same profile as the other sash frame spars 6, 7, 8 are used. The sash spars 6, 7, 8 are assembled into the sash 2, so that in the sash 2 a sogn. Filling 20 can be used. The frame 3a, 3b of this door 1 is equipped with side parts 10, 11 and has frame members 12a, 12b, 13a, 13b, 14a, 14b.

According to the invention, at least the vertical wing frame spar 6 is formed on the handle side from a profile 4 that is not thermally separated. Preferably, the second vertical sash frame spar 7 on the hinge side is also formed from the thermally unbroken profile 4, particularly preferably the upper horizontal sash frame spar 8 and very particularly preferably all four sash frame spars 6, 7, 8, 9 are made from the thermally unbroken profile 4. Such a design of the wing frame struts 6, 7, 8, 9 excludes a bimetallic effect in the wing frame when temperature is applied on one side or is only marginally pronounced.

In 2 the door is off 1 shown in section. For the sake of simplicity, only one horizontal section is shown. The horizontally extending sash spar 8 of the sash 2 is made of a thermally unseparated profile 4 here.

The thermally unbroken profile 4 has a T-shaped cross-section, with the "T" rotated 90° to the left. The profile has a central hollow chamber 15 . The thermally unseparated profile 4 also has two webs 16, 17, the free ends of which each have a groove 18, 19, each of which receives a sealing profile (not shown here). The thermally unseparated profile 4 also has a fold 23 into which the filling 20 is inserted. The fold 23 has a groove 21 into which a holding strip 22 is inserted. The thermally unseparated profile 4 is preferably made from a metal, particularly preferably from an aluminum material, using an extrusion process.

It is particularly advantageous that the profile contour of a thermally unseparated casement profile 4 corresponds to the contour of a thermally separated casement profile (not shown here), especially if these are connected to one another via mitred corners, e.g. B. if not all four sash spars 6, 7, 8, 9 are thermally unseparated.

The horizontal frame member 14a of the frame 3a is made of a composite profile 5a here.

The composite profile 5a has a first partial profile 24a, in which at least one hollow chamber 26a is formed here, and a second partial profile 25a, in which at least one hollow chamber 27a is also preferably formed. Alternatively, the metallic profiles 24a, 25a can also be designed without pronounced hollow chambers 26a, 27a, or can have several hollow chambers.

The first partial profile 24a is connected to the second partial profile 25a via at least one or more insulating strips 28a (aligned in parallel here). These insulating strips 28a between the first partial profile 24a and the second partial profile 25a form a first insulating strip zone I or plane.

The insulating bars 28a do not have a hollow chamber here—purely as an example. Alternatively, the insulating bars 28a can also have one or more hollow chambers, or the insulating bars 28a can be combined by transverse bars to form a type of superordinate insulating profile.

The insulating bars 28a of the insulating bar zone I are here - purely as an example - in one plane. Alternatively, it is also possible for the insulating strips 28a of the insulating strip zone I to be offset vertically and/or horizontally with respect to one another.

The first and second partial profiles 24a, 25a are preferably produced as extruded aluminum profiles. Alternatively, production from a different material such as steel and/or a different manufacturing process is also possible. The insulating webs 28a are made of a plastic material, so that a substantial thermal separation is achieved between the partial profiles 24a, 25a.

The insulating webs 28a are preferably web-shaped in cross section and have thickened end sections 29 . Each of the end sections 29 preferably engages in a corresponding groove 30 of one of the partial profiles 24a, 25a, with the groove walls enclosing the thickened end sections 29 of the insulating strips 28a in the x and y directions (see the coordinate system in 2 ) preferably embrace form-fitting. The respective end section 29 preferably has a trapezoidal or triangular or wedge-shaped or L-shaped or rectangular cross-section. The respective groove 30 accordingly has a cross section with a corresponding cross section in each case.

In order to obtain a shear-resistant and thus additionally non-positive connection between the respective end section 29 and the respective groove 30, it is advantageous if the respective end sections 29 are fixed in the respective groove 30 by a forming process and/or with a wire (not shown here ) are fixed, which has an outer structure, such as knurling, which increases the shear strength in the profile direction (perpendicular to the plane of the drawing 2 ) elevated. Alternatively, however, the end sections can also be inserted into the groove 30 using a suitable joining method without wire or the like.

The first partial profile 24a is preferably separated from the second partial profile 25a by a hollow chamber 31 which is formed in the first insulating strip zone I between the two insulating strips 28a and the adjoining metal profiles 24a, 25a. As a result, a number of hollow chambers 26a, 31 and 27a are formed from an outside of the first partial profile 24a to a second outside of the second metallic outer profile 25a, which ensure good thermal insulation. The second partial profile 25a has a web 32a, with a groove 33a for receiving a seal (not shown here) being provided at the end on the web 32a.

The invention is based on 2 The variant shown is not limited, but can also be implemented on a composite profile 5b, in which two partial profiles 24b, 25b (inner profile and outer profile) and a metallic central profile 35 (not shown here) are connected to one or more insulating bars 28b via two insulating bar zones I, II.

In 3 a variant of the door 1 is shown. The horizontal frame member 14b of the frame 3b is made of a composite profile 5b here.

In order to avoid repetition, only deviations or changes and additions to the embodiment variant of a composite profile 5a according to the invention described above are shown below 2 described.

The composite profile 5b has a first partial profile 24b, in which at least one hollow chamber 26b is formed here, and a second partial profile 25b, in which likewise preferably at least one hollow chamber 27b is formed. In addition, the composite profile 5b has a metallic central profile 35 in which at least one hollow chamber 36 is also preferably formed. Alternatively, the metallic profiles 24b, 25b, 35 can also be designed without pronounced hollow chambers 26b, 27b, 36 or have several hollow chambers.

The first partial profile 24b is connected to the central profile 35 via at least one or more insulating strips 28b (aligned in parallel here and arranged slightly offset horizontally). These insulating strips 28b between the first partial profile 24b and the middle profile 35 form a first insulating strip zone I or plane.

The central profile 35 is connected to the second partial profile 24b via at least one or more insulating strips 28b (aligned in parallel here and arranged slightly offset horizontally). These insulating strips 28b between the first partial profile 24b and the middle profile 35 form a second insulating strip zone II or level.

The first and second partial profile 24b, 25b and the middle profile 35 are preferably produced as extruded aluminum profiles. Alternatively, production from a different material such as steel and/or a different manufacturing process is also possible. The insulating webs 28b are made of a plastic material, so that in each case a substantial thermal separation between the partial profiles 24b, 25b and the central profile 35 is achieved.

The first partial profile 24b is preferably separated from the central profile 35 by a hollow chamber 37 which is formed in the first insulating strip zone I between the two insulating strips 28b and the adjoining metal profiles 24b, 35. The second partial profile 25b is preferably separated from the central profile 35 by a hollow chamber 38 which is formed in the first insulating strip zone II between the two insulating strips 28b and the adjoining metal profiles 25b, 35.

As a result, a number of hollow chambers 26b, 37, 36, 38 and 27b are formed from an outside of the first partial profile 24b to a second outside of the second partial profile 25b, which ensure good thermal insulation. The second partial profile 25b has a web 32b, with a groove 33b for receiving a seal (not shown here) being provided at the end on the web 32b.

The thermally non-separated profile 4 of the leaf frame 2 and the composite profile 5a, 5b of the frame 3a, 3b form a rebate area 34a, 34b when the door 1 is closed. The fold area 34a, 34b is sealed off from the environment by the seals (not shown here) for which the grooves 18 or 33a, 33b are provided.

According to the invention, the window frame 3a, 3b is thermally separated from the casement frame 2, so that temperatures above 140° do not occur on the side of the door 1a, 1b facing away from the fire.

The construction described, which should preferably be used for fire protection doors, is characterized in an advantageous manner by a considerable cost advantage, since expensive multiple locks and a correspondingly complex installation can be dispensed with. The majority of these doors (approx. 90%) are installed inside buildings anyway, so that the disadvantages of a thermally non-separated construction, as they occur when such doors are arranged in the building shell, hardly or not at all come into play.
