Description

The present invention relates to a door or a 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.

Composite profiles consist of at least one metallic outer profile and a metallic inner profile, which are connected to one another by at least one heat transfer reducing element, for example an insulating web. A disadvantage of such composite profiles is that they bend at different temperatures on the inside and outside of a built-up of them component, such as a door. This phenomenon is commonly referred to as a so-called bimetallic effect.

This bimetallic effect can easily lead to leaks that must be avoided especially in fire protection structures. To overcome the problem of the bimetallic effect, numerous solutions have already been proposed. A solution that has proven particularly useful in the EP 0 829 609 B1 described.

Fire protection structures made of thermally separated profile constructions have also been known for a long time. For example, in the EP 0 717 165 B1 a profile system described in fire protection, which consists of a metal profile having a central region in which the heat flow is reduced compared to the outer areas. A disadvantage of such fire protection structures is that these in case of fire, so at different temperatures on the inside and outside), also bend. Here too, the cause of the temperature development in the event of fire is the so-called bimetallic effect. Due to the bimetallic effect, fire protection constructions can even result in flame penetration through a corresponding component such as a door. To remedy this situation, the sash are locked several times, so as to prevent the deflection. In addition, in the chambers between the Elements (frame / casement) used fire protection materials that react with appropriate temperature exposure with an endothermic reaction or foam and thereby prevent hot gases or flames penetrate through the chambers.

Both the use of special insulating profiles of fire protection materials, as well as the use of multiple locks are complex and therefore expensive and beyond prone to repair.

The invention has the object, starting from this prior art, to provide a door or a window with fire protection properties, which / at least significantly reduces the above-mentioned disadvantages, in particular the bimetallic effect of the profiles, both under ambient temperatures, as well as in case of fire. Fire protection means at least maintaining a fire protection 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 spars is made of a thermally non-separated profile. A thermally not separated profile is preferably a profile made of metal or a metal alloy, in which not two or more metal profiles or - shells are separated by one or more insulating bars or in which not one or more insulating profiles, the metal profiles of a composite profile from each other 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 fire. Doors or windows with fire protection properties are understood to be those which at least comply with the T-30 standard (fire protection or fire protection class) or more.

By a design according to the invention of a door or a window with fire protection properties with a sash without or with only partial thermal separation and a frame with thermal separation can in a particularly simple and thus advantageous to an expensive and complex to install locks and / or special insulation profiles Fire protection properties are waived.

The construction described, which is to be used for fire doors or windows, thus characterized in an advantageous manner by a significant cost advantage compared to the prior art, as can be dispensed with expensive multi-point locks and a correspondingly complex installation.

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

The insulating webs 28a of Isolierstegzone I are here-purely exemplary- in a plane. Alternatively, it is also possible for the insulating webs 28a of the insulating web zone I to be arranged vertically and / or horizontally offset from each other.

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

Preferably, the insulating webs 28a are web-shaped in cross-section and have thickened end portions 29. Preferably, each of the end portions 29 engages in a corresponding groove 30 of each one of the sub-profiles 24a, 25a, wherein the groove walls, the thickened end portions 29 of the insulating webs 28a in the x and y directions (see coordinate system in Fig. 2 ) preferably engage positively. The respective end portion 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 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) ), which has an outer structure, such as a knurling, which the shear strength in the profile direction (perpendicular to the plane of the Fig. 2 ) elevated. Alternatively, the end sections can also be inserted into the groove 30 with a suitable joining method without wire or the like.

The first sub-profile 24a is preferably separated from the second sub-profile 25a by a hollow chamber 31 which is formed in the first insulating land zone I between the two insulating webs 28a and the adjacent metal profiles 24a, 25a. As a result, from an outer side of the first partial profile 24a to a second outer side of the second metallic outer profile 25a, a number of hollow chambers 26a, 31, and 27a are formed, which provide good thermal insulation. The second partial profile 25a has a web 32a, wherein at the end of the web 32a a groove 33a for receiving a seal (not shown here) is provided.

The invention is based on the in Fig. 2 illustrated variant, but also on a composite profile 5b feasible, in which two partial profiles 24b, 25b (inner profile and outer profile) and a metallic center profile 35 (not shown here) via two Isolierstegzonen I, II are connected to one or more insulating webs 28b.

In Fig. 3 an embodiment of the door 1 is shown. The horizontally extending frame spar 14b of the frame 3b is made here of a composite profile 5b.

In order to avoid repetition, only deviations or changes and additions to the above-described embodiment variant of a composite profile 5a according to the invention will follow in the following Fig. 2 described.

The composite profile 5b has a first partial profile 24b, in which in this case at least one hollow chamber 26b is formed, and a second partial profile 25b, in which also preferably at least one hollow chamber 27b is formed. In addition, the composite profile 5b has a metallic center profile 35, in which also preferably at least one hollow chamber 36 is formed. The metallic profiles 24b, 25b, 35 may alternatively be designed without pronounced hollow chambers 26b, 27b, 36 or have a plurality of hollow chambers.

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

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

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

The first sub-profile 24b is preferably separated from the center profile 35 by a hollow chamber 37 which is formed in the first insulating land zone I between the two insulating webs 28b and the adjacent metal profiles 24b, 35b. The second sub-profile 25b is preferably separated from the middle profile 35 by a hollow chamber 38 which is formed in the first insulating land zone II between the two insulating webs 28b and the adjacent metal profiles 25b, 35b.

As a result, from an outer side of the first sub-profile 24b to a second outer side of the second sub-profile 25b, a series of hollow chambers 26b, 37, 36, 38 and 27b are formed, which ensure good thermal insulation. The second sub-profile 25b has a web 32b, wherein at the end of the web 32b, a groove 33b for receiving a seal (not shown) is provided.

The thermally not separate profile 4 of the casement 2 and the composite profile 5a, 5b of the frame 3a, 3b form in the closed state of the door 1 a rebate 34a, 34b. The fold region 34a, 34b is not represented by the seals here), for which the grooves 18 or 33a, 33b are provided, sealed against the environment.

According to the invention, the window frame 3 a, 3 b is designed to be thermally separated from the casement 2, so that no temperatures above 140 ° occur on the side of the door 1 a, 1 b facing away from the fire.

The construction described, which is to be used preferably for fire doors, is characterized in an advantageous manner by a significant cost advantage, as can be dispensed with expensive multi-point locks and a correspondingly complex installation. The majority of these doors (about 90%) is anyway installed in the interior of buildings, so that the disadvantages of a thermally unseparated construction, as they occur in an arrangement of such doors in the building envelope, hardly or not come to fruition.
