Description

The present invention relates to a partition wall for forming a fire compartment in rooms of buildings, with at least one wall and / or ceiling connection element and at least one single wall element for closing an opening, in particular a door or a window, with a door leaf or a window leaf.

Various partition wall solutions, in particular for fire protection purposes, are known in the prior art. Such partition walls, which are usually formed from the same or identically constructed individual wall elements, are used, for example, in the division of rooms in buildings, also in the formation of a fire compartment in rooms in buildings, for example to separate a usable room of a building from an escape or rescue route of the building . The partition wall can have stationary single wall elements and / or at least one single wall element designed as a door leaf or window leaf.

Doors or windows as devices for closing an opening are likewise known in numerous configurations in the prior art. The door leaf of a door or the window leaf of a window usually strikes against a stop in the closed state of the door or the window, which can be provided with a seal. The stop itself is usually provided or formed by a door or window frame or a door or window frame. In the case of a double-leaf door, the stop is usually formed by the exposed abutting or narrow surfaces of the two door leaves, which for this purpose have stepped rabbets which interact with one another when the double-leaf door is closed. Usually, the joint or narrow surface of the door or window leaf connecting the side edges of the side surfaces of the door or window leaf and, accordingly, the surface of the stop for the door or window leaf of a single surface running perpendicular to the side surfaces or with a step-like projection or recess, so-called step rabbet, formed.

In the case of the previously known partition walls, the vertical abutment surfaces of adjacent individual wall elements are, for example, tongue and groove-like, in particular in order to be able to meet the requirements for smoke and / or fire protection in the room-separating state or in a room-separating position and in the event of a fire, smoke- and / or prevent fire by sealing. Solutions are also previously known in which the vertical abutment surfaces of the individual wall elements of a partition wall butt against each other and remaining joints between the abutment surfaces of the individual wall elements of the partition walls are puttied or filled.

In the case of the previously known partition wall solutions, the areas of the abutting surfaces of the individual wall elements arranged next to one another are critical in the event of a fire, especially since there can be at least indirectly increased temperature loads in these areas due to the generally non-homogenized structures. An increased temperature load in this area has a particularly disadvantageous effect on the smoke and / or fire protection properties of the previously known partition walls, in particular since this reduces the fire resistance period. In addition, the individual wall elements of the partition walls known from the prior art generally have the same structure with the same materials, especially since the use of individual wall elements made of different materials and / or with different structures, especially in the area of the vertical abutting surfaces of adjacent individual wall elements, has a different and can cause unforeseeable or controllable deformation behavior, which is not acceptable and functional for smoke and fire protection reasons. A further disadvantage of the known partition walls is that the design options are limited by the use of individual wall elements of the same material and / or the same design.

The same applies in particular to doors or windows which are previously known from the prior art, in particular designed for fire protection purposes, as devices for closing an opening. Such door leaves or window leaves usually have a glass pane, in particular a fire protection pane. The glass pane or fire protection pane is generally arranged in a circumferential frame and in particular by means of grooves formed in the frame and / or by means of so-called grooves on the frame arranged glass retaining strips held. The glass pane, in particular the fire protection pane, is integrated in the frame.

Since fire protection panes have a relatively high dead weight, for example up to 120 kg / m ² and more, depending on the respective fire protection requirements, corresponding door leaves or window leaves are exposed to high loads, especially during opening and closing processes. In order to be able to hold such fire protection panes securely, the frame and any glass retaining strips used for corresponding door leaves or window leaves are usually constructed with profile elements. Such a glass door for fire protection purposes is for example from EP 0 803 634 B1 known, in which the fire protection pane of a door leaf is held on its four sides with the frame for the fire protection pane forming profile elements. The four profile elements, two profile elements running horizontally to the ground, also called friezes or transverse friezes, which are usually somewhat wider, and two side profile elements running vertically to the ground, which are generally somewhat narrower, have grooves for this purpose , in which the fire protection pane can be inserted and / or are provided with glass retaining strips to fix the fire protection pane on the profile elements. The construction of the frame with four profile elements and sometimes glass retaining strips is therefore quite complex.

Due to the construction of the previously known doors and windows, especially for fire and / or smoke protection purposes, the profile elements, in particular support profiles and / or glass retaining strips, also stand out or protrude above the glass pane, in particular fire protection pane, which in particular enhances the overall aesthetic impression of the Door leaf or window leaf as well as the door or the window and / or the overall aesthetic impression of the partition is impaired. In addition, the light cut-outs provided by doors or windows are usually critical, since these interrupt the overall construction. Fire tests have shown that in the event of a fire in the transition areas from the fire protection pane to the profile elements of frames or glass retaining strips, the profile elements can burn through, in particular because the path for the fire is shorter. Such a burn through is extremely critical and has a particularly detrimental effect on the fire or fire resistance duration, especially since the required room closure from one room to another can no longer be maintained.

Furthermore, so-called all-glass doors are known from the prior art, in particular for fire protection purposes, which are used to avoid the passage of fire and smoke in the event of a fire from one room to another. In such all-glass doors for fire protection purposes, the door leaf is formed from a single fire protection pane without further frame parts. Due to the design as an all-glass door, the design options are particularly limited.

Against this background, the present invention is based on the object of providing a partition wall for forming a fire compartment in rooms of buildings, which avoids the disadvantages known from the prior art and is improved with regard to the design options, so that in particular greater variability with regard to Structure and / or materials is made possible and at the same time the requirements of smoke and / or fire protection are met.

• at least one wall and / or ceiling connection element, preferably for fire protection purposes and / or smoke protection purposes,
  and
• at least one single wall element
  to close an opening,
  in particular a door or a window, with a door leaf or window leaf, preferably for fire protection purposes and / or smoke protection purposes,
  which has at least two horizontally and / or vertically aligned individual elements arranged side by side,
  in which
  • at least one of the at least two individual elements is a pane of glass, preferably a fire protection pane,
  • at least one of the at least two individual elements is a non-combustible building material board and / or a fireproof wooden element,
    and
  • the individual elements are flush and form-fittingly connected to one another,

in which
when the door or window is closed
the side surfaces of the at least one wall connection element
and
the side surfaces of the at least one door leaf or window leaf run flush in one plane.

The invention also relates to a partition wall of the aforementioned type, wherein the at least one single wall element and / or one or more further single wall elements is or are provided by a stationary single wall element, so that the side surfaces of the at least one wall connection element and / or the ceiling connection element and the side surfaces of the or the individual wall elements run flush in one plane. In this respect, the subject matter of the invention is also a partition wall according to the invention with only a single wall element, such as, for example, a single-leaf door.

A fireproof wooden element in the sense of the present invention is a wooden element which, in the event of a fire, maintains the required room closure from one room to another for a certain period of time. The functional integrity of the room closure, i.e. the separation of the rooms, in the event of a fire, is advantageously from over 30 minutes to over 180 minutes.

Because, according to the invention, the side surfaces of the at least one wall connection element and the side surfaces of the at least one single wall element, in particular the side surfaces of the at least one door leaf or window leaf as a single wall element, run flush in one plane, the flush design according to the invention advantageously has a smaller surface, so that In the event of a fire, there is a smaller area of attack and the resistance period is improved.

Another embodiment of the invention is characterized in that in the closed state of the door or the window, the side surfaces of the at least one ceiling connection element and the side surfaces of the at least one door leaf or window leaf run flush in one plane.

Another advantageous embodiment of the invention is characterized in that the exposed abutment surface of the wall connection element and / or the ceiling connection element connecting the side edges of the side surfaces of the wall connection element and / or the ceiling connection element has or forms a stepped fold.

These further measures according to the invention, individually and / or in combination with one another, advantageously achieve a further reduction in the temperature loads otherwise present in the event of fire, in particular since there are advantageously no protruding elements in the transition areas, so that the resistance duration in the event of fire is further improved .

The connection of the individual elements advantageously makes the use of otherwise load-bearing or holding profile elements unnecessary. Advantageously, either the vertical or horizontal profile elements extending to the ground are omitted. According to the invention, the fire protection pane lying flush with or in the respective door leaf or window leaf surface is therefore only held on two sides according to the invention, instead of four sides as in the prior art. A preferred embodiment of the invention provides, in particular otherwise in the prior art, to dispense with profile elements running horizontally to the subsurface as transverse friezes, so that the passage of light and the design options can be further improved. Furthermore, the flush and form-fitting connection of the individual elements of a single wall element provided according to the invention advantageously prevents increased temperature loads that would otherwise occur in the event of fire, in particular in the transition areas from the fire protection pane to protruding profile elements of frames or glass retaining strips, so that the resistance duration in the event of fire is further improved. By joining a door leaf or window leaf according to the invention from different fire-resistant or non-combustible materials, the design options can be significantly increased, and in particular the passage of light can be further designed. A combination of different materials, especially a change and / or combinations of transparent and non-transparent individual elements of a single wall element thus in particular enables more extensive designs of light effects of buildings and / or rooms.

Advantageously, the single wall element, in particular as a door leaf or window leaf, can be combined or joined together in a modular manner or in the manner of modules made up of individual elements from a fire protection pane and a non-combustible building material panel or a fireproof wooden element.

A further advantageous embodiment of the invention is characterized in that at least one of the exposed abutment surfaces of the individual elements joined together to form a door leaf or window leaf has or forms a step rebate, preferably an exposed abutment surface extending perpendicular to the substrate or to the ceiling of a room and which forms a door leaf or Window leaf assembled individual elements of a single wall element.

Another advantageous embodiment of the invention is characterized in that the rebate of the wall connection element and / or the ceiling connection element and at least one rebate of the door leaf or window leaf are designed to correspond to one another, preferably such that the rebate of the wall connection element and / or the ceiling connection element has a stop for provides the door leaf or window leaf as a single wall element.

The at least two individual elements of an individual wall element, in particular of the individual wall element of the door leaf or window leaf, are advantageously glued together in a fire-proof manner. The bonding is advantageously such that even individual elements of a single wall element, which sometimes have a very high dead weight, are securely connected to one another and held for fire protection purposes, in particular also in the event of a fire. A fireproof bond in the sense of the present invention is a bond which, in the event of a fire, maintains the required room seal from one room to another room for a certain period of time. The functional integrity of the room closure, i.e. the separation of the rooms, in the event of a fire, is advantageously from over 30 minutes to over 180 minutes. The adhesive for bonding is preferably a silicone, in particular a two-component silicone. It is advantageously suitable for bonding a pasty high-temperature adhesive that can be used up to a temperature of 1000 ° C and is characterized by a particularly high adhesive effect. Advantageously, the structure of the adhesive is particularly suitable for use in fire protection elements, such as a non-combustible building material panel or a fire-resistant wooden element, in which at least one of the abutting surfaces to be glued is provided with an absorbent structure.

Another advantageous embodiment of the invention provides that the at least two individual elements of a single wall element, in particular the door leaf or window leaf as a single wall element, are glued together in a fireproof manner using a sealing arrangement, preferably a sealing profile, between the two individual elements of a single wall element. An elastically deformable material can also be used as the sealing arrangement. The sealing arrangement, in particular the sealing profile and / or the elastically deformable material, preferably suffice for smoke and / or fire protection purposes, in particular in accordance with DIN 4102 or DIN EN 13501 or DIN 18095 or DIN EN 1364-3.

In an advantageous embodiment of the invention, the horizontally and / or vertically running abutting surfaces of two individual elements of an individual wall element arranged next to one another are essentially truncated. Individual elements of an individual wall element, which are essentially truncated at the abutment surfaces, can be manufactured particularly easily and inexpensively and, moreover, can be connected to one another particularly simply and inexpensively according to the invention, in particular assembled in a modular manner.

The same applies accordingly to the individual wall elements designed in this way. Advantageously, however, individual wall elements are also provided for a partition wall according to the invention, in which the vertically running abutting surfaces of two individual wall elements arranged next to one another each have a corresponding stepped rabbet, in particular in order to be able to achieve a further improved seal between two individual wall elements arranged next to one another.

In a further advantageous embodiment of the invention, at least one of the exposed abutting surfaces of the invention to a door leaf or

Window leaf assembled individual elements of a single wall element on a rebate, preferably an exposed abutment surface running perpendicular to the substrate of the individual elements of a single wall element assembled to form a door leaf or window leaf. The stepped rebate further improves the sealing of the door leaf or window leaf from a corresponding frame, from another door leaf in a double-leaf door or from another adjacent stop or wall connection element. The stepped rebate advantageously has a seal or sealing arrangement which, when the door leaf or window leaf is closed, further seals the gap between the door leaf or window leaf and the stop interacting therewith, in particular a wall and / or ceiling connection element.

If a door leaf is used for a double-leaf door, the step rebates of the two door leaves advantageously form the central stop of the double-leaf door. In a further embodiment of the invention, the sealing arrangement of the stepped rabbet formed according to the invention is preferably a sealing profile made of an elastically deformable material, which preferably meets smoke and / or fire protection purposes, in particular in accordance with DIN 4102 or DIN EN 13501 or DIN 18095 or DIN EN 1364-3.

In a further advantageous embodiment of the invention it is provided that the fire protection pane of an individual element of an individual wall element consists of a composite of at least two glass panes arranged parallel to one another, between which at least one fire protection layer is arranged. The fire protection pane is preferably designed in such a way that it satisfies or fulfills DIN 4102 or DIN EN 13501. Such a fire protection pane which is suitable for smoke and / or fire protection purposes advantageously prevents the passage of fire and / or smoke from one fire compartment or room into another fire compartment or room. In the event of a fire, the fire protection layer between the parallel panes of glass is activated, which absorbs the thermal radiation and creates a highly effective insulation layer. In the present invention, fire protection glass or fire protection panes according to so-called water glass technology and / or according to so-called gel technology can advantageously be used or used for the individual elements of a single wall element. used. In the case of a fire protection pane according to water glass technology, the fire protection layer used is in each case between a plurality of glass panes, in particular materials containing an alkali silicate compound, which act as foaming agents and foam up in the event of a fire. In the case of a fire protection pane using gel technology, the fire protection layer, which is arranged between two glass panes and which is activated in the event of a fire, is formed from gel-like materials, in particular organic polymers. In gel technology, the two glass panes of the fire protection pane are arranged at a distance from one another by means of a profile-like spacer forming an edge bond.

A further advantageous embodiment of the invention provides that the rebate of the door leaf or window leaf is formed or provided in that in the area of the lateral abutting edges of the door leaf or window leaf one of the glass panes of the fire protection pane jumps back over the other to form the rebate.

A further advantageous embodiment of the invention provides that the non-combustible building material board of an individual element of a single wall element consists of a base plate made of a non-combustible silicate material and a non-combustible decorative layer glued to the base plate, a cover layer of melamine resin preferably being applied to the decorative layer .

A variant embodiment of the invention provides that the non-combustible building material board or the fireproof wooden element has two base plates which are arranged parallel to one another and are spaced apart from one another by means of a spacer arranged between the base plates. The spacer advantageously stabilizes the base plates of the non-combustible building material panel or of the fire-resistant wooden element in the event of a fire. The spacer provided according to the invention between the base plates of an individual element of an individual wall element, which is designed as a non-combustible building material panel or as a fireproof wooden element, advantageously enables essentially the same deformation behavior of the corresponding individual elements or individual wall elements and thus contributes to a further improvement in the smoke and / or fire protection properties at. The spacer is advantageously firmly connected to the respective base plates, preferably by means of a full-surface adhesive bond. As a result, the spacer does not stabilize them combustible building material board or the fireproof wooden element, so that the deformation behavior or the warpage behavior of the base plates in the event of fire is largely standardized and thus further improved. This further improves the design options of the solution according to the invention, in particular for smoke and / or fire protection purposes. The spacer that stabilizes the non-combustible building material panel or the fireproof wooden element, in particular in the event of fire, is advantageously profile-like made of a wooden material, a composite material made of wood and steel, or a composite material made of calcium silicate and steel and / or wood. Furthermore, the use of preferably non-flammable plastic profiles, preferably glass fiber-reinforced plastic profiles, is provided as spacers.

Advantageously, the base plates of the non-combustible building material board consist of a non-combustible silicate material and a non-combustible decorative layer glued to the respective base plate, a cover layer of melamine resin preferably being applied to the decorative layer.

In a further embodiment of the invention, the base plates of the fireproof wooden element are made of solid wood and / or a wooden material. Wood-based material in the context of the present invention is understood to mean in particular materials that are produced by comminuting wood and then joining the structural elements obtained in this way. The size and shape of the wood particles determine the type of wood material and its properties. The wood particles can also be connected to one another with or without a binder. Wood-based materials for the purposes of the invention are for example chipboard, fiberboard, plywood and / or the like.

In a further embodiment of the invention, the at least one wall connection element and / or the ceiling connection element is or are made of solid wood and / or a wood material.

Another embodiment of the invention provides that the individual elements of an individual wall element have a width and / or height of approximately 20 mm to approximately 1500 mm.

In the case of a door leaf or window leaf designed according to the invention, the glass pane used, in particular a fire protection pane, is flush with the door surface or window surface. The glass pane is butt glued to the side or horizontal friezes, which are formed by a single element made of a non-combustible building material panel or a fireproof wooden element. Apart from the gluing, no further fastening means are advantageously provided between the glass pane and the friezes, so that the glass pane is held in particular without glass retaining strips, without grooving the glass pane and without a four-sided holding frame for the glass pane. Advantageously, the glass panes are optionally glued on both sides with horizontal or vertical profiles. The glass pane then runs vertically between the horizontal profiles or horizontally between the vertical profiles over the respective length.

The door leaf or the window leaf is advantageously held by lateral hinges, in particular with pivot hinges arranged at the bottom and top or with hinges lying hidden.

Fig. 1 , FIGS. 2 and 3 show a first embodiment of a partition wall T for forming a fire compartment in rooms of buildings. Fig. 1 , FIGS. 4 and 5 show a second embodiment of a partition wall T for forming a fire compartment in rooms of buildings. Both the partition T according to the first embodiment ( Fig. 1 , FIGS. 2 and 3 ) as well as the partition T according to the second embodiment ( Fig. 1 , FIGS. 4 and 5 ) provide a room closure. The functional integrity of the room closure, i.e. the separation of the rooms, in the event of a fire is advantageously from over 30 minutes to over 180 minutes, preferably according to fire resistance class F30, F60, F90, F120 or F180 according to DIN 4102-2 or according to EN 13501.

The partition T has at least one wall connection element 13 (in Fig. 1 shown on the left), a ceiling connection element 3 (in Fig. 2, Fig. 3 or. Fig. 4, Fig. 5 shown above) and at least one single wall element, here at least three single wall elements EW1, EW2 and EW3. The individual wall elements EW1 and EW2 are each designed as a door leaf and in the present case form a double-leaf door. The single wall element EW3 is designed as a fixed single wall element. The wall connection element 13, the ceiling connection element 3 and the individual wall elements EW1, EW2 and EW3 are in the present case designed for fire protection purposes and / or smoke protection purposes. The partition wall T is designed according to the invention in such a way that the side surfaces SF of the at least one wall connection element 13 and the side surfaces SF of the individual wall elements EW1, EW2 and EW3 run flush in one plane.

The individual wall elements EW1 and EW2 are in the present case designed as a double-leaf door for fire protection purposes. Fig. 1 shows the double-leaf door formed from the individual wall elements EW1 and EW2 in a closed state. The single wall element EW1 forms the first door leaf 1a. The single wall element EW2 forms the second door leaf 1b.

The in Fig. 1 , FIGS. 2 and 3 The illustrated first embodiment of a partition wall T run in the closed state of the door, as in Fig. 1 shown, the side surfaces SF of the at least one wall connection element 13 and the side surfaces SF of the at least one door leaf 1a or 1b flush in one plane.

The in Fig. 1 , FIGS. 4 and 5 The illustrated second embodiment of a partition wall T run in the closed state of the door, as in Fig. 1 shown, the side surfaces SF of the at least one wall connection element 13, the side surfaces SF of the ceiling connection element 3 and the side surfaces SF of the at least one door leaf 1a or 1b flush in one plane.

In the present exemplary embodiments, the door leaves 1a and 1b of the double-leaf door each have three individual elements 2a, 2b and 2c arranged vertically next to one another. The individual elements 2a, 2b and 2c of the door leaf 1a and 1b are, as in particular with reference to FIG Fig. 1 recognizable, also connected to each other flush and form-fitting. For the purposes of the present invention, a form fit is a holding together of parts without constantly active forces, which is ensured by the shape of the parts, in particular by the fact that one part is "in the way" of the other part. The individual elements 2a, 2b and 2c are connected to one another by gluing 7 of the individual elements 2a, 2b and 2c with a fireproof two-component silicone that securely connects the individual elements 2a, 2b and 2c, preferably through its adhesive effect.

The individual elements 2a and 2c of the door leaves 1a and 1b are each formed from a fireproof wooden element (cf. in particular Fig. 1 ). The single element 2a of the in Fig. 1 Door leaf 1a shown on the left has a width of about 420 mm and the individual element 2c of door leaf 1a has a width of about 80 mm. The single element 2a of the in Fig. 1 Door leaf 1b shown on the right in the present case has a width of approximately 110 mm and the individual element 2c of door leaf 1b has a width of approximately 80 mm. Between the two individual elements 2a and 2c of the door leaf 1a and 1b, respectively, an individual element 2b designed as a fire protection pane is arranged flush and form-fitting with respect to the individual elements 2a and 2c.

The individual element 2b of the door leaf 1a or 1b, designed as a fire protection pane, as well as the individual wall element EW3 is, as in particular with reference to FIG Fig. 1 recognizable, in the present case composed of two glass panes 9 arranged parallel to one another and spaced apart from one another by means of a spacer 11, the space between the glass panes 9 being filled with a fire protection material 10, in this case a gel-like fire protection material. The single element 2b of the in Fig. 1 door leaf shown on the left 1a has in the present case a width of approximately 744 mm and the individual element 2b of the door leaf 1b a width of approximately 1054 mm.

The circumferential spacer 11 can be covered by edge printing 5 on the glass panes 9 of a fire protection pane, so that it is not visible from the outside.

The individual elements 2a, 2b, 2c of the individual wall elements EW1, EW2, in this case the door leaves 1a and 1b, are designed in such a way that the abutting surfaces S of two individual elements 2a, 2b, 2c arranged next to one another are essentially truncated. In a joint that sometimes occurs between the individual elements 2a, 2b and 2c after the gluing 7, a silicone 8 is inserted in the present case, so that the individual elements 2a, 2b and 2c are connected to one another in a flush and form-fitting manner.

The exposed abutment surfaces S of the individual elements 2c joined together to form a door leaf 1a or 1b each have a corresponding stepped rebate which seals the double-leaf door when the door is closed and thus forms a central stop of the double-leaf door shown. For this purpose, the respective rebate also has a seal 12.

The exposed abutment surfaces S of the individual elements 2a joined together to form a door leaf 1a or 1b each have a stepped rebate, which is formed with a correspondingly formed stepped rebate on the wall connection element 13 (as is the case with the individual element 2a of the door leaf 1a or individual wall element EW1) or on the side of the single wall element EW3 (given in the case of the single element 2a of the door leaf 1b or single wall element EW2) interacts as a stop in the closed state of the respective door leaf 1a or 1b and seals the door. For this purpose, the rebate also has at least one seal 12. In the first embodiment of a partition wall T according to Fig. 1 , FIGS. 2 and 3 the ceiling connection element 3 provides a stop for the door leaf 1a or 1b, in which a side surface SF of the ceiling connection element 3 (in FIGS. 2 and 3 the right side surface SF of the ceiling connection element 3) are not flush with the surface SF of the door leaf 1a or 1b. In the second embodiment one Partition T according to Fig. 1 , FIGS. 4 and 5 the ceiling connection element 3 provides a stop for the door leaf 1a or 1b, in which the side surfaces SF of the ceiling connection element 3 are flush with the side surfaces SF of the door leaf 1a or 1b.

The respective door leaves 1a and 1b each have a stop profile 13 with which they interact. To seal and prevent fire and smoke from spreading in the event of fire, a seal 12 is arranged on a fold formed by the stop profile 13, the seal 12 sealing the gap between this and the stop profile 13 when the door leaf 1a or door leaf 1b is closed .

The individual element 2a of the door leaf 1a has, as in FIG Fig. 1 Wall connection element 13 shown on the left has at least one recess for a receiving body of a hinge 14 for a concealed arrangement between door leaf 1a and wall connection element 13, so that a concealed arrangement of the hinge 14 is made possible. An embodiment of the invention not explicitly shown here is characterized in that the door leaf 1b can be configured or configured in accordance with the door leaf 1a with regard to the door closers and / or hinges.

The door leaf 1b after Fig. 1 is exemplarily arranged by means of pivot hinges 4 on a space-delimiting structure, not explicitly shown, in the present case floor and ceiling. In the floor area, the door leaf 1b in the present exemplary embodiment is also connected to a door closer, a so-called floor spring. An embodiment of the invention not explicitly shown here is characterized in that the door leaf 1a can be configured or configured in accordance with the door leaf 1b with regard to the door closers and / or hinges.

The two door leaves 1a and 1b have, as in FIGS. 2 and 3 or. FIGS. 4 and 5 shown as an example for door leaf 1a, each on their side facing the floor on a floor seal 6 to seal a gap between the door leaves 1a and 1b and the floor, so that the passage of fire and smoke is effectively prevented in the event of a fire.

In an embodiment of the invention not explicitly shown here, the individual elements 2a and 2c of the door leaf 1a or 1b are made from a non-combustible building material panel instead of a fireproof wooden element, which is provided with a non-combustible wood veneer as a decorative layer on its visible sides. If necessary, the decorative layer can be provided with a cover layer made of melamine resin.

In a further embodiment of the invention, not explicitly shown here, the individual elements 2a and 2c of the door leaf 1a or 1b are made up of two parallel base plates instead of a fireproof wooden element, which are spaced apart by a spacer arranged between the base plates. The base plates are each made of a non-combustible building material board and / or a fireproof wooden element. In the event of fire, the spacer stabilizes the base plates of the individual elements 2a or 2c.

A partition wall designed according to the invention, in which the side surfaces SF of the at least one wall connection element 13 and / or the ceiling connection element and the side surfaces of the individual wall element (s) EW1, EW2, EW3 run flush in one plane, in particular when a single wall element EW1, EW2 is designed as a door leaf 1a , 1b or window leaf, has the following advantages over the solutions known from the prior art:
Because, according to the invention, the side surfaces of the at least one wall connection element and at least optionally the ceiling connection element and the side surfaces of the at least one individual wall element run flush in one plane, the increased temperature loads that would otherwise occur in the event of fire, in particular in the transition areas from the wall connection element or ceiling connection element to the single wall element, are advantageously avoided prevented or significantly minimized, so that the resistance period is improved in the event of fire.

The individual wall elements EW1, EW2, EW3 of the partition wall T according to the invention, in particular as a door leaf or window leaf, are variable and advantageously modularly constructed or can be built up, so that a wide variety of designs and combinations of different individual elements 2a, 2b, 2c for Single wall elements EW1, EW2, EW3 are possible and conceivable. The partition wall T according to the invention can thus be adapted to the most varied of requirements with regard to light passage or aesthetics. For example, combinations of the configurations of individual elements 2a, 2b, 2c for individual wall elements EW1, EW2, EW3 are possible, with the individual wall elements EW1, EW2, EW3 each having several individual elements 2a, 2b, 2c arranged horizontally or vertically in alignment with one another, which in turn are vertical or horizontal are arranged in alignment with one another.

The exemplary embodiments shown in the figures of the drawing and the exemplary embodiments described in connection with them serve only to explain the invention and are not restrictive for it.
