Description

The invention relates to a thermally insulated wall element unit for building facades according to the preamble of claim 1.

Thermally insulated wall element units for building facades are known per se, such as window, roof or façade elements, even in pre-assembled design.

An essential goal of the construction of today's window and facade elements is their consistent and efficient summer and winter thermal protection.

From the state of the art - so from the DE 101 49 685 C1 - Are window or door elements are known to be pushed in front of the so-called sliding shutters for darkening or sun protection. For this purpose, guide rails are arranged above and below the window or door element on the outside of a building, on which the sliding shutters can be moved from the parking position to the functional position.

From the AT 400 063 B Furthermore, a window element is known which is inserted centrally into an opening of a building wall and to which a heat insulation in the form of a thermal insulation surface element connects on both sides. In each case outwardly and inwardly so-called magazines are arranged in the area of this thermal insulation, which are clad on both the outer wall and on the inner wall flush with the masonry. These magazines accommodate appropriate sliding elements that can close the interposed window for the purpose of burglary or for the purpose of protection against the cold, weather protection or light protection. Both outside and inside corresponding sliding elements can be arranged in the pocket-shaped magazines. The AT 400 063 B This shows a window that has pockets in an extended window reveal, in which there are sliding elements for different functions on the window. On the outside are burglar bars and thermal insulation sliding shutters arranged while on the inside sliding elements for the blackout or insect repellent or sunscreen are arranged.

The disadvantage of this is that the window element is fixed solely on the thermal insulation, which requires a special complex construction to ensure the determination of the masonry. In addition, each outside and inside separate sliding guides are required, which are separated by the thermal insulation of each other. Furthermore, it is problematic that the space inside pockets are not sufficiently ventilated, resulting in excessive condensation. Also problematic is the degree of contamination of the inner pockets occurring with time, which can not be remedied without dismantling the sliding sash. In addition to these problems, in particular the relatively complex installation of the window and the associated additional components on the building is to be mentioned as disadvantageous. Thus, the magazines for inside and outside and the window are to be mounted separately from each other, which also brings high costs due to the correspondingly high cost. In addition to the inefficiency of assembly, such a system also suffers from self-adjusting loss of functionality.

The invention has the object to remedy these disadvantages as much as possible.

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

According to the invention, a completely preassemblable wall element unit is created which can be used "as a whole" in a masonry opening or which can be used as a preassembled facade element of an elementary façade, wherein at least the functions mentioned in claim 1 or even more or further functions can be integrated into the wall element unit

According to the invention a simple and accurate pre-assembly of the wall element unit can be made independently of the building tolerances of the building.

The pre-assembled unit also improves the assembly of interlinked functional elements directly on the building, regardless of the building tolerances given in each case on the building. In this case, the function of the functional elements to each other permanently ensured and it is in a simple way, even in modern facades with room-high infills possible because it is only necessary, the wall element units suitable, especially room-high, to measure.

According to a particularly preferred embodiment, the at least one sliding element on a highly insulating surface area, with which it advantageously covers the window member for realizing an optimal thermal insulation in a sliding position against the outside air

It is advantageous if the window element is designed as a movable window, in particular that the window element is designed as a sliding window and that in the mounting frame another of the sliding guides is designed for sliding guide of the sliding window and / or if the window element as a tilting window or as a rotating window or as a rotation / Tilting window is formed and / or if the window element is designed as a fixed glazing.

It is advantageous if the mounting frame consists of plastic.

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

FIG. 1 shows a view of a schematically illustrated wall element unit 1, which has a circumferential and preferably circumferential cross-section Blend- or mounting frame 2 with two in the installed position vertical frame posts 2a, 2b and two horizontal frame posts 2c, 2d (see also Fig. 3 ).

The individual frame posts 2a, 2b, 2c, 2d can be interconnected by means of schematically indicated corner connectors 2e.

Preferably, the mounting frame 2 is made of plastic. It may be designed for mounting in a masonry opening or for combination with other laterally adjoining other wall elements, in particular facade elements and have one or more hollow chambers 2f for optimizing the thermal insulation and rigidity.

The frame limits a preferably rectangular area A.

In the peripheral mounting frame 2, a stationary surface element - hereinafter also called wall fixed part 4 - used in thermally insulated design that covers a portion of the surface A.

In addition, in the peripheral frame, a transparent wall part - hereinafter also called window element - used, which can be designed as a movable window element or as a fixed glazing. As a movable window element, it can be brought into an open and a closed state, so that it covers a further portion of the surface A in the closed state. It is essential that this part is transparent or translucent. The window element 3 has a casement 3a and a transparent disk element 3b

The transparent wall part - the window part - 3 may be a sliding element or a lifting sliding element in the case of a movable embodiment. Alternatively, it can also be designed as a turning window, as a tilting window, as a turn / tilt window or as another movable window element.
The transparent window element opposite is located in the frame, the non-transparent wall fixed part 4, which is preferably designed as a highly thermally insulated element and before the preferably outwardly a decorative plate 5 is set, which in turn is attached to the peripheral mounting frame 2.

On the inner circumference of the mounting frame 2, at least one or more sliding guides 113, 114, 115 are formed for sliding elements 123, 124, 125 arranged parallel to one another, to be described below.

These sliding guides 113, 114, 115 are aligned parallel to one another and preferably extend in the horizontal direction over the entire inner length of the mounting frame 2.

Preferably, between the decorative panel 5 and the wall fixed part 4, one or more of the layers of the sliding elements 123, 124, 125 are arranged, which are each guided displaceably in one or more sliding guides 113, 114, 115.

Preferably, the surface of the decorative panel 5 and the fixed wall part 4 are matched to one another such that only the fixed wall part 4 is covered with the decorative panel 5.

Between the fixed wall part 4 and the decorative plate 5 such a receiving space is formed, in which the one or more sliding elements 123, 124, 125th can be pushed in without them being visible from the outside of the building or from the inside of the building.

The sliding elements comprise at least one thermal insulation unit 16 for covering the transparent window 3. The thermal insulation unit 16 is always assigned directly to the fender element 16 or arranged in front of it. When closed, the gap between the thermal insulation element 16 and the profile bar 9 and the gap between the thermal insulation unit 16 and the mounting frame is sealed by means of suitable seals. The possibly further sliding elements or - layer need no thermal insulation and therefore can be arranged further out, which simplifies the entire structure and reduces the mounting frame to a minimum.

As a further sliding elements, the window element 3 per se, that in this case forms a sliding window (see Fig. 3 ), a sliding sunshade device 17 and / or a slidable light-guiding device, etc. may be provided.

FIG. 2 shows a largely too Fig. 1 Analog wall element unit, but in which the transparent wall part 3 and the window element 3 is a rotary, Drehkipp- or tilting element or parallel Abstellelement (window, door) 6. Alternatively, it is also conceivable to provide a fixed glazing instead of the window element 3.

FIG. 3 shows a wall element unit 1 according to Fig. 1 in horizontal section.

The mounting frame 2 as a frame has on its inner circumference - preferably towards the room inside - a here profiled 7, which is designed for mounting the wall fixed part 4, which is preferably a highly heat-insulating plate whose heat transfer coefficient of the glazing preferably clear below.

As can be seen, the mounting frame 2 may be provided with a preferably vertically extending latch profile 9, which divides the surface A into compartments, wherein one of the compartments is filled by the wall fixed part 4 and wherein the other Gefach is formed as a wall opening 8, which after Fig. 3 is not filled by a functional element, since the window element 3 is designed here as a sliding window. In the wall opening 8, however, is after Fig. 2 a turn / tilt window 6 used.

The bolt profile 9 preferably also has the profiling 7 of the window frame 2.

In each case, a peripheral profiling 7 for receiving the fixed wall part 4 and possibly the window element 3 (FIG. Fig. 5 ) educated.

The profiles of the mounting frame 2 and the locking rail 9 are preferably formed thermally insulated. Most preferably, they are made of a high strength plastic.

To the inside of the room are on the mounting frame 2 and the locking rail 9 support strips 10, 11 fastened, preferably by snapping on corresponding locking means of the mounting frame 2 and the support strips 10, eleventh

These support strips 10, 11 can be used for the installation of a room interior trim 12 and cover the free edge of the interior lining.

According to the embodiment of Fig. 3 the wall opening 8 is provided in the region of the profiling 7 with cover profiles 36.

The first profile groove 13 is used according to the horizontal section for receiving the first sliding guide 113, the after Fig. 3 is used to guide in the frame as a window 3 sliding sash and slidably Fig. 5 for slidably guiding the insulating board or insulating unit 16.

The sliding window sash can be moved to a position in front of the fixed wall part 4 to open the window and to a position in front of the wall opening 8 to close the window.

At least one further sliding guide 114, preferably the second sliding guide 114, which is relatively outward relative to the first sliding guide 113, is used after Fig. 3 for receiving the thermal insulation panel 16, which is displaceable in a position in front of the wall fixed part 4 and in a position in front of the opening 8, in order to create additional thermal insulation in front of the sliding window - for example, in a special cold and / or at night. In this position, the wall element unit 1 overall can have a heat transfer coefficient which corresponds to that of a thicker insulated building wall.

Finally, it is conceivable to use the third sliding guide 115 for further sliding elements 125, so for solar panels or surface elements 17 for sun protection or for light control or the like.

Depending on the number of sliding layers used, the mounting frame may optionally be provided with further sliding guides and corresponding grooves. If necessary, the simple use of attachable or frame profiles / adapter profiles 24 that can be latched to the frame profile instead of frame strips 18 is also suitable for expansion. which are mounted on the outside of the mounting frame 2, for example latching or screwing ( Fig. 5 and 6 ) and thus form a quasi broadening of the mounting frame 2 to the outside.

To Fig. 7 are complementarily exemplified two further sliding guides 116, 117 formed on grooves 20, 21 on the adapter profiles 24, the structure of which may correspond to the other sliding guides. These sliding guides serve to receive further sliding elements 126, 127.

In FIG. 3 serves the additional frame of the frame strips 18 only the recording of the decorative plate 5, which may consist of various materials and is preferably dimensioned such that they are the "in park position" sliding layers covers. The decorative panel 5 may be formed according to an advantageous variant as a photovoltaic element.

The individual sliding layers 123, 124,... Can be moved manually from the parking position into the functional position, but also by motor.

The decorative panel 5 can be fixedly mounted or moved by hand for the purpose of revision in the frame strip in which it is locked.

The sliding guides 113, 114, 115 will be described in more detail below. They comprise profile grooves 13, 14, 15 on the inside of the mounting frame. 2

The profile grooves 13, 14, 15 serve in the horizontally extending profile post of the receptacle for realizing the actual functional elements of the sliding guide. In the vertical profile grooves 13, 14, 15 other functional elements can be used.

Thus, in the from the room inside to the room outside (ie in Fig. 3 from right to left) first vertical profile groove 13 of the frame profile each profile strips 19 may be used, which serve to cover or for sealing contact with the glass sliding sash (3) (transparent wall part).

The same applies to the insulating unit 16 designed as a sliding element, which preferably completely covers the transparent window sliding panel 3. The frame, both of the transparent sliding leaf 3 and the sliding insulation unit 16 - (insulation layer - are thermally insulated and made in particular of high-strength plastic.

FIG. 4 shows a vertical section through the assembly 1. In the profile grooves 13, 14, 15 support or guide profiles are used, which take over the leadership of the sliding layers used and the sliding sash.

The FIG. 5 shows the horizontal section according to FIG. 2 , By means of additional profiles 3a and seals in the wall opening 8, a sash 20 or a fixed glazing with a disc 3b is used.

Instead of the window sliding wing 3 according to FIG. 3 and 4 is now the Dämmlayer 16 moved into the plane of the profile groove 13. Accordingly, the other function sliding wings or layers then move into alignment with the next profile grooves 14, 15.

The same applies to the FIG. 6 , which in turn shows a vertical section through the unit 1.

The FIGS. 7 and 8th again show a vertical and a horizontal section through the assembly 1 according to the Figures 3 and 4 , wherein the frame 2 is supplemented by the metal additive adapter profiles 24 already mentioned, the further guide grooves 22, 23 have to supplement other Funktionsschiebelayer.

The FIGS. 9, 10 and 11 in essence, the Figures 1 and 2 and are supplemented by the Figures 9.1, 10.1 and 11.1 ,

The Figure 9.1 shows the unit in a simplified horizontal section, with the sliding layers are all in the parked position. The transparent wall part 3 is freely accessible in the daily position.

In the FIG. 10.1 is the daily position shown, with the assumption of sunshine. Here, the Dämmlayer or the Dämmeinheit 16 is in parking position, while the layers 17 and 17 ', for example, for the sun protection and for the light control in front of the transparent wall part 3 are positioned.

The Figure 11.1 shows the night position in which the insulating layer or the insulating unit 16 covers the transparent window element 3 to the outside.

The same applies if between Dämmlayer 16 and the window wall a transparent sliding sash is provided.

As a sliding layer 17, a semitransparent photovoltaic module can be used for the sunscreen, which also contributes to the generation of energy in addition to the translucent shading.

Hereinafter, the structure of the sliding guides with reference to Fig. 12 and 13 explained in more detail.

The profile grooves 13 to 15 and the grooves 22, 23 of the adapter profiles 24 for frame extension of the mounting frame 2 are identical U-shaped.

The grooves 13-15 and 22, 23 are U-shaped, with projections 35 arranged on the walls for supporting and positively locking strip-like profile inserts 26 for guiding, supporting and centering the various functional layers (functional units). The profile inserts 26 have webs 26a, b, which are aligned at an angle to each other and serve to initiate the weight of the sliding elements in the lower horizontal guide profiles.

The groove base runs trapezoidally and forms in the groove bottom at the transition to the frame profile base of the profile 2a a screw 27, which are used in addition to the corner connectors 2e for frame connection, in particular for prefixing. The screw groove 27 is formed undercut and is optionally additionally used for retaining clips for holding cables, etc. (not shown here).

In the vertical posts ( Fig. 3 ), the already mentioned profile inserts 19 are provided which either the grooves 13, 14, 15 close or have centering inserts, which take over the centering and sealing of the functional layer in the operative position.

Horizontal top and bottom identical profile inserts 26 are used as support elements, which are supported near the groove bottom on the Nutwandungen.

They each receive a guide profile 29, 30, e.g. the metal runner rail, preferably made of stainless steel, wherein the lower guide profile 29 is configured such that the rollers 31 of the functional layer are placed on it and guided or directly make the guide of the functional layer on top of the frame and wherein the upper guide profile 30 drive belts 32, Ropes or chains, which are needed for driving the functional layer.

The guide profiles 29, 30 have sealing surfaces 33 against which the seals 34 of the functional layers come to rest.
