Description

The invention relates to an outer wall system of a building having a movable outer wall according to the preamble of claim 1 and a method for installing an outer wall system according to the invention in an existing building.

Exterior wall systems are executed in the construction sector in various embodiments, for example, in new buildings of blocks of steel or reinforced concrete in skeleton construction. In this construction, a load-bearing skeleton of floor slabs and vertical columns is made to discharge the loads, in which non-bearing infills are used. The protective outer wall or the facade of the building is attached as a non-load-bearing element only after completion of the shell to the supporting parts of the building.

For this purpose, predominantly individual, prefabricated facade elements or facade systems, for example made of glass, metal or plastic are used, which are attached to the load-bearing structure of the building and connected with sealing elements to form a dense outer wall. The wall elements are pre-assembled at the factory and provided with window elements, heat and sound insulation, ventilation elements or, for example, shading options, so that assembly on the construction site can be significantly shortened. Through a variable system of individual exterior wall elements, an individual adaptation and design of the exterior wall or the facade is possible.

In addition to being used in new buildings, exterior wall systems are becoming increasingly important in the refurbishment and modernization of existing buildings. By replacing existing facades or exterior walls with new exterior wall systems with better insulation properties, better insulation of existing buildings is possible in addition to a corresponding architectural design, so that considerable energy savings can be achieved.

From the generic FR 2 730 259 A1 an outer wall system is known in which by means of linear rails, a wall is displaceable perpendicular to its extension plane to separate living and terrace area variable.

The DE 101 02 287 A1 describes a device which allows a permanent displacement of non-load-bearing walls in enclosed spaces.

The DE 10 2009 011 220 A1 shows a building of two box-like, nested units that form the side walls of the house. By more or less wide nesting of the units, the size of the living space can be changed.

A stored on roles shelf partition wall system proposes the EP 1 654 958 A1 in front.

A perpendicular to their extension plane of linear guides movable folding wall is in the FR 1 103 510 A disclosed. A similar system suggests the WO 2007/083922 A1 before, but here racks for motorized adjustment and for folding the wall along the side walls are attached.

The present invention provides an exterior wall system for a building that provides new architectural design possibilities.

The outer wall system according to the invention of a building according to claim 1 has a movable outer wall and a bearing for the movable outer wall, wherein the movable outer wall separates an inner space from a walkable outer space, reversibly adjustable between at least two closing positions and lockable in each of the closed positions and in each of Closing positions separates the interior to the outside. The bearing has at least one rail in which the movable outer wall is displaceably guided, wherein the rail is configured such that the movable outer wall is movable between an inner closing position and an outer closing position, and in the outer closing position at least part of the outer space in the interior passes over and increases its footprint with it. The rail, viewed in the plan of the building, forms a trajectory and runs on the floor and / or the ceiling. Alternatively, the rails are provided on the opposite side walls and each form a trajectory in side view. The movable outer wall is along the Trajectory between its closed positions movable and is adjustable when passing through the trajectory in an intermediate position in which it extends along a the outer and the inner wall at least partially defining side wall or along the ceiling, in the intermediate position outer space and interior completely merge into one another.

The interior is here, for example, a living room of a building, which is separated by the movable outer wall to the outside. The movable outer wall fulfills all functional requirements for an outer wall, so that the interior is protected from external influences, for example moisture, wind, temperatures, in any of the closing positions in which the outer wall can be locked. The walk-in outdoor space is especially a balcony, a loggia or a terrace, which is accessible from the interior or from another room. In the inner closed position, the outer wall is arranged between the inner space and the outer space, so that the outer space and the inner space are separated by the outer wall and the outer space communicates with the surroundings. In the outer closed position, at least part of the outer space or the entire outer space passes into the inner space, so that it is separated to the outside. The floor space of the interior is thus increased, so that a larger air-conditioned space is available. The outer wall system according to the invention thus allows a more flexible use of space of the building: The outer space can be used depending on the closed position either as a heated interior or unheated outdoor space. In winter, for example, the balcony can be used as a fully fledged living space and in summer as an open space. Due to the simple structure of the exterior wall system according to the invention in the construction of new buildings, as well as in the renovation and modernization of existing buildings can be used. By appropriate insulation of the outer wall system, an improvement of the thermal insulation is also possible in existing buildings.

The rail forms a trajectory in the floor plan of the building and runs on the floor and / or the ceiling. The outer wall is movable along the trajectory between the two positions, preferably as a whole, so that it can be moved in a very space-saving manner from a closed position to a second closed position. It is only necessary that the room between the rail at the bottom and the rail at the ceiling is kept free. Any furnishings designed for outdoor use do not need to be moved.

The movable outer wall is, as mentioned above, adjustable in an intermediate position in which it extends along an outer or the inner wall at least partially defining wall or along the ceiling. In this intermediate position, the outdoor space and the interior are completely intertwined, creating a completely open space that offers a pleasant living environment in summer months.

In order to further increase the flexibility and facilitate the displaceability of the outer wall, the movable outer wall preferably has a plurality of wall elements. These may be provided separately and provided with sealing elements, so that they are individually movable and can be assembled in each of the closed positions to a dense outer wall. But the wall elements can also be coupled in particular pivotally with each other.

In the embodiments shown in the later figures, the operation and use of the system according to the invention is improved in that the inside of the outer wall is in a closed position to the outside of the outer wall in the other closed position, so that the outer wall is turned between the closed positions, which by the Trajectory is possible.

The wall elements can, for example, be coupled together in such a way that they can be moved as one unit and a displacement of the outer wall from a closed position to a second closed position is facilitated. The coupling can be done for example via hinges or other movable connecting elements.

The movable outer wall preferably has at least one window and / or a closable door, which optionally opens the interior to the exterior. The exterior space can be accessible through a door, for example, from the interior. In addition, the windows ensure sufficient exposure of the room.

The movable outer wall is mounted horizontally or vertically movable. The outer wall can be moved either horizontally, for example via a side wall or vertically, for example, over the ceiling of the room from a closed position to a second closed position.

Preferably, the bearing comprises at least one parallel pair of rails.

The outer wall is perpendicular or transversely to its plane of extent, preferably as a whole, movable between its closed positions.

The rails of the rail pair are arranged on opposite sides of the outer wall, so that the outer wall is securely guided in the pair of rails. The outer wall can be moved as a whole, but it is also conceivable that in each pair of rails a wall element of the outer wall is guided.

In a preferred embodiment, the trajectory is U-shaped or curved in plan view of the building. The trajectory of the rail is preferably selected such that it extends in sections along a wall adjacent to the displaceable outer wall so that it can be parked in an intermediate position in which the outer wall runs along the wall of the room.

In a second embodiment, the rails are provided on or in opposing fixed walls, and the movable wall is vertically movable between the closed positions. The movable outer wall can be moved from a first closed position vertically over the ceiling of the room in the second closed position. Since there are no rails on the floor or the ceiling, this can be fully utilized. In addition, no precautions are necessary to protect especially the rail on the ground from contamination.

To ideally integrate the storage of the exterior wall system into the room, it is flush with the room and / or the floor of the room. The storage is completely embedded in the ceiling or in the ground, without getting over.

The outer wall of the outer wall system can be moved manually from a closed position to a second closed position. But it is also conceivable that a motor drive and a controller are provided to move the movable outer wall from an outer closed position to the inner closed position.

The control can be manually, time-controlled or activated by sensors. The outer wall can be moved, for example, depending on climatic conditions, such as precipitation, wind or corresponding temperatures or depending on the time of day.

According to the preferred embodiment, the outer wall system may have an additional, later to be attached base plate and ceiling plate, which already have the storage. The installation of the outer wall system is so much easier, especially for renovations, since no complex fitting of storage in the existing site ceiling or in the floor of the room is necessary. It is only necessary to attach the additional ceiling panel or floor panel to the building. This results in such a fast-mountable module of variable components. The loads imposed by the movable outer wall on the ceiling or the floor of the building can be introduced into the building over the entire surface of the additional floor slab or ceiling slab. The bottom plate and / or the ceiling plate allows, for example, the compensation of bumps on the ceiling and / or the floor of the building, so that a flat surface is created for storage and provides the necessary insulation.

It is also conceivable that the outer wall system has two opposite side walls that connect the ceiling plate and the bottom plate. The side walls can on the one hand support the ceiling plate, so that no complex attachment of the ceiling plate in the ceiling of the building is necessary, on the other hand, it is conceivable to arrange additional lines or insulation in the side walls, for example, to allow better thermal insulation of the interior. On the subsequent floor, ceiling and side walls of the enlargeable room is isolated.

Preferably, the bottom plate, the top plate and the side walls each form a self-supporting structure and preassembled unit. This preassembled unit can be designed as a retrofit on a house-side floor slab, ceiling slab or side walls mountable or externally mounted to the building wall unit is factory pre-assembled, delivered as a unit and used for example with a crane from the outside into the building or mounted on this. The assembly time on the building can thus be significantly reduced.

The units are preferably multi-layered and contain insulation.

The bottom plate, the ceiling plate and the walls can even form together a prefabricated box-like unit that can be retrofitted on an existing balcony, a terrace or a loggia or mounted on the outside of a building wall, which facilitates the renovation of large prefabricated buildings.

The bottom plate, the ceiling plate and / or the side walls are preferably placed on a house-side floor panel, a ceiling panel or side walls. As a result, no elaborate preparatory work is necessary on the existing building.

But it is also conceivable that outside of the building supports, supports or other mounting options are provided and the bottom plate, the ceiling plate and / or the side walls are secured thereto, so that the outer wall system is completely outside mounted on the outer wall of the building.

In order to enable a thermal insulation of the interior in each of the closed positions, an insulation is provided between the bottom plate, the ceiling plate and / or the side walls of the outer wall system and the house-side bottom plate, ceiling plate or the house-side side walls. Since the insulation is mounted with the exterior wall system, a simple insulation of the building is possible without complex work on the building.

It is conceivable that the side walls, the ceiling plate or the bottom plate have integrated lighting elements and / or electrical connections.

In addition, the outer wall system may have heating or cooling elements, which are integrated in particular in the ceiling plate, the bottom plate and / or the side walls.

The exterior wall system also has water drainage channels. These allow in the inner closed position of the outer wall drainage of water from the outside. In the outer closed position of the outer wall, the water drainage channels are closed to the interior, so that no water can penetrate from the outside into the interior.

The bottom plate is formed, for example, placed on a house-side bottom plate and can withstand this outward. As a result, an enlargement of the existing base area of the room or the building is possible with the outer wall system according to the invention.

According to the invention, a method for installing an outer wall system according to the invention in an existing building is also provided according to claim 13. The method comprises the following steps:

• Attaching bearings for the respective exterior wall to the existing building adjacent to and / or into an existing interior space that can be opened to an existing exterior space, and
• Mounting the movable outer wall in the storage, so that depending on the position of the movable outer wall of the existing interior space can be selectively increased, wherein
• the storage on a subsequently attachable to the building floor plate, ceiling plate and / or side wall and attached to this on the existing building (12) is attached.

The storage is fixed in this case on this base plate, ceiling plate and / or side wall of the existing building.

The method according to the invention can be used on the one hand in new buildings, but it is preferred to use the method for the renovation of existing buildings.

In a further development of the method, the storage together with its associated base plate, ceiling plate and / or side wall are fastened to each other in advance. The resulting plate-shaped units are attached to a house-side floor panel, ceiling plate and / or side wall. The storage can for example already during the production of the bottom plate, the ceiling plate and / or the side wall in this or be attached to this, in order to carry out in a simple manner flush with the bottom plate, the ceiling plate and / or the side wall.

In a preferred embodiment of the method, the bottom plate, the ceiling plate and the side walls are already pre-assembled into a box-like unit. This unit is placed on a house-side floor plate and attached to the building. The exterior wall system is completely pre-assembled, reducing assembly time on the site or on the building.

The box-like unit is preferably placed on an existing balcony or loggia.

In FIG. 1 a flexible outer wall system 10 is shown for a building 12 having an interior space 14 and an accessible exterior space 16 having. The outer space 16 is in this case a balcony, which is accessible from the interior 14 from. The outer wall system 10 has a bottom plate 18, here occupying substantially the complete outline of the outer space 16 and is placed on the house-side bottom plate 19, and two opposite side walls 20, which are each arranged parallel to a side wall 22 of the building 12 at this and fixed , As in FIG. 2 can be seen, the outer wall system 10 also has a ceiling plate 24 which is fixed to the ceiling plate 26 of the building 12.

The outer wall system 10 has a movable outer wall 28, which is composed here of three mutually coupled wall elements 30, 32, 34. As in particular in FIG. 3 can be seen, the reference points FIG. 3 Right wall element 34 here on a door 36 which can open the interior 14 to the exterior 16. The other wall elements 30, 32 each have a window 38, 40. The outer wall system 10 is preceded by a railing 42 on the building 12.

The outer wall system 10 has a bearing 44, here a pair of rails, in which the movable outer wall 28 is slidably mounted in the horizontal direction R (see FIG. 1 ). A first rail 46 of the bearing 44 is provided here in the bottom plate 18, the second rail 48 is disposed in the ceiling plate 24 (see FIG. 2 ). The rails 46 and 48 are each U-shaped and extend with a first portion between the interior space 14 and outside space 16, with a second portion parallel to a side wall 20 of the exterior space 16 and with a third portion along the outside of the balcony.

The mounting 44 of the outer wall system 10 here has an inner closed position 50 and an outer closed position 52, in which the movable outer wall 28 can be locked in each case. The outer wall 28 is held in the bearing 44 so that it can be reversibly moved from one of the closed positions 50, 52 in the other closing position 50, 52. Each of the closing positions 50, 52 is characterized in that the movable outer wall 28 can be locked in the closed position 50, 52 and the inner space 14 can be locked by the outer wall 28 locked in a closed position 50, 52 is separated to an outer area 54 so that the interior 14 is a separate from the outside area 54 air-conditioned room.

By the movable outer wall 28, the size or the base of the air-conditioned interior space 14 is variably changeable. In the outer closed position 52, the outer space 16 is completely in the interior 14 or the air-conditioned space, so that its size or base area is increased. The not usable in bad weather conditions, for example in winter, surface of the outer space 16 can thus at least partially pass into the interior 14 and thus be used even in bad weather conditions.

The operating principle is based on the FIGS. 4 to 6 shown again: In FIG. 4 the movable outer wall 28 is locked in the inner closed position 50, so that the inner space 14 is separated from the outer space 16. The air-conditioned room here corresponds to the volume of the interior 14, the outside space 16 (balcony) is in communication with the outside area 54 (building environment). By provided in the wall element 34 door 36, the exterior space 16 can be entered from the interior 14, so that the exterior space 16 can be used as a balcony, terrace or loggia.

The movable outer wall 28 can along the storage 44 via an in FIG. 6 shown intermediate position 56 are moved into the outer closed position 52. In this intermediate position 56, the interior 14 and the outside space 16 merge into one another, so that a large, continuous space is created, which ensures a pleasant openness of the apartment in the summer.

In the in FIG. 5 illustrated outer closed position 52, the movable outer wall 28 on the outside of the building 12, that is arranged between the outer space 16 and outer area 54. In this closed position, the movable outer wall 28 separates the inner space 14 enlarged by the former outer space 16 from the outer area 54. The air-conditioned room is enlarged. The outer space 16 can thus be used in the outer closed position, for example in winter as a heated living room.

Since the movable outer wall 28 along the storage 44 are easily moved from a closed position 50, 52 in a second closed position 50, 52 can, a rapid adjustment of the closed position of the movable outer wall 28, for example, to changing weather conditions possible. As in the FIGS. 4 to 6 As can be seen, the movable outer wall is displaced along the U-shaped mounting 44, so that the outer space 16 can be fully utilized during the movement process. Furnishings arranged in the outer space 16 need not be removed for a displacement of the movable outer wall 28.

The movable outer wall 28 can be manually moved along the bearing 44, but it is also conceivable that a motor drive not shown here is provided, which moves the movable outer wall 28 along the bearing 44. The motor drive can for this purpose have a control which can be activated manually, time-controlled or by sensors. A time control allows, for example, a time-dependent displacement of the movable outer wall 28 or a time-dependent adjustment of the closed position to the sun.

It is conceivable that the movable outer wall 28 is time-controlled in the summer at noon in the inner closed position 52, so that the incident at a steep angle intense solar radiation heats only the outer space 16, but not the interior 14, whereby a strong heating of the interior 14 is prevented can be. In a shallower sunlight, however, the movable outer wall 28 can be moved to the outer closed position 52, so that the use of solar radiation for heating the interior 14 is possible. In addition, a better illumination of the interior 14 can be achieved by the incident daylight.

However, the control can also be dependent on various sensors, such as light sensors or rain sensors, so that, for example, during rain, the movable outer wall 28 is moved to the outer closed position 52 to protect furnishings that are arranged in the outer space 16.

In the FIGS. 7a to 7c is summarized again the functional principle of the outer wall system 10 according to the invention with reference to the floor plan of the building 12 with the various positions of the movable outer wall 28 shown. In Figure 7a is the moving one Outer wall 28 locked in the inner closed position 50, in which the inner space 14 is separated from the outer space 16. In FIG. 7b the movable outer wall 28 is moved into an intermediate position 56 along a side wall, in the inner space 14 and outer space 16 completely merge into one another. In FIG. 7c the movable outer wall 28 is moved to the outer closed position, in which the outer space 16 merges into the inner space 14.

In addition to the embodiment of the outer wall system 10 according to the invention shown here having two closed positions, embodiments with a plurality of closing positions are also conceivable. In FIG. 8 is schematically shown an outer wall system 10 having a plurality, in this case four closing positions. In addition to the inner closed position 50, the outer wall system 10 shown here has three outer closed positions 52, 58, 60, in which the movable outer wall 28 can be locked in each case, so that the inner space 14 is separated to the outside. In the closed positions 58, 60, only a part of the outer space 16 in each case passes into the inner space 14. The position and the number of closing positions of the outer wall system 10 according to the invention can be varied as desired.

The structure of the outer wall system 10 is in the FIGS. 9a and 9b as well as in the detail views of the storage in FIGS. 10a to 10c shown again. As in the FIG. 9a illustrated sectional view and the in FIG. 9b shown plan view, the ceiling plate 24, the bottom plate 18 and the walls 20 of the outer wall system 10 are each provided with an insulation 62. This is arranged over the entire surface of the bottom plate 18, the ceiling plate 24 and the side walls 20 so that regardless of the selected closing position 50, 52, 58, 60 of the movable outer wall 28 in conjunction with the movable outer wall 28 sufficient insulation of the interior 14 against the outdoor area 54 is ensured.

The detailed views in the FIGS. 10a to 10c show an example of the structure of a possible insulation 62, but it is also possible depending on the climatic conditions and the local building codes, a different structure of the insulation 62.

In FIG. 10a sliding elements 63 are also shown, which are attached to the outer wall 28 and project into the rails.

In addition, supply lines can be provided in the side walls 20, the base plate 18 and the ceiling plate 24, for example for connecting electrical appliances, heating or cooling elements. It is also conceivable that heating or cooling elements, lighting systems, ventilation systems or electrical connection options are integrated into the outer wall system 10.

On the bottom plate 18 of the outer wall system 10 is also a in the FIGS. 10b and 10c illustrated water drain 64 is provided. This allows for the locking of the movable outer wall 28 in the inner closed position 50 a drain of rainwater from the outer space 16. As in FIG. 10c can be seen, the movable outer wall 28 is formed so that it closes the water outlet 64 at a lock in the outer closed position 52, 58, 60.

The FIGS. 11a to 11c again show a perspective view of a building section with an outer wall system 10 according to the invention in different closing positions of the movable outer wall 28. In FIG. 11a is the movable outer wall 28 in the inner closed position 50, in FIG. 11b in an intermediate position 56 and in FIG. 11c in the outer closing position 52.

As in the FIGS. 11a to 11c can be seen, the bottom plate 18, the ceiling plate 24 and the side walls 20 of the outer wall system 10 form a box-like unit. This is self-supporting in the present case, so that the outer wall system 10 must be placed only on the bottom plate 19 of the building 12 and attached to the building 12. The outer wall system 10 shown here can thus be completely pre-assembled and used as a preassembled box-like unit in the building 12. The exterior wall system 10 can thus be preassembled, for example, in the factory and delivered to the construction site as a mounted unit, so that it only has to be used on the building 12 or in the room. A complex production of the outer wall system on the construction site or on the building 12 is therefore not necessary. The exterior wall system 10 is ideal for the renovation of prefabricated housing or large residential buildings, because it will be without large Structural effort increases the living space and improves the thermal insulation.

The outer wall system 10 is so far inserted into the building 12 in the embodiment shown here that the outer wall system 10 is largely flush with the outside of the bottom plate 19 of the building 12.

As an example in the FIGS. 12a to 12c illustrated, but it is also conceivable that the outer wall system 10 projects over the outer skin of the building 12 or the bottom plate 19 to the outside, so that an enlargement of the base of the building 12 is possible by the exterior wall system 10 according to the invention.

The outer wall system 10 may also be mounted completely on the outside of a building wall of the building 12. In this case, the outer wall system 10 is placed, for example, on supports provided on the outside or mounted on supports which are fastened to the building wall. Depending on the installation conditions, the outer wall system 10 may be fastened to the supports with the ceiling panel 24, the floor panel 18 and / or the side walls 20, so that the outer wall system 10 is optionally mounted on the supports or suspended thereon. Deviating from this, other mounting options on the building wall are conceivable.

The FIGS. 13 to 15 each show various possible arrangements of the outer wall system 10 on a building 12. In FIG. 13 is the balcony / loggia completely covered and flush with the outer skin of the building 12, while in FIG. 14 the balcony is completely in front of the outer wall of the building 12. In this case, the outer wall system 10 may be placed on a building the balcony upstream, but it is also conceivable that the outer wall system is completely attached to the outside of the building wall. In FIG. 15 the balcony / loggia is partially moved into the building 12. The exterior wall system covers the entire balcony / loggia.

Notwithstanding the embodiments shown so far, in which the outer wall system 10 forms a self-supporting structure or represents a preassembled unit, which can be mounted as a whole on a building 12, Embodiments without side walls 20 or ceiling plate 24, bottom plate 18 are conceivable.

If, as previously mentioned, the outer wall system is placed as a completely pre-assembled box or box-shaped unit on the building-side base plate 19, an extremely fast on-site assembly can be realized.

Alternatively, for example, to avoid the use of a crane, the bottom plate 18, ceiling plate 24 and side walls 20 as pre-assembled in itself, separate units prefabricated only be assembled on the building. Furthermore, these panels or walls could be assembled from individual elements (for example 1 m wide elements) on site.

The plates and walls are for example hollow body with an insulation in the interior, wherein stiffeners in the form of trapezoidal elements or the like may be provided in the interior. Furthermore, it is possible on the outside, under certain circumstances, to pre-assemble an insulation immediately.

In addition to the embodiments shown so far, it is also conceivable that the outer wall system 10 has only a bottom plate 18 and a cover plate 24 in which the bearing 44 of the movable outer wall 28 is arranged. The ceiling panel 24 may be anchored in the ceiling 26 of the building 12 so that no supporting side walls 20 are necessary. By the bottom plate 18 and the ceiling plate 24, for example, unevenness of the building ceiling or the building floor can be compensated.

In the FIG. 16 illustrated embodiment has the special feature that the outer wall system 10 has no bottom plate 18 and no ceiling plate 24. The rails 46, 48 are used here directly in the bottom plate 19 and the ceiling plate 26 of the building 12 and close flush with these. On the bottom plate 19 and the ceiling plate 26, an insulation 62 is provided in each case to ensure sufficient thermal insulation. This embodiment is preferably suitable for new buildings, in which the rails 46, 48 in the manufacture of the ceiling plate 26 and the bottom plate 19 can be secured therein.

The following are in the FIGS. 17 to 21 exemplified further embodiments of the outer wall system 10 according to the invention. Regardless of the shape of the outer wall system 10 in the FIGS. 17 to 21 all embodiments have an inner closed position 50 and an outer closed position 52, in each of which the movable outer wall 28 separates the interior 14 to the outside. In addition, in the outer closing position 52 at least a part of the outer space 16 in each case passes into the inner space 14. Although the embodiments shown here deviate from the illustrations shown so far, the reference numbers used hitherto are retained for all embodiments. In the following, only the differences of the various embodiments will be discussed. The outer wall system 10 is shown with the movable outer wall 28 in an outer closed position 52 (a) and in an inner closed position 50 (b), respectively.

FIG. 17 shows the embodiment shown so far with a rectangular outer wall system 10, which is partially inserted into the building 12.

In FIG. 18 the outer wall system 10 is round in plan. The movable outer wall 28 is formed here as a half-cylinder, and the bearing 44 extends on a circular path. By this design of the outer wall system 10, the movable outer wall 28 can be integrally formed without joints.

Instead of the round outline is also a polygonal floor plan, for example, the in FIG. 19 shown octagonal floor plan possible. The bearing 44 extends here in the form of an octagon, the movable outer wall 28 has a plurality of wall elements 30, 32, 34 which are mutually movable.

This in FIG. 20 illustrated outer wall system 10 includes a triangular outer space, wherein the movable outer wall 28 extends over the entire leg of the triangle. The inner closed position 50 forms a leg of the triangle, the outer closing positions 52 a second leg. The third leg of the triangle is formed by a side wall 22. The bearing 44 extends here along the side wall 22, but it is also conceivable that the bearing 44 extends over the top of the triangle.

This in FIG. 21 illustrated outer wall system 10 includes a rectangular exterior space. Notwithstanding the embodiments shown so far, two movable outer walls 28 are provided which define two adjacent sides of the rectangle.

In addition to the embodiments shown so far, other embodiments of the outer wall system 10 according to the invention and the movable outer wall 28 are conceivable. The movable outer wall 28 may be made in one piece or composed of a plurality of wall elements 30, 32, 34. These wall elements 30, 32, 34 can be movably coupled to one another and / or to one another. It is also conceivable that the wall elements 30, 32, 34 can be separated from each other, so that they are individually displaceable along the bearing 44.

The bearing 44 may be formed arbitrarily depending on the embodiment and design of the outer wall system. In the FIGS. 22 to 24 By way of example, various embodiments of the bearing 44 of the movable outer wall 28 are shown. In each of these, the movable outer wall 28 is shown in the outer closing position 52, see Figure (a), in an intermediate position 56, see Figure (b), and in an inner closing position 50, see Figure (c).

In FIG. 22 For example, the bow or U-shaped bearing 44 is shown in which a three-part movable outer wall 28 is mounted. In the intermediate position 56, the movable outer wall 28 can be fully applied to the side wall 22 so that the inner space 14 and the outer space 16 completely merge into one another.

In the FIG. 23 shown embodiment of the bearing 44 has at the corners of the bearing 44 each have a switch 65. As a result of the shape of the rails 46, 48 selected here, the movable outer wall 28 can not be moved in an intermediate position when moving from the closed position 50, 52 into the respective other closed position 50, 52, in which it rests completely against the side wall 22. In another position of the switch 65, however, the movable outer wall 28 is moved to an intermediate position along the side wall 22, in which the movable outer wall 28 rests completely against the side wall 22.

In FIG. 24 Also shown is a movable outer wall 28 consisting of two wall elements 30, 32. The wall elements 30, 32 can also be separated from each other and each have a U-shaped mounting 44 along the two side walls 22.

Instead of a displacement transversely to the extension direction of the movable outer wall 28, it is also conceivable to move the movable outer wall 28 perpendicular to its extension direction, ie in the vertical direction. As in the sectional views in the FIGS. 25 and 26 can be seen, the rails 46, 48 of the bearing 44 may each be disposed on a side wall 22 and extend from the outer closed position 52 on the ceiling plate 24 of the outer wall system 10 to the inner closed position 50. In the in FIG. 25 illustrated embodiment, the rails 46, 48 on the ceiling plate 24 an additional switch 66, over which the movable outer wall 28 can be moved in an intermediate position 56 along the ceiling plate 24.

Deviating from the rails 46, 48 in the in FIG. 26 shown embodiment formed so that the movable outer wall 28 when moving from the outer closed position 52 into the inner closed position 50 completely abuts in an intermediate position 56 on the ceiling plate 24.

The outer wall system 10 according to the invention is suitable both for installation in new buildings as well as for installation in existing, older buildings, for example, for refurbishment or modernization of the building. By a corresponding design of the movable outer wall 28 and the externally visible elements of the outer wall system 10 also a subsequent change or design of the facade of the building 12 is also possible.

If the required room heights or the required load capacity of the ceiling or the floor plate of the building 12 is present, any arrangement of the outer wall system 10 in a building 12 is conceivable. In the FIGS. 27a to 27f By way of example, various arrangements of the outer wall system 10 in a building 12 are shown. In the embodiments illustrated here, the outer wall system 10 is shown in each case flush with the outer skin of the building 12. It is obvious, however, that the outer wall system 10 according to the invention is independent from the position in the building 12 may be formed over the outer shell of the building 12 cantilevered.

In Figure 27a For example, the exterior wall system 10 is located on the ground floor of the building 12. The exterior space 16 may here, for example, pass into a terrace area located in front of the building or, in the case of a cantilevered shape of the exterior wall system 10, form part of the terrace. In Figure 27b the outside wall system 10 is arranged in an upper floor of the building 12. In the Figures 27c and 27d the outer wall system 10 is arranged in each case in the attic of the building 12. In the in Figure 27c illustrated embodiment here is a part of the building roof removed or replaced by the ceiling plate 24 of the outer wall system 10.

Im in Figure 27e illustrated embodiment, an intermediate ceiling of the building 12 is also removed, so that the outer wall system 10 over several, here two floors runs. This in Figure 27f illustrated embodiment, however, is aligned towards a courtyard.
