Description

[0001] Buildings and flexible interior wall systems for buildings

[0002] The present invention relates to a building and a flexible interior wall system for buildings.

[0003] The requirements for the heating energy demand of buildings, and therefore for thermal insulation, have increased significantly in recent years. These increased requirements are in conflict with the desire for low construction costs. Consequently, there is a need for buildings that can be constructed cost-effectively while still meeting the stringent requirements for heating energy demand and thus thermal insulation.

[0004] The present invention solves this problem by means of a building comprising a base slab, an exterior wall, and a roof structure arranged on the exterior wall. The base slab has perimeter insulation extending around its perimeter. The exterior wall comprises wall modules and vertical supports arranged on the base slab. Each wall module has an insulating layer extending through it. The vertical supports are arranged inside the exterior wall and are surrounded by the wall modules, particularly on all sides. The roof structure comprises roof trusses and roof modules arranged on the trusses. The roof modules have an insulating layer extending through each module. This insulating layer forms connection areas through which the roof modules are connected over their entire surface to adjacent roof modules and / or wall modules of the exterior wall.The load of the roof structure, as well as loads acting on the roof structure such as wind and / or snow loads, are transferred via the building's outer wall, in particular the vertical supports of the building's outer wall, into the base plate.

[0005] The edge insulation of the floor slab ensures all-around insulation of the floor slab.

[0006] In particular, the insulation layers of the wall modules form connection areas through which the insulation layers of the wall modules are connected to the insulation layers of adjacent wall modules and / or the perimeter insulation of the floor slab and / or the insulation layer of a roof module located adjacent to the wall module. The insulation layers of the wall modules thus form an insulation layer extending through the building's exterior wall and around the building.

[0007] The roof module insulation layers form a roof insulation layer spanning the roof structure and the building.

[0008] The roof insulation layer transitions into the insulation layer of the building's exterior wall at the corresponding contact points between the roof modules and the wall modules. Similarly, the insulation layer of the building's exterior wall transitions into the edge insulation of the foundation slab at the corresponding contact points between the wall modules and the foundation slab.

[0009] The insulation of the foundation slab perimeter, the insulation layers of the wall modules, and the insulation layers of the roof modules come into contact with each other during the building assembly, thus forming at least a continuous thermal insulation envelope for the building. The insulation layers of the wall modules contact the insulation of the foundation slab perimeter and the insulation layers of the roof modules. This allows such a building to be easily constructed with a thermal bridge-free thermal insulation envelope.

[0010] The thermal insulation envelope can be completed by doors and / or windows installed in the building's outer wall and / or roof structure.

[0011] Preferably, the wall modules are arranged in such a way that they extend between two adjacent vertical supports.

[0012] Preferably, at least some of the wall modules have an inner side and an outer side opposite the inner side, a top side and a bottom side opposite the top side, as well as a first end face and a second end face opposite the first end face. Such wall modules have a roughly cuboid shape. The wall modules each comprise a layer of insulation material that extends parallel to the inner and outer sides through the wall module. With such wall modules, a building with a continuous thermal insulation envelope can be easily achieved.

[0013] These wall modules preferably each have a first connecting section on their first end face. On their second end face, the wall modules have a second connecting section. The first and second connecting sections are designed to correspond to each other, so that a wall module with its first connecting section can be connected to the second connecting section of another wall module.

[0014] The first and second connecting sections can be designed such that the wall module and the subsequent wall module are positively connected to each other via these sections. Alternatively or additionally, the wall module and the subsequent wall module can also be connected by friction and / or material bonding. The wall modules can be screwed and / or glued together. The wall modules can also be equipped with magnets and / or magnetizable elements, so that they are held together by magnetic forces. Alternatively or additionally, the wall modules can be pressed against each other at the connecting sections and fixed to a support structure, in particular by screws. The wall modules then touch at the connecting sections, but are not necessarily connected to each other beyond this point.The choice of means by which the first connecting section and the second connecting section are connected to each other, or by which the wall modules are fixed to each other, can be made taking into account cost aspects depending on the stability, tightness and / or load-bearing capacity of the building's outer wall or the building itself.

[0015] Preferably, the first connecting section and the second connecting section are designed in such a way that they form a cavity between them.

[0016] In particular, the cavity formed between the wall modules has a completely closed perimeter when viewed in a cross-section parallel to the top surface. One of the vertical supports of the building's exterior wall is located within this cavity. Two adjacent wall modules can easily accommodate a vertical support between them.

[0017] The building's exterior wall comprises a plurality of vertically arranged columns. Preferably, each wall module is positioned so that it extends between two adjacent columns. Particularly preferably, two wall modules arranged adjacent to a vertical column accommodate the vertical column in the cavity formed between their abutting connecting sections. In this way, a building's exterior wall and building can be obtained that are free of thermal bridges. At the very least, the risk of thermal bridges in such a building is reduced. The wall modules can be prefabricated cost-effectively and are easy to handle. This reduces the costs for constructing the building's exterior wall and thus the building itself.

[0018] Wall modules, designed as door or window modules, can be integrated into the building's exterior walls. These are used in the area of ​​door or window openings. Naturally, no vertical supports are located within the door or window opening itself. The thermal insulation envelope is typically completed in the area of ​​door or window openings by the doors or windows installed within them.

[0019] In particular, door or window modules are regularly arranged in such a way that they do not have any vertical supports between them.

[0020] In the area of ​​corners of the building's exterior wall, special corner wall modules are typically installed. On a corner wall module, a second connection point can be located not on the second end face, but on the inside of the corner wall module. Alternatively, a first connection point can be located not on the first end face, but on the inside of the corner wall module.

[0021] Buildings with rectangular floor plans are preferred. Buildings with rectangular floor plans have a particularly favorable surface area to volume ratio. However, buildings with non-rectangular floor plans, such as L-shaped floor plans, can also be constructed. In this case, corner wall modules are used, which have the first or second connection point on the outside of the module instead of on the respective end face.

[0022] The exterior wall of such a building can be erected particularly easily. First, a vertical support is mounted to the foundation slab. Then, a wall module is positioned against the vertical support so that the support is aligned with the second connection point of the wall module. If the second connection point is a groove, the vertical support fits into the groove of the wall module. The next vertical support can then be positioned against the foundation slab in front of the second connection point of the wall module. The wall module extends between the two vertical supports. The next wall module can then be positioned against the next vertical support so that the support is aligned with the groove of the next wall module. This process can be continued until the exterior wall of the building is almost completely erected.The last wall module can then be inserted from above between the two adjacent wall modules or the two adjacent vertical supports.

[0023] In particular, the cavity has a depth of 50 mm to 150 mm, preferably 100 mm. The depth of the cavity is the distance between the parts of the wall modules arranged adjacent to each other that define the cavity, in a direction from the first end face to the second end face.

[0024] Furthermore, the cavity has a width of between 50 mm and 150 mm, preferably 100 mm. The width of the cavity is the distance between the parts of the adjacent wall modules that define the cavity, measured from the inside to the outside. The cavity for receiving a vertical support then has dimensions between 50 mm x 50 mm and 150 mm x 150 mm, preferably 100 mm x 100 mm. Preferably, but not necessarily, the cavity for receiving a vertical support has a square cross-section.

[0025] Preferably, the insulation layer extending parallel to the inside and outside through the wall module forms at least the top and bottom of the wall module, with the insulation layer forming a connecting tongue and groove on the bottom. The floor slab edge insulation has a connecting groove into which the connecting tongue and groove arranged on the underside of the wall module is inserted. In an alternatively preferred embodiment, the floor slab edge insulation forms a connecting tongue and groove, and the underside of the wall module has a connecting groove. The connecting tongue and groove of the floor slab edge insulation is inserted into the connecting groove on the underside of the wall module. By using a connecting tongue and groove formed by the floor slab edge insulation, which is connected to a corresponding connecting groove or groove, the system is designed to be easily connected to the wall module.By using a tongue and groove joint on the underside of the wall module, a thermal bridge-free, or at least low-thermal-bridge, connection between the floor slab edge insulation and the wall module is easily achieved in this area. This allows the building to be fitted with a thermal insulation envelope with low or no thermal bridges in a particularly simple manner.

[0026] Preferably, the insulation layer forms at least part of the first and second end faces. The insulation layer thus extends through the entire wall module. In particular, the insulation layer forms at least part of the first and second connection areas.

[0027] Furthermore, and particularly preferably, the first and second connection areas are formed entirely by the insulation layer. If a wall module constructed in this way is connected to a similar, adjacent wall module by having the first connection area of ​​one wall module contact the second connection area of ​​another, adjacent wall module, then the insulation layer of one wall module is also in contact with the insulation layer of the other wall module. In this way, a continuous insulation layer across the individual wall modules is easily achieved. The building's exterior wall can be easily constructed with a largely, preferably completely, avoidance of thermal bridges. The building's thermal envelope can be easily maintained.Preferably, the first connection area is designed as a tongue and groove, and the second connection area as a groove for receiving a tongue and groove of another wall module. The wall module is thus designed such that two adjacent wall modules are connected to each other via the tongue and groove of one wall module and the groove of the other, similar to a tongue-and-groove connection. The tongue of one wall module is inserted into the groove of the other wall module. A tongue and groove is understood to be a tongue integrally formed with the wall module. Connection areas designed in this way allow two adjacent wall modules to be fixed relative to each other particularly easily. The tongue and groove form a positive-locking connection. Additionally, the wall modules can be bonded together in the connection area, in particular by adhesive bonding. The wall modules can also be bonded to a support structure.Alternatively or additionally, the wall modules can be screwed together, particularly to each other and / or to the support structure. Alternatively or additionally, the wall modules can also be magnetically attached to each other and / or to the support structure using magnetic elements.

[0028] The depth of the groove is significantly greater than the depth of the tongue and groove. When two adjacent wall modules are connected by inserting the tongue and groove of one module into the groove of the other, a cavity remains between the modules in the connection area. This cavity is bounded by the groove of one module and the tongue and groove of the other. This space is dimensioned to accommodate a vertical support column of a building. Wall modules designed in this way can be easily joined together.

[0029] Preferably, the insulation layer forms an additional tongue and groove on the end faces, the depth of which corresponds approximately to the depth of the groove. When adjacent wall modules are joined, two tongue-and-groove connections are thus created. The tongue-and-groove connection forms the cavity described above, through which two adjacent wall modules can accommodate a vertical support between them. The additional tongue and groove form a substantially cavity-free connection. Constructing a building wall with largely, preferably completely, avoiding thermal bridges is further simplified with such wall modules.

[0030] Particularly preferably, the additional tongue and groove are arranged on the first end face and the additional groove on the second end face. Both tongues and both splines are thus located on the same end face. This simplifies the handling of the corresponding wall modules. However, it is also conceivable to provide the tongue and groove on the first end face and the groove and tongue and groove on the second end face. Furthermore, and particularly preferably, the additional tongue and groove are arranged closer to the outside than the tongue and groove alone. The additional tongue and groove form a particularly good connection between the insulation layers of two adjacent wall modules. This ensures that this particularly good connection between the insulation layers of the adjacent wall modules is located on the outside, in front of the cavity for accommodating a vertical support between the wall modules.A vertical support positioned in the area between the tongue and groove is thus particularly well insulated from the outside climate. This reduces the risk of thermal bridges extending to such a vertical support, which could lead to increased heat loss due to conduction along the support.

[0031] Preferably, the insulation layer has a connecting groove on its upper surface or forms a connecting tongue and groove on its upper surface. The connecting groove can interact with a corresponding connecting tongue and groove, or vice versa, in an insulation layer positioned above a wall module. This allows for a simple, thermal bridge-free connection between the wall module and the insulation layer positioned above it. At the very least, the risk of thermal bridges is significantly reduced with this design.

[0032] The insulation layer to be placed below or above the wall module can be an insulation layer of another wall module. However, the lower insulation layer will most likely be an insulation layer of the floor slab perimeter insulation, and the upper insulation layer will be the insulation layer of a roof module. In this case, the wall modules are designed to extend over the entire height of the building's exterior wall.

[0033] Preferably, the wall modules are designed such that the distance between the underside and top of the wall module corresponds to the height of the building's exterior wall. This prevents the need to stack multiple wall modules on top of each other when constructing the exterior wall. Any thermal bridges at such joints between two stacked wall modules are thus eliminated. Constructing a thermal bridge-free, or at least thermally bridge-free, exterior wall using these wall modules is therefore simplified.

[0034] Preferably, the insulation layer has a support recess on its upper surface, spaced apart from the outer surface. A support beam can be inserted into this support recess. Particularly preferably, the support recess is arranged so that such a beam can rest on the vertical supports located in the area bounded by the tongue and groove of two adjacent wall modules. Such a beam can preferably extend through the support recesses of several wall modules arranged side by side. A wall module with such a support recess makes it easy to arrange such a beam with thermal insulation. Constructing a thermal bridge-free or at least low-thermal-bridge building exterior wall using such wall modules is facilitated.

[0035] Preferably, at least some of the wall modules have recesses for utility lines on their inner surface. These recesses allow for the easy routing of supply lines, water and / or wastewater pipes, and heating system pipes. This simplifies the construction of the building using these wall modules.

[0036] Preferably, the insulation layer consists of extruded polystyrene (XPS), polyurethane (PUR), or polyisocyanurate (PIR). Insulation layers made of extruded polystyrene (XPS), polyurethane (PUR), or polyisocyanurate (PIR) can be easily manufactured to form a tongue and groove joint that is robust and easy to join. Using these insulation materials, a load-bearing wall module can be easily produced. Such wall modules are particularly easy to handle.

[0037] A wall module is preferably made of one of the aforementioned materials. Such a wall module then consists solely of the insulation layer. A wall module consisting exclusively of the insulation layer is particularly lightweight and easy to handle and install. It can subsequently be clad on the outside with plaster, brick, wood, or other facade solutions. On the inside, such a wall module can also be finished as desired with, for example, plasterboard, wood fiberboard, or other interior cladding systems.

[0038] Preferably, the insulating layer material has a compressive strength of at least 100 kPa. Such a wall module has sufficient load-bearing capacity for its intended use, particularly even if the wall module consists solely of the insulating layer.

[0039] Preferably, the insulation layer is between 300 mm and 600 mm thick. In particular, the insulation layer has a thickness of 500 mm. This thickness is measured vertically between the inside and outside of the wall module. A wall module with a correspondingly high insulation thickness has a low thermal transmittance coefficient. The requirements for low energy consumption can be easily met with such wall modules.

[0040] Preferably, the base slab has column anchors into which the vertical columns are inserted and secured. These column anchors are cast into the base slab. The use of such column anchors allows for particularly simple construction of the building. A vertical column can be easily inserted into a column anchor using simple tools or even without tools. Similarly, the placement of the wall module on the vertical column can preferably be done with simple tools or without tools.

[0041] Preferably, the support anchors and the vertical supports are formed by hollow profile elements. The internal dimensions of a hollow profile forming a support anchor are selected to correspond approximately to the external dimensions of a hollow profile forming a vertical support. Vertical supports designed as hollow profiles are particularly lightweight and can therefore be easily inserted into the support anchors.

[0042] The hollow profile elements can have a round cross-section.

[0043] Preferably, the hollow profile elements have a rectangular, in particular square, cross-section.

[0044] A vertical support can be formed by a hollow profile with a square cross-section of 100 mm x 100 mm and a wall thickness of 50 mm. The support anchor must then be designed to accommodate such a vertical support.

[0045] Particularly preferably, the column anchor has at least one inwardly projecting locking element. In particular, the locking element is tongue-shaped with a free end, this free end pointing in the direction of insertion of a vertical column into the column anchor. The vertical column has at least one locking recess corresponding to and cooperating with the locking element. The locking element is inserted into the locking recess. A vertical column can be easily inserted into the column anchor and is secured against removal by the locking element inserted into the locking recess. The vertical columns can be easily installed by inserting them into the column anchor.

[0046] Furthermore, the column anchor preferably has two opposing locking elements. The vertical column has corresponding locking recesses. Symmetrically arranged locking elements and recesses facilitate the insertion of the vertical columns into the column anchors, as there are multiple positions in which the locking elements and recesses interact. This simplifies the alignment of the vertical column within the column anchor.

[0047] Preferably, the roof structure of the building comprises a roof truss frame formed from beams arranged on the vertical supports, with the roof trusses being arranged on the roof truss frame. The roof modules are arranged on the roof trusses, each having a top surface and a bottom surface opposite the top surface. The bottom surface of the roof modules is provided with recesses for roof trusses in which roof trusses are arranged. The insulation layer of the roof module extends through the module parallel to both the top and bottom surfaces.

[0048] By using a roof truss frame with roof beams, the building can easily be constructed with a self-supporting roof structure. The roof structure rests on the vertical supports of the building's exterior walls via the roof truss frame. The building can be designed in such a way that no additional supports are required inside to support the roof structure. This allows for a particularly flexible floor plan within the building. Such a building can be maintained very easily and cost-effectively.

[0049] Preferably, the connection areas, through which adjacent roof modules are joined, extend horizontally. More preferably, these connection areas have an S-shaped cross-section. Horizontally extending connection areas allow the roof modules to be easily mounted onto the roof support frame or the roof beams attached to it. The horizontal extension of the connection areas makes it possible to place a roof module from above next to an already mounted roof module, with the connection areas of the two adjacent roof modules interlocking. An S-shaped cross-section secures the roof modules against displacement in the horizontal plane. At the same time, an S-shaped connection area can be manufactured with a high degree of tightness, making it particularly easy to achieve.

[0050] Preferably, the roof module insulation layer consists of extruded polystyrene (XPS), polyurethane (PUR), or polyisocyanurate (PIR). Roof module insulation layers made of these materials can be easily manufactured to form a tongue and groove joint, which is robust and easy to join. Using these roof module insulation materials, a load-bearing roof module can be easily produced. Such roof modules are particularly easy to handle.

[0051] A roof module is preferably made of one of the aforementioned materials. Such a roof module then consists solely of the roof module insulation layer. A roof module consisting exclusively of the roof module insulation layer is particularly lightweight and easy to handle and install.

[0052] Preferably, the material of the roof module insulation layer has a compressive strength of at least 100 kPa. Such a roof module possesses sufficient load-bearing capacity for its intended use, particularly even when the roof module consists solely of the roof module insulation layer. The invention further relates to a flexible interior wall system. This flexible interior wall system comprises interior wall modules that are provided with rollers on at least one underside, allowing the modules to be moved. Furthermore, each interior wall module has at least one fixing device by which the modules can be clamped between the floor and ceiling of a building. With such a flexible interior wall system, the modules can be easily released from the fixing device and moved to another location.The interior layout of the building can thus be flexibly adapted to individual needs in a simple and cost-effective manner.

[0053] Interior wall modules are particularly preferred when equipped with rollers on their upper surface. Such modules can be moved very easily within the building once the fixing devices are released.

[0054] The fixing devices can be mechanically operated, for example, via a threaded connection that allows the interior wall module to be extended and retracted between a floor and ceiling. Such a fixing device can be operated, for example, with a screwdriver or, in particular, an electric hand drill or cordless screwdriver. Preferably, the interior wall modules are provided with a layer of insulation, similar to the wall modules. These types of interior wall modules are particularly lightweight and easy to move. Nevertheless, they offer a high level of insulation, which also provides effective sound insulation. The interior wall modules can isolate noise from a first room separated by the interior wall modules within the building from another room.

[0055] Preferably, the interior wall modules consist exclusively of an insulating layer made of extruded polystyrene (XPS), polyurethane (PUR) or polyisocyanurate (PIR).

[0056] Preferably, the compressive strength of the insulation layer is at least 100 kPa.

[0057] These types of interior wall modules can be manufactured with a significantly thinner layer of insulation than standard wall modules. The insulation thickness of interior wall modules can range from 100 mm to 300 mm. Using interior wall modules with thinner insulation reduces the space required for the modules. This means less valuable interior space is lost when installing them. At the same time, the insulation performance of the flexible interior wall system made from these modules is maintained. The interior wall modules can be equipped with cutouts for utility lines.

[0074] Parts that function identically or similarly are provided with identical reference numerals, where appropriate. Individual technical features of the embodiments described below can be combined with the features of claim 1 and with the features of individual embodiments described above to form articles according to the invention.

[0075] Fig. 1 shows a wall module 2 with an inner surface 4 and an outer surface 6 opposite the inner surface 4. The outer surface 6 is not visible in the illustration in Fig. 1. The wall module 2 also has a top surface 8 and a bottom surface 10, which is not visible in Fig. 1. The bottom surface 10 is opposite the top surface 8. Furthermore, the wall module 2 has a first end face 12 and a second end face 14 opposite the first end face 12. In the illustrated embodiment, the first connecting section is formed by a tongue and groove 16. The second connecting section is formed by a groove 20.

[0076] The first connecting section and the second connecting section can also be designed differently, provided that the two connecting sections can form a cavity between them which can accommodate a vertical support 56.

[0077] The tongue 16, together with another tongue 18, is arranged on the first end face 12. The groove 20 is formed in the wall module 2 on the second end face 14. Furthermore, another groove 22, which is barely visible in Fig. 1, is arranged on the second end face 14. Supply line recesses 24 are visible on the inside 4. Supply lines can be routed along the wall module 2 in a particularly simple manner via the supply line recesses 24.

[0078] The wall module 2 according to Fig. 1 consists entirely of an insulating material.

[0079] In particular, extruded polystyrene (XPS), polyurethane (PUR), polyisocyanurate (PIR), or another insulating material with a compressive strength of at least 100 kPa is used as the insulating material. The entire wall module 2 thus forms an insulating layer 26 extending between the inner surface 4 and the outer surface 6. Such a wall module 2 has a comparatively low specific weight and is easy to handle. By using extruded polystyrene (XPS), polyurethane (PUR), or polyisocyanurate (PIR), a wall module 2 consisting solely of the insulating layer 26 can be easily obtained. The corresponding insulating materials can be readily produced with the necessary strength.

[0080] The tongue 16 of the wall module 2 is designed to be inserted into the groove 20 of another, identical wall module. The dimensions of the tongue 16 perpendicular to the inner side 4 or the outer side 6 correspond approximately to the dimensions of the groove 20 perpendicular to the inner side 4 or the outer side 6. However, the depth of the groove 20, the extent of the groove 20 in one direction from the second end face 14 to the first end face 12, is significantly greater than the corresponding depth of the tongue 18, the dimension of the tongue 18 in the same direction between the second end face 14 and the first end face 12. When the tongue 16 is arranged in a groove 20 of another, identical wall module 2, a cavity remains between the groove 20 and the tongue 16.

[0081] On its upper surface 8, the wall module 2 has a connecting tongue and groove 28. This connecting tongue and groove 28 lies in the same plane as the other tongue and groove 18.

[0082] Fig. 2 shows a top view of the upper surface 8 of the wall module 2 according to Fig. 1. It can be seen that the additional tongue 18 and the additional groove 22 are arranged closer to the outer surface 6 of the wall module 2 than the tongue 16 and the groove 20. Furthermore, it can be seen that the additional tongue 18 and the additional groove 22 are designed such that the additional tongue 18 substantially completely fills the additional groove 22 when the additional tongue 18 is inserted into an additional groove 22 of another, similar wall module 2.

[0083] Fig. 2 can also be seen that the tongue 16 does not completely fill the groove 20 when it is inserted into the groove 20 of another, similar wall module 2.

[0084] Fig. 3 shows a side view of the wall module 2 according to Fig. 1. Fig. 3 shows a view of the first end face 12. It can be seen that the wall module 2 has a support recess 30 on its upper surface 8. This support recess 30 is located on the side of the wall module 2 facing away from the outer surface 6. On its lower surface 10, the wall module 2 has a connecting groove 32. Fig. 4 shows a building 34 according to the invention with an exterior wall 36, which was constructed using wall modules 2. In addition to the wall modules 2, corner wall modules 38 and door and window modules 40, 42 were also used for the exterior wall 36. The building 34 has a base slab 44, which is provided with edge insulation 46.

[0085] Furthermore, building 34 is equipped with a roof structure 48. The roof structure 48 comprises roof modules 50 and roof beams 52 on which the roof modules 50 are arranged.

[0086] The floor slab edge insulation 46, the wall modules 2, corner modules 38 and door and window modules 40, 42 of the building exterior wall 36 as well as the roof modules 50 of the roof construction 48 form a continuous thermal insulation envelope of the building 34.

[0087] The thermal insulation envelope is supplemented by doors and windows in the area of ​​door and window modules 40, 42.

[0088] Fig. 5 shows an exploded view of building 34 according to Fig. 4. In Fig. 5, the base slab 44 with the base slab edge insulation 46 is clearly visible. Column anchors 54 are arranged in the base slab 44. One of these column anchors 54 is shown in Fig. 5 at a distance from the base slab 44. Vertical columns 56 are inserted into the column anchors 54. The vertical columns 56 and the wall modules 2 are arranged such that each wall module 2 extends between two adjacent vertical columns 56. One of the vertical columns 56 is inserted into the groove 20 of the wall module 2. No vertical columns 56 are arranged in the area of ​​the door and window modules 40, 42.

[0089] A roof support frame 58 is arranged on the vertical supports 56. The roof support frame 58 is formed from beams arranged on the vertical supports. The roof beams 52 are arranged on the roof support frame 58.

[0090] Fig. 6 shows a wall module 2 and a corner wall module 38. The corner wall module 38 is similar in design to the wall module 2. It differs from the wall module in that the groove 20 and the further groove 22 are not located on the second end face 14 but on the inner side 4 of the corner wall module 38. The corner wall module 38 can thus be joined with its inner side 4 to the first end face 12 of a wall module 2. This allows a 90-degree angle to be achieved between the wall module 2 and the corner wall module 38. The supply line recesses 24 of the corner wall module 38 are adapted accordingly so that they end before the groove 20 and are aligned with the supply line recesses 24 of the wall module 2 when the corner wall module 38 is connected to the wall module 2.

[0091] Fig. 7 shows door and window modules 40, 42. The door modules 40 extend over the entire height of the building's exterior wall 36. Each door module 40 has a door opening on its facing sides. Window modules 42 are arranged between the door modules 40, extending above an opening formed by the door and window modules 40, 42 for one or more windows. Door and window modules 40, 42 can also be provided with service openings 24. Each module has a tongue 16 and a second tongue 18 on a first end face 12, and a groove 20 and a second groove 22 on a second end face 14, which interact with the tongue 16 and the second tongue 18 of another module. However, no vertical supports 56 are arranged between the door and window modules 40, 42.The recess for doors and / or windows, limited by door and window modules 40, 42, regularly remains free of vertical supports 56.

[0092] Fig. 8 shows a section of the exploded view from Fig. 5 in the area of ​​the base plate 44. The column anchors 54, which are embedded in the base plate 44, are visible. One of the column anchors 54 is shown in the exploded view in Fig. 8. Vertical columns 56, which can be arranged in the column anchors 54 of the base plate 44, are also shown. Furthermore, Fig. 8 shows that the base plate edge insulation 64 has a connecting tongue and groove 28. This connecting tongue and groove 28 serves to interact with a connecting groove 32 on the underside 10 of the wall module 2. This is shown again in Fig. 9.

[0093] Fig. 10 shows a cross-section through a column anchor 54 with a vertical column 56 arranged therein. It can be seen that the column anchor 54 forms locking elements 60 and the vertical column 56 is provided with locking recesses 62. In the illustrated embodiment, the locking elements 60 are tongue-shaped and have a free end. In the assembled state, one of the locking elements 60 of the column anchor 54 is arranged in one of the locking recesses 62 of the vertical column 56. This secures the vertical column 56 against removal from the column anchor 54. At the same time, the vertical columns 56 can be easily inserted into column anchors 54 of this design. This facilitates the construction of a building 34 with an exterior wall 36.

[0094] Fig. 11 shows the support structure of the building 34 with the vertical supports 56 as well as the roof support frames 58 arranged on the vertical supports 56 and the roof beams 52 arranged on the roof support frames 58.

[0095] Fig. 12 shows a cross-section through the building 34 in the area of ​​the building's exterior wall 36. It can be seen that the vertical support 56 is located inside a wall module 2. The beams of the roof truss frame 58 are arranged in the beam recess 30 of the wall modules 2. The connecting tongue and groove 28 of the floor slab edge insulation 46 is inserted into the connecting groove 32 on the underside 10 of the wall modules 2. This creates a continuous insulation layer on the building's exterior wall 36. As a result, the building 34 can be easily constructed in such a way that the building's exterior wall 36 has no or only minimal thermal bridges, and the building 34 can meet the high requirements for thermal insulation. Fig. 13 shows an arrangement of roof modules 50. These are shown again in Fig. 14. Fig. 14 shows a cross-section through the building 34 according to Fig. 4. The roof modules 50 each have a roof support recess 66 on one underside 64 of the roof module.The roof beams 52 are arranged in these roof beam recesses 66.

[0096] The cross-sectional view in Fig. 14 further shows that the roof modules 50 form connection areas 68. The roof modules 50 are connected to adjacent roof modules 50 or to the wall modules 2 of the building's exterior wall 36 via these connection areas 68. This provides a simple way to achieve continuous insulation. The connection areas 68 for connecting adjacent roof modules 50 are designed differently than the connection areas 68 for connecting roof modules 50 to wall modules 2.

[0097] In this embodiment, the roof modules 50 also consist entirely of insulating material and form an insulating layer. In this embodiment, the insulating layers consist of extruded polystyrene (XPS), polyurethane (PUR), or polyisocyanurate (PIR). Alternatively, another insulating material with a compressive strength of at least 100 kPa can be used. Using such insulating materials, roof modules 50 can be obtained that are lightweight and easy to process. In particular, the roof modules 50 can be easily produced with the required strength when using the aforementioned insulating materials. Figure 14 also shows the arrangement of door and window modules 40, 42 in the area of ​​a large, floor-to-ceiling window. Since the door and window modules 40, 42 also consist of insulating material, a window can be easily inserted into the opening defined by the door and window modules 40, 42.The window is automatically located within the insulation layer of building 34.

[0098] In this embodiment, the roof structure 48 of building 34 is designed to be self-supporting. No further vertical supports are required inside building 34. A flexible interior wall system can be used for partitioning the rooms inside building 34.

[0099] A flexible interior wall system according to the invention can comprise interior wall modules 70, as shown in Figures 15 and 16. The interior wall modules 70 shown in the exemplary embodiment are composed of three interior wall module elements 71. The interior wall module elements 71 are easily transportable and can be easily assembled to form interior wall modules 70. For assembly, the interior wall module elements 71 are provided with connection areas designed as tongue-and-groove joints. Interior wall modules 70 can also be obtained with more or fewer interior wall module elements 71. The interior wall modules 70 according to Figures 15 and 16 have rollers 72 on the underside and on the upper side of the interior wall module, by means of which the interior wall modules 70 can be easily moved inside the building 34. In the exemplary embodiment, the interior wall modules 70 are also provided with supply line recesses 24.On the upper surface of the inner wall modules, the inner wall modules 70 have fixing devices 74. Using the fixing devices 74, the inner wall modules can then be easily clamped between a floor of the building 34 and the roof structure 48 of the building 34 when they are moved into the correct position via the rollers 72.

[0100] The interior wall modules 70 can be easily arranged and positioned inside building 34. The placement of the interior wall modules 70 can be changed relatively easily at a later date, allowing building 34 to be adapted to changing usage requirements.
