Description

[0001] The invention relates to a wall module, a wall system comprising several wall modules, and a method for constructing a building wall using several such wall modules.

[0002] Various methods for constructing load-bearing walls, non-load-bearing walls, partition walls and / or room dividers are known from the state of the art.

[0003] Due to increasing material requirements, stricter legal requirements regarding environmental compatibility, and a growing shortage of skilled workers, the construction industry faces the following challenges: 1. Construction has a significant ecological footprint: The construction sector accounts for 38% of global CO2 emissions. In Germany alone, 4.3 million tons of CO2 are released annually by the construction industry. 2. Demolition of buildings generates large quantities of materials that cannot be recycled, or only with considerable effort. These include soil, sand, natural stone, concrete fragments, ceramics, bricks, tiles, treated and untreated wood, metal parts, and asphalt. Electrical installation components, insulation materials, and pipes are also included. Even when building materials are recycled, they are largely of inferior quality and cannot be reused in the construction industry. 3. The demand for housing and infrastructure is increasing. Housing is a fundamental need. However, construction is becoming increasingly expensive, meaning that many people worldwide cannot afford safe and sustainable housing. 4.The production and transport of building materials is very energy-intensive. 5. The construction of buildings requires the employment of many skilled workers, who are increasingly in short supply.

[0004] Therefore, there is a need for sustainable building components that are cost-effective to manufacture, sustainable and easily recyclable in terms of the material used, and can be used without extensive specialist training under guidance with a high degree of self-help.

[0005] Wall element modules, for example made of wood, for the construction of walls are known from the prior art, e.g. from WO 2024 / 170494 A1. In this process, several identically designed wall element modules are stacked on top of each other to form a wall. The mechanical load transfer between the stacked wall elements is achieved primarily by means of joining elements provided in the area of ​​the end faces of the wall element modules.

[0006] For a precise and stable wall construction, the reciprocal arrangement of the joining elements and their dimensional accuracy are of some importance.

[0007] In contrast, the present invention is based on the objective of providing an improved wall module for the formation of a wall, which is particularly easy, precise and dimensionally accurate to manufacture and which, furthermore, also enables the construction of a wall in combination with similar wall modules, which involves low assembly or manufacturing tolerances, and which is also stable and easy to erect.

[0008] Furthermore, the wall module is intended to enable the construction of walls that, on the one hand, form a hollow and stable composite based on individual wall modules, and which, on the other hand, can be filled with filling and / or insulating material particularly easily.

[0009] These tasks are solved by the subject matter of the independent patent claims. Advantageous embodiments are each the subject matter of dependent patent claims.

[0010] In a first aspect, a wall module for constructing a building wall is provided. The wall module comprises a side wall structure that defines a cavity in one circumferential direction and has an upper lateral edge and an opposite lower lateral edge. The wall module further comprises a support structure structurally connected to the side wall structure, with at least one longitudinally extended support having a first longitudinal end and an opposite second longitudinal end. One of the first and second longitudinal ends of the support projects from the upper or lower lateral edge of the side wall structure, forming a projection. The other of the first and second longitudinal ends of the support is set back within the cavity by a predetermined offset from the other of the upper or lower lateral edge, forming a support receptacle.

[0011] The longitudinal extension of the projection is greater than the predetermined offset by a specified amount. In this way, a wall module can be brought into contact with an identical wall module along the longitudinal direction of at least one support, such that the projection of a support of, for example, a first wall module rests in the support recess of the adjacent second wall module. Because the projection is greater than the predetermined offset by a specified amount, and thus the depth of the support recess formed by the offset, the support of, for example, the first wall module rests against the support of the second wall module, and a load-bearing connection or support between the adjacent wall modules is thereby achieved exclusively or predominantly via the supports directly in contact.

[0012] The side wall structure can be located outside the load path between the support structures of adjacent wall modules, so that, in the case of wall modules arranged next to and / or above each other, no forces or no significant forces are transferred from a side wall structure of one wall module to the side wall structure of another adjacent wall module.

[0013] In this way, the side wall structure of the wall module can be designed to be comparatively delicate and thin-walled, since it does not perform, nor does it need to perform, any load-bearing function. Load transfer can be achieved solely and exclusively via the supporting structure and the mutual bracing of its beams through their alignment with the beams of the adjacent, typically stacked, wall modules.

[0014] The specified dimension by which the longitudinal extent of the extension is greater than the specified offset, and thus the specified penetration depth of the support, can be a few millimeters, approximately 1 mm to 5 mm, 1 mm to 3 mm, or 2 mm to 4 mm. In this way, for example, when stacking several wall modules on top of each other, the lower edge of a wall module positioned above it can be aligned with the adjacent upper edge of a wall module below it, maintaining a specified gap.

[0015] In this respect, a defined joint pattern can be generated between the superimposed side wall structures of superimposed wall modules, which can further contribute to a shapely and aesthetically pleasing appearance of the wall modules, or of the building wall formed by several wall modules.

[0016] Following further training, it is specifically stipulated that the side wall structure is designed to be closed in the circumferential direction and that an upper edge of the side wall structure forms a quasi-horizontal plane. Similarly, the lower edge of the side wall structure can form a horizontal plane or lie within a horizontal plane. The extension of at least one support of the support structure can project either upwards from the upper edge of the side wall structure or downwards from the lower edge of the side wall structure.

[0017] If the extension projects upwards from the upper edge of the side wall structure, the corresponding or complementary support receptacle is provided or formed on the underside, adjacent to the lower edge of the side wall structure. Conversely, the extension can also project downwards from the lower edge of the side wall structure. In this case, the corresponding or complementary support receptacle is located adjacent to the upper edge of the side wall structure.

[0018] In a further embodiment, it is specifically provided that the support structure comprises several individual supports spaced apart from one another in the circumferential direction of the side wall. The individual supports can be largely identical in design. For all or some of the supports, a projection can be provided from the underside, i.e., from the lower edge of the side wall structure. It is also conceivable that some or all of the projections protrude from the upper edge of the side wall structure. Correspondingly, complementary designs of the support mounts result, either adjacent to the lower edge or adjacent to the upper edge.

[0019] In some embodiments of the wall module, one or more supports may project from the upper side edge with their extension and project from the lower side edge of the side wall structure with one or more further supports. In such a configuration, the support structure is somewhat asymmetrical and necessitates the precise stacking of multiple wall modules with respect to a predetermined orientation and / or positioning relative to one another. For example, a wall module can only be placed on or engaged with a lower wall module in a single predetermined orientation relative to a lower wall module.

[0020] In a further embodiment, the side wall structure comprises several flat wall panels that adjoin each other, forming a circumferentially closed cavity and creating at least three side wall corners. These side wall corners can be configured to form any geometric shape within the side wall structure. Advantageously, a total of four side wall corners and four flat wall panels are provided, resulting in a cuboid shape for the wall module. However, triangular, square, pentagonal, or even hexagonal side wall structures are also conceivable.

[0021] In a further embodiment of the wall module, at least one longitudinally extended support abuts on its inner side a side wall corner formed by two adjacent flat wall panels. The wall panels that define or adjoin the side wall corner are connected to each other via the longitudinally extended support. In some embodiments, the support can have a longitudinally extended beam or a longitudinally extended support profile, for example in the form of a square profile.

[0022] In the case of a square profile with a rectangular or square cross-sectional geometry, the outer sides of the profile are arranged at right angles to each other. Therefore, the edge sections of adjacent wall panels can abut different adjacent profile sides of such a square profile in the area of ​​the side wall corners and be structurally connected to it.

[0023] By means of the longitudinally extended support, for example in the form of a longitudinally extended square support profile, mutual fastening and fixing of wall panels can be achieved, where they adjoin each other at a joint and simultaneously form a side wall corner. The support, i.e., the support profile or the beam formed by the support, is typically located within the cavity formed by the side wall structure. It is always located in or at an inside corner of the side wall, so that the outside of the side wall structure is free of support and the support is virtually concealed by the adjoining arrangement of at least two wall panels in the area of ​​the side wall corner and is not visible from the outside in the final installed position.

[0024] In a further refinement of the wall module, the flat wall panels forming a side wall corner are spaced apart from each other in the area of ​​the respective side wall corner, forming a joint that extends through the side wall structure. The wall panels forming or contributing to a side wall corner and adjacent to each other approximately circumferentially do not abut each other directly. They can be aligned or arranged butt-jointed. However, a predetermined gap is maintained, for example, to acoustically and / or mechanically decouple the wall panels from one another.

[0025] The wall panels adjacent to the side wall corner can be arranged and fastened against each other via the support beam on the inside, creating a joint at the outer corner of the side wall that extends along the beam or parallel to its longitudinal direction. This joint can have a predetermined dimension or gap, dimensioned to allow, for example, the insertion of a profile element, such as a tongue-and-groove profile, to cover the joint between adjoining side wall structures of different and adjacent wall modules.

[0026] In a further embodiment, the side wall structure features a longitudinally extending groove with a predetermined groove depth, at least in sections, along at least one of the upper and lower side edges. In this way, a tongue profile can be inserted at the upper side edge and / or at or along the lower side edge, by means of which an airtight or windproof arrangement of stacked wall modules can be achieved.

[0027] Because the extension of the support is larger by a predetermined amount than the predetermined offset of the complementary support receptacle, a predetermined gap or a predetermined gap dimension can be achieved between the upper side edge of a lower wall module and the lower side edge of an upper wall module when several wall modules are stacked on top of each other.

[0028] By forming a longitudinal groove along the upper or lower edge of the wall panel, approximately over its entire length, a tongue profile can be inserted into that groove to bridge the gap.

[0029] In a further embodiment, the wall module is designed with a spring profile. The spring profile can be provided as a separate component for the wall module. The spring profile can be inserted into the longitudinal groove and, in the insertion direction into the longitudinal groove and perpendicular to the profile direction, has an insertion profile extent that is less than twice the groove depth. In this way, it can be ensured that no or negligible forces are transmitted between the adjacent side wall structures of a first and a second wall module, which are arranged one above the other, via the side wall structures that abut each other at their lower and upper edges.

[0030] By ensuring a sufficiently large groove depth, the spring profile can never reach the bottom of the groove. This effectively prevents the spring profile from engaging with the longitudinal groove and transmitting force.

[0031] According to a further embodiment, it can also be provided that a longitudinally extending groove runs along the lower side edge and a longitudinally extending groove runs along the upper side edge, each with a predetermined groove depth. The sum of the groove depths is greater than the corresponding extent of the spring profile provided for this purpose, which has an insertion profile extent in both directions, in the insertion direction and perpendicular to the profile direction, that is smaller than the sum of the two groove depths.

[0032] In this way, mechanical support of the overlapping side wall structure, for example via the groove and its engagement with a longitudinally extended spring profile at the upper and lower side edges, can be effectively prevented.

[0033] The longitudinally extended spring profile 48 in Fig. 10 When multiple wall modules are arranged to construct a building wall, the tongue profile performs various functions. Besides ensuring the flatness of the stacked wall modules, it acts as a vapor barrier on the inside of the wall module and as an airtight seal on the outside.

[0034] After further development of the wall module, the side wall structure has an outer side wall section and an opposite inner side wall section in relation to the building wall to be erected later, as well as an end wall section at the longitudinal ends of the outer side wall section and the inner side wall section, each defining the cavity.

[0035] In this configuration of the wall module, the module is typically cuboid in shape. However, it is designed without a base or a top. Therefore, the wall module can consist solely of a support structure comprising several beams and a side wall structure. The side wall structure comprises a total of four wall panels, which adjoin each other at the four corners of the side wall, forming a circumferentially closed cavity. At each boundary or joint area of ​​the wall panels, a longitudinally extending beam of the support structure, extending approximately vertically, is provided or implemented.

[0036] In a further modification of the wall module, the outer side wall section is made of a vapor-permeable material. Specifically, the corresponding wall panel can be made of a vapor-permeable material, particularly one that is vapor-permeable to water vapor. The wall panel can, for example, be made of wood fiberboard, such as a so-called DWD panel. In this way, any moisture penetrating the cavity can escape from the cavity of the wall module through the outer side wall section.

[0037] In a further refinement of the wall module, it is also provided that the inner side wall section and / or the end wall sections are designed to be watertight and / or impermeable to water vapor. For this purpose, suitable panel or panel materials acting as a water vapor retarder or vapor barrier are provided, such as oriented strand board (OSB3) or plywood (FU) panels.

[0038] In this way, it can be prevented that moisture from the inside, i.e. from the interior of a building, penetrates into the interior of the wall module, i.e. into the cavity of the wall module.

[0039] According to a further embodiment, at least one handle hole is formed in the side wall structure, extending through the side wall structure. It can, for example, be located in an end wall section of the side wall structure, which, in the case of an arrangement of several wall modules side by side, will be adjacent to a neighboring end wall section of a neighboring wall module, so that when the building wall is erected, the side wall sections running between the end wall sections do not have such a handle hole, but are designed without one.

[0040] The inner or outer wall of the erected building wall, formed by the corresponding side wall sections of several wall modules arranged next to and above each other, can therefore be free of handle holes.

[0041] The arrangement or design of the handle hole penetrating the side wall structure in an end wall side of the side wall structure is no longer visible when several wall modules are arranged next to and / or on top of each other in the corresponding final assembly configuration.

[0042] The handle hole is typically sized so that an end user or installer can, for example, reach through or into the hole with a finger, such as an index or middle finger, making the wall module particularly easy to handle.

[0043] The handle hole is typically located or formed near the upper edge of the side wall structure. It can be positioned closer to the upper edge than to the lower edge. Therefore, the handle hole penetrating the side wall structure can be located above the geometric center of gravity of the wall module, so that when the wall module is handled using the handle hole, it exhibits no or only minimal gravity-induced wobbling or pivoting movements when lifted or handled, for example, when grasped and lifted by the handle hole.

[0044] According to a further aspect, the present invention also relates to a wall system for erecting a building wall. The wall system comprises several wall modules as described above, wherein a second wall module can be stacked on a first wall module in such a way that the extension of the support structure of one of the first or second wall modules comes to rest in a support receptacle of the other of the first or second wall module.

[0045] In the support recess, which is limited in the vertical direction, i.e. along a vertically oriented joining direction of the first and second wall modules, by a longitudinal end of the support, the extension of the support of the respective other wall module can come into contact with it in a supporting manner, so that vertically acting forces, in particular the gravity of the second wall module which loads on the first wall module, can be carried out exclusively or predominantly via the mutual contact of supports of the second and first wall modules.

[0046] Since the wall system has several wall modules described above, all properties, advantages and effects described with regard to the wall modules also apply equally to the wall system; and vice versa.

[0047] The first and second wall modules of a wall system are essentially identical in construction. The extension of a support, which protrudes either from the lower or upper edge of the side wall structure, corresponds to a complementary support receptacle of the other wall module, formed on opposite edges, i.e., at the upper or lower edge.

[0048] If, for example, the wall module has a support beam in a side wall corner that projects from the lower edge of the side wall structure, then the same wall module will also have an identically designed second wall module opposite it, i.e., at the upper edge in the same side wall corner, with a support beam receptacle designed complementarily to the projection. A complementary support beam receptacle means that the offset of a longitudinal end of a beam defining the support beam receptacle is less than the extent of the projection that projects from an upper or lower edge of the side wall structure.

[0049] This allows multiple wall modules to be stacked on top of each other. In particular, the wall modules are intended to be stacked without offset, i.e., aligned without any offset with respect to a horizontal direction, so that the side wall structure of a first wall module is virtually flush with the side wall structure of the second wall module, which is positioned or stacked above or on top of the first wall module.

[0050] In a further embodiment of the wall system, in a stacked configuration where the second wall module is arranged or stacked on top of the first wall module, the lower edge of the side wall structure of the second wall module is spaced from the upper edge of the side wall structure of the first wall module by maintaining a gap. This gap distance or dimension results from the fact that the longitudinal extent of the extension, i.e., the portion of the extension projecting from the upper or lower edge, is greater by a predetermined amount than the predetermined offset by which the support receptacle is offset along the vertical joining direction from the opposite edge of the side wall structure.

[0051] The specified dimension by which the longitudinal extension of the extension is greater than the specified offset of the support defines the gap distance formed between the upper side edge of the side wall structure of the lower, i.e., the first wall module and the lower side edge of the side wall structure of the upper, i.e., the second wall module.

[0052] In a further embodiment of the wall system, the extension of a support structure of the first or second wall module is attached and / or fixed in the area of ​​the support receptacle of the other wall module by means of a separate fastening element. In this way, the interlocking configuration of extension and receptacle can be fixed in a final assembly position in which a second wall module is arranged or stacked on top of the first wall module. The fastening element can be designed, for example, as a screw, a rivet, or a similar joining element. It can, for example, be passed horizontally or obliquely through the overlapping arrangement of the side wall or side wall structure of the first or second wall module and through a corresponding extension of the other, i.e., the second or the first, wall module.

[0053] In a further embodiment of the wall system, horizontally adjacent side wall structures of adjacent wall modules can be structurally connected in the area of ​​directly adjoining end wall sections by means of a fastening element that at least partially penetrates the adjacent end wall sections. Since the individual wall modules each form a cavity, they can be fixed to each other or to each other after assembly, in which the support of one wall module rests in corresponding support receptacles of the other wall module, using separate fastening elements. The fastening elements penetrating the end wall sections of the side wall structure can, for example, be implemented as screws or bolts.

[0054] The wall system and individual wall modules can be made of wood or engineered wood products. Engineered wood products include, in particular, solid wood products, veneer products, particleboard, wood fiber products, and composite materials, such as wood-plastic composites. Both the side wall structure and the supporting structure can be made of engineered wood products.

[0055] The corresponding fastening elements can then be designed, for example, as wood screws, perhaps made of metal, and can be inserted or anchored or screwed into the adjacent end wall sections in a particularly simple manner, namely by screwing them into or through them.

[0056] In further embodiments, the wall module or wall system can also be made of a plastic or a plastic composite material. The support structure and / or the side wall structure can be made entirely or partially of a plastic or plastic composite material. Furthermore, it is conceivable that only individual wall panels of the side wall structure, such as individual side wall sections and / or end wall sections, are made of a plastic or a plastic composite material.

[0057] The cavity of the wall modules, or a column of wall modules within a wall system, serves primarily to accommodate one or more filling materials. Depending on the requirements, the cavity can be filled with a wide variety of materials. For use as an exterior wall, the filling material can have particularly good thermal insulation properties. The insulation and / or filling material can consist of various sustainable materials, such as straw, clay, wood or cellulose fibers (installed as a pre-assembled element or blown in at a later stage), or any other material with thermal insulation properties.

[0058] Plastics, such as recycled plastics like shredded polyethylene (PET) from recycled material (e.g., used PET bottles), other types of plastic, and even used clothing, can also be used as filling and / or insulation materials. Some regions of the world are struggling with large quantities of plastic waste that massively pollutes not only the oceans but also rivers. By using recycled plastic waste or used clothing as filling material, these materials can be given a useful purpose and essentially upcycled.

[0059] If requirements regarding sound insulation or thermal storage capacity are placed on the wall, as is usually the case with load-bearing and non-load-bearing interior walls, the filling can also be done with "heavy" material such as clay, bulk material or construction debris.

[0060] The wall system allows for the construction of a wide variety of wall types. To meet diverse requirements, the dimensions of the wall modules, side wall sections, and end wall sections can vary considerably. The thickness of the wall module sections can be adjusted according to structural and building physics requirements.

[0061] With appropriate design of the wall module dimensions and thickness of the materials or panels used, load-bearing walls, non-load-bearing walls, partition walls, temporary partition walls, exterior walls, load-bearing interior walls and non-load-bearing interior walls can be erected with the wall modules.

[0062] The cuboid side wall structure can preferably have the following dimensions: a longitudinal extension in the longitudinal direction from a first end wall section to the opposite second end wall section of 400 mm to 1200 mm and / or a transverse extension in the transverse direction from a first side wall section to an opposite second side wall section of 80 mm to 500 mm and / or a vertical extension in the vertical direction from a lower side edge to an opposite upper side edge of 250 mm to 600 mm, preferably 400 mm to 600 mm.

[0063] The wall sections of the side wall structure of the wall module are preferably made of sheet material. The wall panels of the side wall structure preferably have a thickness of 8 mm to 20 mm, in particular a thickness between 10 mm and 18 mm, and more preferably a thickness between 12 mm and 16 mm.

[0064] For the construction of an exterior wall, the wall panels preferably have the following dimensions: Dimensions of side wall section: 800mm (width) x 500mm (height) x 16mm (thickness), Dimensions of front wall section: 400mm (width) x 500mm (height) x 16mm (thickness).

[0065] For the construction of a load-bearing interior wall, the wall panels preferably have the following dimensions: Dimensions of side wall section: 800mm (width) x 500mm (height) x 16mm (thickness), Dimensions of front wall section: 240mm (width) x 500mm (height) x 16mm (thickness).

[0066] For the construction of a non-load-bearing interior wall, the wall panels preferably have the following dimensions: Dimensions of longitudinal wall: 800mm (width) x 500mm (height) x 16mm (thickness), Front wall dimensions: 100mm (width) x 500mm (height) x 16mm (thickness).

[0067] In a further aspect, the present invention relates to a method for erecting a building wall, such as an interior or exterior wall. The method comprises the steps of providing several of the previously described wall modules and stacking at least one second wall module on top of a first wall module. Typically, the method includes stacking further wall modules on top of the second wall module, for example, stacking a third wall module on top of the second wall module, and stacking or arranging a fourth wall module on top of the third wall module.

[0068] Furthermore, additional modules can be stacked on top of each other and arranged next to the already stacked wall modules. It is also conceivable to initially arrange several wall modules side by side with their end faces adjacent, so that their side wall sections are aligned. The adjacent end wall sections of neighboring modules can then be fixed or connected to each other, resulting in an elongated, layered structure of the building wall.

[0069] Following this, several layers of additional wall modules can be arranged on top of the already positioned or aligned lower wall modules until a building wall of the required height and width is erected.

[0070] Since the process is based on the provision and intended use of the wall modules described above, all characteristics, advantages, applications and effects described with regard to the wall modules and the wall system also apply equally to the process; and vice versa. Brief description of the characters

[0071] Further objectives, features, and advantageous applications of the wall module, the wall system, and the method for constructing a building wall are explained in the following description of an exemplary embodiment with reference to the figures. These figures show: Fig. 1 a perspective view of an example of a wall module, Fig. 2 a base profile for a wall system, Fig. 3 an end piece for the wall system, Fig. 4 an arrangement of several wall modules for the construction of a building wall, Fig. 5 a representation according to Fig. 4however, with a floor profile, Fig. 6 a side view of the wall module, Fig. 7 a side view of the wall module rotated by 90°, Fig. 8 a top view of the wall module from above, Fig. 9 a schematic representation of the arrangement of several wall modules, or a wall system, in relation to a floor or story structure, and Fig. 10 an enlarged section of a part of the wall according to Fig. 9 . Detailed description

[0072] The in the Figures 1 to 10The wall module 10 shown has a side wall structure 11 with several flat side wall sections 14, 18 and intervening end wall sections 12, 16. The side wall structure 11 is cubic in shape. The individual wall sections are each formed by a wall panel. Thus, the end wall section 12 is formed by a wall panel 32. The side wall section 14 is formed by a wall panel 34. The end wall section 16 is formed by a wall panel 36, and the side wall section 18 is formed by another wall panel 38.

[0073] In the embodiment shown here, the side wall structure 11 comprises a total of four side wall corners 31, which are formed by butting together the respective facing ends of the individual wall panels 32, 34, 36, 38. The vertical extent of the individual side wall sections 14, 18 and end wall sections 16, 18 is essentially identical, so that the side wall structure 11 formed by the individual wall sections has an upper side edge 13 lying essentially in one plane and an opposing lower side edge 17.

[0074] The individual wall panels 32, 34, 36, 38 are designed as closed wall panels. The wall module 10 is designed without a base or top. That is, it is open in the vertical direction and only has the side wall structure 11 and a support structure 20 that mechanically stabilizes the side wall structure 11. The support structure 20, which is structurally connected or coupled to the side wall structure 11, comprises individual beams 21, 22, 23, 24. The individual beams 21, 22, 23, 24 can each be designed as a beam 25 with an upper longitudinal end 26 and an opposite longitudinal end 27.

[0075] The longitudinal ends 26, 27 are characterized by planar surfaces, for example, planar end faces 28, 29, whereby the orientation of the end faces 28, 29 need not necessarily be planar or parallel to the plane of the upper side edge 13 or the lower side edge 17. Thus, and in the illustrated embodiment, the upper longitudinal end 26 has a planar or flat end face 28. The lower longitudinal end 27 has a complementary, also planar, lower end face 29.

[0076] The individual beams 21, 22, 23, 24 can be unconnected to one another. That is, the individual beams 21, 22, 23, 24 do not have to be directly connected or mechanically coupled to one another. Therefore, it is provided that the individual beams 21, 22, 23, 24 are each designed as a square profile 30, for example, as square timber. They can have the same lengths and can, in particular, be arranged on the inside in the respective side wall corners 31. The individual beams 21, 22, 23, 24 can, as shown in particular in Fig. 8 As shown, for example, a first profile side 42 abuts an inner side 40 of a second wall section 14. Another profile side 44 of the support 23 can, for example, be arranged against an inner side 41 of an end wall section 16.

[0077] By arranging the individual supports 21, 22, 23, 24 in or on the inner sides of the side wall corners 31, the areas of the side wall structure 11 adjacent to the side wall corners 31, and thus the respective wall panels 32, 34, 36, 38, can be structurally connected to one another. For example, the end wall section 16 can be connected to the side wall section 14 via the support 23. The opposite end of the side wall section 14 can be connected to the further end wall section 12 by means of or via the support 22.

[0078] An opposite end of the end wall section 12 can be connected to the side wall section 18 via the support 21, and that side wall section 18 can, in turn, be connected to the end wall section 16 via another support 24 at its opposite outer edge. In the side wall corners 31, the individual wall panels 32, 34, 36, 38 can be arranged relative to each other, maintaining a joint 33, 35, 37, 39. In this way, for example, acoustic decoupling of the end wall panels 32, 36 from the longitudinal wall panels 34, 38 can be achieved.

[0079] Furthermore, the joints 33, 35, 37, 39 allow for the arrangement and insertion of appropriately designed spring profiles (not shown), which, when at least two wall modules are arranged end-to-end, bridge the gap between the wall modules and thus enable an airtight and flow-tight connection between the otherwise butt-jointed end wall faces 12, 16 of adjacent wall modules 10, 10'. In addition, when several wall modules are arranged to construct a building wall, the inserted spring profiles also ensure that the wall modules are flat.

[0080] The side wall section 14 can be designed as an external side wall section. In particular, it can be designed to be water vapor permeable or diffusion-open.

[0081] The opposite side wall section 18 and / or the end wall sections 12, 16, however, may have a water vapor barrier.

[0082] As can be seen particularly from a synthesis of the Figure 1 and 6 As can be seen, one of the first longitudinal end 26 and second longitudinal end 27 of each support 21, 22, 23, 24 protrudes from a lower lateral edge 17 of the side wall structure 11, forming a process 55. The opposite longitudinal end, in this case the upper longitudinal end 26, is furthermore arranged in a support receptacle 50, offset from the other, i.e., from the upper lateral edge 13, by a predetermined distance within the cavity 15 bounded by the side wall structure 11.

[0083] The longitudinal extent L of the extension 55 is greater by a predetermined amount than the offset V. In this way, when stacking several wall modules 10, 10', 10" on top of each other, it can be achieved, for example, that the extensions 55 of the beams 21, 22, 23, 24 projecting from the lower side edge 17 are inserted complementarily into correspondingly designed beam receptacles 50 in the wall module 10 below.

[0084] Because the longitudinal extent L of the extensions 55 is greater by a predetermined amount, namely by a gap dimension, than the predetermined offset V, a defined gap 68 can be formed between the side wall structures 11 of superimposed wall modules 10, 10' between the upper side edge 13 of the lower wall module 10 and the lower side edge 17 of the upper wall module 10'.

[0085] In a stacked configuration, where a second wall module 10' is arranged on top of the first wall module 10, the side wall structures 11 do not come into contact with each other, or rather, they are not coupled to each other in a load-transferring manner. The mechanical load transfer and the mechanical stress, for example, to support the self-weight of the wall modules above, is carried out exclusively or predominantly via the stacked beams 21, 22, 23, 24, which are supported on each other by their respective end faces 28, 29.

[0086] As especially in Fig. 10The individual wall panels 34, 38, as well as wall panels 32, 36, can be connected to the internal supports 21, 22, 23, 24 at designated fastening points 52, 53. For example, they can be screwed to the internal supports 21, 22, 23, 24 at fastening point 53. Wall panels 34, 38 can be connected to the adjacent supports, such as support 22, at fastening point 53. The end wall panels 32, 36, in this case wall panel 32, can be structurally connected to the same support 22 at another fastening point 52.

[0087] The fixing points 52, 53 can be screw holes or define fixing points suitable for a screw connection with the respective adjacent wall plate 32, 34, 36, 38. As particularly in Fig. 10As shown, the fastening points 52, 53 are arranged at a predetermined angle to each other. They can, in particular, be oriented perpendicular to each other. For improved hold and fixation, as well as for reduced mechanical stress on the supports 21, 22, 23, 24, the fastening points 52, 53 can be offset from each other longitudinally along the supports 21, 22, 23, 24.

[0088] The further and in Fig. 10 The depicted fastening point 51 serves to connect or fix stacked wall modules 10, 10', 10" to one another. For example, a screw opening or through-hole can be provided in the wall panel 12 as a fastening point 51, which ends on the inside of the side wall structure 11 in the area of ​​the support receptacle 50. In the Fig. 10In the assembly configuration shown, a lower longitudinal end 27 of a support of a further wall module 10" comes to rest in the upper support receptacle 50 of a lower wall module 10' arranged below. The fastening point 51 can be used in particular for a separate and in Fig. 8 The indicated fastening element 78 is designed or provided, which is designed, for example, as a screw and can be engaged or screwed into the end wall section 12 of the first module 10 and into a projection 55 of the second module 10' which lies in its support receptacle 50.

[0089] By screwing a screw or similar fastening element in the area of ​​the fastening point 51 and approximately along the surface normal through the end wall section 12 or through the wall plate 32, a direct reciprocal connection can be formed between the lower wall module 10 and the upper wall module 10'.

[0090] The end walls 12, 16 of the e.g. in the Figures 4 and 5 Modules 10 10" arranged side by side and at the same height can also be fixed and fastened to each other or to each other with separate fastening elements 79, which at least partially penetrate the adjacent end wall sections 12, 16.

[0091] As particularly in the representations according to the Figure 1 and 6 As shown in Figure 10, the wall panels 34, 38 of the side wall sections 14, 18 each have a longitudinally extending groove 43 at the upper side edge 13 and, opposite this, another groove 47 at the lower side edge 17, each extending over the entire longitudinal extent of the upper and lower side edges 13, 17. These grooves 43, 47 are designed and configured to receive a tongue profile 48.

[0092] The spring profile 48, in the insertion direction into the groove 43, 47 and perpendicular to the longitudinal extent of the respective grooves 43, 47, has a profile extent that is less than half the respective groove depth. In other words, and if the grooves 43, 47 have different groove depths, the profile extent of the spring profile 48 is smaller or shorter than the sum of the groove depths of the two grooves 43, 47, which are to be aligned one above the other in the final assembly configuration shown. In this way, the gap 68 formed between the overlapping side wall sections 11 can be effectively closed by means of the spring profile 48 without, however, forming a mechanically load-bearing connection between the aligned side wall sections 11 of the first and second wall modules 10, 10' arranged one above the other.

[0093] To form a building wall 5, several of the wall modules 10, 10', 10" shown here are to be stacked on top of each other, as for example in Fig. 9 shown. Furthermore, several such wall systems 1 made of wall modules 10, 10', 10" are to be placed next to each other. Because the individual modules 10, 10', 10" are designed without a bottom, column-like hollow bodies are formed which can be filled from above with a filler material, such as insulation material.

[0094] The building wall 5 can, if necessary, also be made up of several individual modules 10', 10", 10' as in the Figures 4 or 5 shown, formed, or essentially consisting of this. The number of stacked wall modules (10, 10', 10") can be varied according to the desired wall height.

[0095] The building wall 5 can be provided with a base profile 60 at its bottom, which is designed to complement the geometric shape of the lower side edge 17 of the wall module 10. In the present embodiment, and if, for example, the wall modules 10, 10', 10" have downwardly projecting extensions 55 from the lower side edge 17, the base profile 60 can have a support bearing 61 and a plinth section 62 raised from the support bearing, such that the plinth section 62, viewed transversely to the longitudinal direction of the base profile 60, lies between the downwardly projecting extensions 55 of the supports 21, 22, or 23, 24, which are spaced apart from each other at the end wall sections 12, 16. In this way, the end face of the building wall 5 or wall system 1 thus formed can be closed in the longitudinal direction.

[0096] As further in Fig. 9As shown, the floor profile 60 can be arranged on a base section 66 of a floor or story structure 64 of a building and provide a defined interface for the arrangement and fastening of a wall system 1, or a building wall 5 formed therefrom, on or to the floor or story structure 64.

[0097] The upper wall module 10' of a wall system 1 or a building wall 5 can further be fitted with an end piece 70 according to Fig. 3 The end piece 70 may have a cover section 71, which has a geometry or surface that essentially corresponds to the cross-sectional geometry of the side wall structure 11. On its inner side, the cover section 71, which may, for example, be designed as a flat plate, may have downwardly projecting extensions 75 at its edges, which can be inserted into the correspondingly designed support receptacles 50 of the uppermost or uppermost wall module 10".

[0098] Furthermore, a downwardly projecting groove 74 can be provided on or along the outer edge, i.e. on the opposite cover edges 72, 73, which is designed to be complementary to the groove 43 of the uppermost wall module 10" and is designed to accommodate a further spring profile 48, which is not explicitly shown here.

[0099] In this way, the building wall 5 can be sealed airtight. The individual wall modules 10, 10', 10" can, for example, each have a handle hole 45 located above the geometric center of gravity of the respective wall module 10 in sections 12, 16, which simplifies the handling of the individual wall modules 10 for the construction of the building wall 5.
