[0043] Fig. 1a shows a schematic representation of an exemplary inner module of a residential building module with side walls at least partially composed of brick. An inner module is understood to be a module where several side walls (1008) and thus also their side wall elements (1014, 1016, 1018) are oriented towards further residential building modules. Inner modules are characterized by thinner side walls (1008) (for example, one or both long sides), whereas side walls (1020) that are intended to function as exterior walls (for example, one or both end walls) are thicker. Using side walls of different thicknesses allows, for example, different insulation measures and different structural requirements to be met, as well as weight and / or material savings.
[0044] Spaces (1028, 1030, 1032) (also called gaps) are shown between adjacent side wall elements (1014, 1016, 1018) of one or more side walls. Load-bearing elements (1022, 1024, 1026) (e.g., threaded rods) run vertically upwards from the base plate in these spaces, up to at least the height of the side wall.
[0045] Fig. 1b shows a schematic representation of an exemplary exterior module of a residential building module with side walls at least partially composed of brick. An exterior module is understood to be a module where several side walls (1006, 1008) and thus also their side wall elements (1014, 1016, 1018, 1020) are intended for use as exterior walls. Exterior walls are generally thicker than interior walls, for example for thermal insulation and / or structural reasons.
[0046] Distances (1028, 1030, 1032) are shown between adjacent side wall elements (1014, 1016, 1018, 1020), in which a load-bearing element (1022, 1024, 1026) (e.g. a threaded rod) extends vertically upwards from the base plate to at least the height of the side wall.
[0047] Fig. 2a shows a schematic representation of several interior modules placed directly next to each other. The side walls of the interior modules can be positioned essentially directly adjacent to one another; any gaps can be filled, for example, with insulation material and / or other materials. In the illustrated embodiment, the base plate (1002) comprises a cross-laminated timber panel. Furthermore, the side walls of the interior modules shown are thinner than those of a side wall intended for use as an exterior wall.
[0048] Fig. 2b shows a schematic representation of an inner module (left in Fig. 2b) and an outer module (right in Fig. 2b) placed directly next to each other. The adjacent side walls of the inner and outer modules can be positioned essentially directly against each other, as illustrated by the side walls shown on the left in Fig. 2b; any gaps can be filled with insulation material and / or other materials. In the present embodiment, the base plate (1002) comprises a cross-laminated timber panel. The outer module shown on the right in Fig. 2b has a thicker side wall on its right-hand side, which is intended for use as an outer wall.
[0049] Fig. 3 shows a schematic representation of an embodiment in which the base plates (1002) of the residential building modules are wood-based. The load-bearing elements (e.g., threaded rods) are connected to the base plate via steel angles with welded-on sleeves. The steel angles themselves are connected to the base plate via wood self-drilling screws (e.g., fully threaded screws, countersunk screws).
[0050] Figure 3 shows a spacer (e.g., a gap) and a side wall element located behind it. The load-bearing element extends vertically upwards from the base plate within this spacer. In another embodiment, the base plate (e.g., CLT panels) can contain sacrificial wood for electrical installations; for example, the base plate can also include sacrificial wood with milled recesses for electrical installations.
[0051] Fig. 4 shows a schematic representation of an embodiment in which the ceiling panels (1004) of the residential building modules are wood-based. As detailed in reference to Fig. 3, in a further embodiment the load-bearing element is attached to the ceiling panel by means of steel brackets and other components (dowels, fully threaded screws, countersunk screws). In another embodiment, the ceiling panel (e.g., a CLT ceiling panel) can contain sacrificial wood for electrical installations; for example, the ceiling panel can also include a sacrificial wood layer with milled recesses for the electrical installations.
[0052] Figures 5a and 5b show schematic representations of exemplary embodiments of a spacer for an inner module of Figure 1a and a spacer for an outer module of Figure 1b. As already explained above, inner and outer modules differ in the thickness of their walls. In the present illustration, two side wall elements of a side wall are shown, separated from each other by a spacer. A load-bearing element (e.g., a threaded rod) runs in the spacer between the two side wall elements. In one embodiment, the 7 L6454-027-WÖP00Pe The spacing is designed as a butt joint, whereby the butt joint can be mortared or fitted with a cover plate to enable, for example, a continuous, flat plastering.
[0053] Figures 5c and 5d show schematic representations of exemplary embodiments of a spacing of an inner module of Figure 1a and a spacing of an outer module of Figure 1b. In Figures 5c and 5d, the spacings for receiving the load-bearing element are formed between side wall elements of different side walls (1006, 1008), each forming a corner of an inner module or an outer module, respectively.
[0054] The advantages of positioning the load-bearing elements in gaps within the side walls of the residential modules, as shown in Figures 5a-5d, are described below in general terms for all embodiments. This allows the side wall elements to be prefabricated, enabling a modular construction of the residential module itself. Positioning the load-bearing elements within these gaps allows forces acting on the load-bearing elements (for example, when moving a residential module due to lifting forces acting on the load-bearing elements) to be transferred directly to the base plate without transferring forces to the side walls. Furthermore, positioning the load-bearing elements within these gaps allows prestressing forces to be exerted on the side walls or their side wall elements.This can be achieved, for example, by connecting a load-bearing element to the base slab and / or the ceiling slab in such a way that tensile forces are created between the base slab and the ceiling slab. Furthermore, it is possible for the load-bearing elements not to protrude from the base slab and / or the ceiling slab (i.e., not extend beyond the actual module). This allows residential modules to be easily "stacked." To move a residential module, the ends of the load-bearing elements that terminate in / at the ceiling slab are each fitted with a (removable) element, such as eyelets or hooks, to which a moving / transporting device (e.g., a crane or other transport equipment) can attach in order to move the residential module.Once the residential module has been positioned as desired, the element to which the moving transport device can attach can be removed and, for example, reattached for a later relocation of the residential module. Furthermore, the load-bearing elements improve the stability of a residential module, allowing for larger and / or more windows, doors, and / or clay / straw elements, or similar features.
[0055] In one embodiment, the ceiling panel can be a very thin layer of material (for example, sufficient to accommodate cables and conduits). In a particular embodiment, the ceiling panel (e.g., a CLT ceiling panel) has a thickness of at least 14 cm and thus acts as an additional stiffening element for the living space module (1000). In another particular embodiment, the ceiling panel (e.g., a CLT ceiling panel) has a thickness of at least 16 cm. In this case, the ceiling panel also includes sacrificial wood with milled recesses for necessary electrical conduits.
[0056] In one embodiment, the floor can be at least wood-based or made of wood; in another embodiment, the floor can be concrete-based or made of concrete.
[0057] Furthermore, the positioning of the load-bearing elements within the side walls of the residential building modules offers the advantage that the tensioning elements (i.e. load-bearing elements) do not run in the masonry, thus enabling simpler manufacturing.
[0058] Figure 6a shows a schematic representation of an exemplary residential module with at least a concrete-based floor slab for an interior module. Again, it is shown that the load-bearing elements (1022, 1024, 1026) run at several intervals between adjacent side wall elements of the side walls.
[0059] Figure 6b shows a schematic representation of a ceiling slab of an exemplary residential building module with a floor slab of an inner module that is at least concrete-based. The ends of the load-bearing elements (1022, 1024, 1026) are shown at the previously known positions. At the positions of the load-bearing elements, the residential building module (1000) can be connected to a moving device in order to be transported to different locations.
[0060] Figures 7a and 7b show schematic views of exemplary fastenings of the load-bearing elements (1022, 1024, 1026) in the concrete base slab. Figure 7a shows a section along a spacing between two adjacent side wall elements in a side wall of two adjoining interior modules. Figure 7b shows the spacing between two side wall elements of different side walls.9 L6454-027-WÖP00Pe
[0061] Fig. 8 shows a photographic view of a residential building module (1000) with a door (1036). Two side walls (1006, 1008) are shown, with side wall (1006) comprising a side wall element (1020). The side wall element (1020) includes a door and a brick wall. The other side wall (1008) comprises three side wall elements (1014, 1016, 1018), each of which includes a brick wall. The side wall element (1020) of side wall (1006) forms a gap (i.e., a space) (1028) together with the side wall element (1014) of the other side wall (1008). A load-bearing element, which is concealed by mortar in this illustration, runs within this space between adjacent side wall elements. The further distances (1030, 1032) are located between the adjacent side wall elements (1016, 1018) of the side wall (1008).The spacing (1034) is again present between the side wall element (1018) and a non-visible side wall element of the rear side wall.
[0062] Fig. 9 shows a different photographic view of the residential building module (1000) from Figure 8. In this illustration, the residential building module (1000) shows a side wall element with a large window opening. A ceiling panel is also shown, with the ends of the load-bearing elements provided with eyelets (1038) for transporting the residential building module (1000).
[0063] Fig. 10 shows another photographic view of the residential module (1000) from Figures 8 and 9, where it can be seen that the end walls of the residential module (1000) have a door and a large window opening.
[0064] Fig. 11 shows the implementation of a method for transporting a residential building module (1000). For this purpose, a moving device (1100), e.g., a stationary or mobile crane, is connected to the residential building module (1000) via the load-bearing elements. Subsequently, the residential building module (1000) can be moved by means of a moving device. In one embodiment, eyelets are screwed onto the load-bearing elements, so that the moving device (1100) can be connected to the residential building module (1000) via hooks.
