Description

[0001] Building module and method for producing a building module

[0002] Technical area

[0003] The invention relates to a building module having at least one floor part, at least one ceiling part, and at least one reinforced concrete column, by means of which the ceiling part can be supported relative to the floor part, wherein the floor part and / or the ceiling part consists or consists at least partially of concrete. Furthermore, the invention relates to a method for producing a building module having at least one floor part, at least one ceiling part, and at least one reinforced concrete column, by means of which the ceiling part can be supported relative to the floor part, wherein the floor part and / or the ceiling part are made at least partially of concrete.

[0004] State of the art

[0005] A building module of the type mentioned above is known, for example, from DE 102020 002 272 A1. Compared to conventionally manufactured buildings, which require, for example, the construction of walls or the pouring of floors, walls, and / or ceilings at the respective construction site, a modular building formed from such building modules can be erected at the respective construction site with minimal manual and time expenditure by prefabricating the building modules, transporting them to the construction site, and connecting them together there.

[0006] Disclosure of the invention

[0007] An object of the invention is to provide a building module of the type mentioned at the outset, the use of which reduces the design freedom when designing a building formed therefrom.

[0008] This object is achieved by the independent patent claims. Advantageous embodiments are recited in the dependent patent claims, the following description, and the figures, whereby these embodiments, either individually or in combination with at least two of these embodiments, may represent an advantageous and / or further developing aspect of the invention. Advantageous embodiments of the building module may correspond to advantageous embodiments of the method, and vice versa, even if this is not explicitly referred to below.

[0009] A building module according to the invention has at least one floor part, at least one ceiling part and at least one reinforced concrete support, by means of which the ceiling part can be supported relative to the floor part, wherein the floor part and / or the ceiling part consist or consist at least partially of concrete, at least one connection receptacle is formed on the floor part and on the ceiling part, and the reinforced concrete support has a lower connection section which can be inserted into the connection receptacle on the floor part and an upper connection section which can be inserted into the connection receptacle on the ceiling part.

[0010] According to the invention, the reinforced concrete column is connected to both the floor section and the ceiling section via a type of plug-in connection, thereby creating a relatively large and robust connection area between the reinforced concrete column and the floor section or ceiling section. This allows transverse forces acting on the reinforced concrete column to be effectively transferred into the floor section without the need for additional measures, such as the additional attachment of bracing or the like, which would limit the design freedom in the configuration of a modular building, particularly in lateral wall areas between adjacent building modules. Instead, the building module according to the invention is reduced to a minimum of components, which also reduces the weight of the building module and reduces the assembly effort required to manufacture the building module.

[0011] The building module according to the invention can also have two or more, in particular four, reinforced concrete columns, via which the ceiling part can be supported against the floor part or connected to the floor part. For this purpose, four connection receptacles can be formed on the ceiling part and on the floor part. At least one connection receptacle can be designed as a through-opening or as a continuous opening over the height of the floor part or ceiling part. The geometry of a cross-sectional area of ​​a connection receptacle can, except for its overall dimensioning, essentially correspond to a cross-sectional area of ​​a connecting section of the reinforced concrete column that can be inserted therein. For example, these cross-sectional areas can be designed to be correspondingly polygonal.

[0012] The base part can be designed as a continuous base plate. The at least one connection receptacle of the base part can be arranged in an edge region of the base part.

[0013] The ceiling part can be designed as a continuous ceiling panel or in a frame-like configuration. The at least one connection receptacle of the ceiling part can be arranged in an edge region of the ceiling part.

[0014] The reinforced concrete column has steel reinforcement that is at least partially embedded in concrete. The reinforced concrete column can have a polygonal or circular cross-sectional area.

[0015] The building module according to the invention can be transported to the construction site of a modular building as a loose assembly or as a kit consisting of unconnected elements, comprising a floor section, a ceiling section, and one or more reinforced concrete columns, and assembled there to form the finished building module. Alternatively, the building module can be prefabricated in the factory as a fixed assembly consisting of a floor section, a ceiling section, and one or more reinforced concrete columns, by connecting the reinforced concrete column(s) to the floor section and ceiling section at the manufacturing site of the building module. The correspondingly prefabricated building module can then be transported to the construction site of the modular building. The finished building module can, for example, be cuboid-shaped.

[0016] The building module according to the invention serves to produce at least one room of a modular building, whereby the building should not be restricted to a specific building type. Such a modular building is also a subject of the present invention. The building module according to the invention can be designed to be stackable, so that two or more building modules can be stacked on top of one another to form multiple floors. The building modules according to the invention can also be arranged directly adjacent to one another to form a floor of a single- or multi-story modular building. A corresponding building thus represents a further aspect of the invention. At least one vibration-damping mat or layer made of an elastic material can be arranged between two building modules stacked on top of one another in order to achieve sound decoupling.

[0017] According to an advantageous embodiment, the upper connecting section is formed by an upper reinforcement section of a reinforcement of the reinforced concrete column and the lower connecting section is formed by a lower reinforcement section of the reinforcement of the reinforced concrete column, and at least one of the connecting sections, when inserted into the respective connection receptacle, is fixed in this connection receptacle by means of a grouting mortar. This forms a solid composite of the floor part, the ceiling part, and one or more reinforced concrete columns. For example, the grouting mortar can first be poured into the connection receptacle on the floor part, after which the lower connecting section of the reinforced concrete column can be inserted into this connection receptacle so that the grouting mortar penetrates the lower reinforcement section of the reinforced concrete column.Once the grout has hardened, the slab section can be placed onto the reinforced concrete column by placing the slab section's connection socket onto the upper connection section of the reinforced concrete column. The grout can then be poured from the top of the slab section into the connection socket on the slab section until the connection socket is completely filled with the grout. This grout can then harden.

[0018] In order to be able to lift the finished building module, an anchor, for example a nut, in particular a grouting nut, a hook, in particular a grouting hook, an anchor, in particular a grouting anchor, or the like, can be inserted into the connection receptacle on the ceiling part before this connection receptacle is filled with the grouting mortar. The grouting mortar can then be poured into the connection receptacle, whereby the anchor is partially cast into the grouting mortar. A lifting device, for example a crane, can be connected to the anchor after the grouting mortar has hardened in order to handle the building module. The anchor can also later be used as a support for a device of the modular building arranged above the building module, for example to support a roof element or the like.If such a building module is to be stackable, at least one device for at least partially receiving the anchoring and / or for mechanically connecting it to the anchoring can be formed on the underside of the floor part for each anchoring on the ceiling part.

[0019] According to a further advantageous embodiment, at least one steel profile and at least one steel bushing connected to the steel profile are embedded in the base part, wherein the steel bushing forms at least a section of one of the connection receptacles. The base part is mechanically reinforced by means of the steel profile. The steel profile can, for example, be arranged at the edge of the base part. The steel profile can, for example, have a T-shaped or I-shaped cross-sectional area or be designed, for example, as a rectangular tube, in particular a square tube, or a round tube. The steel bushing can, for example, have a polygonal, in particular rectangular or square, or round, in particular circular, cross-sectional area. A longitudinal center axis of the steel bushing is aligned perpendicular to a longitudinal center axis of the steel profile connected to it.The connection between the steel profile and the steel bushing allows the steel profile to absorb shear forces introduced into the steel bushing via the reinforced concrete column. The steel bushing can also be closed at one end, thus creating a cup-shaped structure. Two or more steel profiles and / or steel bushings can also be embedded in the base section.

[0020] According to a further advantageous embodiment, the steel profile and the steel bushing are embedded in the floor section in such a way that the floor section meets at least fire resistance class F90. The steel profile is thus enclosed by the concrete of the floor section in such a way that the floor section meets at least fire resistance class F90. The steel bushing is also preferably embedded in the concrete of the floor section in such a way that the floor section meets at least fire resistance class F90. This makes the building module particularly suitable for use in the construction of higher floors of a modular building. The fire resistance class F90 is taken from the German DIN standard DIN 4102-2 and corresponds to the fire resistance class R90 of the European standard DIN EN 13501-2.

[0021] According to a further advantageous embodiment, the floor section is rectangular, with a steel profile frame embedded in a peripheral edge section of the floor section. The frame comprises two parallel and longitudinally extending steel profiles, two parallel and transversely extending steel profiles, and four steel bushings. Each of the longitudinally extending steel profiles is connected to one of the transversely extending steel profiles via a steel bushing. This design of the floor section serves to create a cuboid-shaped building module. The steel profiles, together with the steel bushings arranged in the corner areas, form the rectangular steel profile frame. This gives the floor section optimal stability.

[0022] According to a further advantageous embodiment, the edge section of the floor part is partially formed from concrete. This provides the edge section, and thus the floor part as a whole, with the stability and robustness required for buildings. The edge section is preferably designed to completely enclose the steel profiles and / or the steel bushings of the steel profile frame. The edge section can be produced by pouring concrete, for example, fiber-reinforced concrete, into a mold, followed by curing the concrete. The edge section can be formed entirely from concrete except for the steel profile frame and any associated reinforcing elements or reinforcements.

[0023] According to a further advantageous embodiment, a central section of the floor part, which is enclosed by the edge section on the outside, is designed as a hollow floor, which has a wooden frame that lies on the inside around the edge section of the floor part, at least one upper wooden support layer that lies on the inside around the edge section of the floor part and is connected to an upper side of the wooden frame, and at least one lower wooden finishing layer that lies on the inside around the edge section of the floor part and is connected to an underside of the wooden frame. The presence of the hollow floor largely reduces sound propagation within the floor part, which makes a building formed by the building module quieter. The hollow floor can be essentially cuboid-shaped.At least one fastening element, for example a U-profile or the like, can be arranged on at least one steel profile of the steel profile frame, projecting inwards from the steel profile, to which the hollow floor can be fastened at the edge, for example by means of a screw connection or the like. The fastening element can be made of a metal or a metal alloy, for example steel. The wooden frame can have at least two wooden beams running parallel to one another, spaced apart from one another and longitudinally, and two wooden beams running parallel to one another, spaced apart from one another and transversely. The upper wooden load-bearing layer and / or the lower wooden finishing layer can be formed partially or completely from at least one particle board (OSB board). The upper wooden load-bearing layer and / or the lower wooden finishing layer can be screwed to the wooden frame.An insulating material, such as insulating wool, can be placed in a cavity between the upper wooden support layer and the lower wooden finishing layer. A metal sheet can be embedded in the insulating material, arranged parallel to the wooden support layer.

[0024] According to a further advantageous embodiment, the central section of the floor part has at least one gypsum fiberboard that extends circumferentially around the inside edge section of the floor part and is connected to an upper side of the upper wooden support layer, the upper side of which is arranged flush with an upper side of the edge section. The gypsum fiberboard can be glued to the upper side of the wooden support layer. The gypsum fiberboard enables automatic regulation of the humidity content of the room air in the finished building module.

[0025] According to a further advantageous embodiment, the floor section has a recess on its underside facing away from the ceiling section in a central section enclosed by the surrounding edge section. This results in material and weight savings. Furthermore, additional installation space is created in an area beneath the floor section, which can be used, if necessary, for installations of a further building module arranged below the building module. This further increases the design freedom when constructing a corresponding modular building.

[0026] According to a further advantageous embodiment, at least one reinforcement mat is embedded in the central section. This mechanically strengthens the central section of the base part.

[0027] According to a further advantageous embodiment, at least one reinforcing bar extending into the central section is fixed to at least one steel profile. This mechanically strengthens the transition edge region from the circumferential edge section of the floor part to the central section of the floor part. Preferably, several reinforcing bars are fixed to each steel profile. According to a further advantageous embodiment, the ceiling part is designed as a rectangular frame into which a steel profile frame is embedded. The frame has two parallel and longitudinally extending steel profiles, two parallel and transversely extending steel profiles, and four steel bushings, wherein each of the longitudinally extending steel profiles is connected to one of the transversely extending steel profiles via a respective steel bushing. This embodiment of the ceiling part serves to create a cuboid-shaped building module.The steel profiles, together with the steel bushings arranged in the corners, form the rectangular steel profile frame. This provides the ceiling section with optimal stability. Because the ceiling section is designed only as a frame, additional installation space is freed up in the area of ​​the ceiling section. This space can accommodate the installation of the building module, if required.

[0028] According to a further advantageous embodiment, the ceiling section is rectangular, with a steel profile frame embedded in a peripheral edge section of the ceiling section. The frame comprises two parallel and longitudinally extending steel profiles, two parallel and transversely extending steel profiles, and four steel bushings, with each of the longitudinally extending steel profiles being connected to one of the transversely extending steel profiles via a steel bushing. This design of the ceiling section serves to create a cuboid-shaped building module. The steel profiles, together with the steel bushings arranged in the corner areas, form the rectangular steel profile frame. This gives the ceiling section optimal stability properties.

[0029] According to a further advantageous embodiment, the edge section of the ceiling part is partially formed from concrete. This provides the edge section, and thus the ceiling part as a whole, with the stability and robustness required for a building. The edge section is preferably designed such that it completely encloses the steel profiles and / or the steel bushings of the steel profile frame. The edge section can be produced by pouring concrete, for example, fiber-reinforced concrete, into a mold, followed by curing of the concrete. The edge section can be formed entirely from concrete, except for the steel profile frame and any associated reinforcing elements or reinforcement elements.According to a further advantageous embodiment, a central section of the ceiling part, which is enclosed on the outside by the edge section of the ceiling part, is designed as a hollow ceiling, which has a wooden frame that adjoins the edge section of the ceiling part on the inside and at least one upper wooden finishing layer that adjoins the edge section of the ceiling part on the inside and is connected to an upper side of the wooden frame. The presence of the hollow ceiling largely reduces sound propagation within the ceiling part, which makes a building formed by the building module quieter. The hollow ceiling can be essentially cuboid-shaped.At least one fastening element, for example a U-profile or the like, can be arranged on at least one steel profile of the steel profile frame of the ceiling part, projecting inward from the steel profile, to which the hollow space ceiling can be fastened at the edges, for example by means of a screw connection or the like. The fastening element can be made of a metal or a metal alloy, for example steel. The wooden frame of the hollow space ceiling can have at least two wooden beams running parallel to one another, spaced apart from one another and longitudinally, and two wooden beams running parallel to one another, spaced apart from one another and transversely. The upper wooden finishing layer of the hollow space ceiling can be formed partially or completely from at least one particle board (OSB board). The upper wooden finishing layer of the hollow space ceiling can be screwed to the wooden frame of the hollow space ceiling.An insulating material, such as insulating wool, can be arranged in a cavity in the cavity ceiling which is enclosed on the outside by the wooden frame of the cavity ceiling.

[0030] According to a further advantageous embodiment, an upper side of the upper wooden finishing layer of the hollow space ceiling is arranged flush with an upper side of the edge section of the ceiling part, and / or an underside of the wooden frame of the hollow space ceiling is arranged flush with an underside of the edge section of the ceiling part. This flush design allows for ceiling parts with lower heights to be realized.

[0031] According to a further advantageous embodiment, the reinforced concrete column can be arranged in a corner area of ​​the floor section and the ceiling section. This embodiment is particularly suitable for a cuboid-shaped building module. According to a further advantageous embodiment, the connection receptacle and the connecting section each have a polygonal cross-sectional area. This allows torques acting on the reinforced concrete column or acting in the direction of the longitudinal center axis of the reinforced concrete column to be effectively transmitted to the floor section, making the building module even more robust.

[0032] According to a further advantageous embodiment, the reinforcement of the reinforced concrete column is thicker in a lower column section that can be connected to the floor section than in an upper column section that can be connected to the ceiling section. This takes into account the fact that greater mechanical loads typically occur in the lower column section than in the upper column section of the reinforced concrete column. For example, more longitudinally extending reinforcing bars can be arranged in the lower column section than in the upper column section.

[0033] According to a further advantageous embodiment, at least one connecting section is tapered. This creates a circumferential shoulder at the transition from this connecting section to the remaining reinforced concrete column, which can be supported on the upper side of the floor section facing the ceiling section or the underside of the floor section facing the ceiling section, further increasing the robustness of the building module.

[0034] According to a further advantageous embodiment, the floor section and / or the ceiling section are or are made at least partially of lightweight concrete. This further reduces the weight of the building module, which further simplifies its handling.

[0035] According to a further advantageous embodiment, at least one steel bushing is pot-shaped. The steel bushing is thus partially or completely closed at one end with respect to its longitudinal center axis, which gives the steel bushing greater stability and rigidity, resulting in structural advantages with respect to the steel profile frame and thus the entire building module.

[0036] According to a method according to the invention for producing a building module with at least one floor part, at least one ceiling part and at least one reinforced concrete column, by means of which the ceiling part can be supported relative to the floor part, the floor part and / or the ceiling part are produced at least partially from concrete, wherein at least one connection receptacle is formed on the floor part and on the ceiling part, a lower connection section of the reinforced concrete column is inserted into the connection receptacle on the floor part and an upper connection section of the reinforced concrete column is inserted into the connection receptacle on the ceiling part.

[0037] The method provides the advantages mentioned above with regard to the building module. In particular, the building module can be manufactured according to one of the above-mentioned embodiments or a combination of at least two of these embodiments using the method.

[0038] According to an advantageous embodiment, the reinforced concrete column is manufactured such that the upper connecting section is formed by an upper reinforcement section of a reinforcement of the reinforced concrete column, and the lower connecting section is formed by a lower reinforcement section of the reinforcement of the reinforced concrete column. At least one of the connecting sections, when inserted into the respective connection receptacle, is fixed in this connection receptacle by means of a grout. This embodiment provides the advantages mentioned above with reference to the corresponding design of the building module.

[0039] According to a further advantageous embodiment, production of the base part comprises:

[0040] Producing a steel profile frame comprising two mutually parallel and longitudinally extending steel profiles, two mutually parallel and transversely extending steel profiles and four steel bushings, by connecting each of the longitudinally extending steel profiles to one of the transversely extending steel profiles via a respective steel bushing;

[0041] Producing a hollow floor comprising a wooden frame, at least one upper wooden support layer connected to an upper side of the wooden frame, and at least one lower wooden finishing layer connected to an underside of the wooden frame;

[0042] Producing a floor assembly by attaching the hollow space floor to the steel profile frame so that the steel profile frame encloses the hollow space floor at a distance on the outside;

[0043] Placing the base assembly into a mold;

[0044] Pouring concrete into the mold so that the steel profile frame is embedded in the concrete; and

[0045] Hardening of the poured concrete in the mold.

[0046] During the production of the floor section, a surrounding edge of the hollow space floor is used as formwork for shaping the edge section of the floor section by pouring concrete, for example fiber-reinforced concrete, into the casting mold. This formwork simultaneously forms an essential component of the finished floor section. The casting mold is designed in such a way that the desired edge section of the floor section is created automatically or inevitably by pouring the concrete into the casting mold. The steel profile frame is embedded in the concrete without the steel bushings being filled with concrete. For this purpose, the floor assembly is first placed into the casting mold using a crane or similar, for example, inserted from above. The casting mold can be and remain open at the top.After the concrete has hardened, the floor section can be removed from the mold using a crane or similar device and used to manufacture the building module. To manufacture the floor assembly, the hollow space floor can be attached to the steel profile frame. For example, the steel profile frame has at least one inwardly projecting fastening element, for example a U-profile made of metal or a metal alloy, which can be welded to a steel profile of the steel profile frame and to which the hollow space floor can be attached using at least one fastening means, for example a screw connection. The fastening element can in particular be welded to a longitudinal steel profile (longitudinal profile) of the beam profile frame.To produce the hollow space floor, the rectangular wooden frame can first be made from longitudinal beams and cross beams, after which the at least one upper wooden load-bearing layer can be connected to the top of the wooden frame and the at least one lower wooden finishing layer can be connected to the underside of the wooden frame. Before the resulting cavity of the hollow space floor is closed with the upper wooden load-bearing layer or the lower wooden finishing layer, an insulating material, in particular thermal insulation material, can be introduced into the cavity. At least one sheet of metal can be introduced into the insulating material and arranged parallel to the upper wooden load-bearing layer or the lower wooden finishing layer. To produce the rectangular steel profile frame, the steel profiles can be welded to the steel bushings so that a longitudinal central axis of the respective steel bushing runs transversely to the plane of extension of the steel profile frame.

[0047] According to a further advantageous embodiment, production of the ceiling part comprises:

[0048] Producing a steel profile frame comprising two mutually parallel and longitudinally extending steel profiles, two mutually parallel and transversely extending steel profiles and four steel bushings, by connecting each of the longitudinally extending steel profiles to one of the transversely extending steel profiles via a respective steel bushing;

[0049] Producing a cavity ceiling comprising a wooden frame and at least one upper wooden finishing layer connected to an upper side of the wooden frame;

[0050] Producing a ceiling assembly by attaching the cavity ceiling to the steel profile frame so that the steel profile frame encloses the cavity ceiling at a distance on the outside;

[0051] Placing the ceiling assembly into a casting mold;

[0052] Pouring concrete into the mold so that the steel profile frame is embedded in the concrete; and

[0053] Hardening of the poured concrete in the mold.

[0054] During the production of the ceiling section, a surrounding edge of the hollow space ceiling is used as formwork for shaping the edge section of the ceiling section by pouring concrete, for example fiber-reinforced concrete, into the casting mold, whereby this formwork simultaneously forms an essential component of the finished ceiling section. The casting mold is designed in such a way that the desired edge section of the ceiling section is created automatically or inevitably by pouring the concrete into the casting mold, with the steel profile frame of the ceiling section being embedded in the concrete without the steel bushings of the steel profile frame of the ceiling section being filled with concrete. For this purpose, the ceiling assembly is first placed into the casting mold using a crane or the like, for example, inserted from above, whereby the casting mold can be and remain open at the top.After the concrete has hardened, the ceiling section can be removed from the casting mold using a crane or the like and used to manufacture the building module. To manufacture the ceiling assembly, the hollow space ceiling can be attached to the steel profile frame of the ceiling section. For example, the steel profile frame of the ceiling section has at least one inwardly projecting fastening element, for example a U-profile made of metal or a metal alloy, which can be welded to a steel profile of the steel profile frame of the ceiling section and to which the hollow space ceiling can be attached using at least one fastening means, for example a screw connection. The fastening element can in particular be welded to a longitudinal steel profile (longitudinal profile) of the beam profile frame of the ceiling section.To construct the hollow space ceiling, the rectangular wooden frame of the hollow space ceiling can first be constructed from longitudinal beams and cross beams, after which at least one upper wooden finishing layer of the hollow space ceiling can be connected to the upper side of the wooden frame. An insulating material, in particular thermal insulation material, can be introduced into the cavity of the hollow space ceiling, which is enclosed all the way around by the wooden frame of the hollow space ceiling. To construct the rectangular steel profile frame of the ceiling section, the steel profiles can be welded to the steel bushings so that a longitudinal center axis of the respective steel bushing runs transversely to the extension plane of the steel profile frame.

[0055] In the following, the invention is explained by way of example with reference to the attached figures using preferred embodiments, wherein the features explained below can represent an advantageous and / or further developing aspect of the invention both individually and in different combinations with one another.

The central section 33 or the hollow space ceiling has a rectangular wooden frame 34 that rests on the inside against the edge section 3 of the ceiling part 11. The wooden frame 34 has two longitudinal beams 35 running parallel to one another and longitudinally (of which only one longitudinal beam 35 is shown in Fig. 5), and two transverse beams running parallel to one another and transversely (of which one transverse beam is shown in Fig. 6). The longitudinal beams 35 and the transverse beams are formed from glued laminated timber with the layer structure shown. On the longitudinal beams 35, a separate step 47 is formed for each fastening element 28 or a step 47 which is continuous over the length of the longitudinal beam 35, with which the longitudinal beam 35 additionally rests on the fastening element 28 in order to support it on the floor side.

[0090] Furthermore, the central section 33 or the hollow space ceiling has at least one upper wooden finishing layer 37 that extends circumferentially around the inside of the edge section 3 of the ceiling part 11 and is connected to an upper side 36 of the wooden frame 34.
