Description

Construction board for building installation and its production

[0001] The present disclosure relates to a method for producing a building panel with an embedded functional element for building installations. The present disclosure further relates to a building panel with an embedded functional element for building installations, which can be produced in particular using the method according to the disclosure.

[0002] From DE 19962 501 A1 a wall or ceiling cladding made of separate plate-shaped elements is known, which have a cladding panel, in particular a plasterboard or gypsum fiberboard, on the visible side.

[0003] From DE 202010 004 015 U1 a closable inspection opening for drywall construction is known, comprising a perforated plate with an opening and a perforated cover for covering the opening, wherein the plate has an opening edge delimiting the opening and the cover has a cover edge.

[0004] EP 0 891 858 A2 discloses a sandwich panel with an integrated profile for fastening purposes, which is particularly suitable for use in vehicle construction. The profile is inserted into the sandwich panel from a front side, so that, on the one hand, a large-area covering is required and, on the other hand, any tensile loads are only inadequately absorbed by the sandwich panel.

[0005] A wide variety of buildings feature wall and ceiling cladding, which is typically made of plasterboard or similar materials. In commercial buildings (including offices, retail spaces, and the like), as well as in residential buildings, suspended ceilings, partition walls, and the like can be created using drywall construction.

[0006] Wall and ceiling paneling often also serve to cover and / or accommodate equipment for building installations. This includes, for example, air conditioning, cooling, and / or heating. This also applies to supply lines (power supply, water supply, heating circuits, cooling circuits, and the like), data lines (network lines, telecommunications cables, TV cables, and the like), other building services, security technology, lighting technology, and the like.

[0007] For example, if a wall or ceiling is covered with plasterboard or similar panels, the subsequent integration of building installation equipment is complex. Furthermore, building installation often requires on-site adjustments to the wall or ceiling paneling, increasing labor and creating mess.

[0008] Against this background, the present disclosure is based on the object of providing a method for producing a building panel with an embedded functional element for building installations, as well as such a building panel, which allows for an aesthetically high-quality, visually unobtrusive design. In particular, the building panel should be easily integrated into a given room design. The building panel should simplify the integration of building installation technology and, in particular, reduce on-site effort. Ideally, the building panel should allow the subsequent installation of building technology with little additional effort.

[0009] According to a first aspect, the present disclosure relates to a method for producing a building panel with an embedded functional element for building installation, comprising the following steps: Providing a carrier plate having a front side and a back side, the carrier plate having a thickness between the front side and the back side, Providing a functional element in the form of a profile piece, machining the support plate from the rear side to produce a receiving profile for the profile piece, wherein the receiving profile extends from the rear side to the front side and ends at least partially in front of the front side, so that a thin-walled wall section remains in front of the profile piece, Inserting the profile piece into the receiving profile of the carrier plate, and Joining the profile piece to the carrier plate, in particular material-to-material joining by means of gluing, wherein the profile piece provides a recess in cross-section and is open at least in sections on the front side, and wherein the carrier plate covers the profile piece on the front side, so that the profile piece is (initially) inaccessible on the front side.

[0010] In this way, a visually appealing, integrated design can be created. The result is a minimalist ("clean") design. The time required to provide such an embedded functional element is significantly reduced compared to subsequent integration into existing structures. The disclosed concept is particularly suitable for use in drywall construction with plasterboard and similar panels. The profile piece is designed, for example, as an extruded profile based on an aluminum alloy. Plastic profiles are also conceivable. The profile piece is, for example, a rail produced using an extrusion process.

[0011] During the production of the carrier plate, an intermediate state can initially be created in which the recess in the profile piece is not yet accessible from the front. This is possible, for example, if the thin-walled wall section initially remains in front of the profile piece. In this state, the carrier plate can be installed, filled, painted, and, if necessary, wallpapered. It is still possible to provide access to the recess later by opening the thin-walled wall section.

[0012] In this way, a wide variety of building technology can be prepared, allowing for subsequent integration with minimal effort if necessary. This could involve, for example, the retrofitting of certain lighting sources and / or the retrofitting of a room's air conditioning. If the necessary precautions have already been taken, ideally no complex drywall work is required. Even if access to the recess is subsequently created, only a small slit is usually visible.

[0013] Joining includes, for example, joining by means of adhesive bonding. The residual wall thickness of the thin-walled wall section is, for example, less than 1.0 mm. In one exemplary embodiment, the residual wall thickness is less than 0.5 mm. In one exemplary embodiment, the residual wall thickness is approximately 0.3 mm.

[0014] The recess provided by the profile piece can also be referred to as a groove. Once the thin-walled wall section in front of the profile piece has been removed, the groove is accessible from the front.

[0015] The functional element embedded in the carrier plate is at least temporarily concealed or hidden from view at the front, so that in this state, the functional element is invisible from the front. The functional element can be used as part of the building's installation. This includes, for example, electrical installations, air conditioning, ventilation, heating, lighting, information transmission, sensor technology, and the like.

[0016] Depending on the volume required by the recess, the profile piece can protrude from the back of the support plate. This is often unproblematic with suspended ceilings and similar applications, as there is sufficient installation space on the back of the support plate.

[0017] The functional element serves, for example, as a lighting support with an integrated power supply. However, the functional element can also serve as a support for smart home components, sensors, and similar devices. The functional element can therefore be used to accommodate installation components for building installations. However, the functional element can also be an integral part of the building's technology, for example, as part of a flow channel.

[0018] According to an exemplary embodiment, the method further comprises the following step: removing at least a portion of the thin-walled wall section after the joining step, so that the profile piece becomes accessible at the front. In this way, an access slot can be created along the longitudinal extent of the profile piece. The thin-walled wall section is removed to provide access to the recess. This can be done even if the carrier plate has been coated with paint, wallpapered, or similarly treated on its front side.

[0019] According to a further exemplary embodiment, the step of removing at least part of the wall section comprises pulling out a strip inserted into the profile piece, wherein the strip at least partially removes the remaining wall section upon withdrawal. The strip can be referred to, for example, as a perforation strip. The strip is adapted, for example, to a width of the slot in order to expose it across its full width. The strip itself serves as a tool for removing the thin-walled wall section.

[0020] According to another exemplary embodiment, the step of removing at least part of the wall section comprises separating the wall section with a cutting tool that engages the support plate from the outside at the front. The cutting tool can be a knife, for example. For example, the cutting tool is designed as a double knife with parallel blades, the spacing of which is adapted to the width of the access slot. For example, the cutting tool is a milling cutter whose working width is adapted to the width of the access slot.

[0021] According to a further aspect, the present disclosure relates to a building panel with an embedded functional element for building installation, comprising: a carrier plate with a front side and a back side, wherein the carrier plate has a thickness between the front side and the back side, a functional element in the form of a profile piece, wherein the profile piece is inserted into a receiving profile produced by machining the carrier plate from the back side and is joined there to the carrier plate, wherein the receiving profile extends from the back side to the front side and ends at least in sections in front of the front side, so that a thin-walled wall section remains in front of the profile piece, wherein the profile piece provides a recess in cross-section and is open at least in sections on the front side, and whereby the support plate covers the profile piece at the front, so that the profile piece at the front is (initially) inaccessible.

[0022] Such a construction board can be used flexibly and, for example, installed in drywall construction. Because the functional element is already integrated, complex post-processing is eliminated. This simplifies the installation of building services and equipment for the building's installation.

[0023] According to another exemplary embodiment, the carrier plate is a plasterboard that can be mounted on a wall or ceiling together with other plasterboards to provide the embedded functional element there. In this way, large-area cladding (wall cladding, ceiling cladding) can be created that at least partially provide the desired functional elements.

[0024] According to another exemplary embodiment, the profile piece has lateral support legs on the rear side of the support plate, which are recessed into the receiving profile. According to another exemplary embodiment, this results in a flat rear side of the support plate, at least in the area of ​​the lateral support legs. The support legs increase the load-bearing capacity and stability of the building board in the area of ​​the functional element.

[0025] According to a further exemplary embodiment, at least one support band, particularly designed as a fabric band, is attached to the back of the support plate, which at least partially covers the profile piece and at least one section of the support plate adjacent to the profile piece. This further increases the load-bearing capacity and stability of the building board in the area of ​​the functional element.

[0026] According to a further exemplary embodiment, the profile piece is a support rail for receiving at least one electrical consumer, which can be mounted non-positively and / or positively on the profile piece, wherein the electrical The consumer is, in particular, a light, a turbomachine, and / or an actuator for flow control. Such components can be easily retrofitted because the support plate is already provided with the profile piece.

[0027] The luminaire can be fully embedded into the recess provided by the profile piece. This creates an integrated design. However, it is also conceivable to insert a luminaire support into the recess in the profile piece and secure it there.

[0028] According to another exemplary embodiment, the electrical load comprises a sensor and / or a signal generator. This may be, for example, a smoke detector, a smart home sensor, a siren, a doorbell, or the like. Sensors may, for example, measure temperature, humidity, brightness, smoke development, CO2 content, and the like. Sensors may also include cameras and / or microphones.

[0029] According to a further exemplary embodiment, at least one supply line for supplying the electrical load is embedded in the profile piece, wherein the at least one supply line is in particular a component of an insert inserted into the profile piece or is integrated directly into the profile piece. The supply line can, for example, be designed as a cable strip that can be inserted into the profile piece. In this way, the effort required to integrate loads is further reduced. For example, lights can be subsequently arranged at any position along the longitudinal extent of the profile piece and supplied with power there. Likewise, the supply line can also be designed as a signal line and used for control and / or information exchange.

[0030] According to a further exemplary embodiment, the profile piece is a component of a flow channel, in particular for air guidance. In this way, for example, ventilation, air conditioning, heating and / or cooling systems can be implemented. The flow channel is at least already formed in sections in the building board, so that subsequent, flexible installation is significantly simplified.

[0031] According to another exemplary embodiment, the profile piece is open at least partially at the rear to allow coupling to a connecting piece. In this way, the profile piece can provide an interface to a conventional hose or pipe piece.

[0032] According to a further exemplary embodiment, the profile piece can be coupled at the front to a closing part, which can be inserted into the recess to delimit the flow channel in the direction of the front. In other words, the flow channel can initially be completely covered by the thin-walled wall section. When the thin-walled wall section is removed, the recess in the profile piece is opened. A closing part can then be inserted to close the flow channel (in cross-section). The closing part can, for example, be held in the profile piece in a form-fitting and / or force-fitting manner. For example, the closing part has a U-shaped profile, the two legs of which on the right and left ensure the fixation of the closing part in the profile piece.

[0033] According to another exemplary embodiment, the end part is closed toward the front to form a flow channel with a closed cross-section. According to another exemplary embodiment, the end part is open toward the front to form an air outlet or air inlet. In this way, the course of the flow channel and the position of any outlets can be determined. The end part can also be partially open and partially closed to position the opening in a targeted manner.

[0034] According to a further exemplary embodiment, the flow channel accommodates a turbomachine, in particular an axially acting turbomachine, whose rotational axis is parallel to the longitudinal extent of the profile piece. In this way, the flow along the flow channel can be actively influenced. The turbomachine (fan or the like) can have a longitudinal extent along their rotational axis that are significantly larger than the dimensions of the cross-section of the flow channel. In this way, the disturbance machine is favorably adapted to the design of the flow channel. Furthermore, the disturbance machine can be positioned anywhere or almost anywhere along the flow channel. At least according to exemplary embodiments, the flow channel does not require any thickening or widening in the area of ​​the turbomachine. The turbomachine's energy supply can be provided via a supply line integrated into the profile piece.

[0035] According to another exemplary embodiment, the flow channel accommodates an actuator for flow guidance, in particular for adjusting a ventilation grille to control the fluid flow. In this way, the fluid flow along the flow channel can be influenced. This can affect the opening and closing of certain paths. It can also affect the position of adjustable grilles (louvres) of openings or the like. Even with an actuator placed along the flow channel, the power supply can be provided via a supply line integrated into the profile piece.

[0036] According to another exemplary embodiment, the flow channel occupies a portion of the cross-section of the profile piece, with an adjacent portion serving to accommodate at least one electrical load. In other words, the profile piece as a whole can provide a cross-section that allows both the formation of the flow channel and the accommodation of an electrical load or the like. In other words, a closure part can be provided for closing the flow channel, which in turn accommodates an electrical load, sensor, or the like.

[0037] According to a further exemplary embodiment, the profile piece extends along a flat side of the support plate along a closed path, wherein a separation can be created along the closed path of the profile piece in order to provide a section of the support plate as a closable cover or closable flap. In this way, the building board can, for example, provide an inspection opening or an inspection cover, whereby this can initially be done invisibly on the front side of the support plate. If, for example, If access is required for maintenance or repair purposes, the integrated inspection opening can be exposed by removing the thin-walled wall section in front of the profile piece. This allows the separation to be exposed and made usable.

[0038] According to another exemplary embodiment, the profile piece is designed in two parts, with the profile piece forming an inner frame and an outer frame, which are particularly movable relative to one another. In other words, according to this embodiment, the recess in the cross-section of the profile piece is open toward both the front and the back.

[0039] According to a further exemplary embodiment, the profile piece has a motion guide for the relative movement between the inner frame and the outer frame, in particular at least one hinge that couples the inner frame and the outer frame. The hinge can be integrated invisibly or almost invisibly into the building panel, at least until the thin-walled wall section is exposed.

[0040] According to another exemplary embodiment, the profile piece has at least one locking mechanism for securing the cutout of the support plate in a closed position. Such elements can also be integrated into the building plate in an invisible or nearly invisible manner.

[0041] According to a further exemplary embodiment, the profile piece has, in addition to the recess, at least one fitting recess extending at least partially parallel to the recess. Two profile pieces facing each other are aligned and connected to each other by inserting a connecting pin into the at least one fitting recess of the two profile pieces. In this way, several building panels can be positioned with high precision relative to each other. According to a further exemplary embodiment, the connecting pieces are conical in design, at least in sections.

[0042] According to another exemplary embodiment, the profile piece extends along a curved path, with the end faces of the profile piece being offset from one another, in particular by 90°. In this way, the functional element can extend over several plates and also along a curved path.

[0043] According to another exemplary embodiment, the profile piece extends along a self-contained path, in particular along a circle or oval. In this way, round fixtures can be realized. For example, the profile piece can be a support for a recessed light, which is integrated into the support plate as unobtrusively as possible. The profile piece can be ring-shaped or disc-shaped. The profile piece can initially be integrated invisibly (at the front). The profile piece can also be used to form a round flap or lid.

[0044] It is understood that the features of the disclosure mentioned above and those to be explained below can be used not only in the combination specified in each case, but also in other combinations or on their own, without departing from the scope of the present disclosure.

[0046] Fig. 1 illustrates a partial view of an end face of a building board 10 comprising a carrier board 12 and a profile piece 14 integrated therein. The building board is designed, for example, as a plasterboard. In its cross-section shown in the view according to Fig. 1, the profile piece 14 provides a recess 16 that is accessible via an access slot 18. The profile piece 14 can be integrated into the carrier board 12 to provide expanded functions there, particularly for building installation purposes. This is illustrated in more detail with reference to Figures 2-6.

[0047] Fig. 2 illustrates the carrier plate 12 in an unmachined state. The carrier plate 12 has a front side 20 and a back side 22. Between the front side 20 and the back side 22, the carrier plate 12 has a thickness 26. Fig. 3 illustrates a state in which a receiving profile 24 is introduced into the carrier plate 12. The receiving profile 24 can be produced, for example, by milling. According to exemplary embodiments, the receiving profile 24 initially extends not completely through the carrier plate 12. In particular, a thin-walled wall section 28 remains on the front side 20.

[0048] Fig. 4 illustrates a joining process for connecting the carrier plate 12 to the profile piece 14. For this purpose, in the exemplary embodiment, an adhesive layer 34 is applied to at least some of the contact surfaces between the profile piece 14 and the carrier plate 12 or its receiving profile 24. In the exemplary embodiment, this also includes lateral support legs 30 of the profile piece 14, which enlarge the support surface and joining surface. Fig. 4 further shows that, in the exemplary embodiment, the profile piece 14 provides two fitting recesses 32 in addition to the recess 16, which allow for a highly precise connection of several building boards 10 with integrated profile pieces 14.

[0049] Fig. 5 illustrates the joined state in which the profile piece 14 and the support plate 12 are firmly bonded. However, in the state shown in Fig. 5, the recess 16 within the profile piece 14 is still closed by the thin-walled wall section 28. In this state, the building board 10 can be processed on its front side 20 in a known manner. This includes, for example, coating with paint or wallpaper.

[0050] Fig. 5 further illustrates that optional support bands 42 can be used to additionally secure and strengthen the assembly of the carrier plate 12 and the profile piece 14 on the rear side 22. The support bands 42 are, for example, fabric tape that can be glued to the rear side 22 of the carrier plate 12 and, if necessary, to the profile piece 14. In the exemplary embodiment according to Fig. 5, the width of the support bands 42 covers the support legs 30 of the profile piece 14 as well as adjacent areas of the rear side 22 of the carrier plate 12.

[0051] Fig. 5 further shows that even in this state, further functional elements can be incorporated into the profile piece 14. In the exemplary embodiment, two cable bands 36 are arranged on opposite sides (for example, right and left) of the profile piece 14 in order to connect conductors 38 for power supply and / or to provide information exchange. However, these functional elements are initially inaccessible in the state shown in Fig. 5.

[0052] Fig. 6 shows that the recess 16 can be exposed as needed by removing the thin-walled wall section 28 in front of the profile piece 14 or in front of the access slot 18 (see Fig. 1). In Fig. 6, a double arrow labeled 52 illustrates this process. The wall section 28 can be separated, for example, using a band 50 that is inserted into the recess 16 in the profile piece 14. The band 50 can be pulled out at the front side 20 (see the arrow labeled 52), whereby the thin-walled wall section 28 is separated. It is understood that the wall section 28 can also be opened in another way, for example using a separate cutting tool. The cutting tool is, for example, a milling cutter, a knife, or a double knife with parallel, spaced-apart blades that are adapted to the width of the access slot 18.

[0053] Fig. 6 further illustrates that the profile piece 16 can protrude beyond the support plate 12 at the rear side 22. A corresponding projection is designated 46 in Fig. 6. In this way, the recess 16 in the profile piece 14 can provide a larger interior space.

[0054] Fig. 7 illustrates a state in which an installation part 60 is inserted into the recess 16 and secured (latched or locked) there. For example, the installation part 60 is an electrical consumer (light or the like). For example, the profile piece 14 provides locking sections 56, 58 in the recess 16, which allow for a positive reception and locking of the installation parts 60. The installation part 60 is inserted into the recess 16 with a housing 62.

[0055] Fig. 7 schematically shows a locking device designated 66, which can engage the latching portion 56 to secure the installation part 60 in the recess 16. Furthermore, the installation part 60 has contacts 70, which engage at least some of the (electrical) conductors 38 of the cable ties 36 within the recess 16. In this way, the installation part 60 can be supplied with energy, for example, with direct current, alternating current, or three-phase current. Coupling to one or more of the conductors 38 for the purpose of information transmission is also conceivable.

[0056] Fig. 6 also schematically shows a rod, designated 72, which extends through the housing 62 of the installation part 60. A curved double arrow, designated 74, illustrates a movement of the rod 72. The rod 72 can be used, for example, to pivot the locking mechanism 66 in order to arrange and secure the installation part 60 on the profile piece 14 or in its recess 16. It is understood that other fastening and positional securing methods are also conceivable.

[0057] Fig. 8 illustrates, using a perspective view, a state in which the cable ties 36 with the conductors 38 are designed as inserts and have not yet been inserted into the recess 16 of the profile piece 14. It is conceivable to provide the profile piece 14 with cable ties 36 (ex works), so that no additional installation work is required. However, it is also conceivable to subsequently insert one or more cable ties 36 into the recess 16 when the access slot 18 to the recess 16 is opened. In the embodiment according to Fig. 8, one or more seats 40 for cable ties 36 are formed within the recess 16.

[0058] Fig. 9 illustrates a design in which a light 80 is inserted into the building panel 10 comprising the profile piece 14. Fig. 10 illustrates a design in which a light 82 is inserted into the building panel 10 comprising the profile piece 14. As already described above, contact can be made there within the recess 16 for the purposes of power supply and control. In Fig. 9, the light 80 is completely accommodated within the recess 16. In Fig. 10, the light 82 protrudes from the recess 16 at the front side 20.

[0059] The profile pieces 114 shown in Fig. 9 and Fig. 10 can basically have a straight extension of the cross-section shown, whereby straight profile rails. However, an extension along a curved path (arcs) or even an extension along a closed path (circle, oval) is also conceivable. A rotationally symmetrical design around a respective central axis is also conceivable, resulting in a pot-like or plate-like design.

[0060] Figures 11-13 illustrate a further embodiment of a building panel, designated overall by 110, which comprises a profile piece 114 integrated into a carrier plate 112. Production can be carried out analogously to the steps illustrated in Figures 2-6, so reference is made thereto to avoid repetition. In the exemplary embodiment, the profile piece 114 is a circumferential, closed profile piece; compare the schematic plan view according to Fig. 13. The closed profile piece 114 can be rectangular, optionally with rounded edges as in Fig. 13. However, the closed profile piece can also extend along a circular path or an oval.

[0061] In the exemplary embodiment, the profile piece 114 is designed in two parts; the recess 116 extends completely between the front and rear sides through the profile piece 114. This illustration in Fig. 11 shows a state in which the thin-walled wall section 128 in front of the profile piece 114 has not been removed or opened. The profile piece 130 is initially concealed (invisible) at the front. The profile piece 114 forms a cover 150 integrated into the carrier plate 112.

[0062] Due to the two-part design, the profile piece 114 provides an inner frame 154 and an outer frame 152, each forming a support leg 130 on the rear side. If the thin-walled wall section 128 in front of the recess 116 is now opened, the inner frame 154 can be removed from the outer frame 152, at least a relative movement between the inner frame 154 and the outer frame 152 is possible. The outer frame 152 remains at an edge 156 of the support plate 112. In this way, a cutout 158 ​​of the support plate 112 is detached from the edge 156. The cutout 158 ​​and the inner frame 154 form the cover 150. The detached state is shown in Fig. 12. By way of example, the profile piece 114 in the inner frame 154 or the outer frame 152 has at least one circumferential Seal 166 which seals the (also circumferential) recess 116 between the inner frame 154 and the outer frame 152.

[0063] Based on Figures 11-13, Figures 14 and 15 illustrate alternative designs of a building panel 110 provided with a cover 150. In the design shown in Figures 11-13, the cover 150 there is completely removable. The cover 150 shown in Figures 14 and 15 is connected to the building panel 110 via a hinge 170 and can be pivoted for opening and closing; compare a curved double-headed arrow designated 172. In the exemplary embodiment, the hinge 170 couples the inner frame 154 to the outer frame 152, wherein the inner frame 154 and the outer frame 152 can be pivoted relative to one another. In addition, Figure 15 illustrates a design in which the closed state of the cover 150 can be locked with a locking element 176. A double arrow designated 178 illustrates an actuation of the locking element 176 for locking and unlocking the cover 150.

[0064] Figures 16-21 illustrate embodiments of a building panel 210 in which the profile piece 214 integrated into the respective support plate 212 can provide a flow channel 262 in the recess 216. Fig. 16 shows that the profile piece 214 protrudes significantly beyond the rear side of the support plate 212; see the double arrow 246 for illustrating the projection. In other words, the height of the profile piece 214 is several times the thickness of the support plate 212. For example, the height of the profile piece 214 corresponds to five to ten times the thickness of the support plate 212. This is not to be understood as limiting.

[0065] The production of the building panel 210 can be carried out analogously to the steps illustrated in Figures 2-6, so that reference is made to them to avoid repetition. In other words, the profile piece 214 can initially be integrated invisibly (on the front side) into the carrier plate 212. The profile piece 214 has legs 230 with which it rests against the carrier plate 212 on the rear side. In the exemplary embodiment, fitting recesses 232 for positioning and aligning two building panels 210 / profile pieces 214 to be coupled together are arranged adjacent to the recess 216.

[0066] Arranged in the recess 216 are a plurality of locking sections 256, which serve for mounting and fastening installation parts in the recess 216. Fig. 16 shows such an installation part in the form of a closure part 260 spaced apart from the building board 210. The closure part 260 has a U-shaped cross-section with two legs 266. Fig. 17 shows a state in which the closure part 260 is inserted into the recess 216. The legs 266 are locked to the locking sections 256. In this way, a flow channel 262 is defined in the recess 216. The closure part 260 closes an access slot of the recess 216.

[0067] In the exemplary embodiment, the end piece 260 ensures a flush finish on the front side of the building panel 210. According to the design shown in Fig. 16, the end piece 260 is closed at the base of the U-shaped cross-section. According to the design shown in Fig. 17, the end piece 260 there is provided with an air outlet or inlet 268 at the base of the U-shaped cross-section.

[0068] Figures 18-21 also show embodiments of the building plate 210 with an integrated flow channel 262. However, in contrast to the embodiments according to Fig. 16 and Fig. 17, an installation part serving merely as a closing part 260 is not installed. Instead, installation parts 270, 280, 290, 300 are installed, which, on the one hand, define the flow channel 262, but, on the other hand, provide additional functions.

[0069] In Fig. 18, an installation part 270 with a flow machine 272 (fan or the like) is inserted into the recess 216. In Fig. 19, an installation part 280 with an actuator 282 in the form of a valve or flap 282 is inserted into the recess 216. The flow machine 272 can be used to generate or maintain a flow through the flow channel 262. The actuator 282 can be used to control the flow through the flow channel 262.

[0070] In Fig. 20, an installation part 290 in the form of a lamp 292 is inserted into the recess 216. In Fig. 21, an installation part 300 with at least one Sensor 302 is inserted into the recess 216. In other words, the recess 216 can serve partly to form the flow channel 262 and partly to accommodate installation parts 270, 280, 290, 300.

[0071] Fig. 22 illustrates, using a perspective, partially sectioned view, a further embodiment of a building panel 210 with a profile piece 214 integrated into a support plate 212. The profile piece 214 accommodates, at least in sections, a flow channel 262. At the front side, an installation part in the form of a closing part 260 is inserted into the profile piece 214. The closing part 260 can be closed or open towards the front side.

[0072] An opening 212 is provided in the rear side of the profile piece 214. The opening 212 serves to accommodate a connection box 310, which can be connected to the opening 312 via a connection piece 314. In the exemplary embodiment, the connection box 310 has a connection piece 316 for receiving a hose or pipe for flow guidance purposes. In this way, the flow channel 262 can be fluidically connected to other flow channels, compare a flow path designated 318.

[0073] Fig. 23 illustrates, using a schematic representation, an arrangement 350 with a plurality of building panels 210 (210-1, 210-2, 210-3) with profile pieces 214 that are integrated into respective support plates 212. The profile pieces 214 in the plan view shown can be straight or curved. In this way, deflections are possible. The alignment and connection of the building panels 210 or the profile pieces 214 can be achieved at the respective end faces of the profile pieces 214 by connectors 352 in the form of connecting pins or the like. The connectors 352 can, for example, be inserted into suitable fitting recesses 232 (see Fig. 16) of the profile pieces 214 in order to align mutually facing end faces of two profile pieces 214 with one another.

[0074] A flow channel 262 extends along the exemplary building panels 201-1, 210-2, 210-3, which is formed by profile pieces 214 and suitable Installation parts are defined. For example, a terminal box 310 with connecting pieces 316 is arranged in the construction panel 210-1. Furthermore, an installation part with a turbomachine (fan) 272 is integrated, wherein the turbomachine 272 is designed as an axial fan for space reasons. Thus, the turbomachine 272 can be conveniently integrated into the profile piece 214 in the manner already described. Furthermore, an installation part in the form of a light 292 is integrated into the profile piece 214 of the construction panel 210-1.

[0075] In the case of the building plate 210-3, for example, an actuator 282 in the form of an adjustable ventilation grille or an adjustable flap is integrated into the profile piece 214 there. The actuator 282 is adapted to the design of the profile piece 214 and the recess provided by the profile piece 214. Furthermore, an installation part in the form of a sensor 302 is integrated into the profile piece 214 of the building plate 210-3.

[0076] The building plate 210-2 has a profile piece 214 with a 90° deflection. In this way, the flow channel 262 can be conveniently deflected between the mutually orthogonally oriented profile pieces 214 of the building plates 210-1 and 210-3.

[0077] The above explanations in conjunction with Figures 1-23 illustrate that, with building panels according to the disclosure, a wide variety of functional elements for building installations can be integrated into carrier panels in a visually appealing manner, particularly in plasterboard panels that can be processed using drywall construction. One advantage according to the disclosure is that the integration of the functional components can initially be invisible or almost invisible on the front. However, if the functional component is intended to be used for building installations / building services, access can be created in a simple manner. In exemplary embodiments, the functional components (profile pieces) can provide an integrated power supply that supplies electrical consumers with power as needed, without the need to lay additional cables.
