Description

[0001] The invention relates to a panel for dry interior construction, which has a sandwich construction, according to claim 1, and to a panel system in which these panels are used.

[0002] Conventional drywall panels for the construction of non-load-bearing partition walls are cut to size and installed on site. Typically, plasterboard is used for this purpose. These panels consist of a sheet of plaster covered on both main surfaces with a suitably robust paper or paper-like element. The surrounding surfaces surrounding the plasterboard, which connect the two main surfaces, are free of such coverings. These panels are screwed onto steel profiles that are mounted to the floor, ceiling, and intermediate studs, ultimately forming a wall in which the steel structure is concealed by the plasterboard. The space between them is either empty or filled with some kind of insulating material.In order to increase fire resistance, two panels can be mounted flat against each other on one side / both sides of the steel structure.

[0003] The work required is time-consuming and therefore blocks the construction site for extended periods. It also creates waste that can potentially cause problems on the construction site, such as small pieces of steel scrap or the dust generated when cutting the plasterboard. While the fire-retardant properties are satisfactory, the acoustic insulation is weak, and the space required is too small compared to the insulation effect.

[0004] CN209990012U discloses a system of fire-resistant gypsum boards in which the gypsum walls are bonded on one side to U-shaped metal plates. These gypsum composite boards exhibit fire-resistant properties, but require a relatively large installation space and are susceptible to moisture penetration.

[0005] DE202017104561U1 discloses a partition wall system, primarily for interior spaces in office buildings, exhibition halls, and residential buildings with load-bearing skeletons. Partition walls according to this document provide sound insulation, but also require a lot of installation space and are susceptible to moisture penetration.

[0006] Similarly, JP2020026674A and DE19960535A1 also describe partition wall systems for improved sound absorption, which also require a relatively large amount of installation space and are susceptible to moisture penetration.

[0007] There is therefore a need for a panel for dry interior construction that has the most compact installation space possible and can be adapted to the intended use so that it can be sealed against the penetration of moisture and, if necessary, still has good fire-retardant properties.

[0008] According to the invention, the desired objectives are achieved by a panel for dry interior construction having the features specified in the characterizing part of claim 1. In other words, a conventional drywall panel, preferably made of gypsum fiber, is used as the panel core and is provided on each of its sides with a moisture-resistant, preferably metallic, cover panel, which is optionally coated, painted, or foiled, with an intermediate filling already glued in the factory and preferably manufactured to fit precisely, or cut to fit precisely on site.

[0009] This drywall panel for interior finishing has a pre-defined underside. A groove is provided on this underside to accommodate a floor profile that is attached to the floor and positions the panel. If the drywall panel is intended to butt against another drywall panel along a vertical joint, it also has a groove on this side surface, which does not necessarily have the same geometric dimensions as the groove on the underside of the panel. The panel is finally secured by a ceiling profile and, if necessary, a side profile.

[0010] If the panel for dry interior construction is intended to be installed in a wet room or if the ingress of moisture and / or water is to be feared, the panel for dry interior construction must have a filling of moisture-resistant material at least in the lower area (the area closest to the floor) where such ingress is feared (this can therefore also include the entire panel). The joints that the panel has in the floor area, regardless of whether they are horizontal or vertical, are preferably provided with a hydromechanically insulating compound so that there is no risk of rising damp. In addition, a second sealing layer can, but does not have to, be installed between the hydromechanically insulating compound and the panel core using a sealing tape and / or sealing profile.

[0011] If a gypsum fibreboard is used as the core of the board, it is preferably glued to the cover boards, but it is also possible, for example, to use the cover boards as permanent formwork and to pour in the filling and allow it to harden, which also results in a permanent connection to the cover boards.

[0012] In this way, on the construction site it is only necessary to attach the floor profile, the ceiling profile explained below, and the profiles on the wall where the partition wall to be erected abuts the wall specified on the construction site, and then to insert the panels without any further fastening means and thus without damaging the surface of the panels, which, as also explained below, is done by pushing or lifting.

[0013] This results in a finished partition wall with excellent fire-retardant, acoustically dampening and moisture-resistant properties, which can be designed optically according to the customer's wishes and can also be finished with different surface coverings on one or both sides (tiles, etc.). If necessary, it can also be dimensioned or constructed differently in terms of its thickness (of course only from partition wall to partition wall) and can therefore be provided with different insulating properties.

[0014] The individual wall panels can be made of different materials and can be combined with each other if they have the same thickness, so that glass in a sandwich construction, i.e. made of VSG (laminated safety glass) or ESG (toughened safety glass) with a groove designed according to the application, i.e. on 3 sides or only on the bottom side, can be used in combination with panels according to the invention for dry interior construction.

[0015] The major advantage over the state-of-the-art, even in the version without seals, is that the formwork on both sides with cover panels saves a significant amount of installation space compared to conventional systems, while still achieving surprisingly significant improvements in sound insulation. In particular, the improved properties allow for a significant reduction in the thickness of the partition wall compared to the state-of-the-art, significantly increasing the usable space of the apartment or office, or minimizing the area to be built (requirement for floor sealing per apartment).

[0016] These walls, which are significantly thinner than the current state of the art, can be easily dismantled at any time and reused in a resource-efficient manner, as they always stand on the finished screed (or raised floor, etc., thus allowing the area of ​​several rooms to be covered with screed, etc.) or on the finished floor. Compared to conventional plasterboard stud walls, they require minimal, complex disposal.

[0017] Another major advantage over the state of the art in the preferred embodiment of the panel for dry interior construction is the possibility of shielding it hydromechanically and thereby preventing in particular the penetration of water and, subsequently, the swelling of classic drywall panels.

[0018] The invention is explained in more detail below with reference to the drawing, which shows: the Fig. 1a and bpurely schematic vertical sections through preferred embodiments of the panels according to the invention for dry interior construction, the Fig. 2a and b purely schematic horizontal section through two adjoining panels according to the invention for dry interior construction, the Fig. 3 a floor profile usable for a panel system according to the invention, in a longitudinal ( Fig. 3a ) and two cross sections ( Fig. 3b & c ) and a perspective view ( Fig. 3d ), the Fig. 4 a purely schematic section through a ceiling profile that can be used for the panel system according to the invention, the Fig. 5 a purely schematic section through a T-joint profile that can be used for the panel system according to the invention, the Fig. 6 a purely schematic section through a 90° corner profile suitable for the panel system according to the invention, the Fig. 7a and btwo purely schematic sections through two butt joint profiles suitable for the panel system according to the invention for the application according to Fig. 2a or Fig.2b , the Fig. 8 a purely schematic section through a finishing profile that can be used for the panel system according to the invention, the Fig. 9 a purely schematic section through a 2-part wall connection profile that can be used for the panel system according to the invention, the Fig. 10 a purely schematic section through a frame profile that can be used for the panel system according to the invention and the Fig. 11 a floor plan section as an example a purely schematic representation of the system used

[0019] The Fig. 1ashows, in a purely schematic way, a vertical section through a panel 1 according to the invention for dry interior construction, which in the illustrated embodiment is equipped for use in a wet room. In principle, the panel 1 consists of a filling 2 (the panel core) and is provided on both sides with moisture-resistant cover panels 3, 4. The cover panels 3, 4 can, but do not have to, have the same mechanical and geometric properties. Furthermore, the cover panels 3, 4 can be made of a wide variety of moisture-resistant materials, such as plastic and metal. The cover panels 3, 4 are preferably made of metallic material in order to achieve fire-retardant properties in addition to moisture resistance. Steel or aluminum in different material thicknesses, preferably between 0.4 mm and 1 mm, is particularly preferably used.In special cases where only imperceptible mechanical stress is expected, thinner cover panels can be used; in cases of extreme stress, thicker ones are used. The surfaces can be painted, powder-coated, foil-coated, veneered, wallpapered, or left untreated, and can also be covered with ceramic wall coverings. In the example shown, the panel 1 has a groove 6 on its underside 5, which is suitable for accommodating a web 7 of a floor profile 8.

[0020] These elements are provided for all panels 1 according to the invention. For installation in wet rooms, the following elements are also used: Fig. 1The following features are apparent: In the lower area, instead of the panel core 2, a moisture-resistant filling 2' is attached. Preferably, at least in this area, between the filling 2' and the panel core 2 in the area between the cover panels 3, 4, a further, internal seal 9 is provided. In the illustrated embodiment, this internal seal 9 is shown and formed above the moisture-resistant filling 2'. Furthermore, the floor profile 8 is not attached to the floor 11 directly, but via a moisture-repellent (hydrophobic) and moisture-insulating intermediate layer 10, which is preferably an easy-to-apply hydrophobic swelling paste, in order to avoid direct contact with the floor as much as possible. This also largely prevents the penetration of moisture through capillaries.

[0021] In Fig. 1The groove 6 is shown significantly deeper than the height of the web 7, but it need not be that large. It is important to avoid the end of the web 7 touching the bottom of the groove 6, as this can lead to mechanical problems. Transferring the weight of the panel 1 via the metal cover plates 3, 4 to the base profile 8 is generally preferred. Therefore, the end of the web 7 and the bottom of the groove 6 should at most touch when installed.

[0022] The inner seal 9 is preferably made of hydrophobic material such as rubber, silicone rubber, plastic, etc. and has a certain elasticity, which is used during insertion to exert a force-fitting connection and thus a sealing contact against the cover plates 3, 4, the filling 2 as well as the floor profile 8 and / or the filling 2'.

[0023] In the example shown, the filling 2 is bonded to the cover panels 3, 4 by means of an adhesive. However, as already explained, it can also be obtained by pouring it into the formwork. The moisture-resistant filling 2' can also be glued to the cover panels 3, 4, or it can be foamed or cast in, or held in place by elastic prestressing, which ensures the transfer of the weight of the panel 1 to the floor profile 8 via the cover panels 3, 4.

[0024] The Fig. 1b shows a version of panel 1 for dry interior construction analogous to Fig. 1a. The inner seal 9 is replaced by the inner seal 9a. The inner seal 9a adjoins the filling 2 inside the panel and forms two downwardly extending webs, each of which encloses fillings 2' between them and the cover panels 3, 4. There is no filling 2' between the webs, and the groove 6 thus extends vertically upwards from the base profile 8 to the lower edge of the inner seal 9a. The same applies to the top and side areas of panel 1.

[0025] The Fig. 2a shows an example of a horizontal section through a vertical joint between two panels 1 for dry interior construction in the area of ​​their side edges 24, analogous to Fig. 1a. A butt joint profile 18 made of permanently elastic plastic or rubber is used to ensure a flat (aligned) connection of the panels 1. The length of the butt joint profile 18 in the horizontal direction is preferably slightly shorter than the sum L of the depths of the two grooves in order to reliably avoid longitudinal stresses. The vertical extension (normal to the image plane) of the butt joint profile 18 preferably extends from the floor profile 8 (see Fig. 1 ) to the upper edge of the panels 1, whereby division into smaller sections is of course also possible. Whether and in what form the illustrated "barbs" are provided is easily determined by a person skilled in the art, given knowledge of the invention and the respective field of application. The use of the materials mentioned ensures easy separation of the panels in the event of a conversion or replacement.

[0026] It is in Fig. 2aA further, inner seal 9 is also provided. This is a particularly preferred embodiment, but only necessary or recommended in special cases, for example, to protect the neighboring panels in the event of water ingress into one of the panels, so that only the panels damaged by the water need to be replaced. It is therefore also possible, for example, not to provide these seals 9, even if seals are present in the base area of ​​the panels (see Fig. 1a or 1b).

[0027] The Fig. 2b shows an alternative horizontal section through a vertical joint between two panels 1 for dry interior construction in the area of ​​their side edges 24, analogous to Fig. 1b The general statements made in Fig. 2a were also taken for Fig. 2bValidity. It should be noted in particular that due to the different shape of the seal 9a in contrast to the seal 9 made of Fig. 2a or Fig. 1a , a different joint profile 18 can also be used. Here, too, in order to reliably avoid longitudinal stresses, the length of the butt joint profile 18 in the horizontal direction should preferably be somewhat shorter than the sum L of the depths of the two grooves. Theoretically, a combination of the seal 9a made of Fig. 2b with joint profile 18 made of Fig. 2a possible (as well as a combination of the joint profile 18 from Fig. 2b with the seal 9 from Fig. 2a ). The special in Fig. 2b However, the combination shown is particularly advantageous for applications in which the walls must be separated again with minimal effort.

[0028] The Fig. 3a to d shows an embodiment of a soil profile 8 in a longitudinal ( Fig. 3a ) and two cross sections ( Fig. 3b & c) and a perspective view ( Fig. 3d ). The respective sections are marked AA, BB, and CC. The height H of the web 7 is also indicated. Installation to the subfloor or screed is carried out, for example, by screwing, gluing, or using nails. Compensation of construction tolerances can be achieved using supports made of various pressure-resistant materials. The seal against the floor is preferably created using swelling paste 10 (see Fig. 1 ). The dead weight of the panels 1 is statically transferred to the floor profile 8 via the cover plates 3, 4.

[0029] The width of the floor profile 8 preferably corresponds to the thickness of the associated panel(s) 1. However, a slight overhang of the floor profile 8 can be mechanically advantageous, allowing a balance between appearance and safety.

[0030] In the illustrated embodiment, the holes for the fastening elements are shown without their own reference numerals, the height H of the web 7 above the upper, horizontal surface of the floor profile 8 is, as already Fig. 1 described, to be coordinated with the depth of the groove 6 of the panels 1 used in order to prevent vertical forces from being diverted via the web 7. The cross-sectional shape of the web 7 can vary within wide limits, as long as guidance and positioning in the horizontal direction transverse to the longitudinal axis of the floor profile 8 is achieved. The slightly undercut shape shown represents a particularly advantageous embodiment, since a particularly favorable mounting of the panel 1 can be achieved through slight elastic deformation of the filling 2 or 2'.

[0031] The Fig. 4shows a ceiling profile 13 which is well suited for the installation of the panel 1 according to the invention. In the installed state, it is essentially inverted U-shaped and the two legs 14, 15 of the profile 13 are significantly longer than the recess of the panel 1, which is shown schematically in dotted lines and projects into the ceiling profile 13. The projection D is noticeably higher than the height H (see Fig. 3 ) of the web 7 of the floor profile 8. This allows the panel 1 to be threaded from below into the ceiling profile 13 until its upper edge abuts the inside of the bottom of the ceiling profile 13, then pivoted over the floor profile 8 and allowed to slide its groove 6 over the web 7 of the floor profile. This projection D also allows for the accommodation of structural tolerances, so that no statically effective forces are transferred vertically into the panel 1.

[0032] Furthermore, the illustrated variant of the ceiling profile 13 also features various inwardly projecting webs (without reference symbols) that serve to accommodate rubber or plastic profiles 22 or permanently elastic sealing compounds, indicated by faint lines. These can be the same on both sides or, as shown in Fig. 4 shown, can be of varying degrees. These rubber or plastic profiles 22 or permanently elastic sealing compounds hold the panel 1 without contact with the ceiling profile 13, whereby structure-borne sound is not transmitted or is transmitted only with a strong attenuation. To increase sound insulation, these ceiling profiles can be filled more or less densely as required, for example, using foam strips (compression strips or other expanding filling materials). Furthermore, it is possible to replace the ceiling profile with a 2-part wall connection profile, as shown in Fig. 9 represented, to replace, i.e. and / or to use.

[0033] The ceiling profile 13 is attached to the ceiling either directly or, like the floor profile 8 on the floor, via an insulation zone, for example by screwing or gluing or by means of shot nails.

[0034] The Figs. 5 and 6 show horizontal sections through a connecting profile to be laid vertically between two (17) or three (16) panels 1 for a T-joint 16 or for a corner 17, in which webs 7 are designed analogously to the web 7 of the base profile 8, which, despite the different arrangement and possibly different dimensions, have been given the same reference numeral to clarify the analogy. These profiles 16, 17 can either be glued to the panels 1 or simply plugged in. A design of the webs 7 as in the butt joint element 18, i.e. with barbs, is also possible. Plastic with good mechanical properties or aluminum is preferred as the material.

[0035] The Fig. 7a or b shows in section normal to the longitudinal extension examples of a usually band-shaped butt joint element 18, which can be inserted into the vertical grooves of adjacent panels 1 and holds the panels 1 butt to butt with the respective edges of the groove, see Fig. 2a or b. Fig. 7a one in Fig. 2a used butt joint element 18 and Fig. 7b one in Fig. 2b used butt joint element 18. It is advantageous to provide that the width L1, the element width of the butt element 18, is not greater than the combined depth of the two grooves of the adjacent plates 1. The shape and number of Fig. 7a The barbs shown can be varied within wide limits and, for example, replaced by round shapes (similar to O-rings in grooves); all kinds of combinations are possible.

[0036] The Fig. 8shows an example of a wall termination profile 19. This can be glued or simply plugged in. A version of the web as in the butt joint element 18 in Fig. 7 , i.e., with or without barbs, is also possible. Plastic with good mechanical properties or aluminum is preferred.

[0037] The Fig. 9shows an example of a 2-part wall connection profile 14, 21 with the free dimension L to accommodate structural tolerances. Seals 22 are also provided, although these can of course be omitted (workshops, storage rooms, etc.) and do not have to be of the same type. The leg 14 is first attached to the wall / ceiling, then the panel 1 is placed, and finally the click profile 21 is clipped on. To increase sound insulation, these wall connection profiles can be filled more or less tightly as required, for example using foam strips (compression strips or other expanding filler materials). Here, too, it is possible to use a ceiling profile 13 ( Fig. 4 ), which has greater mechanical stability due to its one-piece design.

[0038] The Fig. 10shows an example of a door frame profile 23 for installation in a wall consisting of panels 1 in a horizontal section. The door can be floor-to-ceiling, or provided with a fanlight, or with panel(s) 1 above the lintel (in which case the door frame is constructed from such profiles, cut at a miter). Here, too, seals 22 are provided to frame panel 1; panel 1 is shown here as a typical panel for a dry area only with filling 2, thus without an inner seal 9, 9a, up to the side edge 24 and without groove 6 (which can of course be provided), in order to visually demonstrate this variant, which can of course be used anywhere and on all edges.

[0039] The Fig. 11 shows a schematic top view of an example of a section of a floor plan, showing where the parts and elements shown in the individual figures can be inserted.

[0040] Regarding the materials that can be used, the following should be noted, even though a person skilled in the art of interior design, with knowledge of the invention, does not require such information: A suitable gypsum fiberboard is, for example, the FERMACELL ® board, with a density of 1150±50 kg / m 3 , a water vapor diffusion resistance factor µ=13, a thermal conductivity Δ=0.32 W / mK, and a specific heat capacity c=1.1 kJ / kgK. These are values ​​that other gypsum fiberboards also essentially have and are therefore usable.

[0041] For example, double-sided adhesive tape can be used to bond the gypsum fiberboard to the cover boards; for example, reference is made to the S-4710 MF from ATP.

[0042] Panels made of moisture-resistant materials, such as plastics or metals, can be used as cover panels 3, 4. Due to their flame-retardant properties, particularly preferred versions of the panel 1 according to the invention include cover panels 3, 4 made of aluminum, including various aluminum alloys, particularly aluminum-manganese alloys, or cover panels 3, 4 made of steel. With knowledge of the invention and the requirements for the finished panel 1 and the cover panels 3, 4, a person with specialist training in the field of dry interior construction can easily make their choice.

[0043] For example, swelling pastes or sealing compounds based on polyurethane with a low proportion of free monomeric diisocyanates, such as Sikaflex®< 11FC Purform®< , can be used as the insulating intermediate layer 10. Compounds based on silicones, polysulfides, or hot melts can also be used.

[0044] A two-component polyurethane sealant, such as that used in insulating glass, can be used as a moisture-resistant material for the 2' filling. Reference is made, for example, to POLIVER GP-AC from FENZI.

[0045] The profiles 13, 14, 15, 19, 21 can, independently of one another, be made of aluminum, various aluminum alloys, in particular aluminum-manganese alloys, or plastic.

[0046] The impact element 18 can be made of aluminum, rubber, wood, or plastic, for example.

[0047] The inner seal 9, 9a can be made, for example, of butyl-aluminum composite material or other silicones or other waterproof materials suitable as seal 9, 9a. Suitable sealants are known to the expert.

[0048] The term "classic drywall board," for example in connection with filling 2, refers to a board suitable for drywall construction. Experts typically understand this to mean gypsum fiberboard, wood fiberboard, clay building boards, or similar.

[0049] Just for the sake of completeness, it should be mentioned that these panels are of course also suitable for installing ceiling panels.

[0050] In summary, the main advantage of the invention is to provide panels 1 for dry interior construction that can be installed quickly, easily, and without causing unnecessary mess on construction sites. These panels 1 can be easily threaded into pre-installed floor profiles 8 and secured, for example, using ceiling profiles 13. Due to the special sandwich construction and the possibility of additionally insulating the connecting profiles, good soundproofing properties can be achieved in a very compact installation space. This would require at least two conventional drywall walls installed in parallel with insulation material in between.

[0051] Furthermore, these properties of panel 1 or the panel system can be improved by attaching fire-resistant cover panels 3, 4, preferably made of metal, and an additional, very good flame-retardant effect of the resulting wall can be achieved. One reason for the improved flame-retardant effect is the largely omission of combustible materials such as insulation wool, which can be achieved through the special construction.

[0052] Furthermore, the properties of the panel 1 can be further improved by providing a moisture-resistant filling 2' and, if necessary, an internal seal 9, 9a. In this way, the sides provided with the filling 2' or the internal seal 9, 9a can also be sealed against the penetration of liquid. If this filling 2' or internal seal 9, 9a is provided on all circumferential sides (5, 24, top side without reference numeral) and the cover panels 3, 4 are made of metallic materials, the result is a panel 1 that is optimally sealed against the penetration of liquid, is very well suited for use in wet rooms and also exhibits flame-retardant properties.
