Description

[0001] The invention relates to a modular system for the manufacture of a soundproof wall or soundproof capsule for sound insulation, in particular for secondary noise reduction of noise-generating devices such as heat pumps, generators or compressors, according to the preamble of claim 1 and a sound or noise barrier wall or capsule according to the preamble of claim 13.

[0002] In the field of machine acoustics, there is considerable interest in developing and implementing not only primary noise reduction measures but also secondary sound insulation for generators, compressors, heat pumps, and similar energy conversion machines. Secondary sound insulation is intended to be a structural addition, such as an enclosure, a hood, or a wall, which, independent of the primary structure, significantly reduces the noise level of the energy conversion machine, thus enabling compliance with legal noise limits and protecting local residents. A number of secondary sound insulation solutions are offered on the market by specialist companies, typically tailored to the specific machine. However, there is currently no standardized system available, particularly for DIY projects, designed for a wide variety of machines.

[0003] To reduce the operating noise and airborne sound of an energy conversion machine, DIY solutions for secondary soundproofing are typically using insulation panels, which are cumbersome and time-consuming to install along with other essential building components. Usually, ready-made insulation elements from a hardware store, typically used for ceiling or roof insulation, are purchased. These are then placed inside a self-built enclosure or a prefabricated box, which usually surrounds the energy conversion machine with a larger gap to allow for necessary air circulation for cooling, and mounted on the interior wall. Finding a suitable box with the correct dimensions for the noise-generating device is extremely time-consuming, as it first needs to be researched and located in stores, or alternatively, built from scratch.The insulation panels, manufactured to standard dimensions for roof or ceiling insulation, must first be cut to a suitable size in order to be inserted into the enclosure or box and attached to it.

[0004] The disadvantage of such solutions is that a construction consisting of various components from different manufacturers must first be planned in advance, the components must be purchased via various sales platforms, and then they must be assembled in a time-consuming and complicated process using housing molds or stand constructions, insulation elements and tools such as drills, screws.

[0005] The object of the invention is to provide a simple modular system for the production of a soundproof wall or soundproof enclosure for sound insulation, in particular for the secondary noise reduction of noise-generating devices such as heat pumps, generators, or compressors. The ecological design of this modular system, using sustainable materials, is intended to combine both environmental protection and effective noise and, in particular, sound insulation. The secondary sound insulation is intended to be a weatherproof addition.

[0006] The modular system is also designed to be suitable for creating entire rooms from multiple soundproof walls. Additionally, it should ensure a reduction in airborne noise by completely or partially isolating the noise source, while ensuring the circulation of cooling air through special openings, ducts, or air-permeable materials.

[0007] This problem is solved according to the invention by the features mentioned in claim 1 and claim 13, wherein advantageous further developments of the invention are characterized by the features in the dependent claims.

[0008] An advantageous embodiment of the invention relates to a modular system comprising several modules, including a first group of prefabricated panels, each of which consists of a frame module, one or more infill modules, at least one first and one second cover module, and fastening means or elements, preferably adhesives. Essential to the invention is the following further module or modules from a second group, namely at least one spring module. The at least one spring module serves, firstly, to connect two panels, which are joined end-to-end or longitudinally in a butt-to-end configuration to produce a soundproof wall or soundproof enclosure from the at least two panels.

[0009] The panel, or more precisely the frame module of the panel, has a groove formed on the outside of the frame module, preferably running along the center of the outside, and particularly preferably completely circumferentially. At least one spring module engages in this groove, the engagement depth of which will be described later. The frame module defines a space located on its interior (also called the "framed space" or "interior"). At least one infill module, preferably several infill modules, are inserted into this space, with advantageously enough infill modules being inserted into the interior of the frame module to fill at least three-quarters, and preferably completely, the interior with infill modules. The infill modules are preferably inserted modularly in their longitudinal direction parallel to the longitudinal direction of the frame module and stacked until the preferably entire height of the space is filled.The interior of the frame module is partially, but preferably completely, filled in its internal length, height, and width when the panel is finished. Naturally, the best sound insulation is achieved with complete interior filling.

[0010] Advantageously, the infill modules are flush with the frame module on both the front and back and do not protrude outwards beyond the frame of the frame module. This is the only way to create a flat wall or capsule that is easy to handle during installation. Therefore, each infill module preferably has a width that corresponds to the width of the frame module. This ensures that the front and back surfaces of the infill module are flush with the respective front and back surfaces of the frame module. The at least one first cover module covers the front of the frame module and the front of the at least one infill module completely, preferably over the entire surface, when the first panel is fully installed. Similarly, the at least one second cover module covers the back of the frame module and the back of the at least one infill module completely, preferably over the entire surface, when the first panel is fully installed."Full surface" means that the entire front surface of the panel or the entire rear surface of the panel, as defined in the figures, is covered (no longer visible). Both the first and second cover modules are attached to their respective front or back surfaces of the frame module, either by adhesive or by means of fasteners or elements.

[0011] Alternatively, the width of the at least one filling module can also be less than the width of the frame module, so that an air gap is formed between the at least one filling module and the first and / or second cover plate.

[0012] The modular system preferably comprises a further module from a third group, namely at least one corner module. The corner module has a square base shape, the dimensions of which are at least equal to the width of the prefabricated panel. Due to its square shape, the corner module's height corresponds to the panel's width. A certain width allowance of up to 10 mm is preferred, allowing standardized corner modules to be used with panels with various cover modules. The corner module has at least one groove on one of its surfaces adjacent to a panel, the dimensions and position of which correspond to the groove of a prefabricated panel, so that the panel and the corner module form a stable unit after the grooves of the corner module and the prefabricated panel adjacent to the corner module are connected by means of at least one spring module.Preferably, the corner module has two grooves on two of its surfaces adjacent to each of two panels, which are to be connected at a corner or lengthwise by means of the corner module. These grooves of the corner module also correspond in their dimensions and position to the groove of the prefabricated panels, so that after the grooves of the corner module and two prefabricated panels adjacent to the corner module are connected by means of at least one tongue module each, both the panels and the corner module form a stable unit. If the corner module connects two panels at a corner, the grooves in the corner module are expediently formed on two adjacent surfaces of the corner module, preferably one groove on the wide side and one on the tall side of the corner module. In the other case, if the corner module connects two panels lengthwise, the grooves are formed on opposite surfaces of the corner module, preferably on the wide sides or the tall sides.The corner module is a support element that provides high stability to a wall or the vertical walls of a capsule, formed from at least two panels, in its upright position. A corner module with at least two grooves allows for the construction of a corner with two walls at a 90° angle. However, other cross-sectional contours of the corner modules are also possible, such as triangular, pentagonal, or hexagonal, which allow for other spatial angles. The length of the corner modules is, in principle, unlimited; however, for static and practical (transportation) reasons, the length is 3,000 mm, preferably 2,400 mm. The corner modules can be cut to the required length by the DIY enthusiast using standard tools.

[0013] The modular system preferably comprises a further module from a fourth group, namely at least one end module. The end module preferably has a rectangular base shape with a width and a height, the width being adapted to the width of the prefabricated panel, analogous to the corner module. This base shape is hereinafter referred to as the cover element of the end module. According to a first embodiment, the end module is preferably formed in one piece with a "half" tongue, thus having a T-shaped structure in cross-section consisting of the cover element and the half tongue. The half tongue of the end element serves to engage in the groove of a panel that forms an end panel of a wall, or in the groove of several panels, forming the corresponding end panels. End panels are defined as panels that form the top row of several vertically stacked rows of panels in a wall.The half-tongue of the end module engages in the groove of the end panel(s) to stabilize them, and the cover element of the end module overlaps the outer surfaces of the panel adjacent to the groove to form a top edge. Alternatively, according to a second embodiment, the end module, or more precisely, its cover element, can have a groove (instead of a half-tongue), so that the end module, as previously described in connection with the corner module or the prefabricated panels, interacts with the tongue module of an end panel by covering the tongue module projecting from the panel. The length of the end modules is, in principle, unlimited; however, for static and practical (transport) considerations, the length is 3,000 mm, preferably 2,500 mm. The end modules can be cut to the required length by the DIY enthusiast using standard tools.

[0014] Preferably, the panel has a length of between 600 and 1,800 mm, particularly between 800 and 1,600 mm, preferably 1,200 mm. Advantageously, the height of the panel is between 300 mm and 600 mm, preferably 600 mm, and the width is between 20 mm and 160 mm, particularly between 40 mm and 120 mm, preferably 80 mm. A length-to-height ratio of 2:1 is particularly preferred, especially a panel with external dimensions of 1,200 mm x 600 mm.

[0015] It is particularly advantageous if the first group includes both panels with a length-to-height ratio of 2:1 and panels with a length-to-height ratio of 1:1. This allows for the advantageous construction of larger walls in a staggered pattern, avoiding cross joints and without cutting the panels on site.

[0016] These lengths and widths of the panels offer the advantage that they can easily be gripped and carried with both arms.

[0017] The surface weight depends on the materials used in the panel for the frame module, infill module, and covers, as well as the panel width. Preferably, the surface weight should not exceed 20 kg / m². 2 , which results in a weight of approximately 15 kg for the particularly preferred larger panels at a scale of 2:1, allowing for easy processing.

[0018] The second group's spring module (at least one of which is a support and connecting module) serves as a form-fitting component, which can be inserted into the groove of the frame module. Depending on its length, the spring module can either fill the entire groove length of one side of the frame module (in which case the groove length corresponds to the length of the frame module), or alternatively, only a portion of it. In this case, several spring modules are required to completely fill, for example, a longitudinal groove. Advantageously, the spring module has a standard length that corresponds to the length of the frame module. This makes production cost-effective. At the same time, DIY enthusiasts can easily cut the spring module to the required length. In a fully assembled soundproof wall (consisting of two panels), the first and second panels are connected to each other using the tongue-and-groove joint, ensuring that the front and back surfaces of the panels are flush and level with each other, without any gaps.

[0019] In an advantageous embodiment of the invention, the frame module is formed from four individual frame elements. Preferably, two frame elements represent longitudinal sides of the frame module and two frame elements represent end faces of the frame module.

[0020] The groove formed in the panel or frame module advantageously has a width of between 20 and 50 mm, particularly preferably 29 mm or 30 mm, and a depth of between 10 and 30 mm, particularly preferably 20 mm. The spring module, in turn, advantageously has a total length of between 600 and 2,480 mm, particularly between 800 and 1,680 mm, preferably 1,200 mm or 1,280 mm, a total height of between 20 and 60 mm, preferably 40 mm, and a total width of between 10 and 50 mm, preferably 30 mm.

[0021] Preferably, grooved frame modules are used in the prefabrication of the panels; alternatively, it is also possible to introduce the grooves in a final step in the panel prefabrication, preferably by milling the panel.

[0022] The dimensions of the groove and the spring module are matched to allow for easy insertion of the spring module into the groove. The spring module fits snugly and securely in the groove. Preferably, the formula: H FE (Height of spring module) = 2 × T N(Groove depth). To facilitate wall mounting, the height of the spring module can be reduced by a small amount of 3 to 5 mm relative to twice the groove depth. Advantageously, the overall length of the frame module corresponds to the length of the spring module. Naturally, the spring module must be shortened if it is to be inserted flush and completely around the groove on all four sides of the frame module. In this case, either the two end spring modules or the two side spring modules must be shortened accordingly so that the corners of the abutting spring modules are flush with the frame module.

[0023] A dimension of the frame module that defines the shortest distance between an inside and an opposite outside of the frame module is designated as length L1. This length is expediently between 20 mm and 80 mm, preferably 40 mm.

[0024] In a further preferred embodiment of the modular system according to the invention, the material of the frame module and / or the spring module is selected from: a rigid polyurethane foam, a rigid polyisocyanurate foam, a high-density functional material based on rigid polyurethane foam (known under the trade or brand name “Purenit®”), a wood-plastic composite (WPC) or an extruded polystyrene (XPS).

[0025] PURENIT® (trade and brand name) is particularly preferred as the material for the frame module and / or the spring module. PURENIT® is a high-density functional material based on rigid polyurethane foam from Puren GmbH, Rengoldshauser Strasse 4, 88662 Überlingen, Germany. PURENIT® consists primarily of recycled polyurethane waste processed into a highly compressed panel. Like wood, PURENIT® can be milled, sawn, drilled, and screwed using conventional woodworking machinery.

[0026] The filling modules can have a bulk density of between 10 and 220 kg / m³. 3 , especially between 20 and 150 kg / m² 3 , preferably between 30 and 80 kg / m² 3The dimensions (length, height, width) of the infill modules are always expediently chosen so that the infill module or modules, which are placed side by side and abutting each other lengthwise in the interior of the frame module, form a rectangle (optionally a square) exactly matching the dimensions (length, height, and width) of the interior. The total width of the infill modules is equal to the total width of the frame module, which is self-explanatory. Otherwise, the cover modules could not be flush with the front and back surfaces of the frame and infill modules.

[0027] According to a further advantageous embodiment of the modular system, the material of the filling module is selected from mineral wool, in particular glass or rock wool, a fibrous insulation material such as wood fiber, cellulose, hemp, flax, sheep's wool, or coconut fiber. Specifically, the mineral wool can be rock wool produced using a manufacturing process for glass wool and marketed under the name "Ultimate®" by Saint-Gobain ISOVER G + H AG, Bürgermeister-Grünzweig-Str. 1, 67059 Ludwigshafen, Germany.

[0028] Advantageously, the first cover module completely covers the front of the frame module as well as the front of the at least one infill module or infill modules when fully assembled, so that only the first cover module is visible on the front of the panel. This also applies to the second cover module, which advantageously completely covers the back of the panel.

[0029] The cover modules protect the internal modules from dirt, water, and other external influences. Furthermore, this modular panel design with integrated cover modules is advantageous because it eliminates the need for separate structures, such as a housing, stand, plate, or similar, around the heat pump, generator, compressor, etc., which would otherwise provide additional protection for the internal modules, supplementing noise reduction.

[0030] For practical reasons, both the first and second cover modules of the panel are designed as a single plate.

[0031] The plate of the first cover module and the plate of the second cover module are advantageously each independently formed from the following plates or materials: • fleece-reinforced gypsum boards according to DIN EN 15283-1, preferably type GM-FH1 • High-pressure laminate sheets according to EN 438-6:2016 • Metal plates, preferably stainless steel, aluminum or Corten steel, • Wood • High-pressure laminate (HPL), • Nonwoven materials, especially those based on glass fibers, polypropylene fibers, polyethylene fibers, polyethylene terephthalate fibers • Fibre fabrics, especially made from fibers such as cotton, polyester or fiberglass

[0032] For the aforementioned fleece-reinforced gypsum board, wood panels, or high-pressure laminate panels, the panel thickness is preferably between 10 and 20 mm. The aforementioned high-pressure laminate panel, on the other hand, has a preferred thickness of between 10 and 30 mm. In the case of a metal panel, a thickness of 0.5 to 2 mm is preferred. If the panel is made of one of the aforementioned fleece materials or fibrous fabrics, a preferred thickness is 80 µm to 2 mm. These thicknesses ensure very good panel stability and, with each of the selected materials, allow for easy handling.

[0033] Covers based on metal plates or sheets are particularly preferred due to their weather protection, mechanical strength and low material thickness.

[0034] In a particular embodiment of the modular system, the panel is closed, preferably as a smooth panel. However, it can also be perforated, preferably in the form of a hole pattern or a pattern with a multitude of square or rectangular openings. A regular pattern is particularly preferred, but it can also be irregular. The perforated panel allows some of the (secondary) sound from the sound-generating device to reach the underlying frame and infill module(s), which, as a porous absorber material, absorbs the sound instead of being completely reflected by the panel. Advantageously, the side of the panel with the perforated plate faces the sound-generating device after installation.

[0035] It is particularly advantageous if the first cover module is a smooth panel and the second cover module is a perforated panel. In the case of a metal cover, the smooth panel preferably has a thickness of 1.5 mm and the perforated panel a thickness of 1 mm, expediently with 5 / 6 perforations. Preferably, the smooth panel forms the first cover module and the perforated panel the second. Alternatively, the panels are identical on both sides, i.e., smooth or perforated. In the prefabricated panel, the perforated cover module is expediently perforated in the area of ​​the infill module. In the area of ​​the frame module, the perforated cover module is expediently not perforated, since this is where the cover module is ultimately attached to the frame module. The perforation of the perforated panel is ≥ 25% of the surface area, preferably ≥ 30%, and particularly preferably ≥ 32%.

[0036] The respective cover module is bonded to the frame module. Alternatively, mechanical fasteners such as screws are possible, but less preferred. Polyurethane adhesive or foam, or alternatively epoxy resin, are suitable adhesives. In special cases, a polymer resin-based contact adhesive can be used. This ensures a secure and permanent bond.

[0037] The invention also relates to a soundproof wall or soundproof capsule. This comprises at least a first and a second panel of the modular system and optionally at least one corner module and / or an end module, as described above. In this finished wall or capsule, a first spring module engages in a first groove formed on the longitudinal side of the frame module of the first panel and simultaneously in a second groove formed on the longitudinal side of the frame module of the second panel.

[0038] Preferably, during the manufacture of this wall or capsule, half the height of the first tongue module is inserted into the first groove, and the opposite half of the height of the first tongue module is inserted into the second groove, so that half the height of the tongue module is completely embedded in each groove. Naturally, the first tongue module is inserted all the way to the bottom of the groove and fits snugly into the finished wall or capsule. The long side of the first panel and the long side of the second panel are thus butted together via the described tongue-and-groove joint. It is essential that the tongue module is inserted into the respective groove on the long sides in its longitudinal orientation to allow the tongue module to be completely inserted into the two opposing groove sections.

[0039] The soundproofing panels according to the invention, which are configured with the at least one spring module according to the modular system according to the invention, can be used to produce a soundproof room, a soundproof wall or a soundproof capsule.

[0040] When a soundproof wall or soundproof enclosure is formed from several prefabricated panels, panels are located on the outside or at the edges of the wall / enclosure, forming its termination. The T-shaped termination module can be inserted into the outer groove of these end-closing panels on one of the long sides and / or one of the end faces, with its tongue engaging. Alternatively or additionally, the U-shaped termination module can be fitted over an outwardly projecting half of a tongue module (5) of an end-closing panel. To form an enclosure or even one of several rooms, the corner modules with two or three grooves can be used.They connect two or three prefabricated panels together at a corner and / or lengthwise by connecting the prefabricated panels via tongue modules to some or all of the grooves of the corner module. It is even possible to design the corner module with four grooves to form a kind of inner column of a capsule with four rooms.

[0041] The prefabrication of the panels with the described modular structure provides the processor or DIY enthusiast with standardized elements with which a variety of secondary sound insulations can be implemented in a predetermined grid dimension.

[0042] Two preferred embodiments of the invention are described below with reference to the purely schematic drawings. These show Fig.1 a perspective view of a first prefabricated panel 1 according to a first embodiment comprising modules of a first group, namely a frame module 2, a (non-visible) infill module 6 as well as two cover modules 12, 13, and a spring module 5 of a second group of modules; Fig. 2 an enlarged view of a corner area of ​​the first panel 1, as in Fig. 1 shown and circled, but only the frame module 2 of panel 1 is shown, Fig. 3 a cross-section along line CC, as in Fig. 1 characterized by the first panel 1 in the prefabricated state, here with two spring modules 5 inserted into correspondingly horizontal groove sections of the groove 3 of the frame module 2, wherein an upper end and a lower end of the modular panel 1 are shown in partial view, Fig.4 A front view of a soundproof wall made of seven prefabricated panels 1, 1', two corner modules 15 (left and right in the picture), which are in Fig. 5 as such are shown, and two final modules 16, 16' (here purely as examples, designed differently), each in Fig. 6 and Fig. 7 are shown as such, Fig. 5 a first cross-section of a corner module 15, Fig. 6 a cross-section of a final module 16, Fig. 7 a cross-section along line CC, as in Fig. 1 characterized, however by a prefabricated panel 1' with modified module dimensions and an additional end module 16' according to an alternative embodiment.

[0043] Fig.Figure 1 shows a perspective view of a first modular panel 1 according to a first embodiment of the invention, which consists of a frame module 2, here of four individual elements, a first and a second cover module 12, 13 and a, in Fig. 1. A non-visible, filling module 6 is formed. A first spring module 5, which is a module of a second module group of the modular system according to the invention and is used to create a connection between two panels 1, 1', is also shown. For this purpose, the spring module 5 is inserted modularly into a longitudinal section, as shown here, and / or into an end section (not shown) of a groove 3 of the frame element in the first panel 1. The first panel 1 has an upper longitudinal side LS 1, a lower longitudinal side LS2 and two end faces S1 and S2, these reference symbols being used identically for the frame module 2.

[0044] The length of the first panel is 1 L Pcorresponds to the length of the frame module L R The height of the first panel is 1 H P corresponds to the height of the frame module H R The frame module 2 has a groove 3 on its outer surface, which is formed centrally on the outer surface 4 and circumferentially around the frame module 2. It forms one vertical groove section on each of the two end faces S1, S2 of the frame module 2 and one horizontal groove section on each of the two longitudinal sides LS. 1,LS2. A vertical arrow P1 indicates the insertion direction of the first spring module 5 shown, which is inserted from above into the groove 3 of the frame module 2 below, more precisely into the horizontal groove section of the longitudinal side LS1 of the upright panel 1. Further spring modules 5, preferably three, can be inserted; one from below into the horizontal groove section of the longitudinal side LS2 and one each into the vertical groove sections of the two end faces S1 and S2 (not shown here). Advantageously, the spring modules 5 have a length that allows the groove sections of the circumferential groove 3 to be completely filled with preferably four spring modules 5, such that the spring modules 5 abut each other, more precisely at an angle. Advantageously, the spring modules 5 that are inserted on the longitudinal sides LS1 and LS2 of the frame module 2 have the length of the longitudinal side L. Rof the frame module 2 and the spring modules 5, which are inserted at the end faces, the length of the height H R the end faces S1, S2 of the frame module 2 minus the height of a spring module H FE .

[0045] The spring modules 5 can, in particular, have a standard dimension, which allows for simpler and more cost-effective spring modules from the manufacturer's perspective. For example, a length L FE of 1,200 mm or 2,400 mm, a height H FE of 40 mm and a width B FE of 29 mm or 30 mm.

[0046] In the illustrated first embodiment of the first panel 1, the first cover module 12 is a smooth sheet metal with a thickness or width of 1.5 mm. The first cover module 12 is placed on the front surface 10 of the frame module 2 and bonded to it. The infill module 6, located inside the frame module 2, is concealed behind the first cover module 12 and is not visible. The infill module 6 can be bonded to the first cover module 12 at its front surface 8, just like the frame module 2. However, this is not strictly necessary, as the infill module 6 is wedged or embedded between the first and second cover modules 12, 13.

[0047] The second cover module 13 of the in Fig.The first panel 1 shown in Figure 1 is advantageously a perforated sheet with a thickness of 1.0 mm, wherein the sheet is designed with a 5 / 6 perforation pattern with a perforation area of ​​at least 32% as a controlling element for sound absorption. The 5 / 6 perforation pattern can be characterized by the following Table 1, valid for the first embodiment shown and further embodiments (not shown here): Table 1: Dimensions of a second cover module 13 according to an advantageous embodiment Dimension type Value plate 1.200 × 600; 600 × 600 thickness 1.0 mm Hole diameter 5mm, or alternatively 8mm Axle spacing of hole pattern 15mm, alternatively 18mm, 23mm or 25mm (depending on type) Perforation area ≥ 32% Hole pattern 5 / 6 per row, alternating and staggered

[0048] As is clear from the in Fig. 2 shown enlarged view of a corner area of ​​frame module 2 of the in Fig. As can be seen from the first panel 1 shown in Figure 1, the frame module 2 is provided with a circumferential groove 3, which projects inwards towards the inside of the frame module 2 from the center of the outer surface 4. The depth of the groove T NIn this exemplary embodiment, the depth is 21 mm, which is purely illustrative. Typically, the groove depth T will be... N The length L1 is measured to half the distance between the outer surface 4 and the inner surface 14 of the frame module 2, with deviations of up to + / - 5 mm. In the frame module 2 shown, the length L1 is 40 mm. The width of the frame module B R In the illustrated embodiment, this is 80 mm and thus represents the sum of the groove width B. N (here: 30 mm) and the remaining two end widths L2 and L3 (here: 25 mm each) of the outer surface of frame module 2. These widths can vary depending on the application for sound insulation. As a rule, the dimensions mentioned may deviate by up to +20 mm or -10 mm. The interior space 7 is visible on the inside of frame module 2; for simplicity, the infill module 6 has been omitted. Fig.Figure 2 shows only the frame module 2 as a module of the first modular panel 1, i.e., an unfinished state of the first panel 1. The two in Fig. The first and second cover modules 12, 13 shown, the filling module 6 and the first spring module 5 are in Fig. 2 not shown.

[0049] Fig. Figure 3 shows a cross-section through the prefabricated first panel 1, here with two spring modules 5 inserted into the horizontal groove sections of the groove 3 of the frame module 2, showing an upper end and a lower end of the modular panel 1. If a first spring module 5, as in Fig. 3 shown, at least half of its height H FEOnce the first panel 1 is inserted into the horizontal groove section on the upper longitudinal side LS1 of the frame module 2 in the first panel 1, a second panel 2 can be placed on top of the first panel 1 and connected to the first panel 1 via a positive-locking tongue-and-groove connection using the spring module 5. A clamping fit ensures a secure hold of the first spring module 5 in the respective groove 3 of the first and second panels 1, 1'.
