Description

Description

The invention relates to a sound-insulating interior or exterior wall cladding using insulating panels.

For sound insulation in interior rooms, it is known to cover interior walls with wood paneling.

_/ .-> cladding or attaching specially shaped ceramic panels to the interior walls. The -j ceramic panels have a structured surface to create a sound-absorbing effect. They are attached to the interior wall with adhesive or mortar and grouted. Attaching the panels is therefore very labor-intensive and costly. The achievable sound insulation effect, however, is often unsatisfactory.

Various types of soundproof walls are known for soundproofing in outdoor areas, e.g. on roads and highways. Large panels made of wood, glass, metal or concrete are attached to large posts. In order to achieve sufficient soundproofing, the panels must be sufficiently thick, which means that a considerable amount of work and material is required.

The invention is based on the object of specifying a sound-insulating wall covering for interior and exterior use, which can be completed inexpensively and with considerably less work and with which a high sound insulation effect is achieved.

According to the invention, the object is achieved in that the insulation panels are provided with hollow chambers running in the direction of their length or width and/or grooves and/or slots arranged on their facade side and/or holes made from their facade side or perforations running across the insulation panels and have at least one fastening groove or fastening undercut on their lower side at least in the area of the corners and at least one fastening groove, fastening undercut or rear fastening web on their upper side at least in the area of the corners and are suspended in holding elements of vertical holding rods connected to a substructure or a building wall at a distance of the grid length of the insulation panels or forming the basic structure.

P98537DE

The panels can be made of aerated concrete, clinker, sand-lime brick, clay, porous ceramics or other ceramic and thus maintenance-free and environmentally friendly, recyclable material. Their surface can be roughened or smooth or glazed. To increase the sound insulation effect, they can be provided with slots, grooves or holes in various patterns, so that visually interesting and different facade structures as well as acoustically different sound insulation values can be achieved.

The solution is suitable for indoor use in schools, sports halls, swimming pools, concert halls, multi-purpose halls, theaters, cinemas, workshops, train stations, airports and other transport facilities, retail outlets, churches and other cultural facilities, whereby it can involve the soundproofing renovation of existing buildings as well as new ones. Outdoors, soundproofing walls can be built in this way in the vicinity of roads and highways. The solution can also be offered for the construction of self-construction soundproofing fences.

The wall cladding is non-flammable, which is a great advantage, especially indoors. It is also waterproof and dirt-repellent and easy to clean, which is important for use in swimming pools or industrial buildings. Overall, the result is a ventilated facade with a heat-regulating effect.

Attaching the substrate and the panels is easy and does not require any special knowledge. The solution is therefore particularly suitable for subsequent installation, even as a DIY measure.

The costs are considerably lower than the state-of-the-art solutions described.

The insulation panels can be designed in such a way that at least some of the slots, grooves or holes reach up to the hollow chambers.

The hollow chambers and/or grooves and/or slots and/or holes in the insulation panels can be at least partially filled with an insulating material. Instead of filling the hollow chambers etc., an insulating panel can also be applied as a whole to the back of an insulation panel, which is particularly suitable for insulation panels with transverse openings.

P98537DE

High-quality sound insulation is achieved when the insulation panels consist of a base plate and a cover plate, which are provided with corresponding undercuts on their inner sides, where they are elastically connected to one another by means of inserted, correspondingly shaped rubber strips.

The support rods are preferably made of bent sheet steel, with the support elements for the insulation panels in the form of support bars formed by punching and bending. They can also be assembled from several individual rods, e.g. spot-welded, or made from extruded aluminum profiles. They are preferably provided with hook-shaped cutouts for hanging them up or with fastening holes.

An even more flexible system is achieved if the holding elements are not molded onto the holding rods, but the holding rods are provided with openings or shaped noses into which appropriately shaped holding elements, i.e. panel holders, can be inserted or plugged on. Similar openings can also be advantageously provided for mounting other facade elements. The holding elements and brackets can in turn be made of sheet metal or an extruded aluminum profile, or even wire. For acoustic decoupling of the wall cladding and for elastic mounting of the facade panels on the holding elements, elastic supports on the latter are recommended.

The retaining rods can be designed in such a way that a slot remains at the front into which joint panels made of rubber or plastic can be pressed, which are held there in a force-fitting and/or form-fitting manner.

In addition, it is advantageous to have bars bent or formed onto the support rods, onto which strip-shaped springs made of rubber or plastic are attached, which then exert a force on the insulation panels from behind, holding them elastically and dampening acoustic vibrations.

A particularly simple and technologically advantageous way of attaching the support rods is to suspend them from vertical hollow profile rods or sections of these, which

P98537DE

· I

preferably have an upward-facing fastening bar. These hollow profile bars can also be bent from sheet metal.

The support rods can also be attached to a building wall or an underground framework and acoustically decoupled from it by connecting the support rods to elastic strips, which in turn are connected to fastening devices for the underground framework or the building wall. These elastic strips are preferably made of rubber with a textile insert.

For outdoor installation as a one- or two-sided noise barrier, the support rods can be attached to posts or the posts already have a corresponding profile that corresponds to the shape of the support rods.

The figures, even if they show horizontal representations or sections, are arranged in portrait format for easier handling.

Fig. 1 shows the invention in a first overview. Insulation panels 2 are suspended at the corners of vertical support rods 1, which are attached to a substructure (not shown here). The support rods 1 are provided with bent support webs 3 for this purpose. The insulation panels 2 each have a groove 4, 5 at the top and bottom, into which the support webs 3 engage.

For acoustic decoupling, elastic supports 6 can be placed on the support webs 3 before hanging the insulation panels 2, which guarantee a firm but elastic fit of the insulation panels 2.

To cover the remaining vertical joints between the insulation panels 2, joint panels 7 made of rubber or plastic are provided, which are pressed into a gap in the support rods 1 and which simultaneously secure the insulation panels 2 in the lateral direction.
25

The insulation panels 2 are provided with hollow chambers 8 running in the longitudinal direction, which in this case end in continuous grooves 9 at the front. In order to increase the sound insulation, insulation strips 10 are inserted into the hollow chambers 8.

Fig. 2 and the sectional views according to Figs. 3 and 4 show an insulation panel 2 which has individual round or square holes 11 instead of the continuous grooves at the front.

Such insulation panels 2 can be made of ceramic, whereby the shape including the hollow chambers 8 and the grooves 9 as well as the grooves 4 and 5 are formed by extrusion in a

P98537DE

The plates are cut perpendicular to the pressing direction. The holes 11, however, must be additionally made after extrusion.

Fig. 5 and 6 show a further variant of an insulation panel 2 with offset round holes 11 or rectangular slots 12.

A variant with rounded slots 12 or continuous grooves 9 is shown in Fig. 7. The latter variant corresponds to the overall view of the wall covering already shown in Fig. 1. The same sectional views are obtained as shown in Figs. 3 and 4.

Fig. 8 shows a variant with continuous horizontal grooves 9 (upper part of the image) and additional vertical grooves 13. As can be seen from the corresponding sectional view in Fig. 9 , here the grooves 9 are not connected to the longitudinal hollow chambers 8. The grooves 13 have a smaller depth than the grooves 9.

Fig. 10 is an overall view of a wall covering according to the invention with partially suspended insulation panels 2, as previously described. The view shows that the support rods 1, which carry the insulation panels 2, are only attached to a few attachment points on a sub-base lath framework 14. The preparatory work is thus limited to attaching a few attachment parts into which, as will be shown later, the support rods 1 are hung, onto which the insulation panels 2 are then simply hung.

In Fig. 11 and the associated sectional views Fig. 12 and 13, a variant of an insulating panel 2 is shown in which round or square holes 11 are realized together with grooves 9.

Fig. 14 is a representation of another variant of an insulation board 2 with continuous grooves 9 analogous to Fig. 7 and possibly with additional slots 12.
30

The cross-sectional images again show the same picture as shown in Fig. 12 and 13.

P98537DE

Fig. 15 now shows an insulation panel 2 analogous to Fig. 11, which has additional longitudinal grooves 15 between the grooves 9, so that a very fine structure is created, which ensures even higher sound insulation.

Fig. 16 and 17 again show corresponding sectional views.

The insulation panel 2 according to Fig. 18 is also provided with additional longitudinal grooves 15, which otherwise corresponds to the insulation panel 2 shown in Fig. 14.

Further variants of the surface design of the insulation panels 2 are shown in Fig. 19-23, whereby instead of the longitudinal grooves 15, elevations 16 can also be provided. The remaining design can be carried out analogously to the previously discussed embodiments, i.e. with individual holes 11, slots 12, grooves 9 or combinations of these.

Finally, Fig. 24-26 show an insulation panel 2 with particularly deep longitudinal grooves 15 into which additional groove insulation strips 17 made of rubber or plastic can be inserted for particularly high sound insulation.

Such insulation panels 2 can, like those previously shown, also be manufactured in two fastening variants, as shown in Fig. 27, so that they can be suspended alternately with horizontal and vertical longitudinal grooves 15.

An insulation panel 2 with a particularly high acoustic insulation effect and mechanical strength is shown in Fig. 28 and 29. The insulation panel 2 is designed as a double panel and is therefore thicker than those shown so far. It has hollow chambers 8 in two layers. These can be connected on the front with continuous grooves 9, slots 2 or holes U (not shown here). Insulation strips 10 can in turn be inserted into the front hollow chambers 8, as shown in the section in Fig. 31. These insulation panels 2 are particularly suitable for higher mechanical stresses, e.g. for gyms.

The insulation panels 2 can also be manufactured with through holes 11, as can be seen from Fig. 30 and 31. The insulation panels 2 are then extruded in the direction of these holes 11 and cut so that the cut surfaces form the front and back of the insulation panels 2. This variant has the advantage that an insulation mat 20 can be placed in the

P98537DE

The size of the insulation panels 2 can be easily applied to them from behind. For this purpose, fastening pins 21 made of plastic are provided, which are pushed through the insulation mat 20 and hold in the holes like barbs.

The examples of soundproofing panels shown so far relate in particular to arrangements in interior areas. A special design for external walls is shown in Fig. 32-34. Since the panels for outdoor use have to cover each other like shingles because they are also exposed to rain, the insulation panels 2 are provided with only a web 18 on their upper side instead of a groove. On the lower side, the rear border of the insulation panels 2 is set back from the front so that a web 19 is formed on the latter.

Fig. 35 shows the hanging of such panels 2 for an external wall cladding as a section of an overall view of the wall cladding.

All of the insulation panels 2 described so far can be separated by cutting along a dividing line that runs parallel to a hollow chamber 8 so that the same profile is produced on the top or bottom as with an undivided insulation panel 2, so that individual dimensions can also be produced for filling remaining gaps.

An insulation panel with a particularly high insulation effect is the subject of Fig. 36-38. The insulation panel is in two parts and consists of a base plate 22 and a cover plate 23. Base plate 22 and cover plate 23 are held together by two rubber strips 24. In order to achieve specific elastic properties of the rubber strips 24, these are provided with longitudinal round or slot-shaped openings 25 on the inside and are profiled in such a way that they engage behind undercuts 26 in both panels. In relation to the entire facade, such double panels result in a rubber-mounted upper facade.

Fig. 38 clearly shows the assembly of such an insulation board.
30

The following drawings describe the suspension of the insulation board 2 on a substructure. Fig. 39 shows a sectional view of a first variant. Horizontally running hollow profile bars 28 are attached to a building wall 27. The hollow profile bars 28 can extend across the entire wall surface, but

P98537DE

even short sections can be screwed to the building wall 27 in a grid pattern. The hollow profile bars 28 can be made from folded sheet steel. They have an upwardly protruding fastening web 29 into which the support bars 1 with their cutouts 30 are simply hooked. The support bars 1 are also made from folded sheet steel and are provided with holes 31. A locking plate 32 can be placed under the hollow profile 28 and can be attached to the holes 32. The support bars 1 can then no longer be lifted out.

The fastening to the hollow profile bars 28 has the advantage that there is enough space behind the support bars 1 for installation lines, pipes, insulation material, etc., as indicated in the drawing. The support bars 1 have supporting webs 3 pointing to the side, which then hold the insulation panels 2, here with acoustically decoupling elastic supports 6 in between.

Fig. 40 shows a section through this substructure as a top view. This type of fastening corresponds to the example that was already used in the illustration for Fig. 1. As was already shown there, the remaining vertical joint between the insulation panels 2 is filled by a joint panel 7, which is simply pressed into the front gap of the support rods 1.

Fig. 41-44 show the support rod 1 in individual representation in two views and two sections. Additional bends 33 are provided for secure attachment to the hollow profile rods 28.

The elastic support 6 in individual representation in three views is shown in Fig. 45-47.

The shape shown in Fig. 48 is particularly suitable for outdoor use, as will be shown later.

Fig. 49 shows the interaction with the supporting webs 3 of the holding rods 1.

The suspension of the insulation board 2 according to Fig. 50 is a variant of the suspension just discussed, especially for outdoor areas. The hollow profile bars 28 are used here for

P98537DE

to support brackets 34 for better force absorption. This also makes it possible to adjust if the wall surfaces are not very flat.

Instead of being made from bent sheet steel, the support rods 1 can also be made from extruded aluminum profile. Such an embodiment of the support rods 1 described so far is shown in Figs. 51-53.

Another, very space-saving version of support rods 1 is shown in perspective in Fig. 54. Fig. 55 shows the arrangement in a sectioned side view, but here with insulation panels 2 designed as a double plate, and Fig. 56 shows this arrangement in a sectioned top view. The support rods 1 consist of two folded partial sheets which, as Fig. 56 shows, are joined together by means of spot welding. The support rods 1 are intended to be attached directly to a building wall 27. In order to additionally support the insulation panels 2 from behind, strip springs 36 made of rubber or plastic are placed on the bends 35 of the support rods 1.

The following drawings show a support rod 1 made of sheet steel, the 180° bend of which is not on the wall side but on the facade side. One of the advantages of this variant is that no joint panels are required.

Fig. 60 shows a variant in which the support rod 1 is not placed directly on a hollow profile rod 28, but with an intermediate support bracket 37 and an elastic support 38. The support rods 1 are thus acoustically decoupled from the building wall 27. In addition, a large distance is created from the building wall 27, which is required, for example, if large-format pipes are laid on it. Fig. 61 shows the arrangement from above. Figs. 62-65 show the support rod 1 in individual representation.

Analogous to Fig. 54, the support rod 1 can again be provided for direct, space-saving fastening to the building wall 27, as can be seen from Fig. 66. Here, too, corresponding strip springs 36 are used, which have a slightly different profile than the version according to Fig. 54. The support rods 1 in side and front views are shown in Figs. 67 and 68.

Fig. 69 and 70 show a possibility for holding facade elements on a support rod 1. In slots 41 located at the front of the support rod 1, holding elements can be

P98537DE

42, to which facade parts, such as a downpipe bracket, can then be attached. This option is particularly important for outdoor areas.

As shown in Fig. 71 and 72, the support rods 1 can also be attached to the building wall 27 using angle irons 39. As can already be seen from the illustration in Fig. 72 and becomes even clearer from Fig. 73-78, with this type of support rod 1, no support webs are formed on the support rod 1. Instead, separate panel holders 40 are pushed through slots 41 in the support rod 1 and anchored by sliding downwards. The solution is much more flexible than those previously discussed, since the support rods 1 are thus suitable for different panel sizes or for individually divided insulation panels 2. Fig. 75 shows a panel holder 40 for holding an insulation panel 2 on each side of the support rod 1, Fig. 78 shows a one-sided panel lifter 40.

A corresponding support rod 1 for direct wall mounting is shown in Fig. 79, here with an acoustically decoupling elastic base 43 between support rod 1 and building wall

This type of support rod 1 can also be made of aluminum extruded profile 1, as shown in Fig. 80-82. Instead of the front slots, the support rod 1 then has corresponding shaped noses onto which the plate holder 40 can be placed. A plate holder 40 for this type of support rod 1 is shown in Fig. 83 and 84.

Another possibility for acoustic coupling to the building wall 27 can be seen in Fig. 85. The fastening is made to angle irons 44, which are connected to the support rod 1 via elastic bands 45 made of rubber with textile insert.

Another type of acoustic decoupling, here between the insulation panels 2 and the support rod 1, is shown in Fig. 87-92. The support rods 1 are provided with holes 46 in the area facing the facade. Wire brackets 47, e.g. made of stainless steel wire, can be inserted through these holes 46, onto which buffers 48 are in turn inserted, which are somewhat elastic and which then hold the insulation panels 2. The solution again leads to a universal, flexible system, since the holes 46 can be inserted at short intervals.

P98537DE

Fig. 93 and 94 show the wire bracket again in an enlarged view, from which the surface profile can also be seen, which ensures that the buffers 48 are firmly seated.

The following drawings finally show a final basic form of a support rod 1.
5

Fig. 95 is initially a perspective view of the entire structure. The support rod 1 is again made of bent sheet steel. The insulation panels 2 are suspended using special panel holders 49 which are hooked into openings 50 in the support rods 1 from the front. Elastic supports 6 made of rubber or plastic are again provided for acoustic decoupling and elastic support of the insulation panels 2. The vertical joint between the insulation battens 2 is covered with a joint cover 51 which, with its bulges 52, also acts as a spring engaging the rear of the insulation panels 2.

Fig. 96 shows a side section and Fig. 97 a front view of this arrangement. Fig. 98 is a sectional plan view.

The space-saving fastening to the building wall 27 is shown in Fig. 99, from which it can be seen that a corresponding elastic base 53 is provided at the fastening points.
20

In Fig. 100-102 the plate holders 49 are shown as an extruded part. The corresponding profile shape for the elastic supports 6 is shown in Fig. 103-105.

The plate holders 49 can also be manufactured as sheet metal parts, as shown in two variants in Fig. 106-111, or as parts bent from wire, for example stainless steel wire, as can be seen in Fig. 112-114.

Another form of panel holder 49 for external walls is shown in Fig. 115-117.

A modified form of the facade panel 51 compared to Fig. 95-99 is shown in Fig. 118-120. This is particularly suitable for thicker insulation panels 2 for use in the external wall area, which are then also supported against each other in the front area.

The last described support rod 1 can be seen again as an individual illustration in Figs. 121 and 122.

If this is not to be made from sheet metal, but as an extruded profile 1, the result is, for example, a shape as shown in Fig. 123-125.

Fig. 126-128 show once again the hollow profile bars 28 made of bent sheet steel, which in this case are also provided with notches 54 which accommodate the holding bars 1 between them in a form-fitting manner.

One possibility for the construction of free-standing soundproof walls is shown in the illustrations in Fig. 129 and 130. The insulation panels 2 are suspended on posts at a distance equal to the grid length of the insulation panels 2. In the case of the exemplary embodiment according to Fig. 129, a special support post 55 is provided, which can be made of aluminum and which already takes over the function of the support rods 1 described so far, in that one side has a profile of a support rod. It goes without saying that two sides can also be profiled accordingly, so that insulation panels 2 can be attached to both sides of the support post 55.

According to Fig. 131, a normal rectangular profile pile has been used, which can be made of steel and to which suitable support piles 1 are screwed, here on both sides.

All sheet metal parts described can be galvanized or plastic-coated or otherwise protected against corrosion.
