Description

The present invention relates to a device for Butt joint insulation, in particular damping of vibration transmission, between abutting components, such as wall elements, walls, Floors, ceilings, in particular a load-bearing component and a non-structural component.

Thanks to a space-saving and cost-saving construction method, the thickness of the building materials in the wall and ceiling area has been steadily reduced. As a result, the mass of the load-bearing walls required for sound insulation is no longer sufficient to compensate for the sound energy transmitted by integrated non-load-bearing inner partition walls. The average basis weight of 300 kg / m ² required for sound insulation according to the DIN 4109 standard is no longer achieved with integrated non-load-bearing inner walls. Therefore, increased sound insulation cannot be achieved by applying correction factors.

An impact from non-load-bearing inner walls to the load-bearing walls installed insulation materials prevent mutual Vibration excitation of load-bearing walls and non-load-bearing partitions, but are due to the construction due to system-related plaster bridges between the non-loadbearing inner walls and the loadbearing walls proven to be essentially ineffective. This also applies to cork strips with a thickness above 7 mm in particular to compensate for any Bumps on the walls and floors and a width equal to that Stone width is. It has emerged that emerging Plaster bridges lead to the transmission of sound waves at the end of the wall. This The technical situation applies analogously to ceiling and floor connections.  

Non-load-bearing internal partitions are currently being used on construction sites Toothed by flat steel anchor connections or by plaster bracket with connected to the load-bearing walls. The achievable joint insulation dimension is less than 15 dB with these systems. It has emphasized that for acoustic decoupling at least 25 dB should be achieved. This is with the measures taken Butt joint insulation according to the prior art is not possible.

The invention is therefore based on the object of a device for Butt joint insulation, in particular damping of vibration transmission, between abutting components, such as wall elements, walls, Floors, ceilings, in particular a load-bearing component and a non-load-bearing component, to the extent that a acoustic decoupling of the components is achieved.

The task is performed by a device according to the preamble of Claim 1 solved in that the device is a profile that a Base part for attachment to a first component and at least one Has receiving part for receiving a part of a second component. Further developments of the invention are in the dependent claims Are defined.

This creates a device for joint insulation, which enables acoustic decoupling. By inserting one such a device or such a profile between components, such as Wall elements or walls and / or between wall elements or walls and ceilings and / or floors of a building becomes a direct material Connection between these parts, in particular load-bearing and non-structural components, essentially avoided. advantageously, is each between the non-load-bearing and the load-bearing components Touch by rigid, especially mineral building materials, such as plaster, Screed or the like avoided. A sound transmission can thereby  no more or at least hardly any or very subdued. As disturbing noise transmission from a room in a building another can thereby be reduced to an acceptable level. The device is advantageous in terms of its geometry and / or Choice of materials designed so that vibration transmission over them can essentially be prevented, in particular a transmission the bending and longitudinal vibrations generated by sound waves, since these absorbed by the device and essentially not be passed on.

With the device it is advantageously possible to vibrate the one, ie lighter or heavier wall element or the lighter or heavier wall in the longitudinal and transverse wall directions with a change in length of the wall element or the wall of z. B. 5.10 ^-6 m in both directions. The joint insulation dimension is clearly above 25 dB when using the device or the profile. Non-loadbearing walls or wall elements are therefore considered to be acoustically decoupled and the requirements for increased sound insulation can be more easily met in the overall system of the building.

The particular advantage of the device over the measures for State of the art soundproofing also consists in the fact that the Installation of the device for joint insulation in the Essentially no additional tools or materials like glue or similar in the area of the included wall element or the included Wall required. The profile can be in a certain area with a used mortar or plaster to plaster the non-load-bearing wall or the non-load-bearing wall element and / or stones or elements are used in the profile, especially with the in the stability required by the DIN 4103 standard. A major advantage of Device also consists of a processing error Sound transmission occurring in the form of plaster bridges essentially  can be excluded. The device also serves as a fixing and Installation aid for non-load-bearing walls or wall elements, facilitated the work of the craftsman and thus increases the quality of the work on Construction.

The profile is preferably essentially U-shaped. This creates a base part in the lower u-range and a receiving part in its encompassing area. The u shape can be easily matched to the shape and Thickness of the wall element or wall to be encompassed to adjust. It is also easy to manufacture and offers Possibility of a springy and problem-free attachment to the wall or the wall element. The receiving part preferably has at least one Legs for gripping, in particular springy gripping on the second Component, in particular wall or wall element. Particularly preferred the at least one leg is resiliently attached to the base part and / or the at least one leg is inclined so that a fixed one Hold on the inserted component is made possible. The component, in particular wall or wall element is thereby in the profile or Device clamped so that no further adhesive or the same device for connecting is more required. A firm one material connection between the or the legs of the device or the profile and the component is advantageously avoided to the Prevent transmission of vibrations through this.

So that the profiles can be easily placed on elements of the inner walls can and do not slip or stones of the walls in the edge area are already held well by the profile when they are inserted Legs when placed on the wall element or the stone or brick Profile advantageous under tension on it. Preferably have legs and / or tab element on the legs an inclination to the inside the device and thus to the component to be inserted, such as. B. wall or wall element. To achieve particularly good clamping,  corresponds to the clear width between two legs of the device in the Essentially the thickness of the insertable or between the legs inserted component. In particular, the clear width is so much smaller than the strength of the component that a clamping attachment to this arises.

Alternatively or in addition to the inclination of the leg or legs preferably the leg or legs with one or more tab elements for mounting on the second component, in particular a non-load-bearing one Wall or a non-load-bearing wall element. The Tab elements are preferably resilient or on the Thighs provided and grip only in a narrow, in particular linear area on the inserted or second component to be inserted. This allows the component to be supportive are held by taking up vibrations through the profile or the device.

This can not only the hold on the particularly load-bearing component can be improved. It there is also contact between the second, especially non-load-bearing Avoided component and the base part, which would otherwise result in contact and thus the possibility of vibration transmission between the second and the can lead first component. The projections and / or are preferably Incisions are provided on the outside and / or inside of the profile. The projections and / or incisions preferably comprise grooves, webs and / or at least a partial bulge and / or at least one Spring element. The cantilevers and / or incisions ensure  easier processing and creating a space between the end face of one inserted into the device or the profile Component and the actual base part or its bottom.

Preferably, the at least one spring element for mounting the second component essentially centrally on the inside of the profile, in particular the base part can be arranged or arranged. This can inserted component are acoustically decoupled from the base part. In addition, swinging in different directions from one Spring element are intercepted, so that only one Spring element needs to be arranged. At least one Spring element preferably has such a spring force that after the Inserting the second component, in particular wall or wall element a gap remains between this and the surface of the component. This does not become advantageous even when the component vibrates filled in to establish contact between the component and the base part, the to be firmly attached to the second component.

The profile preferably has across its cross section different material thicknesses, in particular it is in force-absorbing areas formed thinner. Particularly preferred the at least one leg and / or the tab element has one different material cross-section than the base part, in particular one smaller material cross-section. Such a force-absorbing area is, for example, a tab element. But the legs can can also be formed thicker than the base part, in particular with a Material weakening in the transition area to the base part. This can the spring action and thus the clamping on the wall element to be inserted be improved.

The device or the profile is preferably arranged or procure that non-structural components and the structural components are not  through the application of rigid building materials such as plaster or screed stay in contact. On wall elements or walls and ceilings or floors applied rigid building materials such. B. plaster, extend advantageous only so far over the surface of the profile or the Device away that the profile remains flexible and none Connection between them comes about.

It also causes damage from shrinkage and creep as well thermal changes in length of the building material used Use of the joint insulation according to the invention avoided. Such Otherwise, damage can take the form of tears in the connection area continuous open joints or as plastering of the plaster, which in turn has negative effects on body and airborne noise protection to have.

The profile preferably consists of a dimensionally stable, at least partially elastic material, in particular a permanently elastic material and / or a material with high internal damping. A permanently elastic material is a material that is elastic and hardly becomes brittle over time. A material with high internal damping can advantageously absorb at least part of the vibrations entered. The profile preferably consists of a filled material and / or a material with the inclusion of at least one mineral or metallic material and / or a composite material and / or a material with a reinforcing layer and / or a material that supports the adhesion of plaster and / or paint.

The profile particularly preferably consists of a plastic, in particular extrudable plastic, a polymer or elastomer, in particular a polyolefin, PVC, etc. and / or a metal. Alternatively or additionally, the material of the profile can have CaCO ₃ and / or BaSO ₄ . Plastics such as polyolefins, in particular polyethylene and polypropylene, polyamides and flourished polymers, impact-resistant polystyrene, PVC and the like, are particularly preferably used. The material used is preferably resistant to the higher temperatures and pH values that occur, for example, during plastering, for example temperatures of approximately -20 to + 50 ° C. and a pH value of 14 or preferably withstands these or these without significant structural changes. The material also preferably has good separability, in particular cutability or sawability, in order to enable effortless separation of the profiles to the desired length, preferably corresponding to the joint lengths, on site at the construction site.

Extrusion proves to be particularly useful in the case of the invention Profiles, especially U-profiles, as particularly advantageous. The for plastics, polymers, elastomers suitable for the purposes of the invention etc. can also be made with natural or artificial organic Materials such as B. fibers, cork etc. filled or mineral Contain fillers. The profiles can also be a particular one unilateral reinforcement and / or an insert from a firmer Have material, in particular a metal. Remains advantageous get a sufficient thickness of the elastic material to a Vibration transmission from the non-load-bearing wall to the adjacent one to prevent structural components. The profile preferably has a for the second component included longitudinal rigidity. The The material used therefore preferably has a corresponding one Longitudinal stiffness to prevent the profile or the Device advantageous only by clamping component held prevent.

The legs of the U-profiles are preferably so high that they a firm hold on the non-structural component, in particular Allow wall element or wall. Preferably, the legs of the Device of such a length that it has a firm hold on the  Allow device on the component and / or that after plastering the components a resilient mobility of the device for balancing obtained from, in particular, sound-related relative movements of the components remains. In particular, the length or height of the legs is d. H. the Profile depth, about 10 to 50 mm, in particular 10 to 20 mm.

The device or profile for joint insulation may be preferred not just between two abutting walls or wall elements, a wall element joint, are used, but preferably also for acoustic decoupling of non-structural components, such as walls or wall elements for structural components such as floors or ceilings. Any one, however, is also suitable for this soft-spring connection, which isolates sound from the wall or wall element and floor or ceiling. Especially in Floor area, the desired effect can already be achieved by that a profile made of a suitable material in the form of a tape or Strip is placed, which is in particular significantly wider than that Thickness of the wall and preferably protrudes so far that a more dense Completion of vertical strips is achieved. In contrast for the known method of operation, the compensating band is therefore preferably sufficient at least by the thickness of the edge strips beyond the wall. Since the acoustic decoupling with strips preferably with great care when laying and placing the slabs or stones and the like Construction of the floor with impact sound insulation, screed and covering is carried out when using a profile for the floor area a profile preferred, the clear width between the legs about corresponds to the thickness of the wall.

The walls or wall elements can be made from a wide variety of materials consist, in particular, of bricks, sand-lime brick, concrete, mineral Building materials, etc. have non-load-bearing inner walls of the DIN 4103-1 standard, especially if they are made of a ceramic wall building material, specifically  Bricks exist, wall thicknesses from 40 to 240 mm. The clear expanse between the legs of the device can therefore be advantageous are also in this area. The profiles are particularly in Combination with walls made of fine-pored bricks, preferably those with Hollow chambers provided. These are e.g. B. under the brand CARROBRIC® in the thickness of 40 to 100 mm in the trade. Non-load-bearing interior walls can also from fine porous bricks (Unipor® bricks) of the usual widths of 100 to 240 mm, especially 100 and 115 mm can be built.

In the finished wall or ceiling connection, an air or Compensating gap between the bottom of the profile and the adjacent wall or blanket remain free to allow sliding connections. Preferably, an adhesive is provided that slides in one predeterminable range enables mobility in the range of To allow joint and tear the material there too prevent. For attaching or gluing z. B. mineral glue, Gypsum, cement based on lime cement, etc. can be used.

The material thickness of the device or profile, in particular U profile, d. H. the thickness of the base part and the receiving part, especially the leg, can vary in size and weight Walls or wall elements are made dependent and in particular 1 to 6 mm, preferably 1 to 3 mm.

The length of the profile preferably corresponds essentially to the length the joints of the walls or wall elements. The profiles can be used as Bar stock or roll can be manufactured.

The decoupling system is preferably the respective requirements customized. Changes in geometric dimensions and Material properties are possible.  

The invention also relates to the use of profiles with the previously Features mentioned for acoustic decoupling of non-load-bearing structural components such as walls, wall elements, floors or ceilings and the use of a device or the profile for acoustic insulation of a component joint, in particular Wall element joint, wall joint, wall / wall element floor joint, wall / wall element-ceiling joint, of at least two components, the Device on one of the components, especially a non-load-bearing one Component that can be added on the narrow side and on the surface of the other, in particular load-bearing component can be attached.

In the case of a component provided with the profile or the device, the legs of the device bear under tension at least on lateral outer surfaces of the component and the device is fastened to the component 1 in such a way that between the inner surface of the base part of the device and a narrow end face of the component a distance is maintained. The wall thickness of the component can be chosen arbitrarily.

In order to explain the invention in more detail below Exemplary embodiments described in more detail with reference to the drawings. This show in:

Fig. 1 is a sectional view of a wall or a wall element connection with impact device according to the invention in a first embodiment;

Fig. 2a to 2e are side views of different variants of the device according to the invention, and

Fig. 3 is a side sectional view of another embodiment of a device according to the invention.

In Fig. 1 a connecting wall or wall panel joint is a non-structural wall member 5 and a substantially vertically aligned to load-bearing wall element 2 shown 10th At the joint, a U-shaped device in the form of a profile 1 is inserted between the supporting wall element 2 and the end of the wall element 5 . The profile can, for example, be an elastic plastic profile with an internal width 1 , as shown in FIG . B. 100 mm. The profile 1 has a base part 11 and a receiving part 12 with legs 13 , 14 . The base part 11 of the profile 1 serves to absorb the wall vibrations in the longitudinal direction of the wall. The laterally arranged legs 13 , 14 , which have a height h of in particular 5.5 mm to 20 mm, on the one hand absorb the torques caused by the vibrations of the non-load-bearing inner wall element 5 in the case of rigid connections at the joint and thus prevent them at the joint an excitation of the load-bearing wall element 2 . On the other hand, they prevent the direct contact between a plaster 3 of the load-bearing wall element 2 and a plaster 4 of the non-load-bearing wall element 5 , which could otherwise lead to sound transmission by bridging. An air-filled free space 6 between the base part 11 of the profile 1 and the end 25 of the wall element 5 additionally reinforces the effect of the joint insulation. The free space 6 can be 1.7 mm thick, for example.

Some possible embodiments of the profile 1 according to the invention are shown in FIGS. 2a to 2e and in FIG. 3. The simplest case of a U-profile is shown in Fig. 2a. Here the two legs 13 , 14 are substantially perpendicular to the base part 11 of the profile 1 . The support on the wall element 5 is provided by providing a pretension of the legs, the clear width 1 being in particular less than the thickness of the wall element in order to be able to clamp it.

In the embodiment according to FIG. 2 b, the two legs 13 , 14 are inclined slightly inwards towards the wall element, so that after the profile 1 has been applied to the wall element 5 there is a tension between the legs 13 , 14 and the corresponding part of the wall element 5 . A better hold of the profile on the wall element 5 can thereby be generated.

Fig. 2c shows the profile shown in Fig. 1, which still leaves an air-filled free space 6 between the wall element 5 and the base part 11 after assembly. The legs 13 , 14 each have a greater material thickness than the base part 11 . In the transition region 15 between the legs 13 , 14 and the base part 11 , recesses 17 are provided on the inside 16 of the profile 1 . These serve a better spring effect of the legs, since in particular bending vibrations can be compensated for around this area. The greater material thickness of the legs compared to the base part stems from a better and stronger, but at the same time a spring effect without slipping on the wall element to be gripped.

A further variant of a U-profile, which is also possible in particular for floor and / or ceiling connections, is shown in FIG. 2d. In the original state, the two legs lie on one level with the profile floor. Only during assembly on site, the two legs are z. B. folded up about 90 ° so that in the final state z. B. are approximately at right angles to the base part. An inclination of the legs can also be generated, as shown for example in FIG. 2c.

In the embodiment according to FIG. 2e, the outside 18 and inside 16 of the base part 11 of the profile are provided with webs 19 and grooves 20 forming between them, which enables easier processing. The web 19 arranged centrally on the inside 16 is higher than the two lateral webs 19 . The middle web serves as the actual spring element on which the wall element is attached, the two side webs also being able to absorb vibrations.

FIG. 3 shows a further embodiment of a device or a profile 1 according to the invention. The corners of the profile are rounded, which allows easier manufacture by bending a material strip. Another production variant is extrusion into the desired shape. Tab elements 21 are arranged at the end of the legs 13 , 14 of the receiving part 12 remote from the base part 11 . These are curved and point to the inside of the profile. The tab elements 21 are preferably provided with a thinner material thickness than the legs 13 , 14 and / or the base part 11 in order to show a good spring effect.

A spring element 22 in the form of a curved longitudinal tab is arranged centrally on the inside 16 of the base part 11 of the profile 1 . The spring element has a free leg 23 against which the end face of the wall element 5 to be inserted can rest. The spring element can also have any other shape.

In particular, it is in one piece with the base part. Due to the shape and dimensions of the spring element, the spring force and thus the counterhold against the wall element can preferably be adjusted in order to prevent the base part from touching the wall element. The wall element is pushed between the tab elements 21 such that they abut the surface of the wall element. Vibration compensation can preferably also take place around the transition region 24 between the respective leg and tab element.

The embodiment according to FIG. 3 can be varied, for example, in such a way that an additional insulation layer is applied to the outside and / or inside. This can e.g. B. be formed as a foam. Another possible variation is that instead of the lying spring element 22, the base part is provided with a wave shape, in particular with a central elevation. The end face of the wall element 5 bears against this in turn. The remaining bulges and incisions in the form of wave crests and wave troughs serve to generate a greater spring force.

Studies on the example according to FIG. 2a have shown a damping value of 16.9 dB with a BaSO ₄ material for the profile and a damping value of 24.0 dB with a CaCo3 material. For comparison, a solid connection without the provision of a device according to the invention brings a damping value of 14.6 dB, whereas the cork layer with plank cut (of the plaster) which is common today and which is intended to avoid the possibility of a material connection between the components, in particular walls or wall elements, does one measured attenuation value of 20.7 dB. When the plaster is completely separated, the attenuation value is 30.1 dB. In contrast, with an embodiment of the device or the profile according to FIG. 3, an attenuation value of 37.1 dB has been measured, that is to say that progress can even be achieved compared to the complete separation. The measurements were carried out with a PVC profile of 1 mm material thickness.

In addition to the embodiments described above, numerous other are possible, in particular combinations of the embodiments described above, in each of which a device for joint insulation between abutting components, such as wall elements, walls, etc. is provided, the device being a profile that has a base part for fastening to a first component and at least one receiving part for receiving a part of a second component. For example, the device or the profile can only be U-shaped with curved corners, in particular as variants to FIGS. 2a to 2e. Other variants are possible.
