Description

The invention relates to a sound-absorbing element having a planar base body, wherein the base body has an outer wall and an inner wall arranged parallel to the outer wall and a cavity formed between the outer wall and the inner wall for introducing a Dämmmaterials, wherein the base body along at least one substantially between the outer wall and the inner wall formed in a peripheral region has a profiling and wherein the profiling is formed for producing a non-positive and / or positive connection with a correspondingly formed profiling of another adjacent Schalldämmelements.

A sound-absorbing element of the type mentioned is for example from the DE 44 14 201 C1 known. Specifically, this document shows a sound-absorbing element with a flat base body, wherein the base body has an outer wall and an inner wall arranged parallel to the outer wall. Between the outer wall and the inner wall, a cavity for introducing an insulating material is formed. The main body has profiling along opposite longitudinal sides. The profiling is designed for producing a non-positive and / or positive connection with a correspondingly formed profiling of a further adjacent Schalldämmelements.

The known soundproofing element has a profiling on opposite longitudinal sides, which consists of angled parts to form a positive connection. The parts are hook-shaped, so that a connection of adjacent sound-deadening takes place by engaging behind correspondingly formed parts of the adjacent Schalldämmelemente. The cross-sectional shape of the profiling is essentially zigzag-shaped. The hook-shaped parts allow a secure positive connection of adjacent sound-absorbing elements.

In the known sound insulation is problematic that, although a secure connection between adjacent sound insulation is possible, however, that an exchange of individual sound insulation usually only after a complete disassembly of a wall formed from individual sound insulation or a structure formed by sound insulation is possible. Such an exchange may not only be necessary in the event of damage to a single sound-damping element, but also in the event of a change in design of a sound-deadening element due to changed boundary conditions. Consequently, the known soundproofing element in handling is impractical and leads to the known soundproofing element at great expense and thus high costs in the case of a required exchange.

The present invention is therefore the object of a sound insulation of the type mentioned in such a way and further, that a simple handling and in particular a simple replacement of individual sound insulation is made possible by a construction of assembled sound insulation elements with simple design means.

According to the invention the above object is achieved by a sound-absorbing element with the features of claim 1. Thereafter, the sound-absorbing element is configured and further developed such that the profiling has such a curved, curved, polygonal or polygonal cross-sectional shape that a Wegschwenken the Schalldämmelements - from a connected to the adjacent Schalldämmelement position - is made possible away from the adjacent Schalldämmelement.

In accordance with the invention, it has first been recognized that the above object is achieved in a surprisingly simple manner by skillful design of the profiling of the body. In further inventive manner has then been recognized that even without hook-shaped engaging parts a secure connection of adjacent sound insulation is possible. For this purpose, the profiling on such a curved, curved, polygonal or polygonal cross-sectional shape that a Wegschwenken the Schalldämmelements is made possible by an adjacent Schalldämmelement, from a connected to the adjacent Schalldämmelement position. By such a curved, curved, polygonal or polygonal cross-sectional shape, a secure positive connection of adjacent sound insulation elements with correspondingly formed profiles is possible. The curved, curved, angular or polygonal cross-sectional shape allows a safe investment of two adjacent sound insulation elements to each other both in a present within the plane of the sheet-like soundproofing elements and in a direction perpendicular thereto. By the possibility of Wegschwenkens a Schalldämmelements from a connected with an adjacent Schalldämmelement position replacement of a single Schalldämmelements is very simple, since adjacent Schalldämmelemente can remain in position and only the soundproofing element to be replaced from the connected position can be swung out of a generated by Schalldämmelemente arrangement ,

Consequently, with the sound insulation element according to the invention, a soundproofing specified, in which a simple handling and in particular a simple replacement of individual soundproofing elements of a structure assembled together soundproofing with structurally simple means, namely only by skillful design of the profiling is possible.

Depending on the arrangement of the Schalldämmelements in an arrangement of several sound-absorbing elements, it is sufficient if the sound-absorbing element has a suitable profiling on only one longitudinal side. This is the case when the sound-absorbing element adjoins one side of the profiling on a wall or at a right angle to another sound-absorbing element. Such a right-angled connection can be present, for example, if the sound-absorbing elements form, for example, a rectangular envelope of a spatial area. However, if a sound-absorbing element is to form a connection to two further longitudinal sides, each with a further sound-damping element, the profiling can be formed on two opposite longitudinal sides of the base body. In this case, the profiling on the one longitudinal side may be formed quasi-complementary to the profiling on the opposite longitudinal side of the Schalldämmelements.

In a soundproofing element, which does not have to enter into a connection with a further soundproofing element on opposite longitudinal sides, the base body may be flat on the longitudinal side opposite the profiling or may have no profiling.

In order to allow a safe Wegschwenkens the Schalldämmelements from a connected position, the cross-sectional shape may be substantially convex or substantially concave, the convex cross-sectional shape can engage with a correspondingly formed profiling another adjacent Schalldämmelements which is concave. Conversely, a concave cross-sectional shape may be associated with a corresponding convex cross-sectional shape. In the present case, essentially convex or substantially concave means any shape of curvature, bending, angularity or polygonsity, provided that the cross-sectional shape is profiled only in a manner suitable for a swiveling away in deviation from a plane configuration. In other words, in the present case, an angular or polygonal cross-sectional shape may also be considered substantially convex or substantially concave.

With regard to a concrete and very simple cross-sectional shape, the cross-sectional shape may be circular arc. Here, too, it is merely necessary to ensure that the profiling has such a cross-sectional shape that pivoting away the sound-absorbing element from a position connected to an adjacent sound-insulating element is possible.

A further particularly simple cross-sectional shape can be formed by an angular cross-sectional shape resulting from a profiling having an orthogonal to the outer wall surface and a subsequent to this surface further surface which is arranged inclined or angled to the orthogonal surface. As a result, a particularly simple profiling is realized, which allows a safe swing away in the event of replacement of a Schalldämmelements.

In a further advantageous and simple embodiment, the profiling an orthogonal to the outer wall extending surface, adjoining this surface further surface which is arranged inclined or angled to the orthogonal surface, and at least one subsequent to the further surface further surface have, which is arranged inclined or angled to the further surface, wherein the at least one further surface is inclined or angled relative to the further surface in the same direction or direction of rotation as the further surface relative to the orthogonal surface. By such a design of the profiling a polygonal cross-sectional shape is formed. In other words, such a profiling has three or more surfaces which are arranged in the same direction of rotation relative to one another by angling about mutually parallel axes.

With regard to a particularly stable and simple embodiment of the Schalldämmelements the further surface or the at least one even further surface may extend to the inner wall. In other words, can be realized by the profiling a tight or closed connection between the edges of the outer wall and the inner wall. As a result, for example, the penetration of water and possibly other fluids into the cavity can be prevented.

With regard to a simple construction of different structures or structures of sound insulation elements, the base body, preferably on or in the inner wall, at least one C-rail and / or angle and / or tabs for mutual bracing of the main body or sound insulation and / or for attachment of other components , for example, handrails or Railing, exhibit. It is considered that the sound insulation according to the invention can form both a wall and a roof structure. Especially with roof structures handrails or railings are often to realize. For this purpose, suitable angles and / or straps formed on the main body can be particularly advantageous. A C-rail may be particularly useful in the arrangement of soundproofing elements on substructures.

With regard to a particularly stable embodiment of a Schalldämmelements a preferably riveted trapezoidal sheet can be arranged in the cavity. This stabilization of the Schalldämmelements by the introduced into the cavity trapezoidal sheet is particularly advantageous when using the soundproofing elements in a roof construction, as can be due to the stability realized walkability of the roof structure.

Usual basic body may be formed substantially rectangular or square. Deviating special forms are also possible in individual cases, whereby in this case is to be turned down specifically to the particular application.

Of course, the sound insulation element according to the invention is particularly easy to handle not only when replacing already installed sound insulation, but also in the construction of a construction of several sound insulation, as attaching a Schalldämmelements is already possible to existing sound insulation elements by pivoting in a simple manner. In one embodiment of a Schalldämmelements with an inserted trapezoidal sheet large field widths of at least five meters can be achieved. In this case, a sheet thickness of an outer wall or inner wall of often only about 1 mm is sufficient.

Individual assembled sound insulation elements can form, for example, a sound hood, which can surround a noise-generating machine. In a typical embodiment of a Schalldämmelements an outer wall may be formed by steel sheet in a thickness of 1 to 1.5 mm. A trapezoidal sheet introduced into the cavity could have a thickness of 0.5 to 0.75 mm. Mineral wool can furthermore be arranged in the cavity. The inner wall may be formed by a perforated plate, which is 0.8 to 1 mm thick.

When using soundproofing elements in the roof area, the elements can be additionally provided on both sides with interlocking folds, which prevent the entry of water and thus ensure a rain impermeability. However, these folds do not affect the disassembly of individual elements. Large, free spans can be achieved by the individual sound insulation elements on the one hand by the special geometric shape, in particular the profiling, and on the other hand by internal trapezoidal sheets or trapezoidal profiles. To attach the sound-absorbing elements to, for example, a load-bearing steel construction, the sound-damping elements can be clamped via C-rails, which lie, for example, on the inside of the sound-absorbing elements, at least at two points on pre-positioned tabs located on a steel construction. The C-rails can be positioned at any suitable position of the Schalldämmelements so that multiple attachment to an existing steel structure can be done or the sound insulation can be assembled into a stable, self-supporting composite. Here, for example, continuous carrier or flat iron can be clamped on the C-rails. It can then be dispensed with a supporting steel structure.

Soundproofing elements used as roofing elements may have additional fastening tabs to secure railing and handrails thereto. Such railings and handrails would then not necessarily be attached to a steel structure. Passages or passages through the sound insulation and associated leaks could be avoided in this way.

Due to the pivoting of individual soundproofing elements, such a soundproofing element could also be used as a door in a corresponding construction of a plurality of soundproofing elements, such a door not requiring a frame due to the inventive design of the profiling. This forms a very practical application for a sound-absorbing element according to the invention.

There are now various possibilities for designing and developing the teaching of the present invention in an advantageous manner. For this purpose, on the one hand to refer to the subordinate claims and on the other hand to the following explanation of preferred embodiments of the invention with reference to the drawings.

In the in the 1 and 2 embodiment shown has the profiling 6 an angular cross-sectional shape. This angular cross-sectional shape is characterized by two mutually angled surfaces of the profiling 6 educated.

This form of profiling 6 allows a safe swinging away a Schalldämmelements of an already made structure, as shown in the 1 and 2 is shown by broken lines of a weggeschwenkten Schalldämmelements. This soundproofing element can be used as a door 7 for access to the space formed by the structure.

That as a door 7 serving soundproofing element has profilings 6 on two opposite long sides 5 of the basic body 1 on. The at the door 7 serving soundproofing element adjacent sound insulation elements each have on one longitudinal side 5 a profiling 6 on, at the door as the door 7 serving soundproofing directed longitudinal side 5 , At the door 7 remote longitudinal side of this sound insulation is no profiling 6 provided or is the profiling 6 just trained. This is because these are next to the door 7 arranged soundproofing elements at their door 7 side facing away from in this embodiment are arranged perpendicular to other sound-absorbing elements and are therefore connected in other ways with these other sound-absorbing elements.
