Description

The The invention relates to a stand element for the Structure of partitions and the like according to the preamble of claim 1 and a system for the construction of Partitions.

partitions in lightweight construction allow in a simple way even without elaborate masonry, the design, in particular Redesign of all types of spaces. Therefor Become special steel stand or stand elements installed on the desired areas, in particular the Recording of sound insulation panels (possibly also thermal insulation panels) serve and on the outside then in particular plasterboard be attached to additional separations z. B. between existing masonry. Usually The gypsum boards are as close as possible to their edges connected to the stator element or the flanges. Of the Distance of the fastener to the respective edge but should be chosen so that a tearing of the plate edge avoided becomes. For this reason, in processing a central arrangement of the edge of two plasterboard panels established on a supporting flange as standard.

The mostly upright stands have very different Profile cross-sections on, z. B. U, C, M or Ω profile cross-sections, with a central bridge and flanges protruding from it. The flange thus runs along the bridge and extends cantilevered off the bridge with its width. The interior (hollow) space of Ständerelements, so the profile cross-section is designed to Insulation material for sound insulation (if necessary also heat insulation), z. B. of mineral wool formed sound insulation panels.

According to DIN standard ( DIN 18 182 ) known stands with the above profiles with flange widths of 50 or 35 mm or with even smaller flange widths are formed.

by virtue of The lightweight construction are special requirements for the materials in terms of heat and especially with regard to sound insulation put. So be for the construction of partitions often special plasterboard and special sound insulation panels used. It is also possible, in addition to the partition walls attachment shells to install a cheap Soundproofing measure to achieve. In addition, suitable for To ensure connection seals in order to connect in the connection areas (z. B. between partition and existing wall) sound bridges to avoid.

With The known devices, it is difficult to a high degree of soundproofing a reach ready-mounted wall.

It Object of the invention, a stator element and a system for the construction of partitions and the like provide, with which in a simple manner and with simple means a good sound insulation of the assembled partition is reachable.

These Task is achieved by a stand element according to claim 1 and solved by a system according to claim 7.

In particular, the object is achieved by a stator element with a U, C, M or Ω profile cross section from a central web and flanges projecting from the web on both sides in that the flanges have a width (this is the extent of the flange projecting from the web). from 55 to 90 mm. It is also possible, depending on the field of application, to provide unequal flanges in the above-mentioned dimensional range. The uprights can be provided both as wall profiles (eg CW profile) or as ceiling profiles (eg CD profile). Consistent with footnote b of Table 1 of DIN 18 182 are understood here by unequal-sided flanges with a difference of the flange width of at least twice the sheet thickness.

One essential point of the invention is that by means of the stator element now wide, but still stable flanges for fastening the partition elements are provided.

Prefers the flanges have a width of 60 to 75 mm, particularly preferred of 60, 65 or 70 mm.

This dimensioning of the flanges is based on the finding that, when the fastening means for attaching the plasterboard to the flange or flanges are located as far away as possible from the web (and towards the free flange end of the respective flange), the assembled partition With the stator elements according to the invention shows a much better sound insulation behavior and in particular the sound insulation level is significantly improved, as would be possible with conventional uprights elements. That is, the improved sound insulation in lightweight constructions of the type described above is due to the fact that the flange is increased, leaving more room for the arrangement of the fastener, which can now be fastened just further away from the web. Usually, the known flanges have a width of 35 or 50 mm. Here, the fasteners are forced to position near the bridge, resulting in a less favorable sound insulating effect of the finished wall leads.

It However, it has also been found that too wide flanges due to a then certain instability of the over-spread Flanges vibrations can occur, in turn unfavorable effect on the soundproofing level.

In Another preferred embodiment is the gypsum plasterboard in the region of its edge by means of a screw connection as a fastening means, can be arranged on the flange near the free flange end such that in the case of two gypsum plaster boards arranged on one flange at a distance from one another a so-formed joint as close to the free end of the flange is arranged (the flanges are formed such that usually each two gypsum plaster boards in abutment with each other on a flange can be arranged and as close to the edge as possible can be fastened to the flange). It is suitable for this z. B. Drywall screws that assemble in a simple manner to let.

alternative can the plasterboard by means of nails, staples or adhesives are attached to the upright profile. in the Case of the adhesive attachment is for realizing the invention narrow adhesive strip, which should not be wider than about 1 cm, to be attached at the same place as a line attachment. Especially suitable is an adhesive bead. In addition, the adhesive bond with other fasteners, especially screws, for the Fire can be upgraded to premature failure to prevent the attachment.

The enlarged according to the invention Flange width thus allows the attachment of the plates so close to the impact that the fasteners as far as possible from the web of the stand element, as described above, resulting in an improved soundproofing effect is reached.

Farther it can be provided that the stator element with at least a substantially perpendicular to the profile cross-section Beading is formed for stiffening the stator element. In the case of several, in particular arranged on the two flanges Beading is a mirror-symmetrical arrangement to the symmetry axis of the Profile cross-section with isosceles profile cross sections especially prefers. Furthermore, the flange ends (web-facing Side) have flaring or (for ceiling profiles) be formed with suspension guides.

Preferably is the stand element for the construction of a single stud wall, a double stud wall or an attachment shell. at Einfachständerwänden are the stator elements preferably Planked with plasterboard on both flanges. Double stud walls have z. B. two juxtaposed stator elements, in each case their outer sides are covered with plasterboard are. Also intent shells are planked on one side and z. B. arranged in front of an existing wall. The invention enlarged flanges always allow one improved soundproofing.

ever according to size, a complete partition has several successively arranged stand elements, which as End and arranged as intermediate elements for the wall structure are. The individual end or intermediate elements for a Double column wall are z. B. arranged two side by side Stand elements formed.

In Another preferred embodiment is the upright element made of unalloyed steel, preferably with a zinc coating as corrosion protection, educated. This is a stable and durable substructure given for the installation of the plasterboard.

The The above object is further provided with a system for solved the structure of partitions and the like, comprising at least one upright element as described above, with a web and flanges arranged thereon, at least one partition element, in particular a gypsum plaster board, which on at least one flange the stand element can be arranged and fastening means for Attaching the partition wall element to the at least one flange.

The System thus includes the described stator elements and the thereto about fastening means, preferably over a screw connection, disposable partition plates, in particular Plasterboard. The plasterboard will be close to the edges (or near the impact with two meeting each other Plates) mounted on the respective flange, due to the widened flange width for the sound insulation the prefabricated wall cheaper (larger) Distance of the fasteners to the web of the stand element can be complied with.

The System can also be formed in particular of mineral wool sound insulation panels include, which are receivable in the stator element. For this the design of the profile cross-section is suitable. The sound insulation panels can also for the thermal insulation be designed.

Depending on requirements, the system may comprise a plurality of uprights elements (wall elements and / or ceiling elements or profiles), so that with the stator elements according to the invention a separation wall can be constructed, which has very good properties in terms of sound insulation.

Further Embodiments of the invention will become apparent from the dependent claims.

following Embodiments of the invention will be described with reference to figures explained in more detail. Hereby show:

4c a diagram showing the weighted sound reduction dimension of a partition wall area when using a known stator element.

In The following description will be for the same and the same acting parts the same reference numerals used.

1 shows an embodiment of a stator element according to the invention 10 with C-profile cross-section, for the construction of a partition or the like, in a plan view. The upright element 10 is for example used as a wall profile (CW) and has a central web 20 on, in this embodiment, with two beads 23 . 24 for stiffening the upright element 10 is trained. At the jetty 20 are two-sided, approximately at a 90 ° angle, two flanges 21 . 22 arranged so that ultimately the C-shape of the profile is formed. The flange ends have flanges.

The Flanges could also be at a different angle from the dock abkragen, so that, for example, a trapezoidal Profile results.

uprights be for the construction of a partition or the like used, wherein on the stand element partition wall elements or plates are fastened to finally a complete partition to obtain.

According to the invention, it is now provided, the flanges 21 . 22 very wide (width b, wider than is the case with known stator elements), so that fasteners 40 . 41 , in particular screws, for fastening the partition wall elements to the flanges 21 . 22 as far as possible from the jetty 20 away, so from the jetty 20 moved away, can be attached. This improves the sound insulation of the fully assembled partition. A sound-absorbing effect generating arrangement of the screws would not be possible in known elements due to the narrow flange widths.

In 2 is the stator element according to the invention 10 (or system 1 ) having a partition wall (cutout) arranged thereon, wherein the partition wall consists of several plasterboard panels 30 . 31 consists. Here is a section of two plasterboard panels are shown, which are arranged in abutment against each other. The representation is very schematic and is intended only as the principle of the system 1 show.

The flange width b is increased over known elements, wherein the flanges 21 . 22 of the C-profile with 55 to 90 mm, preferably with 60 to 75, particularly preferably with 60, 65 or 70 mm are formed. Schematically, the fasteners 40 . 41 shown, here z. As screws, with which the plasterboard 30 . 31 in the area of their edges, here near the impact, to the one flange 21 are fixed (the partition plates are usually always close to the edge, preferably at a defined distance from the edge, attached to the flange).

Also on the opposite flange 22 Partition panels can be attached. The interior (hollow) space of the stand element 10 is adapted to receive insulation material for sound insulation (not shown), for. B. formed of mineral wool soundproofing panels. These can be designed or designed such that they also serve the thermal insulation.

In the 1 indicated beads 23 . 24 are in 2 for the sake of simplicity not shown.

This in 2 shown stand element 10 is here as the middle part of a wall system 1 provided, but can also be arranged on an existing wall. The upright element 10 would then z. B to the existing masonry by means of a connection seal.

3 shows by way of example a logarithmic diagram for the determination of a weighted sound Dämm-measure R _W (in decibels, dB) for a partition wall area, ie for a wall system, when using a stator element according to the invention 10 with CW profile (C-wall profile). Shown is the result of a measurement of the airborne sound insulation, wherein a double metal stud wall with about 70 mm flange width was used. The flanges were double-layered with approximately 12.5 mm thick gypsum plasterboard to finally 10 m ² wall of the test to undergo. Further, a mineral wool insert was used as described above.

to Fixing the plasterboard to the flanges were screws used that positioned as far away from the dock as possible are. The plates are usually as already described attached to the respective flange near the edge. Indeed Make sure that the screws are only so close to the edges the plasterboard are arranged that a tearing the plates at the attachment points is avoided.

On the ordinate is a sound reduction index R (in decibels, dB), on the abscissa is a third-octave center frequency f (in hertz, Hz). The sound reduction measure describes the capacity of a component or medium (here the partition area), to mute the sound.

For the measurement, the sound reduction index R for the individual frequencies is measured in thirds intervals and the mean value is formed in each case. The values are entered in the diagram (the curve shows that the sound insulation of the wall system depends on the frequency). The curve thus determined is essentially brought to coincide with a predetermined reference curve according to rules which are not explained in more detail here. Finally, to obtain the weighted sound reduction index R _W , the value obtained by the "shifted reference curve" at 500 Hz is determined. The weighted sound reduction index R _W is corrected by spectrum adjustment values (in this case) C and C _tr . These values take into account the frequency characteristics of different sound sources, with the sound reduction index being reduced by this value. The evaluation method for the weighted sound reduction index R _W just described is a standardized test which is familiar to the person skilled in the art.
