Definitions

  • the invention relates to a soundproofing insert for mounting rails according to the Preamble of claim 1.
  • Mounting rails are often used in installation and building services.
  • the mounting rails are usually sheet metal profiles with a C-shaped profile and offer a variety of connecting elements a connection option.
  • the advantage of mounting rails is that the connecting elements are everywhere can be mounted along the length of the mounting rails.
  • rail systems are put together, for example from the ceiling depend and serve as a support for cable trays, pipes and ventilation ducts.
  • At Many applications of mounting rails require the rail and the sound-decoupling components attached to or resting on them. This is the case, for example, with rectangular ventilation ducts based on systems from The mounting rails are at rest. Without soundproofing, the noise in the Air shafts arranged to transmit fans and could within one Cause noise pollution in the building.
  • the soundproof rubbers known so far for sound insulation consist of a flexible material and have a flat support part, the longitudinal edges of which Reach over the mounting rail on the side walls. A protruding from the support part The foot section can be inserted into the opening of the C profile rail and engages behind the opening bordering longitudinal edges of the mounting rail.
  • On the surface of the support part run in the longitudinal direction of strip-like beads parallel to each other, which act as supports for serve a ventilation duct.
  • Two of the strip-like ridges are in the area of Longitudinal edge of the sound insulation rubber arranged and support in the assembled Condition on the longitudinal edges bordering the opening of the mounting rail.
  • the other strip-like beads lie over the opening of the C profile rail. All strip-like beads have the same cross-section and have the same Height.
  • a mounting rail resting on a soundproof rubber Ventilation duct is essentially only from the two outer, parallel to the Supported, strip-like beads running along the longitudinal edge of the soundproofing rubber, because the beads above the opening when loaded into the interior of the C-profile rail can dodge.
  • the ventilation duct is often axially back and forth pushed here. Since the weight of the ventilation duct essentially only on the strip-like beads resting on the longitudinal edges of the soundproofing rubber, it can the transverse displacement of the ventilation duct that the longitudinal edges of the Soundproof rubbers are rolled in the sliding direction and the soundproof rubber detaches from the mounting rail. This can lead to the ventilation duct being without Intermediate layer of soundproofing rubber rests on the mounting rail and the intended sound decoupling becomes ineffective.
  • the known soundproofing rubber has a lengthwise one in the foot part Hole on which has an approximately trefoil-shaped cross section. Through the hole the soundproof rubber can be plugged onto a threaded rod. That kind of Sound insulation can be used, for example, for front connections to the Mounting rail may be required.
  • the cross section of the hole only allows use a threaded rod, the diameter of which corresponds exactly to the diameter of the bore is coordinated. This means that the user is able to choose the front Connection elements restricted.
  • the object of the present invention is therefore to provide a soundproofing insert for To improve mounting rails with a C-shaped profile so that even with one Manipulation of a component supported on the soundproofing insert reliable sound decoupling is guaranteed.
  • curling should Longitudinal edges of the soundproofing insert and detachment from the mounting rail on one axial transverse displacement of the component supported on it can be prevented.
  • the Sound insulation insert should be easy to mount on the mounting rail. she should be space-saving and easy to use.
  • the soundproofing insert for mounting rails especially for C profile rails with a substantially C-shaped cross section, consists of a elastic material and includes a support part that has a bottom and has drawn down longitudinal edges and on its contact surface with strip-like Beading is equipped, which is parallel to each other in the longitudinal direction of the support part run.
  • a foot part is integrally formed on the support part, the one on its two Longitudinal flanks each have a shoulder that is the underside of the support part opposite, the foot part in the assembled state within the C-profile rail is arranged and the shoulders bordering the opening of the rail Reach behind the longitudinal edges.
  • the foot part has a lengthwise one Provide hole.
  • An enveloping surface on the contact surface of the The rest is convex, with the strip-like beads on the longitudinal edges of the support part have a greater height than the one enclosed by them Area.
  • the sound insulation insert mounted on the C-profile rail for example a rectangular ventilation duct, not just on the strip-like beads Longitudinal edge but also in the areas in between on the contact surface.
  • the domed areas between the strip-like beads on the longitudinal edges are depressed by the weight of the component and against the longitudinal edges of the C profile rail.
  • the weight of the component is over the entire Support area distributed. This allows the component to run transversely to the longitudinal direction of the C profile rail be pushed without the longitudinal edges of the Roll up the soundproofing insert. This will inadvertently pull the Soundproof rubbers from the C-profile rail by moving the component occurring thrust prevented.
  • the advantageous effect of the inventive design of the sound insulation insert becomes supported by the fact that the contact surface on both sides of the on the longitudinal edges running strip-like ridges fall obliquely to the drawn longitudinal edges. In this way, the longitudinal edges of the soundproofing insert lay down Push the component against the side walls of the C profile rail and act Towards curl up.
  • the envelope surface has Cross section about the shape of an ellipse half.
  • the axial projection forms the Longitudinal edges of the sound insulation insert the main apex of the ellipse.
  • strip-like beads By placing two more parallel between the strip-like beads on the longitudinal edges to these and mutually extending, strip-like beads are arranged, which by a web of material are separated from each other, the height of which is essentially the height corresponds to the strip-like beads on the longitudinal edges, the middle area of the Contact surface of the soundproof rubber when loaded against the opening bounding longitudinal edges of the C-profile rail pressed and braced. This works with a transverse displacement of a component supported by the soundproof rubber against unwanted removal of the soundproofing rubber from the C-profile rail.
  • the foot part of the soundproof rubber better be inserted into the opening of the C-profile rail until it is shouldered Reaches behind the longitudinal edges of the rail.
  • the cross section of the bore in Foot part essentially in the shape of a three-quarter circle, and the hole is on the side of the foot part facing away from the support part by a flexible wall part edged, which is curved into the bore and can be turned inside out, the opposite side in cross section an essentially circular arc-shaped contour having. Due to the flexible wall part, the hole can be Adjust the need for threaded bolts of different diameters. If it is for a front sound-insulated connection is required, a threaded bolt from Inserting a larger diameter is because of the flexibility of the Part of the wall easily possible within a predetermined diameter.
  • the soundproofing insert is on three system areas, which by the longitudinally extending projections and of the arched into the bore flexible wall part are formed, stored. With the largest possible The projections are pressed against the wall of the bore the flexible wall part turned inside out. By making the hole to take is usually formed by threaded bolts of diameter M6 to M10 diameter range used for connections covered.
  • Elastomers prove to be special as a material for the soundproofing insert suitable.
  • the elastomers can be made according to their special sound absorbing and elastic properties can be selected.
  • the support part and the foot part made of elastomers with different properties consist. For example, a somewhat harder material can be selected for the support part be as for the foot part.
  • This coating is an advantage at least on the raised areas of the strip-shaped beads on the support part intended. It can consist of a harder elastomer material or a Be lubricating varnish or the like.
