Definitions

  • the invention relates to a sound-absorbing mounting element, in particular for installation and / or components, with a metallic molded part provided for fastening to a supporting structure by means of a fastening element, said molded part comprising the installation and / or component via a sound-absorbing material and optionally a connecting element at a distance from the Supporting structure holds.
  • Fastenings are known, inter alia, in which a rubber damper made of solid rubber is provided between a fastening element to be attached to the ceiling or wall and a suspension for a pipe clamp. These arrangements meet the requirements for sound insulation and temperature resistance, but they are relatively expensive because of the necessary pretensioning of the rubber dampers.
  • pipe fastenings are known, in which the pipe clamps are used to fasten lines that tend to vibrate or transmit noise with damping effect, the clamp band being provided with a rubber profile (Schwnrevers, No. 56/57 - July 15, 1969, pages 54 and 55).
  • the object of the invention is to improve known sound-absorbing elements or insulating parts, in particular mounting elements for building installations, with the aim of providing a sound-absorbing mounting element with an optimal sound-absorbing effect, which is uncomplicated, inexpensive to manufacture, modest in terms of assembly effort and versatile in use.
  • the new mounting element should also be particularly suitable for sound-insulating mounting of light to very light, noise-prone parts in building construction, such as small-caliber pipes, air ducts, false ceilings, etc., the mounting of which has so far mostly not been carried out with sound-absorbing agents, or not consistently enough for cost reasons.
  • the problem is solved with a sound-absorbing mounting element of the type mentioned above in that the metallic molded part has a bore into which a one-piece rubber damper with radial constriction and protrusion on both sides is inserted, and that the rubber damper has a central bore through which the fastening or connecting element is passed through with a spreading effect.
  • the advantage of the inventive design of the new sound-absorbing bracket element is its significant simplicity, for example in comparison with commercially available bracket construction elements, which are designed, for example, as a riveted joint between two metallic molded parts, and in which two-part rubber is used as damping members buffers are interposed.
  • the simpler design in particular with only one metallic molded part and a one-piece rubber damper, enables the desired more economical production.
  • both the hold in the bore of the metallic molded part, in particular in the direction of the force application, is secured, and without any additional means, as well as a basic preload value important for the damping effect, which consequently increases with the load.
  • the mounting element according to the invention is both undemanding in terms of assembly effort and also in its sound-absorbing effect, regardless of the assembly design. It thus fulfills the conditions required by the task with surprisingly simple means, with the additional fact that the new mounting element, with its possible modification forms, is particularly versatile in terms of installation applicability.
  • the rubber damper is a piece of thick-walled rubber hose with a circular cross-sectional shape, the diameter of which approximately corresponds to its length.
  • the term “thick-walled” is understood here to mean a tube profile in which the wall thickness has at least the dimension of the inside diameter.
  • the metallic molded part is a one-piece sheet metal part, preferably angled several times, which has the bore for the rubber damper at one end and a bore for the fastening or connecting element at the other end.
  • the manufacturing costs for this part are minimized considerably due to its uncomplicated design.
  • the functionally important constriction of the rubber piece is also achieved in a surprisingly simple manner in that the diameter of the bore in the molded part is dimensioned smaller than that of the rubber damper by the amount of the constriction, and the diameter of the central bore in the rubber damper is smaller than that by the amount of the spread of the fastening or connecting element passed through.
  • a surprisingly simple type of additional pretensioning of the rubber damper is achieved according to a further proposal with the invention in that the rubber damper is prestressed in the axial direction against the supporting structure by means of a pressure plate pushed onto the fastening element and is bulged on both sides of the constriction, or that it is bulged over one on the Connecting element pushed-on pressure plate is bulged on one side when loaded between this plate and the constriction.
  • the pressure plate prevents the holder from falling apart if the rubber damping part is destroyed, since its diameter is therefore larger than the bore which holds the rubber.
  • the connecting element is designed as a wire hook or sheet metal bracket or threaded rod can.
  • a surprisingly flexible adaptation to local conditions during assembly and thus ease of assembly is further achieved in that either the molded part is attached to the support structure by means of the fastening element via the damper and the connecting element is attached directly to the free end of the molded sheet metal part or that the molded part is attached directly to the Support structure is attached and that the connecting element, preferably in the form of a wire bracket or hook, engages in the central bore of the damper located at the free end of the molded part.
  • the sheet metal part 1 consists essentially of the sheet metal part 1 as the base body and the damper 2.
  • the sheet metal part 1 in the embodiment shown consists of flat steel measuring 30 x 2.5 mm and 115 mm in length. It is angled as a U-profile with the dimensions 30 x 55 x 30 mm and has a hole 4.4 1 in each of the two short legs 3.3 '.
  • the damper 2 is inserted with projections 9, 10 on both sides, and this is excessively pressed into the bore 4, which is smaller relative to the outer diameter, in such a way that a constriction 5 is formed in the elastic body of the damper 2, which - and that is essential to the invention - holds absolutely firmly and securely in its position without any additional aids.
  • the preload caused by the constriction 5 in the damper 2 is further increased by the fact that the fastening element 6 with its shaft 7, the diameter of which is larger by an amount, for example by 1.5 mm, than the bore in the damper 2 into it with an expanding effect is introduced.
  • both the tight fit in the bore 4 of the sheet metal part 1 and the pretension of the damper 2 are further reinforced.
  • This preload increases even more in that the metallic molded part 1 is screwed onto the supporting structure 8 by means of the fastening element 6 via the damper 2, the damper 2 being compressed in the axial direction and consequently building up further preload forces on both sides 9, 10 of its projections 9, 10 bulges in the radial direction.
  • the function of the sound-absorbing bracket is evident from its surprisingly uncomplicated structure as follows: a pipe is attached to the connecting element 11 (not shown), for example via a known pipe clamp, which is subjected to strong flow noises from a flowing medium. These continue in the form of so-called structure-borne sound waves from the pipeline via the pipe clamp and the connecting element 11 into the molded part 1 of the sound-absorbing holder according to the invention.
  • the structure-borne noise-damping effect of the prestressed damper 2 prevents the transmission of the structure-borne sound waves to the supporting structure 8 in a known manner.
  • the sound-absorbing holder according to the invention is fastened directly in the masonry 15 of the supporting structure 8 with a fastening element 6, which comprises a screw 13 and a wall plug 14.
  • the connecting element 11 to which the sound-affected installation part (not shown), such as lines or ducts which transmit pump or fan noise, is fastened, is fastened to the sheet metal part 1 via the damper 2.
  • FIG. 3 a somewhat differently shaped sheet metal part 1 is provided with an otherwise functionally identical arrangement as in FIG. 2, which is suitable for arranging a fastening element with a horizontal axis.
  • the example of this arrangement is intended to show in how simple and varied the subject matter of the invention can be adapted to different local or assembly-related circumstances.
  • FIG. 4 shows an extremely simple and correspondingly inexpensive special version of the subject matter of the invention, which is provided especially for light and lightest mounts of correspondingly light installation parts or components.
  • the sheet metal part 1 is angled in an S-shape and fastened directly with the fastening element 6 in the masonry 15 of the supporting structure 8.
  • the fastening element 6 also consists of screw 13 and wall plug 14 here.
  • the damper 2 is inserted into a bore 4 with a radial constriction 5 and a protrusion on both sides with a constriction 5, 10 on both sides.
  • the connecting element 11 is a simple, threadless wire hook which is inserted into the bore of the damper 2 from above with an expansion effect, that is to say with an oversize.
  • a simple but also light design of the sound-absorbing holder according to the invention is particularly suitable, for example, for light suspended false ceilings or insulation panels, light sheet metal ducts for ventilation installations, etc.
  • the damper 2 is otherwise made from a section of a thick-walled rubber hose and is therefore very inexpensive in spite of the highest quality rubber due to minimal manufacturing costs.
  • the washers 16,16 1 provided in all versions serve both a gu th support of the head or a threaded nut of the fastening screw 6 or the connecting element 6, 11 as well as the securing against the holder falling apart if the damper 2, which is made in particular of rubber, is destroyed, for example, by fire or acids.
  • the diameter of these disks 16, 16 'must therefore be larger than the diameter of the recess 4 in the molded part 1.
  • This flanged edge prevents any sharp sheet metal edges from cutting into the damper 2 made of elastic material, for example rubber or plastic, under higher loads.
  • the molded part 1 can also be formed from a sheet metal wall, which is fastened to a wall in a sound-absorbing manner by a plurality of dampers 2.
  • the cutting of a relatively thin sheet metal wall in the damper 2 can also be prevented by an open sheet metal ring 21 with an angular profile, which is inserted into the recess 4 of the sheet metal part 1.
  • the jacket of the damper lies against the cylindrical part of the sheet metal ring. Since the sheet metal ring is open, it widens when the damper is spread.
  • the radially extending flange 22 serves as a stop and, when properly seated, bears against one side of the sheet metal part 1.
  • the sheet metal ring 21 is expediently pushed over the essentially cylindrical damper 2, and then the damper together with the sheet metal ring 21 is inserted into the recess 4 of the molded part 1.
  • the exemplary embodiment 7 uses a two-part adapter sleeve 23, 24, which is inserted into the central passage of the damper 2.
  • the mutually facing ends of the clamping sleeve parts 23, 24 are conical.
  • the conical part of part 23 comprises the corresponding, but opposite conical part of the other clamping sleeve part 24.
  • the comprehensive part 23 of the clamping sleeve is opened by a slot 25.
  • the clamping sleeve part 24 slides into the slotted clamping sleeve part 23, so that it is widened and presses the only slightly preloaded damper 2 more strongly to the outside.
  • 7 shows the state before the damper is axially preloaded.
  • a stop 27 which is formed by an inner edge of one of the two clamping sleeve parts 23 or 24, the preload that can be applied can be limited to a certain extent.
  • the tapered edge of the slotted clamping sleeve part 23 serves as a stop. As soon as this edge abuts the pane 16, a further prestress cannot be applied.
  • the jacket of the damper can be reinforced, for example, by a steel or nylon fabric or mesh (28).
  • the correct fit of the damper 2 in the recess 4 of the molded part 1 can be ensured by a molded-in, radial step or groove.
  • the elastic damper is forced into the recess 4 of the molded part 1 until the molded part abuts the step or engages in a low groove.
