Installation pipe or downpipe with pipe clamp

The invention relates to an arrangement with pipe clamp and pipe installation or downpipe.

In such arrangements, which are used for holding pipes particularly in buildings or the like., Are between the support ring of the pipe clamp and the thereof enclosed tube as Sound Insulation normally Gummirringe, felt pads or the like. Provided to the transmission of vibrations, in particular sound, by to prevent pipe clamp on the older reverse or attenuate at least.

As Schalldämmittel serving felt pads here have the disadvantage that they get tired with time and are inelastic, so that they can no longer absorb properly the transmission of vibrations or sound.

From document CH-A-664 430 a pipe clamp with two half-rings are known which are interconnected by means of projecting flanges. The half rings are backed by a circumferential, cross-sectionally U-shaped band, which in a U-shaped by two halves existing shell is engaged in turn, the shell in turn bears against the lateral surface of the tube in the mounted state. The band lying between half ring and shell has hemispherical increases to reduce the contact surfaces between half ring and shell and to ensure high sound insulation.

From US-PS 3,606,218 a pipe clamp with an existing of two half-rings is known carrier ring, which surrounds the tube. The carrier ring and arranged on a half-ring support rod are coated with an elastomeric material. At the tube facing peripheral surface strip, axially to the pipe extending Dämmittel are arranged spaced from one another. This Dämmittel are also enclosed by the elastomeric material.

The pipe clamps according to CH-A-664 430 and US Patent No. 3,606,218 is Schell constructions, which are braced against each tube to be fixed. This tension must be such a serious nature that the friction between clamp and pipe is large enough to accommodate all the occurring forces. As a result of stress and as a consequence of the respective pipe not always sits centrally in the clamp attached to a wall as a rule, the location between clamp and pipe insulation material is compressed differently, which is unfavorable in terms of the required insulation of structure-borne sound transmission.

From US Patent 4,046,169 a support for a thin-walled, used in nuclear energy systems pipe is known, in which the respective pipe, a portion is used which is extended outside frustoconical. This truncated cone-shaped extension is positively enclosed to avoid eliminating undesired heat transfer from an insulating material, the purpose of avoiding a direct heat transfer encloses the tube insert with little play.

The invention has for its object to provide a new pipe clamp of the type mentioned, in particular, is always a good vibration and sound insulation between the clamp and the held of the tube can be achieved.

According to the invention this object is achieved by the features of the claim.

Essential for the invention is that of the respective tube enclosing the carrier ring is no longer braced directly or indirectly against the to halternde pipe, but the pipe encloses with a distinctive game and frontally with the interposition of Schalldämmittels the introduced via a provided on the tube supporting flange forces receives. By this interaction of the support flange, Schalldämmittel and the wall mounted support ring generally a surprisingly advantageous Dämmverhalten the pipe clamp is achieved.

The sole figure of the drawing shows an example of a support according to the invention of a downpipe to the invention in a schematic representation.

In the drawing, serving as a down pipe support pipe clamp is shown, which support 11 'is designed as an open axial U-shaped profile. In this U-profile 21 held rubber balls 20 are used in a mesh tubing, a portion of the rubber balls 20 upwards out of the U-shaped support ring 11 'projects. To the space enclosed by the pipe clamp drop tube 12 ', a support flange 24 is provided which rests on the rubber balls 20 so that the drop tube 12' is supported on the supporting flange 24 from the fixed in a manner not shown to a building part carrier ring 11 '.

Instead of the rubber balls 20 may be provided of rubber or an elastic plastic as a spring-elastic elements, other bodies which are formed for example as cubes, stars, angle or the like.

Further, it is possible to use as Schalldämmittel individual elements with different elastic properties from different materials and / or different size and shape.

By a suitable choice of the elastic properties of the rubber balls 20 or other spring-elastic body and the holding sound insulation properties can be suitably formed according to the given requirements.
