Definitions

  • the invention relates to a fastening arrangement with an installation element according to the features specified in the preamble of claim 1.
  • Such a device is known from EP 447 936 A3, which has a fastening rail for fastening the installation elements.
  • the mounting rail contains at least two spaced-apart mounting points, the spacing of which is predetermined according to the connection dimensions of fittings or the like.
  • the mounting rail can be covered with rubber or elastomer.
  • Each assembly point contains a number of holes on a bolt circle for the passage of fastening means, in particular designed as screws, so that the angle of rotation of the installation element with respect to the fastening rail can be predetermined.
  • sound bridges can occur, which transmit structure-borne noise from the connected piping system to the building to which the mounting rail is connected.
  • the torque is secured by means of the fastening elements or screws, which, with a correspondingly high torque, come into contact with the bores of the fastening rail and bear against pretension.
  • the elastomer or rubber present in the connection area is compressed inadmissibly, so that sound decoupling is at least considerably restricted there. It is not necessary to emphasize that when connecting a pipeline, a fitting, a corner valve or the like, quite high torques regularly occur on the installation element and its fastening with a fastening rail or the like.
  • the means for sound decoupling were pressed together to an inadmissible extent, which consequently largely lose their function.
  • German published patent application DE 31 48 187 A1 this device containing two pipe elbows each arranged in a housing. These housings have three slots offset by 90 ° to one another, in which one leg of a mounting rail in the form of a U-shaped spacer engages.
  • Each pipe bend is surrounded by a casing made of rubber or the like, which is designed as a two-part shell and can be removed from the respective housing.
  • the housing is closed at the front with a removable cover for pressing on the shell or the casing.
  • the housing and the connection with the U-shaped spacer, as well as the shell which practically completely encloses the pipe bend requires a considerable amount of space and material.
  • junction box for sanitary or electrical installations is known from German published patent application DE 33 10 138 A1, which has a plurality of rings on its outside with grooves in between.
  • a fastening body in the form of a fastening bracket is provided, which can be inserted into the above-mentioned grooves of the junction box in order to adapt the depth of the installation to the respective plaster or tile thickness on masonry.
  • the installation element which is designed as a pipe bend, is built directly into the junction box and, via the junction box and the fastening bracket, which is connected directly to the masonry, sound transmission from the connected fitting or pipe can take place without hindrance.
  • the object of the invention is to further develop the fastening device of the type mentioned in such a way that a functionally reliable connection on the one hand and good sound decoupling on the other hand are ensured.
  • the installation element should be fastened without problems and the possibility of assembly errors should be reduced to a minimum.
  • the fastening arrangement is intended to ensure simple handling and to enable the installation and assembly work to be carried out quickly and safely.
  • the proposed fastening arrangement is characterized by a functionally appropriate construction and ensures problem-free handling during assembly.
  • the installation element is not to be connected directly to a fastening rail or other components that can be connected to the building, but a pane is assigned to the tubular part of the installation element, with a between the installation element and the pane Layer of elastomer or rubber is provided.
  • the disc is connected to the mounting rail or the like.
  • the installation element is connected indirectly via the pane to the fastening rail or the like.
  • the disk in particular designed as a ring, contains a recess in the center, in the area of which the layer of elastomer or rubber is arranged.
  • the tubular part of the installation element engages through the recess, the annular layer of elastomer or rubber surrounding this tubular part. It is not the entire installation element, but only its tubular part surrounded by the elastic layer, so that only a comparatively small amount of elastomer or rubber is required, although complete switching decoupling between the installation element and the fastening rail or fastening body is nevertheless ensured.
  • the disc is preferably annular and / or a flange and contains recesses for screws or other fastening elements.
  • the disk expediently has axially aligned projections which correspond to the associated recesses in the fastening rail or another fastening body, thereby ensuring that it is secured against rotation.
  • both have mutually corresponding contact surfaces, which are preferably designed in the manner of a polygon, such as hexagon or octagon, with the elastic layer lying between them having a corresponding contour.
  • a flange nut or the like is provided in a special embodiment, which is arranged on the other side of the fastening rail than the disk. This flange nut can be screwed onto an external thread of the installation element, a ring or the like made of an elastic material such as an elastomer or rubber being arranged between the flange nut and the rail.
  • Fig. 1 shows an installation element 2, which is designed as a pipe bend and has a tubular part 3 with an external thread 4 at one end. At the other end, the installation element 2 contains an internal thread 6. A fitting, a corner valve or the like can be connected to the external thread 4, while the internal thread 6 is provided for connecting a pipeline, for example for cold or hot water.
  • the installation element 2 is preferably made of a metallic material and is over the tubular part 3 with a fastening body designed as a fastening rail 8 connectable.

  • the radially spaced opposing contact surfaces 16, 18 are arranged with respect to the longitudinal axis 20 in the manner of a polygon, in particular a hexagon or octagon, so that not only a rotation lock is achieved, but also the angular position of the installation element 2 with respect to the fastening body 8 as required can be specified.
  • Decoupling also takes place in the axial direction between the installation element 2 and the pane 10 by a part 22 of the elastic layer 12 which is arranged in a flange-like manner radially outwards.
  • This radial part 22 of the elastic layer 12 lies between a preferably annular shoulder 24 of the installation element 2 and an axial one End 26 of disk 10.
  • a threaded ring 28 is arranged on the external thread 4 of the installation element 2.
  • the threaded ring 28 is designed in this embodiment as a flange nut and the tightening can be done easily with a hexagon wrench.
  • a further elastic layer 30 is arranged, which is designed in particular as a ring and / or as a disk and in turn consists of elastomer or rubber.
  • the fastening body 8 has an opening 32 radially on the inside, through which the installation element 2 is guided in the manner shown.
  • the first elastic layer 12 is extended in the axial direction beyond the disk 10 into the opening 32 with a shoulder 34.
  • the opening 32 is also designed in the manner of a polygon, in particular as a hexagon or octagon.
  • the diameter of the opening 32 or the distance between the radially opposite surfaces or the width across flats of the polygon is expediently larger in the context of the invention than the corresponding values of the recess 14 in the disk 10.
  • the extension 34 is also correspondingly enlarged or protrudes in the radial direction radially outwards.
  • the shoulder 34 on the one hand and the radial part 22 of the elastic disk 10 thus ensure a good fixation of the elastic layer 12 on the disk 10 before the installation element 2 is installed.
  • the extension 34 which extends both in the radial direction and in the axial direction, furthermore reliably prevents direct contact of the installation element 2 on the pane 10.
  • the disk 10 has at least one axial projection 36, which in the embodiment shown here is designed as a knob.
  • An annular projection 37 is also provided.
  • the knob 36 engages in an associated recess 38 of the fastening body 8, so that relative movement in the circumferential direction is avoided and rotation of the disk 10 with respect to the fastening body 8 is achieved.
  • a plurality of such axial projections or knobs 36 and corresponding recesses 38 are expediently arranged distributed over the circumference, so that the disk 10 can be adjusted in different rotational positions relative to the fastening body 8.
  • Fig. 2 shows a view without mounting rail and flange nut and eight axial projections 36 arranged in pairs and offset by 90 ° can be clearly seen.
  • the knobs or axial projections 36 preferably have a conical outer surface, whereby the alignment and insertion into the corresponding corresponding recesses is facilitated.

  • the elastic layer 12 completely surrounds the tubular part 3 of the installation element 2 provided with the external thread.
  • the disc 10 also has recesses or bores 40 for screws or the like. These holes 40 are of no importance when connected to the mounting rail. Rather, the bores 40 allow a further application and a direct connection of the disk 10 on another connecting body or a chipboard, an angle or the like. As indicated by dash-dotted lines, the recesses 14 can also have a rectangular cross section. These recesses can be particularly useful for the embodiment explained below with reference to FIG. 9 for their locking elements and / or for manipulating such locking elements. In the case of the direct connection of the pane and fixing it with respect to a building part, a plate or the like, the installation element can nevertheless be inserted and mounted in the desired rotational angle position after the pane 10, which is preferably designed as a flange, is attached.
