Definitions

  • the invention relates to a profile stand for a soundproof mounting wall, in which two legs are connected at one end by a crosspiece having a material thickness, and in which a close nestability of two profile stand is given by a respective leg of a profile stand between the two legs of the another profile stand is pushed and is close to the one of these two legs and in which the crosspiece is provided with a tongue back forming M-tongue.
  • the profile stand is disposed in the mounting wall between two wall shells, and each of the wall shells abuts one of the legs and is secured to the leg.
  • the mounting wall is to ensure a certain sound insulation, which is why e.g. insulating material is introduced between the two wall shells.
  • a well-known by the practice profile stand of the type mentioned forms a C-profile, in which the cross section by definition runs relatively straight from one leg to the other leg.
  • the C-profile contributes little to the sound insulation of the mounting wall.
  • the C-profile stand is due to its profile profile relatively easy to trim by hand using a pair of scissors, for which purpose the two legs are first cut, then the cross piece is folded in the amount of leg cuts and then the cross piece is cut along the kink.
  • An object of the invention is to provide a profile stand of the type mentioned, which has an improved sound-absorbing function while maintaining the ease of hand cutter cutability.
  • This profile stand combines the improved by the M-tongue sound insulation with an improved, i. tight nestability.
  • the eccentric arrangement of the M tongue can be used with advantage in a wide design of the tongue back and is preferably used in combination with the narrow tongue back.
  • There is a profile stand in which on the one hand provided by a narrow cross-sectional profile profile for easy hand cutter cuttability, and in the other hand, a good Schachtelium and stackability of two profile stand is given by a respective leg of a profile stand between the two legs of the other Profile stand is pushed and is close to the one of these two legs.
  • the good here i. E. narrow or space-saving stackability of the profile stand improves the conditions in the storage and transport of the profile stand and the nestability makes it possible to extend one profile stand by another, by the two profile stand are nested with overlapping end pieces.
  • the good nestability thus simplifies the lengthy fitting of profile uprights or profile stand pieces.
  • the M-tongue is arranged eccentrically offset by at least half the width of the tongue base. This minimum level of eccentricity is necessary for nestability.
  • each leg has a fold at the opposite end of the crosspiece. It is the one profile stand with the shorter leg pushed under the fold of the longer leg of the other profile stand.
  • the eccentric M tongue is spaced from the closer leg by at least the screw penetration dimension.
  • the fferen-Durchdringindu which is also called minimum penetration, is that screw portion which protrudes from the wall shell defining the leg screw from the inside of the leg. The screw should not penetrate into the M-tongue.
  • a profile profile determined by a narrow cross-section is provided for easy hand cutter cuttability, and the cross piece forms on a M tongue a narrow tongue back which is shaped by only one bend and has a maximum back width equal to 4 times the material thickness.
  • This narrowness of the tongue back, in conjunction with the M tongue, i. with the M-shape of the profile a significant improvement in the achievable by means of the profile stand sound insulation. Due to the narrowness of the tongue back and not only due to the M-tongue of the profile stand has an improved sound-absorbing effect in the mounting wall.
  • the simple hand cutter cutability is ensured because the M-tongue can be cut by means of the shears because of the narrowness of the tongue back, after which tongue pieces are cut starting from the tongue back.
  • the hand-scissors cutting of the special M-profile stand according to the invention as well as that of the known C-profile stand runs.
  • the narrowness of the tongue back is important for both improved sound insulation and easy hand cutter cuttability.
  • the M tongue begins at the level of the crosspiece associated end of the legs at a tongue with the two tongue pieces, which merge into one another at the tongue back.
  • the length of the M-tongue extending from the tongue to the back of the tongue is usually at least 50% the length of the legs and a maximum of 100% of the length of the legs. It is important that the tongue back is formed by means of only one bend, ie edging and not, for example, by means of two mutually parallel edgings.
  • the tongue back is the outer contour of the semicircular transition from the one tongue piece to the other tongue piece, wherein the spine width corresponds approximately to the diameter of this transition semicircle. Since the M-tongue in itself causes a weakening of the stability of the profile stand, its legs at the opposite end of the crosspiece usually a fold, which is also given in the known C-profile stand and increases the stability of the profile stand.
  • the M-tongue is created with the narrow tongue back by bending the crosspiece over a sharp edge and then forming a sharp bend on the side of that edge. Since the shaped edge must be slightly rounded for practical reasons, the tongue back, i. the transition between the two tongue pieces on the inside slightly rounded. It is especially expedient and advantageous if the narrow tongue back has a maximum back width equal to 3 times the material thickness.
  • the narrowness of the tongue back is reinforced, which further improves the sound insulation of the profile stand in the mounting wall and further facilitates the hand cutter cutting ability.
  • the M tongue When two tongue pieces project from the narrow tongue back and arranged at an angle of 5-15 ° with respect to each other, the M tongue has a preferable shape in terms of sound absorption and cuttability. If the crosspiece between each of the legs and the M-tongue forms an approximately rectangular transverse portion to the leg, the narrow tongue back and the small angle between the tongue pieces can be simplified.
  • a particularly expedient and advantageous embodiment is when the M-tongue is provided along the narrow tongue back with a series of apertures, which also extend to the two tongues emanating from the tongue back.
  • These, also on the tongue pieces extending breakthroughs also contribute to the improvement of the sound insulation of the profile stand. They facilitate the hand scissors cutting, as in the area of the openings a tongue back is not cut and the scissors can be attached to one of the tongue pieces.
  • the profile stand according to the drawing is installed in a mounting wall according to FIG. 1, which has two wall shells 1, which are respectively placed from the outside to one of two legs 2 of the profile stand 3. There are screws 4 screwed from the outside through the wall shell 1 and the legs 2 and the screw 4 protrudes by a fürdringindu 5 from the inside of the leg in the profile stand.
  • the profile stand is assigned a center line 6.
  • Each leg 2 carries at one end a fold 7 and the two folds 7 project towards each other. At the opposite ends of the folds go the two legs 2 in cross piece 8 into each other, which is provided with an M-tongue 9.
  • the bends 7 arranged opposite crosspiece 8 then forms at each leg 2, 2 'a transverse region 10, 10', of which one is 10 larger than the other 10 ', so that the M-tongue 9 with respect to the center line. 6 is arranged off-center, ie of the one leg 2 has a greater distance than from the other leg 2 '.
  • the profile stand 3 is arranged for tight nesting with a same profile stand 31 to each other so that the legs 2, 2 'with the folds 7 to each other and that the longer leg 2 of a profile stand 3 the shorter leg 2' of is associated with other profile stand 31.
  • the two M-tongues of the two profile posts 3, 31 are sufficiently far offset from each other.
  • the two profile posts 3, 31 are nested tightly or closely, in each case one of the legs 2 'of the one profile stand rests on the other leg 2 of the other profile stand from the inside.
  • the two M-tongues do not touch each other.
  • Each M-tongue 9 forms at the transverse regions 10, 10 'a tongue 11, which is formed by two tongue pieces 12 which are arranged at an acute angle 13 to each other.
  • the two tongue pieces 12 merge into one another at the end opposite the tongue foot 11 via a tongue back 14.
  • the tongue back 14 has a spine width 15 which is measured on the outside and which is larger as the material thickness 16 of the profile stand.
  • the tongue back 14 forms on its inside a kink-like relatively sharp bend 17.
  • the tongue back 14 is provided with a series of short apertures 18, so that only short bridges remain 19 of the tongue back itself.
  • the apertures 18 are punched in the case of flat material as round holes and also extend to the tongue pieces 12th
  • two profile stands are stacked for transportation or storage, i. save space and pushed together relatively loosely.
  • the fold 7 of an outwardly disposed leg 2 'of one profile stand ends in front of an adjacent inwardly disposed leg of the other profile stand.
  • each of the folds 7 of a profile stand distance from the transverse regions 10, 10 'of the second profile stand While in nested profile uprights according to FIG. 4 each have a longer leg of a profile stand and a shorter leg of the second profile stand must be assigned to each other, this can be optional for stacked profile uprights, as in stacked profile uprights as shown in FIG. 6, the two shorter legs of the two Profile stand and the two longer legs of the two profile stand can be assigned to each other.
