Definitions

  • the invention relates to a profile support for a mounting wall, in which, seen in cross section, two substantially parallel legs protrude freely at one end and at the other end merge into a connecting crosspiece and in which tongues are provided over the length and are provided by dividing lines which are on one side a bending area are held and can be bent into a position between the two legs and essentially at right angles to them, with at least one leg of the profile support being covered with building board in the mounting wall and screws screwed into the leg by the building board using their self-tapping screws.
  • the tongue is provided in the crossbar in order to create an opening in the crossbar which has a rounded edge in the bending region and is used for the passage of cables and lines, the tongue being clearly spaced from the ones when bent has both legs.
  • the self-tapping screws are screwed into the leg, they are pressed with force and the leg first evades the screws, causing them to bend. Since the screws are threaded in the building board, the building board bends so that the screws can follow the evading leg. This requires a lot of strength; There is also a gap between the building board and the leg, which does not close completely when the screws are tightened. Due to these circumstances, the outer surface of the wall shell or the building board is no longer planar after screwing on, in particular when the on the leg Joint of two building boards is because this joint forms a step.
  • the profile support according to the invention is solving this problem, characterized in that the tongue is held in length and width in such a way that it extends in the bent state in a supportive manner in the region of the outer leg half between the two legs and the self-tapping screws occurring on the leg in the thread Absorbs forces without significant bending.
  • the profile support according to the invention is stiffened by means of the tongues so that the pressure on the self-tapping screws can no longer bend the leg and the building boards.
  • the area of the tongue which supports the two legs against one another is designed such that it is sufficiently stable and resistant to bending. So there is no bending and no displacement of the building board, i.e. the flatness of the outer surface of the mounting wall is improved. It is also prevented that the profile support mounted at both ends bends due to the screwing over the length.
  • By giving the tongue an appropriate width and length it is assigned a new, supporting function. Since the tongue is firmly connected to the profile support, loose individual parts are avoided.
  • the invention can be implemented on a single-skin or a double-skin mounting wall.
  • the profile support runs, for example, as a profile stand vertically between floor and ceiling or is a horizontal ver running bar.
  • the profile support is usually made of sheet metal, such as steel or aluminum alloy, the tongue remaining in its position by itself after being bent open.
  • the profile support can also consist of plastic, the tongue must be fixed on the legs after bending.
  • the dividing line is, for example, a dividing cut that passes through the material thickness or a fracture line that does not pass completely through the material thickness.
  • the tongues are usually prefabricated during the manufacture of the profile support, but only bent out at the construction site in order to be able to transport the profile supports with legs inserted into one another. If the tongues are provided in the crossbar, cables and lines are led through the openings after the tongues have been bent open.
  • the tongues of the profile support according to the invention are generally provided in the crosspiece, the tongue being supported over its width in each case. Difficulties in screwing on are also avoided here, since no screw can be screwed into the leg in the region of openings in the leg.
  • the profile support usually has a C-profile, the simplicity of manufacture and back Visible strength is an advantage.
  • a Z-profile to provide the bending area at the transition of the cross piece into one leg and to guide the bent tongue to the free end of the other leg.
  • a tongue is alternately guided over the length of the profile support to the free end of one leg and a subsequent tongue to the free end of the other leg in order to support both legs.
  • the bent tongue can also perform its supporting function at a distance from the free ends of the legs. However, it is particularly expedient and advantageous if the bent tongues extend between the free ends of the legs. Free, unsupported leg areas protruding from the support are avoided.
  • the tongue lies flat against the thighs, it can possibly avoid excessive pressure when screwing. It is therefore particularly expedient and advantageous if the tongue is fixed in relation to the leg at the area of contact between the leg and tongue. In this way, an undesired inclination of the tongue while bending the leg is avoided.
  • the determination is made e.g. by snapping the edge of the tongue between two knobs on the leg or by increased friction between the tongue and the leg.
  • a particularly useful and advantageous embodiment is when the profile support is designed as a C-profile with bends on the legs and when the bent tongue extends between the bends of the legs and the maximum width of the tongue is smaller than the width of the Crossbar is. Since the opening caused by the tongue does not extend over the entire width of the crosspiece, its weakening is avoided. The edge of the tongue also has increased frictional engagement at the edge of the bends and is thus fixed in a simple manner.
  • the tongues can be of constant width over their length. However, it is particularly expedient and advantageous if the tongue widens from the bending area to the free end. In the bending area, the tongue only needs to be so wide that it sits sufficiently firmly on the other profile support.
  • the tongue taper reduces the remaining opening and thus the weakening of one leg or the transverse web that occurs. A reduced opening size in the leg also reduces the leg area that cannot be screwed on.
  • the tongues should support the legs against the pressure of the screw, it is theoretically advantageous if a tongue is provided on both sides of each screw. However, it is particularly expedient and advantageous if the distance between adjacent tongues from one another is approximately equal to twice the distance between adjacent screws. On the one hand, this results in adequate support of the legs and, on the other hand, in an even more bearable weakening of the profile support.
  • the invention is not limited to the profile support as it is made. Rather, the invention also covers the profile support processed in the assembly wall, i.e. a mounting wall with this profile support.
  • the profile support (1) is part of a double-skin mounting wall, in one wall shell of which a building board (2) is in continuous contact with the profile support and in the other wall shell two building boards (3, 4) on the profile support (1) a joint (5) educational concerns.
  • the cross-section of the profile support (1) is a C-profile with a cross-piece (6), two legs (7) at right angles thereto, each having a right-angled bend (8), the two bends being directed towards one another.
  • the building boards (2, 3, 4) lie on the outer sides of the legs (7) and are held on them by means of screws (9).
  • tongues (11) are separated at a distance from one another along a dividing line (10), which follow one another at a constant distance.
  • Each tongue (11) passes over a bending area (12) into the crossbar (6) and is bent through 90 ° in the mounting wall.
  • the tongue is at least 1/3 narrower than at the free end and the free end is pushed between the edges of the bends (8), with an inhibiting contact area (13).
