Definitions

  • the invention relates to a method for producing a reinforced profile element for supporting at least one wall partition, in particular at least one drywall plasterboard partition according to claim 1.
  • WO 2012 143381 discloses a profiled element and method for producing a profiled element.
  • US 2010 0229501 describes a steel stud construction member for use in supporting structures and having openings and reduced heat transfer characteristics.
  • US 4,838,002 discloses a clip fastener for securing a partition wall to a ceiling T-Bar framework.
  • US 2,802,551 describes a unit of integral form that is constructed to provide a rigid support for a plurality of spaced apart and parallel strips.
  • US 2,903,753 describes a clip which is adapted to engage various components usually employed in a partition construction.
  • EP 0 364 768 A1 relates to a partition wall unit.
  • Profile elements as a carrier structure for the construction of walls, in particular walls consisting of gypsum plasterboards are known. Such profile elements are supporting components (e.g. studs) which absorb and transmit forces resulting, e.g. from adjacent wall partitions and/or forces resulting from external conditions, such as loadings, impacts, acoustics, etc. Profile elements should have a minimal weight and sufficient static properties, in particular a sufficient stiff ness and stability.
  • document WO 2008/087009 A1 suggests a profile element with a bridge region (web) comprising a plurality of support braces and connecting braces. The connecting braces are arranged between the support braces being oriented substantially in the longitudinal direction of the profile element.
  • the structure of the bridge region of document WO 2008/087009 A1 allows the production of a comparatively low weighted profile element with sufficient static properties.
  • a method for producing a reinforced profile element with a web and at least one flange for supporting at least one wall partition, in particular at least one drywall plasterboard partition comprises in particular the steps of:
  • a key aspect of the present invention is the formation of a cut out and the utilisation of the cut out (or a corresponding portion being detached or detachable because of the cut out) as reinforcing structure.
  • the cut out is preferably a service cut out for enabling a service person to access regions within the profile element.
  • the service cut out is used for leading (e.g. signal and/or power) lines into and/or through the profile element.
  • the service cut out may be used for inspections, e.g. endoscopic inspections.
  • the use of a cut out, in particular a service cut out, as reinforcing member results in a very light, stiff and rigid profile element.
  • the cut out may have an area of at least 5 cm 2 , preferably 10 cm 2 , further preferably 20 cm 2 .
  • An upper limit of the area of the cut out may be 500 cm 2 , preferably 300 cm 2 , further preferably 100 cm 2 .
  • the cut out has a four sided shape, in particular a rectangular shape. Other shapes (e.g. polygonal, circular, triangular or oval) are possible.
  • the term "reinforcing" should preferably mean that a stiffness, in particular bending stiffness and/or the stability, in particular torsional stability and/or bending stability, of the profile element main body is enhanced.
  • the (gypsum) plasterboard is preferably a sandwich-type plasterboard with a gypsum layer between two sheets of paper and/or a fibre-reinforced plasterboard.
  • at least a portion of the reinforcing element is integrally connected with the profile element main body, in particular hinged, wherein the reinforcing element is preferably bent and/or folded for transferring at least a portion of the reinforcing element from the first position to the second position.
  • reinforcing element and profile element main body preferably form (still) an integral body.
  • the reinforcing element is (completely) detached from the profile element main body (after step b).
  • the reinforcing element can be cut out from the preliminary profile element and be, then, bent and/or folded in a certain shape for a reconnection with the profile element (or profile element main body). This means that the complete structure can be precisely adapted to the requirements of the use of the profile element.
  • the shape of the reinforcing element is changed (during step c).
  • the shaping may imply a bending and/or folding and/or cutting and/or thermal treatment (preferably, the reinforcing element is not heated in step c). It is, hence, possible to adapt the reinforcing element synergetically to the profile element main body in order to improve the stability thereof.
  • the shape of the reinforcing element may be kept constant. For example, it is possible to simply turn or rotate the reinforcing element from the first to the second position. Moreover, it is possible to completely remove the reinforcing element and to reconnect the same reinforcing element to the profile element main body without changing the shape thereof. In any case, the production process is very simple and excellent static properties are achieved.
  • the arresting mechanism is a snap-in mechanism.
  • the arresting mechanism may comprise at least a recess and/or at least one projection being provided at the reinforcing element and/or the profile element main body.
  • the profile element main body comprises a projection which may be urged backwards by an edge of the reinforcing element, wherein the projection of the profile element main body snaps in its original position when the edge of the reinforcing element exceeds a certain point (e.g. a tip of the projection).
  • a projection is arranged on the reinforcing element.
  • the profile element main body and the reinforcing element can be formed and arranged so that a movement (rotation) of the reinforcing element widens the profile element main body until the profile element main body snaps back in its original position.
  • a "widening" of the profile element main body is preferably an enlargement of an angle between two flanges or one flange and a web of the profile element main body.
  • the reinforcing element comprises one or two recesses corresponding (e.g.) with edges of the profile element main body. In any case, the connection between the reinforcing element and the profile element main body is very simple and reliable.
  • the method comprises the steps of providing a plurality (e.g. at least two, at least three, at least five or at least ten) cut-outs, wherein the cut-outs are preferably positioned at regular intervals and/or preferably formed so that their alignment alternates.
  • a plurality e.g. at least two, at least three, at least five or at least ten
  • the cut-outs are preferably positioned at regular intervals and/or preferably formed so that their alignment alternates.
  • the profile element may be a Z-, C- , T- or I - profile element. Other geometric structures are possible (e.g. a CT-stud).
  • the cutout is provided in a web (bridge section) of the profile element.
  • the cut-out may be provided on a flange section.
  • the reinforcing element being made of the cut-out can connect a web with a flange section or a web with two flange sections or one flange section with another flange section.
  • At least a portion of the reinforcing element may be rotatable.
  • a rotation axis is preferably perpendicular or parallel to a longitudinal axis of the profile element.
  • the rotation axis is parallel to the profile element.
  • the profile element is a U- or C-profile element, it is preferred to have the rotation axis perpendicular to the longitudinal axis of the profile element.
  • the reinforcing element may comprise a clip member.
  • the clip member has preferably a U-shape (in cross section) and/or at least one recess. Such a clip member can realiably be reconnected with the profile element main body in order to obtain a rigid and reinforced profile element.
  • the cut-out is a service cut-out. Then, the cut-out serves two functions resulting in a simple and light weighted reinforced profile element.
  • the reinforcing element engages and/or locks the flanges of the profile element.
  • the reinforcing element may engage and/or lock a flange of the profile element with the web.
  • the profile element and/or profile element main body and/or reinforcing element can be made of a (metal) sheet.
  • the profile element and/or profile element main body and/or reinforcing element can be formed by bending and/or folding and/or cutting and/or thermal conversion.
  • the abovementioned problem is solved by the use of a portion of a preliminary profile element being (at least partially) cut-out of the preliminary profile element for reinforcing a profile element main body originating from the preliminary profile element. Thereby, a reinforced profile element is achieved.
  • a profile element for supporting at least one wall partition, in particular at least one drywall plasterboard partition comprising a reinforcing element being hinged on a profile element main body so that it is rotatable from a first position to a second (reinforcing) position.
  • the reinforcing element may be connected or connectable to a profile element main body via an arresting mechanism, in particular a snap-in mechanism.
  • the reinforcing element may be a clip, e.g. made of a (shaped) metal sheet (e.g. with a U-, C-, I -, T-, CT-, L- cross section).
  • the snap-in mechanism may comprise a recess and/or a (corresponding) projection and/or edge.
  • the snap-in mechanism may comprise an edge, on the one hand, and a projection, on the other hand. Said edge and/or projection and/or recess may be part of the reinforcing element or the profile element main body.
  • the reinforcing element and the profile element main body can be made of the same material , in particular made from the same preliminary profile element by forming a cut-out within the preliminary profile element.
  • the preliminary profile element is a (metal) sheet being planar or preformed (e.g. having a U-, C-, Z-, I - or T-shape).
  • a key aspect of the present invention is in general the utilisation of an existing (service) cut-out to reinforce a profile element.
  • Another key aspect is the utilisation of an additional reinforcement clip or a plurality of additional reinforcement clips.
  • Z- profile shall mean a profile having two (substantially) parallel flanges and a bridge section ("web") linking both flanges and being arranged diagonally from one flange to the other.
  • a (regular) interval between the cut-outs may be 200 to 400 mm (in particular 300 mm) or 500 to 700 mm (in particular 600 mm).

  • Fig. 3 shows the cross-section of Fig. 2 in a second state of the profile element. The distal end 19 has been moved in the direction of an arrow 22 so that the distal end 19 comes close to a projection 23 provided on the profile element main body 21, specifically on the first flange 10.
  • a final state of the reinforced profile element is shown in Fig.4 . There, the distal end 19 has passed the projection 23 and the flange 10 has snapped back into its original position. In essence, there is provided a snap-in mechanism 25 for arresting the distal end 19 with the first flange 10 (the profile element main body).
