Definitions

  • the present disclosure generally refers to support structures, or load-bearing structures, of false ceilings, i.e. support structures for walls or panels, which are placed underneath a regular ceiling.
  • Such support structures generally comprise a first element, which is adapted to be fixed to the ceiling rising above the false ceiling, wherein such first element is a so-called hanger, a steel rod, a threaded rod or a metal profile.
  • a second element of the support structure is, e.g., a metal profile, preferably but not exclusively C- or U-shaped, which lies under the first element, and on which the false ceiling is mounted.
  • a connection article is provided which connects the first element with the second element of the support structure for false ceilings.
  • connection article a support structure of false ceilings comprising a combination of the connection article and the metal profile, and a method of fixing the connection article to the metal profile.
  • a known connection article comprises a properly shaped sheet metal intended, on one side, for connection with the hanger and comprising, in a zone opposite to the connection zone with the hanger, a coupling portion intended to be fixed to a metal profile.
  • the sheet metal comprises one or more notches obtained on opposite side edges of the sheet metal.
  • the sheet metal is inserted in a cavity of the metal profile defined by opposite side walls or shoulders of the C- or U-shaped profile, and the notches are intended to receive respective edges of the lateral sides of the metal profile.
  • the sheet metal is inserted inside the cavity present in the metal profile, and then the sheet metal is rotated, of an adequate angle, until making a joint-type coupling between the notches in the sheet metal and the corresponding edge or projection of the metal profile.
  • connection article entails some drawbacks which are yet to be overcome.
  • a drawback lies, e.g., in the fact that it has been found that such a connection article does not always guarantee a constant connection with the metal profile.
  • connection article for a support structure for a false ceiling allowing to overcome the drawbacks mentioned above with reference to the known art, and/or to achieve further advantages and/or to have further features.
  • connection article according to independent claim 1 and a method of fixing according to claim 16.
  • Specific embodiments of the subject-matter of the present disclosure are set forth in the corresponding dependent claims.
  • connection article when installed on-site, is arranged with a substantially vertical orientation and lies inserted substantially vertical into the metal profile, so as to receive the edges of the metal profile into the respective notches.
  • any spatial reference such as, e.g., “above”, “top”, “below”, “bottom”, “horizontal”, “vertical”, “forward”, “behind”, is to be understood in a non-limitative way and merely by way of example, with reference to the above-mentioned substantially vertical orientation of the connection article when it is installed on-site.
  • connection article includes a sheet metal body bent to a C or U shape, and four notches obtained on side edges of said sheet metal body.
  • the four notches are located in the region of as many (four) angle zones or vertex zones of a quadrilateral arranged substantially horizontal.
  • the connection article further comprises retaining means, each of which is associated to a respective notch of said four notches.
  • the retaining means is arranged so as to exert retaining on the edges of the metal profile, which retaining, following a perimeter of the quadrilateral, occurs alternately from above and from below a horizontal ideal plane passing through said notches.
  • Such ideal quadrilateral is e.g., a rectangle.
  • first retaining means lies in a top zone of the respective first notch
  • second retaining means lies in a bottom zone of the respective second notch
  • third retaining means lies in a top zone of the respective third notch
  • fourth retaining means lies in a bottom zone of the fourth notch.
  • the retaining means thus arranged alternately above and below the notches, that is at the zones receiving the edges of the metal profile, allow to contain, alternately above and below along said perimeter, the edges of the two lateral sides of the metal profile, when the latter is received into the respective notch.
  • the alternate arrangement causes, once associated the connection article to a respective metal profile, the following coupling to occur.
  • Two successive notches of the quadrilateral are connected and associated to a first side of the metal profile, and the other two successive notches of the quadrilateral (e.g., the second notch and the third notch) are connected and associated to the other side of the metal profile.
  • Each side of the metal profile is therefore contained from above and from below by the respective retaining means.
  • the coupling article may be subjected to accidental release from the metal profile, e.g. as a result of vibrations, noises, earthquake shocks or settlings of the building, various stresses, wrong couplings or manufacturing tolerances, as well as of any assembly not done in a workmanlike manner, i.e. as a result of an incomplete or incorrect assembly.
  • the presence of retaining means alternately arranged from opposite sides, above and below an ideal plane passing for the notches, allows to obtain four points of coupling to the respective metal profile, which work in an alternate sequence, and therefore a firm joint.
  • the retaining means are defined by the shape or outline of the notches. That is, the notches are configured and shaped so as to stably contain and hold the edges of the metal profile that are received into the notches.
  • the first notch includes a recess, e.g. saddle-shaped, said recess being part of said first retaining means, and being arranged for instance above the above-mentioned plane, so as to act from above or rise above an edge of the metal profile that is received into the recess.
  • the second notch has the shape of an oblique louver, defining an oblique portion of the sheet metal body underlying the respective notch, said oblique portion being part of said second retaining means.
  • the third notch includes a recess, e.g. saddle-shaped, said recess being part of said third retaining means, and being located, e.g., above the above-mentioned plane, so as to act from above or rise above an edge of the metal profile that is received into the recess.
  • the fourth notch has the shape of an oblique louver, defining an oblique portion of the sheet metal body underlying the respective notch, said oblique portion being part of said fourth retaining means.
  • the first notch receives the edge of the profile into the respective saddle or recess
  • the oblique portion underlying the second notch pushes from below, or exerts a pressing contact against, the edge of the profile
  • the third notch receives into the saddle or recess the edge of the profile
  • the oblique portion underlying the fourth notch pushes from below, or exerts a pressing contact against, the edge of the profile.
  • the two lateral sides of the metal profile are stressed in a diametrically opposite way, i.e., with respect to the length of the metal profile, one side is stressed, e.g., from below in a front zone and from above in a rear zone, whereas the other side is stressed from below in a rear zone and from above in a front zone.
  • This configuration causes the first retaining means and the third retaining means, being placed in diagonally opposite zones of the above-mentioned quadrilateral, to push and exert a retaining action from above an edge of a side of the metal profile and an edge of the other side (opposite side) of the metal profile, whereas the second retaining means and the fourth retaining means, being placed in diagonally opposite zones of the above-mentioned quadrilateral, push and exert a retaining action from below an edge of a side of the metal profile and an edge of the other side (opposite side) of the metal profile.
  • the metal profile is induced also to a slight bending along the diagonal (therefore a slight torsion) at the moment of coupling, and to a further elastic return into a coupled condition, fostering the locking.
  • the first retaining means and the fourth retaining means respectively comprise a fin lying beside the respective recess of the first notch, and a fin lying beside the respective recess of the third notch.
  • the fins serve as a further side retaining element for the metal edge, and prevent a rotation return of the metal profile when the latter is received into the four notches.
  • connection article for a support or load-bearing structure for false ceilings is denoted by reference number 1.
  • a support structure for supporting a false ceiling is denoted by number 10.
  • connection article 1 is intended to connect, by a spring coupler 2, a first element of the support structure 10, such as a hanger, a steel rod, an iron wire, a nonius-type coupling, a threaded rod or alike element (not illustrated in the drawings), and a second element, such as in the example a metal profile 4, also known as C profile or U profile.

  • the radiate shape of the fin 352 and of the fin 382 acts as a pilot section for the edge 42 during the motion of rotation, in order to drive the edge 42 into the recesses 35a, 38a.
  • each lateral side 45 of the metal profile 4 causes each lateral side 45 of the metal profile 4 to be contained from above, e.g. by the recess 35a which is part of the first retaining means and lies behind in the longitudinal direction Z, and from below, e.g. by the oblique portion 372, which is part of the fourth retaining means and lies ahead in the longitudinal direction Z.
  • the other lateral side 45 of the metal profile 4 is contained from below, e.g. by the oblique portion 362 which lies behind in the longitudinal direction Z and is part of the second retaining means, and from above by the recess 38a, which is part of the third retaining means and lies ahead in the longitudinal direction Z.
  • This coupling allows to obtain a slight bending in the longitudinal sense and diagonally (therefore a slight torsion) of the metal profile 4; hence, a spring effect or an elastic return effect of the metal profile 4 in the two coupling zones, in a coupling condition can be obtained.
  • connection article for a false ceiling can contribute to prevent a rotation, and therefore an undesired release of the article, thanks to the presence of retaining means to form four coupling points.
  • Such a configuration of the article for a false ceiling can enable to avoid that knocks or vibrations or plays due to the weight of the false ceiling cause an undesired rotation of the article for a false ceiling, with the entailed accidental release of the metal profile.
  • the article for a false ceiling according to the present disclosure can obviate to another problem based on the grades and the construction tolerances of article for a false ceiling and metal profile.
  • support structures for false ceilings are formed by sheet metal elements, or lattens which are light carpentry elements; there is the risk that such components, though being manufactured in a workmanlike manner, could exhibit edges or notches with tolerances or punctual defects linked to the production process or to the transport.
  • This condition might entail each coupling having slightly different plays or interferences, and therefore plays being created between article for a false ceiling and metal profile, or wrong assembling, with consequent noises and vibrations and therefore lack of comfort.
  • connection article 1 is allowed along the length of the metal profile, by application of a light pressure on the connection article 1 by an operator.
