Definitions

  • the present invention relates to a bandraster system for constructing a suspended ceiling, according to the preamble of the first claim.
  • the present invention also relates to a connection member therefor and a method for installing a suspended ceiling using the bandraster system.
  • bandraster systems for construction suspended ceilings are known to the person skilled in the art.
  • EP A1 1561875 and DE A1 2109596 both describe a bandraster system for construction a suspended ceiling comprising a U-shaped longitudinal bandraster member comprising a longitudinal base with respectively a first and a second longitudinally extending upright side wall along opposing longitudinal first and second edges of the base.
  • the first and the second side wall respectively comprise a first and a second flange respectively extending inwardly from a first and a second top edge of the first and the second side wall.
  • the base, the side walls and the flanges delimit a connection volume.
  • the bandraster systems further comprise a connection member for connecting the U-shaped bandraster member into the remainder of the suspended ceiling.
  • connection member comprises a connection part for connecting the bandraster member to the connection member.
  • the connection part is provided to be snap-fittingly received in the connection volume for releasably mounting the connection member to the bandraster member.
  • the connection part comprises a first and second part respectively provided to be received between the first flange and the base and the second flange and the base.
  • the bandraster system described by EP A1 1561875 for example comprises a connection member with a connection part that is provided to be slid into position along longitudinal direction of the bandraster member such that the first and second part are respectively provided to be received between the first flange and the base and the second flange and the base.
  • connection member which can be snap-fitted into the connection volume.
  • the first part comprises an upright protrusion provided to be received between the first upright side wall and the first flange.
  • Such a connection member however must be snap-fitted into the volume by pressing the connection member into the volume with a force which is substantially perpendicular to the longitudinal direction of the base of the bandraster member since the space around the protrusion of the first part is too limited to allow any other method of snap-fitting the connection member into the volume.
  • Such a way of mounting the connection member into the volume however often requires that the bandraster member needs to be put on the floor with the volume facing upwardly after which the connection member is pushed into place. It is difficult to mount the bandraster member to the connection member when the connection members are, for example, already suspending from a ceiling to create a suspended ceiling.
  • the protrusion, the connection member and the bandraster member are provided such that the bandraster member can be connected by the connection member by hooking the bandraster member on the connection part of the connection member by putting the protrusion between the first side wall and the first flange after which the connection part is snap-fittingly received in the connection volume by rotating the second part and the bandraster member with respect to each other around the protrusion into the connection volume such that it is received between the base and the second flange.
  • connection member allows to mount the bandraster member to the connection member without having to exert a perpendicular force to the base but instead allows to rotate the second part and the bandraster member with respect to each other around the protrusion into the connection volume such that it is received between the base and the second flange after hooking the bandraster member on the connection part of the connection member by putting the protrusion between the first side wall and the first flange.
  • the second part comprises a second upright protrusion provided to be received between the second upright side wall and the second flange when the second part is provided between the second flange and the base.
  • a second protrusion improves the mounting of the connection part into the volume of the bandraster element and decreases the risk that the connection part unwontedly leaves the volume.
  • the second part is at least partly delimited by an upright edge for guiding the second wide wall during rotation of the second part, the upright edge extending outwardly from the base of the bandraster member to the second side wall when the connection member is mounted to the bandraster member.
  • an upwardly extending edge allows a more easy mounting of the connection member to the bandraster member as prior to establishing the snap-fit connection of the connection part in the volume of the bandraster member, during rotation of the connection member, the second side wall is pushed outwardly with respect to the volume creating the necessary space for allowing the connection part to enter the volume.
  • the connection member comprises a suspension part for attaching the connection member to a ceiling.
  • a suspension part allows the connection member to be used for suspending the bandraster member to a ceiling and therefore to create a suspended ceiling.
  • Such a connection member allows to more easily connect a bandraster member into a suspended ceiling as the bandraster member can be hooked on the connection members and can suspend from the connection member before establishment of the snap-fit connection of the connection part into the volume. Therefore, the bandraster member can be intermediately suspended before having to mount the connection member to the bandraster member and the bandraster member and the connection member, for example, no longer need to be premounted before attaching the connection member to the ceiling.
  • connection member comprises a second connection part for connecting a second bandraster member to the connection member.
  • a second connection part allows to connect a second bandraster member to the connection member, for example to longitudinally interconnect two bandraster members when the first and the second connection part of the connection member longitudinally extend away from each other.
  • the connection part comprises a paramagnetic flange running substantially parallel with the base of the bandraster member when the connection member has been mounted to the bandraster member.
  • a flange allows to mount a magnetic element to the connection part.
  • a mark for indicating the position correct position of the bandraster member and/or connection member and/or the suspended ceiling which is created can be magnetically mounted to the connection member during mounting such that the position, more in particular the height, of the connection member can be adapted to the required position.
  • the second part comprises a foldable securing flange extending out of the volume, when the connection part is snap-fittingly received in the volume, and provided to be at least partly folded around the second flange.
  • the invention also relates to such a connection member.
  • the invention also relates to a method for constructing a suspended ceiling using a bandraster system according to the invention in which the following steps are performed:
  • Such a method allows a more easy creation of a suspended ceiling as it allows to intermediately suspend a bandraster member to the at least one connection member or at least two connection members or to interconnect two bandraster members to each other with the at least one connection member. It becomes for example possible that a single person is able to mount the suspended ceiling in which case firstly the connection members are suspended after which the bandraster members are hooked on it and after which the bandraster members are snap-fitted into the volume.
  • Figure 1 shows an embodiment of the connection member 1 according to the current invention.
  • the connection member 1 is adapted to connect a U-shaped bandraster member 2 into the remainder of the suspended ceiling.

  • the first 7 and the second 8 side wall respectively comprise first 11 and second 12 flanges respectively extending inwardly from a first 13 and a second 14 top edge of the first and the second 8 side wall.
  • Such U-shaped bandraster members 2 are usually made of metal such as for example steel, more in particular stainless steel or galvanized steel, and are often folded from a single metal plate.
  • connection volume is for example shown in figures 2 , 3a, 3b and 3c and is in this case rectangular.
  • shape of the volume however can be adapted to the specific application of the bandraster system.
  • connection member 1 comprises a connection part 3 for connecting the bandraster member 2 to the connection member 1 and provided to be snap-fittingly received in the connection volume for releasably mounting the connection member 1 to the bandraster member 2.

  • the second protrusion 16 is provided to be received between the further flange 27, the second flange 12 and the second side wall 8.
  • Such a second protrusion 16 allows the connection part 3 to be more securely snap-fitted into the volume allow a more secure mount of the connection member 1 to the bandraster member 2.
  • the first protrusion 15 provided on the first part 4 is preferably also provided to be received between the further flange 27, the first flange 11 and the first side wall 7.
