Definitions

  • the present invention relates to a bandraster system comprising a plurality of bandrasters and splices for connecting successive bandrasters to each other, each bandraster comprising a substantially U shaped portion with two upright side walls on opposite longitudinal sides of a base wall and an open top, each splice comprising a base and at least one upright side wall, the splice being provided to be received at least partly in an end part of the bandraster, the bandraster and splice comprising mutually co-operating connecting means w
  • the connecting means comprise mutually co-operating first and second connecting means positioned at an end part of each of the bandraster and splice, connecting means on opposite end parts pointing in opposite directions; wherein the first connecting means comprise an elongated slot, the elongated slot being positioned at a distance with respect to the bottom wall at a position shifted towards the bottom wall; wherein the second connecting means comprise a resilient longitudinal tongue provided to be received in the slot, as described in the preamble of the first
  • US-A-4492066 discloses a support grid comprising a plurality of U-shaped grid members which are connected in longitudinal direction by means of splices. Both the grid members and splices comprise a bottom and two upstanding sidewalls. Each of the upstanding sidewalls of the splice is provided with longitudinally extending projections while the upstanding sidewalls of the grid members are provided with corresponding slots. The splices can be slid into the grid members until the tongues are aligned with the slots. The tongues then snap into the slots preventing movement of the splice in a direction out of the grid member in longitudinal direction.
  • a support grid which comprises a plurality of base rails and transverse rails, each rail comprising a C shaped sheet steel section with a base and two upright side walls, which C-section is open at the top, the top edges of the side walls being inwardly angled.
  • the bottom side of the base is the visible side which gives access to the visible side of the ceiling plates suspended to the support grid.
  • the base rails are suspended to the building construction by means of suspension plates inserted into the base rails. Extension of base rails in longitudinal direction is achieved by means of U-shaped splices, which are inserted into the facing ends of two successive rails, between the side walls thereof.
  • the base rails and splices comprise mutually co-operating connecting means.
  • the splices comprise outwardly facing projections, which are provided to engage corresponding slots in the base rails. It has however been observed that the accuracy of the positioning of the slots in the splice is often insufficient and that the tolerance in height direction of the slots is too large.
  • the bases of consecutive base rails are badly aligned. This is unwanted not only from an aesthetic point of view, but also from a technical point of view, for example for fire safety reasons.
  • the bad alignment also has the consequence that mechanical stresses are generated in the support grid, which result therein that the bases of consecutive supporting rails for example extend at different heights with respect to the floor, or extend under an angle with respect to each other.
  • connection of a bandraster and a transverse rail is achieved by tongues which project from the inwardly angled edges of the side walls of the transverse rails.
  • Each tongue comprises at the end of the transverse rail a downwardly extending projection to be received in a corresponding opening in the longitudinally extending edge of a bandraster.
  • the bandraster system of this invention is characterised in that the first connecting means comprise a slit spaced apart from the elongated slot in longitudinal direction, the slit extending in height direction of the upright side wall, and in that the reception of the resilient longitudinal tongue in the slot is at such a position that an upper edge of the tongue abuts against an upper edge of the slot an end part of the tongue comprising a protruding lip which is provided to engage the slit upon engagement of a splice and a bandraster.
  • the splice is provided to be received in facing end parts of two consecutive bandrasters, in such a way that the at least one upright side wall of the splice extends along the corresponding side wall of the bandraster, and the bottom wall of the splice is received on top of the bottom wall of the bandraster.
  • the splice comprises two upright side walls
  • the upright side wall on the opposite side of the base of the splice extends along the corresponding opposite side wall of the bandraster, so that both side walls of the splice are received between the upright side walls of the bandraster.
  • the tongue is provided to engage the elongated slot in longitudinal direction
  • the lip is provided to engage the slit.
  • the tongue is provided to be received in longitudinal direction in the slot upon engagement of a splice and a bandraster.
  • the tongue is positioned such that its upper edge abuts against the upper edge of the slot, when the bottom wall of the splice rests on top of the bottom wall of the bandraster. This has the effect that a stretching force is applied between the upper edge of the slot and the bottom wall of the bandraster, or in other words a stretching force in height direction of the bandraster is applied.
  • first and second connecting means allow obtaining a bandraster system which is stretched in both longitudinal and height direction.
  • the more accurate positioning of the slot has the consequence that the risk to the building of stresses when connecting two or more consecutive bandrasters by insertion of a splice into the end parts of the consecutive bandrasters may now be reduced.
  • the positioning of the elongated slot shifted towards the base of the bandraster has the effect that clamping forces clamping the splice into the bandraster act in the vicinity of the bottom wall of the bandraster.
  • the moment of the forces acting upon the bandraster and splice gets minimised, which in turn has the effect of minimising the risk to deformation of the bandraster.
  • a bandraster system may be obtained in which an improved alignment of successive bandrasters may be obtained and an improved stretching of the bandrasters in all directions. This is attributed to the combined action of
  • first connecting means are provided on opposite ends of the upright side walls of the bandraster, while the second connecting means are provided on opposite ends of the at least one upright side wall of the splice.
  • the tongue of the second connecting means protrudes from the splice towards the bandraster, and that similarly the lip protrudes from the tongue towards the bandraster.
  • the tongue When connecting a bandraster and splice, the tongue is sled along the slot, until the lip is received in the slit. Receiving of the lip in the slot involves that the tongue engages the slot. If so desired, the tongue may be manually pushed into the slot, the resiliency of the tongue providing for the removable connection.
  • the splice is essentially U-shaped with an open top and two parallel upright side walls extending along opposite longitudinal sides of the longitudinal bottom wall.
  • the upright side walls are provided to exert an outwardly directed force to the upright side walls of the bandraster, as a consequence of which a stretching force is exerted in width direction of the bandraster.
  • the top edges of the opposite side walls may be bent inwardly towards the inner space in view of further fixing the position of the splice within the bandraster and thus adding to the fixation of consecutive bandrasters with respect to each other.
  • a preferred embodiment of the invention is characterised in that the bandraster system of this invention comprises at least one bandraster and splice having a bottom wall with a groove protruding towards the inner space of the bandraster and splice.
  • the groove of the splice is provided to receive the groove of the bandraster, the dimensions of both grooves being adapted so as to provide a close fit. In this groove for example the top edge of a partition can be received, so that the bandraster system and the ceiling supported by the bandraster system continue over the partitions, which enhances the aesthetic appearance.
  • the bottom wall of the splice comprises at least one resilient tongue which protrudes from a face of the bottom wall of the splice pointing away from the inner space, towards the bottom wall of the bandraster.
  • the presence of such resilient tongue allows to compensate for any tolerance occurring in height direction of the bandraster and splice in view of obtaining an optimum alignment of the base walls of successive bandrasters, to fix the position of the splice within the bandraster and to improve the stretching of the bandraster in height direction.
  • the thus produced additional stretching in height direction has the effect that an optimum alignment of consecutive bandrasters may be achieved, as the position of consecutive bandrasters is now controlled in longitudinal direction, width direction and height direction of the bandraster and splice.
  • a ceiling extending at different levels may be built with a bandraster system which comprises at least one bandraster and splice the longitudinal bottom wall of which comprises a first and second longitudinally extending part, which slant with respect to each other along a longitudinally extending fold between them.
  • the first and second part may slant towards or from each other, depending on the direction in which the ceiling is to slant.
  • the bandraster system of this invention is also characterised in that it comprises at least one bandraster having a longitudinally extending flange which protrudes with respect to and extends along the upright side wall of the bandraster.
  • the flange comprises a bottom face which extends in line with or in other words at the position of the bottom face or base wall of the bandraster.
  • This flange in fact forms a support surface for the ceiling panels received between consecutive bandrasters, the edges of the ceiling panels supported by the flange being hidden above the flange.
  • the fact that the bottom face of the bandraster is continued into the flange improves the aesthetic appearance.
  • the bandraster system of this invention preferably comprises at least one transverse splice.
  • the transverse splice in fact functions as a connecting piece connecting bandrasters which extend in perpendicular directions.
  • the transverse splice of this invention comprises at an end part thereof suspension means for suspending it to the side wall of a bandraster which extends transversally with respect to the splice.
  • the transverse splice further comprises second connecting means as described above, for connecting it to a bandraster extending longitudinally with respect to the transverse splice.

  • the connecting means preferably comprise a top hook portion with clamping means to be clamped over the top edge of the upright side wall of the transversally extending bandraster.
  • transverse splice characterised by the presence of at least one resilient tongue which protrudes from a bottom face of the transverse splice in the direction of the longitudinally extending bandraster.
