Description

SPECIFICATION Supporting arrangements for suspended ceilings This invention relates to supporting arrangements for suspending ceilings composed of a series of side-by-side rows of tiles formed for example of gypsum.
Such supporting arrangements normally comprise primary support members in the form of a plurality of sheet metal channel members extending parallel to each other and suspended from the fabric of the building by hanger rods and a plurality of sheet metal tile-locating longitudinals extending transversely of the channel members and parallel to each other and secured to the channel members. Each adjacent pair of longitudinals supports one row of tiles and each longitudinal supports the adjacent edges of two adjacent rows of tiles. For this purpose each of the longitudinals is provided along its length with oppositely extending lateral flanges which provide ledges on which side edges of the tiles rest.
The channel members are arranged on their side so that the sides of the channel member extend horizontally one above the other. The hanger rods are then secured to the upper sides of the channel members and the longitudinals are secured to the lower sides of the channel members. To assemble the channel members and longitudinals togetherthe longitudinals are provided with a horizontal web along their upper edge, and the practice in the past has been to locate the longitudinals in position and then make a drilling through the horizontal web and the adjacent side of the channel member and the bolt them together through the drilling. This a very time-consuming and therefore expensive assembly method and does not allow for any adjustment with the longitudinals temporarily attached to the channel members.
An object of the present invention in one of its aspects is to provide an assembly arrangement which provides a preliminary securement of longitudinals to the primary support members allowing adjustment of the longitudinals prior to final secured ment.
According to said one aspect of the invention a longitudinal is assembled to a primary support member by a saddle bracket which locates over the top of the channel member and has side limbs which extend below the lower side of the channel member, the side limbs having slits extending into them from one edge at the level of the lower side of the primary support member, in which slits is located the web of the longitudinal, and a clamping screw is provided in the top of the saddle bracket and which when tightened up against the top of the primary support member causes the web of the longitudinal to be clamped tightly against the lower side of the primary support member.
Thus with the clamping screw slackened off the saddle bracket can be slid along the primary support memberto adjust the position ofthe longitudinal.
Preferably the slits in the side limbs of the saddle bracket are widened at their inner closed ends to locate a bead extending along the free edge of the web so that the web becomes trapped in the slits.
The bead may be snap fitted into the slits. One way of achieving this is to arrange the upper edges of the slits in the saddle bracket to lie just above the lower surface of the lower side of the primary support member, the spacing between said lower surface and the lower edges of the slits over their narrower parts being less than the bead thickness. The bead on the web has then to be forced along the narrower part of the slits against the lower side of the primary support member until its snaps into the wider part of the slits. The inherent resilience of the interfitting parts permits this snap-fitting.
In supporting arrangements for suspending ceilings, each longitudinal may be made up from plurality of sections arranged end to end. An object of a second aspect of the invention is to provide a simple jointing arrangement between two longitu dinal sections.
According to said second aspect of the invention in a jointing arrangement for a pair of longitudinal sections, an elongated jointing member interfits with the adjacent end portions of the longitudinal sec tions to interconnectthem, the jointing member being trapped at its longitudinal edges within the cross-sectional profile of the longitudinal sections and being held under stress created by the tight interfitting of the jointing member and the longitudinal sections.
The invention will now be further described by way of example with reference to the accompanying drawings, in which: Figure 1 shows a perspective view, partly in section of one supporting arrangement in accordance with the invention, Figure 2 is a side view, partly in section through the supporting arrangement, Figure 3 illustrates a modification of the one of the components of the supporting arrangement of Figures 1 and 2, and Figure 4 and 5 illustrate different stages in the fitting of a jointing member for connecting together two end to end sections of a longitudinal used in the supporting arrangement of Figures 1 and 2.
Referring now to Figures 1 and 2, the supporting arrangement comprises a series of parallel channel members 1 arranged on their side, so that the sides 2 and 3 of the channel member 1 are located one above the other. The channel members are suspended from the fabric of the building in which the suspended ceiling is to be fitted by hanger rods (not shown) which are secured at their lower ends to the upper sides 2 of the channel members 1. Tile supporting longitudinals 4 extend parallel to each other and at right angles to the channel members 1 and are secured to the channel members 1 by saddle brackets 5.All the items 1, 4 and 5 are formed from sheet metal by pressing. Between each pair of adjacent longitudinals 4 is located a row of tiles and each longitudinal supports the adjacent edges of the tiles in adjacent rows. In Figures 1 tiles 6 and 7 of adjacent rows are shown.
Along its lower edge each longitudinal 4 is provided with oppositely directed flanges 8 and 9 which provide tile supporting ledges. The opposite tile edges supported on the flanges 8 and 9 are profiled so that the edges of the tiles in adjacent rows interfit as shown in Figure 1 and conceal the flanges 8 and 9.
The longitudinals 4 have a generally vertical web 11 extending upwardly from the flanges 8 and 9 and a web 12 which extends horizontally from the top of the vertical web 11. In known manner the web 11 is bent to provide space 13, into which, as seen in the drawings, the right hand edge of any tile can be displaced after it has been pivoted upwardly about its left hand edge, to permit its left hand edge to be released from the ledge 9 of the longitudinal supporting it, so that the tile can be dropped through the space between the pair of longitudinals to remove it from the ceiling without dismantling the supporting arrangement.
The saddle bracket5 has side limbs 14 and 15 which extend below the lower side 3 of the channel member 1. At the level of the side 3 the limbs 14 and 15 are provided with horizontal slits 16 extending into them from one edge. These slits 16 receive the horizontal web 12 of the longitudinal 4 to locate it in position. The inner ends of the slits 16 are widened at 17 as shown to locate a bead 18 extending along the free edge of the web 12 and formed by bending over the sheet metal of the longitudinal 4. Thus the web 12 is trapped in the slits 16. The top 18 of the saddle bracket 5 is provided a captive nut 19 in which engages a bolt 20. Tightening of the bolt 20 causes it to press against the upper side 2 of the channel member 1 to draw the saddle bracket 5 upwardly and so clamp the web 12 against the side 3 of the channel member 1 to secure the longitudinal 4 in position.Prior to this tightening of the bolt 20 the saddle bracket can be slid along the channel member 1 to adjust the position of the longitudinal 4.
As best seen in Figure 2 the upper edges of the slits 16 lie just above the lower surface of the lower side 3 of the channel member 1 when the bolt 20 is about fully retracted into the nut 19. It is designed that the gap thus provided between the lower surface of the side 3 of the channel member 1 and the lower edge of the slits 16 over their narrower part is slightly less than the thickness of the bead 18 on the horizontal web 12. To fit the web 12 it has therefore to be forced along this gap, the inherent resilience of the sheet metal components permitting this, until the bead 18 snaps into the wider part 17 of the slits 16.
Figure 3 shows a modification of the saddle bracket 5 in which the captive nut is replaced by a downwardly punched hole 21 and the bolt is replaced by a self-tapping screw 22. The hole is punched downwardly ratherthan upwardly, so that any tendency of the screw 22 to puil out of the hole will cause the punched metal forming the hole to pull tightly on to the screw 22.
Referring to Figures 4 and 5, these illustrate how two longitudinal sections which are arranged end to end and abutting can be jointed together. To effect this a jointing member 24 member is used which fits into the cross-sectional profile of the longitudinals and extends across the abutting ends of the two longitudinal sections. For convenience only one longitudinal section referenced 4a is shown in the drawings.
As can be seen in the drawings, the flanges 8 and 9 of the longitudinal are formed integral with the vertical web 11 by bending the sheet metal, the free edge of the sheet metal terminating in the flange 8 at a short distance from the vertical web 11, to leave a shallow groove extending along the longitudinal 4 adjacent the vertical web 11. The cross-sectional profile of the jointing member 22 conforms to the vertical and horizontal webs 11 and 12 of the longitudinal and thus has vertical and horizontal webs 23 and 24. The lower edge of the vertical web 23 is turned slightly so that it fits readily into the aforesaid groove and the width of the horizontal web 24 is less than that of the horizontal web 12 of the longitudinal sections so that its free edge becomes trapped behind the beads 18 of the longitudinal sections. The profiling of the jointing member 2 is slightly different from that of the longitudinal sections so that there is a stressed interfitting between them, permitted by the inherent resilience of the longitudinal sections and the jointing member 22.
Thus with the lower edge of the jointing member trapped in the groove the free edge of the horizontal web 24 is urged into engagement with the bead 18, to hold the jointing member firmly in the crosssectional profile of the longitudinal sections.
As illustrated in Figure 4, the jointing member 22 can be readily snap-fitted into each of the longitudinal sections by first fitting its lower edge into the groove and then rotating the jointing member until its free edge snaps behind the bead 18. During this rotation the horizontal web 12 is deflected upwardly and stressed, this being permitted by the inherent resilience of the longitudinal.
