Abstract
The invention relates to a suspended ceiling structure consisting of hangers (54) to which supporting yokes (30) are attached. To the sides of the supporting yokes there are screwed leaf springs (33, 34) and side plates (35, 36) for the channels of the suspended ceiling. The upper ends of the side plates are bent inwardly (35a, 36a) for suspension from the side flanges of the supporting yoke. The lower ends of the side plates are bent outwardly to form a Z-section (35b, 36b) for supporting tiles (13) etc. The supporting yoke has punched out and bent-up fasteners (46-49) for attaching and fixing cable channels (32) in position. A cover (37) is formed as a channel consisting of an underside and two bent-up side flanges, said side flanges being compression-moulded to form longitudinal semicircular arches (60, 61) intended to be snapped against the leaf springs to secure the cover to the other parts of the suspended ceiling.
Description
- The invention relates to a suspended ceiling structure according to the precharacterising part of
Claim 1. - In the case of new construction, renovation and reconstruction of office buildings, storehouses, industrial buildings and workshops, etc., a suspended ceiling plays an important role as a platform for modern installation technique. The suspended ceiling is to accommodate cables for electricity supply, lighting, loudspeakers, telephones, data installations, etc., as well as devices for ventilation, sprinklers, and so on. In addition, the suspended ceiling structure is to be capable of supporting light fittings of different kinds, sound absorbing plates, and baffles, etc. In other respects, the suspended ceiling is to be of flexible construction, be easily accessible, and have an aesthetically attractive shape.
- In order to become familiar with the specific problems the present invention deals with a prior art embodiment of a suspended ceiling will first be described with reference to the Figures 1 to 3. The previous design, selected for this purpose, is produced by one of the major suppliers of suspended ceilings in the Nordic countries, namely JÄRNKOST AB, the design being described, inter alia, in JÄRNKONST AB'S pamphlet BSAB G 8.6, June -85.
- Figure 1 shows a portion of the afore-mentioned suspended ceiling. It is built up in the form of a modular system consisting of a number of
primary channels secondary channels 3 and 4 extending perpendicularly to the primary channels. These channels are often commonly designated "cable channels" or "power supply channels". The channels are suspended from the ceiling by means of supportingyokes adjustable hangers 9, 10, 11 and 12. The suspended ceiling surface between the channels is formed in different ways depending on the type of premises, the desired lighting, sound damping, etc. In the example shown in Figure 1, acoustically damping plates ortiles 13 are suspended from so-called T-sections arranged on Z-sections 20 which are attached to the primary or secondary channels. Figure 1 also shows how alight fitting arm 15 supports alight fitting 16 and associated means forlighting control 17. The channels may be formed in a plurality of different ways depending on the cable arrangement and installation in question. - Figure 2 shows a section through a primary or cable channel along the line A-A in Figure 1. As will be clear from the Figures 1 and 2, it is possible to lay the cables in separate spaces in this channel provided by an inner U-V-
shaped channel 18. As will also be clear from both figures, both the primary and the secondary channels 1-4 are provided with external Z-sections - Figure 3 shows a section taken along line B-B in Figure 1, i.e. at the hanger 9. This figure also shows how the
primary channel 1, via thebent edges secondary channels 3 are screwed through theprimary channel 1 and the supporting yoke. - As is clear from Figure 1, the supporting yokes, which are used when the secondary channels are to be connected to the primary channels, having sides with punched out
openings cable 24 between thelighting control 17 and the light fitting 16. - The prior art also comprises supporting yokes with no punched openings, which will be used in suspended ceilings in which, for various reasons, no secondary channels are included.
- As will also be clear from Figures 2 and 3, space-separating
partition walls 26 are mounted directly against the underside of the cable channels. To fix thepartitions 26 against the suspended ceiling, holes for screws etc. are provided in the underside of the channels. In view of the turbulence that characterizes management organization and in order to adapt to a changed production demands etc., it occurs relatively frequently that space separating partitions have to be moved. Because the flexible and modular construction of the suspended ceilings, premises can be easily relocated in view of the location of the partitions, lighting, telephones, etc. However, the holes which have been provided in the underside of the channels for fixing partitions will remain when moving the partitions and will constitute a disturbing feature in the aesthetic appearance. To avoid this with exisiting constructions the respective primary and/or secondary channels have to be replaced by new channels. Such a replacement is a relatively complex measure since it influences the actual laying of cables as well as the primary and secondary channels and the rest of the ceilings structure, such as acoustic tiles, light fittings, etc. - Figure 4 which is identical with Figure 2 in the SE-B-7214120-3 with publication number 383 410 demonstrates the use of snap-on connecting elements 27 and 28 for suspended celings to fix sound-damping or absorbing
tiles 29 in position. However, as will also be clear from the construction, it must be practically impossible to separate the connecting elements, once they have hooked onto each other, without destroying them. - In order to overcome the afore-mentioned shortcomings of the prior designs, the invention aims at developing a suspended ceiling structure of the above-mentioned kind which permits replacement of such channel parts, in which it has been necessary to make holes for attachment of partitions, without having to replace the entire cable channel.
- To achieve this aim the invention suggests a suspended ceiling structure according to the introductory part of
Claim 1, which is characterized by the features of the characterizing part ofClaim 1. - Further developments of the invention are characterized by the features of the additional claims.
- A suspended ceiling structure according to the invention enables the relocation of partitions without having to replace entire cable channel to remove the unsightly drill holes of prior partition wall attachments.
- A suspended ceiling structure affording to the invention, seen from below, has the same appearance as the structure already described. On the other hand, the channels and the associated parts are formed in quite a new way, which per mits a considerably simpler procedure during installation and service and when moving partitions.
- The new structure includes newly formed supporting yokes, cable channels of a simpler design, channel side plates with a new profile comprising the above-mentioned Z-section for supporting tiles etc., a number of snap-on leaf springs and a cover formed as a channel, the sides of which are formed in a special way.
- The newly designed supporting yokes are screwed, as in existing suspended ceiling structures, to a hanger. The supporting yokes are provided with punched out, bent-up clamp fasteners, under which cable channels of different designs, depending on how the cables in question are laid, can be inserted and fixed. Further, the supporting yokes are provided with punched-out holes, through which the bendable leaf springs extend, which are screwed to the side flanges of the supporting yokes, to both side flanges of the supporting yoke, the side plates of the channels are fixed with the same screws as the leaf springs. At their lower end these plates are formed with an outwardly-turned Z-section for supporting tiles, baffles, etc. The cover is formed as a channel consiting of an underside and bent-up side flanges which are compression-moulded to form horizontally extending, semicircular arches adapted to engage with the snap-on leaf-springs and adapted to the remaining part of the suspended ceiling.
- By means of the additional Figures 5 to 8 the suspended ceiling structure according to the invention will now be described in detail, but at first a compiled survey over the total number of Figures will be given:
- Figure 1 shows a perspective view of a suspended ceiling structure according to the prior art,
- Figure 2 shows a sectional view of a channel of the construction along line A-A in Figure 1,
- Figure 3 shows a sectional view of a crossing between two channels along line B-B in Figure 1,
- Figure 4 shows a snap-on design solution for the suspended ceiling in Figure 1,
- Figure 5 shows parts included in a suspended ceiling structure according to the invention,
- Figure 6 shows section through an assembled suspended ceiling structure according to the invention and
- Figure 7 shows an alternative embodiment of a suspended ceiling structure according to the invention.
- The various components which together constitute the new suspended ceiling structure are clear from Figure 5. Two embodiments of the new supporting yokes are shown at 30 and 31, the
yoke 30 being used in connection with a ceiling suspension when only one primary channel is to be installed, and theyoke 31 being used when both primary and secondary channels are to be installed. Further, there are shown acable channel 32,leaf springs side plates cover 37. - In both the supporting yokes there is a rectangular centre hole, indicated at 38 in supporting
yoke 31, for the attachment of a hanger. - The supporting
yoke 30 consists of arectangular bottom plate 39 with twoside flanges bottom plate 39 has four punched,rectangular holes clamp fasteners side flanges holes holes - Via the holes 50-53,
leaf springs side flanges yoke 30 in such a way as to be enable the leaf springs to being elastically movable in therectangular holes side plates yoke 30. The upper edge of the side plates has an inwardly-bent edge side edges yoke 30, and the lower end of the side plates has an outwardly extending Z-bent section 35b and 36b, respectively, for supporting tiles, etc. - The
cable channel 32, or any other channel, is inserted and fixed under the bent-up clamp fasteners 46-49 on the bottom of the supportingyoke 30. - The
cover 37 is formed as a channel with a plane underside and with bent-up side flanges which, as will be clear from Figure 5, are compression-moulded so as to attain asemicicular section cover 37 form a snap-on mechanism enabling thecover 37 to be applied and removed, respectively, in a very simple manner. - The space in the cover channel, i.e. the space between the
cover 37 and the underside of the supporting yoke and the cable channel, respectively, may suitably be filled with sound and fire insulating mineral wool. To achieve a suspended ceiling with improved sound absorbing properties, the plane underside of thecover 37 may be perforated in accor dance with different configurations, for example in some form of triangular perforation. - Figure 6 shows a section of a suspended ceiling, as the one described above, with a supporting
yoke 30 suspended from ahanger 54, with acable channel 32, withleaf springs side plates cover 37 which is snapped on with the aid of these parts. On the lower Z-shaped part of theside plates tiles 13 of various kinds are resting. - The supporting
yoke 31, which will be used in connection with a channel bifurcation between the primary and the secondary channel, is clear from Figure 5. Thisyoke 31 consists of acruciform bottom plate 55 with angled and turned-upside flanges hole 38 for a hanger, thebottom plate 55 is provided with openings for the leaf spring and bent-up clamp fasteners for fixing the cable channels. The side plates for the respective channels are mounted in the same way as when mounting against supportingyoke 30, i.e. against the angled side flanges using the same screws as are used for fixing the leaf springs. - Figure 7 shows an alternative embodiment of the invention in which a supporting
yoke 30, turned upside down, is used. Thebottom plate 39 of theyoke 30 will then be positioned nearest the ceiling and the bent-upclamp fasteners yoke 30 are now facing downwards. To guide thesprings side flanges holes - Otherwise, it is clear from Figure 7 that the cable channel 32 (see Figures 5 and 6) has been replaced by
U-shaped channels cable channels 68 which are installed above the primary and secondary channels are somewhat narrower than thecable channels 67 mounted inside the primary or secondary channel. Thecable channels 68 have punched openings on the bottom so as to fit over and be clamped by the bent-upfasteners side plates openings 62 for suspending theinner cable channels 67, which are formed with corresponding bent-out clamp orsuspension fasteners
