Definitions

  • a ceiling construction with air-cooled lighting fixtures and arranged for air supply and/or removal to/from the underlying room according to the invention is comprising a plurality of parallel channel tubes 1 suspended in spaced relation below a ceiling slab 2.
  • the tubes have apertures 18 facing the spaces 17 between said channel tubes.
  • the channel tubes are suspended in separate mountings 3 which are provided with upper support means 11 which support carrier plates, 12 arranged between the tubes.
  • Lighting fixtures 13 are fixed to the underside of the carrier plates.
  • the mounting means have also lower support means 14 which, in the areas where the light fixtures are situated, support transparent or translucent optical under plates 15 and in the other areas support other under plates 16, such as acoustic under plates, cover plates or the like, located below the level of the mentioned apertures 18.
  • the under plates are arranged or designed in such a way that air current connection (as at 21) is ensured between the room below and the spaces in which the lighting fixtures are situated.
  • the tubes have circular cross section and are spiral-coiled made from a strip of sheet material.
  • At least some of the support mountings comprise a two-part stirrup with a top piece 4 designed to be fastened to the underside of a ceiling, a beam or the like, and a bottom piece 6 which can be vertically adjusted in relau'on to the top piece.
  • the lower part of said bottom piece is adapted to the external cross section shape of the channel tube and being connected at the top to the top piece.
  • This invention relates to a ceiling structure with air ventilated lighting fixtures mounted therein in a system arranged for supply and/or removal of air to/from the room situated beneath.
  • hung-ceiling structures comprising a plurality of hollow sections mounted in spaced relation on the under-surface of the ceiling slab and serving as mounting means for plate-shaped panels.
  • hollow sections are connected with a common collecting and distribution system to be employed in supplying and or removal of conditioned/exhaust air to/from the underlying room.
  • channel sections have been suggested shaped with mounting means for supporting plates, for example, for electrical lighting fixtures. Conduits, wires, cables and the like have been arranged in the interior of such channel sections.
  • Lighting fixtures mounted in hung-ceiling structures develop a considerable amount of heat. It has been found that for example the optical efficiency of electric lighting tubes varies with the temperatureof the tube, the maximum light output being obtained in a relatively limited temperature range. In order to increase the optical efficiency, the heat developed must be removed. The removed heat can be utilized to heat directly the underlying room, but the amount of heat being circulated to heat the room can be controlled more effectively by conducting the exhaust air from the room through the lighting fixture and thence out of the room.
  • lighting fixtures and also acoustic plates require to be repositioned and/or replaced when the activity performed in such a room has changed its character. If, for instance, the activity changes from an office activity to a workshop activity, the lighting fixtures and the acoustic panels will have to be re-arranged.
  • a purpose of the invention is to provide a so-called hung or dropped ceiling structure of the kind referred to, having a plurality of lighting fixtures arranged between the hollow sections, wherein effective cooling or ventilation of the lighting fixtures is insured.
  • Another object of the invention is to provide a ceiling structure which allows for very simple mounting of the hollow sections.
  • a further object of the invention is to provide a hung-ceiling structure which allows for quick simple .and inexpensive mounting and dismounting of the lighting fixtures with their attachments, and of the acoustic elements without the need of special tools and without skilled labor.
  • a further object of the invention is to provide a hung-ceiling having a substantially reduced depth relative to conventional structures of similar kind.
  • Yet another object of the invention is to provide a construction-which to a great extent permits the use of constructional elements of standard design, e.g. pipes, which are inexpensive and easy to obtain.
  • a hung-ceiling structure may comprise a plurality of parallel tubes suspended in spaced relation under a ceiling slab, at least some of said tubes serving as suction or pressure air conduits, being connected with collection or distribution systems, and having apertures in their walls which face towards the spaces therebetween.
  • the tubes are suspended by means of separate mounting means provided with upper support means which support carrier plates arranged between the sections, said plates carrying lighting fixtures mounted on their sides and with lower support means which, in the parts where lighting fixtures are located, support transparent or translucent optical under panels, and at other locations supporting other under panels, such as acoustic under panels, cover panels or the like, located below the level of the previously mentioned apertures.
  • FIG. 1 represents an elevation view of part of a spiral folded duct tube with insulation, stirrup suspension, carrier plate for lighting fixture and lower support sections for the under panel, and
  • FIG. 2 shows a cross section along the line ll-Il in FIG. 1, except that the tube is a conventional metal sheet tube with smooth wall.
  • a hung-ceiling construction in accordance with the example comprises a plurality of parallel channel tubes 1 of circular cross section which are arranged in a spaced relationship to each other below the ceiling slab 2. Only one channel tube is shown in the drawing, but it isto be understood that the arrangement of channel sections may be, for example as shown in FIGS. 1 or 4 in U.S. Pat. application Ser. No. 9,922 filed Feb. 9, 1970.
  • the tubes are suspended in stirrup-shaped mountings 3 each comprising a top .piece 4 and a bottom piece 6.
  • the top section 4 is shaped substantially like an U and is arranged to be fastened with its base 4a against the ceiling slab.
  • the bottom piece 6 is substantially shaped as a semi-circular stirrup fitting the section of the tubing 1.
  • the stirrup has two vertical legs 5 which have holes at their upper ends for screws 7 with nuts for fastening to the upper piece 4.
  • tongues 8 are stamped out with their free ends pointing upwardly in such a way that there is a space between the tongue 8 and the leg 5.
  • the vertical flange of an L- profile section 11 is arranged between the legs 5 of the bottom piece 6 and the tongue 8, the horizontal flange 12 carrying on the under side thereof electrical lighting fixtures 13.
  • a carrier plate 12 is reinforced by a flange 12a.
  • connection between the top piece 4 and the bottom piece 6 is so arranged that the bottom piece 6 can be displaced vertically for correct adjustment of the distance between the channel tube 1 and the'ceiling surface.
  • the side legs 9 of the top piece 4 has a T-shaped slot 10, the leg of the T being horizontal adjacent the one side of the side of the side leg, in such a way that the slot is open towards this.
  • the lower part of the bottom piece has stamped symmetrically arranged tongues 6a which point toward one another and carry the upper flangesla of an I-profile section 14.
  • the lower flanges 14b of the I-section profiles carry under plates and 16, respectively. In order to hold the under plates 15 and 16 in correct lateral position the flanges 14b are recessed as indicated in FIG. 2.
  • L-profiles 1 1 it it possible to design the upper end sections of the bottom piece 6 with outwardly pointing flanges (not shown), which in certain cases can serve the same purpose as the horizontal flanges 11a of the L-profiles.
  • the advantage of continuous L-profiles 1 1 is that one is not limited to a certain location of the carrier plates 12 in relation to the mountings 3.
  • the under plate 15 is an optically translucent or transparent plate of glass or plastic.
  • the under plate 16 is in this case 'an acoustic plate or sound-absorbent material.
  • the optical plates 15 are arranged between the channel tubes 1 beneath the lighting fixture plates 12.
  • the under plates 15 are arranged in the lengthwise direction of the channel tubes with transverse spaces therebetween.
  • the purpose of these spaces 21 is to obtain an air current connection between the underlying room and the space 17.
  • the space 17 is in air current connection with the interior 1 of the channel section, the section being provided with apertures 18 located in the lower portion of the height of the channel tube and thus below the lighting fixture carrier plates 12.
  • the apertures 18 may be fitted with pipe unions 19.
  • the channel section 1 is fitted with a split sleeve 20 of insulating material. In FIG. 1 some part of the insulation is broken off to show the spirally coiled tube.
  • the location of the plates is preferably such that the apertures 18 in the channel sections are situated approximately at the middle of the length of the optical under plates.
  • the channel tubes 1 can also be suspended by means of mountings shaped otherwise than the stirrups described in the example. What is important is that the mountings allow for an easy mounting of the channel tubes, provide upper and lower supports for the plates and that they permit adjustment of the height of the whole hung ceiling.
