Definitions

  • This invention relates to ceiling structures providing an interior or false ceiling formed of plates and suspended from a supporting ceiling.
  • Such ceiling structures are generally known and are usually formed as radiant heating ceilings having heating pipes arranged in the interspace between the supporting ceiling and the interior ceiling, or as ventilation ceilings, having openings in the 1nterior ceiling for the purpose of circulating air.
  • Such a ceiling may also be built as sound absorbing ceiling.
  • the ceiling structure comprises downwardly depending bolts anchored in the supporting ceiling, horizontal supporting beams secured to said bolts, and plates forming the interior ceiling, said plates having upturned marginal portions each provided with a lateral flange resting on one of said beams.
  • the pipes of a device for radiant ceiling heating may also be carried by the said beams.
  • Fig. l is a vertical section, taken across the supporting beams, of a first embodiment of the invention
  • Fig. 2 is a vertical section of a second embodiment
  • Fig. 3 shows a modification of Fig. 2
  • Fig. 4 is a vertical section of a third embodiment
  • Fig. 5 shows a modification of the structure shown in Fig. 4,
  • Fig. 6 is a vertical section of a fourth embodiment
  • Fig. 7 shows a section on the line VII-VII in Fig. 6, and
  • Fig. 8 is a vertical section analogous to Fig. 1, through a fifth embodiment of the invention.
  • the numeral 1 designates a supporting ceiling, made e.g. of concrete, the underside of which is provided with a lining 2. Threaded bolts 3 passing through the lining 2 and projecting downwardly are anchored in the supporting ceiling 1. Threaded on the free end portion of each bolt 3 are two nuts 4. The bolts 3 are arranged in parallel rows. The bolts 3 of each row of bolts project through openings provided in a channel-section supporting beam 5, which is adjustably secured to the bolts 3 by means of the nuts 4.
  • each of the channel-section beams 5 has a lateral flange 5a. Seated upon each longitudinal flange 5a are the horizontal legs of the upturned and mutually abutting edge portions 6 of two adjacent plates 7 of the interior ceiling. It is not necessary to fasten the legs of the edge portions 6 to the longitudinal flanges 5a. Instead of extending horizontally, the longitudinal flanges 5a of the beams 5 and the legs of the edge portions 6 of the plates 7 resting on the flanges can be slightly inclined. It is to be understood that the channel-section beams 5 can also be provided with lateral flanges 5a on both sides.
  • a very simple suspension device for the interior ceiling is provided by the parts 3, 4, 5 and 5a.
  • This suspension device for the interior ceiling simultaneously serves as a support for the pipes 8, placed ice between the interior ceiling 7 and the supporting ceiling 1, 2 and forming part of a system for radiant ceiling heating.
  • the pipes 8 extend transversely of the channel-section beams 5 and rest upon the latter. A special fastening of the pipes 8 on the channel-section beams 5 is not required. Contrary to known radiant heating ceilings, the pipe system of the heating equipment thus has no inde pendent suspension on the supporting ceiling.
  • the plates 7 of the interior ceilings may be perforated and/or be provided with a sound absorbing lining on their upper face.
  • the supporting beam 5' is L-shaped in section and is secured to the bolt 3 by its shorter horizontal leg.
  • the longer leg 9 of the beam 5 projecting downwardly in vertical. direction, is provided with a plurality of equidistant slots 10.
  • the upturned marginal portions 6' of the plates 7' forming the interior ceiling are provided with a number of horizontal tongues 11 engaging within the slots 10 and the number of which correspond to that of the slots 10..
  • the height of the slots 10 and the height of the edge portions 6' are so selected that, when for instance the plate 7', shown at the left in Fig.
  • the embodiment of the invention shown in Fig. 3 has beams 5a of U-section.
  • the beams 5a in this case are secured by their webs to the bolts 3, while the two de pending legs 9a of the channel-section beam are provided with slots 10a.
  • the plates 7a in this construction meet each other in a vertical plane extending through the respective row of bolts.
  • the marginal portions 6a of the plates 7a are bent upwards symmetrically with respect to the said plane of separation and engage within the slots 10a of the associated leg 9a, each by a row of horizontal tongues 11a.
  • the plates can be removed or inserted merely by pressing one plate upwardly and moving the other plate in transverse direction.
  • the embodiment shown in Fig. 4 has profiled beams 5b of U-shaped cross-section, the web of which is fastened to the bolts 3.
  • the edge portions 12 of the downwardly projecting legs 13 are outwardly bent at an angle.
  • the marginal portions 6b of the sheet metal plates 7b which meet in a plane extending vertically through the row of bolts are bent towards the beam 5b in a manner symmetrical to the said plane, and comprise upwardly extendmg resilient edge portions 14 corrugated in longitudinal direction.
  • These resilient edge portions 14 of the plates are slipped over the outwardly bent edge portions 12 of the beam legs 13, so that each plate 711 is releasably clamped between two adjacent beams 51: by means of its edge portions 14.
  • the plate 7b shown at the left in Fig. 4 is forced upwardly until the edge portion 12 of the beam leg engages the bottom groove of theassociated edge portion 14, of that plate, then the plate 7bsituated at the right hand side, can be grasped by its left edge and can be released from its clamp
  • the suspension means for the interior ceiling also serves as a supporting means for the pipes 8, which are disposed be tween the plates 7 and the supporting ceiling 1 (Fig. 2) and form part of a system for radiant ceiling heating.
  • the pipes 8 extend transversely of the beams 5 and rest on the latter; separate suspension members for the heating pipes 8 will thus be saved.
  • a plurality of equidistantly spaced rows of horizontal guide rails are embedded in the supporting ceiling 1.
  • the rails 3.5 are of hollow rectangular cross-section and have a longitudinal slot 16 in their lower wall. At one end of the hollow section rail 15, its lower wall of the section is completely cut away in order to provide an entrance opening 17 (Fig. 6).
  • the hollow section rail 15 is tightly anchored in the supporting ceiling 1.
  • the head 3a, of a threaded bolt 3 extending downwardly through the slot 16 is supported so as to be horizontally disnlaceable.
  • the bolts 3 of each row of bolts project each through a longitudinal slot 19 (Fig.
  • each beam 5d in the supporting beam 5d extending at right angles to the guide rails 15 of each row, said beam being adjustably secured to the bolts 3' by means of two nuts 4.
  • a lateral flange 5a (Fig. 6) of each beam 5d supports the horizontal leg of the upturned and mutuall abutting marginal portions 6 of two adjacent plates 7 of the interior ceiling. It will be understood that the profile .of the supporting beams 5d as well as the mode in which the plates 7 engage these beams could ditfer from the arrangement shown in the drawing.
  • the beams 5d of the ceiling structure shown in Figs. 6 and 7 also carry the pipes 8 of a system for radiant ceiling heating, said pipes being arranged between the interior ceiling 7 and the supporting ceiling 1, 2 in a direction transverse to that of the beams 5d.
  • the bolts 3' during assembly of the ceiling can be easily aligned in a row owing to their movable suspension in the rails 15. in order to bring the beams 5d into exactly parallel positions.
  • the longitudinal slots 11 provided in the beams 5a allow for relatively large inaccuracies in the mutual spacing of the bolts 3 and guide rails 15. respectively, within each row.
  • a nut could be provided at the respective end of the bolt.
  • means could be provided for fixing the bolts 5' in their position on the guide rails.
  • the shanks of the bolts could be threaded their entire length and a further nut could be provided on each bolt 3' below the slotted lower wall of the guide rails 15 for tightening the head 3:]. on the latter.
  • the opening left in the insulating layer 2 for mounting the rail 15 can be filled with insulating or sound absorbing material after the bolts 3' and the beams 5d have been mounted.
  • the guide rails 15' are not embedded in the concrete ceiling 1, but are screwed to the underside thereof.
  • the guide rails are provided with end flanges 20 having slots 20a, through which fastening screws 21 extend.
  • the rails 15' could be secured to the bottom face 4 of the concrete ceiling 1 by means of suitable elements other than these screws 21, e.g. by means of skirts embedded in the concrete.
  • the bolt 3' the shank of which is threaded over its entire length, is fixed to the guide rail 15 by means of a nut 22.
  • the recess provided in the insulating layer 2 for attaching the rail 15' to the ceiling 1 subsequently is filled up with insulating material 2a.
  • the arrangement of the guide rails ,15' described with reference to Fig. 8 is particularly adapted to provide existing ceilings with an interior ceiling 7 and with a system for radiant heating.
  • a ceiling structure comprising a support, a plurality of hangers depending from the support, a plurality of spaced beams adjustably supported by said hangers a sufficient distance below said support to carry pipes on the upper surfaces thereof and having longitudinally extending supporting portions spaced below said upper surfaces, and ceiling boards having upstanding vertical walls on two opposed sides, projecting hanger portions connected to the upper edges of said walls, said hanger portions being supported by said longitudinally extending supporting portions with adjoining walls of adjacent boards substantially in abutment, there being a substantial free and uninterrupted space below the hanger portions to permit pivoting of one end of the boards about the longitudinally extending portions near the other end of said boards, said supporting portions being spaced below said upper surfaces a distance at least equal to the height of said walls to permit one of said abutting walls to be moved vertically to enable relative lateral shifting between adjacent boards for removing and replacing a selected board without removing adjacent boards.
  • a ceiling structure comprising a support, a plurality of hangers depending from the support, a plurality of pipes, a plurality of spaced beams adjustably supported by said hangers a sufiicient distance below said support to carry said pipes on the upper surfaces thereof and having longitudinally extending supporting portions spaced below said upper surfaces, and ceiling boards having upstanding vertical walls on two opposed sides, projecting hanger portions connected to the upper edges of said Walls, said hanger portions being supported by said longitudinally extending supporting portions with adjoining walls of adjacent boards substantially in abutment, said beams being arranged to provide a free and'uninterrupted path for the hanger portions above said supporting portions for a distance at least equal to the height of the walls, said supporting portions being spaced below said upper surfaces a distance at least equal to the height of said abutting walls, said hanger portions being flat with the hanger portions on both sides of said boards projecting in the same direction, said longitudinally extending portions projecting from said beams in a direction opposite to that of the hanger portions, there
