ABSTRACT:
FIELD OF THE INVENTION
The present invention concerns panels for coffered ceilings consisting of cladding panels of sheet metal or similar material and a method for mounting such panels. More specifically, the present invention relates to coffered ceilings comprising cladding panels, each cladding panel comprises an elongated element with a constant cross-sectional profile and is mainly composed of an essentially flat principal surface enclosed by longitudinally running joining sections as well as at least one longitudinally running stiffening section bent at an angle to the principal surface.
BACKGROUND OF THE INVENTION
Profiles for coffered ceilings with longitudinal joining sections and with parts that interact for joining together are known from GB 2 307 924. U.S. Pat. No. 4,295,315 and U.S. Pat. No. 4,091,588 refer to construction panels designed for mounting by means of attachment elements that are hidden when the following profile is hooked or snapped over the attachment element of the preceding profile. In CH 343 614, the joining sections consist of a U-shaped part and a flange that is positioned in the U-shaped part of the preceding element.
None of the previously known documents show or indicate anything about profiles that while sealed allow displacement between one another and that first hook into each other once they have been drawn apart. Of the panels referred to above, only the construction panels are intended to be mounted in place without attachment elements.
SUMMARY OF THE INVENTION
One problem that is solved by the invention is that of designing the sections for joining together so that any chosen panel can simply and without the use of tools, be removed to allow access for electrical and other installations above the panels that form the coffered ceiling.
Another problem that is solved by the present invention is that of achieving a good seal between panels, yet that still allows the possibility of them being able to be drawn apart so that they can be adjusted to fit certain dimensions. The joints between the panels are designed so that they do not allow flames and hot gasses to pass though and so that the panels display good acoustic properties. In addition, the panels are designed so that they can be mounted in place without the use of any tools or attachment devices by them being positioned on and resting against the edges of beams, girders or other framing sections.
The profiles of the panels according to the present invention are specially designed to hook into each other and remain tight even if expansion due to fire or some other reason should cause them to buckle downwards.
These and other problems are solved according to the invention, in the first hand by joining sections of close-by or adjacent sections when mounted in place normally overlapping and being provided with hook-shaped folds that hook into one another only if the panels are pulled apart a short distance or if they should buckle downwards.
