Ceiling with stabilizing frame
A ceiling with stabilizing frame 1 comprises a frame, a plurality of ceiling plates, and a plurality of fastening devices, Each of the fastening devices is placed at an inner side of one of the side plates of one of the ceiling plates and has a threaded hole, The frame has a plurality of mounting bars, which are connected with cover plates of the ceiling plates on upper sides thereof by holding screws, which are respectively engaged with the threaded holes of the fastening devices, Thereby load on the ceiling plates is spatially distributed, so that an increased maximum load and an enhanced lifetime of the ceiling is achieved.
The present invention relates to a ceiling with a stabilizing frame, particularly to a ceiling with a stabilizing frame that is invisible and assembled using bolts.
BACKGROUND OF THE INVENTIONIn a clean room, commonly a ceiling is used which has ceiling plates mounted on a frame. Since the frame is exposed, dust and dirt easily gather thereon, creating a hygienic problem.
As shown in
For performing installations above the ceiling plates, it is occasionally necessary to have human workers to wall thereon, so that maximum allowed load thereof is important. In conventional art, however, as described above, the ceiling plates 3a are carried by the frame 2 via the mounting plates 7a only, which are relatively small, so that load is concentrated on small areas. Furthermore, the cover plates 31a and the side plates 32a are typically made of metal sheets of a thickness of only 0.5 mm, which limits maximum load. Hence accidents easily happen, furthermore, the ceiling 1a has a limited lifetime.
SUMMARY OF THE INVENTIONThe main object of the present invention is to provide a ceiling with a stabilizing frame of increased maximum load and increased lifetime.
For achieving above objects, the present invention comprises a frame, a plurality of ceiling plates, and a plurality of fastening devices. Each of the fastening devices is placed at an inner side of one of the side plates of one of the ceiling plates and has a threaded hole. The frame has a plurality of mounting bars, which are connected with cover plates of the ceiling plates on upper sides thereof by holding screws, which are respectively engaged with the threaded holes of the fastening devices. Thereby load on the ceiling plates is spatially distributed, so that an increased maximum load and an enhanced lifetime of the ceiling is achieved.
Other aspects and advantages of the present invention will become apparent from the following detailed description, taken in conjunction with the accompanying drawings, illustrating by way of example the principles of the present invention.
As shown in
Referring to
The frame 2 has a plurality of mounting bars 22, which are connected with cover plates 31 of the ceiling plates 3 on upper sides thereof by holding screws 23. The holding screws 23 are respectively inserted into the threaded holes 42 for fastening the ceiling plates 3. Each of the mounting bars 22 has a central elevated plate 25 with mounting holes 26, through which a mounting rod 28 passes. Each of the suspension rods 28 comprises a threaded rod 282, which passes through the hole 26, and a fastening element 281 at a lower end of the threaded rod 282. For each mounting rod 28, the threaded rod 282 at an upper end thereof is fastened to one of the height-adjusting devices 13 of the upper structure 11, and the fastening element 281 has a larger diameter than the mounting hole 26. Alternatively, the mounting rods 28 are welded to the lower plate 25 (not shown). Thus the fastening devices 4 are enabled to hold the ceiling plates 3 with distributed load, so that increased maximum load and enhanced lifetime are achieved.
Furthermore, the ceiling plates 3 are preferably respectively fixed at four corners thereof for stable connecting thereof.
