Accessible concealed suspended ceiling system
A suspended ceiling system is provided comprising at least first and second parallel inverted tee-runners. Each tee-runner comprises a horizontal flange and a vertical web, with the vertical web having at least two spaced openings therein. At least one ceiling panel is associated with the parallel tee-runners. The ceiling panel has opposed side walls and opposed end walls, with a pair of first tabs formed at one end of the ceiling panel and a pair of second tabs formed at the opposite end of the panel. The first tabs are relatively longer than the second tabs and have a length sufficient so that each first tab extends through one of the spaced openings in the web of the first inverted tee-runner and rests on the flange of the first tee-runner, with the second tabs being supported by the flange of the second tee-runner.
1. A suspended ceiling system comprising at least first and second parallel inverted tee-runners, each tee-runner comprising a horizontal flange and a vertical web, the vertical web having at least two spaced openings therein; and
At least one ceiling panel, having opposed side walls and opposed end walls with a pair of first tabs formed at one end of the ceiling panel and a pair of second tabs formed at the opposite end of the panel, the first tabs being relatively longer than the second tabs and having a length sufficient so that each first tab extends through one of the spaced openings in the web of the first inverted tee-runner and rests on the flange of the first tee-runner with the second tabs being supported by the flange of the second tee-runner.
2. The suspended ceiling system of claim 1 wherein the first and second tabs are formed in the side walls of the panel and the side walls are relieved adjacent the first tabs.
3. The suspended ceiling system of claim 1 in which the openings in the web of the tee-runners and the first tabs of the ceiling panel are complementarily-shaped so as to limit the lateral positioning of the panel relative to the tee-runner and provide side-to-side alignment of adjacent panels.
4. The suspended ceiling system of claim 2 in which the openings in the web of the tee-runners and the first tabs of the ceiling panel are complementarily-shaped so as to limit the lateral positioning of the panel relative to the tee-runner and provide side-to-side alignment of adjacent panels.
5. The suspended ceiling system of claim 1 in which one or both of the pairs of the first tabs and the second tabs of the ceiling panel are formed with a shoulder for engaging an edge of the flange of the associated tee-runner to provide end-to-end alignment of adjacent panels.
6. The suspended ceiling system of claim 2 in which one or both of the pairs of the first tabs and the second tabs of the ceiling panel are formed with a shoulder for engaging an edge of the flange of the associated tee-runner to provide end-to-end alignment of adjacent panels.
7. The suspended ceiling system of claim 3 in which one or both of the pairs of the first tabs and the second tabs of the ceiling panel are formed with a shoulder for engaging an edge of the flange of the associated tee-runner to provide end-to-end alignment of adjacent panels.
8. The suspended ceiling system of claim 1 wherein one end wall of the ceiling panel is formed with an outwardly-extending flange and the other end wall is relieved to receive the outwardly-extending flange of an adjacent panel.
9. The suspended ceiling system of claim 2 wherein one end wall of the ceiling panel is formed with an outwardly-extending flange and the other end wall is relieved to receive the outwardly-extending flange of an adjacent panel.
10. The suspended ceiling system of claim 3 wherein one end wall of the ceiling panel is formed with an outwardly-extending flange and the other end wall is relieved to receive the outwardly-extending flange of an adjacent panel.
11. The suspended ceiling system of claim 5 wherein one end wall of the ceiling panel is formed with an outwardly-extending flange and the other end wall is relieved to receive the outwardly-extending flange of an adjacent panel.
12. The suspended ceiling system of claim 1 wherein one of the side walls and one of the end walls of each ceiling panel is provided with a resilient material for inhibiting vibration between adjacent panels.
13. The suspended ceiling system of claim 2 wherein one of the side walls and one of the end walls of each ceiling panel is provided with a resilient material for inhibiting vibration between adjacent panels.
14. The suspended ceiling system of claim 3 wherein one of the side walls and one of the end walls of each ceiling panel is provided with a resilient material for inhibiting vibration between adjacent panels.
15. The suspended ceiling system of claim 5 wherein one of the side walls and one of the end walls of each ceiling panel is provided with a resilient material for inhibiting vibration between adjacent panels.
16. The suspended ceiling system of claim 8 wherein one of the side walls and one of the end walls of each ceiling panel is provided with a resilient material for inhibiting vibration between adjacent panels.
