Abstract:
1. A method of installing a suspended ceiling comprising the following steps: a. creating main joists for the suspended ceiling by securing j-shaped main subcomponents together back to back and end to end so that joints formed between the main subcomponents on one side of the main joist are staggered with respect to the joints formed between the main subcomponents on the other side of the main joist, and creating branch joists for the suspended ceiling by securing pairs of j-shaped branch subcomponents together back to back with their ends flush with each other to form each branch joist, b. suspending the main joists from the purlins of a building employing pairs of brackets that attach on either end of a rod so that an upper bracket of each pair of brackets attaches to one of the purlins and a lower bracket of the pair of brackets attaches to one of the main joists and the length of rod located between the pair of brackets adjusts to a desired length to allow the main joists to be suspended with the main joists level, parallel with each other, and spaced a desired distance apart, c. securing the branch joists approximately perpendicular to the main joists and a desired distance apart from each other so that the two ends of each branch joist secure to adjacent main joists and so frames are formed by the main and branch joists for supporting ceiling panels, d. placing ceiling panels in each frame formed by the main and branch joists.
