Abstract

Claims (32)

1 . A cleanroom ceiling support system comprising:

a ceiling support section comprising:

a set of perimeter sticks configured to be assembled to define a perimeter of the ceiling support section;

a set of interior runner sticks configured to be assembled within the perimeter defined by the set of perimeter sticks and orientated in a first direction;

a set of interior cross sticks configured to be assembled within the perimeter defined by the set of perimeter sticks and orientated in a second direction;

a first mounting bracket configured to connect any combination of perimeter and interior sticks; and

a second mounting bracket configured to connect any combination of perimeter and interior sticks;

wherein each perimeter stick of the set of perimeter sticks has a first cross-sectional profile, and wherein each interior runner stick of the set of interior runner sticks and each interior cross stick of the set of interior cross sticks have a second cross-sectional profile; and

wherein the first cross-sectional profile is half of the second cross-sectional profile such that two adjacent and oppositely facing perimeter sticks of the set of perimeter sticks form the second cross-sectional profile.

2 . The cleanroom ceiling support system of claim 1 , wherein the second mounting bracket is configured to secure an accessory received therethrough.

3 . The cleanroom ceiling support system of claim 1 , wherein the first direction is substantially perpendicular to the second direction.

4 . The cleanroom ceiling support system of claim 1 , wherein each of the first mounting bracket and the second mounting bracket are configured to:

slidingly couple to a first stick; and

fixedly couple to a second stick, the second stick is substantially perpendicular to the first stick.

5 . The cleanroom ceiling support system of claim 4 , wherein the first stick is either a perimeter stick of the set of perimeter sticks or an interior runner stick of the set of interior runner sticks, and wherein the second stick is any one of the perimeter stick of the set of perimeter sticks, the interior runner stick of the set of interior runner sticks, or an interior cross stick of the set of interior cross sticks.

6 . The cleanroom ceiling support system of claim 5 , wherein the ceiling support section comprises a plurality of ceiling support sections, the plurality of ceiling support sections comprises:

a first section; and

a second section, each of the first section and the second section can be assembled in a first location and installed in a second location.

7 . The cleanroom ceiling support system of claim 5 , wherein the set of perimeter sticks comprises:

first and second perimeter sticks having a first length and assembled substantially parallel to one another; and

third and fourth perimeter sticks having a second length, each of the third and fourth perimeter sticks are connected to the first perimeter stick and the second perimeter stick and assembled substantially parallel to one another and substantially perpendicular to the first and second perimeter sticks,

wherein the first, second, third, and fourth perimeter sticks define the perimeter of the section.

8 . The cleanroom ceiling support system of claim 7 , wherein each interior runner stick of the set of interior runner sticks is configured to be assembled substantially parallel to the third perimeter stick and the fourth perimeter stick and substantially perpendicular to the first perimeter stick and the second perimeter stick.

9 . The cleanroom ceiling support system of claim 8 , wherein each interior cross stick of the set of interior cross sticks is configured to be assembled substantially parallel to the first perimeter stick and the second perimeter stick and substantially perpendicular to the third perimeter stick and the fourth perimeter stick.

10 . The cleanroom ceiling support system of claim 9 , wherein each interior runner stick of the set of interior runner sticks has a third length, and each interior cross stick of the set of interior cross sticks has a fourth length that is less than the third length.

11 . The cleanroom ceiling support system of claim 10 , wherein each interior runner stick of the set of interior runner sticks is assembled offset from one another within the perimeter and extending between and connected to either the first and second perimeter sticks or the third and fourth perimeter sticks.

12 . The cleanroom ceiling support system of claim 10 , wherein each interior runner stick of the set of interior runner sticks is connected to the first and second perimeter sticks or the third and fourth perimeter sticks by any combination of two of the first or second mounting brackets.

13 . The cleanroom ceiling support system of claim 12 , wherein each interior cross stick of the set of interior cross sticks is assembled within the perimeter and is connected to:

one of the first, second, third, or fourth perimeter sticks and one interior runner stick of the set of interior runner sticks; or

a first interior runner stick of the set of interior runner sticks and a second interior runner stick of the set of interior runner sticks.

14 . The cleanroom ceiling support system of claim 13 , wherein each interior cross stick of the set of interior cross sticks is connected by any combination of two of the first or second mounting brackets.

15 . The cleanroom ceiling support system of claim 14 , wherein each perimeter stick of the set of perimeter sticks, each interior runner stick of the set of interior runner sticks, and each interior cross stick of the set of interior cross sticks each comprises a slot configured to receive a fastener configured to couple either a first mounting bracket or a second mounting bracket to the respective stick.
