Claim:
A panelized ceiling for a cleanroom, the ceiling comprising: a plurality of constructed panels, each panel including: an internal load bearing member; a polygonal top face placed on top of said internal load bearing member; a polygonal bottom face placed under said internal load bearing member; at least three sides connecting said top face to said bottom face in such a manner as to enclose said internal load bearing member, at least two of said sides being arranged so as to angle inward toward said internal load bearing member from the edges of said bottom face, each of said at least two sides including at least two independent mounting holes therein; a plurality of hooks, each of said hooks including: a main body with a distal and a proximal end and a length therebetween; at least two prongs, arranged toward said distal end of said main body and extending from said main body toward said proximal end at an acute angle to said length; and a connector located toward said proximal end; and a plurality of rods, each of said rods being connected to an overhead support and having a distal connector; wherein, said ceiling is formed by attaching a proximal end of said rod to said overhead support and said distal connector of said rod to said connector of said hook; placing one of said prongs on each hook through one of said mounting holes in a first of said plurality of panels and a second of said prongs on said same hook through one of said mounting holes in a second of said plurality of panels; and repeating said step of placing until all panels are attached to at least two hooks; wherein, said bases of said first and said second panels are adjacent and closer to each other than said tops of said first and said second panels; and wherein said hook attached to said first and said second panels does not contact either of said bases of said first and said second panels, and does not contact said load bearing member.
