## Abstract

A bi-surfaced raised access floor panel is provided. The panel is constructed with a cross-braced framework. A generally square plate is rigidly connected to an upper surface of the framework. The plate has four corner formations and is bisected symmetrically to define first and second halves. The first halve is substantially configured as a solid load bearing surface which is adapted to support a data processing server. The second halve includes a plurality of clear perforations capable of circulating an air flow as an element of a cold aisle forming installation in a data center.

## Claims

### Claim 1

A containment system for cooling computer servers on a raised floor in a data center, comprising:
(a) a pedestal support system including a plurality of vertically extending pedestal supports each having an upper end connected to a pedestal support head and a lower end connected to a pedestal support base, said pedestal supports each connected in relation to the other in an on centers each way square matrix orientation with a plurality of horizontal stringers;
(b) a first row of bi-surfaced raised access floor panels, said bi-surfaced panels each comprising a floor panel sub-frame and a generally square plate member, said plate member having an upper working surface and a lower plenum surface, said lower plenum surface forming a built-up member connection with an upper surface of said sub-frame, said plate having four corner formations and bisected to define a first and a second halves, wherein said first halve is substantially solid load bearing surface, and said second halve is an air grate;
(c) a second row of air-grate raised access floor panels having a sub-frame and a generally square perforated air grate plate member, said plate member having an upper working surface and a lower plenum surface, said lower plenum surface forming a built-up member connection with an upper surface of said sub-framework, said plate having four corner formations; and
(d) wherein a substantially rectangular cold aisle is formed between rows of the computer servers by locating said first and second rows of floor panels in an orientation so that said second halve of said first row of said bi-surfaced floor panels are aligned adjacent to said second row of said air-grate floor panels, wherein said first and second rows of floor panels are supported on the pedestal support system, so that said perforations, in combination, are capable of circulating an airflow from a lower plenum chamber through a cold aisle formed thereby, and into a front of at least one server cabinet, and whereby at least a portion of said server cabinet is supported on said solid load bearing surface of said first halve of said first row of said bi-surfaced raised access floor panels.

### Claim 2 (depends on 1)

The containment system according to claim 1, wherein each of said corner portions further includes a diagonal clear slot, said clear slot positioned along a diagonal vector relative to the frame rails, and each of the said plates further comprising an articulating bracket, said bracket including a horizontal sheet including proximal and distal portions, said proximal portion including a central clear slot adapted to receive a threaded fastener and said distal portion including a vertically extending collar having an internally threaded clear hole adapted to receive a leveling screw, wherein said leveling screw includes a tool operating end and a foot end, said foot end adapted to bias against a pedestal head of an existing pedestal support system, and whereby said proximal portion of said sheet is slidably connected the lower surface of the corner portion with the threaded fastener extending through the central clear slot so that the articulating bracket is capable of sliding a distance which varies linearly along the diagonal vector to adjust a footprint of the floor panel for interchangeable fitment with an existing raised floor support system, and wherein the tool operating end of the leveling screw is operable through the diagonal clear slot in the peripheral portion so that the upper surface is capable of vertical adjustment and planar alignment with an existing floor panel.

### Claim 3 (depends on 1)

The containment system according to claim 1, wherein in said pedestal support system is configured on a substantially 61 cm×61 cm on centers orientation, and said upper surface of said plate members are substantially 61 cm×61 cm.
