Abstract: A raised access flooring system is disclosed, which comprises a raised access flooring system module comprising a space frame web which is supported by adjustable pedestals, wherein the space frame web comprises a plurality of elongate structural members and a grid. A flooring member is fixedly attached to the web. The pedestals may be positioned under the grid. Some of the elongate structural members forming the web are inclined to the flooring member while those close to the edges of the web are more vertically oriented. This space frame arrangement economizes material usage and reduces cost compared to conventional modules. The module is so configured that it can be emplaced as a member of a flooring system, and is easily removable and interchangeable.

Abstract: A device attachable to a suspended floor member (i) for collecting materials which fall through grid openings in the floor member and (ii) for controlling the rate of airflow through the grid openings in an adjustable manner. The device includes a spill container for positioning under the grid openings of the floor member in a coordinated position such that a venting path is provided for permitting airflow past the spill container from above the floor member while retaining the capacity to collect liquids and particulate matter flowing through the grid openings. Adjustable dampening structure is coupled with the spill member to provide selection of differing vent openings to control rate of airflow through the structure.
