Abstract

Disclosed is a design for an environment cell (cleanroom) of modular assembly with self-supporting walls and ceiling. Pneumatic inflation of walls and roof is created by a continuous flow of filtered air driven from the base of each module. Cells are portable, easy to erect, deflate and store for re-use elsewhere. Three variations of cell can be interconnected flexibly into any utility configuration required by the user.

Modular Construction Environment Cell

       Disclosed is a design for an environment cell (cleanroom)
of modular assembly with self-supporting walls and ceiling. Pneumatic
inflation of walls and roof is created by a continuous flow of
filtered air driven from the base of each module.  Cells are
portable, easy to erect, deflate and store for re-use elsewhere.
Three variations of cell can be interconnected flexibly into any
utility configuration required by the user.

      A system for the simple construction of a controlled
environment work cell, such as a cleanroom specification, is shown in
Fig. 1.  It is a completed work unit cleanroom constructed within a
warehouse with various modular building components and configured to
provide a layout that may be of various shapes, widths and lengths.
Typical modular building components employed are End Wall units 30,
Personnel entrance/exit units 31, and Link units 32.  A cross section
through a cell is shown in Fig. 2.  Fig. 3 shows a typical modular
building and some of the components that would be assembled together
to make up cells.  Each cell module would be assembled using a base 1
which is the key to the system, containing within itself a
fan-assisted air intake system 2, via air vents 3.  Adjacent to the
air intake and also integral to the base is an air filter tray 4.
Both the air intake system 2 and the air filter tray 4 run the length
of the base 1.  Also integral to the base is a service corridor 5
which carries the necessary service facilities to support the cell
module:  e.g., vacuum, pneumatic and electrical lines.  Service
connection points 6 are available at set positions on the base top
surface to support the work unit.  The base end panels 7 carry
quick-fit connectors enabling base service lines to connect through
to other interconnecting modules.

      Attached to the top surfaces of base 1 are the upper tent units
13.  The floor of the tent unit 13 is perforated similarly to the top
surface of the base 1.  When both units are assembled the perforated
flooring allows air to pass from the upper tent unit 13 to the base 1
without restriction.  Part of the upper tent uni...
