The present invention relates generally to modular demountable wall systems and more particularly, to a flexible and versatile demountable wall system for where control of air pressure and contaminants may be required.
Demountable wall systems are frequently employed for partitioning room space between an overhead and a floor. The walls can be constructed of wall panels, fabric, sheet rock, etc. which are incorporated into the frame work assembly using either a batten or rolled form snap configuration. The finished or exposed area of a wall surface includes no fasteners. Demountable wall systems can be comprised of prefabricated components including, but not limited to, a supporting framework with support or frame members generally extending vertically from floor to ceiling, wall panels, a means for attaching the panels to the framework, and various trim elements. The wall panels may be held in the framework by battens or by snap-in arrangements wherein the panels have edge flanges engaging recesses in the frame members.
Demountable wall systems may be provided as single-sided, having wall panels on only one side of the framework, or as double sided, having wall panels on both sides of the framework. In double-sided configuration, either the framing elements must have wall panel attachments on both sides, or two sets of one-sided framing elements must be used back to back.
Demountable wall systems may be used as enclosures in which a highly sanitary or an uncontaminated environment may be maintained, also know as “Cleanrooms”. A “Cleanroom” is a specially designed & constructed room in which the air supply, air distribution, filtration of air supply, materials of construction, and operating procedures are regulated to control airborne particle concentrations to meet appropriate cleanliness levels. Cleanrooms have controlled environments in which variables such as the density of airborne particles per cubic meter or the temperature of the room are controlled. For example, Cleanrooms are often used in facilities for the manufacture and assembly of electronic components, or in the biological and pharmaceutical sciences. Cleanrooms are essential for these manufacturing processes, which require high degrees of cleanliness and/or precise temperature and humidity control.
The need for Cleanrooms that can control the level of contamination (e.g. particulate and/or biological, etc.) in the sub micron particle range is increasing. Typical systems have been created to meet a single use, as the requirements for use in electronics, photonics, aerospace, trace metals, pharmaceutical, and for biological safety containment. These varieties in applications require wall systems with different configurations and functional requirements.
The walls and corners of Cleanrooms should have generally flat and smooth surfaces which tend not to catch and accumulate dust and other contaminants and which will not interfere with a laminar flow of room air. The wall surfaces must be smooth and durable to facilitate cleaning. The vertical seams between panel edges should be sealable, even when one or both panel edges have been field cut. The details of the panel edge connections should not interfere with the installation of the panel in tight spaces.
Cleanrooms are classified according to the number and size of particles permitted per volume of air provided in the enclosure. A discrete-particle-counting, light-scattering instrument may be used to determine the concentration of airborne particles, equal to and larger than the specified sizes, at designated sampling locations. The ISO 14644 Standards were based on from previous US Federal Standard 209E Airborne Particulate Cleanliness Classes in Cleanrooms and Cleanzones (abbreviated as the FED-STD-209E standard), which referred to the number of particles of size 0.5 μm or larger permitted per cubic foot of air. The ISO 14644-1 Standards specify the decimal logarithm of the number of particles 0.1 μm or larger permitted per cubic meter of air. For example, an ISO class 5 Cleanroom has at most 105 particles per m3.
Several performance considerations are important in the design, manufacture, and installation of demountable wall systems, including such systems for use in the design, manufacture, and installation of Cleanrooms. For example, it can be desirable that the components of the wall systems have the ability to be delivered to site and with a minimum of field fabrication and installed “clean”. When installed, the wall should present a smooth surface for ease of cleaning. The system should be installable in as little space as possible, as floor space costs are significant. Variations or movement in the floor or ceiling should be accommodated. As such, Cleanrooms typically require modification to meet site conditions during construction, have the ability to be relocated, and should be flexible to allow the system to be easily reconfigured to meet changes required for production and equipment changes. These changes are typically required to be made “clean” so they can be installed during or with little disruption to production.
Previously existing wall systems have failed to satisfy one or more of the above-mentioned criteria. Thus there is an unmet need for a demountable wall system that requires a minimum of field fabrication and can be built “clean”, is economically manufactured, is easily installed in a minimum of space, and is suitable for use in a variety of Cleanroom configurations or as an office or lab partition and otherwise meets all the aforementioned criteria.

The embodiments of the present invention shall be more clearly understood with reference to the following detailed description of the embodiments of the invention taken in conjunction with the accompanying drawings, in which:
The description which follows, and the embodiments described therein are provided by way of illustration of an example, or examples of particular embodiments of principles and aspects of the present invention. These examples are provided for the purposes of explanation and not of limitation, of those principles of the invention. In the description that follows, like parts are marked throughout the specification and the drawings with the same respective reference numerals.
In the description and drawings herein, and unless noted otherwise, the terms “vertical”, “lateral” and “horizontal”, are references to a Cartesian co-ordinate system in which the vertical direction generally extends in an “up and down” orientation from bottom to top (z-axis) while the lateral direction generally extends in a “left to right” or “side to side” orientation (y-axis). In addition, the horizontal direction extends in a “front to back” orientation and can extend in an orientation that may extend out from or into the page (x-axis). In the description and drawings herein, and unless noted otherwise, the use of the term “upper” generally refers to or indicates the area or direction towards a ceiling of a cleanroom, while the term “lower” generally refers to or indicates the area or direction towards a floor of a cleanroom.
Although the foregoing description and accompanying drawings relate to specific preferred embodiments of the present invention as presently contemplated by the inventor, it will be understood that various changes, modifications and adaptations, may be made without departing from the spirit of the invention.
In Cleanroom design, there are many factors to consider before a settling on a final design and beginning Cleanroom construction, including but not limited to, (i) the activity level within the Cleanroom; (ii) the type of activity required within the room; (iii) the contamination rate from any such activity; (iv) the temperature and humidity required for the activity, and; (v) the comfort of the associates that will work within the Cleanroom. Once all of these factors are analyzed, a design can be formulated, using guidelines that have been established, which will lead to a successful “operational” Cleanroom system. Over design will cost the owner additional up front cost, and operational cost, and under design will result in production problems. These issues can be addressed utilizing the flexibility of the present invention.
The present invention is directed to a system that may be installed as a modular demountable space partition or wall system, and be used for various configurations, including, but not limited to Cleanrooms. The system of the present invention was designed to have components, which would easily fit together in a semi-rigid fashion and can be more securely attached with the use of self-tapping screws for ease of installation and retrofit. The system can also be easily disassembled and/or re-configured with minimal disruption, effort, cost and loss of materials. The system can be assembled or disassembled with reduced debris so as to be a “clean” construction. When used in association with Cleanrooms, the present invention can be used with a new installation but also can be used where upgrading, modernizing, or expanding existing Cleanrooms are required (e.g. a retrofit).
According to the present invention, the construction of Cleanrooms can now be reduced to a set of construction members that can quickly and releasably secured together but can also be quickly disassembled. Accordingly, the complex prior art process of constructing a Cleanroom wall system may be now reduced to a series of steps that automatically result in proper alignment and sealing of wall junctions in order to meet the technical and functional requirements of a specific Cleanroom design.
The present invention provides a system that does not require precise preplanning, as other wall systems, which once installed, do not allow modification or adjustment. The modular system of the present invention is intrinsically a flexible system such that it may be possible to change the Cleanroom layout before, during, and after assembly. The present system provides a demountable wall system for use with Cleanrooms that includes construction components or members that are versatile and easy to assemble, owing to a universal locking mechanism. The components are designed to easily and securely align with the other components so as to secure wall panels as desired.
In the case of existing Cleanrooms, it may be possible to use the present invention in whole or in part. It will be understood by a person skilled in the relevant art that individual embodiments of the present invention can be used with preinstalled or preexisting systems and/or equipment. It will also be understood that, depending on any pre-existing or pre-installed configuration, not all embodiments of the present invention may be used. For example, where a ceiling may not be required, as there may be a pre-existing or installed ceiling, the system of the present invention can be used without any ceiling components. It will also be understood that where doors or windows are not required, they can be omitted as well. One aspect of the present invention, therefore, may be the flexibility of the system. It can also be adjusted after installation without significant effort or cost. Further, debris that can result from current systems may be significantly less that existing systems, which meant that post-installation modifications can be made quick, cost effective and with minimal disruption of existing activity within the Cleanroom and surrounding environment. It will be done in a “clean” manner without the need to create dust, debris, and any type of scrap incompatible with production areas. In many cases, the unused production material can be recycled as well. This may not be possible with pre-existing Cleanroom systems.
The present invention is directed to a framed wall construction system that can be easily assembled and disassembled. For the framed wall construction system in accordance with the present invention, the construction material may be fabricated by extrusion, using materials such as aluminum, composites or other suitable materials. It will be understood that any suitable material with functional characteristics (e.g. strength and flexibility requirements) may used with the embodiments of the present invention. Preferably, the embodiments of the present invention are made of a manufactured lightweight material, preferable extruded aluminum or engineered polymers (e.g. PVC, etc.). More preferably, construction material of the present invention may be extruded aluminum as it reduces contamination from metals that can rust and add additional contamination, and it provides construction material that can be completely recycled at end of the life of the system or components. In doing so, the system of the present invention provides for a “clean construction” in that the amount of material that cannot be re-used or recycled may be reduced.
The system of the present invention involves a plurality of construction members comprising, track members (e.g. ceiling and floor track members), attachment members (e.g. differently sized generally “H” shaped brackets and generally “L” shaped brackets), structural members (e.g. stud members and ceiling support members), batten members, and wall/ceiling panel members that can be releasable interconnected to form a variety of Cleanroom configurations. Using a small set of differing types of construction members, a near infinite number of different combinations can be achieved
An aspect of the present invention includes attachment members, which may comprise generally H-shaped brackets and L-shaped brackets of differing sizes. Both the H-shaped brackets and the L-shaped brackets are produced from, preferably, extruded aluminum and then cut and shaped to meet the requirements of any particular assembly.
The structural members include, but are not limited to, stud and ceiling support members, which provide the structural frames for the system of the present invention. Wall studs may be used vertically (e.g. functioning as a wall stud) and/or horizontally (e.g. functioning as a cross member) to hold the wall panels, corners, doorframes, windows and batten members in place. In a preferred embodiment, wall studs may be secured to ceiling and/or floor track members with H-brackets and/or L-brackets. In the system of the present invention, the studs and other structural elements can be single sided or double sided in order to accommodate single or double wall panels. A preferred double stud (see, for example,
Another aspect of the present invention is a ceiling suspension system designed to support a suspended ceiling, preferably for use in Cleanrooms. In one configuration, ceiling support members, preferably extruded aluminum, and more preferably shaped as generally inverted “T”s (see
The suspended ceiling system for use in association with the present invention may incorporate a framework or grid formed from ceiling support members, which could be set out lengthwise or crosswise so as to form open areas for mounting substantial loads. The preferred embodiment of the present invention utilize two generally inverted T shaped support members, which when affixed to the building structure and used in accordance to loading tables known to a person skilled in the relevant art, can be used to support ceiling panels, air filter modules, light fixtures, sprinkler heads, high efficiency particulate air (“HEPA”) filtration, mechanical & electrical components and the like. In a preferred embodiment, the suspended ceiling of the present invention can provide a walkable ceiling structure.
Separate heating, ventilating and air conditioning (“HVAC”) system may provide a controlled, reproducible environment for the Cleanroom as well as a comfortable environment for those working in the facility. The cleanliness of any Cleanroom may be directly proportional to the air change rates of the air moving through the room. Because the air volumes supplied to Cleanrooms are many times (10-100) greater than those supplied to conventionally ventilated rooms, the capital and operating costs for the construction of such rooms can be very high. Hard, smooth, durable finish materials have been used in the construction of the Cleanroom to allow for routine cleaning and sterilization. Floor finishes, are typically seamless smooth surfaces, which are subject to the requirements of the Cleanroom.
The track members include, but are not limited to, ceiling tracks and floor tracks. The ceiling/floor tracks may anchor the stud members and wall panel members to the ceiling support members or the floor, as applicable. The present invention utilizes at least two track styles, each of which can be used for ceiling and floor applications. Floor track members may be required to adapt to any floor level irregularities, which are common. It will be understood that each track style can be used for both ceiling and floor applications. In other words, it may be possible to use the same track as both a ceiling track and floor. When used as a ceiling track, the tracks of the present invention may function as one or both of a fixation point for the stud members and holding any ceiling panels in place.
The system uses batten members including, but not limited to, wall battens and track battens, to hold wall panels in place and provide the profile and/or configuration that may be required by the technical requirements of each Cleanroom. In a preferred embodiment, a wall batten secures wall panels in place in vertical and horizontal orientations while track battens secure wall panels in place in horizontal orientations, particularly at floor and ceiling applications. It will be understood, however, that track battens may also be used to secure wall panels in place in a vertical orientation. Batten members can be made of variety of materials well known in the art. Preferably, batten members may comprise a solid material, preferably made of co-extruded poly vinyl chloride (“PVC”) or extruded aluminum, as a securing or holding mechanism where two construction members (i.e. wall panels and ceiling support members, wall panels and floor track members, etc.) join together. An aspect of the invention may be interchangeable batten members of differing configuration to be used in Cleanrooms configured for use in association with different requirements, such as, for example, electronics manufacture, pharmaceutical manufacture or biological containment. In a preferred embodiment, the system can utilize batten members of co-extruded PVC that allows for a tight seal, with little caulking required for reduced maintenance. The length of each batten member may vary and will be determined based on the height of the wall system required as well as locations of equipment ports at various positions along the wall system. In typical Cleanrooms, a floor cove may be integrated into the floor system. This decreases the versatility of the Cleanroom incorporating this design. In a preferred embodiment of the present invention, batten members (e.g. coves or coved batten members) may be incorporated into the wall system, which allows for flexibility in the relocation of the wall system as changes are required.
Sealants (e.g. silicone, latex, etc.) may be applied to all joints and gaps to fill all voids between construction materials, devices, and installed equipment. In a preferred embodiment of the present invention, extensive caulking may not be required to maintain the functional characteristics of the Cleanroom.
An aspect of the present invention provides a system that allows the use of any wall panel that will be suitable for specific Cleanroom classifications (e.g. ISO 14644 Standards), and that also meet any applicable local building codes requirements. In a preferred embodiment, the wall panel can have a ½″ thickness but it will be understood that the embodiments of the present invention could be sized for and function with a variety of wall panel thicknesses (see, for example,
Each wall panel section generally includes an interior face and an exterior face. Typically, the interior face may form a planar surface, which provides interior wall structure to the clean room assembly, while the exterior face may not be provided in the Cleanroom but external to the clean room. It will be understood that a wall panel in Cleanroom construction can have two interior wall faces. The demountable wall system of the present invention allows for the formation of a single or double wall system. While many Cleanroom wall systems provide for a solid single panel, a preferred embodiment of the present invention provides for a double-sided “cavity wall” installation. A double-sided “cavity wall” allows for piping, electrical, mechanical, etc. to be integrated within any location along the wall. Alternatively, the invention may utilize a single sided panel, using specific embodiments for attaching mechanical and electrical components. With this wall option, it would not be necessary to create a double wall with two partitioned walls panels.
Another aspect of the invention may be a locking mechanism comprising an interlocking snap configuration that provides a semi-rigid universal connector. An embodiment of the present invention may be a plurality of locking mechanisms that allow for quick connection and quick release of different construction members of the present invention. Once connected, the locking mechanism of the present invention forms a semi-rigid connection between two construction members (e.g. track member and stud member). Having an interlocking mechanism allows for quick assembly and disassembly of the various elements of the present invention and thus provides for the versatility of the present invention. An aspect of the present invention is a first releasable snap connector on a first construction member, the first snap connector having a unidirectional engagement member adapted to engage or mate with a second releasable snap connector on a second construction member. The first and second releasable snap connector, when in mating engagement, are opposingly oriented (e.g. oriented in opposite directions) along a linear plane of movement so as to secure the first and second construction members along the linear plane of movement. In order to engage the snap connectors, a pawl member biased in a resting first configuration can be moved when forced is applied to it, preferably from a pawl member of a second snap connector, to a second extended configuration. In a preferred embodiment, when the pawl may be biased towards the second position (e.g. by a force applied by second pawl), the first pawl provides resistance to the applied force. Once the force is released, the first pawl returns to the first resting configuration. The second pawl may travel against the first pawl pushing the first pawl to the second extended configuration until it clears the first pawl at which time, the first pawl is released and returns to the first configuration. It will be understood that as the first pawl is biased to the second position, so will be the second pawl; as the first pawl is released, so is the second pawl. So long as the second releasable connector travels in a first direction along the linear plane, the pawl of the first releasable connector allows the second connector to travel until the second pawl no longer biases the first pawl towards the second position. In other words, the pawl of the first releasable connectors fits into or engages with the pawl of the second releasable connector and therefore the second releasable connector can only travel freely in the first direction along the liner plane. Once the force is taken away, the pawl member returns to the first position such that it can engage with or snap into the second pawl member. In order to release the snap connector, the construction member can be moved perpendicularly to the linear plane so as to basis the pawls to the section position thus release the engagement of the two pawl members. Once the pawl members have been released, the construction members can be separated. It will be understood, as described in greater detail in reference to the drawings that having a plurality of releasable connectors allows for secure semi-rigid attachment of construction members but this secure attachment can be released with the application of sufficient force perpendicular to the linear plane of movement in order to release the pawl members.

Stud 100 can be used for either a double wall panel configuration (e.g. wall panels provided in all recesses 101 to 104) or a single wall panel configuration (e.g. wall panels provided in only 101 and 102 as shown in

It will be understood that with the use of wall panels of existing configurations, demountable cleanrooms can be produced using the construction members of the present invention.

Releasable snap connectors 105 and 108 of stud member 100 have a unidirectional engagement member adapted to engage or mate with the releasable snap connectors 1605,1603 and 1604,1606 on corner frame member 1600. The releasable snap connectors 105,108 and 1603,1604, for example, when in mating engagement, are opposingly oriented (e.g. oriented in opposite directions) along a linear plane of movement, which corresponds to the vertical or z-axis, so as to secure stud 100 and corner frame 1600 along the linear plane of movement of the vertical or z-axis. In order to engage the snap connectors, pawl member 1605, biased in a resting first configuration, may be moved when forced is applied to it by pawl member 105 moving towards corner frame member 1600, so as to move pawl 1605 towards a second extended configuration. When pawl 1605 is biased towards the second position (e.g. by the force applied by pawl 105), pawl 1605 resists the applied force. Once the force is released (when pawl 105 no longer engages pawl 1605), pawl 1605 returns to the first resting configuration. Concurrently, pawl 105 travels against pawl 1605 pushing pawl 1605 to the second extended configuration until pawl 105 clears pawl 1605 at which time, the force is released and pawl 1605 returns to the first configuration. It will be understood that as pawl 1605 is based to the second position, as will be pawl 105; as pawl 1605 is released, so is pawl 105. So long as pawl 105 travels in a first direction along the linear plane, pawl 1605 allows pawl 105 to travel until the pawls are no longer biases towards the second position. In other words, pawl 1605 fits into or engages with pawl 105 and therefore pawl 105 can only travel freely in the first direction along the liner plane (e.g. z-axis) thus forming a semi-rigid connection. Once the force is taken away, the pawl members return to their first position such that they can engage with each other. In order to release the snap connector, the construction member 100 and 1600 can be moved along the y-axis so as to release the engagement of pawl members 105 and 1605 and 108 and 1606. Once the pawl members have been released, the construction members 100 and 1600 can be separated. It will be understood that having a plurality of releasable connectors allows for secure attachment of construction members but this secure attachment can be released with the application of sufficient force perpendicular to the linear plane of movement in order to release the pawl members.
It will also be understood that a variety of construction members can be secured using the releasable snap connectors or locking mechanism of the present invention. For example, in

By the utilization of the construction members of the present invention, demountable cleanrooms, laboratories or office partitions can be built. It will also be understood by a person skilled in the art that the construction members of the present invention can be assembled together to create any number of combinations of Cleanroom laboratories or office configurations. Using the configurations possible with the various construction members, it may be possible to construct a Cleanroom within a predefined space quickly and easily. It allows infinite configuration possibilities that allow existing Cleanrooms to adjust the initial design when the requirements change. It will also be understood by a person skilled in the relevant art that the invention is not limited to configurations set out herein. The present invention provides a system that does not require precise preplanning, as other wall systems, which once installed, do not allow modification or adjustment. The modular system of the present invention may be intrinsically a flexible system such that it may be possible to change the Cleanroom layout before, during, and after assembly. In the case of existing Cleanrooms, it may be possible to use the present invention in whole or in part. It will be understood by a person skilled in the relevant art that individual embodiments of the present invention can be used with preinstalled or preexisting systems and/or equipment.
The preferred installation method may be to start from a ceiling, preferably attaching track member 800, and preferably using a level to install a track member 700 at the floor. From there the installation could, in a preferred embodiment, progress to the walls studs, and then framing the installation of windows and doors. After the panels are installed, the battens members are selected and can be used to seal the wall system.
It will be apparent to those skilled in the art that the present disclosure is merely by way of example, and is not to be construed as limiting upon the following claims.
