Definitions

  • the present invention relates to a high containment wall system constructed for Biosafety' Level (BSL) biological labs.
  • BSL Biosafety' Level
  • an embodiment of the high containment wall system relates to a system and structure for maintaining structural soundness and airtight conditions when subjected to deflections from seismic events under which the structure may be exposed. More specifically, an embodiment relates to a control joint assembly at the interface of the wall and ceiling in the high containment wall system.
  • the biosafety industry strives to develop standards and facilities that provide mechanisms and practices to lower the risk of unintentional infection from pathogens or biological materials in the laboratory or environmental release of those materials from the laboratory.
  • the Centers for Disease Control and Prevention (CDC) and the National Institutes of Health (NIH) have established levels of biosafety (BSL-1 to BSL- 4) to guide laboratory researchers in the safe handling of biological agents.
  • the term “high containment” refers to the higher levels of biosafety wherein enhanced protective measures are employed.
  • the walls and ceilings of a facility are one of the most dynamic areas of laboratory design. Walls and ceilings provide the main barrier in preventing the escape of biological agents from a lab facility.
  • An alternative in high containment barrier construction provides for a system of panels comprised of a homogeneous composite resin core.
  • the homogeneous composite resin core high containment barrier system provides for economies on the manufacturing and installation process.
  • An advantage of the homogeneous core is that the panels may be manufactured within tight tolerances without disrupting the structural integrity of the panel. This permits a heightened degree of uniformity of joined panels when erecting the barrier system and creates a flat, even wall surface at areas where panels are joined together.
  • the panels can be used with traditional steel studs and furring channels.
  • An embodiment of the invention comprises a track assembly for joining together a wall and ceiling for constructing a room as part of a high containment facility 7 .
  • the track assembly is comprised of a track member for placement over a wall framing stud forming a wall section of the room.
  • An engagement plate member is attached to the ceiling along the area that the wall will connect to the ceiling at the point of the track assembly.
  • An alignment bolt member is connected to the engagement plate and depends downwardly therefrom.
  • the track member has an opening on a top surface thereof to receive the alignment bolt member.
  • a flexible member is placed between the top surface of the track member and the engagement member. The flexible member has flexural rigidity' to resist excessive expansion and compression so that limited movement between the track member and engagement plate is permitted.
  • the alignment bolt is received within a grommet positioned below the top surface of the track member and sealant is provided around and within the grommet to maintain the grommet in position below the top surface of the track member.
  • the alignment bolt provides resistance to excessive lateral movement and reinforces the track assembly in preventing excessive deflective lateral movement of the wall.
  • the alignment bolt is held within the grommet.
  • the grommet and sealant have a degree of flexibility' to allow the track member to move up and down in relation to the engagement member.
  • sealant is added at points of contact around the engagement member and track member to seal off any openings that might permit air, gas or moisture leakage around or through the track assembly.
  • the track assembly enables the wall to withstand up and down movement of the wall and lateral drift of the wall that may be caused by seismic or other environmental conditions such that the necessary airtight, gastight and moisture tight conditions of the high containment lab can be maintained and to preserve the structural integrity of the wall caused by disruptive forces.
  • the track assembly can be prefabricated with the flexible member already positioned in place betw een the engagement plate and the track member such that the individual elements of the track assembly need not be serially positioned and installed in place as the wall is erected.
  • the engagement plate of the fully assembled track assembly can first be attached to the ceiling and then the wall studs be inserted into the track member that is already positioned in place. This avoids difficulties in installment that can arise from having to first attach the engagement plate to the ceiling, then attaching the flexible member to the attachment member, and then aligning the track member with the engagement plate.
  • FIG. 1 is a cross sectional view of a section of the track assembly as attached to a ceiling.
  • FIG. 2 is a cross sectional view of a section of the track assembly as attached to a ceiling and with the wall framing and wall panels attached.
  • FIG. 3 is a cross sectional view in side elevation of a section of the track assembly as attached to a ceiling with the wall framing studs connected to the track assembly.
  • FIG. 4 shows a section of the wall framing studs connected to the track assembly.
  • FIG. 5 shows a cross sectional view of the track assembly with shipping bracket.
  • An embodiment of the present invention comprises a track assembly for joining together a wall and a connective surface, such as a ceiling, for constructing a room as part of a high containment facility.
  • the track assembly 10 as installed at the joint between wall 12 and ceiling 14 is shown generally in FIG. 2.
  • Track assembly 10 comprises a track member 16 adapted to receive wall framing stud 18.
  • Engagement plate member 20 provides for attachment of track assembly 10 to ceiling 14.
  • Alignment bolt 22 depends downwardly from engagement plate 20 and extends through opening 24 in track member 16.
  • Flexible member 26 is sandwiched between the top of track member 16 and engagement plate 20.
  • An embodiment of the track assembly provides for track member 16 to be comprised of aluminum having a width of 5 inches and a thickness of 0.25 inches. Legs 30 and 32 extend downwardly from the bottom edge of upper plate 28 and are spaced 0.5 inches inwardly from each side edge of upper plate 28. Legs 30 and 32 have a thickness of 1/16 inch and extend downwardly 2 inches from upper plate 28 to form an interior channel for receiving wall framing studs. Track member 16 is constructed to facilitate project length and be provided in a number of sections spanning the entire length of the wall that joins the ceiling as seen in the partial section of wall in FIG. 4. The dimensions of the track member permit insertion of wall framing studs 18 between legs 30 and 32 as seen in FIG 2.
  • Engagement plate 20 is comprised of stainless steel and has a width of 8 inches and a thickness of 0.25 inches. It has a length corresponding to that of track member 16 to span the length of the wall joining the ceiling.
  • a series of alignment bolts 22 are secured to the underneath side of engagement plate 20. Alignment bolts 22 are positioned centrally of engagement plate 20 and depend downw ardly to be received in openings 24 in track member 16. In joining alignment bolt 22 to engagement plate 20. a threaded opening 34 is provided. Alignment bolt 22 is threaded and has a 3/8 inch diameter. Alignment bolt 22 attaches to engagement plate 20 in threaded engagement in opening 34.
  • Alignment bolts 22 are spaced along engagement plate 20 at 24 inch intervals and track member 16 has correspondingly spaced openings 24 to receive the alignment bolts.
  • a flexible grommet 36 such as a firewall grommet, is positioned through the opening 24 in track member 16 and receives alignment bolt 22.
  • Grommet 36 has circumferential flanges to enable it to be secured to track member 16 by screws or bolts.
  • Sealant 38 is placed internally of grommet 36 to fill around alignment bolt 22 as well as around the portion of alignment bolt 22 above the opening 24 to hold alignment bolt 22 in sealed relationship with grommet 36.
  • the flexible nature of grommet 36 permits relative up and down movement of track member 16 relative to engagement plate 20 to accommodate movement during a seismic event.
  • grommet 36 holds alignment bolt 22 in a flexible engagement to permit relative side to side movement of track member 16 to accommodate drift and lateral movement of the joined wall caused by a seismic event.
  • Flexible member 26 should have flexural rigidity to confer a degree of resistance to forces of compression and expansion in order to accommodate up and down movement of the wall during a seismic event such as an earthquake.
  • a suitable material that may be used for flexible member 26 is provided by the DSM System manufactured by Sika Emseal. which comprises a precompressed sealant and impregnated-foam hybrid silicone bellows. The material can be cut as needed to fit between engagement plate 20 and track member 20 and to provide a space for alignment bolt 22 to pass through as shown in FIG. 2.
  • Sealant 42 such as Sikasil® WS-295 silicone sealant, is placed around the outer edges of flexible member 26 to prevent air, gas and moisture leakage.
  • track assembly 10 Because of drying and curing times of sealant and epoxies, it can be difficult to install track assembly 10 by sequentially installing the various components in place. That is, the sealants and epoxies applied to the surfaces to be joined have short curing times and do not readily permit the engagement plate 20 to be first applied to the ceiling, followed by placement of flexible member 26 on the top of track member 16, insertion of sealant in grommet 36, and so on, all of which takes substantial time. For that reason, the track assembly 10 is preferably prefabricated of all its component parts as explained herein so that it may be installed as a unit onto ceiling 14 prior to erecting of the wall framing studs 18.
  • Bracket 44 can be provided to draw the elements together as shown in FIG. 5.
  • Bracket 44 is U-shaped and has a dimension to enable it to be placed within the channel formed by legs 30 and 32 depending downwardly from track member 16. The bottom of bracket 44 as an opening to receive the end of alignment bolt 22.
  • a nut 46 is threaded onto the end of alignment bolt and tightened to draw together track member 16, flexible member 26 and engagement plate 20. Bracket 44 can be removed once track assembly is attached to the ceiling at the area where the wall will be j oined.
