Introduction:

Hybrid room imaging equipment, as well as other ceiling-mounted equipment supported by AirFRAME®, is attached to the structure above using a bolt-on deep-channel Unistrut (P5500T) assembly manufactured by SLD. Due to the HSS tube steel frame construction of AirFRAME, we are able to provide Unistrut only at the necessary locations to support these rails. This eliminates the need to span Unistrut across the entire ceiling, maintaining structural strength and allowing for superior airflow into the surgical space.

Example Configurations

Bi-Plane Example:

Below is an example of a Bi-Plane imaging room with one C-arm, one TV Monitor, and two MAVIG tracks that are all ceiling-hung supported by AirFRAME.
Lancaster, PA, USA

Single-Plane Example:

Below is an example of a single-plane room with boom-mounted shields and TVs:

Field Leveling:

Due to overall construction tolerances (SLD factory, building structure as well as other field/site conditions), Unistrut Embeds are designed for field adjustment with provided shim-plates. Shims are pre-installed as well as shipped loose for fine-tune adjustments up and down in the field to maintain compliance with imaging manufacturer tolerances.

Installing Contractor Responsibility:

  1. Install the AirFRAME plumb, level and at the correct height relative to the finished floor or top of the finished floor plate (reference imaging equipment manufacturer specifications).
  2. Verify Unistrut is level across all pieces and withing imaging manufacturer tolerances
  3. Tools Recommended: magnetic-tip pate measure and laser level
Alert
ALERT: Lowest Strut Height Critical
Verify that the lowest Unistrut section meets the imaging manufacturer’s specified height requirement (measured from the bottom of the strut to the top of the table base plate or finished floor). Failure to meet this requirement may result in costly rework. It is significantly easier to lower Unistrut embeds than to raise the entire AirFRAME assembly or grind the floor to achieve the proper height tolerance.

Warning
WARNING: Bolt Torque Requirement
Unistrut assembly bolts are factory-torqued to 23 ft-lbs (31.18 N·m) and marked for verification.
Maintain the specified torque  both undertightening and overtightening can affect performance and long-term reliability. If adjustment is required, reinstall using the specified torque with a calibrated torque wrench.
In the case a section of Unistrut needs to be adjusted:
  1. Loosen the bolts retaining the Unistrut assembly keeping track of factory installed hardware.
  2. Remove full assembly from slot
  3. Install or remove shims as necessary
  4. Reinstall assembly into slot with all factory hardware including loc & plate washer
  5. Using calibrated torque wrench, tighten bolts to 23 ft-lbs (31.18 newton-meters)
