Vibration-isolated off the wall

Equipment attaches to the wall with additional structural steel shapes, threaded rods and vibration isolators. Shapes may be welded. These steel shapes are attached to the building using concrete anchors, or masonry
anchors.

Figure 128 shows how rods, angles and struts can be used to isolate equipment attached to a wall. Angles and strut accommodate wall construction attachment points.

Vibration-isolated equipment prevents the transmission of noise and vibration into the building structure. See Figure 109 for isolator detail.

Step 1: Assemble wall frame with isolators

Accurately draw the bolt pattern on the wall using one of the following methods:

• Set the frame in place and mark the holes.
• Make a template.
• Use measurements and construction drawings to lay out the bolt hole pattern.

Step 2: Install anchors

If anchoring to concrete, install post-installed anchors.

Step 3: Attach isolators, rod, and hang equipment

Attach the isolators to framing. Attach the equipment to the isolators using threaded rod.

Piping, ductwork, and raceways may be connected.
