Beam attachments are hardware components used to connect hanger rods or other suspenders to the bottom flange or web of structural beams, primarily supporting piping, electrical, or mechanical systems. Selection depends on load requirements, beam flange dimensions, rod size, and whether vertical adjustment or fixed positioning is required. Common types include welded beam attachments, beam clamps, and hardware for eye bolts or lugs.
Key Types and Practical Notes
1. Welded Beam Attachments (Bottom Flange)
-
Welded directly to the bottom of steel beams to provide a secure point for rods or supports.
-
Suitable for heavy loads and large-diameter rods.
-
Some designs allow vertical adjustment; others require a nut/bolt pairing.
-
Selection considerations: load rating, flange width compatibility, and weld quality for the service environment.
2. Welded Attachments with Adjustable Features
-
Allow rod swing or vertical adjustment after installation.
-
Ideal for installations requiring precise alignment or future adjustments.
-
Check for rotation or radial movement capabilities and any additional hardware requirements (e.g., pins or cotters).
3. Beam Clamps and U-Bolt Style Attachments
-
Install without welding, clamping to the beam or strut system.
-
Convenient for retrofits or where drilling/welding is undesirable.
-
Available in various load ratings and sizes; often mount in pairs and may be tapped for threaded rods.
4. Industry Standards and Compatibility
-
Manufacturers provide figures/part numbers (e.g., Fig. 66, Fig. 20, 900 series) detailing rod size compatibility, attachment geometry, and finish options.
-
Always consult exact part numbers to ensure proper fit for beam type and rod diameter.
5. Materials and Finishes
-
Typically carbon steel; stainless steel variants available for corrosion resistance.
-
Finishes include plain, electro-galvanized, or hot-dip galvanized depending on environmental exposure.
Design Considerations
-
Load Path: Ensure both the attachment and beam flange can safely carry anticipated loads, including dynamic effects. Verify attachment load rating and beam capacity.
-
Beam Geometry: Confirm flange width, thickness, and any web features that may interfere with mounting.
-
Rod Size and Configuration: Match the attachment hole, eye, or lug size to the rod diameter and desired connection style (welded, bolted, or adjustable).
-
Installation Method: Choose welding, bolting, or clamping based on project needs, installation access, and future disassembly requirements.
-
Standards and Compliance: For structural or fire-rated applications, verify adherence to relevant codes and coordinate with structural engineers.
Information Needed for Precise Recommendations
To provide a tailored attachment selection (specific part numbers, load ratings, and mounting notes), the following details are required:
-
Beam flange width and thickness
-
Desired hanger rod size and material
-
Whether the attachment should be adjustable or fixed
-
Environment (indoor, outdoor, corrosive exposure)
