the term “hangers” typically refers to structural elements used to suspend or support various components within a building or structure. These hangers are often used to carry the weight of systems such as HVAC (heating, ventilation, and air conditioning), electrical wiring, plumbing pipes, and other utilities. They are essential for maintaining the stability, functionality, and safety of a structure.

Hangers are commonly made of steel, although other materials such as aluminum or reinforced concrete may also be used depending on the specific application. The connection of hangers to the main structure is crucial to ensure their effectiveness and durability. Here are a few common types of hanger connections:

  1. Welded Connections: Welding is a commonly used method to attach hangers to structural members. It involves fusing the hanger and the supporting beam or structure through the application of heat and melting a filler material. Welded connections provide high strength and rigidity when properly executed.
  2. Bolted Connections: Bolts are used to connect hangers to the main structure. This involves drilling holes through the hanger and the supporting beam or structure and inserting bolts through them. Nuts and washers are used to secure the connection. Bolted connections allow for easier installation, adjustment, and potential disassembly when required.
  3. Clamped Connections: Clamps or brackets can be used to connect hangers to structural members. These connections typically involve wrapping a clamp around the hanger and the supporting beam or structure and securing it with bolts or other fasteners. Clamped connections are often used in situations where adjustability or temporary installations are required.

The specific type of hanger connection used depends on various factors, including the load requirements, structural design, material properties, and the specific application. The connection design should consider factors such as load capacity, safety, serviceability, and the potential for fatigue or corrosion.
