Definition

Noun: A lally column is a structural support column used in building construction. It consists of a vertical steel cylinder (pipe) that is filled with concrete to provide strength and stability, typically used to support beams or floors in a building's framework.

Usage

A lally column is a specific type of architectural and engineering component. It is used as a permanent load-bearing support within a structure. * The basement renovation required installing two lally columns to support the main beam. * The engineer specified a lally column at this point to carry the load from the floor above.

Advanced Usage

• Technical Specification: In construction documents, a lally column's dimensions (diameter, length) and load-bearing capacity are precisely specified.
  • The architectural plans call for a 4-inch lally column with a 10,000-pound capacity here.
