Needle Beam

Definition

A needle beam is a steel or wood beam threaded through a hole in a bearing wall, used to support the wall and its superimposed loads during the underpinning of its foundation.

Purpose

The primary purpose of a needle beam is to temporarily support a structure during foundation repairs or modifications. It allows the load to be transferred from the wall to the beam, providing stability while work is carried out on the foundation.

Examples of Use

• Underpinning: Used in underpinning projects to stabilize existing foundations while new supports are installed.
• Wall Support: Provides temporary support to bearing walls during renovations or repairs that require foundation alterations.
• Building Relocation: Employed in building relocation projects to support the structure as it is moved to a new location.

Related Terms

• Underpinning: The process of strengthening and stabilizing the foundation of an existing building.
• Shoring: Temporary supports used to hold up structures during construction or repair work.
• Bearing Wall: A wall that carries structural loads from the roof, floor, or other parts of the building.

Notes

• Installation: Proper installation of needle beams is critical to ensure the safety and stability of the supported structure.
• Load Distribution: Needle beams must be positioned and secured correctly to effectively distribute the loads they support.
