COLLAR BEAM Meaning and
Definition
-
A collar beam refers to a horizontal structural member that connects two opposite roof rafters or trusses near their upper ends, usually forming an inverted "V" shape. It is an essential component in roof framing that provides additional support, stability, and resistance against the spreading effect caused by the weight of the roof and external forces such as wind or snow loads.
The collar beam runs parallel to the roof slope and spans the space between two rafters or trusses. It is typically positioned at the mid-height level of the roof structure, forming a horizontal line just above the wall plate. The use of collar beams helps to prevent the rafters or trusses from spreading apart, which would otherwise put excessive stress on the walls and potentially lead to structural failure.
Collar beams are commonly found in traditional timber-framed roofs, particularly in older buildings, where they play a crucial role in maintaining the integrity and strength of the roof structure. They are often made of sturdy wood or metal and are securely fastened to the rafters or trusses using various types of connectors such as bolts or nails.
In summary, a collar beam is a horizontal structural member in roof framing that connects two rafters or trusses near their upper ends, providing additional support, stability, and preventing the spreading effect caused by the roof's weight.

Etymology of COLLAR BEAM
The word "collar beam" is derived from Old English and Middle English.
The term "collar" comes from the Old English word "coler" which originally referred to a part of a horse's harness that was worn around the neck. The word later extended its meaning to include a similar band worn by humans and eventually became associated with a stiff band or item that encircles or supports something.
The word "beam" has its roots in the Old English word "beam" which referred to a piece of timber or a large plank. Over time, the word evolved to refer to a horizontal piece of timber used in construction to support the structure or provide strength.
Therefore, the combination of the words "collar" and "beam" refers to a horizontal timber or beam that is strengthened or supported by a collar or a band.
