Final answer:
A collar tie is a structural component in roof construction that connects rafters at 2/3 the distance up from the rise, providing support and maintaining the integrity of the roof under heavy loads.
Step-by-step explanation:
A collar tie is a horizontal member that ties rafters together. It is usually installed at 2/3 distance of the rise. Collar ties are used in roof construction to prevent the rafters from spreading under heavy loads such as snow. By tying the rafters together, they maintain the roof's structural integrity. Typically, they are employed for steeper roofs where they provide essential support between the opposing rafters, positioned well above the ceiling joists to allow for attic space. A collar beam is a horizontal member that ties rafters together in construction.
A collar tie is a structural component in roof construction that connects rafters at 2/3 the distance up from the rise, providing support and maintaining the integrity of the roof under heavy loads. It is usually installed at 2/3 distance of the rise or height of the roof. This beam helps to stabilize and strengthen the roof structure, preventing the rafters from spreading apart or sagging.
