![]() By connecting the opposing rafters, collar ties effectively create a triangular shape, forming a rigid framework that distributes the roof’s weight evenly across the supporting walls.Ĭollar ties play a vital role in resisting the lateral forces that can occur due to various external factors, such as wind uplift or seismic activity. The primary of collar ties is to resist the outward thrust or spreading force exerted by the roof’s weight, preventing the walls from pushing out and maintaining the structural stability of the entire building. They are usually positioned horizontally, perpendicular to the rafters, and are secured in place using appropriate fasteners. ![]() Typically installed parallel to the ground, these ties span across the width of the roof, connecting two opposing rafters at an elevation just below the peak. Definition of Collar TiesĬollar ties, also known as collar beams, are horizontal members that connect opposing rafters near the upper third of the roof. In this section, we will explore the and purpose of collar ties, shedding light on their significance in roof construction. Definition and Purpose of Collar TiesĬollar ties are an essential component in the construction of roofs, serving a crucial purpose in maintaining the stability and structural integrity of the overall framework. Discover their benefits, building code requirements, and frequently asked questions. ![]() Learn about the definition, purpose, and installation differences between collar ties and rafter ties. ![]()
