A collar tie is a structural component that is used in building construction to provide support and stability to the roof or ceiling framework. It is typically a horizontal piece of wood or metal that is installed between two opposing rafters or joists near the ridge of the roof. The collar tie serves to prevent the rafters or joists from spreading apart, which can cause the roof to sag or collapse. It also helps to distribute the weight of the roof evenly across the walls of the building, which can prevent structural damage over time. Collar ties are an important part of building construction, particularly in areas that are prone to high winds or seismic activity. They help to prevent the roof from lifting or shifting during a storm or earthquake, which can cause significant damage to the building. Collar ties are also important for ensuring that the roof remains level and stable over time, which can help to prevent leaks and other issues. In addition to providing support and stability to the roof, collar ties can also be used for decorative purposes. They can be designed in a variety of shapes and sizes, and can be painted or stained to match the rest of the building's decor. Some collar ties are even designed to be exposed, adding a unique architectural element to the building. Overall, collar ties are an essential component of building construction, providing both structural support and aesthetic appeal. They are an important consideration for architects and builders alike, and should be installed correctly to ensure the safety and longevity of the building.

Collar ties are structural components of a building’s roof or ceiling that provide an opposing force to the rafters and joists, thereby creating a stable and secure framework for the construction. The collar ties are typically connected from one rafter to the opposite rafter and run parallel to the ridge of the roof. They are typically made of metal or wood, and are used to support the rafters and joists in order to ensure structural integrity and provide stability. Collar ties are also used to secure the roof from uplift, to reduce swaying and to prevent the roof from collapsing. They can also provide additional support for the walls and gable ends of the building.

Masonry collar ties are a type of tie beam that reinforces the masonry structure of a building. They are pieces of timber or metal that are installed at the intersection of two walls and connected to both walls, forming a truss-like structure. The collar tie is used to prevent outward movement of walls from the force of gravity, wind, and any other lateral load. It also helps to keep the walls plumb, preventing them from leaning over time. Collar ties are also used to provide lateral support to the roof structure, which helps to prevent the roof from collapsing in the event of an earthquake or other seismic event. The collar ties should be installed correctly, as incorrect installation can lead to structural failure and significant damage to the building.
