Function of roof beam.

Tie beam definition a horizontal timber or the like for connecting two structural members to keep them from spreading apart as a beam connecting the feet of two principal rafters in a roof truss. Ridge beam sizing is based on the span of the beam between supports and the amount of roof load supported by the beam. A structural ridge beam is a horizontal beam placed at the peak or ridge of a roof and is designed to carry much of the live and dead loads or weight of the roof structure by itself. Rafters are sloped beams that run from the roof s ridge to the eaves.

One of a series of diagonal members of the truss that meet at the apex in order to support the roof deck and its loads. Ridge beams are required by code if the roof slope is less than 3 in 12 irc section r802 3. A purlin is a horizontal piece of timber or metal which supports the roof s rafters or decking and helps to prevent your roof from sagging. A hip rafter extends from the wall plate to the ridge in the angle of a hip roof.

A roof is an essential covering that is placed on houses and buildings and even such items as automobiles. It also supports joists trusses and other roofing elements. For homes and buildings especially a roof performs multiple functions all of which are tied into providing protection. Different elements and parts of the roof provide protection to the structure s interior and exterior.

A roof beam is a load bearing member that is integral to the strength of the building. Timber lends itself to a great variety of roof shapes. Hipped roofs have four sloping sides. These roofs require hip beams or rafters.

The horizontal beam connecting two rafters that intersect at the ridge. The top ends of the rafters often meet at a ridge beam but may butt directly to another rafter to form a pair of rafters called a couple. The hip is where different roof sections meet. Each hip beam supports several smaller pairs of beams that extend out from it like branches from a trunk.

The loads on the ridge beam are carried by vertical posts at the beam ends down through the building structural walls to the building foundation. A roof beam will be the thickest and most important element of a roof or levels within a property. It supports the floor or roof above while adding integrity to walls.
