Floor span connector Ī connector for connecting wall studs of two adjacent floors in a light frame building structure, the connector having a first attachment tab, a seat member, a diagonally slanted support leg, and a second attachment tab, all substantially planar. In that case a twist strap connector can be used. This can only be done where the rafter or trusses are immediately above or immediately to the side of studs below. When the strengthening is being done from the inside, the ideal connector to use is one that connects rafters or trusses directly to wall studs. They resist uplift at the heel of a truss economically. Twist straps provide a tension connection between two wood members. However, toe nailing & end nailing is nowhere near as effective as using hangers to support flooring systems.
Rafter tie code#
Although the use of steel joist hangers to support floor joists is recommended over a ledger supporting the joists because of house settling and nail separation, they are not required by code in most municipalities. Subfloor isn't load bearing in residential construction. Using screws instead of nails is also highly recommended to prevent the aforementioned creaking and other problems as well. It is important to note that when laying wooden subfloor to apply adhesive to the joists which the subfloor will lay on to help prevent creaking & lateral movement and separation of the joists and subfloor. Joist hangers are used to prevent floor joists, which is what supports the flooring systems in residential homes and buildings built using lumber, from dropping and twisting thus creating an uneven walking surface. To give added strength in increase various load requirements over wood only. Top mount, face mount, sloped/skewed, and variable pitch hangers for dimensional lumber, engineered wood I-joists, structural composite lumber and masonry wall. Seismic tie provides facility to securely fix cabinets, bookcases, desks, appliances, machinery & equipment to walls and/or floors to constrain their movement during earthquakes. These devices are also known as wind clips and hurricane side clips A tie which is attached to roof tiles to keep them from blowing off a roof.They are also known as hurricane ties or strips These devices are primarily used in areas affected by high winds including hurricanes and are generally suitable for any area that may be impacted by windstorm damage. A connecting tie that provides a continuous structural load transfer path from the top of a building to its foundation, helping to protect buildings from damage resulting from high wind.Ī hurricane clip has two meanings in building construction:
Rafter tie install#
Hurricane clips meet the minimum requirements for code approval and are only as strong as their weakest install point which is generally half the strength of the wood.
Rafter tie windows#
Among the most common style used along the Gulf Coast of the United States are plywood fasteners or oriented strand boards over the windows and openings of brick homes. They are also known as hurricane clip or strips. Ī connecting tie that provides a continuous structural load transfer path from the top of a building to its foundation, helping to protect buildings from damage resulting from high wind. Įach of the crucial connections in a structure, that would otherwise fail under the pressures of high winds, have a corresponding type of tie, generally made of galvanized or stainless steel, and intended to resist hurricane-force and other strong winds. Hurricane ties are in place at the top of the wall as the roof trusses are being placed.Ī hurricane tie is used to help make a structure (specifically wooden structures) more resistant to high winds (such as in hurricanes), resisting uplift, racking, overturning, and sliding.
