Do hurricane ties go on both sides?
These ties are designed to attach to connect the wall’s top plate with the truss rafter. For maximum lift resistance, they can be installed on both sides of the rafter or joist.
What side do hurricane ties go on?
The recommended location of the roof to top plate hurricane ties is on the exterior side of the wall (same side as the structural sheathing) when this method is used.
Can I use screws for hurricane ties?
Why not use screws? However, the risk if construction screws are used in steel connectors such as hurricane tie-downs is that such screws might break under load across the screw diameter even though their screw design resists pulling out of the wood.
Are hurricane ties required on rafters?
Building codes in hurricane areas, and areas where high winds can be expected, require the installation of metal ties, or straps as follows: “Roof assemblies shall have rafter and truss ties to the wall below. All new buildings are required to have hurricane ties installed.
How many nails do you need for a hurricane tie?
The Simpson Strong-Tie H3 Clip is part of the Hurricane Tie System that features various configurations of wind and seismic ties for trusses and rafters. A typical H3 installation ties the single top plate to the rafter or truss. The Simpson H3 requires (8) 8d joist nails.
What kind of nails do you use for hurricane ties?
While many hurricane ties have been evaluated with 8d x 1½” nails for compatibility with nominal 2x roof framing, some require the use of a longer, 8d common (2½” long) nail and others require a larger-diameter 10d nail.
Are hurricane ties required?
All new buildings are required to have hurricane ties installed. While not required on older structures, owners of existing buildings would be wise to invest in the installation of hurricane ties and straps. Costs are minimal and these retrofitted items can make a difference during the next hurricane or wind event.
Can I use hurricane ties instead of joist hangers?
Hurricane ties will not usually be required by your local building department, but they are a cost-effective method of securing your joists over a cantilevered beam that may be lifted by high winds.
How many hurricane ties are needed?
Each truss or rafter needs two hurricane straps: one for the front and one for the back.
What is a hurricane tie?
A 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.
What are hurricane ties?
Hurricane Ties. Hurricane ties are hardware pieces that connect the joists to cantilevered beams to reduce uplift forces caused by high winds. These are inexpensive and are a good precaution to use wherever high winds may be a problem, especially in zones where hurricanes and tornadoes are common.
What are hurricane straps?
Hurricane straps can be used to reinforce a deck house or a residence of any type, as long as the building has a wood frame. Hurricane straps are perforated bands of galvanized steel that reinforce connections between structural members of a wood frame building.
What is a hurricane tie down?
Hurricane tie-downs or HVAC tie-down straps are exactly what they sound like: an attachment that anchors your outdoor condensing unit to the platform or base that it sits on. In many cases, tie-downs are installed with the system, particularly in areas where hurricanes are common. HVAC hurricane tie-downs come in a variety of styles.
