Tie rods are often used with clevises and or turnbuckles.
Roof tie rods.
Trusses having a more contemporary appearance may utilize steel tie rods for some members.
In age old timber frame buildings like the gothic cathedrals of the middle ages enormous stone buttresses stabilized the walls allowing for graceful arched beams to create a beautiful timber ceiling.
Wall systems whether brick or timber must be properly anchored to the sub.
A tie rod assembly is used to brace steel columns or heavy timber beams or used to support canopies and awnings.
Material and coating options are the same as that discussed in our timber truss hardware section.
If it s just a hook it s probably ok to keep it on and attach it to one of the rod eyeholes.
If you don t want to drop any more cash you can tie the rods to your built in roof rack on your own.
Our tie rod calculator will quickly determine rod lengths when given overall pin to pin dimensions of a tie rod assembly.
This article describes and illustrates the different types of support that prevents roof sagging and wall bulging at buildings including definitions of collar ties rafter ties and structural ridge beams.
A rafter tie forms the bottom chord of a simple triangular roof truss.
When ceiling joists run perpendicular to the rafters inspectors may find rafter ties installed above ceiling joists as framing members every 4 feet running above the ceiling joists connecting opposing rafters.
Tie rods are supplied with left hand and right hand threads so that they may be rotated and tensioned after truss fabrication.
Some of these can support the roof and prevent ridge sagging and wall spreading.
Tie down rods transmit the uplift forces caused by wind down through the walls into the ground.
Tie rods bolting and clevises can be sourced to go with the steel fabrications.
They can get beat up in the wind and even fly off if they aren t tied on correctly.
Rafter ties should be at least 2 x 4 inches nominal.
Tie down and hold down rods are integral in securing the roof structure and bearing ends of beams to limit the potential hazard of roof uplift during storms and severe weather.
Certified engineering can be provided if required.
Swc can source these rods in a variety of diameters lengths and materials along with appropriately sized clevises to create a clean pinned connection to attachment points.
We can manufacture and supply structural tension systems and tie rods in many specifications and finishes.
However sometimes a standard off the shelf item isn t suitable for a particular application.
By using extensive in house facilities we can manufacture specials to suit customer requirements.
Steel tie rods solve the age old problem of roof construction.
They hold the walls from bending out as the roof is loaded with wind or snow.
