Attached carports can use the supporting structure as framing for one of the sides.
Carport post footing size.
A carport s post size will vary depending on the height of structure.
That would certainly work but i am into less concrete by doing the isolated big footings the carport is 36 long x 24 wide w 12 tall columns and a 12 12 roof it is pretty grand w timber trusses 12 o c.
The footing should be about 16 x 16 or 18 dia.
The width or diameter can vary from 350mm wide to 600mm wide with the depth varying from 750mm to 1 5m and more.
Use a power auger or post hole digger to dig post holes of about two to four feet deep for the footings.
Depth of footings below the natural and finished grades shall not be less than 24 inches for exterior and 18 inches for interior footings.
Footing is truly sufficient.
2 lengths of 4 1 2 rebar at 90ยบ in the footing 4 total.
Supporting the ridge beam thanks.
People often ask us what size footings do they need to concrete the carport posts into the ground.
Doesn t need to be pretty.
My question is weather or not an 8 dia.
You could use a slightly too long 4x4 to wedge up the end of the beam to relieve the pressure on the post.
A good rule of thumb is to be sure it will be as high as the tallest person or vehicle who plans to use your carport.
Minimum specification for a carport post up to 8 feet high is 4 by 4 inches.
Leave extra length to be sure you have enough.
They should be at least 101 inches long.
How big the footings or foundations are depends on several factors.
Set a simpson epb44 in the new footing to accept the bottom of the post.
Footing systems on expansive soil shall be constructed in a manner that will minimize damage to the structure from movement of the soil.
The footings will be set 2 5 below finished grade and i ll use simpson strong tie elevated post base anchors epb66 so that i can lay pavers on top of the footing with the pergola post resting on the anchor base at the finished grade of the patio.
Depending on size of carport you may need to have one additional support post at the halfway mark on both the left and right sides for a total of six.
