Proper Shed Floor Joist Support

Gather the proper lumber to cut your floor joists rim joists and 2 two band boards and 4x4 skids.

Proper shed floor joist support.

The amount of weight a 2 8 can support is going to depend on the span of the joist and how far apart it is from the next joist. Solid blocking should be used where floor joists overlap over beams. So what is the proper shed floor joist spacing. The runners are set back from the shed frame the distance of the overhang.

Cut all floor joists to proper length along with your 2 rim joists and two band boards and skids. If your storage shed is going to be larger then you will want to put in a middle support beam that goes the opposite direction of the way your joists are hanging. The distance between the two points should be 5 feet. The screw jacks support the floor joists and keep them out of contact with the ground.

Set batter boards and mason line to mark the perimeter of the posts that support the runners. After cutting all lumber mark off your two band boards for joist layout at 12 on center. Although a 2 6 can span 11 10 a span 8 feet or longer should have a center support beam. Since you can span 13 with a 2 8 spf joist on 16 inch centers but you ultimately decide to only span 8 feet with your joist on 12 inch centers the weight.

It should be placed at eight foot intervals between any floor joists 2x10 or longer. The spacing of both joists and bearers will be governed by the type of structural floor decking that is used. View of underside of shed deck. Also cut your 4 x 4 skids to length.
