This is contrary to my understanding of the purpose of bridging.
Cross members between floor joists.
Look inside old homes or warehouses and you ll often see funny cross.
How do i keep them even.
The rim joist fig.
Tom silva explained that the cross bridging transferred the load on the joist to the other joists thus strengthening the floor.
Yet it is not uncommon to find bridging not properly installed or missing all together.
The common spacing between floor joists is 16 inches on center.
It should be placed at eight foot intervals between any floor joists 2x10 or longer.
Proper bridging distributes the load on the floor to other joists and over time prevents floors from sagging and squeaking do to floor joists twisting and warping.
Building code requires the use of blocking for floor joists that exceed 2 inches in width by 12 inches in depth.
Providing more support and rigidity than cross bracing solid blocking is a reasonable alternative but can be an obstacle for running plumbing pipes and electrical wire between floor joists.
Removing a floor hvac vent is the best way to check for total floor thickness.
A lot of questions revolve around joists when it comes to building a deck.
If you have central heat and or air conditioning with floor vents it is very easy to remove the vents by pulling them straight up.
In general terms joists spaced 16 inches on center can span 1 5 times in feet their depth in inches.
A 2x8 up to 12 feet.
The cool thing about these however is that the space between cross members is usually big enough to accommodate big pipes even ductwork.
Blocking is also needed each time the joist overlaps with a center beam and every eight feet between two joists.
B the framing member that runs around the perimeter of your house and that the floor joists butt into often gets riddled with large holes.
How far apart are floor joists placed.
Solid blocking should be used where floor joists overlap over beams.
Be aware that lumber yards have a far greater inventory of floor joists than the home centers or big box stores.
I just watched an episode of ask this old house which dealt with cross bridging between wood floor joists of a house.
2x10 to 15 feet and 2x12 to 18 feet.
What is the proper placement.
With the vent removed you have a wide clear view of a cross section of your floor.
A joist is a horizontal structural member used in framing to span an open space often between beams that subsequently transfer loads to vertical members.
