Is 3 4 Plywood Enough To Hold A Floor

Load is 2000 pound per square foot.

Is 3 4 plywood enough to hold a floor.

2x4 and 3 4 plywood will not handle that load. Other widely used plywood types include 3 4 inch which is one of the most widely used of all plywood thicknesses. So a total of four 3 foot plywood boards. A plywood subfloor generally uses 1 2 inch to 3 4 inch thick sheets of plywood that have one rough side which faces down and one smooth side which faces up.

The reason for the allowance of 1 5 fasteners is for 3 4 plywood directly over a concrete slab. If you look at old bank barns you will see people parked tractors and trucks inside. The owner of the sales lot had his bugatti parked in it when i checked it out. The bamboo install instructions say that 3 4 plywood is sufficient to support the floor.

He has sold these buildings now for years and years. The floor was surprisingly flat and took only a small amount of sanding shimming. The framing was 1 2 inch plywood deck. The floor held the tire weight with no signs of strain.

The sheets are generally 4 x 8 or 4 x 12 feet in size. This is so the fasteners don t go through the back and puncture the plastic sheeting between the slab and the plywood. Under the deck were two 1 2 inch plywood crosses plywood cut 1 2 way at the center so locked two 3 long pieces of plywood. The load it can hold usually depends on how much support it receives from adjacent wooden members.

A 12 by 36 inch piece of 3 4 inch fir plywood can support up to 50 lbs. They use real 2 or wider lumber for joists and often 10 12 deep. Bank barn is a barn built in the side of a hill. Those joists are covered by full 2 or 3 thick 2x8 or 2x10s.

Use the alternating glued veneer layers of 3 4 inch plywood make it stronger than solid wood. Floor was 2x4 pt joists 12 oc. Osb oriented strand board. It is placed near the ground with no one able to be under the floor in danger near the stream aj.

I would use 4 x 4 s or doubled up 2 x 4 s since that would be cheaper tahn 4x4 s for the corner posts. Nwfa specifies 1 5 to 2 fasteners for 3 4 solid strip and plank. However one room has solid oak in it and it appears to be sitting on a 3 8 plywood underlayment. Then use a brace 6 10 from the floor the lower the better in the corners where the braces attach which should be 2 x 4 s you want to notch the 4 x 4 posts so the 2 x 4 s fit flush.
