How are joists supported?
Joists may be connected to the supporting structure at their ends using traditional carpentry joints, or they may be placed into pockets, or they may be fixed using hangers, straps or other connectors. The use of hangers rather than pockets in walls tends to reduce air infiltration and noise transmission.
How are floor joists attached?
Joists run from one beam to another and are usually spaced 16 inches apart, center-to-center. Plywood sheathing attaches to the joists, then hardwood flooring or tile. Since joists carry the load of the floor, they must be securely attached at either end to a ledger board or a beam, and must be level in all planes.
How are floor joists nailed?
Start an 8-penny nail as a toenail, 1 inch from the end of the joist and 1 inch from the bottom of the joist. Drive the toenail into the sill plate at a 45-degree angle, but do not drive it fully at this time or you will move the joist off of the layout mark.

However, avoid using any other types of screws as they cannot support joist loads and are not designed to withstand shear force.
How are joists fastened?
The joists are supported by the hangers, which are themselves fastened to the ledger boards. You can use either specialized galvanized bracket screws made specifically for joist hangers or simply use 8d or 10d nails, as indicated by the bracket manufacturer.

What are the supports between floor joists called?
Floor joist blocking refers to solid, lateral supports installed between floor joists to evenly distribute loads placed atop floor joists. Blocking uses lumber the same size as the floor joists and is fastened either in a staggered or straight line mid-span or every 8′ depending on the length of the joist.
Do floor joists have to sit on a beam?
Floor joists spread the loads bearing from above, and must be framed adequately to complete the load paths. Ideally, if a load-bearing wall runs parallel to floor joists, then it should sit directly over a beam or a joist supported by a load-bearing wall below.
Are joists load bearing?
Located between walls, beams, and foundations, floor joists are structures that support floors and most easily identified in a building’s basement or attic. Walls that run parallel to joists are not typically load bearing, whereas walls that run perpendicular to the joists are most likely load bearing.
What can I use instead of joist hangers?
Use Ledger Strips
The most common alternative to using joist hangers is a ledger strip. This technique requires a plank of wood to be secured to the outside wall and to the outside rim of the deck to create “ledges” where the joists would rest for support.
