In some cases additional joist supports will have to be installed before there can be extra heavy objects on the floor.
A joist support is the horizontal beam that supports the floor joists.
This beam supports the floor joists of the house s ground floor.
True floor joist span calculations can only be made by a structural engineer or contractor.
This sample table gives minimum floor joist sizes for joists spaced at 16 inches and 24 inches on center o c for 2 grade lumber with 10 pounds per square foot of dead load and 40 pounds of live load which is typical of normal residential construction.
Floor joists or beams provide the below surface support for the wood subfloor of a room.
