What is a truss floor system?
Herein, what is a floor truss?
Floor trusses are built with 2x4s or 2x3s with a wide, stable bearing surface that is easier to work on and around. The spacing of floor trusses allows for maximum structural efficiency and speed of installation. Stiffness and strength can be designed into the floor truss, creating a more solid floor.
One may also ask, can floor trusses be used for roof trusses? So "floor" trusses can be used in roof applications, and built on the same jigs as "normal" flatwise trusses, the only difference usually is that the end verticals are sloped and some kind of bearing block or other accommodation is made to allow the sloping truss to rest comfortably on the flat bearing surface.
Also asked, what is the difference between a floor joist and a floor truss?
Joists are used in floors and as column support. The joist (also called Bandsill) supports the load which the floor is built to bear. It is like the skeleton a building. Trusses are of many types; the simplest is a planar truss which is used as a roof support system.
How much do engineered floor trusses cost?
Floor trusses are going to run around $4.40 per lineal foot, spaced 2′ on center, this makes the cost per square foot for the joists at $2.20. For a floor span of over 24′ trusses are certainly the way to go.
