Floor Framing At Separation Wall

The wall boards are not in direct contact with the floor decking board or the flooring board.

Floor framing at separation wall.

The gap between the wall boards and the decking board is filled with acoustic sealant. A floor s framework is made up mostly of wooden joists that run parallel to one another at regular intervals. Cmu has its place especially in stair and elevator cores but for separation in a wood framed townhome its typically overkill. Building a simple partition wall a stud wall that divides an interior space without bearing any load is a perfect introduction to the basics of home construction.

Ceiling joists are usually 2 by 6s or sometimes 2 by 4s if it is an older home. The following detailing should be applied at the junction of a twin light steel frame separating wall with a light steel joist with board separating floor. Fire resistance rated wood frame wall and floor ceiling assemblies building code requirements for occupancies such as stores apartments offices and other commercial and industrial uses building codes commonly require floor ceiling and wall assem blies to be fire resistance rated in accordance with standard fire tests. All of the fire separation is actually happening in the middle gypsum board so you can put plumbing and electrical into the bearing walls without dealing with a block wall.

Your sketch should depict the floor s basic shape and layout complete with any additional features like alcoves nooks and staircases. Extremely long spans staircases or interior walls typically require additional support which can complicate your framing. Before you begin cutting or measuring grab a pencil and paper and sketch an outline of your floor. Floor joists are typically 2 by 8s 2 by 10s or 2 by 12s.

This project employs the same principles and components that are used in the construction of any frame house.
