Nail through the top plates and the header into ends of the cripple studs. Nail through the plates into the ends of the king studs and through the sides of the king studs into the ends of the header. Nail through the top and bottom plates into each end of the common studs.
What is the stud that holds up a header?
Jack studs and king studs The header is supported by a jack stud at each end. Jacks, sometimes called trimmers, fit under each end of a header, and they transfer the load that the header carries down to the bottom plate and the framing beneath.
Are king studs load bearing?
To be the king stud, it must travel from plate to plate and be immediately next to the end of the header. Some walls support things above, and some don’t. Walls that support loads are called load-bearing or bearing walls. Walls that don’t carry a load are termed nonbearing.
Can I use an existing stud as a king stud?
When a rough opening is cut in a wall, sometimes one or both existing studs around the opening can serve as king studs. These must be of the same size lumber as the other wall framing, except the header. (Unlike the header, the sill rests on its side.) The length of the sill must equal the width of the rough opening.
What is a jack stud in framing?
A jack stud is a stud that has been cut down to be placed above and/or below an opening. The jack stud provides support to the lintel trimmer and sill trimmer.
How many jack studs go under a header?
The header rests on two “jack” studs abutted by two “king” studs. Leave the area beneath the header open when framing in a door, or add the “cripple” studs at the bottom of the sill if framing in a window.
What are king studs for?
A king stud is a specialized type of stud which is used in post and beam construction to support an opening such as a door or window. Many building codes specifically require the use of king studs to make openings sturdier, and to increase overall structural stability.
Is a king stud necessary?
The king stud on either side of the frame bulks up the support around an opening, compensating for the fact that studs have been omitted to make room for the opening. When a new home is built, king studs are usually required around doors and windows.
Should headers be glued?
Glue is okay but no codes call for it. The ends of the header need to be nailed into the king studs (the ones the header fits between) and generally a header that long would need double trimmers under each end. (Also called jack studs, they go under the header and should be tight).
What kind of studs are used for headers?
The header is supported by a jack stud at each end. Jacks, sometimes called trimmers, fit under each end of a header, and they transfer the load that the header carries down to the bottom plate and the framing beneath. Nailed to the jacks are full-height studs called king studs; they support the assembly between the plates.
How many Jack and King studs on a header?
The number of jack and king studs installed on each side of a header shall comply with Table R603.7 (1). King, jack and cripple studs shall be of the same dimension and thickness as the adjacent wall studs. Headers shall be connected to king studs in accordance with Table R603.7 (2) and the following provisions:
How are box beam headers connected to King studs?
Headers shall be connected to king studs in accordance with Table R603.7 (2) and the following provisions: For box beam headers, one-half of the total number of required screws shall be applied to the header and one-half to the king stud by use of C-shaped or track member in accordance with Figure R603.6 (1).
How is a jack stud connected to a king stud?
There are a few ways to skin that cat analytically but, in the interest of keeping things simple, my recommendation would be to ensure that you’ve got enough lamination nailing in the middle third of the stud group height to laterally transfer 2% of the total axial load on the stud group from the jack stud to the king stud.
