How Headers Work
Показать описание
A header is a beam installed over an opening which disperses the load above to the sides.
Without a header the weight above would eventually cause the wall to settle or sag.
The stud under the end of the header is called the jack.
The stud attached to the jack that runs from the sill plate to the top plate is called a king stud.
These short studs above the header are called cripples.
Often, on large openings such as garage doors, multiple jack and king studs are required.
For this building, any opening larger than 7 feet requires 2 jack and 2 king studs.
The plans called for the larger headers to be made out of LVL, laminated veneer lumber, which is stronger than conventional lumber.
All three plys of the LVL put together are less than the thickness of the 2x8 wall, so we hold them to the outside- that way there’s space on the inside for insulation like spray foam.
Here is an example of two openings over top of one another- A personnel door with an exhaust fan above. The header at the top takes care of the weight for both openings. @hausplans
