Different Types of Hold-Downs
- Hold-downs to the foundation
- Hold-downs that connect a shear wall to the foundation are
- bolted, screwed or nailed to the end stud or added post.
- Retrofit hold-downs anchor the wall to the footings using a threaded rod.
- One end of the rod is adhesive set into a hole drilled in the foundation concrete.
- Rod transfers the uplift force from the wall down into the foundation.
- Hold-downs connect walls through the floor
- Hold-downs that connect two walls through a floor come in pairs; one above and one below.
- Figure shows an example of hold-downs connecting the wall of a second story to a first story wall.
- The hold-downs are bolted, screwed or nailed to their respective end stud or added post.
- Uplift forces are then transferred from the wall above to the wall below through the threaded rod that is bolted to the hold-downs.
