Copyright Goodheart-Willcox Co., Inc. 212 Section 4 Reading Prints Interior walls that carry the ceiling or floor load from above are called loadbearing partitions. Usually, they are located over a beam or bearing wall, Figure 12-13. Schedules Door and window schedules give the number and size of all doors and windows in the building. See Figure 12-14. Units listed in the schedule are referenced to the plan view with a letter or number. Some architects provide the rough opening size in the schedules to speed • King stud. A king stud is a stud located on either side of a header. It is a full-height stud that runs from the sole plate to the top plate. • Trimmer stud. Next to the king studs and below the header, trimmer studs are placed. A trimmer stud extends from the sole plate to the bottom of the header. It is attached to both the king stud and to the header. • Rough sill. A rough sill is positioned to support a window. • Cripple stud. Short studs, called cripple studs, extend between the top plate and header or the sole plate and rough sill. They are similar to trimmer studs, but are not paired with an adjacent stud. • Blocking. Blocking is used to provide structural g support and to prevent the spread of fire from floor-to-floor through stud spaces. • Top plate. The top plate (shown in Figure 12-12 as a double plate) rests above the studs. The next level e e of joists or rafters is supported by the top plate.
