LH-Series Joists have been standardized in depths from 18 inches (460 mm) through 48 inches (1,200 mm), for spans through 96 feet (29,000 mm). DLH-Series Joists have been standardized in depths from 52 inches (1,300 mm) through 120 inches (3,000 mm), for spans up through 240 feet (73,000 mm).
[5] [3] As a rule of thumb, the depth should be 1 ⁄ 24 of the span. [5] The width of the ribs is typically 130 mm (5 in) to 150 mm (6 in), and ribs usually have steel rod reinforcements. [5] The distance between ribs is typically 915 mm (3 ft). [3] The height of the ribs and beams should be 1 ⁄ 25 of the span between columns. [3]
The term binding joist is sometimes used to describe beams at floor level running perpendicular to the ridge of a gable roof and joined to the intermediate posts. Joists which land on a binding joist are called bridging joists. [3] [4] A large beam in the ceiling of a room carrying joists is a summer beam. A ceiling joist may be installed flush ...
Wood furring strips typically measure 1 x 2 or 1 x 3 inches. They can be laid out perpendicular to studs or joists and nailed to them, or set vertically against an existing wall surface. The spacing between the strips depends on the type of finishing material. Wider spacing is typically used behind the heavy boards that support ceramic tiles.
Wall framing in house construction includes the vertical and horizontal members of exterior walls and interior partitions, both of bearing walls and non-bearing walls. . These stick members, referred to as studs, wall plates and lintels (sometimes called headers), serve as a nailing base for all covering material and support the upper floor platforms, which provide the lateral strength along a

Trimmers are installed parallel to the primary floor or ceiling joists and support headers, which run perpendicular to the primary joists. [1] [2] It can also refer to a jack stud that supports a header above a window or door opening. Traditionally, a stud which was less than full length was sometimes referred to as a cripple.

The rim joist depth must match the I-joist size. Mismatches can strain the joist. A similar situation occurs where the I-joist crosses a main beam. Installing squash blocks (2×4 materials 1 ⁄ 16 in or 1.6 mm higher than the I-joist) alongside the I-joists transfers the load from the I-joist onto the beam. Missed nails and glue setting too ...
