In the framing of a deck or floor system, a rim joist is attached perpendicular to the joists, and provides lateral support for the ends of the joists while capping off the end of the floor or deck system. Rim joists are not to be confused with end joists, which are the first and last joists at the ends of a row of joists that make up a floor ...
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 fast can lead to an uneven or squeaky floor.
A double floor is a floor framed with joists supported by larger timbers.. In traditional timber framing there may be a single set of joists which carry both a floor and ceiling called a single floor (single joist floor, single framed floor) or two sets of joists, one carrying the floor and another carrying the ceiling called a double floor (double framed floor).
The CJ-Series Joists are capable of supporting larger floor or roof loadings due to the attachment of the concrete slab to the top chord of the composite joist. Shear connection between the concrete slab and steel joist is typically made by the welding of shear studs through the steel deck to the underlying CJ-Series Composite Steel Joist. [2]
Structural ironworkers also erect joist girders, bar joists, and trusses, and also install metal decking. When one bullpin is inadequate, the Ratliff Technique [citation needed] may be utilized in order to force a bullpin to align itself straight with a hole, by driving another bullpin or driftpin between a steel member, and the first bullpin.
Solid “bridging” to stabilize floor joists. Blocking placed as attachment points for cabinets, while doubling as bracing against compression of the studs. Blocking (dwang, nog, noggin, and nogging) is the use of short pieces of dimensional lumber in wood framed construction to brace longer members or to provide grounds for fixings.
