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.
They serve as a stiffening element for the stability of a design. This brace could also be an ordinary cross-section wooden cross-beam, or even a board. Cross bracing can be seen in situations like flooring, where cross braces are put between floor joists in order to prevent movement.
In the construction of masonry buildings, a fire cut [1] or fireman's cut is a diagonal chamfer of the end of a joist or beam where it enters a masonry wall. If the joist burns through somewhere along its length, damage to the wall is prevented as the fire cut allows the joist to fail and still leave the masonry wall standing.
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).
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. [3]
A thin but stiff board is then glued to the inside of both the front and back cover of the book, and the entire book is trimmed slightly on the head, tail, and fore edge, often with an electric guillotine. Stiffening provides an in-house, inexpensive alternative to commercial library binding for paperbacks. While it does not involve (re-)sewing ...

Wood or steel floor frames usually include a rim joist around the perimeter of a system of floor joists, and often include bridging material near the center of a span to prevent lateral buckling of the spanning members. In two-story construction, openings are left in the floor system for a stairwell, in which stair risers and treads are most ...
