My Flashcards

Definition

Meaning

A structural support running horizontally across the width of a ship's deck to provide strength and rigidity.

In naval architecture, a primary transverse structural member that supports the deck planking and distributes loads to the frames or hull. In broader construction contexts, it may refer to a similar load-bearing beam in a platform or flat roof structure.

Linguistics

Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

  • Прямой перевод "палубный луч" будет ошибкой. Здесь "beam" означает балку, брус, перекладину, а не луч света.
  • Не путать с "deck board" (палубная доска настила) – "beam" это несущая конструкция под досками.

Common Mistakes

  • Using 'deck beam' to refer to a railing or handrail (which is a 'guardrail').
  • Confusing it with 'keel' (the central backbone along the bottom of the hull).
  • Using it as a verb.
