夹板 is a noun with multiple common meanings. The most frequent use is in medicine, referring to a splint for immobilizing an injured limb. In construction and furniture-making, 夹板 often means plywood (a multi-layer board). It can also refer to a clamping board or press plate used in woodworking or manufacturing to hold materials together. A less common meaning is a rack (a framework), but the other senses are far more practical for daily use.
