This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
篖 combines 竹 (bamboo) with 唐, which likely contributes the sound トウ. The exact historical meaning is uncertain, but it may have referred to a bamboo implement or structure.
Bamboo 竹 over 唐 suggests a bamboo object, but the specific meaning is unclear. Imagine an old bamboo tool whose name has been forgotten.
For トウ, picture a tall bamboo tower: tower -> トウ, and the bamboo 竹 rises above the 唐 base.
