This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
檋 combines 木 (tree/wood) with 輂, but the historical development and original meaning are uncertain.
The left side is 木 (tree/wood). The right side 輂 is obscure, but visually it suggests something heavy or wheeled. Without a clear meaning, picture a wooden cart or sled made from trees.
For キョク, imagine a wooden sled (かんじき) that makes a sharp 'kyok' sound as it slides over ice: kyok -> キョク.
