The utility model relates to a panel, edge pairs of the panel which are mutually oppositely arranged are provided with fixed shaping parts that are mutually matched into pairs, thus the panels with the same type can be connected at four edges, wherein, the fixed shaping parts of the first edge pair can be spliced and connected by rotating angles, the fixed shaping parts of the second edge pair are designed into complementary hook-shaped elements, a single vertical locking element is arranged on one hook-shaped element of the second edge pairs, at least part of the vertical locking element is extended into a splicing path of the hook-shaped elements, wherein, the vertical locking element is made of plastics, the complementary hook-shaped elements are designed to that when two panels are connected, the panels can be released from the hooked and vertically locked state, at least one panel can surround an axis line which is distributed in the region of the hooked edges to deflect towards the direction which can achieve the release, and working surfaces of the panels are mutually formed with included angles of less than 180 degrees at the release position. In addition, the utility model further relates to a ground paved layer which is composed of the panels. |
