PURPOSE: A drain board for constructing an artificial turf playground is provided to facilitate the maintenance work of an artificial turf playground by preventing the assembled drain boards from being separated from each other after construction. CONSTITUTION: A drain board for constructing an artificial turf playground comprises protrusions, first coupling members(18), and second coupling members(20). The protrusions are formed on the surface of a square main body and are composed of frusto-conical hollow legs(22). The first coupling members are formed on the surface of a wing(14) of the main body. Each first coupling member comprises a circular hollow shaft portion(24), a semi-annular latching protrusion portion(32), and a semi-annular slot(34). The circular hollow shaft portion is extended from the top of the wing. The semi-annular latching protrusion portion is formed on the top portion of the circular hollow shaft portion. The semi-annular slot is formed under a portion of the semi-annular latching protrusion portion where meets the circular hollow shaft portion. Each second coupling member corresponding to the first coupling member comprises a semicircular opening(36). |
