DRAINAGE DEVICE FOR SLABS

Abstract

Drainage device (1) for draining liquid from the tread surface (T) of a plate (2) to side surfaces (S) of the plate (2) which adjoin the tread surface (T) with or without a chamfer, comprising a plate-shaped base body (3) which has a flat contact surface for adhesive attachment to a side surface (S) of the plate (2), wherein at least one drainage pin (4A, 4B) projecting at a right angle to the plane of the contact surface is provided at an upper end region of the plate-shaped base body (3) for bearing on the tread surface (T) of the plate (2) or its chamfer.It is proposed that the installation surface is formed by the cover surface (D) of ribs (6) which extend as spacers from a drainage surface (R) of the plate-shaped base body (3), wherein the drainage surface (R) is spaced at a distance from the cover surface (D) and the ribs (6) extend from an upper end region of the plate-shaped base body (3) towards a lower end region of the plate-shaped base body (3).
