Abstract
The surface drain has a cup-shaped drain body (14) which is securely cast into a concrete slab (10). A cylindrical inset (20) in form of a disk is fitted in the concrete slab and rotatable about the axis of the drain body. Fitted in the disk is also a rotatable cylindrical part (31) of a square frame (30) which receives a grate. When laying the tiles, the square sides of the grate frame can be set parallel to the joints of the tiles by turning the grate frame. Since the cylindrical inset (20) has an eccentric inner cylinder (24) for receiving the cylinder (31), a turning of the cylindrical inset in the concrete slab permits the square sides of the grate to coincide with the coordinates of the tile joints.
