Ribbed ceramic block wall mounting - has ribs and grooves in face against wall inclined to lengthwise axis

摘要

The ceramic block is inserted in wall or ceiling material when still in the plastic state, and comprises two halves fitting together at their rear faces, a smooth-walled head, and ribs and grooves in the remainder of the wall, those on two opposite sides extending at right angles to the block axis. At the side (A) placed against the plastic wall material etc, the bases of the grooves and the head wall are in the same plane, from which the ribs protrude. - On this side, the ribs (13) and grooves (12) are inclined both to the block axis and to the ribs (17) and grooves (16) at right angles to this axis. The plane formed by the head wall (10) and the groove bases is 0 to 4 deg. to the lengthwise axis of the block.
