1. The set of shaped elements for industrial furnace ceilings, equipped with recesses and protrusions that allow the elements to be connected. Characterized in that: It consists of three equidimensional shaped elements (1, 2 and 3) in the form of wedge-shaped solids. The shaped element (1) has the protrusion (6) in one slanting wall (4). The shaped element (2) has the protrusion (6) in the slanting wall (4), while it has the recess (7) in the opposite slanting wall (5). The shaped element (3) has the recess (7) at one slanting wall (5). The protrusions (6) and recesses (7) of these elements are coaxial with respect to each other. In the front view, they have the shape of a parabola with the arms (8) directed towards the perpendicular wall (9). |
