Split plate made of densely fired ceramic material.

The invention relates to a split plate for cladding made of tightly fired ceramic material, which is based on the Rear side running parallel to one another, the under-gripping anchoring of the plate in one of the to be disguised Has surface applied mortar or adhesive bed serving elevations or depressions.

The German patent application P 16 59 587.2-25 is a split plate for cladding made of tightly fired ceramic Material has become known, the anchoring that runs parallel to one another on the rear side the plate in a mortar bed attached to the surface to be clad serving in the form of oblique approaches has inclined ribs extending in the longitudinal direction of the plate.

In this known split plate, the ribs are in groups that are inclined alternately to one side and the other combined and each with two plates on the rib

side connecting gap webs provided, which are arranged between the groups of ribs and diamond-like Have cross-section, the weakest cross-section of the gap webs in each case on the back of the plate is located.

The purpose of this measure is to prevent that on the connecting webs after separating the split plate pair Burrs remain in the individual plates that protrude above the highest elevation of the ribs.

These plates have proven themselves, but fall into the individual plates when the pairs of split plates are separated the ridges as thin pins that represent the waste to be cleared. In addition, the spacing is determined by these webs comparatively large between the backs of the split plates, so that there is considerable space during drying and firing the panels are lost in the tunnel kiln.

The invention has set itself the task of improving the gap plates to the effect that no separation whatsoever There is more waste and, on the other hand, it is ensured that the transverse or thickness dimensions of the pair of plates represent a minimum, whereby the filling area available for drying and firing is optimally used can be. Of course, in the split plate according to the invention, one may also be at the break point The remaining ridge does not protrude beyond the furthest height of the anchoring ribs. In addition, the invention seeks to eliminate the cavities on the back of the panels to be kept as small as possible, so that the amount of mortar or adhesive to be used for laying is as small as possible can be kept small.

The problems on which the invention is based arise in the case of a split tile for cladding made of tightly fired

ceramic material that is parallel on the back running towards each other, the underpinning anchoring the plate in a mortar or adhesive bed attached to the surface to be clad serving elevations or has depressions, according to the invention achieved in that the plates of the split plate pair on their Interconnected backsides in the longitudinal direction of the plate, continuous through in the longitudinal direction of the plate as well continuous intermediate webs have connected incisions that form mutually complementary elevations and Guide indentations on the back of the plate.

In a further embodiment of the invention are in at least some dSaser incisions locally widening canals provided, for example, the insertion of the cutting tool when splitting the pair of split plates in the individual plates can serve, but also through their shape fulfill the purpose of anchoring the plates to improve in their mortar or glue bed.

The drawings show in

measured a modified embodiment, but similar to that of FIGS. 3 and 4.

One recognizes from Fig. 1 the two with their rear side lengthways of the intermediate webs 1 cleavage plates 2 adhering to one another, the intermediate webs separate in the longitudinal direction of the split plates continuous incisions 4, which represent sinusoidal wavy lines in the embodiment shown. For the production these incisions, a knife-like core is provided in the press nozzle, as shown in FIG. This core produces projections or depressions on the back of the two plates that are mutually exclusive complete and after separating the two split plates 2, 3 lead along the plane A-A to those ribs, which serve to anchor the split tiles from behind in their mortar or adhesive bed.

3 shows a pair of split plates 12, 13 which adhere to one another at the intermediate webs 11. The cuts 14 are in this embodiment through channels

15 added, which facilitate the insertion of the cutting tool when splitting the plate pair in the individual plates 12, 13.

From Fig. 4 you can see the forming elevations 16 and the resulting depressions 17 and by the Channel 15 formed additional recess. At 18, the separating surfaces are indicated on the intermediate webs 11, wherein it is also shown that the ridges formed during the separation never rise above the height of the elevations

16 extend.

5 shows a core which is used to produce the pattern according to FIGS. 3 and 4, but with a modification this construction, the side flanks of the elevations 16 and 17 when using such a core be designed as diagonally engaging side edges,

as is readily apparent to a person skilled in the art, because the side legs 19 of this core 20 are correspondingly inclined are posed. One can also see the additional core 21, which is used to produce the channel 15. ■

Of course, further configurations of the incisions are also possible according to the principle of the invention, so that the invention is not limited to the illustrated embodiments alone.
