The invention relates to a split plate for cladding made of fired ceramic material, which is based on the Rear side running parallel to each other, the anchoring of the separate individual plates in a mortar or Has elevations or depressions serving adhesive bed.

DE-OS 16 59 587 discloses a split plate for cladding made of fired ceramic material known, the parallel to each other on aer back, the backgreü ends anchoring the Separate single slab in a mortar bed serving approaches in the form of obliquely inclined, in the longitudinal direction of the slab having running ribs.

In this known split plate, the ribs are to alternate to one side or the other inclined groups combined and each connecting with two individual plates on the rib side Provided webs which are arranged between the groups of ribs and rhombic cross-section have, with the weakest cross-section of the webs in each case being on the rear side of the individual panels. The purpose of this measure is to prevent that on the connecting webs after dividing the Split plate in the two individual plates burrs remain, which are above the highest elevation of the ribs protrude.

When splitting, the webs accumulate as strip-shaped waste. In addition, the Distance between the backs of the individual panels is comparatively large, so that there is a considerable amount of space when Drying and firing of the split tiles in the tunnel kiln is lost

The invention is based on the object of improving this known split plate to the effect that no more waste occurs when separating and, on the other hand, it is ensured that the thickness of the split plate is kept as small as possible, around the area available for drying and firing to make optimal use of it. In addition, a burr that may remain at the break point should not be over the the furthest protruding anchoring ribs protrude.

The object on which the invention is based corresponds to that in the characterizing part of the patent claim 1 specified features solved, The advantages achieved with the solvents are that the disadvantages indicated are avoided.

In a further embodiment of the invention, they are local in at least some of these separating cuts widening channels provided, for example, the insertion of the cutting tool when splitting the Split plate ir. The individual plates can serve, but also fulfill the purpose through their shape Anchoring the panels in their mortar or adhesive bed to be improved.

The drawing, in which exemplary embodiments of the invention are shown, shows in

1 shows a partial front view of a split plate,

F i g. 2 a knife-like core for producing the separating cuts that are continuous in the longitudinal direction of the split plate in the case of the split plate according to FIG. 1,

F i g. 3 is a partial front view of a modified embodiment;

FIG. 4 shows a partial section of a separated individual plate of the split plate according to FIG. 3 in front view and

F i g. 5 shows a core for producing separating cuts according to the modified embodiment, however similar to that of FIGS. 3 and 4.

1 shows the two individual plates 2, 3 of a split plate connected to one another on their rear sides along the intermediate webs 1. Between the intermediate webs 1, continuous separating cuts 4 are provided in the longitudinal direction of the gap plate, which in the embodiment shown have the shape of sinusoidal wavy lines. To produce these separating cuts, a knife-like core 10 is provided in the press nozzle of an extruder, as shown in FIG. 2 is shown Through this core 10 projections or depressions are generated on the backs of the two individual plates 2, 3, which complement each other and after separating the two individual plates 2, 3 along the plane AA lead to the ripper that engages behind the anchoring serve the individual plates 2, 3 in their mortar or adhesive bed.

In Fig. 3 is a split plate, consisting of the individual plates 12, 13 reproduced, which via intermediate webs 11 are connected to each other. In this embodiment, the separating cuts 14 are through channels 15 added, which facilitate the use of the cutting tool to split the split plate.

From Fig. 4 one can see the elevations that are formed 16 and depressions 17 and one of the additional depressions formed by the channel i5. At 18 the dividing surfaces of the split intermediate webs 11 are indicated, which is also shown. that the The elevation of the ridges forming the separation does not extend beyond the height of the elevations 16.

In Fig. 5 shows a core 20 which is used for producing the separating web shape according to FIGS. 3 and 4 is used, but in a modification of this form, the side flanks of the elevations 16 or depressions 17 forming strip-shaped surfaces when using this core 20 as rear-engaging side edges be formed because the side legs 19 of this core 20 connect at an acute angle. One also recognizes the additional core 21, which is used to produce a channel 15.

Of course, according to the principle of the invention, other foi men for the separating cuts are also possible, see above that the invention is not limited to these embodiments
