Description

The invention relates to kiln wafers of the type used for Passing ceramic ware through a kiln is used during a firing process.

Such kiln cars usually have a supporting structure made of refractory ceramic material on which the goods to be burned are charged; there is the supporting structure made of plate-shaped rack boards that are in their position are clamped relative to the supporting parts of the supporting structure.

This arrangement has the disadvantage that every time a replacement Uieser rack boards ^ required an at least partial dismantling of the supporting parts from the supporting structure and subsequent reassembly of the construction is necessary is.

The invention is therefore based on the object of a kiln car to create that overcomes or reduces these disadvantages. ■■.

At a. Kiln car with a refractory support structure from a multitude of load-bearing parts and a multitude of plate-shaped ones Rack boards this is achieved in that the plate-shaped rack boards are displaceable with the supporting Parts can be brought together in such a way that they are operationally ' ready state can be combined or dismantled with or from these are,

The structural parts can be a variety of essentially have horizontally extending, Q-Östelleboard bearing parts, uie are kept separated from one another in the vertical direction by a plurality of spacers

Preferably, the rack boards can be in supporting parts Longitudinal guide surfaces for driving the Edges of the plate-shaped rack boards when they are inserted in their working position.

The frame boards supporting parts and the spacers can be used with intermediate fixing purposes Formations be provided in their upper and lower surfaces.

The parts supporting the rack boards can be designed as elongated, bar-shaped blocks, and their fixation purposes can consist of one or more Ribs and / or outlines, running in planes,

The spacers may be made of vertically-arranged blocks are made with PiKierungszwecken serving formations, which in turn consist of recesses and / or ribs on their upper and lower side surfaces, and to cooperate with corresponding ribs and / or Aussparun _e en the frame boards carrying parts are suitable. The parts carrying the guide surfaces of the rack boards can be formed by ribs which are part of the pixelation formations.

FIG. 3 shows a rear view of a construction which is essentially identical to those of FIG. 2, but in addition Cross bracing members 24 on v / eist j these extend between the vertical support parts formed by the parts 14 supporting the rack boards and the stand blocks 16 are. The use of such bracing members 24 can be used in a large supporting structure on a kiln car be necessary or desirable; the use of this form of bracing has the advantage that when exposed to If a part of the construction is impacted, the energy is simply distributed to the entire construction by itself occurs, which creates a risk of collapse of the Construction is reduced.

The cross bracing members 24 abut one another at their end faces 26. The end regions of the bracing members have, as shown in particular in FIG. 4, rounded and protruding lugs 28 on their top surfaces and on their Underside surfaces correspondingly rounded groove sections 30j, the lugs 28 and the groove sections 30 are of this type arranged that when the end faces 26 of two adjacent strut members 24, the lugs 28 of these two members together form a rounded rib form, while the two Nutabschnix-te 30 of these two The members jointly form a groove in which a rounded rib of a part 14 carrying the Gesxellbrexter can be received which is arranged immediately below the strut member.

209818/0658

In Figure 5, the interaction of the parts is clearer shown, and it can be seen there that the cross bracing members 24 directly on aar top of a rack board supporting part 14 are arranged so that the ITutabschnitt 30 the rounded rib or protrusion 17 on the surface side of a rack boards part 1'4 picks up. In order to achieve the required height between the part 14, which is supported by a face board, and the next, in vertical direction at a distance, also a part carrying a cell board (not shown in FIG. 5) additional, small spacer blocks 16 are used; and where the bracing member 24 is the one rack board supporting part 14 is crossed, a spacer block 32 that crosses itself is used to increase the stability of the construction used.

In the exemplary embodiment of FIGS. 6 and 7, the construction is not shown in its entirety , since it is essentially the same as that of the preceding figures. The construction shown in FIG. 6 has parts 14 carrying frame boards, which are held at a distance from one another in the vertical direction with the aid of spacer blocks 16 and braced with the aid of transverse bracing elements 24. In FIGS. 6 and 7, the same reference numerals are used for those parts which correspond to the parts shown in the previous figures.

Such pins can also be provided to support a different form of bracing members that are located between adjacent rows of the supporting Extend parts.

Instead of using spacer blocks -16 as a carrier for the adjacent ends of longitudinally successive rack boards supporting members 14t like this is shown in Figure 1, it is possible in a different arrangement, a central, vertically arranged and located in Provide longitudinally extending plate made of ceramic material with circular openings at the points that the frame boards supporting parts 14 correspond ^ the latter could on the plate with the help of cylindrical Pins attached to the ground, which are located through the openings and in the bores 42 of the frame cretter-carrying parts 14 extend.
