Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters
What is claimed is:
1. A support for a wagon superstructure for supporting molded blanks of ceramic material which are to be fired, comprising a planar hollow-section grid structure, which is formed from interconnected webs and is made from a silicon carbide material with a multiplicity of openings and a plurality of bearing pieces for inserting in appropriate openings corresponding to desired support positions for a specific molded-blank shape, said bearing pieces being fixed in position in said openings.
2. The support as claimed in claim 1, wherein the bearing pieces have at the bottom, on each of two opposite sides, a lateral extension which can be guided through the opening.
3. The support as claimed in claim 2, wherein mutually opposite webs which delimit the openings have fit-through recesses, through which the lateral extensions of the bearing piece can be fitted into the opening.
4. The support as claimed in claim 1, wherein inserts which can be fitted into openings in the grid structure are provided in order to allow supports to be stacked horizontally above one another.
5. The support as claimed in claim 4, wherein the inserts can be fixed in position.
6. The support as claimed in claim 1, wherein supporting projections, which project essentially perpendicularly upward from the plane of the grid structure, for the molded blank are provided on one side.
7. The support as claimed in claim 1, wherein the bearing pieces are hollow.
8. The support as claimed in claim 1, wherein the molded blanks are tile blanks.
9. A wagon superstructure of a kiln wagon for supporting molded blanks of ceramic material which are to be fired, comprising a multitude of supports having a planar hollow-section grid structure, which is formed from interconnected webs and is made from a silicon carbide material with a multiplicity of openings and a plurality of bearing pieces for inserting in appropriate openings corresponding to desired support positions for a specific molded-blank shape, said bearing pieces being fixed in position in said openings.
10. The wagon superstructure as claimed in claim 9, further comprising parallel, horizontally arranged bars for supporting the supports.
