ABSTRACT:
The present invention includes a plurality of ceramic oxide wall panels which are defined by a thickness dimension, depth dimension, and width dimension. The ceramic oxide panels are beveled along their width sides so that when they are held together along their width sides, they form a closed plane, that is a polygon or a substantial circle configuration. At each abutment position of two adjacent wall panels, there is formed an abutment angle. In addition a plurality of overlap support panels of ceramic oxide is employed and each is formed to have an angle which fits over an associated one of said abutment angles. Each overlap support panel is secured to, and partially overlays, two abutting wall panels, thus providing support for said two adjacent abutting wall panels. In a preferred embodiment each overlap support panel abuts two adjacent support panels. In addition, at each location where two overlap support panels are in abutment, there is located a second support member arranged to bridge the abutting edges of the adjacent overlap support panels. Further, in addition, there is a ring member which is located to lie around the periphery of the package of panels coming in touch with the apexes of the said angles of the overlap support panels and coming in touch with the outer surfaces of the second support members.
