Abstract
Abstract This invention relates to the preparation and packaging of refractory blocks into prefabricated panel units for transportation to a site, a refractory wall constructed of the prefabricated units and the method of forming a wall. The blocks, in a panel unit, are supported upon a pallet, enclosed by a relatively moisture-tight wrapper, and bound to a structure for lifting the stack of blocks. The panel units are adapted to be positioned in abutting relation, lateral and vertical, with each other and preferably include wedge-shaped blocks at prescribed locations for facilitating erection of a wall adjacent a support structure.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
133 words
A package containing refractory blocks for transportation to a desired location for forming a monolithic wall comprising: a base support means, a plurality of massive plastic refractory blocks stacked on said support means, certain of said blocks being fired, and other blocks being unfired, a pair of complementary wedge shaped blocks, being located at each corner of the top of the stacked blocks, at least the outer of said pair being a fired block, lifting means being supported by said blocks, corner reinforcing means positioned to engage said fired blocks, and binding means surrounding said blocks and said lifting means whereby said blocks and said lifting means are rigidly united by said binding means, said pairs of blocks being located so as to urge the top of said stacked blocks into stacked alignment.
Claim 2
Dependent Claim
133 words
A package containing refractory blocks for transportation to a desired location for forming a monolithic wall comprising: a base support means, a plurality of massive plastic refractory blocks stacked on said support means, certain of said blocks being fired, and other blocks being unfired, a pair of complementary wedge shaped blocks, being located at each corner of the top of the stacked blocks, at least the outer of said pair being a fired block, lifting means being supported by said blocks, corner reinforcing means positioned to engage said fired blocks, and binding means surrounding said blocks and said lifting means whereby said blocks and said lifting means are rigidly united by said binding means, said pairs of blocks being located so as to urge the top of said stacked blocks into stacked alignment.
Claim 3
Dependent Claim
26 words
A package containing refractory blocks for transportation to a desired location as claimed in claim 1, wherein said wedge-shaped blocks define apertures for receiving anchoring means.
Claim 4
Dependent Claim
24 words
A package of refractory blocks for transportation to a desired location as claimed in claim 1, and further including cover means encompassing said blocks.
Claim 5
Dependent Claim
26 words
A package of refractory blocks for transportation to a desired location as claimed in claim 1, wherein said plastic blocks consist of pyrophyllite and plastic clay.
Claim 6
Dependent Claim
41 words
A package of refractory blocks as receited in claim 1, and further including a second plurality of blocks on said base support bound to a second panel lifting means independently of the first named plurality of blocks and panel lifting means.
