Abstract
A concrete structure is lined with a statically self-supporting glass shell composed of shell segments which are themselves joined together by sealing strips. In a pipe embodiment of the invention, the shell segments form a ring spaced from the concrete body with the spacing being filled by a backfill mass so that a compressive prestress is provided to the arch shape. When used in a container, the shell may be a laminate of two or more glass layers bonded full surface together.
Claims16
A pipe assembly, comprising:
- a tubular concrete support forming a cylindrical wall;
- a plurality of glass shell segments having juxta posed edges and lining said wall, said edges forming axially extending and circumferentially extending gaps having intersections at crossings of said gaps;
- means for joining said glass shell segments along said edges into a statically unitary shell forming a space with said wall and including axially extending sealing strips filling said axially extending gaps and braced between the edges defining same, circumferential arc segmental sealing strips braced between the edges defining said circumferentially extending gaps, and sealing bodies filling said intersections and sealingly engaging said strips;
- and
- compensating means including a backfilling mass filling said space between said shell and said wall and interposed between said strips and said wall for supporting said shell on said wall with limited relative freedom of movement of said shell and said support while exerting annular compressive force on said shell and said axially extending strips whereby an arch is formed by said segments and said axially extending strips.
