DEFINITION

Classification: 52/223.1

WITH COMPONENT HAVING DISCRETE PRESTRESSING MEANS:

(under the class definition) Structure including a compressive preloading of a static structure or portion thereof by either a pre-tensioning or post-tensioning member to reduce or eliminate tensile stress.

SEE OR SEARCH THIS CLASS, SUBCLASS:

222, for a tensioned sheetlike facing.

231, for a related structure having means stretching the reinforcement but not applying compressive stress to the material.

291, for an adjustable stressing means acting to correct warp.

600+, for a module with embedded reinforcement.

721.1+, for a sustainer with a feature for resisting transverse loading; e.g., monolith with eccentric reinforcing.

SEE OR SEARCH CLASS 29, Metal Working,

446+, for a process of assembly and/or joining involving prestressing of a part, particularly subclass 452 for prestressing of a rod, filament, or strand.

264, Plastic and Nonmetallic Article Shaping or Treating: Processes,

228+, for processes there provided for involving precompressing.
