Prefabricated concrete building panels - incorporate reinforcement frames with exposed parts which interengage and over which concrete is cast

摘要

The prefabricated building panels (5,6,10) reinforced by steel frameworks are assembled together by interengaging exposed parts (12) of the frameworks. Concrete is then cast into a cavity defined by the panels themselves over the exposed parts of the frameworks to hold the assembly together. The steel panel sections are placed in position during their fabrication and their structural integrity is assured by keys fitted before connection of the joints.
