Block form for reinforced concrete structure - uses laterally extending sheet metal frames to support spaced parallel thin-walled tubes

摘要

The upper and lower ends of the tubes are supported by laterally extending sheet metal frames which leave the tube ends open. The upper frame has an upward opening channel shaped cross-section. A pair of wall panels which form the inner and outer wall surfaces of the completed structure sandwich the tubes and extend between the frames. The volume between the panels, exterior of the tubes, is filled with a lightweight thermal insulation. In the completed structure, the tubes are filled with reinforced concrete to form the columns for the structure and interconnected by horizontal reinforced concrete bond beams poured in the upper frame members.
