Document Type and Number:
WIPO Patent Application WO/2023/193777
Kind Code:
A1
Abstract:
The present invention relates to a multi-core pressure formed concrete-filled steel tube laminated component. The multi-core pressure formed concrete-filled steel tube laminated component comprises at least two pressure formed concrete-filled steel tube core columns, stirrups and peripheral concrete; the pressure formed concrete-filled steel tube core column comprises a steel tube, pressure formed concrete poured in the steel tube and a fiber composite material wrapping the steel tube; the pressure formed concrete applies pressure to the concrete in a concrete curing process; the stirrups are bound to the peripheries of the at least two pressure formed concrete-filled steel tube core columns; the peripheral concrete is poured outside the bound pressure formed concrete-filled steel tube core columns to wrap the pressure formed concrete-filled steel tube core columns. The multi-core pressure formed concrete-filled steel tube laminated component of the present invention is high in bearing capacity, good in forming quality, good in fire resistance and low in construction difficulty.
