Fabricated building load-bearing heat-preserving wallboard of end prefabricated steel tanks

The utility model relates to a fabricated building load-bearing heat-preserving wallboard of end prefabricated steel tanks and belongs to the technical field of fabricated building load-bearing heat-preserving wallboard structures. The wallboard comprises an upper layer rigid veneer and a lower layer rigid veneer, wherein the upper layer rigid veneer and the lower layer rigid veneer have a load-bearing function, a polyurethane layer made of a polyurethane material is arranged between the upper layer rigid veneer and the lower layer rigid veneer, one side of the polyurethane layer which is along the long side of rigid veneers is in a trapezoid concave design, the other side of the polyurethane layer is in a trapezoid protrusion design, and a steel tank serving as a load-bearing stress surface is fixed on an end of the top of the fabricated building load-bearing heat-preserving wallboard. The wallboard is convenient to disassemble and assemble, reliable in heat preservation performance, excellent in load-bearin
