The invention discloses a fabricated steel structure self-heat-preservation composite concrete
structural system and a forming method. The fabricated steel structure self-heat-preservation composite concrete
structural system comprises foundations, vertical columns, crossbeams, floor slabs, a
shear wall and a roof which are each provided with a steel structural plate, a steel structural column, aheat-preservation layer and a
protection layer. The steel structural plates, the steel structural columns, the heat-preservation
layers and the protection
layers are of an integrated structure, the steel structural plates and the steel structural columns are located in the heat-preservation
layers, and the protection layers are located on the outer sides of the heat-preservation layers. The foundations, the vertical columns, the crossbeams, the floor slabs, the
shear wall and the roof are each provided with a connecting plate and formed by pouring of fabricated
steel structures and self-heat-preservation concrete of various volumes and weights through a special pouring technology according to the different strength and the self-heat-preservation requirements, and the self-heat-preservationconcrete can achieve the effects of fire,
rust,
corrosion and
water resistance, heat preservation and heat insulation.
