Equilateral three-limb combined column structure of ultra-high performance concrete sleeve

The utility model relates to an equilateral three-limb combined column structure of an ultra-high performance concrete sleeve. Wherein the three column limbs are distributed in an equilateral triangleshape, and the reinforced ultra-high performance concrete slab is connected between any two column limbs. Each column limb comprises a concrete-filled steel tube column and an ultra-high performanceconcrete sleeve arranged on the peripheral side of the concrete-filled steel tube column in a sleeving mode, the concrete-filled steel tube column comprises H-shaped steel and column limb concrete, and the column limb concrete is poured on the outer side of the H-shaped steel with the ultra-high performance concrete sleeve as a formwork. The reinforced ultra-high-performance concrete plate comprises a reinforced bar and a filled ultra-high-performance concrete layer, and the two ends of the reinforced bar are welded and fixed to the adjacent H-shaped steel. By adopting the ultra-high performance concrete sleeve and the
