Hollow interlayer stiffening rib concrete-filled steel tubular column
The invention discloses a hollow interlayer stiffening rib concrete-filled steel tubular column. The hollow interlayer stiffening rib concrete-filled steel tubular column comprises an inner steel tube, an outer steel tube and four stiffening ribs arranged on each of the outer side of the inner steel tube and the inner side of the outer steel tube, wherein the space between the inner steel tube and the outer steel tube is filled with concrete, and the stiffening ribs are embedded in the outer side of the inner steel tube and the inner side of the outer steel tube and extend in the height direction of the steel tubes. According to the hollow interlayer stiffening rib concrete-filled steel tubular column, the outer side of the inner steel tube and the inner side of the outer steel tube are each provided with four stiffening ribs, the hollow interlayer concrete-filled steel tubular column with the stiffening ribs is formed, local buckling of the tube wall is delayed, restraint of the tube wall to concrete is enhanced, the integrity is good, the joint working performance of the steel tubes and the concrete is improved, and meanwhile the fire resistance of components is improved.
本发明公开了一种中空夹层加劲肋钢管混凝土柱，中空夹层加劲肋钢管混凝土柱包括：内钢管、外钢管、内钢管外侧与外钢管内侧各设的4条加劲肋，内钢管与外钢管之间的空间内填充混凝土，加劲肋嵌设于内钢管外侧与外钢管内侧并沿钢管的高度方向延伸。本发明在内钢管外侧与外钢管内侧各设有4条加劲肋,形成带劲肋中空夹层钢管混凝土柱,延缓管壁局部屈曲,增强管壁对混凝土的约束,整体性好,有利于提高钢管和混凝土的共同工作性能,同时还有利于提高构件的抗火性能。
