The invention provides an internal octagonal inner-poured concrete composite column which comprises steel plates and corner steel pipes, wherein a plurality of corner steel pipes are uniformly arranged; one steel plate is arranged between every two adjacent corner steel pipes to form a hollow columnar structure; each corner steel pipe is a right triangular corner steel pipe, two base angles of theright triangular corner steel pipe are chamfers, and the section of each chamfer is fixedly connected with the side wall of the steel pipe in a welding mode; and the three angles of the right triangular corner steel pipe form edge constraint by the stability of a triangle, meanwhile the two sides of the steel pipe connected with the triangular corner steel pipes are bound by the triangular cornersteel pipes, and thus the compression capacity of the composite column is greatly increased. Therefore, in the same external size, the width-to-thickness ratio of the internal octagonal composite column can be reduced by nearly half compared with the ordinary box column, and therefore under the condition of obtaining the same moment of inertia, the amount of steel used in the section can be reduced by 20-30%. Thus, the amount of steel used is significantly reduced, and the economic benefit is obviously increased.
本发明提出一种内八角内浇混凝土组合柱，包括钢板和角部钢管，多根角部钢管均匀布置；相邻两根角部钢管之间均设有一块钢板，以围成一空心的柱状结构，角部钢管为直角三角形角部钢管，直角三角形角部钢管的两个底角均为倒角，倒角的剖面与钢板的侧壁之间通过焊接固定连接；三角形角部钢管的三个角依靠三角形的稳定性形成边缘约束，同时也使连接三角形角部钢管的钢板的两侧被三角形角部钢管所束缚，从而大大增加组合柱的受压能力，因此，相同外部尺寸的柱子，内八角形的组合柱的宽厚比相比普通的箱型柱，可以减少接近一半，从而在获得相同惯性矩的情况下，截面用钢量减少20～30％，从而显著降低用钢量，经济效益明显升高。
