Recycled concrete-filled steel tube column

Abstract

Disclosed is a recycled concrete-filled steel tube column, which relates to the technical field of construction. The recycled concrete-filled steel tube column includes an outer steel tube, an inner steel tube, and adhesive, where the inner steel tube is sleeved with the outer steel tube, a gap between the inner steel tube and the outer steel tube is filled with recycled concrete, and an outer wall of the inner steel tube and an inner wall of the outer steel tube are both coated with the adhesive. The present invention effectively utilizes recycled concrete, significantly conserves energy, and promotes the use of recycled resources, thereby achieving a strategic goal of green manufacturing and sustainable development. Meanwhile, the adoption of two layers of steel tubes not only reduces material consumption but also enhances the strength of the recycled concrete-filled steel tube column.
