一种建筑垃圾再生混凝土叠合柱及其施工工艺
摘要：
本发明公开了一种建筑垃圾再生混凝土叠合柱及其施工工艺，建筑垃圾再生混凝土叠合柱柱体包括：再生骨料混凝土预制空心柱、填充于再生骨料混凝土预制空心柱的中心空腔的现浇再生块体混凝土、沿柱长方向设置的于再生骨料混凝土预制空心柱内侧的钢筋笼。本发明整体制作便捷,经济效益高,再生骨料混凝土预制空心柱对现浇的再生块体混凝土产生了环向约束力，有效提高结构的承载能力和改善其变形性能,增加构件的延性。钢筋笼的设计能使再生骨料混凝土预制空心柱与现浇再生块体混凝土之间胶结更紧密，提高柱的整体性，适用于重载、工业厂房、高层建筑和大跨等的柱结构。
摘要（英）：

The invention discloses a construction waste regenerated concrete composite column and a construction process thereof. A column body of the construction waste regenerated concrete composite column comprises a recycled aggregate concrete precast hollow column, cast-in-site regenerated block concrete filled in a central cavity of the recycled aggregate concrete precast hollow column, and a steel reinforcement cage arranged on the inner side of the recycled aggregate concrete precast hollow column in a column length direction. The recycled aggregate concrete precast hollow column provided by the invention is convenient to manufacture wholly and is high in economic benefit, and the recycled aggregate concrete precast hollow column generates circumferential constraining force to the cast-in-site regenerated block concrete, thereby effectively improving the bearing capacity and deformation performance of a structure, and increasing the ductility of a component. The design of the steel reinforcement cage can ensure that the recycled aggregate concrete precast hollow column and the cast-in-site regenerated block concrete are cemented more closely to improve the integrity of the column, so that the construction waste regenerated concrete composite column is suitable for column structures with heavy loads, column structures of industrial plants, column structures of high-rise buildings, long-span column structures, and the like.
