Large-hollow-rate conical hollow interlayer steel pipe recycled concrete member and preparation method thereof
The invention relates to the technical field of engineering structures, and particularly discloses a large-hollow-rate conical hollow interlayer steel pipe recycled concrete member and a preparation method thereof.The large-hollow-rate conical hollow interlayer steel pipe recycled concrete member comprises an outer steel pipe and an inner steel pipe, and four partition plates serving as positioning side supports and shear keys are evenly arranged between the outer steel pipe and the inner steel pipe; self-compacting recycled concrete is poured among the outer steel pipe, the inner steel pipe and the partition plate. Component end plates are arranged at the top and the bottom of the outer steel pipe; the outer steel pipe, the inner steel pipe and the self-compacting recycled concrete form a conical component. The outer steel pipe not only can bear the external load effect, but also can restrain the interlayer self-compacting recycled concrete and protect the inner-layer steel pipe from being eroded by the external environment, the use amount of materials is greatly reduced through the large hollow rate and the variable cross-section taper, and the manufacturing cost is reduced; the interlayer recycled concrete is divided into four cavities through the partition plate structure with holes, and the defect that the combination effect of the recycled concrete and the steel pipe is reduced due to application of the large hollow rate is greatly overcome.
本发明涉及工程结构技术领域，具体公开了一种大空心率锥形中空夹层钢管再生混凝土构件及其制备方法，包括外钢管和内钢管，所述外钢管和内钢管之间均匀设置有作为定位侧撑和剪力键的四个隔板，外钢管、内钢管和隔板之间浇筑自密实再生混凝土；所述外钢管的顶部和底部均设置有构件端板；外钢管和内钢管以及自密实再生混凝土构成锥形构件。本发明的外钢管不仅可以承受外部荷载作用，还可以约束夹层自密实再生混凝土并保护内层钢管免受外界环境的侵蚀，大空心率与变截面锥形的使用极大地减少了材料用量，降低了造价；带孔的隔板构造将夹层再生混凝土分隔成四个空腔，极大地弥补了大空心率应用所导致再生混凝土与钢管组合作用的降低。
