超高层建筑自密实混凝土施工技术运用

Application of Self-compacting Concrete Construction Technology for Super High-rise Steel-concrete Structure

结合实际工程案例,研究超高层工程中钢-混凝土结构中钢柱柱芯自密实混凝土的有效应用,改变了传统超高层钢-混凝土结构普通混凝土浇筑施工,在确保质量的前提下,可大幅度提高整个工程的施工效率和缩短施工工期。结合南山档案服务大厦项目钢-混凝土结构钢柱柱芯自密实混凝土施工,施工效果明显,该施工方法具有可实施性和推广价值,为超高层钢-混凝土结构钢柱施工提供参考经验。

Combined with actual engineering cases,the effective application of steel column core self-compacting concrete in steel-concrete structures in super high-rise projects is studied,and the conventional super high-rise steel-concrete structure ordinary concrete pouring construction is changed.On the premise of ensuring quality,Can greatly improve the construction efficiency of the entire project and shorten the construction period・Combined with the self-compacting construction of steel-concrete structure steel column core of Nanshan Archives Service Building project,the construction effect is obvious.This construction method has practicability and promotion value,and provides reference experience for the construction of super high-rise steel-concrete structure steel column.
